Title: COMMUNICATION METHOD, BASE STATION AND TERMINAL DEVICE
Abstract:
Provided are a communication method, a base station and a terminal device. The method comprises: a base station sending a signal to a terminal device by means of n sets of ports, wherein each set of ports in the n sets of ports comprises at least two ports, and n is a positive integer greater than or equal to 2; and the base station receiving s sets of first linear combination coefficients sent by the terminal device, wherein each set of first linear combination coefficients is the first linear combination coefficients of one set of ports in the s sets of ports, at least one set of first linear combination coefficients comprises at least two non-zero coefficients, the s sets of first linear combination coefficients are used to determine a first pre-coding matrix, the s sets of ports are included in the n sets of ports, s is a positive integer less than or equal to n, and s is a positive integer greater than or equal to 2. In the embodiments of the present invention, by means of sending s sets of first linear combination coefficients to a base station, the channel feedback accuracy of a terminal device can be improved, thereby being beneficial to improving the transmission performance between the base station and the terminal device.
