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: A system, apparatus and method to maintain continuity of a Voice over Long Term Evolution (LTE) (VoLTE) call. The system includes a first user equipment (UE) configured to perform a (VoLTE) call and a second UE configured to perform the VoLTE call with the first UE. The UE's are configured to maintain continuity of the VoLTE call by determining when one of a first dedicated bearer linked to a first default bearer of the first UE or a second dedicated bearer linked to a second default bearer of the second UE is lost and transmitting a signal to an Internet Protocol (IP) Multimedia Subsystem (IMS) server that prevents release of the determined dedicated bearer, the signal further triggering a re-activation of the determined dedicated bearer.

Abstract: A user equipment (UE) and corresponding methods to conserve power by the UE. The UE includes a transceiver, the transceiver configured to enable the UE to establish a connection with a Long Term Evolution (LTE) network and configured to operate using a Connected Discontinuous Reception (CDRX) functionality. The processor controls the transceiver by receiving an uplink (UL) grant at a first subframe of a frame of a cycle of the CDRX functionality, transmitting data based upon the UL grant at a predetermined second subframe, and receiving a response from the LTE network corresponding to one of an acknowledgement (ACK) and a negative ACK (NACK) at a predetermined third subframe. The processor deactivates the transmitter for a remainder of the frame based or deactivates a receiver for a remainder of the frame based upon whether the ACK is received.
