Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/093369
Kind Code:
A1
Abstract:
Embodiments of the present application provide a communication method and a communication apparatus. In the method, a low-power wake-up signal sent by a network device comprises a plurality of OFDM symbols, each OFDM symbol carries a plurality of OOK symbols, and each OOK symbol corresponds to a time domain sequence. The time domain sequence corresponding to each OOK symbol can realize frequency domain amplitude randomization; therefore, a frequency spectrum is relatively dispersed after the time domain sequence is transformed to a frequency domain, the situation that the frequency spectrum is excessively concentrated is avoided, and the influence caused by frequency selective fading can be avoided, thereby improving the receiving performance of the low-power wake-up signal of a receiving end.
