METHOD AND APPARATUS FOR SEMI-PERSISTENT RESOURCE RELEASE BY WIRELESS COMMUNICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a reliable method for causing a user agent to release semi-persistent scheduling resources.SOLUTION: Provided is a method for causing a user agent (UA) to release at least one of uplink and downlink semi-persistent communication resources in a mobile communication system. The method comprises the steps of: using a semi-persistent scheduling radio temporary network identifier (SPS-RNTI) assigned to the device to decode a control message on a physical downlink control channel (PDCCH) which includes downlink control information (DCI) in a plurality of DCI fields arranged in a DCI format; and, if data from the at least one of the DCI fields is identical to a fixed SPS release value, releasing at least one of the uplink and downlink semi-persistent communication resources.
