Abstract: The application relates to a method for antenna port indication. A terminal receives information indicating an antenna port set of a pilot from a base station. The antenna port set is used for a resource block (RB) set and the pilot is used for data demodulation. The terminal determines the antenna port set based on the received information. By implementing the solution in the application, transmission resource utilization is improved.

Abstract: Embodiments of the present invention disclose a signal transmission method, including: sending, by a first device, a first reference signal to a second device, where the first reference signal is used for phase tracking; the first reference signal is mapped to a first symbol; the first symbol includes a symbol that carries a data signal and that precedes a second symbol; the second symbol is one or more consecutive symbols carrying a DMRS; and the one or more symbols include the 1st symbol carrying the DMRS. According to the foregoing solution, it can be ensured that a PT-RS is also mapped to a symbol to which a data channel is mapped and that precedes a symbol carrying a DMRS, thereby ensuring phase noise estimation performance.

Abstract: A reference signal transmission method includes: sending, by a terminal, a first reference signal and a second reference signal; and correspondingly, receiving, by a network device, the first reference signal and the second reference signal, where the first reference signal is mapped to a plurality of symbols and is used for estimation of channel state information, the second reference signal is mapped to at least two of the plurality of symbols and is used for phase tracking, and a subcarrier to which the second reference signal is mapped on one of the at least two symbols has a same frequency-domain location as a subcarrier to which the second reference signal is mapped on the rest of the at least two symbols. With the foregoing solution, accuracy of channel state information estimation can be improved.

Abstract: A method and an apparatus for mapping a reference signal are disclosed. The method includes: mapping a target-class signal to a target symbol, where the target symbol is some symbols in a first symbol set on a time-frequency resource block, the first symbol set is a set of some symbols or all symbols on the time-frequency resource block, the target-class signal has at least two functions, and the at least two functions include a function of estimating a parameter that affects signal transmission; and mapping the reference signal to a symbol in the first symbol set other than the target symbol, where the reference signal has the function of estimating a parameter that affects signal transmission. Embodiments of the present invention can save resources.
