Problems solved by technology

Therefore, when the base station uses a smaller MCS order to allocate bandwidth for the call service to be performed by each group, it needs to allocate more RBs, resulting in a waste of transmission resources.

Embodiment Construction

[0043] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention.

[0044] First, an application scenario of the embodiment of the present invention is introduced.

[0045] See figure 1 , figure 1 Shown is an architecture diagram of a communication system. figure 1 It includes a base station 101 and multiple terminals 102. The base station 101 may be an evolved base station (Evolved Node B, eNB or e-NodeB), and the terminal 102 is a terminal used by a user, such as a walkie-talkie. People can divide the multiple terminals 102 into multiple groups according to the services performed between the multiple terminals 102 in advance, and each group can include multiple terminals 102. After multiple terminals 102 are divided into multiple groups, t...

Abstract

The invention discloses a method for adjusting a modulation and coding mode and a base station, which achieve the beneficial effect of saving transmission resources. The adjustment method of the modulation and coding method includes: the base station allocates bandwidth for at least one group call service according to the order of the preset modulation and coding method MCS adopted; wherein, the terminals under the coverage of the base station are divided into multiple groups, and each group includes multiple groups. terminals, the group call service is a service in which any terminal and other terminals in any one group call at the same time; if the bandwidth allocated for the at least one group call service is greater than the first preset bandwidth, the base station increases the bandwidth The order of the MCS adopted for the at least one group call service.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a modulation and coding method adjustment method and a base station. Background technique [0002] In some industries, at the same time, a user needs to know the work of other users so as to schedule the work of other users. For example, in the property management and security industry, supervisors need to know the working conditions of the staff they lead, so as to schedule the work of these staff. To this end, the current system can provide group call services. The group call service is a service that occurs in a group composed of multiple terminals. In the group call service, there can only be one terminal that actively initiates the call, and the remaining terminals are called parties. For example, a group call service can be a conversation that occurs in a group consisting of multiple terminals. During the conversation, a terminal can actively initiate a call to ...
