Title:
METHOD FOR DETERMINING SCRAMBLING INITIALIZATION SEQUENCE OF DATA AND DATA DESCRAMBLING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/205105
Kind Code:
A1
Abstract:
A method for determining a scrambling initialization sequence of data, comprising: receiving a time-frequency resource library, a multiplexing factor identifier library for non-orthogonal multiple access, and a reference signal port library which are broadcasted by a base station (S11); selecting a time-frequency resource from the time-frequency resource library, selecting a multiplexing factor identifier from the multiplexing factor identifier library and selecting a reference signal port from the reference signal port library (S12); and determining, according to the selected multiplexing factor identifier and/or the selected reference signal port and a first serial number of a cell where a user equipment is located, a scrambling initialization sequence of data that are transmitted by an uplink to the base station on the time-frequency resource (S13). By means of the described method, even if a wireless network temporary identifier is not acquired, the scrambled initialization sequence of the data may still be smoothly determined so as to scramble the uplink data.
