203, data message and transmitting terminal are verified and send to receiving terminal.

Data message and transmitting terminal are verified and send to reception together with air interface by transmitting terminal physical layer End physical layer.

204, the data reception acknowledgement that this receiving terminal returns is received.

This data reception acknowledgement returns to when in transmitting terminal verification by receiving terminal and being verified with receiving terminal and be identical Transmitting terminal.

Receiving terminal physical layer receive data message and transmitting terminal verification and after, first data message is entered Row verification calculate, draw receiving terminal verification and, then, by transmitting terminal verification and with receiving terminal verification and enter Row compares, and data message and transmitting terminal is verified and send extremely with receiving terminal verification result of the comparison information Receiving terminal wireless chain control layer.Receiving terminal wireless chain control layer receive transmitting terminal verification and with reception End verification, with after identical information, sends data reception acknowledgement to transmitting terminal wireless chain control layer.Data Receive confirmation and pass sequentially through receiving terminal physical layer and transmitting terminal physical layer, finally arrive transmitting terminal wireless link Key-course.

205, structure transmitting terminal transmission control layer confirmation message.

After the wireless chain control layer of transmitting terminal receives data reception acknowledgement, structure transmitting terminal transmission controls Layer confirmation message.

In transmission control protocol, transmitting terminal transmission control layer needs to receive receiving terminal transmission control layer and sends Transmission control layer confirmation message after, just send new data.Owing to, in abovementioned steps 105, will connect The transmission control layer confirmation message that the transmission control layer of receiving end sends abandons, and transmitting terminal will not receive receiving terminal The transmission control layer confirmation message that sends of transmission control layer.It is the transmission control making transmitting terminal in the case Preparative layer sends new data, i.e. need to be sent by transmitting terminal oneself one transmission control layer confirmation message of structure End transmission control layer confirmation message.The format and content of this transmitting terminal transmission control layer confirmation message and reception The format and content of the transmission control layer confirmation message that the transmission control layer of end sends is consistent.

206, transmitting terminal transmission control layer confirmation message is passed to the transmission control layer of transmitting terminal.
