Abstract

Various solutions for wake-up signal and preamble design for mobile communications are described. An apparatus, while in a first mode of operation, receives a wake-up signal (WUS) from a network. In response to receiving the WUS, the apparatus switches to a second mode of operation from the first mode of operation. The apparatus then detects a preamble in downlink (DL) transmissions from the network. In response to detecting the preamble, the apparatus monitors a physical downlink control channel (PDCCH) to check for an uplink (UL) transmission grant for the apparatus from the network.
