Abstract: The present disclosure relates to apparatus and methods of signal to interference and noise ratio (SINR)-based group beam reporting. In particular, this disclosure relates to measurement report configurations for initiating a protocol layer 1 (L1)-SINR based group beam report, and corresponding measurement resource transmissions by a base station and measurement and reporting actions of the UE to report the L1-SINR for each of at least two beams that can be simultaneously received. The measurement report configurations include a channel measurement resource (CMR) configuration, an interference measurement resource (IMR) configuration, or both. The measurement configuration may indicate a plurality of CMR repetition sets, or N resource sets of 1 CMR resource plus N−1 IMRs, e.g., 1 CMR mapped to N−1 IMRs, or N×(N−1) resource sets of a CMR and an IMR, e.g., 1 CMR mapped to 1 IMR, where N is the number of candidate Tx beams.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, at a user-equipment (UE), at least one pilot signal via a secondary cell, receive, via a primary cell, a first message triggering reporting of at least one preferred beam for communication via the secondary cell, determining the preferred beam based on the at least one pilot signal, transmitting, via the primary cell, a report indicating the at least one preferred beam, and communicating data via the secondary cell and via the preferred beam.

Abstract: This disclosure provides methods, devices and systems related to UE-aided selective single frequency network (SFN). In some implementations, a UE may obtain a first channel measurement of a first communication channel associated with a serving transmission and reception point (TRP), and a second channel measurement of a second communication channel associated with a neighbor TRP. The UE may further select an SFN condition associated with the first channel measurement or the second channel measurement, and transmit an indication including the SFN condition to one or both of the serving TRP or the neighbor TRP. In some other implementations, a network entity may select whether to configure a transmission scheme according to SFN for at least one of a serving TRP and a neighbor TRP associated with the SFN condition, and communicate with the UE associated with the transmission scheme according to SFN.

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.
