Abstract

An apparatus for wireless communication is provided. The apparatus is configured to obtain, based on a first mobile alert associated with a first subscriber identity module (SIM) being scheduled for broadcast from a first network, an indication of receiver resources assigned for receiving the first mobile alert associated with the first SIM. The apparatus is further configured to refrain, based at least in part on the indication, from receiving a second mobile alert associated with a second SIM scheduled for broadcast from a second network. The first mobile alert and the second mobile alert may be associated with messages from at least one of a CMAS or an ETWS.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a divisional application of U.S. patent application Ser. No. 17/302,317, entitled ALERT AND WARNING MESSAGE PROTECTION IN MSIM,” and filed on Apr. 29, 2021, which claims the priority of U.S. Provisional Application Ser. No. 63/030,814, entitled “ALERT AND WARNING MESSAGE PROTECTION IN MSIM” and filed on May 27, 2020, of which are expressly incorporated by reference herein in their entirety. BACKGROUND Technical Field The present disclosure relates generally to communication systems, and more particularly, to alert/warning message protection in multi subscriber identity (or identification) module (SIM) (MSIM). Introduction Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems. These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate on a municipal, national, regional, and even global level. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of a continuous mobile broadband evolution promulgated by Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with Internet of Things (IoT)), and other requirements. 5G NR includes services associated with enhanced mobile broadband (eMBB), massive machine type communications (mMTC), and ultra-reliable low latency communications (URLLC). Some aspects of 5G NR may be based on the 4G Long Term Evolution (LTE) standard. There exists a need for further improvements in 5G NR technology. These improvements may also be applicable to other multi-access technologies and the telecommunication standards that employ these technologies. SUMMARY The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later. A UE that utilizes a single receiver for receiving alert/warning messages from a plurality of SIMs may lose some or all of the alert/warning messages in some circumstances. Accordingly, there is a need for alert/warning message protection in MSIM. Different configurations/approaches are provided infra, including a first-come, first-served (FCFS) approach, an application processor (AP) trigger approach, a message stitching approach, and a single SIM (SSIM) approach. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE, and specifically a cellular baseband processor/modem of the UE. The apparatus is configured to obtain, based on a first mobile alert associated with a first subscriber identity module (SIM) being scheduled for broadcast from a first network, an indication of receiver resources assigned for receiving the first mobile alert associated with the first SIM. The apparatus is further configured to refrain, based at least in part on the indication, from receiving a second mobile alert associated with a second SIM scheduled for broadcast from a second network. In one configuration, to obtain the indication of the receiver resources being assigned for receiving the first mobile alert associated with the first SIM, the apparatus is configured to lock a transceiver resource management (TRM) module from requesting the receiver resources for receiving mobile alerts associated with other SIMs other than the first SIM. In one configuration, the first mobile alert and the second mobile alert are associated with messages from at least one of a commercial mobile alert system (CMAS) or an earthquake and tsunami warning system (ETWS). In one configuration, the apparatus is further configured to obtain, upon completion of the receiving the first mobile alert, a second indication that the receiver resources are unassigned for receiving mobile alerts associated with the first SIM. In one configuration, to obtain the second indication of the receiver resources b
