Abstract: Methods and apparatuses for initiating channel occupancy in a semi-static mode SL channel access in a wireless communication system. A method of a user equipment (UE) includes receiving, from a higher layer, an indication on a semi-static mode SL channel access, receiving a set of configurations for the semi-static mode SL channel access, including a duration of a period and determining a first portion of the period as a channel occupancy associated with the period. The method further includes determining a second portion of the period as an idle duration associated with the period, performing a SL channel access procedure in the idle duration associated with the period, and transmitting a first SL transmission over a channel in the channel occupancy associated with the period after successfully performing the SL channel access procedure.

Abstract: Apparatuses and methods for time domain resource allocation for a physical sidelink feedback channel (PSFCH) with carrier aggregation are provided. A method of a user equipment (UE) includes receiving a set of configurations from a higher layer and a carrier indicator field in a physical channel. The method further includes identifying, based on the set of configurations, a resource pool including resource blocks (RBs) for transmission of PSFCHs; identifying, based on the set of configurations, a first carrier frequency from a set of carrier frequencies based on the carrier indicator field; and determining a first set of RBs from the resource pool for transmission of a first PSFCH in the first carrier frequency. The method further includes determining a first transmission occasion for the first PSFCH and transmitting the first PSFCH in the first transmission occasion using the first set of RBs in the first carrier frequency.

Abstract: Apparatuses and methods for transmission window determination for a physical sidelink feedback channel (PSFCH) in a wireless communication system. A method of user equipment (UE) includes receiving a set of configurations from a higher layer and receiving a physical sidelink shared channel (PSSCH). The PSSCH enables hybrid automatic repeat request (HARQ) feedback. The method further includes determining a transmission window for a PSFCH; performing a sidelink (SL) channel access procedure before a transmission occasion in the one or multiple transmission occasions; and transmitting the HARQ feedback in the transmission occasion for the PSFCH over a channel upon successfully performing the SL channel access procedure. The transmission window includes the one or multiple transmission occasions for the PSFCH and the one or multiple transmission occasions are based on at least one of: a window offset, an interval between two neighboring transmission occasions, and a number of transmission occasions.

Abstract: Methods and apparatuses for channel occupancy indication on a sidelink (SL) in a wireless communication system. A method of operating user equipment (UE) includes receiving a SL control information (SCI) format over a sidelink channel; determining, from the SCI format, at least one of: time domain information for a channel occupancy, frequency domain information for the channel occupancy, and a SL channel access procedure. The method further includes performing the SL channel access procedure before a sidelink transmission; and transmitting, upon successfully performing the sidelink channel access procedure, the SL transmission over the SL channel within the channel occupancy based on the time domain information or the frequency domain information for the channel occupancy.

Abstract: Methods and apparatuses for random access procedures in a wireless communication system. A method for operating a user equipment (UE) includes receiving a system information block (SIB) in a downlink bandwidth (DL) part (BWP). The DL BWP is linked to a first uplink (UL) BWP. The SIB includes an indication for one or more UL BWPs. The method further includes transmitting a physical random access channel (PRACH) in a second UL BWP from the one or more UL BWPs. The second UL BWP is different than the first UL BWP.

Abstract: Methods and apparatuses for switching duplex mode during random access (RA). A method for operating a user equipment (UE) includes receiving a system information block (SIB) for a cell that provides information for a first configuration of slots for transmissions or receptions in a half-duplex mode and a random access (RA) procedure, determining a UE capability for transmitting and receiving in a full-duplex mode, and determining a transmission of a channel based on the RA procedure and the first configuration of slots. The method further includes transmitting the channel including information of the UE capability using the RA procedure and receiving information for a second configuration of slots for transmissions or receptions in the full-duplex mode.

Abstract: Apparatuses and methods for transmission of physical sidelink feedback channels (PSFCHs). A method performed by a user equipment (UE) in a wireless communication system includes receiving first information related to a sidelink operation on multiple sidelink carriers and receiving, via a sidelink control information (SCI) format, second information related to a first carrier from the multiple sidelink carriers for transmission of a PSFCH. The PSFCH includes hybrid automatic repeat request acknowledgement (HARQ-ACK) information corresponding to reception of a physical sidelink shared channel (PSSCH). Reception of a physical sidelink control channel (PSCCH) associated with the PSSCH is on a second carrier. The method further includes determining a resource for transmission of the PSFCH on the first carrier from a sidelink resource pool of PSFCH resources associated with the first carrier and transmitting the PSFCH on the first carrier using the resource.
