Method and device for sending control channel

A method for receiving a control channel, comprising:

• sending at least one of first control information or first parameter information to a first communication node;
• determining second transmission parameter configuration information of the control channel according to the at least one of the first control information or the first parameter information;
• and
• receiving, according to the determined second parameter configuration information, the control channel sent by the first communication node,
• wherein the first parameter information comprises at least one of the following information:
• demodulation reference signal information corresponding to the first control information, demodulation reference signal information of a data channel corresponding to the control channel, type information of second control information transmitted on the control channel, channel coding rate information corresponding to the first control information, or time resource information of the data channel or the first control information, and channel state information (CSI) comprised in the first control information, and
• wherein the first control information and the data channel are signals received by the first communication node and the second control information is a signal sent by the first communication node, wherein the second control information is on the control channel.

A device for sending a control channel, comprising:

• a receiving unit, which is configured to receive at least one of first control information and first parameter information;
• a determining unit, which is configured to determine second transmission parameter information about the control channel according to the at least one of the first control information or the first parameter information;
• or
• a sending unit, which is configured to send the control channel to a second communication node according to the second transmission parameter information;
• wherein the first parameter information comprises at least one of the following information:
• demodulation reference signal information corresponding to the first control information, demodulation reference signal information of a data channel corresponding to the control channel, type information of second control information transmitted on the control channel, and channel coding rate information corresponding to the first control information, or
• wherein 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, wherein the second control information is on the control channel.
