Assignee: LG ELECTRONICS INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 13:
14. A first device configured to perform wireless communication, the first device comprising:
one or more memories storing instructions;
one or more transceivers; and
one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
receive at least one physical sidelink control channel (PSCCH);
receive at least one physical sidelink shared channel (PSSCH) related to the at least one PSCCH;
determine a resource related to at least one physical sidelink feedback channel (PSFCH) based on an index of a slot and an index of a subchannel related to the at least one PSSCH;
determine N PSFCHs from among the at least one PSFCH based on a sum of power required to transmit the at least one PSFCH being greater than a maximum transmit power of the first device,
wherein N is an integer that satisfies N1<N<NMAX, where N1 denotes a number of PSFCH transmissions with priorities higher than or equal to a priority, and NMAX denotes a maximum number of PSFCH transmissions of the first device, and
wherein the priority is determined such that a total transmit power related to the PSFCH transmissions with priorities higher than or equal to the priority does not exceed the maximum transmit power of the first device;
determine a transmit power for the N PSFCHs; and
transmit the N PSFCHs based on the transmit power.
