Description

Title

Coordination of terminal-initiated reporting

Field

Various example embodiments relate to coordination of terminal-initiated reporting. More specifically, various example embodiments exemplarily relate to measures (including methods, apparatuses and computer program products) for realizing coordination of terminal-initiated reporting.

Background

The present specification generally relates to reporting related to radio conditions experienced by terminals, mobile stations, modems, or user equipments (UE), such as a smartphone, and the like.

Such reporting may for example be channel state information (CSI) reporting, layer 1 reporting, beam reporting, and the like.

Such reporting may for example relate to multiple input multiple output (MIMO) / beam management (BM).

Such reporting may be periodic reporting, were a terminal (always) repeatedly measures a reference signal and periodically reports in predetermined periodic radio resources irrespective of whether reporting was actually necessary (i.e., irrespective of whether there are e.g. changes in a radio condition experienced), aperiodic reporting, where a terminal, once it is triggered to report, measures a reference signal and reports once, and semi- persistent reporting, where a terminal, once it is triggered to report, repeatedly measures a reference signal and periodically reports in predetermined periodic radio resources until it is released from reporting (i.e., semi-persistent reporting is a kind of mix of periodic and aperiodic reporting). On the other hand, such reporting may be terminal-initiated, e.g. event- driven, where the event may be detection of a predetermined condition.

For such terminal-initiated reporting, the terminal must be provided/scheduled with resources enabling the terminal to actually transmit the data to be reported.

Such resource scheduling is accompanied with management overhead, resource waste, and communication latency, as both parties involved in the reporting, the terminal and a network node providing access to a network must be aware of the resources (to be) used by the terminal for the reporting.

Hence, the problem arises that e.g. management overhead, resource waste, and communication latency are detrimental to operation of a mobile network both for the involved terminal itself but also for the overall network and affected other terminals.

Hence, there is a need to provide for coordination of terminal-initiated reporting.

Various example embodiments aim at addressing at least part of the above issues and/or problems and drawbacks.

Detailed description

The present disclosure is described herein with reference to particular nonlimiting examples and to what are presently considered to be conceivable embodiments. A person skilled in the art will appreciate that the disclosure is by no means limited to these examples, and may be more broadly applied.

It is to be noted that the following description of the present disclosure and its embodiments mainly refers to specifications being used as non-limiting examples for certain exemplary network configurations and deployments. Namely, the present disclosure and its embodiments are mainly described in relation to 3GPP specifications being used as non-limiting examples for certain exemplary network configurations and deployments. As such, the description of example embodiments given herein specifically refers to terminology which is directly related thereto. Such terminology is only used in the context of the presented non-limiting examples, and does naturally not limit the disclosure in any way. Rather, any other communication or communication related system deployment, etc. may also be utilized as long as compliant with the features described herein.

Hereinafter, various embodiments and implementations of the present disclosure and its aspects or embodiments are described using several variants and/or alternatives. It is generally noted that, according to certain needs and constraints, all of the described variants and/or alternatives may be provided alone or in any conceivable combination (also including combinations of individual features of the various variants and/or alternatives).

As used herein, "at least one of the following: <a list of two or more elements>" and "at least one of <a list of two or more elements>" and similar wording, where the list of two or more elements are joined by "and" or "or", mean at least any one of the elements, or at least any two or more of the elements, or at least all the elements.

According to example embodiments, in general terms, there are provided measures and mechanisms for (enabling/realizing) coordination of terminal- initiated reporting.

Terminal-initiated reporting (or UE-initiated reporting or UE event driven reporting) provides advantages regarding resource utilization and configuration flexibility. One example application of terminal-initiated reporting (or UE-initiated reporting or UE event driven reporting) is UE-initiated/event-driven beam management (MIMO/BM).

Advantageously, control thereof is facilitated leveraging (as much as possible) 3^rd Generation Partnership Project (3GPP) legacy CSI measurement and reporting configuration frameworks, targeting frequency range 2 (FR2) and single transmission/reception point (sTRP) with intra- and inter-cell beam management.

Furthermore, one of the objectives of 3GPP NR. Rel-release 19 mobility enhancements is to specify necessary components to support event triggered layer 1 (LI) measurement reporting (such as CSI reporting but not limited to it) for L1/L2 triggered mobility (LTM), which may be L1/L2 centric mobility, lower layer triggered mobility, L2 mobility.

