Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure event associated with the UE. The UE may detect a first condition of the UE. The UE may perform one or more actions associated with beam failure recovery based at least in part on a measure of similarity between the first condition of the UE and a second condition of the UE associated with a past beam failure event. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide techniques for using automatic gain control symbols to indicate a sidelink mini-slot. A method performed by a transmitting user equipment includes transmitting, during a first time portion of a symbol within a slot, a first beam associated with a first receiving user equipment. The first time portion of the symbol is configured to indicate that the first receiving user equipment will receive another transmission from the transmitting user equipment during a first mini-slot within the slot associated with the first time portion. The method may further include transmitting, during a second time portion of the symbol within the slot, a second beam associated with a second receiving user equipment. The second time portion of the symbol is configured to indicate that the second receiving user equipment will receive another transmission from the transmitting user equipment during a second mini-slot within the slot.

Abstract: Certain aspects of the present disclosure provide techniques for frequency tracking and timing tracking using wideband reference signals (RSs). A method that may be performed by a user equipment (UE) includes monitoring for a wideband RS from a network entity when one or more conditions are met, the wideband RS occupying a wider band of frequency resources than a tracking reference signal (TRS) transmitted by the network entity; and performing at least one of frequency tracking or timing tracking based on the monitoring.

Abstract: Methods, systems, and devices for wireless communications are described. Disclosed techniques provide for reliable and secure sharing of configuration parameters over physical layer reference signals. A first network node may transmit a first signal conveying a first phase to a second network node. The second network node may transmit a second signal conveying a second phase, the second phase based on the first phase and an authentication parameter common to the first and second network nodes. The first network node may determine that the second phase is based on the first phase and the authentication parameter. Based on determining that the second phase is based on the authentication parameter, the first network node may transmit a third signal conveying a third phase to the second network node, the third phase indicating a signature parameter. The first network node and the second network node may communicate based on the signature parameter.

Abstract: Certain aspects of the present disclosure provide techniques for beam failure detection per beam. A method that may be performed by a user equipment (UE) includes communicating with a network entity via a plurality of beams associated with a cell; performing a beam failure detection procedure per beam of the plurality of beams; and triggering a beam failure recovery procedure for a first beam of the plurality of beams in response to detecting a first beam failure for the first beam.

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, a transmission part (TP) hopping configuration that indicates one or more TPs and a TP hopping pattern associated with one or more hops between the one or more TPs. The UE may communicate, with the base station, using a TP of the one or more TPs based at least in part on the TP hopping configuration. Numerous other aspects are described.

Abstract: Aspects described herein relate to detecting maximum permissible exposure (MPE) events and/or reporting the MPE event, related metrics, associated requests for beam switching or new time division duplexing (TDD) patterns, etc. In an aspect, a MPE event can be detected on at least one component carrier (CC) of multiple CCs configured with a first cell in inter-band carrier aggregation (CA), and one of a MPE report or a beam switching request can be transmitted to a second cell on a different CC of the multiple CCs. In another aspect, the cell can detect the MPE and can transmit, to the device, a beam switching command to switch to a new beam for uplink communications. In another aspect, the cell can transmitting, to another cell having another CC of the multiple CCs configured with the device, an indication to perform beam switching for the device.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.

Abstract: Aspects are provided allowing a UE to transmit repetitions of an ULT, PEI-R, or other uplink reference signal for on-demand SSB, RMSI, or paging transmissions. A base station initially transmits an indication of a configured uplink repetition mode, which may comprise a first, second, or third mode in which a one-to-one, one-to-many, or many-to-many mapping exists between downlink reference signals and uplink occasions, respectively. Afterwards, the UE receives downlink reference signals via different transmission beams of the base station. In response to the downlink reference signals, the UE transmits an uplink reference signal repetition in one or more uplink occasions associated with one or more of the downlink reference signals according to the configured uplink repetition mode. In response to the uplink reference signal repetition, the base station may transmit a SSB, RMSI, or paging message. Thus, a balance between network energy savings and uplink signal reliability may be achieved.
