Abstract
A method for facilitating synchronization between a communications network (102) and a wireless communications device (104, 106, 200) operating in a Continuous Packet Connectivity, CPC, discontinuous transmission, DTX, mode, comprises monitoring (304) at the wireless communications device (104, 106, 200) the radio conditions of downlink communications using control bits received from the communications network (102) to determine when the wireless communications device (104, 106, 200) is at a nearly out of synchronization state with the communications network (102). In response to determining the wireless communications device (104, 106, 200) is at a nearly out of synchronization state, the wireless communications device (104, 106, 200) sends (310) to the communications network (102), additional control information on a control channel. The wireless communications device (104, 106, 200) receives (312) additional control bits sent by the communications network (102) in response to the communications network (102) receiving the additional control information sent by the wireless communications device (104, 106, 200).
