Phase determining method and apparatus

Abstract

A phase determining method and an apparatus are provided, which are applied to the field of communication technologies, for example, applied to a UWB-based WPAN system, for example, an 802.15.4a protocol, an 802.15.4z protocol, or an 802.15.4ab protocol in 802.15 series protocols, and also applied to a sensing system. The method includes: A transmit end generates a first frame, and then sends the first frame. In this way, a receive end may receive the first frame, and determine phase information based on the first frame. The first frame may include a first CTS, the first CTS includes at least two segment groups, a time interval between adjacent segments in each segment group is a first time interval, and a time interval between adjacent segment groups is a second time interval. Coverage of the first frame is effectively improved.
