Document Type and Number:
WIPO Patent Application WO/2021/036934
Kind Code:
A1
Abstract:
The present application provides a method for sending and receiving an indication. In the method, in order to enable a terminal to know a special sending port that needs to be considered or processed in a targeted manner, a network device sends indication information to the terminal, the indication information being used for indicating one or more special sending ports for a downlink reference signal, the special sending port being a sending port where there is a subcarrier meeting a predetermined condition among subcarriers occupied in downlink reference signal sending ports, and the indication information being further used for indicating one or more subcarriers, corresponding to each first sending port, meeting the predetermined condition. In this way, the terminal can know which sending port is a sending port where there is a subcarrier that meets the predetermined condition among the occupied subcarriers, and which subcarrier among the subcarriers occupied by the sending ports meets the predetermined condition, so that the terminal can perform processing in a targeted manner during the calculation of channel information.
