Abstract: This disclosure provides methods, devices and systems for facilitating device-to-device (D2D) communications on sidelinks. Some implementations more specifically relate to a user equipment (UE) determining sidelink communication parameter corresponding to UE assistance information or UE capability information. The UE may also determine an attribute associated with the sidelink communication parameter, the attribute indicating the sidelink communication parameter is a dynamic parameter or a static parameter. The UE may further transmit to another UE, on a sidelink, the sidelink communication parameter and the attribute. The UE may also communicate with the other UE on the sidelink based on the transmitted sidelink communication parameter and the attribute.

Abstract: There may be a gap between the time a beam pair link (BPL) impacted by a beam failure (BF) event is deactivated and the time a replacement BPL is activated and becomes fully functional at a UE. The gap may be called a blackout period. A base station may not know the blackout period and may continue transmitting to the UE on the impacted BPL during the blackout period. This may result in a transmission failure. Disclosed herein are apparatus and methods for determining a blackout period associated with a beam failure (BF) event and communicating a blackout indication to a base station, the blackout indication including the blackout period.

Abstract: Certain aspects of the present disclosure provide techniques for uplink transmit beam update using uplink transmission configuration indicator (TCI) states. An example method generally includes receiving, from a network entity, signaling of an uplink transmission configuration indicator (TCI) state update for one or more uplink transmissions. The example method generally includes determining the uplink TCI state update is to be applied for dynamically scheduled uplink transmission, semi-persistently scheduled uplink transmission, or periodic uplink transmission. The example method generally includes applying the uplink TCI state update to one or more uplink transmissions in accordance with the determination.

Abstract: A configuration to configure a UE to activate a subset of configured SRS trigger states. The apparatus receives a configuration activating a subset of configured SRS trigger states. The apparatus receives DCI in a PDCCH triggering an aperiodic SRS transmission based on one or more SRS trigger states of activated SRS trigger states. The apparatus determines an aperiodic SRS resource set based on the configuration and the DCI indicating the one or more SRS trigger states. The apparatus transmits aperiodic SRS within the aperiodic SRS resource set.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an uplink transmission configuration indication (TCI) state. The UE may determine that the uplink TCI state identifies a pathloss reference signal for an associated uplink transmission. The UE may determine an uplink power control parameter for the uplink transmission based at least in part on the pathloss reference signal. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for updating beam information across a plurality of component carriers (CCs) via downlink control information (DCI). An exemplary method, performed by a user equipment (UE), generally includes receiving, from a network entity, a downlink control information (DCI) for an update for at least of a beam or path loss (PL) reference signal (RS) activation and applying the update across at least one of a group of component carriers (CCs) or bandwidth parts (BWPs) within the group of CCs.

Abstract: Disclosed are techniques for computing and reporting a relevance metric for a positioning beacon beam. In an aspect, a first node receives, from a second node, a plurality of beams, determines a relevance metric for each of one or more beams of interest from the plurality of beams, wherein the relevance metric for each beam of the one or more beams of interest is based on a time of arrival at the first node of the beam and a signal strength of the beam, and sends, to the second node, a report identifying each of the one or more beams of interest and including the relevance metric for each of the one or more beams of interest.
