Abstract: Various aspects relate to acquisition of system information (SI). In some examples, a UE uses a guard timer to control how long the UE attempts to acquire a particular type of SI. In some examples, a UE that has entered a cell may determine whether there are any remaining paging occasions (e.g., that may indicate an SI update) during a period of time. If there is an insufficient number of paging occasions remaining (e.g., zero or one), the UE may monitor for broadcast SI. In some examples, after sending a request for SI to a base station, a UE may also periodically monitor for SI broadcast by the base station (e.g., to avoid potential delays in obtaining the SI). In some examples, if a UE does not acquire SI, the UE may use default SIB information (e.g., that expedites reselection to another cell).

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling for communications in a wireless communications system. The control signaling may indicate a first duration for an inactivity timer. The UE may initiate the inactivity timer and a second timer based on identifying a period of inactivity. The second timer may have a second duration that is shorter than the first duration for the inactivity timer. In some examples, the second duration may be based on one or more parameters, such as a display status, a battery status, a scaling factor, the first duration, an application state, or any combination thereof. The UE may release a connection for the communications in the wireless communications system based on an expiration of the second timer, an expiration of the inactivity timer, or a combination thereof.

Abstract: This disclosure provides systems, methods and apparatus, and computer programs encoded on computer storage media, for managing communications with a base station by a processor of a wireless device. In one aspect, a processor of a wireless device may receive from the base station a system information change indication in first system information. The processor may determine from the first system information scheduling information of second system information. The processor may determine a factor that a request for the second system information will collide with a request from another wireless device for the second system information. The processor may send the request for the second system information using the determined factor.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for reducing user equipment (UE) capability information message size. A method for wireless communications by a UE is provided. The UE sends a first UE capability information message to a base station (BS) including a first set of UE capability information. The UE sends at least a second UE capability information message to the BS subsequent to sending the first UE capability information message including a second set of UE capability information. The second set of UE capability information does not include one or more UE capabilities included in the first set of UE capability information. The BS receives the first and second UE capability information.

The wireless communication device reselects a second cell for camping in response to a failure to receive the first system information. The second cell is associated with the wireless communication network and different from the first cell. The wireless communication device maintains the network session during the reselecting the first cell for camping and the reselecting the second cell for camping.

Abstract: A user equipment (UE) expedites cell reselection. In one instance, the UE starts a reselection timer for reselecting to a neighbor cell when a signal quality of a serving cell is determined to fall below a first threshold. The UE then expedites reselecting to the neighbor cell based on a difference between the signal quality of the serving cell and the signal quality of the neighbor cell when the signal quality of the serving cell falls below a second threshold.

Abstract: Methods and devices for implementing dynamic receive mode management to improve data throughput and paging performance on a multi-subscriber identification module (SIM) wireless communication device may include detecting, on a protocol stack associated with a first SIM, an active communication in a first network, detecting, on a protocol stack associated with a second SIM, an idle mode paging cycle in a second network, prompting entry into a selected dual receive mode on the shared RF resource, and monitoring at least one performance metric for the idle mode paging cycle associated with the second SIM while in the dual receive mode. Based on the monitored performance metric while in the dual receive mode, the wireless communication device may determine whether paging performance is degraded for the second SIM, and if so, trigger entry into a fallback mode on the shared RF resource.

Abstract: Methods, systems, and devices for wireless communications are described. For example, the described techniques provide for a user equipment (UE) to predict a gain state for an initial acquisition procedure. For example, the UE may use a machine learning (ML) model to predict an initial gain state which is likely to result in a successful initial acquisition procedure (e.g., without adjusting the gain state and reattempting the initial acquisition procedure). The UE may input UE history data or crowdsourced data (e.g., from a local network or a cloud-based server) into the ML model to generate a predicted gain state which may be more likely to result in a successful initial acquisition (e.g., without reattempting the initial acquisition procedure). The UE may use the initial gain state generated by the ML model to attempt an initial acquisition procedure with a network entity.
