Abstract

The invention discloses a data sending and receiving method, device, transmitter and receiver of a double transmission block, wherein the method includes: dividing the data to be sent into two parts, wherein each part is divided into two parts according to the corresponding predetermined coding modulation mode Generate transmission blocks TB1 and TB2; modulate the transmission block TB1 into a complex symbol sequence S1 with a certain power, and modulate the transmission block TB2 into a complex symbol sequence S2 with a certain power; superimpose S1 and S2 to generate a new transmission block corresponding to The complex symbol sequence S3 corresponding to the new transport block has the Gray attribute; the new transport block is sent to the receiver. The invention improves the frequency spectrum efficiency, makes the superimposed symbol constellation point have the Gray attribute, improves the SIC demodulation performance, and can allocate different power for different data streams.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data sending and receiving method, device, transmitter and receiver of a double transmission block. Background technique [0002] In the communication between the base station and the UE, according to the channel conditions between the base station and the UE, one transmission block that can match the channel and have a certain Modulation Coding Scheme (MCS for short), that is, a certain spectral efficiency, can be transmitted at a time. Therefore, a cellular communication standard will clearly specify a set of coding and modulation methods to match different wireless channels. In actual communication, the actual channel quality may be very good. For example, if the UE is in the center of the cell, the channel quality at this time is higher than that required by the highest MCS in the standard. Under the existing MCS standard, when the SNR condition of the UE in the cell is ...
