Abstract

The invention provides a private network channel scrambling method and a private network channel scrambling device. According to the invention, a wireless communication system in a private network is composed of a plurality of discrete frequency points, and each discrete frequency point bears a respective channel. The method comprises the step of carrying out scrambling on channel data by adopting a scrambling code sequence carrying an absolute frequency point index number. The method and the device provided by the invention solve a problem of peak-to-average power ratio caused by an existing channel scrambling method in the condition that the wireless communication system in the private network is composed of a plurality of discrete frequency points.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a private network channel scrambling method and device. Background technique [0002] In a Long Term Evolution (LTE for short) system, a scrambling code is designed for each physical channel, and the characteristics of the scrambling code are used to reduce mutual interference of signals between cells. Taking the Physical Downlink Control Channel (PDCCH for short) as an example, in each subframe, the downlink control information (Downlink Control Information, DCI for short) is in accordance with Table 5.1.3- 1 for channel convolutional coding. Blocks of bits transmitted on multiple PDCCH channels in a subframe will be multiplexed together to form bit blocks b ( 0 ) ( 0 ) , . . . , ...
