- 6G 6th Generation
- NR SL resource allocation There are two ways of NR SL resource allocation, one is based on base station scheduling (mode 1 (mode 1)), and the other is based on terminal (for example, user equipment (User Equipment, UE)) autonomous resource selection (mode 2) .
- mode 1 base station scheduling
- UE user equipment
- TX Transmission
- UE User Equipment
- mode 2 autonomous resource selection
- the resource allocation method scheduled by the base station the sidelink resources used by the UE for data transmission are determined by the base station, and the transmission (Transmission, TX) UE is notified through downlink signaling; for the resource allocation method independently selected by the UE, the UE is in the (pre) configured
- the available transmission resources are selected from the resource pool, and the UE performs channel monitoring before resource selection, selects a resource set with less interference according to the channel sensing (sensing) result, and then randomly selects resources for transmission from the resource set.
- the TX UE After the resource selection is triggered, the TX UE first determines the resource selection window. The lower boundary of the resource selection window is T1 after the resource selection is triggered, and the upper boundary of the resource selection is T2 after the trigger, where T2 is implemented by the UE.
- T2 is implemented by the UE
- the value selected by the mode in the Packet Delay Budget (PDB) transmitted by its Transport Block (TB), T2 is not earlier than T1.
- PDB Packet Delay Budget
- TB Transport Block
- the UE Before resource selection, the UE needs to determine the candidate resource set (candidate resource set) for resource selection, according to the reference signal receiving power (Reference Signal Receiving Power, RSRP) measured on the resource within the resource selection window and the corresponding RSRP
- the threshold (threshold) is compared, if the RSRP is higher than the RSRP threshold, then the resource is excluded and cannot be included in the candidate resource set. After resource exclusion, the remaining resources in the resource selection window form the candidate resource set.
- the resources in the candidate resource set account for no less than 20% of the resources in the resource selection window. If it is less than 20%, the RSRP threshold needs to be increased according to the step value (3dB), and then the resource exclusion operation is performed , until not less than said 20% of resources can be selected.
- the UE After the candidate resource set is determined, the UE randomly selects a transmission resource from the candidate resource set. In addition, the UE may reserve transmission resources for the next transmission in this transmission.
- Periodic part detection is applicable to the situation where periodic resource reservation is enabled in the resource pool.
- the UE When the UE performs resource selection, it needs to determine Y candidate time slots in the resource selection window (the minimum value of Y is configured/preconfigured), and each time slot in the Y candidate time slots should be periodic monitoring results.
- Y candidate time slots the minimum value of Y is configured/preconfigured
- each time slot in the Y candidate time slots should be periodic monitoring results.
- the time slots that the UE needs to monitor are as follows:
- Preserve is a period value
- Preserve is one or more configured values
- each period value k corresponds to one or more integer values.
- the UE When the UE performs resource selection, it needs to perform continuous channel monitoring before determining the set of candidate resources.
- the size of the monitoring window is determined by the Tracking Area (TA) and TB.
- the continuous part detection mechanism also involves the location of resource selection.
- the resource selection window can appear after the continuous detection window, and resource selection will be performed in the selection window; or, the candidate time slot appears after the continuous detection window, and resource selection will be performed on alternate time slots. It can be understood that no matter whether the position of resource selection is named as resource selection window or candidate time slot, it is to limit the time position where resource selection can occur, and there is no essential difference.