Heretofore, uplink (UL) signaling content(s) (and procedure(s) as required) for UE-initiated/event-driven beam reporting facilitating fast beam switching and also UL signaling medium/container considering the UE-initiated/event- driven nature of the UL transmission, designed primarily for the purpose of beam reporting, are to be defined.

In this regard, in relation to MIMO/BM the following is conceivable:

For terminal-initiated reporting (or UE-initiated reporting or UE event driven reporting), a terminal/UE has to detect a trigger-event for beam reporting. In view thereof, the terminal/UE may monitor a reference signal (RS) (or a plurality of RSs) to assess if a beam-reporting trigger condition has been met.

Further, for terminal-initiated reporting (or UE-initiated reporting or UE event driven reporting), a terminal/UE has to transmit a beam-report, with the content of the beam report being indicative of the experienced radio condition, and with the signaling medium/container for beam report transmission being, for example, a medium access control control element

(MAC-CE) or uplink control information (UCI).

UE-initiated/event-driven beam reporting may be implemented utilizing a concept according to which the UE requests UL resource(s) for the beam report (and the network grants/schedules such UL resource(s)), a concept according to which a UE notifies beforehand transmission of a beam report, and a concept where the network (e.g. a gNB preconfigures UL resources for the UE's beam report.

As discussed above, reporting may be performed using periodic reporting, aperiodic reporting, and semi-persistent reporting.

These concepts are explained below with reference to layer 1 (LI) reference signal received power (R.SR.P) reporting according to a CSI framework.

As mentioned, such frameworks may be leveraged/utilized as much as possible also for terminal-initiated reporting (or UE-initiated reporting or UE event driven reporting). Leverage/utilization thereof as much as possible may be aimed for.

According to this framework, procedures on aperiodic CSI reporting assume that the CSI reporting is triggered by DCI format 0_l, but they equally apply to CSI reporting triggered by DCI format 0_2, by applying higher layer parameter reportTriggerSizeDCI-0-2 instead of reportTriggerSize. Procedures on aperiodic CSI reporting further assume that the CSI reporting is triggered by DCI format 0_l, but they equally apply to CSI reporting triggered by DCI format 0_3.

According to this framework, further, the time and frequency resources that can be used by the UE to report CSI are controlled by the gNB. CSI may consist of channel quality indicator (CQI), precoding matrix indicator (PMI), CSI-R.S resource indicator (CRI), SS/PBCH block resource indicator (SSBR.I), layer indicator (LI), rank indicator (RI), Ll-RSRP, Ll-SINR, Capabilityindex or time-domain channel properties (TDCP).

According to this framework, further, each reporting setting CSI-ReportConfig is associated with a single downlink bandwidth part (BWP) (indicated by higher layer parameter BWP-Id) given in the associated CSI-ResourceConfig for channel measurement and contains the parameter(s) for one CSI reporting band: codebook configuration including codebook subset restriction, time-domain behavior, frequency granularity for CQI and PMI, measurement restriction configurations, and the CSI-related quantities to be reported by the UE such as the LI, Ll-RSRP, Ll-SINR, CRI, SSBRI, Capabilityindex and TDCP.

According to this framework, further, the time domain behavior of the CSI- ReportConfig is indicated by the higher layer parameter reportConfigType and can be set to 'aperiodic', 'semiPersistentOnPUCCH', 'semiPersistentOnPUSCH', or 'periodic'. For 'periodic' and 'semiPersistentOnPUCCH'/'semiPersistentOnPUSCH' CSI reporting, the configured periodicity and slot offset applies in the numerology of the UL BWP in which the CSI report is configured to be transmitted on. The higher layer parameter reportQuantity indicates the CSI-related, Ll-RSRP-related, Ll- SINR-related, Capabilitylndex-related or TDCP-related quantities to report.

According to this framework, further, each CSI resource setting CSI- ResourceConfig contains a configuration of a list of SSsl CSI resource sets (given by higher layer parameter csi-RS-ResourceSetList), where the list is comprised of references to either or both of NZP CSI-RS resource set(s) and SS/PBCH block set(s) or the list is comprised of references to CSI-IM resource set(s). Each CSI resource setting is located in the DL BWP identified by the higher layer parameter BWP-id, and all CSI resource settings linked to a CSI report setting have the same DL BWP. As further mentioned above, UE-initiated/event-driven beam reporting may be implemented utilizing a concept according to which a UE notifies beforehand transmission of a beam report.

