Abstract: A user equipment (UE) may use multiple subscriber identification modules (SIMs) in dual-SIM dual-active (DSDA) communications. The A DSDA UE may support identification of a set of available radio frequency (RF) resources for communications, where the set of available RF resources include multiple RF components (e.g., transmit/receive antennas), RF baseband resources (e.g., processing resources that support processing and decoding of transmissions), or combinations thereof. The set of available resources may be shared between multiple SIMS, and the UE may identify different resource partitions of the set of available resources, with different resource partitions used to provide concurrent communications of both the first SIM and the second SIM based on parameters of each SIM.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may perform, to a first base station and via a first radio frequency (RF) chain associated with a first subscription, a first uplink transmission based at least in part on one or more of an uplink carrier aggregation capability of the UE or an uplink multiple-input multiple-output (MIMO) capability of the UE. The UE may perform, to the first base station or to a second base station, and via a second RF chain associated with a second subscription and configured to operate simultaneously with the first RF chain, a second uplink transmission based at least in part on one or more of the uplink carrier aggregation capability of the UE or the uplink MIMO capability of the UE. Numerous other aspects are described.

Abstract: Methods, devices, and systems embodiments enable management of service preemption of at least one of a plurality of subscriptions that utilize a plurality of radio-frequency (RF) chains on a multi-Subscriber-Identity-Module, multi-active communication device in a manner that can accommodate a variety of different RF hardware components and configurations. Various embodiments provide methods implemented by a processor to manage service preemption. In response to detecting that a service of a second subscription initiated on a first RF chain is or will preempt a service of a first subscription that is also serviced by the first RF chain, the processor may determine whether there is a similar service on a second RF chain that may be used as a substitute for the first subscription's preempted service and, when available, the processor may configure the first subscription to begin utilizing the substitute service until the first RF chain is available.

Abstract: Methods, devices, and computer program products for antenna searching with antenna selection are disclosed. In one aspect, an apparatus operable in a wireless communication system includes a first receiver, a second receiver, and a processor. The first receiver receives a first signal including pilot signals from a first antenna. The second receiver receives a second signal including pilot signals from a second antenna. The processor, while a receive diversity is enabled, demodulates the first and second signals, determines whether a first condition is satisfied, and, in response to determining that the first condition is satisfied, searches for pilot signals via the second receiver and not the first receiver. The first condition is satisfied when a signal strength of the first signal does not exceed a first threshold and a signal strength of the second signal exceeds a second threshold.
