    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving node associated with a non-terrestrial network (NTN), one or more timing advance (TA) values. The UE may transmit, to the serving node of the NTN, uplink signaling based at least in part on a reference timing for the uplink signaling, wherein the reference timing for the uplink signaling is based at least in part on a reference timing of a downlink signaling and the one or more TA values, wherein the one or more TA values include a UE-specific TA value, and wherein a reference timing of the UE-specific TA value is for: a first propagation delay on a service link between the UE and a satellite associated with the NTN, and a second propagation delay on the service link. Numerous other aspects are described.

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques and devices for uplink gap configuration. Certain aspects are directed to an apparatus for wireless communications at a user equipment (UE). The UE may include a memory comprising instructions, and one or more processors configured to execute the instructions. In some examples, the instructions may cause the apparatus to obtain, from a base station, a first time division duplex (TDD) configuration for wireless communications between the UE and the base station. The instructions may cause the apparatus to obtain, from the base station, an uplink gap pattern (ULGP) configuration indicating a first ULGP associated with a first time window and the first TDD.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source base station, configuration information for a handover, wherein the configuration information indicates, for a target non-terrestrial cell, timing and synchronization parameters including a scheduling timing offset, a round trip time between a reference point and a target base station associated with the target non-terrestrial cell, satellite ephemeris information, an ephemeris validity duration associated with the satellite ephemeris information, common timing advance parameters, and a common timing advance validity duration associated with the common timing advance parameters. The UE may perform the handover with the target base station associated with the target non-terrestrial cell based at least in part on the timing and synchronization parameters for the target non-terrestrial cell. Numerous other aspects are described.

    Abstract: Certain aspects of the present disclosure provide techniques for providing direct current locations of bandwidth parts (BWPs) in a BWP hopping pattern. Certain aspects relate to a method for wireless communication by a user equipment (UE). In some examples, the UE may receive, from a base station (BS), a request for uplink direct current location information of the UE, wherein the UE is configured to transmit to the BS on an uplink according to a frequency hopping pattern for hopping between a plurality of uplink bandwidth parts corresponding to different frequency bandwidths. In some examples, the UE may transmit, to the BS, at least one uplink direct current location applicable to the plurality of uplink bandwidth parts. In some examples, the UE may transmit, to the BS, on the uplink according to the frequency hopping pattern.
