Abstract

Embodiments of the present invention provide a data sending method, a data receiving method, a sending end device, and a receiving end device. The data sending method provided by the embodiment of the present invention may include: initializing the scrambling code to generate a scrambling code; scrambling the data block according to the scrambling code; repeatedly sending the scrambled data block; and initializing the last scrambling code of the distance data block When the interval is greater than or equal to the preset scrambling code initialization parameter threshold, the scrambling code is initialized to regenerate the scrambling code; the data block is scrambled again according to the regenerated scrambling code; and the re-scrambled data block is repeatedly sent. The embodiment of the present invention can improve the data transmission efficiency between the sending end device and the receiving end device.

Description

technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a data sending method, a data receiving method, a sending end device, and a receiving end device. Background technique [0002] With the development of communication technology, Long Term Evolution (LTE for short) communication technology has become more and more mature, and the network coverage of the LTE system is also becoming denser. [0003] In an LTE system, dense network coverage causes interference between adjacent cells. In order to reduce the interference between adjacent cells, the scrambling code initialization can be used to enable the sending device to perform scrambling initialization once in each subframe. The data sent in each subframe has a different scrambling code. The scrambling code is used to scramble the data block, and the scrambled data block is sent, so that randomization of interference can be realized. In order to ensure th...
