Abstract: Embodiments of the present application provide a signal sending method, a device, and a system. A base station modulates, by using a first modulation scheme, signaling carried in a control channel, and modulates, by using a second modulation scheme, data carried in a traffic channel; and the base station sends, to UE, a signal obtained after modulation. In this way, the base station can independently select a modulation scheme for the control channel and the traffic channel, avoiding a case in which a modulation scheme used by the control channel and a modulation scheme used by the traffic channel must be the same, so that the base station can flexibly select a channel modulation scheme.

Abstract: The present disclosure describes a message transmission method. In one example method, a first signal is received by a first device from a second device using a radio channel. A second signal, corresponding to and different from the received first signal, is transmitted by the second device to the first device. Information carried by the second signal corresponds to one of M state values. A first sequence corresponding to one or more subcarriers occupied by the second signal is directly proportional to a product of a preset second sequence and a third sequence in a state sequence set. Channel information of the radio channel is estimated by the first device according to the received first signal and the preset second sequence. The information carried by the second signal is determined by the first device according to the estimated channel information of the radio channel and the received first signal.

Abstract: Embodiments of the present invention provide a signal transmission method and device. The method includes: determining, by a sending device, a target precoding matrix V, where V=(H)−1·{tilde over (H)}, H indicates a channel matrix between the sending device and a receiving device, {tilde over (H)} indicates an equivalent channel matrix between the sending device and the receiving device, ({tilde over (H)}H·{tilde over (H)}) or ({tilde over (H)}·{tilde over (H)}H) is a diagonal matrix, and {tilde over (H)} is related to a transmission distance D between the sending device and the receiving device and an element spacing of an antenna of the receiving device; and sending, by the sending device, a signal to the receiving device according to the target precoding matrix V. Because {tilde over (H)} meets a characteristic that ({tilde over (H)}H·{tilde over (H)}) or ({tilde over (H)}·{tilde over (H)}H) is a diagonal matrix, a channel corresponding to {tilde over (H)} can support multiple data stream transmission. Therefore, the signal transmission method and device provided in the embodiments of the present invention can support multiple data stream transmission.

Abstract: An access network device sends first indication information to a terminal device, and sends second indication information to the terminal device. When the second indication information indicates a first value, the first indication information indicates a first port index group in a plurality of port index groups included in a first set. When the second indication information indicates a second value, the first indication information indicates a second port index group in a plurality of port index groups included in a second set. The first port index group and the second port index group have an association relationship.
