摘要： Methods, systems, and devices for wireless communication are described in relation to a Multiple Subscriber Identify Module (MSIM) user equipment (UE). The UE associated with multiple network subscriptions may determine a first timing of a first set of paging occasions associated with a first network subscription of the multiple network subscriptions, wherein the first network subscription is associated with a first network; determine a second timing of a second set of paging occasions associated with a second network subscription of the multiple network subscriptions, wherein the second network subscription is associated with a second network; compare the first timing and the second timing; detect a paging time adjustment condition based on the comparing; and transmit, based on detecting the paging time adjustment condition, a paging frame offset adjustment request to the first network, the second network or both.

摘要： Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a wireless communication device may determine, in a particular state, that a wireless communication device is performing a connection establishment procedure. The wireless communication device may refrain from transferring from a first radio access technology (RAT) to a second RAT until completing the connection establishment procedure. The second RAT may satisfy a set of transfer criteria associated with performing a transfer from the first RAT to the second RAT.

摘要： Methods, systems, and devices are described for enhanced power savings in wireless devices through mobile initiated dormancy procedure. A user equipment (UE) may establish radio resource control (RRC) connectivity with a base station of the network, and transmit and receive one or more distinct signaling messages for dormancy state initialization and suspension at the UE. Dormancy state implementation at the UE may conserve available power resources at the UE during periods of inactive data transaction. The one or more signaling messages may contain a single or multi-bit indication for the receiving device, and may be transmitted via direct signaling on upper layer protocols of the data network or mapped to allocated resources of a data transmission. The signaling messages may sustain synchronization between the interpreted functional mode of the UE at the base station and the implemented mode at the UE.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first set of synchronization signal blocks (SSBs) for a first subscription of the UE and a second set of SSBs for a second subscription of the UE; select a first SSB, from the first set of SSBs, for communications of the first subscription; identify a third set of SSBs by modifying the second set of SSBs to remove one or more SSBs from the second set of SSBs, at least one SSB of the one or more SSBs overlapping in time with the first SSB; select a second SSB from the third set of SSBs; and monitor the second SSB for paging messages of the second subscription. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine location information regarding the UE; and activate a receive beam of the UE in at least one symbol, associated with at least one transmit beam of at least one base station, based at least in part on the location information, wherein the UE is configured to activate the receive beam based at least in part on mapping information, at least partially determined by the UE, that indicates that the receive beam is associated with the location information. Numerous other aspects are provided.

摘要： Methods, systems, and devices for wireless communications are described that provide for call continuity following radio link failure (RLF) through re-establishment of a voice call using a same or different radio access technology (RAT) before the call is dropped. Upon detection of RLF on a connection supporting a voice call, a UE may initiate a drop call timer and scan for available connections. The voice call may be attempted to be re-established if a connection is available on using a RAT of an existing connection. The voice call in such cases may continue without the call being dropped. Upon expiration of the drop call timer, the UE may attempt to establish a connection using a RAT identified during the duration of the drop call timer.

摘要： A multi-SIM UE may perform network SIB acquisition for each network subscription. However, if the multi-SIM UE employs subscriptions for the same network these operations may be performed redundantly. By identifying that the UE is employing multiple subscriptions, the UE and network can perform a single SIB acquisition for multiple subscriptions, which reduces power consumption and optimize network signaling overhead. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to determine that the UE is associated with a plurality of network subscriptions, the plurality of network subscriptions being associated with a network, select a network subscription from the plurality of network subscriptions, perform a random-access procedure using the network subscription, receive system information broadcast in response to the random-access procedure, and configure the plurality of network subscriptions at the UE based on the system information.
