Abstract: A user equipment (UE) communicates with a further UE via a sidelink and communicates with a cell of a network via an uplink. The UE receives a hybrid automatic repeat request (HARQ) acknowledgement (ACK) timing parameter from the network, generates a sidelink HARQ-ACK codebook based on a signaling exchange with the further UE, wherein the sidelink HARQ-ACK codebook is constructed in decreasing order of one or more physical sidelink shared channel (PSSCH) transmission slots associated with a configured physical sidelink feedback channel (PSFCH) occasion, and transmits an indication of the sidelink HARQ-ACK codebook to the cell of the network.

Abstract: A user equipment (UE) is configured to use multiple beams for transmission or reception. The UE receives, from a base station, at least one medium access control (MAC) control element (CE) that indicates multiple activated transmission configuration indicator (TCI) states, receives, from the base station, at least one downlink control information (DCI) indicating a subset of TCI states of the multiple activated TCI states, wherein the MAC CE and the DCI are part of a TCI configuration, and wherein the subset of TCI states corresponds to multiple transmission and reception points (TRPs) of a wireless network, maps the subset of TCI states to the corresponding multiple TRPs based on the TCI configuration and selects a beam used for transmission or reception based on one mapped TCI state of the mapped subset of TCI states.

Abstract: A user equipment (UE) performs uplink (UL) transmissions to a network. The UE receives a frequency domain resource allocation (FDRA) configuration from a network, the FDRA configuration comprising at least one of a first FDRA mode or a second FDRA mode, wherein the first FDRA mode utilizes an FDRA unit comprising a set of consecutive resource blocks (RBs) and the second FDRA mode utilizes an FDRA unit comprising a set of interlaced RBs, when both of the first and second FDRA modes are configured, the UE receives a signal indicating which one of the two FDRA modes are to be used for an uplink (UL) transmission and performs the UL transmission in accordance with the indicated FDRA mode.

Abstract: A user equipment (UE) includes a set of one or more transceivers and a processor. The processor is configured to determine, at least partly from a transmission control indicator (TCI) state for multiple channels, that common physical downlink shared channels (PDSCHs) do not share a beam with dedicated PDSCHs. The processor is also configured to determine a physical downlink control channel (PDCCH)/PDSCH scheduling offset is below a threshold; select, at least partly based on the determination that common PDSCHs do not share a beam with dedicated PDSCHs and the determination the PDCCH/PDSCH scheduling offset is below the threshold, a beam for which to buffer PDSCH; and buffer PDSCH received on the beam.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.
