Title:
DATA TRANSMISSION METHOD, NETWORK EQUIPMENT, AND TERMINAL EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2018/127158
Kind Code:
A1
Abstract:
A data transmission method, network equipment, and terminal equipment. The method comprises: first network equipment determines first information; the first network equipment determines, according to the first information, a demodulation reference signal set comprising one or more demodulation reference signals; and the first network equipment transmits, to terminal equipment, one or more demodulation reference signals in the demodulation reference signal set. In the embodiment, the first network equipment determines the demodulation reference signal set according to the first information, and as a result, the demodulation reference signal set adopted by the first network equipment is different from that adopted by second network equipment, ensuring that the first network equipment and the second network equipment adopt demodulation reference signals orthogonal to each other, preventing an issue of poor demodulation at an terminal when different base stations adopt non-orthogonal demodulation reference signals.
