Abstract

Some embodiments of this disclosure include apparatuses and methods for sidelink procedures and structures for transmission and reception of non-standalone and standalone PSSCH in a wireless communication system.

First claim

What is claimed is:

1. A method, comprising:
selecting, by a user equipment (UE), a physical sidelink share channel (PSSCH) rate-matching (RM) mode from a plurality of PSSCH RM modes based on a scheduling decision and a congestion control function;
generating a sidelink control information (SCI) carrying a field indicating the selected PSSCH RM mode;
allocating, by the UE, in a lowest or a highest index sub-channel of a physical sidelink control channel (PSCCH) transmission, the SCI, wherein the allocating is based on the selected PSSCH RM mode to obtain no gaps between the PSCCH transmission and a PSSCH transmission; and
transmitting, by the UE, the SCI in the PSCCH transmission and symbols in the PSSCH transmission based on the selected PSSCH RM mode.

2. The method of claim 1 , wherein a PSSCH is formatted based on a quality of service (QoS) attribute level, including one or more of a priority, a reliability, a latency, a communication range, or a combination thereof.

3. The method of claim 1 , wherein the plurality of modes comprises four modes.

4. The method of claim 1 , wherein transmitting the symbols further comprising transmitting based on a sub-channelization procedure, wherein the sub-channelization procedure includes a sub-channel containing M contiguous PSCCH resources, where M may be a value greater than or equal to 1.

5. The method of claim 4 , further comprising configuring, by the UE, a sub-channel size associated with the sub-channel to utilize a spectrum in a subcarrier spacing (SCS) and a carrier bandwidth.

6. The method of claim 5 , further comprising deriving, by the UE, the sub-channel size from a number of sub-channels and a number of physical resource blocks (PRBs) in a vehicle-to-everything (V2X) resource pool.

7. The method of claim 5 , wherein the sub-channel size is equal to or greater than a number of the M contiguous PSCCH resources.

8. A non-transitory computer readable medium having instructions stored thereon that, when executed by a user equipment (UE), cause the UE to perform operations comprising:
selecting a physical sidelink shared channel (PSSCH) rate-matching (RM) mode from a plurality of PSSCH RM modes based on a scheduling decision and a congestion control function;
generating a sidelink control information (SCI) carrying a field indicating the selected PSSCH RM mode;
allocating in a lowest or a highest index sub-channel of a physical sidelink control channel (PSCCH) transmission, the SCI, wherein the allocating is based on the selected PSSCH RM mode to obtain no gaps between the PSCCH transmission and a PSSCH transmission; and
transmitting the SCI in the PSCCH transmission and symbols in the PSSCH transmission based on the selected PSSCH RM mode.

9. The non-transitory computer readable medium of claim 8 , wherein a PSSCH is formatted based on a quality of service (QoS) attribute level, including one or more of a priority, a reliability, a latency, a communication range, or a combination thereof.

10. The non-transitory computer readable medium of claim 8 , wherein the plurality of modes comprises four modes.

11. The non-transitory computer readable medium of claim 8 , wherein the operations further comprise transmitting the symbols based on a sub-channelization procedure, wherein the sub-channelization procedure includes a sub-channel containing M contiguous PSCCH resources, where M may be a value greater than or equal to 1.

12. The non-transitory computer readable medium of claim 11 , wherein the operations further comprise configuring a sub-channel size associated with the sub-channel to utilize a spectrum in a subcarrier spacing (SCS) and a carrier bandwidth.

13. The non-transitory computer readable medium of claim 12 , wherein the operations further comprise deriving the sub-channel size from a number of sub-channels and a number of physical resource blocks (PRBs) in a vehicle-to-everything (V2X) resource pool.

14. The non-transitory computer readable medium of claim 12 , wherein the sub-channel size is equal to or greater than a number of the M contiguous PSCCH resources.

15. A user equipment (UE) comprising:
a processor configured to:
select a physical sidelink shared channel (PSSCH) rate-matching (RM) mode from a plurality of PSSCH RM modes based on a scheduling decision and a congestion control function;
generate a sidelink control information (SCI) carrying a field indicating the selected PSSCH RM mode;
allocate in a lowest or a highest index sub-channel of a physical sidelink control channel (PSCCH) transmission, the SCI, wherein the allocating is based on the selected PSSCH RM mode to obtain no gaps between the PSCCH transmission and a PSSCH transmission; and
a radio frequency integrated circuit, coupled to the processor, configured to: transmit the SCI in the PSCCH transmission and symbols in the PSSCH transmission based on the selected PSSCH RM mode.

16. The UE of claim 15 , wherein a PSSCH is formatted based on a quality of service (QoS) attribute level, including one or more of a priority, a reliability, a latency, a communication range, or a combination thereof.

17. The UE of claim 15 , wherein the plurality of modes comprises four modes.

18. The UE of claim 15 , wherein the radio frequency integrated circuit is further configured to transmit the symbols based on a sub-channelization procedure, wherein the sub-channelization procedure includes a sub-channel containing M contiguous PSCCH resources, where M may be a value greater than or equal to 1.

19. The UE of claim 18 , wherein the processor is further configured to configure a sub-channel size associated with the sub-channel to utilize a spectrum in a subcarrier spacing (SCS) and a carrier bandwidth.

20. The UE of claim 19 , wherein the processor is further configured to derive the sub-channel size from a number of sub-channels and a number of physical resource blocks (PRBs) in a vehicle-to-everything (V2X) resource pool.
