Abstract
Example signal transmission methods and apparatus are described. In one example method, a first initiating device sends a poll frame. The poll frame includes time-frequency location information of N first ultra-wideband (UWB) segment signals, and the poll frame further includes first delay information for each of M second responding devices to reply to the first initiating device with a response frame. The first initiating device receives a plurality of response frames based on a timestamp of the poll frame and the first delay information for each of the M second responding devices to reply to the first initiating device with the response frame.
Claims11
A method for signal transmission, wherein the method is applied to a first initiating device, and the method comprises:
- sending a poll frame, wherein the poll frame comprises time-frequency location information of N first ultra-wideband (UWB) segment signals, and the poll frame further comprises first delay information for each of M second responding devices to reply to the first initiating device with a response frame, and wherein N and M are integers greater than or equal to 2;
- and
- receiving a plurality of response frames based on a timestamp of the poll frame and the first delay information for each of the M second responding devices.
A method for signal transmission, wherein the method is applied to a first responding device, and the method comprises:
- receiving a poll frame, wherein the poll frame comprises time-frequency location information of N first ultra-wideband (UWB) segment signals, and the poll frame further comprises delay information for each of M second responding devices to reply to a first initiating device with a response frame, wherein N and M are integers greater than or equal to 2, and the first responding device is any one of the M second responding devices;
- and
- sending a first response frame to the first initiating device based on a timestamp of the poll frame and the delay information for the first responding device to reply to the first initiating device with the response frame.
An apparatus for communication, wherein the apparatus is used in a first initiating device, and the apparatus comprises:
- one or more processors;
- and
- one or more memories coupled to the one or more processors and storing programming instructions for execution by the one or more processors to:
- send a poll frame, wherein the poll frame comprises time-frequency location information of N first ultra-wideband (UWB) segment signals, and the poll frame further comprises first delay information for each of M second responding devices to reply to the first initiating device with a response frame, and wherein N and M are integers greater than or equal to 2;
- and
- receive a plurality of response frames based on a timestamp of the poll frame and the first delay information for each of the M second responding devices.
