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.
