Abstract: This application relates to a method for determining a length of an low-density parity-check (LDPC) code word in a ultra-wideband (UWB) system and a related apparatus. The method includes a communication apparatus that determines a length of an LDPC code based on a length of a to-be-encoded information bit. When the length of the information bit ranges from 0 to 324, a 648-bit LDPC code is selected. When the length of the information bit ranges from 325 to 648 or from 973 to 1296, a 1296-bit LDPC code is selected. When the length of the information bit ranges from 649 to 972, a 1944-bit LDPC code is selected. According to embodiments of this application, higher performance gain can be achieved.

Abstract: This application relates to an information exchange method and a related apparatus. The method includes: A resource-limited node (for example, a STA) requests to enable an AI-assisted rate adaptation function, and after agreeing to the request, a node with a more powerful function (for example, an AP) sends, to the STA, related information of a neural network (such as a structure, a parameter, an input, and an output of the neural network) that has been trained, so that the STA determines the neural network based on the related information, and performs inference and decision-making based on data observed by the STA, to obtain a rate adaptation decision result. According to embodiments of this application, a basis can be provided for the resource-limited node to implement AI-assisted rate adaptation, and further, performance can be improved.

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.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: sending, on a first narrowband channel, a first frame used to trigger data measurement; sending a first UWB signal and receiving a second UWB signal on a first ultra-wideband UWB channel, where the first UWB signal and the second UWB signal are used to perform the data measurement to obtain a data measurement result; and specifically, sending, on a second narrowband channel, a first trigger frame used to trigger reporting of a first measurement result. A trigger frame is delivered to trigger a measurement result reporting procedure. This avoids a reporting failure when the measurement result is directly reported on the first narrowband channel.
