- Hybrid automatic retransmission Hybrid Automatic Repeat Request, HARQ
- the control node and the UE communicate through the Uu interface and use the uplink and downlink (ie Uplink and Downlink), and the UE and the UE use the PC5 interface and use the side link (ie Sidelink, also called For direct link, secondary link, side link or side link, etc.) communication, as shown in Figure 1a.
- uplink and downlink ie Uplink and Downlink
- side link ie Sidelink, also called For direct link, secondary link, side link or side link, etc.
- the UE can use the physical uplink control channel (PUCCH) or the physical uplink shared channel (Physical Uplink Control Channel, PUCCH) according to its own reception and decoding status.
- the HARQ-ACK information ie, NACK or ACK
- PUSCH Uplink Shared Channel
- the UE sends sidelink control information (Sidelink Control Information, SCI) through the Physical Sidelink Control Channel (PSCCH), and schedules the physical sidelink shared channel (PSSCH). Transmit to send Sidelink data.
- SCI Sidelink Control Information
- PSCCH Physical Sidelink Control Channel
- PSSCH physical sidelink shared channel
- the HARQ feedback mechanism is also introduced in NR Sidelink technology: After Sidelink receives the Sidelink data, the UE can feed back the Sidelink HARQ-ACK information to indicate the success or failure of the Sidelink transmission , The HARQ response is sent through the Physical Sidelink Feedback Channel (PSFCH).
- PSFCH Physical Sidelink Feedback Channel
- Sidelink transmission may not be carried out between the control node and the UE, but on the Sidelink between the UE and the UE, as shown in Figure 1c. Therefore, the control node cannot directly know whether the transmission of the Sidelink data packet is successful, and the UE needs to send the Sidelink HARQ-ACK information to the control node, so that the control node can further determine whether the transmission on the Sidelink is successful, and finally determine whether the next step is
- the sending UE needs to be scheduled to retransmit on Sidelink.
- the UE that reports the Sidelink information may be a sending UE or a receiving UE.
- the so-called sending UE and receiving UE refer to the UE that sends and receives the Sidelink transmission corresponding to the Sidelink information. It should be noted that a Sidelink UE may be a sending or receiving UE. For example, the UE sends Sidelink data at time a1, and receives Sidelink data from other UEs at time a2.
- FIG. 1d An example of sending the UE to report the Sidelink HARQ-ACK information to the control node can be shown in Figure 1d.
- the control node schedules UE1 to send a transport block (Transport Block, TB) to UE2 on Sidelink.
- UE2 receives the TB but cannot successfully solve it, so it feeds back a NACK on the PSFCH.
- UE1 maps the Sidelink NACK to Uu NACK and sends it to the control node on the target resource.
- the control node After receiving the NACK, the control node knows that the transmission of the TB has failed, and therefore sends a scheduling signaling to schedule UE1 to retransmit the TB on Sidelink.
- FIG. 1e An example of receiving UE reporting Sidelink HARQ-ACK information to the control node can be shown in Figure 1e.
- the Sidelink receiving UE determines the Sidelink HARQ-ACK information according to the received Sidelink transmission and decoding, if there is a Uu connection between the Sidelink receiving UE and the control node and the corresponding target resource is allocated, the Sidelink HARQ can be directly assigned to the target resource.
- the ACK information is sent to the control node, and may not be sent to the sending UE through the PSFCH at this time.
- UE2 transmits NACK to UE1 and adds square brackets to indicate that this step may or may not exist.
- ⁇ resource allocation modes There are two resource allocation modes in Sidelink, namely, scheduled resource allocation (ie, Scheduled Resource Allocation) mode and autonomous resource selection (ie, Autonomous Resource Selection) mode.
- scheduled resource allocation ie, Scheduled Resource Allocation
- autonomous resource selection ie, Autonomous Resource Selection
- the former is controlled by the control node and allocates resources for each UE, and the latter is independently selected by the UE.
- two resource allocation modes may also be performed at the same time.
- control node can be a base station, an integrated access backhaul node (Integrated Access Backhaul, IAB), user equipment, relay equipment (i.e. Relay) or road side unit (Road Side Unit, RSU), etc., or some Other network facilities similar to RSU or IAB.
