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 via a system information block (SIB), a random access configuration associated with aerial UEs, wherein the random access configuration indicates one or more aerial UE specific parameters. The UE may transmit, to the base station, a random access message during a random access procedure based at least in part on the one or more aerial UE specific parameters indicated in the random access configuration associated with aerial UEs. Numerous other aspects are described.

Abstract: A method, apparatus, and computer-readable medium are provided that improves power savings and reliability of communication for DRX/eDRX modes. A base station may receive an indication from a network entity that a UE is in a DRX/eDRX mode. The base station may configure a WUS mode for the UE corresponding to the DRX mode or the eDRX mode. A UE may receive the WUS mode from the base station. When a UE is configured for relaxed RRM measurements for a first cell and moves to a second cell that supports a relaxed RRM measurement, the UE may return to a regular RRM measurement for a time period. When a UE configured for a WUS mode for a first cell moves to a second cell that supports the WUS mode, the UE may return to the DRX mode or the eDRX mode without the WUS mode for a period of time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may establish a PC5 unicast link with a second UE. The UE may transmit, to a second UE in a PC5 radio resource control (RRC) message, capability information that includes an indication that the first UE is an unmanned aerial vehicle (UAV). Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A frame, scheduling instance, scheduling period etc. may include a set of downlink subframes and a set of uplink subframes. At least one control message transmitted in a downlink subframe may schedule a set of data messages in the downlink subframes of the frame. The downlink subframe may also include data messages scheduled by a control message of a previous frame. Further, feedback timings for data messages of the frame may be determined based on the corresponding control messages (e.g., from the current frame and the previous frame). Feedback responses corresponding to the data messages may be transmitted in a bundled manner in the set of uplink subframes. Using this cross-frame scheduling technique, the resources of a frame may be efficiently utilized.

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, radio resource control (RRC) signaling indicating a number of padding bits in multicast downlink control information (DCI). The UE may receive, from the base station, a multicast DCI message that includes a set of fields to indicate a set of communication parameters. The UE may interpret the multicast DCI message that indicates the set of communication parameters based at least in part on the number of padding bits indicated by the RRC signaling. 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 receive, from a wireless communication device, a measurement time indication for measuring at least one signal associated with at least one inter-frequency neighbor cell. The UE may receive the at least one signal associated with the at least one inter-frequency neighbor cell based at least in part on the measurement time indication. Numerous other aspects are provided.

Abstract: The present disclosure relates to transmitting and receiving a group wake-up signal (WUS) in conjunction with an ungrouped WUS. A base station may group one or more UEs in a UE group, while other UEs may not be assigned to a UE group. The configuration of WUS resources and WUS sequences for grouped UEs and other UEs is a challenge. The base station may transmit, to one or more UEs in the UE group, a resource allocation of a group WUS resource within a set of WUS resources associated with a paging occasion that is assigned to the one or more UEs in the UE group. A UE, after receiving the resource allocation, may determine a location of the group WUS resource within the set of WUS resources. The UE may monitor for a group WUS at the determined location in the resource allocation of the group WUS resource.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station on a granting group common (GC)-physical downlink control channel (PDCCH), a multimedia broadcast multicast service (MBMS) downlink grant that schedules an MBMS transmission at each UE of a group of UEs that includes the UE. The method also includes receiving, from the base station on a triggering GC-PDCCH, a message indicating respective feedback resources for each UE of the group of UEs. The method further includes receiving, from the base station, the MBMS transmission. The method still further includes transmitting, to the base station via the feedback resources, a feedback report based on receiving the MBMS transmission.

Abstract: Methods, apparatuses, and computer-readable medium for SRS are provided. An example UE may receive an SRS configuration and a downlink transmission scheduling an uplink transmission, the uplink transmission being scheduled on a CC, the SRS configuration comprising one or more additional SRS symbols relative to a first set of SRS symbols associated with an aperiodic trigger Type 1 or a periodic trigger Type 0, the one or more additional SRS symbols being scheduled on a destination CC at least one of the one or more additional SRS symbols overlapping at least partially with the uplink transmission. The example UE may drop or delay transmission of at least a part of an SRS in the one or more additional SRS symbols on the destination CC or at least a part of the uplink transmission on the source CC.
