Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) comprising a plurality of symbols. The UE may obtain, during a plurality of measurement windows, a plurality of measurements associated with a beam group of a plurality of reception beams corresponding to a plurality of symbols of the SSB, wherein the beam group is associated with a serving cell and comprises a first set of beams and a second set of beams, wherein each beam of the beam group corresponds to a measurement window having a window size that is less than a size of a corresponding symbol of the plurality of symbols of the SSB. The UE may perform a wireless communication task based on the plurality of measurements. Numerous other aspects are described.

Abstract: A UE may be configured to select narrower or wider beams that may be suitable for use with a current UE mobility, scattering environment, etc. The UE may track changes to an identified beam of a certain width, and so may recover from tracking or other radio link failures by switching to a beam that is spatially adjacent or to a beam of a different width. The UE may identify a first beam associated with a first beam width based on at least one reference signal received by the UE. The UE may further determine a set of beams based on the first beam width that is associated with the identified first beam, and the determined set of beams may include at least one beam corresponding to the first beam width. The UE may further measure respective channel qualities associated with each beam of the determined set of beams.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.

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: Wireless communications systems and methods related to monitoring and/or measuring synchronization signal blocks (SSBs) in one or more beam directions based on timing offsets associated with the beam directions are provided. In some aspects, a method of wireless communication performed by a user equipment (UE) includes: receiving, from a wireless communication device, a synchronization signal block (SSB); and measuring, based on timing offsets for each of a plurality of beams of the SSB, one or multiple beams of the SSB. In some instances, the UE determines a number of beams of the SSB to measure based on the timing offsets for each of the plurality of beams of the SSB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure, using one or more receive beams, a channel state information reference signal (CSI-RS) transmitted on a transmit beam of the CSI-RS according to a beam management configuration for periodic CSI-RSs, where the UE performs measurements according to a static beam sweeping schedule or a dynamic beam sweeping schedule associated with the transmit beam of the CSI-RS based at least in part on the beam management configuration. In some aspects, the UE may transmit a measurement report indicating one or more measurements of the CSI-RS based at least in part on measuring the CSI-RS. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for adaptively updating one or more parameters, such as power hysteresis, for determining whether beam switching should be performed. A user equipment (UE) may assess a first beam quality of a first beam for communications with a network entity and a second beam quality of a second beam. The UE adjusts a value of power hysteresis based on one or more conditions, such as whether the UE is mobile and/or the signal to noise ratio (SNR) of the first beam is less than a threshold. Based on the adjusted value of power hysteresis, the UE may switch from the first beam to the second beam if a difference between the second beam quality and the first beam quality is greater than the adjusted value of power hysteresis.
