A method performed by a network node for deciding whether or not to trigger short Semi Persistent Scheduling (SPS) reactivation of a short SPS activated User Equipment (UE) in a wireless communication network is provided.
The network node receives Uplink, UL, data from the UE over a radio resource. The radio resource comprises any one out of: an SPS resource and a dynamically granted resource. The network node determines a difference of signal quality of the radio resource used for the received UL data compared to a previous signal quality calculated when last of any one out of: deactivation and reactivation of short SPS was triggered. The network node then decides whether or not to trigger short SPS reactivation of the UE based on the determined difference of the signal quality.
