- CSI-RS reference signals are UE-specifically configured in RRC. However, CSI-RS reference signals can be shared among many UEs, i.e., more than 1 UE are configured to receive the same resource elements (RE).
- RE resource elements
- the gNB would try to use cellspecific or group-specific CSI-RS resources.
- the worst case of DL overhead is with UE specific CSI-RS where the DL overhead increases linearly with the number of UEs in the cell.
- CSI-RS has many functions in NR, for example it may include:
- CSI-RS for beam management (BM) (based on Ll-RSRP);
- CSI-RS are spatially beamformed into different directions.
- a UE can be configured with up to 48 report configurations (CSI- ReportConfig) per component carrier (CC) / 4 per bandwidth part (BWP)
- CSI- ReportConfig per component carrier
- BWP bandwidth part
- One CSI resource config within 1 report configuration can be configured with up to 16 resource sets (aperiodic CSI) and 1 resource set (otherwise).
- each CSI resource set up to 64 NZP CSI-RS resources and 1 NZP-CSI- RS resource up to 32 antenna ports.
- the UE is configured also with a codebook type. Given the measured channel across a CSI-RS resource, the UE can choose a favourite codeword from the specified codebook, i.e., precoding matrix indicator (PMI), along with channel quality indicator (CQI), rank indicator (RI). UE can also be configured to measure several CSI-RS resources (up to 8) within a resource set and report the favourite resource, CSI-RS resource indicator (CRI), along with PMI, CQI and RI which corresponds to that selected resource.
- PMI precoding matrix indicator
- CQI channel quality indicator
- RI rank indicator
- UE can also be configured to measure several CSI-RS resources (up to 8) within a resource set and report the favourite resource, CSI-RS resource indicator (CRI), along with PMI, CQI and RI which corresponds to that selected resource.
- CRI channel quality indicator
- a CSI-RS resource may start at any OFDM symbol of a slot and it spans 1, 2, or 4 OFDM symbols depending on the number of ports configured.
- the UE measurement reporting of CSI can be also operated with periodic, semi-persistent, or aperiodic manner, which is so-called report types in NR report configuration.
- the UE periodic report can operate only based on the configured periodic CSI-RS resource-set
- the UE semi-persistent report can operate based on both configured periodic and semi- persistent CSI-RS resource-set
- the UE aperiodic report can operate based on all periodic, semi-persistent, and aperiodic CSI-RS resource-set.
- the periodic CSI-RS resources can be used to generate any report type
- the semi-persistent and periodic CSI-RS resources can be used to generate semi- persistent CSI reports
- the aperiodic CSI-RS can only be utilized only to generate the aperiodic report.
- the CSI Report Setting also defines which part of the bandwidth the CSI should correspond to, and in addition, what granularity in frequency the CSI should have. To accomplish this, the bandwidth of a BWP is divided into a number of subbands. [0089] All CSI-RS resources within one set are configured with same density and same nrofPorts, where NrofPorts define a number of CSI-RS port(s). Except for the NZP CSI-RS resources used for interference measurement.
- the actual triggering of CSI-RS transmission is per CSI-RS resource-set via either MAC CE or DCI.
- a resource set can be used as part of UE report configurations describing what to be measured and, correspondingly, which measurement reporting are to be done by the UE.
- the CSI-RS resource set configuration includes a slot offset, a periodicTriggeringOffset which defines the time interval between the triggering DCI and the CSI-RS transmission.
- A-CSI reporting up to 16 different reporting settings can be triggered with single DCI (e.g. for multiple component carriers) while SP-CSI reporting can trigger only one report setting with a single DCI. In order to trigger several SP-CSI reports (each in different slots), multiple DCIs are needed.
- Rell7 introduced a unified TCI framework meaning that TCI states so far providing QCL assumptions for the reception of DL signals and channels would be used also to provide spatial sources for the transmission of UL signals and channels to determine UL TX spatial filter.
- the unified TCI framework defines the concept of indicated TCI state. That means that one or multiple (in case of multi-TRP for instance) of the configured TCI states is/are indicated TCI state(s) at a time.
- the indicated TCI state can be joint DL and UL TCI state or separate DL and separate UL TCI states.
- Indicated TCI state provides QCL source (DL) and spatial source (UL) for the set of downlink signals and channels and for the set of uplink signals and channels, respectively.
- Rell7 there can be one indicated joint DL and UL or one indicated DL and one indicate UL TCI state for the UE.
- Unified TCI framework is expected to be extended in Rell8 so that there can be then multiple indicated DL and UL TCI states.
- Standards at the time of this application provide support for both UE nongroup and group-based beam reporting schemes.
- the network can configure up to four CRIs / beams with Ll-RSRP values to be reported (via PUCCH or PUSCH).
- UE-initiated or event-based CSI reporting and/or beam switch is a strong candidate for discussions regarding standards at the time of this application.
