Abstract

Embodiments include systems and methods for managing cell selection performed in a multi-subscription multi-standby communication device. A device processor may operate the multi-subscription multi-standby communication device in a full concurrency mode in communication with a first cell and a second cell. The device processor may determine whether a detected third cell supports operation of the multi-subscription multi-standby communication device in the full concurrency mode. The device processor may perform cell reselection to the detected third cell in response to determining that the detected third cell supports operation of the multi-subscription multi-standby communication device in the full concurrency mode.

Description

Background technique [0001] A Multiple Subscription Multiple Standby (MSMS) communication device may include two or more Subscriber Identity Module (SIM) cards, each associated with a different service provider subscription. A multi-subscription, multi-standby communications device may be provided in a range of configurations, including a dual-subscription, dual-standby (DSDS) configuration in which two SIMs share a set of receive (Rx) circuitry (referred to as an "Rx chain"). "). A multi-subscription, multi-standby communication device may also be configured to use various radio access technology (RAT) protocols (eg, 3GPP Long Term Evolution (LTE), Global System for Mobile (GSM), and Wideband Code Division Multiple Access, WCDMA). [0002] A multi-subscription, multi-standby communication device may be configured as a dual receive (DR) device (DR-MSMS), wherein the multi-subscription, multi-standby communication device has a set of transmit (Tx) circuits (referred to as a "T...
