Problems solved by technology

[0004] However, in the LAA system, since the distribution positions of the uplink and downlink subframes are not fixed, it is impossible to predict the actual location of the uplink subframes in the LAA system, so it is even more impossible to determine the HARQ process corresponding to each uplink subframe, which also means that It is difficult to allocate a fixed HARQ process for each uplink subframe

Abstract

Embodiments of the present invention disclose hybrid automatic repeat request process processing methods, equipment and a communication system. The method comprises the steps of determining a target hybrid automatic repeat request (HARQ) process set in multiple HARQ process sets in a process of uplink scheduling for a terminal, wherein the target HARQ process set comprises uplink HARQ processes allocated to uplink subframes scheduled for the terminal, all uplink HARQ processes in the target HARQ process set are not occupied, and the scheduled uplink subframes are corresponding to the uplink HARQ processes in the target HARQ process set; extracting a set number of the target HARQ process set; and sending the set number of the target HARQ process set to the terminal. Through adoption of the embodiments of the present invention, the HARQ processes can be allocated to the uplink subframes of which distribution positions are unfixed.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method, equipment and communication system for processing a hybrid automatic retransmission request process. Background technique [0002] The Licensed Assisted Access (LAA) system can use the unlicensed spectrum (such as the 5GHz spectrum) with the help of the licensed spectrum in the Long Term Evolution (LTE) system. The LAA system uses the Listen Before Talk (LBT) mechanism on the unlicensed spectrum, and the introduction of the LBT mechanism makes the distribution position of the uplink and downlink subframes in the LAA system no longer fixed. [0003] Generally, a hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process is divided into synchronous HARQ and asynchronous HARQ. In the synchronous HARQ process, there is a one-to-one correspondence between the HARQ process and the subframe, while in the asynchronous HARQ process, the HARQ pro...