This may be implemented with periodic UL resources which may be utilized by the terminal/UE for the report such that the terminal/UE only has to indicated beforehand that it intends to transmit a report in the provided UL resources.

However, in such implementation, it is still undefined how both parties know which UL resources are actually (to be) used by the terminal/UE. However, agreement on the UL resources actually (to be) used by the terminal/UE would be advantageous, since otherwise, on the one hand, the network (e.g. gNB has (after the UE notification) to listen on all possible UL resources (periodic UL resources) for whether the terminal/UE has utilized these resources for the report, and on the other hand, all possible UL resources (periodic UL resources) have to be kept free for use by the terminal/UE (i.e., cannot be scheduled for other terminals.

In other words, in such implementation, it is still undefined how the terminal's notification of an intended beam report (i.e. the UL signal used for indicating reporting event ) maps or associates to uplink resources used for carrying the report.

One example scenario is depicted in FIG. 9. FIG. 9 shows a schematic diagram illustrating relationships between uplink resources according to example embodiments, and in particular illustrates an example of reporting resource configuration and UL signaling occasion configuration. As is illustrated in FIG.

9, there may be periodical UL signaling occasions and periodical UL resources, where again, it is still undefined how the terminal's notification of an intended beam report (i.e. the UL signal used for indicating reporting event ) maps or associates to uplink resources used for carrying the report. In FIG. 9, UL signaling occasions (occasions for transmitting the notification, e.g. once reporting necessity is triggered by an event) are indicated with "91" (exemplary 91a, 91b, etc.), and reporting occasions (resources where the actual report might be transmitted) are indicated with "92" (exemplary 92a, 92b, etc.).

This naming scheme is maintained also for FIG. 10 to FIG. 13.

If no intention to transmit any report is indicated in e.g. signaling occasion 91a, the subsequent reporting occasion resources may be scheduled by the network (e.g. gNB) for other purposes other than terminal-initiated reporting by the considered terminal.

In view of the above, in brief, according to example embodiments, parameters are (at least one parameter is) provided wherein the parameters (the at least one parameter) configure(s) the time domain characteristic between the UL signal indicating the use of UL resource and the reporting UL resource for event triggered reporting.

Namely, according to example embodiments, a parameter (named herein N1 or first parameter) configures the associated reporting occasion in relation with the periodical reporting occasions occurring in relation with the UL signaling occasion.

The value of the first parameter may have values Nl=0,l,2,3,... (or alternatively Nl= 1,2,3,...), wherein the first parameter indicates the Nth reporting occasion after (or with respect to) the UL signaling occasion in which the corresponding report is to be transmitted.

FIG. 10 shows a schematic diagram illustrating relationships between uplink resources and possible resource selection results according to example embodiments, and in particular illustrates exemplary associations of UL resources (reporting occasions) with an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event).

In particular, FIG. 10 schematically illustrates which UL resource (reporting occasion) following an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a is associated with the UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a based on the value of the first parameter Nl.

Further, according to example embodiments, a parameter (named herein N2 or second parameter) associated with an UL resource for reporting event triggered information may indicate how many (that may be consecutive) reporting occasions (that may be consecutive reporting occasions) can be/are used for reporting information for the event.

FIG. 12 shows a schematic diagram illustrating relationships between uplink resources and possible resource selection results according to example embodiments, and in particular illustrates exemplary associations of UL resources (reporting occasions) with an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event).

In particular, FIG. 12 schematically illustrates which UL resources (reporting occasions), namely two (92a, 92b) in the present case of "N2 = 2", following an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a are associated with the UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a based on the value of the second parameter N2.

Further, according to example embodiments, a parameter (named herein N3 or third parameter) associated with an UL resource for reporting event- triggered information may indicate a configuration of non-consecutive reporting occasions can/are used for reporting information for the event.

The third parameter may be enriched by (an) additionally provided fourth and/or fifth parameter(s) explained below in detail.

While the parameters are numbered (first parameter, second parameter, ..., fifth parameter), these parameters are mutually optional, and the numbering thereof is only for distinguishing one from the other. That is, presence or definition or configuration with e.g. the third parameter does not necessitate presence or definition or configuration with e.g. the first parameter and the second parameter.

According to example embodiments, the para meter/ para meters is/are configured as part of the reporting configuration. That is, the network (e.g. a gNB) may provide a configuration (which may be a reporting related configuration) to a terminal which includes a configuration of the parameter or parameters. The terminal, with respect to terminal-initiated reporting, may apply/refer to this configuration and in particular the configured parameter(s).

