DATA TRANSMISSION METHOD, DATA TRANSMISSION APPARATUS, BASE STATION, AND USER EQUIPMENT

WIPO Patent Application WO/2017/049582

A1

Disclosed is a data transmission method applied to a base station and a user equipment. The method comprises: a base station determines configuration information of a PUCCH and configuration information of an SRS, and sends the configuration information of the PUCCH and the configuration information of the SRS to a UE in a cell; the UE determines a frequency domain resource for transmitting the PUCCH according to the configuration information of the PUCCH, and determines a frequency domain resource for transmitting the SRS according to the configuration information of the received SRS; and the base station receives, according to the configuration information of the PUCCH, a subcarrier that is sent by the UE and that carries the PUCCH, and performs demodulation to obtain the PUCCH, and the base station receives, according to the configuration information of the SRS, a subcarrier that is sent by the UE and that carries the SRS, and performs demodulation to obtain the SRS. Based on the data transmission method disclosed in the present invention, a PUCCH and an SRS are multiplexed on a single symbol structure, and the PUCCH and the SRS are transmitted between a UE and a base station, and the utilization rate of frequency domain resources is improved. Also disclosed are a base and a user equipment.
