    Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may receive link capability information from a second UE that has a cellular wireless connection with a network entity of a cellular wireless network. The link capability information may be associated with a subscription of the second UE to the cellular wireless network. The first UE may establish a local wireless connection with the second UE based on the link capability information associated with the subscription of the second UE to the cellular wireless network. The first UE may communicate one or more messages with the network entity of the cellular wireless network via the second UE using first subscriber identity module (SIM) credentials of the first UE or second SIM credentials of the second UE based on establishing the local wireless connection with the second UE.

    Abstract: Methods, systems, and devices are described for identifying and mitigating in-device coexistence interference for multicarrier systems implementing soft combining decoding techniques. In some aspects, the described techniques include identifying time-frequency resources of a received signal subject to coexistence interference at a transceiver of a wireless device. The time-frequency resources may include, for example, symbols, slots, code-blocks, sub-frames, subcarriers, etc. Resource-specific mitigation may then be applied to the identified resources, for example, including skipping or nulling the interfered resources in the time domain, frequency domain, or both. In some aspects, the resource-specific mitigation may be performed at the soft-combining stage of the decoding process, such as by skipping or nulling one or more log likelihood ratio (LLR) instances that correspond to the interfered resource(s).

    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 and devices are disclosed for implementing opportunistic mobile receive diversity (“OMRD”) on a multi-SIM wireless device. The wireless device may receive a request from a protocol stack associated with the first SIM to utilize the second RF resource for receive diversity, and determine whether a protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM. Upon determining that the protocol stack associated with the second SIM currently has a lower priority than the protocol stack associated with the first SIM, the wireless device may grant control of the second RF resource to the protocol stack associated with the first SIM. Granting control may provide, to the protocol stack associated with the first SIM, a capability to enable and disable receive diversity using the first and second RF resources.

    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.

    Abstract: Aspects relate to wireless communication at a wireless communication device. The wireless communication device may include a transmitter configured to communicate using a first communication protocol, a receiver configured to communicate using a second communication protocol, different from the first communication protocol, a first antenna coupled to the transmitter, a second antenna coupled to the receiver and physically separated from the first antenna by a variable distance. The wireless communication device transmits, via the first antenna, a first transmission within a first frequency range, and receives via the second antenna, a second transmission within a second frequency range that overlaps the first frequency range. To receive the second transmission, the device may perform a radio frequency coexistence mitigation procedure based on the variable distance between the first antenna and the second antenna in response to detection of a concurrency in time between the first transmission and the second transmission.
