Abstract: A ranging method and apparatus are provided. The method includes processing, by a ranging device, an echo signal of a detection signal based on a time-to-digital conversion ranging manner to determine a first data set. The echo signal is processed based on an analog-to-digital conversion ranging manner to determine a second data set. An output distance set is determined based on at least one parameter in the first data set or the second data set, and one or more of the following relationships: a relationship between at least one of an actual transmit power of the detection signal and a preset power threshold, a relationship between at least one estimated distance and a preset distance threshold, or a relationship between at least one signal parameter of the echo signal and a preset parameter threshold.

Abstract: Embodiments of the present disclosure provide a data channel sending method. In the method, a base station starts a clear channel assessment (CCA) on a data channel for a to-be-sent data channel. If the CCA on the data channel succeeds, the base station sends the data channel in a first subframe within a time window, where the data channel performs rate matching based on a reference signal (RS). The RS includes a first RS or a second RS. The first RS occupies continuous OFDM symbols in a subframe, and the second RS occupies discontinuous OFDM symbols in a subframe. The time window is a preset time window used to send the first RS, and the first RS is used by a user equipment (UE) to perform cell identification and/or a radio resource management (RRM) measurement on a cell served by the base station.
