Abstract: A first UE may obtain at least one parameter associated with an Rx timing of one or more CLI measurement resources. The one or more CLI measurement resources may be associated with CLI between the first UE and at least one second UE. The first UE may further refrain from receiving one or more serving DL channels or resources from a network node during the Rx timing based on the at least one parameter. The one or more serving DL channels or resources may overlap with at least one symbol of the one or more CLI measurement resources.

Abstract: Systems and techniques are provided for wireless communications at a network entity. For example, then systems and techniques can include determining, at the network entity, a transmission timing compensation between a first reference signal and a second reference signal. The first reference signal can be transmitted using a first communication link. The second reference signal can be transmitted based on an offset determined based on the transmission timing compensation, wherein the second reference signal is transmitted suing a second communication link. The offset can be used to offset transmission of the second reference signal from transmission of the first reference signal.

Abstract: A scheduling offset between an uplink and downlink radio frame timing structure of a user equipment (UE) may be updated to provide for more efficient utilization of hybrid automatic repeat request (HARQ) processes in a non-terrestrial network. For instance, different UEs may experience different round trip delays (RTDs) with a non-terrestrial cell. Different UEs may be configured with different scheduling offsets such that scheduling delays may be reduced and HARQ processes identifiers may be reused more rapidly. Additionally or alternatively, wireless communications systems may define one or more separation distances (or timing thresholds) for timing between communications and HARQ processes may be reused based on the separation distance threshold (e.g., such that a satellite may reuse a HARQ process ID for two scheduled communications that have not yet been performed by the UE).

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: 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may configure one or more transmission parameters to maintain a channel consistency for a transmission channel. The UE may transmit, via the transmission channel, a set of multiple communications using the one or more transmission parameters. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communications by a user equipment (UE). The UE detects one or more conditions are met for transmitting a medium access control (MAC) control element (CE) providing assistance information to a network entity for scheduling. In response to the detection, the UE then takes one or more actions to obtain uplink (UL) resources for transmitting the MAC CE.

Abstract: Aspects of the present disclosure provide systems and methods for informing a user equipment (UE) that which beam the UE is being served, for example, such as in relation to bandwidth part (BWP) switching in a non-terrestrial network (NTN). According to certain aspects, a network entity may transmit to a user equipment (UE) signaling indicating at least one BWP switch. The network entity provides, to the UE, an indication of a serving synchronization signal block (SSB) for the UE to use after the BWP switch.

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.