According to further example embodiments, the parameter(s) is/are event specifically configured or applied for all event based reporting configurations. In other words, a parameter configuration for a first event (triggering reporting of e.g. a first metric) may differ from a parameter configuration for a second event (triggering reporting of e.g. a second metric).

According to further example embodiments, said at least one configured reporting parameter is indicative of a relationship between notification occasion resources utilized for said notification and said reporting resources to be used for transmission of said radio condition report.

Apart from that, the apparatus of FIG. 5 may be seen as counterpart of the apparatus of FIG. 3 or 4. As such, the remaining functionality of the apparatus of FIG. 5 emerges from the description of the apparatus of FIG. 3 or 4 above in such a way that transmissions of the apparatus of FIG. 3 or 4 may terminate at the apparatus of FIG. 5 and be processed at the apparatus of FIG. 5, and that transmissions of the apparatus of FIG. 5 may terminate at the apparatus of FIG. 3 or 4 and be processed at the apparatus of FIG. 3 or

4, and that exchanged information have same characteristics on both sides.

Example embodiments outlined and specified above are explained below in more specific terms.

According to example embodiments, the value Nl, i.e., the first parameter, is configured by R.R.C.

According to further example embodiments, either of the values Nl, N2, N3, N3-non-consecutive, and N3-offset, i.e., the first parameter, the second parameter, the third parameter, the first parameter, and the fifth parameter, may be configured by R.R.C.

According to further example embodiments, the value Nl is determined in implicit manner (i.e. may be dependent on) based on the configured reporting quantity (or metric). As an example, according to example embodiments, it is defined in a specification that a specific quantity such as R.SR.P is associated with a specific value for Nl, while another specific quantity such as signal to noise and interference ratio (SINR.) is associated with another specific value for Nl.

According to further example embodiments, the value Nl is selected by the terminal/UE (e.g. from a (radio resource control (R.R.C)) configured set of candidate values), wherein the Nl is indicated by the UL signal indicating the use of reporting occasion (i.e. reporting event has been triggered).

According to example embodiments, the value Nl indicates the reporting occasion the UE is configured to provision the event triggered report, which is explained above with respect to FIG. 10. Alternatively, according to example embodiments, the value N1 indicates the last reporting occasion the UE is configured to provision the event triggered report. This is illustrated in FIG. 11.

FIG. 11 shows a schematic diagram illustrating relationships between uplink resources and possible resource selection results according to example embodiments, and in particular illustrates exemplary associations of UL resources (reporting occasions) with an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event).

In particular, FIG. 11 schematically illustrates which UL resource (reporting occasion) 92c following an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a is the last UL resource (reporting occasion) associated with the UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a based on the value of the first parameter Nl.

Namely, as an example, with value Nl = 1, the last reporting occasion is the same as the first reporting occasion associated with the indication.

Further, as an example, with value Nl = 3 (as illustrated in FIG. 11), the last reporting occasion is the third reporting occasion associated with the indication. The UE may report in any of the valid reporting occasions before or including the last reporting occasion, e.g. Nl = 1 or Nl = 2 or Nl = 3.

Hence, as a generalized example, with value Nl = M, the last reporting occasion is the Mth reporting occasion associated with the indication. The UE may report in any of the valid reporting occasions before or including the last (Mth) reporting occasion. According to example embodiments, the value of N1 is expressed in symbols/slots subject to configured numerology with respect to the transmission occasion of UL signal/reference signal.

According to example embodiments, the value N1 is defined so that the default/first/first valid reporting occasions is the Nth reporting occasion.

According to example embodiments, the value N2, i.e., the second parameter, ranges from 1,2,3,4,...

According to further example embodiments, the value N2 configures the number of reporting occasions the UE is configured to report information once the reporting is triggered.

Namely, as an example, N2 = 1 means that the UE reports on the one associated reporting occasion.

Further, as an example, N2 = 2 means that the UE reports on the two (consecutive) occasions starting for the first associated reporting occasion.

According to further example embodiments, a specific one of the values of N2 is specified to configure the UE to report on reporting occasions (e.g. continuously) until the reporting is cancelled by the network using a downlink control signaling (e.g. DCI indication).

According to further example embodiments, the value N2 configures the number of reporting occasions associated with the reporting configuration so that up to N2 number of occasions correspond to the single reporting instance.