- IAB integrated access backhaul node
- Relay relay equipment
- RSU road side unit
- control nodes can support Sidelink and Uu links at the same time.
- Uplink Control Information (UCI) information :
- the uplink control information fed back by the UE is collectively referred to as UCI.
- UCI An important part of UCI is HARQ-ACK information.
- the above UCI can also include channel state information ( Channel State InFormation (CSI) report, scheduling request (Scheduling, SR), etc.
- CSI Channel State InFormation
- SR scheduling request
- UCI can be transmitted on PUCCH resources or PUSCH resources, where PUCCH resources can support 5 formats (ie Format), and different formats have different characteristics.
- PUCCH Format0 carries 1 or 2 bits UCI in the form of a sequence, the time domain occupies 1 or 2 symbols, and the frequency domain occupies 1 resource block (Resource Block, RB).
- the HARQ-ACK information transmitted by Sidelink can be transmitted on the PSFCH channel, and the CSI transmitted by Sidelink can be transmitted on the PSSCH.
- PSFCH currently supports the PUCCH Format 0 sequence basis (but the amount of time-frequency domain resources that may be occupied is different, Or introduce other new features, or introduce other new Format), so it can be called PSFCH Format0. It should be noted that this is not limited to PSFCH Format0, and can also be called other names according to actual conditions.
- the HARQ-ACK information of the uplink information transmitted on the uplink can be called Uu HARQ-ACK information
- the HARQ-ACK information transmitted on the Sidelink can be called Sidelink HARQ-ACK. information.
- the HARQ-ACK information corresponding to a TB is 1 bit. If the bit is 1, it means ACK, and if it is 0, it means NACK. If the control node sends multiple TBs, and the control node instructs the UE to send the HARQ-ACK information corresponding to these TBs to the control node on the same resource, the UE can transfer these TBs in a manner (such as a codebook) specified by the protocol.
- the HARQ-ACK information is multiplexed into a new HARQ-ACK information (for example, a bitmap (ie, Bitmap)), and reported to the control node.
- the control node sends 3 TBs, where TB#1 and TB#3 are successfully decoded by the UE, and TB#2 fails to decode, the value of the HARQ-ACK information bits corresponding to the 3 TBs They are 1, 1 and 0, which represent ACK, ACK, and NACK, respectively.
- the control node instructs the UE to send the HARQ-ACK information bits corresponding to these 3 TBs on the same PUCCH, and the UE multiplexes the 3 HARQ-ACK information bits into a Bitmap 101 and sends it to the control node.
- NR supports two uplink semi-persistent scheduling grant uplink transmission (i.e. Configured UL Grant) methods: the first type (i.e. Type 1) and the second type (i.e. Type 2).
- Configured UL Grant Type1 resources can be semi-statically configured through radio resource control (Radio Resource Control, RRC) signaling. After receiving the configuration, the user equipment can use the configuration according to its own service arrival and configuration conditions For transmission, there is no need for Downlink Control Information (DCI) for dynamic scheduling.
- RRC Radio Resource Control
- Configured UL Grant Type 2 resources can be semi-statically configured through RRC signaling, and the user equipment cannot directly use the configuration after receiving the configuration. After the control node further activates the configuration through DCI, the user equipment can activate DCI according to the configuration Use this authorized resource. The control node may also deactivate the configuration through DCI, and the user equipment that receives the deactivated DCI will stop the authorized resource.
- a Configured UL Grant usually corresponds to periodic resources that can be used for the UE to send signals, and each period includes multiple transmission opportunities (ie, Transmission Occasion). Compared with conventional dynamic scheduling (ie, Dynamic Grant), Configured UL Grant can reduce signaling overhead and interaction procedures, and ensure low latency requirements.
- the control node configures Sidelink resources without additional signaling for activation and/or deactivation.
- the configured user equipment can use these resources according to the incoming packet status.
- This resource configuration can be but not limited to being called Configured Sidelink Grant Type1.
- Control node signaling configures Sidelink resources, and additional signaling is needed to activate and/or deactivate the resources.
- This resource configuration can be, but is not limited to, called Configured Sidelink Grant Type 2.
- control node can configure multiple Configured Sidelink Grants for the user equipment.
