Abstract: In a particular implementation, a method of wireless communication includes searching, at a user equipment (UE) having a first subscriber identity module (SIM) and a second SIM, transmit beams from a base station and receive beams from the UE to determine a subset of transmit beams. The method also includes storing indicators of the subset of transmit beams in a database accessible to the UE in response to the second SIM performing a particular operation that causes the first SIM to perform a tune away operation. The method further includes, after completion of the particular operation, performing measurement operations on the subset of transmit beams to select a particular transmit beam of the subset of transmit beams and a corresponding particular receive beam for attachment to the base station.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may measure a reference signal over a first subset of a set of measurement occasions using a serving UE receive beam according to a serving beam measurement periodicity. The UE may measure the reference signal over a second subset of the set of measurement occasions using a first subset of candidate UE receive beams of a set of candidate UE receive beams. The UE may measure the reference signal over a third subset of the set of measurement occasions using a second subset of candidate UE receive beams of the set of candidate UE receive beams. The UE may perform beam switching to a candidate UE receive beam of the set of candidate UE receive beams based at least in part on a result of measuring the reference signal.

Abstract: Example aspects include a method, apparatus and computer-readable medium of wireless communication at a user equipment (UE), comprising receiving, from a network device, a synchronization signal block (SSB) configuration scheduling a measurement window having a first duration. The aspects further include receiving, from the network device, at least one SSB during the first measurement window. Additionally, the aspects include selecting a second duration of the measurement window according to the at least one SSB. The second duration being shorter than the first duration.

Abstract: Methods, systems, and devices for wireless communications are described. Multiple reference signal occasions may occur during an inactive period of a discontinuous reception cycle configured for a wireless device. An amount of time the UE will be awake during the discontinuous reception cycle if the UE wakes up during a reference signal occasion of the multiple reference signal occasions may be determined for each of the reference signal occasions. The UE may wake up during the reference signal occasion associated with the shortest amount of awake time relative to the other reference signal occasions.

Abstract: In an aspect, the present disclosure includes a method, apparatus, and computer readable medium for wireless communications at a user equipment (UE) for measuring one or more synchronization signal block (SSB) beams from a network entity; selecting a highest rated SSB beam from the one or more SSB beams based on one or more selection factors; transmitting, to the network entity, a beam report including an identification of the highest rated SSB beam; initiating a timer in response to transmitting the beam report; determining whether a media access control (MAC) control element (CE) is received from the network entity before expiration of the timer; and performing beam switching from a current SSB beam to the highest rated SSB beam based on a determination that the MAC CE is not received from the network entity before expiration of the timer.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, relating to synchronization signal block (SSB) selection for paging occasions (POs). In an example, a UE may identifying a first SSB overlapping with or after a PO. The UE may further identify that a distance between the first SSB and the PO is less than a distance between a second SSB the PO, the second SSB located before the PO. The UE may further select the first SSB associated with loop operations based on identifying that the distance between the first SSB and the PO is less than a distance between the second SSB the PO.
