Title:
MESSAGE FEEDBACK METHOD AND DEVICE FOR CARRIER AGGREGATION
Document Type and Number:
WIPO Patent Application WO/2018/076302
Kind Code:
A1
Abstract:
Provided are a message feedback method and device for carrier aggregation. The method comprises: a terminal receiving a data packet sent by a base station on a first downlink sub-frame of a carrier aggregation combination, wherein the carrier aggregation combination comprises: a first carrier and a second carrier; determining a first time sequence according to a sub-frame configuration of the carrier aggregation combination and a mapping relationship between the sub-frame configuration of the carrier aggregation combination and a time sequence; determining a first uplink sub-frame from sub-frames of the carrier aggregation combination according to the first time sequence; and sending a feedback message to the base station on the first uplink sub-frame. This realizes that a first uplink sub-frame is determined, in the entire carrier combination, to send a feedback message. The range of options is larger, so that the feedback message can be sent by using a closer sub-frame, thereby effectively improving the feedback efficiency.
