Publication number: 20240114454Abstract: Various solutions for low-power wake-up signal (LP-WUS) design with respect to user equipment and network node in mobile communications are described. An apparatus may receive a LP-WUS configuration from a network node. The apparatus may receive a LP-WUS based on the LP-WUS configuration from the network node. The apparatus may determine whether to wake up according to the LP-WUS. The LP-WUS with N subcarriers (SCs) is generated through a transformation of M-bit on-off keying (OOK) in a time domain. The transformation is a discrete Fourier transform (DFT) or least square operation. K samples are generated from the M bits with a signal modification or a signal truncation. The LP-WUS is generated through an inverse fast Fourier transform (IFFT) operation. The K is a size of the IFFT operation of cyclic-prefix orthogonal frequency-division multiple access (CP-OFDMA). The N is less than or equal to the K.Type: ApplicationFiled: August 22, 2023Publication date: April 4, 2024Inventors: Chien-Chun Cheng, Wei-De Wu, Yi-Ju Liao
