Abstract: This application provides a reference signal configuration method and apparatus. The method includes: determining configuration information of a reference signal based on a first parameter, where the first parameter includes at least one of a transmission feature, a subcarrier spacing, an operating band of the subcarrier spacing, system bandwidth, a quantity of aggregated time-domain resource units, and a quantity of symbols that are in aggregated time-domain resources and to which the reference signal is mapped; and generating the reference signal based on the configuration information. According to the reference signal configuration method and apparatus in this application, a new reference signal design can be proposed for a communications system, so as to meet a configuration requirement of the communications system.

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.
