Abstract: Aspects described herein relate to communicating with one or more cells for receiving a broadcast service, and providing broadcast service continuity in device mobility scenarios. In some aspects, a user equipment (UE) can transmit a broadcast service interest indication to a serving cell to facilitate receiving the broadcast service during mobility to provide the broadcast service continuity.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for maximizing the potential of resources dedicated to aerial user equipment (UEs). In one example, a UE may receive signaling indicating that a cell supports communications exclusively with aerial UEs. The signaling may be used to bar non-aerial UEs from accessing the cell and reserve resources for communications with aerial UEs. In another example, a UE may receive signaling identifying one or more frequency bands dedicated to aerial UEs. The UE may then communicate on the one or more frequency bands. In yet another example, a UE may receive signaling indicating a set of aerial access categories supported by a cell. The signaling may be used to reserve resources for high-priority aerial UEs (e.g., aerial UEs used for law enforcement purposes).

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may support both unicast and multicast downlink signaling, such as on a single component carrier (CC). A UE may receive a unicast message over a first CC during a transmission time interval (TTI) using a first set of processing resources. The UE may simultaneously receive a multicast message over the first CC during the same TTI using a second set of processing resources. The first and second sets of processing resources may be associated with first and second hybrid automatic repeat request (HARM) soft buffers, first and second CCs, or first and second transmit/receive points (TRPs).

Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of subcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool, a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations within a resource pool in the same bandwidth part.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a non-terrestrial network (NTN) entity, a message that is associated with an uplink grant. The UE may select, based at least in part on the message, either a cell-specific offset or an updated offset that is indicated after initial access, as a timing offset that accounts for a propagation delay between a base station of the NTN and the UE. The UE may transmit, to the NTN entity, an uplink communication using the timing offset. Numerous other aspects are described.

Abstract: A radio access network (RAN) node may transmit, to an access and mobility function (AMF) of a core network, a request associated with a location-based state of a user equipment (UE) served by the RAN node. The location-based state of the UE may be associated with whether the UE is flying or whether the UE is driving, or other location information of the UE. Accordingly, the RAN node may receive a message in response to the request. The RAN node may receive the message in response to the request from the AMF. Alternatively, the AMF may establish a connection between the RAN node and a location management function (LMF) of the core network such that the RAN node receives the message in response to the request from the LMF.

Abstract: Certain aspects of the present disclosure provide techniques for providing feedback. For example, a user equipment (UE) may receive, from a network node, a configuration of a search space comprising time and frequency resources available to the network node for communicating a downlink control channel, the configuration indicating a feedback process type corresponding to the search space. The UE may also receive, from the network node, the downlink control channel in the search space. The UE may also receive a downlink transmission scheduled by the downlink control channel. The UE may selectively provide feedback to the network node regarding decoding of the downlink transmission according to the feedback process type corresponding to the search space.

Abstract: Apparatus, methods, and computer program products for handover are provided. An example method may include receiving a physical downlink shared channel (PDSCH) transmission from a network entity, the PDSCH transmission comprising a set of radio resource control (RRC) messages, each RRC message in the set of RRC messages comprises a respective group handover configuration in a set of group handover configurations associated with a respective UE in a set of UEs including the UE, the set of RRC messages being included in a set of medium access control (MAC) service data units (SDUs) (MAC SDUs) in a MAC protocol data unit (PDU). The example method may further include processing a first subset of the MAC SDUs that are associated with the UE and discard a second subset the MAC SDUs that are not applicable to the UE.
