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

Claim 0:
1. A data transmission method in backscatter communication, the method comprising:
generating a first frame, wherein the first frame carries first data and second data, the first data and the second data in the first frame use different modulation schemes; and
sending the first frame to a first tag and a second tag, wherein the first data is obtained by the first tag and the second data is obtained by the second tag,
wherein:
the first data uses amplitude modulation, and the second data uses phase modulation; or
the first data uses phase modulation, and the second data uses amplitude modulation; or
both the first data and the second data use amplitude modulation, and the first data and the second data have different amplitude values.
