- NR V2X in addition to the HARQ (Hybrid Automatic Repeat Request) retransmission initiated by the UE without feedback, NR V2X introduces feedback-based HARQ retransmission, which is not limited to unicast communication, but also Including multicast communication.
- HARQ Hybrid Automatic Repeat Request
- NR V2X In NR V2X, some new features have been introduced, such as support for a large number of aperiodic services, an increase in the number of retransmissions, and a more flexible resource reservation period. All of these features have a great influence on the mode of the UE's autonomous resource selection. Therefore, based on Mode B in LTE V2X, 3GPP re-discussed and designed a resource selection scheme suitable for NR V2X, denoted as Mode 2. In mode 2, the UE selects the resource pool that is not reserved by other UEs or reserved by other UEs but has a lower received power by decoding the SCI (Sidelink Control Information, sideline control information) sent by other UEs and measuring the SL received power. low transmission resources.
- SCI Segment Control Information, sideline control information
- the resource selection scheme of mode 2 in NR V2X is divided into two main steps, that is, the UE first determines the candidate resource set, and then selects transmission resources from the candidate resource set to send
- Step 1 The UE determines the candidate resource set [38.214].
- the UE takes all available transmission resources in the resource selection window as resource set A. First, the UE needs to determine whether the transmission resource is reserved by other UEs according to the listening result in the resource listening window. Then, the UE performs resource exclusion according to the unlistened time slot and the sensed first-order SCI. After completing resource exclusion, if the number of remaining transmission resources in resource set A is less than a certain percentage, the UE will increase the RSRP (Reference Signal Receiving Power, reference signal receiving power) threshold by 3dB, and repeat resource exclusion until the remaining number of resources in resource set A The number of transmission resources is greater than or equal to this ratio.
- RSRP Reference Signal Receiving Power, reference signal receiving power
- the value of this ratio in NR V2X is more flexible, and its possible values are ⁇ 20, 35, 50 ⁇ %, and the specific ratio is based on the resource pool. Units are configured or preconfigured by the network. Finally, the resource set A after resource exclusion is the candidate resource set of the UE.
- Step 2 The UE selects the transmission resource in the candidate resource set [38.321].
- the UE randomly selects one or more transmission resources in the resource set A with moderate probability. It should be pointed out that the following time domain restrictions must be satisfied when selecting the multiple transmission resources:
- the UE shall enable a certain selected retransmission transmission resource to be indicated by the previously sent first-order SCI.
- the above exceptions include: after the UE performs resource exclusion, the UE cannot select a transmission resource that satisfies the time domain restriction from the resource set A.
- the above exceptions also include: due to factors such as resource preemption, congestion control, and conflict with uplink services, the UE abandons transmission, so that the transmission resources of a certain retransmission are not indicated by the previously sent first-order SCI.
- the UE shall guarantee any two selected transmission resources. If the previous transmission resource requires HARQ feedback, the two transmission resources shall be separated by at least Z in the time domain (Z is a positive number).
- Z is a positive number.
- the resource selection cannot meet the time domain restriction, for example, when the PDB (Physical Data Block) is short but the number of retransmissions is large, depending on the UE implementation, the selection of some retransmission resources can be abandoned or the selection of certain retransmission resources can be given up.
- Several transmissions deactivate HARQ feedback.
- the SL transmission includes periodic transmission
- the sender UE indicates a 4-bit (bit) reservation period value in the sent SCI to inform other UEs that the sender UE periodically reserves transmission resources for communicating data transmission.
