Title:
METHOD AND DEVICE FOR FEEDING BACK DOWNLINK HARQ OF TDD SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/103289
Kind Code:
A1
Abstract:
Provided are a method for feeding back a downlink HARQ of a TDD system and a device for feeding back a downlink HARQ of a TDD system. The method for feeding back a downlink HARQ of a TDD system comprises: receiving downlink data transmitted over the sub-frame n of the current frame; feeding back, over a target uplink sub-frame, HARQ ACK or NACK feedback information for the downlink data, the target uplink sub-frame being the uplink sub-frame n+k of the current frame or being the uplink sub-frame (n+k)%10 of the next frame adjacent to the current frame, % being a modulus operator, n being an integer of 0~9, k being a preset value greater than 0. The technical solution of the present invention allows the downlink HARQ feedback time sequence to satisfy the lowest latency requirement of the TDD system, and meanwhile can effectively balance control information overheads over respective uplink sub-frames.
