Abstract: Apparatuses and methods for physical downlink control channel (PDCCH) monitoring for multi-cell scheduling. A method includes receiving information for a number of sets of cells and information for a user equipment (UE)-specific search space (USS) set for receptions of PDCCH candidates on a scheduling cell. The USS set has a USS set identity and is associated with a downlink control information (DCI) format for scheduling on more than one cell. The method further includes determining a set of cells, from the number of sets of cells, that is associated with the USS set and a reference cell from the set of cells. A size of the DCI format is counted in a number of sizes of DCI formats for scheduling on the reference cell and is not counted in a number of sizes of DCI formats for scheduling on cells, other than the reference cell, from the set of cells.

Abstract: Methods and apparatuses for inter user equipment (UE) coordination signaling. A method of operating a UE includes determining a first set of first sidelink (SL) resources based on SL sensing and resource exclusion; selecting a first one or more SL resources within the first determined set for reservation, transmitting information about the first one or more SL resources, and receiving inter UE co-ordination information indicating whether a SL resource in the first one or more SL resources has a conflict. The method further includes transmitting on one of the first one or more SL resources, when the one SL resource does not have a conflict; and determining a second set of SL resources based on SL sensing and resource exclusion, and selecting a second one or more SL resources within the second set for transmission and reservation, when all of the first one or more SL resources have a conflict.

Abstract: Apparatuses and methods for transmission timing for repeaters. A method for operating a network-controlled repeater (NCR) includes receiving, by an NCR mobile termination (NCR-MT) entity on an NCR control link, information for a timing value for an NCR forwarding (NCR-Fwd) entity. The method further includes determining, by the NCR, a timing adjustment for an NCR access link based on the timing value and a reference signal (RS). The method further includes receiving, by the NCR-Fwd entity on the NCR access link, a radio frequency (RF) signal based on the timing adjustment.

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.

Abstract: A method for acknowledgement information enhancement includes receiving first information for first cells; second information for second cells; first and second DCI formats; and N PDSCHs on N cells, from the second cells, which are scheduled by a DCI format from the second DCI formats. The method further includes determining first HARQ-ACK information bits associated with the first DCI formats and second HARQ-ACK information bits associated with the second DCI formats. The second HARQ-ACK information bits include, for the DCI format, M=Σi∈N Mi HARQ-ACK information bits corresponding to receptions of the N PDSCHs on N cells, in ascending order of cell indexes for the N cells and (Mmax−M) HARQ-ACK information bits with NACK values that are appended to the M HARQ-ACK information bits. The method further transmitting a channel that includes a HARQ-ACK codebook generated by appending the second HARQ-ACK information bits to the first HARQ-ACK information bits.

Abstract: Apparatuses and methods for acknowledgement information for multi-cell scheduling in a wireless communication system. A method of a user equipment (UE) includes receiving first information for a set of cells and second information for first time-domain resource allocation (TDRA) tables. The first TDRA tables correspond to respective first cells from the set of cells. An entry of a TDRA table from the first TDRA tables indicates a time resource for a physical downlink shared channel (PDSCH) reception on a cell from the first cells. The method further includes identifying a second TDRA table, determining acknowledgment information corresponding to the set of cells based on a union of rows of the first TDRA tables and the second TDRA table, and transmitting a physical uplink control channel (PUCCH) with the acknowledgment information. An entry of the second TDRA table indicates time resources for receptions of first PDSCHs on the set of cells.
