    Abstract: Disclosed are a method and apparatus for determining an RA-RNTI. In the present application, a base station receives a random access preamble sent by a terminal; the base station determines an RA-RNTI according to a time-frequency resource occupied by the random access preamble, and the time-frequency resource is a time-frequency resource of an orthogonal frequency division multiplexing (OFDM) symbol level; and the base station sends a random access response message, and the random access response message includes downlink control information allocated, by the base station, for the terminal, and the downlink control information is scrambled using the RA-RNTI. By means of the present application, an RA-RNTI can be determined during a random access process of an NR system.

    Abstract: Embodiments of the present application relates to a method and device for random access, for use in resolving the problem that no current random access process can satisfy requirements of a satellite communication system. The method of the embodiments of the present application comprises: receiving and obtaining a related parameter in a configuration message, the related parameter comprising common cell delay information; generating a physical random access channel random access preamble (PRACH Preamble) sequence, and determining an uplink sending timing location according to the common cell delay information; and sending the PRACH Preamble sequence on a time-frequency resource corresponding to the uplink sending timing location. A relative transmission delay and a multi-path channel delay from a terminal, to a satellite, and to a base station are compensated according to the determined uplink sending timing location, thereby reducing overheads of a PRACH channel.

    Abstract: Disclosed are a non-orthogonal multiple access (NOMA) multi-layer transmission method and an apparatus therefor. In the present disclosure, a terminal determines a spread spectrum sequence group for NOMA multi-layer transmission, with the terminal being configured for NOMA multi-layer transmission, wherein the spread spectrum sequence group includes N spread spectrum sequences, the N spread spectrum sequences correspond to N data layers, the N spread spectrum sequences are mutually orthogonal, N is the number of data layers of NOMA multi-layer transmission, and N is an integer greater than 1; and the terminal sends data, the data comprising the N data layers using the spread spectrum sequence group for spectrum spreading. After the terminal uses the spread spectrum sequences in the spread spectrum sequence group to carry out spectrum spreading on the N data layers, it can be ensured that the data layers, after undergoing spectrum spreading, are mutually orthogonal, such that the data transmission performance of the terminal can be improved.
