Abstract: A method, a device and a system for signal transmission are disclosed in embodiments of the present invention. The method comprises: selecting a multiplexing mode of signals to be transmitted by a cell according to interference strength received by the cell and/or interference strength received by a neighboring cell; notifying a receiver of the multiplexing mode of the signals to be transmitted by the cell; and transmitting the signals to be transmitted by the cell according to the multiplexing mode of the signals to be transmitted by the cell. Through the signal transmission method, device and system provided herein, the multiplexing mode is selected adaptively according to the interference strength. Therefore, the inter-cell interference is reduced, the reliability of channel detection is improved, the system complexity is reduced, and the cost is saved.

Abstract: The unicast communication method includes: grouping, by a base station, terminals based on channel condition levels according to measurement information of an uplink channel, so as to obtain at least two channel condition level groups; selecting a modulation-coding mode suitable for each channel condition level group, and decoding a packet to be sent to a terminal by using fountain codes, so as to obtain a fountain code block; sending the fountain code block to the terminal; receiving, by the terminal, the fountain code block of the packet sent by the base station; determining a channel condition level group to which the terminal belongs, decoding the fountain code block by using the modulation-coding mode corresponding to the channel condition level group; and sending or not sending acknowledgment feedback to the base station.
