Abstract: Methods and apparatuses for contention window adjustment on a sidelink (SL) in a wireless communication system. A method of a user equipment (UE) includes determining whether hybrid automatic repeat request (HARQ) feedback is available after a last update of a contention window size (CW); determining a set of HARQ feedback corresponding to physical sidelink shared channels (PSSCHs) in a reference duration when the at least one HARQ feedback is determined as available; and determining a first condition based on the set of HARQ feedback. The method further includes determining to: reset the CW to a minimum allowed value when the first condition is satisfied or increase the CW to a next higher allowed value when the first condition is not. The method further includes performing a SL channel access procedure based on the CW and performing a SL transmission over a channel after successfully performing the SL channel access procedure.

Abstract: Methods and apparatuses for frequency domain enhancement on physical sidelink feedback channel (PSFCH) in a wireless communication system. A method of operating user equipment (UE) includes receiving a physical sidelink shared channel (PSSCH) that enables a hybrid automatic repeat request (HARQ) feedback and determining an interlace from a set of interlaces. Each interlace in the set of interlaces includes a first set of resource blocks (RBs) with a uniform interval. The method further includes determining a RB set with contiguous RBs, determining, based on an intersection between the interlace and the RB set, a second set of RBs for a physical sidelink feedback channel (PSFCH) transmission, performing a sidelink (SL) channel access procedure and transmitting, after successfully performing the SL channel access procedure, the PSFCH carrying the HARQ feedback in the second set of RBs.

Abstract: Apparatuses and methods for channel state information (CSI) measurement and report outside an active downlink (DL) bandwidth part (BWP). A method for a user equipment includes receiving configurations for a first set of DL BWPs, for reference signal (RS) resource sets in a second set of DL BWPs, and for CSI reports corresponding to the second set of DL BWPs; receiving RS resources from the RS resource sets in a third set of DL BWPs; and determining a first number of CSI reports based on the received RS resources. The method further includes determining a second number of CSI reports that have (i) values for a CSI report quantity that are larger those in other CSI reports from the first number of CSI reports and (ii) corresponding DL BWP indexes and transmitting a channel that includes the second number of CSI reports and the indexes.

Abstract: Apparatuses and methods for power control for data and control channels. A method of operating a user equipment includes receiving information for a first transmission occasion for a physical uplink shared channel (PUSCH) and a second transmission occasion for a second physical uplink control channel (PUCCH) and receiving a first transmit power control (TPC) command. The method further includes determining a first power control adjustment state based on the first TPC command and a second power control adjustment state based on the first power control adjustment state. The method further includes transmitting the PUSCH in the first transmission occasion using the first power and the PUCCH in the second transmission occasion using the second power.

Abstract: Apparatuses and methods for spatial setting determination based on synchronization signals and physical broadcast channel (SS/PBCH) block receptions. A method performed by a user equipment (UE) in a wireless communication system includes receiving first information for a first set of indexes for synchronization signals and physical broadcast channel (SS/PBCH) blocks, a first SS/PBCH block corresponding to a first index from the first set of indexes, second information for a second set of indexes for SS/PBCH blocks, and a second SS/PBCH block corresponding to a second index from the second set of indexes. The method further includes determining a physical cell identity (PCI) of a serving cell based on the first SS/PBCH block and a path-loss based on the second SS/PBCH block. The first SS/PBCH block and the second SS/PBCH block have a same transmission power.

Abstract: Methods and apparatuses for coverage enhancement of Msg3. A method for operating a user equipment includes receiving a system information block (SIB) that provides information mapping physical random access channel (PRACH) resources to enable or disable repetitions for a physical uplink shared channel (PUSCH) transmission in a random access procedure and a first time domain resource allocation (TDRA) table. An entry of the first TDRA table indicates a number of repetitions of a PUSCH transmission. The method further includes determining a PRACH resource for transmission of a PRACH, determining, based on the PRACH resource, a TDRA table from between the first TDRA table or a predetermined second TDRA table. No entry of the second TDRA table indicates a number of repetitions for a PUSCH transmission. The method further includes receiving a first grant scheduling transmission of a first PUSCH and transmitting the first PUSCH.
