Allocation management method of downlink harq process

Abstract

This application discloses a downlink HARQ process allocation management method, which binds the physical subband number with the HARQ context information, and queries and sends the subband number, user identifier and wireless frame number of the physical subband according to the scheduling information. The HARQ context corresponding to the physical subband obtains the process ID and process status of the HARQ process allocated to the UE. By adopting the present invention, the efficiency of the HARQ process allocated to the UE can be obtained quickly, the scheduling efficiency is improved, and the HARQ context resource overhead of the system is reduced.

Description

technical field [0001] The present invention relates to the field of private network wireless communication, in particular to a downlink hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) process allocation management method. Background technique [0002] At present, the 230MHz frequency band is mainly used in data transmission stations to undertake remote data collection work. Because the provided rate is very low, it can only be used for some simple communication applications, and cannot meet the growing business needs of smart grids and sensor networks. According to the future planning of the State Grid, it is required to find a new broadband communication technology to meet the business needs of its distribution network automation, load management, electricity consumption information collection, smart grid user services, emergency repairs, and video surveillance in special areas. [0003] The 230MHz frequency band private network wireless communicati...

Problems solved by technology

Since the 230MHz private network wireless communication system uses a one-to-one binding relationship between HARQ processes and users, that is, one HARQ context is bound to one user, so it is necessary to traverse all online users to find the HARQ processes that can be allocated every time a user is scheduled. , so that when there are many online users, the traversal time will be longer, resulting in a longer scheduling time, which in turn reduces system performance

It can be seen that the HARQ processing mechanism of the existing system is difficult to meet the needs of a single cell to support a large number of users on the basis of the same processor capability and no increase in hardware costs.
