Abstract:
Methods, systems, and devices for wireless communication are described. A transmitting device may transmit a wakeup message to another device. The wakeup message may be transmitted using a transmit diversity scheme in accordance with aspects of the present disclosure. The transmit diversity may, for example, include a cyclic shift diversity scheme, a phase rotation scheme, a symbol generation scheme, or combinations thereof. The transmit diversity may in some cases improve a communication range of the wakeup message or otherwise benefit the wireless communications system.
