Abstract: Methods and apparatuses are presented for managing a multi-subscriber identity module (SIM) user equipment (UE) such that a camp-on procedure of one or more subscriptions of the multi-SIM UE may be more quickly implemented. For example, a method is presented that includes receiving, by a first subscription corresponding to a first SIM of the multi-SIM UE, a system information block (SIB) from a cell, wherein the SIB includes information associated with the cell and each of one or more neighbor cells of the cell. Additionally, the example method may include selecting from the cell and the one or more neighbor cells and based on the information included in the SIB, a target cell upon which a second subscription of the multi-SIM UE is to camp. Moreover, the example method presented by the present disclosure may include camping the second subscription on the neighbor cell.

Abstract: The present disclosure presents a method and an apparatus reducing call set up failures at a user equipment (UE) during serving radio network subsystem (SRNS) relocation. For example,the apparatus and method may include identifying that a second circuit switched (CS) or packet switched (PS) call is initiated at the UE when a first CS or PS call is in progress at the UE, determining that a SRNS relocation is triggered at a network entity that is in communication with the UE prior to setting up of a radio access bearer (RAB) for the second CS or PS call, and terminating the SRNS relocation and sending a failure message to the network entity in response to the determination. As such, reduced call set up failures at the user equipment (UE) during SRNS relocation may be achieved.

Abstract: A method for wireless communication in a multi-antenna user equipment (UE) is described. The UE comprises communicating with a network device using a first antenna; assessing communication metrics; comparing the communication metrics to a threshold; determining to switch from the first antenna to a second antenna for communicating with the network device based at least in part on the comparing the communication metrics to the threshold; determining a switch duration corresponding to a length of time to switch from the first antenna to the second antenna for communicating with the network device; determining a silence window in which communication with the network device is suspended; determining a silence duration corresponding to a length of time of the silence window; comparing the switch duration to the silence duration; and switching from the first antenna to the second antenna during the silence window in response to the silence duration being equal to or greater than the switch duration. Further, a corresponding UE is described.
