Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A communication system, comprising:
a base station and a terminal device;
wherein the base station is configured to:
scramble data based on a first sequence, wherein the first sequence is a portion of a second sequence and the first sequence starts from a location in the second sequence, wherein the first sequence and the second sequence satisfy: c(n)=c1(n+x), c(n) represents the first sequence, c1(n1) represents the second sequence, x represents the location in the second sequence and is determined based on an index of a beam, n and n1 are integers, 0≤n≤M−1, 0≤n1≤L−1, L>M, M is a length of the first sequence, and L is a length of the second sequence; and

send the scrambled data to the terminal device; and
wherein the terminal device is configured to:
receive the scrambled data from the base station; and
descramble the scrambled data based on the first sequence.
