Abstract: Methods and apparatuses for orthogonal frequency division multiplexing (OFDM) symbol adjustment for sidelink (SL) transmissions in a wireless communication system. A method of user equipment (UE) includes receiving a sidelink control information (SCI) format that includes information on a cyclic prefix (CP) extension, determining parameters (Ci and Δi) based on the information on the CP extension, and determining a duration for the CP extension based on the parameters. The method further includes extending a sidelink OFDM symbol for an interval preceding the sidelink OFDM symbol for the duration for the CP extension and transmitting the sidelink OFDM symbol with the extended CP duration.

Abstract: Methods and apparatuses for random access (RA) in full-duplex (FD) wireless communication systems. A method for transmitting a random access channel (RACH) associated with a RA procedure includes receiving first information for first parameters of a first RACH configuration associated with a first subset of slots from a set of slots on a cell, second information for second parameters of a second RACH configuration associated with a second subset of slots from the set of slots on the cell, and third information for a condition. The method further includes determining whether the condition is valid for transmission in a slot from the second subset of slots and transmitting a RACH in the slot based on: the first RACH configuration when the condition is valid, and the second RACH configuration when the condition is not valid.

Abstract: Apparatuses and methods for resource selection for physical channels during initial access. A method of operating a user equipment (UE) includes receiving first information indicating a first partition of physical random access channel (PRACH) resources into a first group and a second group. A first PRACH transmission using a first PRACH resource from the first group of PRACH resources indicates a first set of features for the UE. A second PRACH transmission using a second PRACH resource from the second group of PRACH resources indicates a second set of features for the UE. The UE further includes determining a PRACH resource from the first group of PRACH resources or from the second group of PRACH resources and transmitting a PRACH using the determined PRACH resource in a RACH occasion (RO).

Abstract: Methods and apparatuses for power control of multiple uplink transmissions. A method for operating a user equipment includes receiving information for first parameters and for second parameters, determining a first power for a first channel with a first spatial setting to a first reception point of a serving cell using the first parameters, and determining a second power for a second channel with a second spatial setting to a second reception point of the serving cell using the second parameters. The method further includes transmitting, to the first reception point of the serving cell, the first channel using the first power and the first spatial setting; and transmitting, to the second reception point of the serving cell, the second channel using the second power and the second spatial setting.

Abstract: Apparatuses and methods for sidelink power control with carrier aggregation. A method of user equipment (UE) in a wireless communication system includes receiving a set of configurations for sidelink operation on multiple carriers from a higher layer and information for a maximum power for transmission on the multiple carriers and identifying, based on a UE capability a maximum number of physical sidelink feedback channels (PSFCHs) for simultaneous transmissions. The method further includes determining, based on the set of configurations, a first number of PSFCHs, PSFCH transmission occasions for the first number of PSFCHs in corresponding first number of carriers from the multiple carriers, and a power for transmission of a PSFCH from the first number of PSFCHs and simultaneously transmitting, in the PSFCH transmission occasions, the first number of PSFCHs with the power in the first number of carriers.

Abstract: Methods and apparatuses for use in a wireless communication. A method includes receiving first information providing first transmit power control (TPC) commands and second information providing a first number of slots for a transmission of a channel. The method further includes determining: a first set and a second set of transmission occasions for the channel over the first number of slots, a first power based on a first power control adjustment state, an accumulated value of the first TPC commands, a second power control adjustment state based on the first power control adjustment state and the accumulated value of the first TPC commands, and a second power based on the second power control adjustment state. The method further includes transmitting the channel with the first power in the transmission occasions of the first set and the second power in the transmission occasions of the second set.

Abstract: Methods and apparatuses for a RACH-less handover for a mobility operation in a wireless communication system. A method of a UE comprises: receiving a first message including configuration information for a RACH-less HO; determining whether the configuration information includes the CG configuration or the beam indication; identifying: a CG PUSCH occasion based on a determination that the configuration information includes the CG configuration, or a TCI state ID or a SSB index based on a determination that the configuration information includes the beam indication; and transmitting, to the target cell: an uplink signal including a second message in response to the first message at the identified CG PUSCH occasion when the configuration information includes the CG configuration, or the uplink signal based on an uplink grant received in a PDCCH, the PDCCH being monitored based on the beam indication when the configuration information includes the beam indication.

Abstract: Methods and apparatuses for power information for uplink configurations. A method includes receiving information indicating that a first downlink control information (DCI) format scheduling transmission of a physical uplink shared channel (PUSCH) includes a transform precoding indication (TPI) field and a channel providing a DCI format scheduling transmission of a first PUSCH. The method further includes determining whether the DCI format is the first or a second DCI format and a power headroom report (PHR). When the second DCI format, the PHR includes a single PHR associated with a transform precoding used for the transmission of the first PUSCH. When the first DCI format, the PHR includes first and second PHRs associated with first and second transform precodings, respectively, for the transmission of the first PUSCH. The method further includes transmitting the first PUSCH with the PHR using either the first or second transform precoding.
