    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: Methods and apparatuses a joint operation of conditional handover and conditional PSCell addition or change in a wireless communication system. A method of a UE comprises: receiving information including association information, execution conditions, and configurations for candidate PCells and candidate PSCells; evaluating the execution conditions for the candidate PCells and associated candidate PSCells simultaneously; upon the execution conditions for (i) a candidate PCell among the candidate PCells and (ii) a candidate PSCell associated with the candidate PCell are satisfied, determining that the candidate PCell and the associated candidate PSCell as a target PCell and an associated target PSCell, respectively; applying the configurations for the target PCell and the associated target PSCell; performing a random access procedure for the target PCell; and performing a random access procedure for the associated target PSCell.

    Abstract: Methods and apparatuses in a wireless communication system. A method of operating a first user equipment (UE) comprises: receiving, from a second UE, inter-UE coordination information including sidelink (SL) resources and a zone identification (ID) for resource allocation for transmission of SL data; identifying a transmission range for the transmission of the SL data; calculating, based on the zone ID, a distance between the second UE and the first UE; determining whether the inter-UE coordination information is valid based on the transmission range and the distance; identifying the SL resources based on a determination that the inter-UE coordination information is valid; and transmitting the SL data.

    Abstract: Methods and apparatuses for sidelink (SL) network assisted inter-user equipment (UE) coordination in a wireless communication system. A method for operating a UE includes receiving, on a Uu interface, a message associated with SL inter-UE coordination information, determining SL resources for a SL transmission based on the SL inter-UE coordination information, selecting the SL resources for the SL transmission, and transmitting on a SL interface using the SL resources. A method of operating a BS includes receiving, on a Uu interface, a message including first SL inter-UE coordination information from a first UE, determining a second UE as a recipient for the first SL inter-UE coordination information, generating second SL inter-UE coordination information from aggregation of the first SL inter-UE coordination information and other SL inter-UE coordination information, and transmitting the second SL inter-UE coordination information to the second UE.
