Inventors include Gan, Ming; and Hu, Mengshi.
The application for the patent was published on September 18, 2026, under issue no. 38/2026.
Abstract: The present application relates to the technical field of communications. Disclosed are a communication method, apparatus and system. The method comprises: a first communication apparatus generating one or more OFDM symbols in a radio frame; and transmitting the one or more OFDM symbols on a first channel in a first frequency band, wherein a subcarrier spacing of the first channel is 2N times a subcarrier spacing of a second channel in a second frequency band, the subcarrier spacing of the second channel is 480 kHz, and the lowest frequency of the first frequency band is higher than the highest frequency of the second frequency band; and the bandwidth of the second channel is 2P*20 MHz, and the bandwidth of the first channel is 2N*2P*20 MHz. By means of the method, parameters of a high-frequency band are designed on the basis of those of a low-frequency band, such that a subcarrier spacing of the high-frequency band is larger than that of the low-frequency band, thus facilitating overcoming effects such as more prominent phase noise of the high-frequency band, and thereby improving the transmission performance.
