Abstract: Aspects of the disclosure relate to millimeter wave (mmWave) device discovery for relay communication using pseudo-omnidirectional beams. A first user equipment (UE) may transmit a synchronization signal over each pseudo-omnidirectional beam to enable a second UE to discover a presence of the second UE within a range of the first UE. Upon the occurrence of an external event, a base station may either trigger a beam training procedure with the second UE to establish a relay link between the first and second UEs or broadcast a message to all UEs requesting a relay link be established with the first UE. The first and second UEs may then select a directional beam pair link (BPL) for the relay link and establish the relay link to enable information to be relayed between the base station and the first UE via the relay link.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of an update associated with a non-serving cell reference signal. The UE may select a first application time duration based at least in part on a determination that the non-serving cell reference signal has been tracked by the UE or a second application time duration based at least in part on a determination that the non-serving cell reference signal has not been tracked by the UE, resulting in a selected application time duration. The UE may apply the update associated with the non-serving cell reference signal after the selected application time duration. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a transmission configuration indicator (TCI) state application time for at least one common multi-channel TCI state. A method that may be performed by a user equipment (UE) includes receiving a TCI state indication from a network, wherein the TCI state indication comprises at least one common multi-channel TCI state, and configuring a TCI state application time for the at least one common multi-channel TCI state based on one or more factors.

Abstract: In some aspects, a user equipment (UE) receives scheduling information that schedules a channel state information reference signal (CSI-RS). The UE determines whether to autonomously update a transmission configuration indicator (TCI) state in response to the scheduled CSI-RS based, for example, on CSI-RS power metrics or payload size of a CSI report. Then, depending upon the determination, the UE either autonomously updates the TCI state or updates the TCI state only in response to TCI state update instructions received from the base station. In other aspects, a UE receives scheduling information from a multiple transmission and reception point (mTRP) base station that schedules a CSI-RS. The UE autonomously updates TCI states for use with the mTRP base station. Complementary operations may be performed by the base station. These and other aspects described herein may reduce latency and improve performance between a UE and a base station.

Abstract: Aspects described herein relate to determining one of multiple antenna panels to use to receive downlink beams based on whether a configuration from a base station indicates an antenna panel associated with the downlink beam or in determining a number of repetitions of a downlink beam to receive in beam refinement.

Abstract: Aspects described herein relate to activating, by a user equipment (UE), or causing activation of, by a base station, one or more antenna panels at the UE. An action time for activating or deactivating the one or more antenna panels may also be used to allow processing time related to activation or deactivation of the antenna panels.

Abstract: A plurality of scheduled entities, such as transmission reception points (TRPs), may each transmit at least one TRP-specific beam failure detection reference signal (BFD-RS) having a corresponding TRP identifier (ID) to a scheduled entity. The scheduled entity may be configured with at least one TRP-specific medium access control (MAC) parameter. The scheduled entity may receive the TRP-specific BFD-RSs and respective TRP IDs associated therewith. The scheduled entity may measure each BFD-RSs and count beam failure instances associated with each TRP ID. The scheduled entity may transmit a beam failure recovery request (BFRQ) associated with the respective TRP ID in response to a predetermined quantity of respective TRP-specific BFD-RS measurements of at least one of the respective TRP-specific BFD-RSs being less than a predetermined value. A scheduling entity may receive the BFRQ, where the at least one TRP-specific MAC parameter was used to trigger the BFRQ.

Abstract: Aspects of the present disclosure provide techniques for configuring multi-beam full-duplex communication that allows a device (e.g., user equipment (UE) or base station) to contemporaneously perform both uplink and downlink communication over the same frequency band. Because of the full duplex communication capability provided by the present disclosure, the NR system may achieve reduced latency and improved spectrum and resource efficiency, thereby accommodating a growing demands for the wireless communication. The full duplex communication capability may be achieved by implementing downlink control information (DCI) format that specifies to the UE the beam assignments for contemporaneous transmission (Tx) and reception (Rx). Particularly, beams may be selected such that the beam(s) assigned for communication are independent and uncorrelated, and therefore provide sufficient beam diversity in order to mitigate the limitations of current systems, including self-interference that has hindered implementation of full duplex communication in current systems.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a tracking reference signal (TRS) pattern to be used for receiving a TRS. The TRS pattern may indicate a plurality of TRS symbols of the TRS, one or more TRS symbols of the plurality of TRS symbols having a bandwidth that is different than a bandwidth of at least one other TRS symbol of the plurality of TRS symbols, or having a discontinuous tone allocation. The UE may receive the TRS based at least in part on the TRS pattern. Numerous other aspects are provided.
