During discontinue reception (DRX) operation of a mobile terminal of a wireless communications network, methods to ensure that user equipment is in an awake mode when a network node sends a scheduling grant on the physical downlink control channel (PDCCH). Dynamic scheduling (DS) and semi-persistent scheduling (SPS) grants may appear on PDCCH only once. One method defines every received downlink (DL) semi-persistent scheduling (SPS) signal in a subframe as active time in a configured DRX cycle and includes in said defining active time any occurrence of a DL assignment being configured for the subframe. A second method receives an indication of a downlink transmission or a configured downlink assignment configured for the current PDCCH subframe, starts a Hybrid Automatic Repeat request (HARQ) Round Trip Timer (RTT) whether UE is in active time or not, and stops a drx-RetransmissionTimer for the corresponding HARQ process whether UE is in active time or not. |
