Although the Btrunc protocol specifies the definition of the second type of group control information, it does not clearly stipulate how the base station periodically sends the second type of group control information
[0004] Since TD-LTE does not have user control information that needs to be delivered periodically, it is impossible to refer to the TD-LTE solution for periodic delivery of group control information. If the fixed period is too long, it will cause the terminal to wait for too long to receive group control information, which will affect user perception

Embodiment Construction
[0022] In order to make the purpose, technical means and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.
[0023] In order to ensure that the base station quickly sends the second type of group control information to the group users, and to ensure that the group monitoring users (UEs that receive group data) that access later can receive the second type of group control information, this application It is proposed that the base station sends the second type of group control information to the group users by using the large and small cycle mechanism.
[0024] figure 1 It is a schematic flow chart of the basic flow of the transmission method of the TCCH channel signal in this application. Such as figure 1 As shown, the method includes:

The present application discloses a method for transmitting a TCCH channel signal, comprising: a base station receiving second-type group control information sent by a core network to a group of users; if the second-type group control information is for the group the first transmission of the user, the base station saves the second type of group control information in the base station cache; if the second type of group control information is not the first transmission for the group user, the base station stores the second type of group control information The control information replaces the second type of group control information of the group users stored in the base station cache; the base station sends the second type of group control information stored in the base station cache N times with the set first period , and then deliver the second type of group control information of the group user stored in the base station cache at a set second cycle. By applying the present application, air interface resources can be saved while ensuring timely reception of group control information.
Description
technical field [0001] The present application relates to communication technology, in particular to a method for transmitting TCCH channel signals. Background technique [0002] Broadband trunking communication (Boardband Trunking Communication, B-TrunC) is a TD-LTE-based "LTE digital transmission + trunking voice communication" private network broadband trunking system standard developed by the Broadband Trunking Communication (B-TrunC) Industry Alliance. It mainly regulates broadband trunking business functions such as trunking voice, trunking video, and media trunking scheduling. It has the characteristics of flexible bandwidth, high spectral efficiency, low delay, and high reliability, and can meet the needs of professional users for voice trunking, broadband data, and emergency command. Scheduling and other needs. [0003] On the basis of the existing TD-LTE logical channels, the Btrunc protocol adds trunking-specific logical channels, such as trunking control channel...
