    Abstract: Apparatuses and methods for uplink (UL) control signaling for multiple serving cells. A method includes receiving first information for a first set of operation states for first one or more cells, second information for a second set of operation states for second one or more cells, and third information for a resource for transmission of a channel. An operation state from the first set of operation states or the second set of operation states is associated with sets of parameters for transmissions or receptions in at least one of time, frequency, and spatial domains. The method further includes determining one or more first operation states from the first set of operation states and one or more second operation states from the second set of operation states and transmitting the channel using the resource. The channel indicates the one or more first and second operation states.

    Abstract: Apparatuses and methods for sidelink and uplink transmissions and receptions. A method performed by a user equipment (UE) includes receiving first information for sidelink operation on multiple sidelink carriers. The first information includes priority values associated with the multiple sidelink carriers. The method includes determining a first number of sidelink carriers from the multiple sidelink carriers based on the priority values, first simultaneous transmissions or receptions on the first number of sidelink carriers based on the first information, a first sidelink carrier from the multiple sidelink carriers, wherein the first sidelink carrier is not in the first number of sidelink carriers, and whether to postpone or drop a first transmission or reception on the first sidelink carrier based on a physical channel associated with the first transmission or reception. The method further includes transmitting or receiving the first simultaneous transmissions or receptions on the first number of sidelink carriers.

    Abstract: Methods and apparatuses for physical uplink control channel (PUCCH) transmission with hybrid automatic repeat request-acknowledgement (HARQ-ACK) information in a wireless communication system. A method performed by a user equipment (UE) includes receiving information for a first set of PUCCH resources for a transmission of a PUCCH on a primary cell and a set of numbers for repetitions of the transmission of the PUCCH and receiving a physical downlink control channel (PDCCH) providing a downlink control information (DCI) format that includes a downlink assignment index (DAI) field and a PUCCH resource indicator field. The method further includes determining a PUCCH resource from the first set of PUCCH resources based on the PUCCH resource indicator field; determining the number of repetitions, from the set of numbers of repetitions, based on the DAI field; and transmitting the PUCCH with the number of repetitions using the PUCCH resource on the primary cell.

    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 wideband operation on an unlicensed sidelink (SL). A method performed by a user equipment (UE) includes determining a sidelink (SL) bandwidth part (BWP); determining a set of resource block sets (RB-sets) and a set of intra-cell guard bands between the set of RB-sets; and determining, based on the set of RB-sets, a resource pool. A lowest RB of the resource pool is aligned with a lowest RB of a first RB set, and a highest RB of the resource pool is aligned with a highest RB of a second RB set. The method further includes determining, based on the resource pool, a set of sub-channels, determining, based on the set of sub-channels, a transmission of a physical SL shared channel (PSSCH), performing a SL channel access procedure, and performing the transmission of the PSSCH after successfully performing the SL channel access procedure.

    Abstract: Apparatuses and methods for power control for physical random access channel transmissions. The method includes receiving a synchronization signal and physical broadcast channel (SS/PBCH) block based on a first spatial filter, determining a first power for a physical random access channel (PRACH) based on the SS/PBCH block, and transmitting first more than one PRACHs using respective first spatial filters. Each of the first spatial filters has a narrower beam-width than the first spatial filter. A power for each of the first more than one PRACH transmissions is the first power.

    Abstract: Timelines for transmissions and receptions in random access. A method includes transmitting a first physical random access channel (PRACH) preamble in a first PRACH occasion (RO) using a first spatial setting and a second PRACH preamble in a second RO using a second spatial setting. The method further includes determining a first time window over a first number of symbols for reception of a first physical downlink control channel (PDCCH) scheduling reception of a first physical downlink shared channel (PDSCH) using a first transmission configuration indication (TCI) state and a second time window over a second number of symbols for reception of a second PDCCH scheduling reception of a second PDSCH using a second TCI state. The method further includes receiving the first PDCCH and the first PDSCH using the first TCI state or the second PDCCH and the second PDSCH using the second TCI state.
