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: Certain aspects of the present disclosure provide a method for wireless communications by a user equipment (UE), generally including receiving assistance information, from a network entity, indicating a mapping between beams across different remote radio heads (RRHs) and using the assistance information to perform beam management when the UE is moving from the coverage area of one RRH to the coverage area of another RRH.

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: Wireless communications systems and methods related to wireless communications in a system are provided. A user equipment (UE) may determine a plurality of antenna configurations for a plurality of channel frequencies. The UE may determine a set of signal strengths for at least one beam received at one or more antenna configurations of the plurality of antenna configurations for at least one of the channel frequencies. The UE may select, based on the set of signal strengths, a first antenna configuration of the plurality of antenna configurations. After selection of the first antenna configuration, the UE may communicate with a base station, in one or more channel frequencies based on the first antenna configuration.

Abstract: Apparatus, methods, and computer-readable media for facilitating multi-tasking and smart location selection during connected-mode discontinuous reception (CDRX) mode are disclosed herein. Example techniques disclosed herein enable a UE to perform multiple tasks during a same SSBS to reduce the number of wake-up SSBSs. For example, disclosed techniques enable a UE to perform RLM tasks and loop tracking tasks during a first SSBS and thereby reduce the number of wake-up SSBSs. In some examples, the UE may also perform the search task or the measurement task during the same first SSBS and, thereby, further reduce the number of wake-up SSBSs. Example techniques disclosed herein may also enable the UE to select which SSBS occurrences to wake-up for during the OFF duration of the CDRX cycle.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a measurement procedure for beam detection within an existing cell. The UE perform a search procedure for a first synchronization signal block (SSB) to detect a first beam of a base station. The UE may determine a first timing offset for the first SSB based on the search procedure. The UE may estimate a second timing offset for a second SSB from the base station based on the first timing offset. The UE may perform a measurement procedure for the second SSB to detect a second beam of the base station based on the second timing offset. The UE may prune fake beams based on synchronization signals used for the measurement procedure.
