Abstract:
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.
