Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish a first call associated with a first subscriber of the UE. The UE may establish a second call associated with a second subscriber of the UE, wherein the first subscriber and the second subscriber are active contemporaneously, and wherein the first call and the second call are associated with a first radio access technology (RAT). The UE may identify a mobility event that associated with an interruption to at least one of the first call and the second call, the mobility event involving switching the first subscriber to a second RAT. The UE may perform a mitigation action. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may establish, in a communication mode, a communication connection with a first radio access technology (RAT) or a second RAT. The UE may receive or identify an indication to deprioritize the first RAT. The UE may perform, based at least in part on the indication to deprioritize the first RAT, an action to deprioritize the first RAT, where the action is based at least in part in the communication mode. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may establish a communication connection with a serving cell associated with a first discontinuous reception (DRX) cycle configuration, determine, based at least in part on at least one of a first on duration of a first DRX cycle indicated by the first DRX cycle configuration or a type of traffic of one or more communications received during the first DRX cycle, an autonomous measurement gap associated with a neighboring cell, and perform a measurement of the neighboring cell during the autonomous measurement gap.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may detect a radio link failure between the UE and a master node of a dual-connectivity configuration. The UE may transmit, to a secondary node in the dual-connectivity configuration, an indication that the radio link failure has occurred. The secondary node may receive the indication of a radio link failure and transmit the indication of the radio link failure to the master node of the dual-connectivity configuration. The master node may identify a target node for the UE and perform a handover procedure of the UE from the master node to the target node.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for optimizing procedures to update a UE radio capability ID (URCID) when a UE moves to a new Public Land Mobile Network (PLMN) within a registration area. The techniques may help avoid unnecessary signaling traffic and reduce UE power consumption. An example method performed by a user equipment (UE) generally includes receiving at least one URCID assigned by a first PLMN; and taking one or more actions to delay or avoid updating the URCID when moving to a second PLMN in a same registration area as the first PLMN.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a combination of a first band and a second band, whether a measurement offset is to be applied for a neighbor measurement on the second band based at least in part on an estimated impact of interference from the first band on the second band; and selectively apply the measurement offset for the neighbor measurement based at least in part on whether the measurement offset is to be applied; or selectively report the measurement offset to a base station associated with the neighbor measurement based at least in part on whether the measurement offset is to be applied. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a network configuration procedure has failed a threshold number of times for a first radio access technology (RAT). The UE may perform a first action to prevent execution of the network configuration procedure until a timer has elapsed based at least in part on determining that the network configuration procedure has failed the threshold number of times. The first action may include transmitting a message that indicates that the UE does not have a capability to communicate using the first RAT, barring a cell or a tracking area of the first RAT or a second RAT that assists with establishing a radio access network connection for the first RAT, and/or refraining from reporting measurement results for the first RAT. Numerous other aspects are provided.

Abstract: Aspects presented herein enable updating the codebook configuration upon the changing of the cover or case of the UE. The apparatus applies a first codebook from a plurality of preconfigured codebooks. The apparatus detects a change of a cover state of the UE, wherein the change alters a transmission beam pattern at the UE. The apparatus applies a second codebook from the plurality of preconfigured codebooks based on the change of the cover state.

Abstract: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may camp on a cell of a first radio access technology (RAT). The UE may perform a cell search for a second RAT while camped on the cell of the first RAT, wherein the second RAT operates in a non-standalone mode with the first RAT. The UE may present, for display, an indication of whether the second RAT is available in the cell based at least in part on performing the cell search for the second RAT. Numerous other aspects are provided.
