A MSIM UE may perform network operations for each network subscription. However, if the MSIM UE employs subscriptions for the same network, these operations may be performed redundantly. By notifying the network of multiple subscriptions at the UE and associating the multiple subscriptions at the network, the present invention provides power-saving at the UE and reduces network signaling overhead by optimizing communication for MSIM UE. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be configured to indicate to a network that the UE is associated with a plurality of network subscriptions, the plurality of network subscriptions including at least a first network subscription and a second network subscription, transmit location information using the first network subscription to the network, wherein the location information corresponds to a UE location, and receive data associated with the second subscription from the network.

A MSIM UE may perform various network operations for each network subscription. However, if the MSIM UE employs subscriptions for different network operators, the UE may need to periodically tune away for an active data transmission. Such tune-away may cause the UE to miss scheduled communications from the network. Aspects of the present invention are directed to a mechanism by which a UE can notify a base station of the MSIM state, and thereby allow the network to improve scheduling for the UE to allow for periodic tune-away by the UE with minimal impact on scheduled communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may by a UE, such as MSIM UE. The apparatus may be configured to determine that the UE is associated with one or more network subscriptions, and transmit a subscription indication to a network device, wherein the subscription indication identifies a subscription state of the UE to the network.

UE SIM state network notifications

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 based on the detecting, transmit to the first network, the second network or both a random access signal using a random access resource configured to convey a paging time adjustment request.

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.

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.

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.

Examples described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, determining collision between activities of the first subscription over a first RAT and activities of the second subscription over a second RAT and reselecting from the second RAT to a third RAT for the second subscription.

Aspects of the present disclosure provide an apparatus and methods for detecting and handling a spurious Dedicated Physical Channel (DPCH) of a cell in an active set from a mobile station side. A user equipment determines a signal-to-interference ratio (SIR) for each channel of a plurality of channels associated with cells maintained in an active set. A spurious DPCH has the lowest SIR among the plurality of channels. The user equipment puts the detected spurious DPCH in an exclusion mode in which the spurious DPCH is excluded from at least one of channel decoding or SIRE calculation, while maintaining the cell associated with the spurious DPCH in the active set.

Disclosed are methods and apparatus for rejecting unreliable downlink (DL) transmit power control (TPC) commands in windup mode. In one aspect, the method includes receiving by a user equipment (UE) a plurality of DLTPC commands from a base station, analyzing on one or more transmitted uplink (UL) TPC commands, detecting a windup mode based on the one or more DLTPC and ULTPC commands, and rejecting one or more DLTPC down commands in the windup mode.
