Abstract: This application discloses a reference signal transmission method and apparatus. The method includes: generating one or more OFDM symbols, where at least one OFDM symbol includes a PTRS resource block, the PTRS resource block includes at least two of three sequences: a PTRS sequence of Y elements, X elements after the PTRS sequence, and Z elements before the PTRS sequence, and the PTRS resource block occupies a plurality of consecutive resource elements REs, where X, Y, and Z are all integers; and sending the one or more OFDM symbols. According to the foregoing method and apparatus, inter-carrier interference is reduced, thereby improving spectral efficiency.

Abstract: This application provides a communication method, a terminal, and a network device. The communication method includes: repeating, by a first terminal, to-be-transmitted uplink control information for N times to obtain a first data segment, where N is a positive integer; determining, by the first terminal, an orthogonal cover code based on N; multiplying, by the first terminal, the first data segment by the orthogonal cover code to obtain a second data segment; and sending, by the first terminal, the second data segment. By using the communication method, the terminal, and the network device provided in this application, frequency diversity gains of the uplink control information can be increased, transmission flexibility of the uplink control information can be improved, and resource utilization can be increased.
