Abstract

The invention relates to the technical field of communication, in particular to a method, equipment and a system of indicating and confirming a transmission format combination. The method, the equipment and the system of indicating and confirming the transmission format combination are used for solving the problems that in the prior art, system overhead is increased and network transmission efficiency is reduced by adopting an explicit type indicating transmission format combination. The method of indicating the transmission format combination comprises the steps that a sending side confirms a planisphere mapping mode combination corresponding to a transmission format combination of a receiving side needing indications according to a corresponding relation of the transmission format combination and the planisphere mapping mode combination, and confirms modulation symbols corresponding to each set of transmission data, and sends the confirmed modulation symbols to the receiving side according to corresponding planisphere mapping modes corresponding to each set of transmission data of the confirmed planisphere mapping mode combination. By using the corresponding relation of the transmission format combination and the planisphere mapping mode combination, and an implicit type indicating transmission format combination, the method, the equipment and the system of indicating and confirming the transmission format combination avoid the system overhead needed by the explicit type indicating transmission format combination, and improve network transmission efficiency.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for indicating and determining a transmission format combination. Background technique [0002] In the traditional data transmission process, the sender needs to send the Transport Format Combination Indicator (TFCI, Transport Format Combination Indicator) corresponding to the data to be transmitted to the receiver through a certain bit overhead, that is, the traditional transmission format adopts an explicit indication method , where TFCI represents the current transport format combination indication, a TFCI value corresponds to a transport format combination, and TFCI is used to inform the receiver of the currently valid transport format combination, that is, how to decode, demultiplex, and when appropriate After receiving the TFCI, the receiver determines the transmission format combination corresponding to the data currently sent by ...
