The UE may identify that the length of time satisfies a threshold. The UE may configure the one or more RF chains to the first RAT. The UE may initiate a beam measurement on the first RAT in a number of consecutive measurement occasions based at least in part on the length of time satisfying the threshold. Numerous other aspects are described.

Techniques for beam management during a tune-away

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, using a first subscription of the UE, a first communication connection associated with a first service. The UE may establish, using a second subscription of the UE, a second communication connection associated with a second service. The UE may operate in a dual subscriber identity module (SIM) dual active (DSDA) mode based at least in part on establishing the first communication connection and establishing the second communication connection. The UE may perform an action to maintain concurrent services, including the first service and the second service, while operating in the DSDA mode. Numerous other aspects are described.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a multi-subscriber identity module (SIM) user equipment (UE) may communicate, using a first SIM, on a plurality of component carriers. The multi-SIM UE may select a first subset of component carriers from the plurality of component carriers based at least in part on a component carrier prioritization. The multi-SIM UE may identify an amount of memory available to a second SIM. The multi-SIM UE may tune away, based at least in part on the amount of memory available to the second SIM, from a second subset of component carriers The first subset of component carriers may be different from the second subset of component carriers. Numerous other aspects are described.

Techniques for carrier prioritization in multi-subscriber identity module features

Aspects of the present disclosure provide wireless communication devices and methods configured to operate with multiple active connections. A user equipment establishes a first active connection associated with a first subscription. The user equipment also establishes a second active connection, simultaneous to the first active connection, associated with a second subscription. The user equipment provides modem information corresponding to connection qualities of the first active connection and second active connection, to an operating system of the user equipment. Furthermore, the user equipment mitigates contention between the first active connection and second active connection by degrading at least one of the first active connection or second active connection in accordance with a decision given by the operating system based on the modem information.

Modem assisted contention handling of multiple active connections in wireless communications

Aspects described herein relate to communicating, based on a first subscription, with a first Radio Access Technology (RAT) over a bandwidth part (BWP) in a set of one or more configured BWPs, tuning a transceiver away from the BWP to a second frequency to communicate, based on a second subscription, with a second RAT for a period of time, tuning, after the period of time, the transceiver back to a selected BWP to communicate with the first RAT, and handling BWP parameters during or based on the tune away or tune back.

Techniques for configuring bandwidth parts for multiple-subscription communication devices

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a plurality of beams, from a base station, wherein the plurality of beams are associated with a corresponding plurality of monitoring occasions for a first subscription of the UE. The UE may determine whether a monitoring occasion for a second subscription of the UE collides with one or more of the plurality of monitoring occasions, for the first subscription of the UE, corresponding with the plurality of beams. The UE may transmit, to the base station, an indication of a selected beam, from the plurality of beams, based at least in part on the measuring and the determining. Numerous other aspects are provided.

Beam selection in idle mode to avoid monitoring occasion collision

A method, a computer-readable medium, and an apparatus may be a User Equipment (UE) having a first subscription to a first RAT and a second subscription to a second RAT configured to operate using the first RAT, to change from operating using the first RAT to operating using the second RAT to monitor multiple Synchronization Signal Blocks (SSBs) at multiple times prior to performing at least one of decoding a paging message, receiving system information, searching a neighboring frequency, or measuring the neighboring frequency, to return to using the first RAT during a first period between at least one set of adjacent times of the multiple times that the UE monitors for the SSBs, and to change from using the first RAT to using the second RAT to receive the paging message, receive the system information, search the neighboring frequency, or measure the neighboring frequency.

Quick burst tuneaway

A user equipment may, based on a tuneaway, start suspend a first timer and/or deactivate a first counter and may, based on a tuneback, resume the first timer and/or activate the first counter. The first timer and first counter may be configured to be used to determine that a sufficiently large number of sufficiently closely timed beam failure indications have been received and, in response to that determination, initiate an access procedure. A user equipment may also identify an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap and may, based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modify the timing of the at least one radio access technology event or the timing of the tuneaway gap.

Systems and methods for wireless communication

Methods, systems, and devices for wireless communication are described. Some wireless devices (e.g., dual subscriber identity modules (SIM) devices) may support two subscriptions such that while one subscription is actively transmitting or receiving, the other subscription is put on standby. The wireless device may identify collisions in time between monitored paging messages associated with the first and second subscriptions. Accordingly, the wireless device may modify a radio access technology (RAT) priority setting for one of the subscriptions, such that paging messages may be received via a RAT different that the RAT used for the other subscription (e.g., following a cell reselection procedure performed according to the modified RAT priority). Operation using a modified RAT priority setting may be referred to as a fallback mode, which may be exited upon expiration of a timer. Additionally, discontinuous reception (DRX) durations associated with the RATs used for subscription paging may be reduced.

Mitigating page collisions in dual subscriber identity module devices

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.

Enhancing data performance in multi-subscriber identity module (SIM) wireless communication devices

Aspects of the present disclosure are directed to improving maximum transmit power in multi-carrier reverse-link transmission. In one aspect, a method of carrier management for a multi-carrier reverse link transmission is disclosed. A method can include transmitting a reverse link signal on a plurality of carriers, and the reverse link signal including payload data and overhead data. A method can funnel payload data onto a first carrier of the plurality of carriers, while maintaining transmission of the overhead data on all the carriers of the plurality of carriers. Other aspects, embodiments, and features are also claimed and described.
