Abstract: Certain aspects of the present disclosure provide techniques for a synchronization signal block (SSB)-level sleep mode. A method that may be performed by a user equipment (UE) includes determining, from a synchronization signal burst set, a first set of synchronization signal blocks (SSBs) to forgo performing measurements on using one or more receive beams based, at least in part, on one or more previous measurements associated with the determined first set of SSBs and performing measurements on only one or more remaining SSBs in the synchronization signal burst set using the one or more receive beams.

Abstract: A UE is configured to determine a set of parameters associated with receiving the SSBs, the set of parameters including a first parameter bitmap associated with a serving cell, a second parameter bitmap associated with the neighbor cell, and the SMTC. The UE is configured to determine a search window for searching the received SSBs based on the SMTC and at least one of the first parameter bitmap or the second parameter bitmap. The UE may measure the SSBs searched during the determined search window and send measurement results associated with at least a subset of the measured SSBs to the base station. The UE may also prune measurements to generate the measurement results by removing measurements associated with SSBs received in slots that are not indicated to expect SSBs, based on the first parameter bitmap, the second first parameter bitmap, or the SMTC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE. In some aspects, the information indicating the L1-SINR measurement capability may include one or more individual configurations for one or more resources to carry a reference signal. The UE may receive, from the base station, a reference signal carried on the one or more resources based at least in part on the L1-SINR measurement capability. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for beam failure detection and recovery. A method that may be performed by a user equipment (UE) includes monitoring one or more first reference signals to detect a beam failure for one or more first control resource sets (CORESETs), transmitting an indication of the beam failure, and receiving a beam failure response after the transmission of the indication of the beam failure, wherein the monitoring of the one or more first reference signals for the detection of the beam failure stops in response to the reception of the beam failure response. The UE may then receive a configuration message after the reception of the beam failure response, and monitor, in response to the reception of the configuration message, one or more second reference signals to detect another beam failure for one or more second CORESETs.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for providing beam switch latency using communications systems operating according to new radio (NR) technologies. For example, the method generally includes determining a latency associated with a beam switch from a source antenna array module to a target antenna array module when the target module is in a low power mode; and signaling a base station to use the determined latency after sending a command for the beam switch.

Abstract: Aspects of the disclosure relate to a method of operating a scheduled entity for wireless communication. In some aspects, the scheduled entity detects a fluctuation in a beam strength of at least one transmit beam from a scheduling entity. The scheduled entity transmits a first message to the scheduling entity, the first message indicating at least the fluctuation in the beam strength of the at least one transmit beam from the scheduling entity.

Abstract: Aspects of the present disclosure relate to receiver beamforming for serving and neighbor cell measurements. An exemplary method generally includes communicating with one or more base stations using a first beam type, initiating a transition to communicating with at least one of the one or more base stations using a second beam type in response to an indication of a trigger event, and communicating with the at least one of the one or more base stations using the second beam type.

Abstract: In some aspects, the present disclosure provides methods, apparatuses, and systems for efficient thermal mitigation while maintaining wireless device performance on a primary component carrier (PCC). Embodiments described may include implementation of target transceiver module configurations, where bandwidth (e.g., PCC bands and secondary component carrier (SCC) bands) may be monitored by a wireless device based on intra-module target configurations and/or inter-module target configurations. An intra-module target configuration may include a target transceiver module monitoring both PCC bands and SCC bands. An inter-module target configuration may include or refer to a plurality of target transceiver modules together monitoring PCC bands and SCC bands. In scenarios where operating temperatures exceed temperature thresholds, target transceiver module configurations may be implemented to transition PCC bands, SCC bands, or both, from a PCC-resident transceiver module to another transceiver module to reduce the operating temperatures of concern. Various additional and alternative aspects are described herein.

Abstract: A wireless communication device can expedite beam scans for beam management. The wireless communication device can perform a beam scan using a first beam reference signal of a synchronization signal block (SSB) and a second beam reference signal associated with a physical broadcast control channel (PBCH) of the SSB. For each synchronization signal block (SSB) index (e.g., transmit beam) monitored by the wireless communication device, the wireless communication device can obtain a respective beam quality metric on each of two or more respective receive beams using at least the first and second beam reference signals. Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. The method, systems, and devices may include techniques for establishing a first connection with a first cell operating in accordance with a first radio access technology (RAT), and performing a beam sweep procedure for one or more candidate beams for adding or handover to a second cell operating in accordance with millimeter wave (mmW) RAT. The beam sweep procedure may be performed based on previous beam measurements stored in a measurement database. The techniques may further include selecting a beam from the one or more candidate beams for adding or handover to the second cell based on the beam sweep procedure, and adding or handing over to the second cell by establishing a second connection with the second cell using the selected beam.
