METHODS FOR DETERMINING SIGNALING TIMING AND SCHEDULING TIMING IN DETERMINING UPLINK AND DOWNLINK RECONFIGURATION, AND USER EQUIPMENT

摘要

The present invention provides a method for determining HARQ-ACK feedback timing and uplink scheduling timing, and for managing the synchronous uplink HARQ process during uplink and downlink reconfiguration. The method comprises: when uplink and downlink reconfiguration is performed, determining whether at least one HARQ-ACK feedback associated with the last frame of a previous uplink and downlink configuration cannot be transmitted in the first frame of a current uplink and downlink configuration; and when the HARQ-ACK feedback cannot be transmitted in the first frame of the current uplink and downlink configuration, the HARQ-ACK feedback follows a new timing determined by the previous and the current uplink and downlink configuration.
