Abstract: Methods and apparatus for beam management where a beam is selected based on an estimated channel correlation matrix. The apparatus determines a channel correlation matrix based on downlink SSB reference signal received at the UE. The apparatus estimates a RSRP of a plurality of beams associated with an uplink channel based on the channel correlation matrix and associated beam weights. The apparatus selects a first beam from the plurality of beams having a highest estimated RSRP for communication with a base station. The apparatus communicates with the base station via the first beam.

Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a user equipment (UE). According to certain aspects, a UE may be configured to detect, in a first bandwidth part (BWP), a condition triggering a mobility procedure that involves a physical random access channel (PRACH) transmission in a second BWP, determining a timeline for transmitting the PRACH in the second BWP, based on a mobility procedure delay that accounts for BWP switching time for switching from the first BWP to the second BWP, and transmitting the PRACH in the second BWP in accordance with the timeline.

Abstract: A method of wireless communication by a user equipment (UE) includes determining a first synchronization signal block (SSB) to monitor beam management. The first SSB comprises a primary synchronization signal (PSS), multiple physical broadcast channels (PBCHs), and a secondary synchronization signal (SSS). The method also includes determining a list of receive beams for measuring the first SSB. The method further includes measuring the first SSB by measuring the PSS with a first beam from the list of receive beams, measuring, with a second beam from the list of receive beams, a first demodulation reference signal (DMRS) on a first PBCH symbol of a first of the PBCHs, measuring the SSS with a third beam from the list of receive beams; and measuring, with a fourth beam from the list of receive beams, a second DMRS on a second PBCH symbol of a second of the PBCHs.

Abstract: Techniques for managing base station beam panic for new radio technologies may include a user equipment (UE) measuring a signal quality of a serving beam from a base station. The UE may determine the signal quality has decreased by at least a threshold amount, and enable a signal panic operation to search for a beam different from the serving beam, in response to the signal quality decreasing by at least the threshold amount.

Abstract: Aspects of the disclosure relate to a user equipment (UE) configured to schedule resource management procedures including measurements and tracking loop procedures. In some examples, the UE includes at least one antenna pair and two or more receivers. The UE may be configured to determine a plurality of combinations of antenna pairs and component carriers, where each component carrier is associated with a particular frequency. The UE may further be configured to schedule measurements/tracking loop procedures to available receivers first and utilize a selection algorithm to select combinations of antenna pairs and component carriers and map the selected combinations to the remaining of the available receivers to perform tracking loop procedures. Other aspects, features, and embodiments are also claimed and described.

Abstract: Methods, systems, apparatuses, and devices are described for transmitting a measurement report during wireless communications. When, for example, a low-power period (e.g., CDRX OFF period) is scheduled to begin during a time defined by a measurement event timer (TTT timer), a UE may modify the low-power period. The low-power period may be modified based, at least in part on determining the low-power period of the UE will begin during a time defined by a measurement event timer, a duration of the measurement event timer, and a duration of the low-power period. Modifying the low-power period may include delaying the start of the low-power state until after transmission of the MR associated with the measurement event timer or skipping the low-power period altogether. The UE may transmit the MR based, at least in part, on the modification.
