1. A method in a network node for enabling scheduling of a User Equipment (UE) configured with Discontinuous reception (DRX) and semipersistent scheduling (SPS), said method comprising:
receiving an Uplink (UL) transmission from the UE in recurring Transmission Time Intervals (TTIs), short TTIs, slots, or sub-slots of the SPS; and
transmitting a HARQ response to the UL transmission and, within a same occasion, transmitting an UL grant or a Downlink (DL) assignment to the UE, provided there is no upcoming preconfigured DRX On-Duration period within a specified time limit, wherein the UL grant or the DL assignment, when transmitted, triggers the UE to stay in DRX active mode for a period.
