<p>The present application relates generally to uplink and downlink resources of a radio Access Network (RAN), Radio Resource Control (RRC), and Voice over IP (VoIP). One 3GPP solution to avoid control channel limitation for the VoIP capacity is Semi-Persistent Scheduling (SPS). When using this SPS function the RAN does not need to send a downlink assignment or an uplink grant to a user equipment (UE), which saves the control channel capacity. Discontinuous Reception and Transmission (DRX/DTX) can be utilised as a function that reduces power consumption at the UE. The present invention synchronises the SPS function and the DRX / DTX function. The method of transmission or reception in accordance with the invention is based on a duty cycle which contains on period and an off period. When the RAN performs the method, it signals at least a part of a configuration and a resource allocation to a UE. The configuration discloses: a) length of the duty cycle, b) a starting time of the duty cycle, and c) a length of the on period. The transmission or reception is to happen according to the resource allocation, at the UE, within at least one on period of the duly cycle. When most of the transmission or reception happens within the on periods, the off periods are long and contiguous, thus saving the battery of the UE. The configuration discloses information that delays starting of a duty cycle at least until a trigger.</p> |
