TRANSMISSION RESOURCE ALLOCATION METHOD, RELATED DEVICE AND COMMUNICATION SYSTEM

摘要

Disclosed in an embodiment of the present invention are a transmission resource allocation method, related device and communication system, the transmission resource allocation method comprising: an access device notifies a user equipment (UE) of a second uplink-downlink configuration modification period, the second uplink-downlink configuration modification period being smaller than a system message modification period; the access device transmits a first message to the UE, the first message carrying an uplink-downlink configuration indication corresponding to the second uplink-downlink configuration modification period, so that the UE can update the uplink-downlink configuration used by the UE according to the uplink-downlink configuration indication. The embodiment of the present invention improves the transmission resource allocation flexibility and frequency spectrum resource utilization rate.
