Abstract: An information mapping method includes mapping, by a transmitting end device, first information to second information on a delay-Doppler frame. The delay-Doppler frame includes M×N grids, M is the total number of delay indexes, N is the total number of Doppler indexes. The delay-Doppler frame includes at least two subframes, and each subframe includes a first guard interval portion, a first mapping portion, and two second mapping portions. The two second mapping portions occupy grids corresponding to kmax Doppler indexes at a head and a tail of the subframe in a Doppler direction, and the first mapping portion occupies grids corresponding to (N/G−2kmax) Doppler indexes of the subframe; G being the number of subframes in the delay-Doppler frame. Information mapped to second mapping portions at heads of different subframes is the same, and information mapped to second mapping portions at tails of different subframes is the same.

Abstract: A transmission method includes determining, by a communication device, a target transmission solution of a target signal. The target transmission solution is a first transmission solution or a second transmission solution, the first transmission solution is a transmission solution based on an OFDM communication system, and the second transmission solution is a transmission solution based on an OTFS communication system.

Abstract: A signal transmission method includes converting, by a first communication device, a first signal into a time-frequency domain to obtain a second signal; and performing, by the first communication device, windowing on the second signal in the time-frequency domain. The first communication device includes a transmit end of the first signal and/or a receive end of the first signal. In a case that the first communication device is the transmit end, the first signal is a signal in a delay-Doppler domain, and the second signal obtained through windowing is used for being converted from the time-frequency domain to a time domain. In a case that the first communication device is the receive end, the first signal is a signal in the time domain, and the second signal obtained through windowing is used for being converted from the time-frequency domain to the delay-Doppler domain.

Abstract: A reference signal sequence generation method includes obtaining, by a first device, a target neural network; and obtaining, by the first device, a target reference signal sequence based on the target neural network. The target neural network includes N target neuron groups, and each target neuron group corresponds to one target weight parameter; and the target reference signal sequence includes N target elements in one-to-one correspondence to N target weight parameters. N is a positive integer.

Abstract: A training data set obtaining method includes determining, based on degrees of contribution of transmission conditions to an optimization objective of a neural network, data volumes of training data under the transmission conditions; and obtaining, based on the data volumes of the training data under the transmission conditions, the training data under the transmission conditions, to form a training data set for training the neural network. The degrees of contribution of the transmission conditions to the optimization objective of the neural network represent degrees of impact of the transmission conditions on a value of the optimization objective of the neural network.
