Title:

METHODS AND DEVICES FOR WAKE-UP SIGNAL

Document Type and Number:

WIPO Patent Application WO/2023/230989

Kind Code:

A1

Abstract:

Embodiments of the present disclosure relate to methods and devices for wake-up signals. A method implemented at a network device comprises forming an OOK subsequence with multiple OOK symbols that comprise at least one OOK ON-symbol and at least one OOK OFF-symbol. The multiple OOK symbols are associated with one OFDM symbol. The method further comprises mapping the OOK subsequence into multiple pre-Discrete Fourier Transform (pre-DFT) subsequences respectively to form a pre-DFT sequence, and performing transform precoding on the pre-DFT sequence. The method further comprises mapping output of the transform precoding into frequency resources allocated to a Wake-up Signal (WUS) and generating the WUS, and transmitting to a terminal device the WUS.