According to further example embodiments, the value of N3, i.e., the third parameter, has values e.g. 1,2,3,..., respectively defining repetition of triggered event reporting over N3 different transmission occasions. When the UE is configured with N3 = N2, according to example embodiments, the UE is indicated to repeat transmission of triggered event report over N2 consecutive reporting occasions.

According to further example embodiments, the UE may be configured additionally with higher layer parameter N3-non-consecutive, i.e., the fourth parameter, and N3-offset, i.e., the fifth parameter, where N3-non- consecutive is defined as a Boolean value with 'O=consecutive'/'l=non- consecutive' meaning, and the N3-offset indicates an offset between transmission occasions of event triggered reporting.

For example, when the UE is configured with N2=4, N3=2, N3-non- consecutive = 1, and N3-offset = 1, the UE shall repeat transmission of event triggered reporting over two non-consecutive transmission occasions of the report over N2 reporting occasions.

A result of such determination of UL resources is shown in FIG. 13. FIG. 13 shows a schematic diagram illustrating relationships between uplink resources and possible resource selection results according to example embodiments, and in particular illustrates exemplary associations of UL resources (reporting occasions) with an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event).

In particular, FIG. 13 schematically illustrates which UL resources (reporting occasion) 92a, 92c following an UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a are the UL resources (reporting occasions) associated with the UL signaling occasion (occasion for transmitting the notification, e.g. once reporting necessity is triggered by an event) 91a based on the values of the third to fifth parameters (N3 = 2, N3-non-consecutive = 1, and N3-offset = 1). According to further example embodiments, the combination of parameters N2 and N3, where N2>N3 and condition modulo(N2,N3) = 0 is fulfilled, implicitly indicates repetition of event triggered report over non-consecutive transmission occasions defined by N2. When the UE is not configured with parameter N3-offset, the UE shall assume offset to be 1. For example, when N2 = 4 and N3 = 2, the condition N2>N3 and modulo(4,2) = 0 is fulfilled, and thus the UE shall repeat transmission of event triggered reporting over two non-consecutive transmission occasions of the report over four reporting occasions.

According to further example embodiments, the terminal/UE performs measurements on at least one reference signal or a set of signals to determine if at least one reporting condition is fulfilled. Upon determining that the (at least one) reporting conditions is fulfilled, the terminal/UE determines to indicate the event (to network) by triggering a transmission of at least one indication/notifi cation.

According to further example embodiments, a reporting condition/event that may be evaluated by the UE may refer to one or more of following (but is not limited to these):

- first exemplary event: a quality (e.g. Ll-RSRP) of a reference signal is worse than a configured threshold;

- second exemplary event: a quality of at least one reference signal becomes a threshold value better than certain reference signal (such as reference signal corresponding to the PDCCH reception);

- third exemplary event: a quality of a reference signal is better than a certain threshold;

- fourth exemplary event: a quality of the certain reference signal is worse than a threshold 1, and quality of at least one reference signal is better than a (another) threshold 2.

According to further example embodiments, the terminal/UE, upon triggering the indication, further determines the timeline/time value associated with the triggered signal. The time value is determined based at least on one value configured in the triggered reporting (configuration), and the time value is calculated based on the periodic availability of the uplink reporting resource.

According to further example embodiments, the terminal/UE reports the event triggered report on the determined UL slot.

According to further example embodiments, the terminal/UE starts a timer that corresponds to the value determined by the UE upon triggering the UL signal.

According to further example embodiments, the terminal/UE, upon expiry of the timer, reports on the UL resource associated with the UL signal indicating the event.

According to further example embodiments, the timer length is configured such that it corresponds to the uplink slot in which the reporting is configured.

According to further example embodiments, the timer length is configured such that it corresponds to a slot Nx slot(s) prior to the uplink slot in which the reporting is configured, wherein upon expiry of the timer the terminal/UE prepares/computes/calculates the event triggered report.

According to further example embodiments, if the time interval between the UL signal and UL resource is less than X milliseconds/slots/symbols (i.e., a predetermined interval), the terminal/UE prepares the report upon triggering the UL signal.

According to further example embodiments, if the time interval between the UL signal and UL resource is less than X milliseconds/slots/symbols (i.e., a predetermined interval), the terminal/UE prepares the report prior to the triggering of the UL signal. As a result, according to example embodiments, advantageously, scheduling flexibility / configuration flexibility is enabled for the network, such that, consequently, waste of UL resources can be avoided, but also control/coordination signaling can be reduced.
