Abstract: Wireless communications systems and methods related to joint-carrier scheduling using a single downlink control information (DCI) signal. The user equipment (UE) receives from a base station (BS) of a first serving cell, a downlink control information (DCI) that indicates a joint-carrier scheduling scheme. Using the joint-carrier scheduling scheme in the DCI, the UE schedules first data for communication on a first shared channel associated with the first serving cell and second data for communication on a second shared channel associated with a second serving cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from an entity of a non-terrestrial network (NTN), a system information block (SIB) that indicates information relating to one or more NTN SIBs that are to include at least one of ephemeris information or feeder link timing advance information. The UE may receive, from the entity of the NTN, the one or more NTN SIBs based at least in part on the information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that indicates whether a common search space (CSS) is associated with a first type of physical downlink control channel (PDCCH) or a second type of PDCCH. The first type of PDCCH may correspond to a cell-broadcast PDCCH and the second type of PDCCH may correspond to a UE-specific PDCCH. The CSS may be for downlink control information (DCI) with a cyclic redundancy check scrambled by a group radio network temporary identifier (G-RNTI) that schedules a multicast and broadcast service (MBS). The UE may receive, from the base station, the first type of PDCCH or the second type of PDCCH. Numerous other aspects are described.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a plurality of repetitions of a cell-common wakeup signal (WUS) on a different transmit beam in each monitoring occasion of one or more monitoring occasions. Another apparatus may beam sweep receive beams in each monitoring occasion to receive the cell-common WUS and to identify a transmit beam/receive beam pair for receiving a paging communication in a paging occasion associated with the transmit beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment concurrently communicates with a source base station (BS) and a target BS on a connection with the source BS and a connection with the target BS as part of a make-before-break (MBB) handover procedure; and performs a common packet data convergence protocol (PDCP) function for the connection with the source BS and the connection with the target BS before the connection with the source BS is released as part of the MBB handover procedure. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a reference time for updating one or more system information parameters associated with a non-terrestrial network (NTN) or updating a cell status associated with the NTN. The UE may determine an update timer length for updating the one or more system information parameters associated with the NTN or the cell status associated with the NTN. The UE may acquire, from a current cell or a new cell, a system information block (SIB) to refresh the one or more system information parameters after an expiration time associated with the one or more system information parameters, wherein the expiration time is based at least in part on the reference time and the update timer length. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for resource allocation and hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback for multi-cell scheduling. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), a configuration for a plurality of carriers, receiving, from the BS, control information indicating whether resources for a data channel are allocated in a concatenated pair of carriers of the plurality of carriers, and communicating on the data channel with the BS based on the control information.
