Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an unmanned aircraft system service supplier (USS) may receive a first notification indicating that a user equipment (UE) is moving out of an area associated with the USS. The USS may determine a target USS based at least in part on the first notification. The USS may transmit, to an unmanned aircraft system network function (UAS-NF), a second notification. The second notification may indicate that the UE is reallocated to the target USS. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) switch between carriers of a group of a carriers during uplink communications in accordance with a mapping. For example, the UE may report its capability to a base station for switching between carriers of the group, where the group includes a supplementary uplink (SUL) carrier and two or more normal uplink (NUL) carriers that are each associated with a different radio frequency band. The base station may indicate for the UE to switch to a subset of carriers of the group corresponding to a combination of radio frequency bands for transmission of an uplink message. The UE may switch to at least one carrier of the subset of carriers in accordance with a mapping that is based on the reported capability and may transmit the uplink message on the at least one carrier.

Abstract: Aspects presented herein may enable a location of a UE accessing a network via non-3GPP access to be determined or estimated. In one aspect, a UE establishes a connection with at least one network entity and a non-network connection entity. The UE transmits, to the at least one network entity, an ID of the non-network connection entity when connected to the at least one network entity. The UE receives, from the at least one network entity, a request for a location of the non-network connection entity. The UE transmits, to the at least one network entity, an indication of location information for the non-network connection entity.

Abstract: Aspects are provided which improve RLM by allowing a UE to apply a longer monitoring window for out-of-sync determinations before the UE triggers an RLM timer for in-sync determinations. The UE first obtains a reference signal from a base station. The UE then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. For example, the UE may perform looped out-of-sync monitoring, multi-cell or carrier monitoring, or a combination of such monitoring to determine the multiple groups of out-of-sync indications. Afterwards, the UE triggers the RLM timer in response to determining the multiple groups of consecutive out-of-sync indications. As a result, the UE may perform additional out-of-sync monitoring during RLM before proceeding with in-sync monitoring, thus allowing the UE to account for rapid BLER changes (ping-pong effects) that may occur in HAPS systems due to tropospheric turbulence and enabling more accurate RLM determinations and minimal RLF detections.

Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a plurality of broadcast sidelink communication protocol vehicular communication packets. The UE may process a set of packets of the plurality of broadcast sidelink communication protocol vehicular communication packets based at least in part on a determination that the set of packets are addressed only to the UE. Numerous other aspects are provided.

Abstract: Techniques and apparatus for achieving multi-cell synchronization for dual connectivity and carrier aggregation are described. In one technique, a timing difference between a first base station (BS) and a second BS is determined, where the first BS is in an asynchronous timing configuration with respect to the second BS. A measurement configuration for measuring signal(s) from the second BS is determined, based on the timing difference. The measurement configuration is signaled to a user equipment (UE) served by the first BS. The UE performs a measurement procedure for the signal(s) in accordance with the measurement configuration. In another technique, the second BS receives a synchronization request, which includes a first time stamp, from the first BS via a network interface between the first BS and the second BS. The second BS sends a synchronization response, which includes a second time stamp, to the first BS.
