Abstract: Systems and methods of transmitting and receiving a Wake-Up Radio (WUR) packet by using a simplified preamble structure that contains no training field. The preamble carries a signature sequence selected from a set of predefined sequences, each corresponding to a different data transmission rate. The preamble and the control information of the WUR packet are transmitted in the same rate as indicated by the selected sequence. Hence, a receiving WUR can determine the data transmission rate and locate the associated control information directly if a sequence that matches a predefined signature sequence is detected. The same sequence or in combination with an additional sequence in the preamble may also be used to indicate automatic gain control synchronization, packet type and other related information.
