The network node may transmit a second message comprising a TAC configuration associated with the TAC granularity based on the first indication. The network node may transmit the second message in response to receiving the first message. The UE may receive the second message. The network node may transmit a TAC. The UE may receive the TAC. The UE may transmit a third message based on the TAC configuration. The UE may transmit the third message in response to receiving the TAC. The network node may receive the third message. The network node may be a non-terrestrial network node, such as a satellite or a low-Earth orbit device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio resource control (RRC) configuration that indicates that hybrid automatic repeat request (HARQ) feedback associated with a downlink HARQ process is disabled or enabled. The UE may receive a downlink control information (DCI) communication that overrides the RRC configuration. The UE may selectively transmit HARQ feedback, associated with the downlink HARQ process, for a downlink transmission based at least in part on the DCI communication. The UE may selectively initiate, based at least in part on selectively transmitting the HARQ feedback, physical downlink control channel (PDCCH) monitoring associated with the downlink HARQ process based at least in part on at least one of the RRC configuration or the DCI communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. Various aspects relate generally to anchor cell management for a synchronization signal block (SSB)-less secondary cell (SCell). In some aspects, an anchor cell in a different frequency band from an SSB-less SCell may be used for downlink beam management of the SSB-less SCell. A UE may report, to a network node, reference signal received power (RSRP) measurements for a plurality of downlink reference signals transmitted via the anchor cell, and the network node may determine a downlink beam for the SSB-less SCell based at least in part on the RSRP measurements. The UE may receive a configuration of the SSB-less SCell, and the configuration may indicate the anchor cell associated with the SSB-less SCell. The UE may receive an activation indication that activates the SSB-less SCell for the UE.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) obtains one or more positioning measurements of one or more positioning reference signal (PRS) resources during one or more autonomous gaps scheduled within an autonomous gap window, the autonomous gap window, the one or more autonomous gaps, or both defined by one or more autonomous gap configuration parameters, wherein each of the one or more autonomous gaps comprises a period of time during which the UE at least prioritizes PRS reception and processing over reception, processing, or both of other downlink signals and channels, and reports the one or more positioning measurements to a positioning entity to enable the positioning entity to determine a location of the UE.

Abstract: A network node may transmit a first signal to a first radio at a user equipment (UE). The UE may receive the first signal from the network node. The first signal may include a first configuration for a second radio at the UE. The UE may operate the second radio in a first mode based on the first configuration received via the first radio. The first radio may have a lower power consumption than the second radio or the second radio may have the lower power consumption than the first radio. For example, one radio may be a low-power wake-up radio (LP-WUR) having a lower power consumption than a main radio (MR) at the UE. The network node and the UE may communicate with one another via the second radio at the UE based on the first configuration transmitted to the first radio.

Abstract: Aspects relate to activation of a cell (e.g., an SCell) based on measurements made by a user equipment (UE) when the cell is not activated with respect to (e.g., as a secondary cell for) the UE (e.g., the cell is deemed by the network as an unknown cell for that UE). In this case, when the network requests the UE to conduct measurements with respect to that cell (e.g., in conjunction with activation of the cell), the UE may report information based on the measurements the UE conducted when the cell was not activated with respect to that UE.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may transmit, and a user equipment (UE) may receive, signaling that indicates at least a first random access channel (RACH) occasion (RO) partition and a second RO partition. The first RO partition may be associated with different uplink transmission capabilities than the second RO partition. The UE may select an RO in the first RO partition or the second RO partition based at least in part on a metric that relates to an uplink transmission capability of the UE. The UE may transmit, and the network node may receive, a preamble in the selected RO to initiate a RACH procedure. Numerous other aspects are described.

Abstract: Systems and techniques are provided for wireless communications. For example, an apparatus (e.g., a user equipment (UE)) may receive a downlink transmission in a first downlink time slot and receiving an update to a scheduling offset associated with a propagation time delay of communications between the apparatus and a network entity. The update indicates an updated scheduling offset. The apparatus may determine a selected scheduling offset as one of the scheduling offset or the updated scheduling offset. The apparatus may transmit, using a second uplink time slot, an uplink transmission associated with the downlink transmission. The second uplink time slot may be determined based on a first uplink time slot and the selected scheduling offset.
