In a wireless communication system , a method and apparatus for repositioning a SPS (SEMI-PERSISTENT) operation

摘要

A method and apparatus are disclosed for improving SPS operation in a wireless communication system. The method includes configuring a user equipment (UE) with a downlink (DL) assignment or an uplink (UL) grant through a PDCCH (Physical Downlink Control Channel) addressed by a SPS C-RNTI (Semi-Persistent Scheduling Cell Radio Network Temporary Identity). The method also includes receiving, at the UE, a reconfiguration message for a SPS (Semi-Persistent Scheduling) operation in a higher layer, such as an RRC (Radio Resource Control) layer. The method further includes reconfiguring, at the UE, the SPS operation based on the reconfiguration message if the reconfiguration message includes a release of the SPS operation.
