    Abstract: Satellites in a non-terrestrial network may provide positioning reference signals (PRS) to user equipment (UE), with which the UE may determine its position using propagation delay difference measurements, such as Time Difference of Arrival (TDOA) measurement. Due to the large distances between satellites and the UE, the propagation delay differences in the PRS received from satellites may exceed half a radio frame, resulting in a frame level timing ambiguity in the differential measurements. The satellites transmit secondary PRS, along with primary PRS, that include timing information to resolve frame level timing ambiguity of the primary PRS. The positioning occasions in the secondary PRS, for example, may be aligned with corresponding positioning occasions primary PRS within each radio frame, and are transmitted with a periodicity that is an integer multiple (greater than 1) of that of the primary PRS to resolve the frame level timing ambiguity of the primary PRS.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a physical downlink control channel (PDCCH) communication in a first dynamic control resource set (CORESET) configured in a first bandwidth part (BWP). The PDCCH communication may indicate a BWP switch from the first BWP to a second BWP. The UE may determine, based at least in part on the BWP switch, whether to monitor one or more second dynamic CORESETs, subsequent to the first dynamic CORESET, that were configured in the first BWP. The UE may selectively monitor the one or more second dynamic CORESETs based at least in part on determining whether to monitor the one or more second dynamic CORESETs. Numerous other aspects are provided.

    Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

    Abstract: Methods, systems, and devices for wireless communications are described Generally, the described techniques provide for a user equipment (UE) to perform a beam switching operation from a current beam to a target beam based on a beam switching duration. The UE may transmit a capability report that may include an antenna pointing capability, a list of one or more detailed capabilities, or both to another device, such as a network entity (e.g., a satellite). The UE may perform the beam switching operation based on the capability report. The UE may perform a random access procedure as part of a change of association operation. The UE may receive a control message from the other device, which may be the network entity, that includes an identity of a target network entity, one or more resources for the random access procedure, an indication of the beam switching duration, or any combination.
