Information sending method, information receiving method, apparatus, device, and medium for channel state information feedback

A first device, comprising:

• a processor, a transceiver connected to the processor, and a memory configured to store executable instructions for the processor;
• wherein the processor is configured to load and execute the executable instructions to perform a method for sending information, comprising:
• receiving an indication message sent by a second device in a mobile communication system, wherein the indication message is used for indicating a mode in which the first device feeds back a supplementary feedback information;
• and
• sending the supplementary feedback information to the second device in the mobile communication system according to the indication message;
• wherein the supplementary feedback information is used for incrementally updating complete channel information, or the supplementary feedback information is used for predicting the complete channel information;
• wherein the complete channel information is used for describing a channel quality condition about a channel;
• wherein the indication message comprises a second message, the second message comprising first configuration information used for configuring the first device to periodically feed back the supplementary feedback information;
• wherein sending the supplementary feedback information to the second device in the mobile communication system according to the indication message comprises:
• periodically sending the supplementary feedback information to the second device in the mobile communication system according to the first configuration information indicated by the second message;
• and
• wherein the method further comprises:
• receiving a third message sent by the second device, wherein the third message is used for configuring the first device to stop periodical feedback of the supplementary feedback information;
• stopping periodical sending of the supplementary feedback information to the second device in the mobile communication system in response to receipt of the third message;
• sending the complete channel information to a second node in the mobile communication system;
• and
• receiving a first configuration message sent by the second node, wherein the first configuration message comprises second configuration information used for configuring the first node to periodically feed back the complete channel information:
• wherein sending the complete channel information to the second node in the mobile communication system comprises:
• periodically sending the complete channel information to the second node in the mobile communication system according to the second configuration information indicated by the first configuration message:
• wherein the supplementary feedback information is fed back to the second node by the first node according to a first period, and the complete channel information is fed back to the second node by the first node according to a second period, the first period being shorter than the second period.

A second device, comprising:

• a processor, a transceiver connected to the processor, and a memory configured to store executable instructions for the processor;
• wherein the processor is configured to load and execute the executable instructions to perform a method for receiving information, comprising:
• sending an indication message to a first device in a mobile communication system, wherein the indication message is used for indicating a mode in which the first device feeds back a supplementary feedback information;
• and
• receiving the supplementary feedback information sent by the first device in the mobile communication system according to the indication message,
• wherein the supplementary feedback information is used for incrementally updating complete channel information, or the supplementary feedback information is used for predicting the complete channel information;
• wherein the complete channel information is used for describing a channel quality condition about a channel;
• wherein sending the indication message to the first device comprises:
• sending a second message to the first device, wherein the second message comprises first configuration information used for configuring the first device to periodically feed back the supplementary feedback information;
• wherein the supplementary feedback information is periodically sent by the first device in the mobile communication system according to the first configuration information indicated by the second message;
• wherein the method further comprises:
• sending a third message to the first device, wherein the third message is used for configuring the first device to stop periodical feedback of the supplementary feedback information;
• receiving the complete channel information from the first node in the mobile communication system;
• and
• sending a first configuration message to the first node, wherein the first configuration message comprises second configuration information used for configuring the first node to periodically feed back the complete channel information,
• wherein receiving the complete channel information from the first node in the mobile communication system comprises:
• periodically receiving the complete channel information from the first node in the mobile communication system according to the second configuration information indicated by the first configuration message:
• wherein the supplementary feedback information is fed back to a second node by the first node according to a first period, and the complete channel information is fed back to the second node by the first node according to a second period, the first period being shorter than the second period;
• and
• wherein periodical sending of the supplementary feedback information by the first device in the mobile communication system is stopped in response to receipt of the third message.
