Abstract

The invention provides a transmission method and device, a first communication node, a second communication node and a medium. The method comprises the following steps: sending indication information,wherein the indication information is used for indicating a second communication node to send an uplink signal or indicating the second communication node to receive a downlink signal; and performingsignal transmission with the second communication node according to the indication information.

Description

technical field [0001] The present application relates to a wireless communication network, for example, to a transmission method, a device, a first communication node, a second communication node and a medium. Background technique [0002] With the development of communication technology, the demand for data services continues to increase. The first communication node can determine the second communication node's Channel state information, based on which operations such as frequency domain selective scheduling and closed-loop power control are performed; in addition, the first communication node can also send downlink signals to the second communication node, such as channel state information reference signal (Channel State Information-Reference Signal , CSI-RS), Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH), etc., for the second communication node to receive, process or measure. There are various situations in the above-mentioned signal trans...
