Abstract: Apparatus and methods to support parallel communication using multiple subscriber identities in a wireless communication device via multiple subscriber identity modules (SIMs) are disclosed. A representative method includes establishing a connection with a first wireless network via a first wireless cellular protocol software stack for a first subscriber identity associated with a first subscriber identity module; registering with a second wireless network via a second wireless cellular protocol software stack for a second subscriber identity associated with a second subscriber identity module; and receiving radio frequency signals from the second wireless network via the second wireless cellular protocol software stack in parallel with communicating with the first wireless network via the first wireless cellular protocol software stack. The first and second wireless cellular protocol software stacks share at least a portion of radio frequency wireless circuitry for communicating with the first and second wireless network respectively.

Abstract: A user equipment and a method performed by the user equipment. The user equipment includes a transceiver configured to enable the user equipment to establish a connection with a first network and a second network, the first network configured to provide signals to control a transmit power of the transceiver and a processor configured to control the transmit power of the transceiver. The processor controls the transmit power by determining at least one network operation of the user equipment, the network operation associated with a configuration of the connection with the LTE network, receiving a signal from the LTE network indicating an increase in the transmit power to be used and performing a power operation that adjusts the transmit power of the transceiver less than the increase indicated in the signal.

Abstract: Methods, apparatuses and computer readable media are described that configure wireless circuitry of a wireless communication device. The wireless communication device establishes a connection to a first wireless network using first and second receiving signaling chains. In response to detecting a radio frequency tune-away event, the wireless communication device reconfigures only one of the radio frequency signaling chains to receive signals from a second wireless network when a set of receive signal conditions for the second wireless network is satisfied. The wireless communication device reconfigures both of the radio frequency signaling chains to the second wireless network when the set of receive signal conditions is not satisfied.

Abstract: Methods, apparatuses and computer readable media are described that determine a connection state between a mobile wireless device and a wireless network upon detection of an interruption of a connection between the mobile wireless device and the wireless network. The mobile wireless device transmits an uplink resource allocation message to the wireless network, and when receiving no response to the uplink resource allocation message, transmits a random access message to the wireless network. When receiving no response from the wireless network to the random access message, the mobile wireless device executes a radio link failure procedure. In an embodiment, the uplink resource allocation message includes a unique identifier for an existing radio resource control connection between the mobile wireless device and the wireless network.
