Processing method of group data, base station, and terminal

Abstract

The invention discloses a processing method of group data, a base station, and a terminal, for improving the efficiency of a terminal in correctly decoding group data. The processing method of the group data, provided by one embodiment of the invention, comprises the following steps: a base station determining time periods when the group data is respectively issued to a first cell and an adjacent cell of the first cell and redundancy version numbers, wherein the first cell and the adjacent cell of the first cell issue the group data by use of different redundancy version numbers; the base station sending the time periods when the first cell and the adjacent cell of the first cell respectively send the group data and the redundancy version numbers to a terminal; and when current time is the time period when the adjacent cell of the first cell issues the group data, the base station, according to a determined redundancy version, sending the group data to the adjacent cell of the first cell, and the terminal receiving the group data sent by the base station to the adjacent cell.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for processing group data, a base station and a terminal. Background technique [0002] The Long Term Evolution (LTE) technology has been used in trunking communication, and the biggest feature of the LTE network realizing the trunking is the group users of the trunking service and the call mechanism of the trunking. [0003] The cluster call mechanism is that the speaker user takes the dispatcher as the call object, and sends the speech data of the speaker user to the dispatcher through the base station. All the listeners of the speaker are regarded as a whole, and this whole is called a group. The dispatcher forwards the voice data of the speaker to the base station where the group is located. The base station then forwards the voice data to the listening users in the cell. There is at least one group instance in each cell, which has the functions ...

AI Technical Summary

Problems solved by technology

However, after the base station configures the MCS order, regardless of the actual quality of the air interface, it will not be adjusted, and no matter whether the terminal successfully parses the group data sent by the base station, it will not retransmit

[0005] In the actual situation, the channel quality of a small number of monitoring terminals is worse than the channel quality required by the MCS order corresponding to the group. Although these monitoring terminals can receive the group data, they cannot decode it correctly.

Since the base station will not adjust the MCS order, the monitoring terminal will continue to be unable to correctly decode the data, and the group will not retransmit, so it is very difficult for the monitoring terminal to correctly decode the data
