Title:
METHOD FOR INDICATING UPLINK CHANNEL STATE, COORDINATOR AND USER EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/072197
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present invention are a method for indicating uplink channel state, a coordinator and a user equipment, capable of avoiding a transmission conflict of an uplink channel and improving throughput of a system. The method in the embodiments of the present invention comprises: a coordinator determining an uplink channel state; the coordinator generating a downlink signal according to the uplink channel state; and the coordinator sending the downlink signal to a user equipment (UE), the downlink signal being a downlink signal frame or an idle pattern frame, and frame headers of both the downlink signal frame and the idle pattern frame comprising uplink channel state indication fields, the uplink channel state indication fields being used to indicate the uplink channel state; or, the downlink signal being an idle pattern sequence, and the idle pattern sequence indicating the uplink channel state.
