Data scrambling method and related equipment

Abstract

The invention discloses a data scrambling method and related equipment, and the method comprises the steps that network equipment can configure a scrambling recognition associated with downlink control information configuration information or a downlink control parameter; or configuring a plurality of scrambling identifiers associated with different downlink control information configuration information or downlink control parameters; wherein the downlink control information configuration information is parameter information used for obtaining a downlink control channel; wherein the downlink control parameter is a parameter contained in downlink control information or a parameter related to the parameter contained in the downlink control information; the network device may send the one ormore scrambling identifiers to the terminal device. Visibly, the scrambling identifier configured by the embodiment of the invention is associated with the downlink control information configuration information or the downlink control parameter, so that interference randomization can be realized in incoherent transmission.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data scrambling method and related equipment. Background technique [0002] In the fifth generation (5G) communication system, multi-transmission point / multi-panel / multi-beam (Multi-TRP / panel / beam) transmission technology is the key technology to improve the overall performance of the system and solve inter-cell interference problems . The implementation of Multi-TRP / panel / beam transmission technology includes multiple solutions such as joint transmission technology, dynamic transmission point selection technology, non-coherent joint transmission technology, and cooperative scheduling / coordinated beamforming technology.

Problems solved by technology

[0003] Currently, signaling is assigned a scrambling identifier for each user equipment, that is, the same user equipment has only one scrambling identifier. In this way, in Multi-TRP / panel / beam, multiple transmission points / panels / beams When a user equipment sends data, especially in non-coherent transmission, each transmission point adopts its own independent precoding scheme. At this time, the code word is 0. When each transmission point scrambles the transmitted data, because The user equipment identification number and codeword of the equipment are the same, especially a configured scrambling identifier is associated with the user equipment, that is, the same user equipment has only one scrambling identifier, so the scrambling code used by each transmission point for scrambling data The sequence is also the same, which makes it impossible to randomize the data processing of each transmission point through scrambling
