Abstract: Methods, systems, and devices for multiple access with interference mitigation are described. An exemplary implementation of interference mitigation in a multiple access scheme includes rearranging a N-th bit stream corresponding to a N-th portion of the input bit stream to generate a N-th rearranged bit stream of K rearranged bit streams, for N=1, 2, . . . , K, generating a modulated symbol stream of hierarchical QAM symbols based on the K rearranged bit streams, where bits from the first rearranged bit stream correspond to one or more most significant bits of the hierarchical QAM symbols, bits from the K-th rearranged bit stream correspond to one or more least significant bits of the hierarchical QAM symbols, and bits from a second to (K−1)-th rearranged bit stream correspond to one or more remaining bits of the hierarchical QAM symbols, and transmitting a signal generated from the modulated symbol stream.

Abstract: Methods, systems, and devices for multiple access with interference mitigation are described. A wireless communication method is provided to comprise: generating, from information bits, a modulated signal; spreading the modulated signal using a spreading code to provide a spread data signal; processing the spread data signal through a randomization; and transmitting an orthogonal frequency division multiplexing (OFDM) signal based on an output of the processing.

Abstract: A data transmission method is provided. The method includes: a transmitter generates a transmission signal on the basis of transmission information and modulates, by means of a carrier modulation, the transmission signal to a target time-frequency resource for transmission. The transmission information at least includes terminal identification information; or at least includes terminal identification information and signaling information; or at least includes terminal identification information and data information; or at least includes terminal identification information, data information and signaling information; or at least includes terminal identification information and cell identification information; or at least includes terminal identification information, cell identification information and signaling information; or at least includes terminal identification information, cell identification information and data information; or at least includes terminal identification information, cell identification information, data information and signaling information. A transmitter, a receiver and a storage medium are further provided.

Abstract: Provided are a message sending method and device, and an electronic device. The method includes: sending, by a first node, a message to a second node, wherein the message includes at least one of: a first reference signal carried on a first resource, or a data packet carried on a second resource; wherein the first reference signal belongs to a first reference signal set, and the first resource belongs to a first resource set; the second resource belongs to a second resource set; and the first resource set and the second resource set have a gap in a time domain, and the value of the gap is greater than or equal to 0.
