Operating method of UE related to SCI transmission in wireless communication system
In one embodiment is an operating method of user equipment (UE) in a wireless communication system, comprising the steps of: transmitting a first sidelink control channel (SCI) on a physical sidelink control channel (PSCCH); and transmitting a second SCI on a physical sidelink shared channel (PSSCH), wherein the modulation order of a second stage SCI is used in determining the number of symbols for transmission of the second stage SCI.
1. An operation method of a user equipment (UE) in a wireless communication system, the method comprising:
transmitting 1st stage Sidelink Control Information (SCI) on a physical sidelink control channel (PSCCH); and
transmitting 2nd stage SCI on a physical sidelink shared channel (PSSCH),
wherein a number of symbols for transmission of the 2nd stage SCI is determined based on a multiplication of (i) a number of 2nd stage SCI-related bits and (ii) a reciprocal of a modulation order of the 2nd stage SCI.
2. The method of claim 1 , wherein the number of the 2nd stage SCI-related bits includes a cyclic redundancy check (CRC) of the 2nd stage SCI.
3. The method of claim 2 , wherein the CRC corresponds to 24 bits.
4. The method of claim 1 , wherein the modulation order of the 2nd stage SCI is different from a modulation order of the PSSCH.
5. A user equipment (UE) in a wireless communication system, comprising:
at least one processor; and
at least one computer memory operably coupled to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations,
wherein the operations comprises:
transmitting 1st stage Sidelink Control Information (SCI) on a physical sidelink control channel (PSCCH); and
transmitting 2nd stage SCI on a physical sidelink shared channel (PSSCH),
wherein a number of symbols for transmission of the 2nd stage SCI is determined based on a multiplication of (i) a number of 2nd stage SCI-related bits and (ii) a reciprocal of a modulation order of the 2nd stage SCI.
6. The UE of claim 5 , wherein the number of the 2nd stage SCI-related bits includes a cyclic redundancy check (CRC) of the 2nd stage SCI.
7. The UE of claim 6 , wherein the CRC corresponds to 24 bits.
8. The UE of claim 5 , wherein the modulation order of the 2nd stage SCI is different from a modulation order of the PSSCH.
9. A processor for performing operations for a user equipment (UE) in a wireless communication system,
wherein the operations comprises:
transmitting 1st stage Sidelink Control Information (SCI) on a physical sidelink control channel (PSCCH); and
transmitting 2nd stage SCI on a physical sidelink shared channel (PSSCH),
wherein a number of symbols for transmission of the 2nd stage SCI is determined based on a multiplication of (i) a number of 2nd stage SCI-related bits and (ii) a reciprocal of a modulation order of the 2nd stage SCI.
10. A non-volatile non-transitory computer-readable storage medium storing at least one computer program including instructions that, when executed by at least one processor, cause the at least one processor to perform operations for a user equipment (UE),
wherein the operations comprises:
transmitting 1 st stage Sidelink Control Information (SCI) on a physical sidelink control channel (PSCCH); and
transmitting 2nd stage SCI on a physical sidelink shared channel (PSSCH),
wherein a number of symbols for transmission of the 2nd stage SCI is determined based on a multiplication of (i) a number of 2nd stage SCI-related bits and (ii) a reciprocal of a modulation order of the 2nd stage SCI.
