Abstract: Aspects described herein relate to using antenna-switched diversity (ASDIV) in wireless communications. A serving node can be communicated with using a serving radio access technology (RAT) and based on an ASDIV configuration, wherein the ASDIV configuration defines an antenna switching configuration including a state of one or more switches in an ASDIV switch group for switching between one or more antennas for the communicating based on sensing one or more parameters of the communicating. It can be determined whether a target RAT supports operating using a same ASDIV switch group as the serving RAT. A target node can be communicated with using the target RAT and based on the ASDIV configuration where the target RAT operates using the same ASDIV switch group as the serving RAT.

Abstract: The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a multilayer perceptron neural network with Hammerstein structure by dividing an aggressor signal into real and imaginary components, augmenting the components by weight factors, executing a linear combination of the augmented components, and executing a nonlinear sigmoid function for the combined components at a hidden layer of multilayer perceptron neural network to produce a hidden layer output signal. At an output layer, hidden layer output signals may be augmented by weight factors, and the augmented hidden layer output signals may be linearly combined to produce real and imaginary components of an estimated jammer signal. A linear filter function may be executed for the components of the jammer signal, and to produce a nonlinear interference estimate used to cancel the nonlinear interference of a victim signal.

Abstract: Various embodiments leverage the typical manner in which a RAT selects a supported frequency band listed in its acquisition database and the standard communications with its network indicating the supported frequency bands to avoid potential coexistence events with one or more other RATs. In particular, various embodiments include methods for avoiding band interference between RATs operating on a multi-SIM communication device by identifying the frequency bands available to each of the RATs, comparing the identified frequency bands to determine whether any RAT's frequency bands will interfere with one or more other RAT's frequency bands, and in response to determining that there is a possibility of frequency band interference, removing those interfering frequency bands from that RAT's acquisition database. As a result, during standard communications, that RAT will report to its network that it supports only non-interfering frequency bands.

Abstract: A system, a method and an apparatus are described. The apparatus includes a modem that responds to a thermal mitigation request by invoking different levels of thermal mitigation for different concurrently active connections. In some instances, the modem may invoke thermal mitigation with respect to a first active connection and refrain from invoking thermal mitigation with respect to a second active connection maintained by the modem. The apparatus determines the first and second active connections based on subscriptions corresponding to subscriber identification modules, an identification of a power amplifier or group of power amplifiers responsible for a thermal issue in the modem. The selection of mitigation levels for each active connection and decisions to invoke mitigation on one connection while refraining from invoking mitigation on another connection may be based on priorities of the active connections, including quality of service related priorities.

Abstract: Mobility management is described for simultaneous, multiple radio access technology (RAT) user equipments (UEs). When the UE detects a mobility event that would trigger transfer of a communication service from a first RAT to a second RAT, the UE determines whether there is an existing connection to a base station of the second RAT and uses cached measurement information related to this base station to influence or weight how the transfer is performed/handled/managed.
