Abstract

The present invention provides a data receiving method and apparatus. The method includes: receiving a data signal delivered by a base station, where the data signal includes at least two encoded data block groups, and each encoded data block group includes at least one encoded data block; decoding the data signal, and acquiring decoded data blocks obtained by decoding the encoded data blocks; and separately performing CRC detection on each decoded data block, and determining, according to a CRC, obtained through detection, of each decoded data block, whether to execute an SIC operation, and if it is determined to execute an SIC operation, executing CRC detection again on the decoded data block on which an SIC operation is performed, until a repeated CRC result occurs or all CRCs are zero. The data receiving method according to the present invention is used to resolve a problem in the prior art that accuracy of a terminal in receiving downlink data of a four-branch multiple-input multiple-output system is relatively low.

Description

technical field [0001] The invention relates to communication technology, in particular to a data receiving method and device. Background technique [0002] With the continuous development of communication technologies, Multi-input Multi-output (Multi-input Multi-output, hereinafter referred to as MIMO) systems are widely used. For the traditional single-antenna system, the MIMO system can greatly improve the spectrum utilization rate, so that the system can transmit higher-rate data services in a limited wireless frequency band, that is, in the MIMO system, multiple Transmitting antenna and receiving antenna, signals are transmitted and received through multiple antennas at the transmitting end and receiving end, thereby improving the quality of service for each user. [0003] Specifically, in a 4-way (branch) MIMO system, the base station performs bit scrambling, code block segmentation, channel coding, and physical layer hybrid automatic retransmission on the four transp...
