Title: SIGNAL SENDING AND RECEIVING METHOD, APPARATUS AND SYSTEM
Abstract:
Embodiments of the present invention relate to the field of communications. Disclosed are a signal sending and receiving method, an apparatus and a system, which solve a problem that a dynamic signaling overhead for transmitting a noise coefficient. A specific scheme is: a first communication device receiving joint coding information sent by a second communication device, wherein the joint coding information is generated by the second communication device based on a first noise coefficient and a modulation coding policy, and the modulation coding policy is used by the first communication device to decode received data; and the first communication device obtaining the first noise coefficient based on the joint coding information, and parsing the received data based on the first noise coefficient. The present invention is used for sending and receiving signals.
