Problems solved by technology

In Rel-15, in the PDSCH randomization method, the initial value of the scrambling sequence (scrambling sequence) depends on the parameter - dataScramblingIdentityPDSCH, but this parameter has only one value for a bandwidth part (BWP, BandWidth Part), so if in a certain When multiple PDSCHs are transmitted from different beams (Beam) or transmitting and receiving nodes (TRP, Transmit Receive Point) on a BWP at the same time, the scrambling method and parameters used are the same, so that the mutual interference cannot be randomized

Abstract

Provided in an embodiment of the present application are a data scrambling method and device, and a communication device. The method comprises the steps: a first device determines scrambling information corresponding to a plurality of physical channels, wherein different physical channels are corresponding to different scrambling information; the first device descrambles the received physical channel and/or scrambles the physical channel to be sent based on the scrambling information.

Description

[0001] This application is the PCT international patent application PCT / CN2018 / 113538 with the filing date of November 1, 2018, which entered the Chinese national phase with the Chinese patent application number 201880097743.1, and the title of the invention is "a data scrambling method and device, and communication equipment" Divisional application. technical field [0002] The embodiments of the present application relate to the technical field of mobile communication, and in particular to a data scrambling method and device, and communication equipment. Background technique [0003] There will be interference between different Physical Downlink Shared Channels (PDSCH, Physical Downlink Shared Channel), and mutual interference between PDSCHs needs to be randomized. In Rel-15, in the PDSCH randomization method, the initial value of the scrambling sequence (scrambling sequence) depends on the parameter - dataScramblingIdentityPDSCH, but this parameter has only one value for ...
