Abstract: Dynamic User Equipment (UE) beam switching for millimeter wave (mmWave) measurements in asynchronous networks is discussed in which a UE configured with a plurality of UE beams receives timing information of detected cells in an asynchronous network, and calculates, based on the timing information, a maximum offset for the detected cells indicating a timing difference between a pair of cells of the detected cells that is larger than a timing difference between any other pair of the detected cells. A UE beam switch from a UE beam to another UE beam of the plurality of beams is scheduled based on the maximum offset, which includes using the maximum offset to determine how often the UE beam switch can be performed. Other aspects and features are also claimed and described.

Abstract: A technique for performing AGC and DC compensation in a receiver. The receiver comprises an energy estimator for generating an estimate of the level of a received signal; an RF device to apply gain to the received signal; an AGC for controlling the RF device gain based on the energy estimation; a first DC compensation loop for finely adjusting the DC component of the received signal in fast or slow tracking mode (FTM or STM); and a second DC compensation loop for coarsely adjusting the DC component of the received signal. Three modes of AGC operations: In Acquisition, iterations of FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during signal timing detection. In Connected, long energy estimation, RF device gain adjustment, and STM fine and coarse DC adjustments are performed during superframe preamble. In Sleep, FTM fine DC adjustment, short energy estimation, and RF device gain adjustment are performed during superframe preamble.

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: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive, from a base station, an indication of a set of component carriers (CCs) for the UE and a respective frequency range (FR) for each CC of the set of CCs. Each CC-FR pairing may be associated with a respective priority of a set of priorities. The UE may initiate a plurality of timers, where each timer of the plurality of timers may correspond to a respective CC-FR pairing. After expiration of a timer of the plurality of timers, the UE may measure one or more reference signals of a subset of the set of CCs based at least in part on a capability of the UE and a priority of the respective CC-FR pairing associated with the timer.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may perform a set of synchronization signal block (SSB) measurements and select a serving UE beam and a set of candidate UE beams for measuring a channel state information (CSI) reference signal (CSI-RS) based on the set of SSB measurements. The UE may identify, or predict, time resources for the CSI-RS based on previous CSI-RS configurations. The UE may measure the CSI-RS based on the time resources using a candidate UE beam from the set of candidate UE beams. The UE may transmit, to an access network entity, a measurement report based on measuring the CSI-RS using the candidate UE beam or a last CSI-RS measurement on the serving UE beam.

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 UEis 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: Embodiments include methods that may be performed by a processor of a mobile device and a processor of a base station for managing beam failure recovery (BFR). The processor of the mobile device may determine whether a beam failure of a communication link with a base station has occurred, determine whether contention free random access (CFRA) resources have been configured in response to determining that a beam failure has occurred, and initiate contention based random access (CBRA) in response to determining that CFRA resources have not been configured. The processor of the base station may receive from the mobile device a message initiating CBRA, determine whether a downlink beam or quasi-colocation (QCL) assumption a downlink resource of a physical random access channel (PRACH) is different from any active downlink beam or QCL assumption, and perform CBRA with the mobile device.
