Patent ID: 10334619

Abstract:
Embodiments herein relate to a method performed by a wireless device (10) for handling uplink, UL, communication from the wireless device (10) in a wireless communication network (1), which wireless device is configured with one or more Semi Persistent Scheduling, SPS, grants and to skip padding transmissions of SPS grant. The wireless device receives a dynamic UL grant from a radio network node indicating one or more resources for an UL transmission to the radio network node. The wireless device determines that a Hybrid Automatic Repeat Request, HARQ, buffer for transmission of a previous transmission comprises data or not, which HARQ buffer is associated with a same HARQ process as the dynamic UL grant. Furthermore, the wireless device (10) transmits the data in the HARQ buffer using one or more resources as indicated by the dynamic UL grant or as indicated by the SPS grant when determined that the HARQ buffer comprises data, and transmits new UL data using the one or more resources as indicated by the dynamic UL grant when determined that the HARQ buffer comprises no data.
