Abstract

The invention provides a signaling transmission method, device and system. the method comprises the following steps: a first transmission node obtains rules for mapping code words to a transmission layer, and the first transmission node sends first signaling to a second transmission node; the first signaling is used for carrying at least one of the followings: the rules for mapping the code words to the transmission layer, first indication information and second indication information; the first indication information is used for indicating the second transmission node to adopt a predetermined information channel state information CSI calculation method to determine information channel state information CSI of an information channel between the first transmission node and the second transmission node; the second indication information is used for indicating the second transmission node to feed feedback content included in the information channel state information CSI back to the first transmission node, a problem that non-relevant JT technologies are low in information transmission efficiency based on relevant technologies can be solved, and information transmission efficiency of the non-relevant JT technologies can be improved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a signaling transmission method, device and system. Background technique [0002] In a Long Term Evolution (LTE for short) system, due to the adoption of Orthogonal Frequency Division Multiplexing (OFDM for short) technology, interference within a cell is generally small, but due to frequency multiplexing between cells, As a result, the interference between cells is relatively large, which becomes the main interference problem in the LTE system, resulting in poor cell edge performance. In order to improve the performance of cell-edge users and meet the requirements of cell-edge spectrum efficiency, the Long Term Evolution-Advanced (LTE-A) system introduces Coordinated Multi-Point (CoMP) transmission. CoMP technology provides services for a cell edge user at the same time through the coordination of multiple adjacent base stations or nodes, so as to reduce the co-frequency inte...
