Patent ID: 11864193

Abstract:
Disclosed is a method for sending a control channel. The method includes: a first communication node determining second transmission parameter information about the control channel according to at least one of first control information or first parameter information and sending the control channel to a second communication node according to the second transmission parameter information. The first parameter information includes at least one of the following information: information about a demodulation reference signal corresponding to the first control information, information about a demodulation reference signal of a data channel corresponding to the control channel, information about a type of second control information transmitted on the control channel, and information about a channel coding rate corresponding to the first control information. The first control information is sent by the second communication node to the first communication node and the second control information is sent by the first communication node to the first communication node. The second control information is on the control channel. Further disclosed are a device for sending a control channel, a method for receiving a control channel and a device for receiving a control channel.
