METHOD AND DEVICE FOR IMPLEMENTING HYBRID AUTOMATIC RETRANSMISSION REQUEST (HARQ) BASED ON TIME DIVISION DUPLEX (TDD) SYSTEM

摘要

The present invention discloses a method and device for implementing Hybrid Automatic Retransmission Request (HARQ) based on Time Division Duplex (TDD) system, wherein the method includes: the base station determines the retransmission interval of HARQ process based on the predetermined information and service requirement, wherein the retransmission interval is integral multiple of a wireless frame's time length, and the predetermined information includes the ratio of upstream subframe number to downstream subframe in a wireless frame, the distribution of the control channels, and the processing delay of upstream/downstream. By virtue of the technical solution of the present invention, according to different HARQ processes, the retransmission interval of HARQ process is set to be integral multiple of a wireless frame's time length, and the retransmission interval is updated based on the resource configuration, the retransmission delay is processed flexibly, so the flexibility of HARQ process is increased.
