Abstract: Wireless communication techniques for antenna-switched diversity and multi-SIM concurrent operation management are discussed. A UE may communicate via a transmission path associated with a first subscriber identification module (SIM). The transmission path may be mapped to one of a first one or more antennas in accordance with a determination as to whether the UE supports at least one of frequency-division duplex (FDD) antenna-switched diversity or time-division duplex (TDD) antenna-switched diversity when concurrently performing wireless communication associated with the first SIM and wireless communication associated with a second SIM. The UE may also communicate via at least one reception path associated with the second SIM. The at least one reception path may be mapped to a second one or more antennas in accordance with the determination as to whether the UE supports at least one of FDD antenna-switched diversity or TDD antenna-switched diversity.

Abstract: Methods and apparatuses are presented for acquiring a wireless system by a multi-subscriber identity module (SIM) user equipment (UE). For example, an example method for acquiring a wireless system is presented that includes conducting, by a first subscription corresponding to a first SIM of the UE, a call using a shared radio resource of the UE. In addition, the example method may include predicting, upon completion of the call, a pilot timing error and a frequency error associated with a pilot signal of a network associated with a second subscription corresponding to a second SIM of the UE. In addition, the example method may include attempting to acquire the pilot signal based on the pilot timing error and the frequency error. As such, the example method may allow the multi-SIM UE to more quickly acquire a wireless system relative to legacy methods. Other aspects, embodiments, and features are also claimed and described.

Abstract: Systems, methods, apparatuses, and media are provided for use of multi-RAT user equipment. Communication may be performed using a first radio access technology on a first transceiver. A diversity receiver may be used to provide spatial diversity for the communication using the first radio access technology. Use of the diversity receiver to provide spatial diversity for the communication using the first radio access technology may be stopped. Use of the diversity receiver to communicate using a second radio access technology may be started, with the communication using the first radio access technology continuing on the first transceiver.
