Abstract

The embodiment of the present invention relates to a method for transmitting data, a receiver device and a sender device. The method includes: sending to at least one receiving end device a first TB set mapped with a first data stream and a second data stream, the first data stream and the second data stream being used to transmit the first data signal and the second data signal ; When the TB transmission error in the first TB set, send the second TB set mapped with the third data flow and the fourth data flow to the at least one receiving end device, the third data signal transmitted by the third data flow equal to the inverse of the conjugate of the second data signal, the fourth data signal transmitted by the fourth data stream is equal to the conjugate of the first data signal, the second TB set and the first TB set are used for the at least one A receiving device determines the first data signal and the second data signal. The method for transmitting data, the receiving end device and the sending end device of the embodiments of the present invention can improve the efficiency of data transmission.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for transmitting data, a receiving end device and a sending end device. Background technique [0002] In a Long Term Evolution (Long Term Evolution, LTE) system, a multi-antenna technology may be used to perform space division multiplexing to improve spectrum utilization. For example, antenna 1 and antenna 2 transmit data signals S1 and S2 respectively, and use the same time and frequency resources. The receiving end can recover S1 and S2 through various algorithms, such as Serial Interference Cancellation (SIC). In this example, S1 and S2 may also be sent out by different beams, and the beams are formed by multiple antennas through beamforming. [0003] In LTE, different beams may correspond to different data streams, and different data streams may be mapped to the same or different transmission blocks (Transmission block, TB), and channel coding is in units of TB. ...
