CN-122029785-A - Wireless communication method and communication equipment

Abstract

A method of wireless communication and a communication device are provided. The method includes the first device sending first information to the second device, the first information including one or more of second information indicating a proposed first pilot configuration, third information indicating full channel information for a channel, the full channel information for the channel being used to determine the first pilot configuration. In an embodiment of the present application, the first device may send first information for determining the first pilot configuration to the second device, where the first information may include full channel information for indicating the proposed first pilot configuration and/or for indicating the channel. Compared with the traditional scheme of determining pilot frequency configuration based on partial channel information, the method and the device are beneficial to improving the rationality of the selected first pilot frequency configuration, so that the matching degree of the first pilot frequency configuration and the current channel characteristic is improved, and the performance of channel estimation is further improved.
