Title:
COMMUNICATION APPARATUS AND COMMUNICATION METHOD FOR MODE AGNOSTIC RECEPTION
Document Type and Number:
WIPO Patent Application WO/2019/049576
Kind Code:
A1
Abstract:
The present disclosure provides a communication apparatus that comprises a transmission signal generator which, in operation, generates a first transmission signal of a first signal type (Orthogonal Frequency Division Multiplexing (OFDM) modulation) and a second transmission signal of a second signal type (ON-OFF Keying (OOK) modulation), wherein the first transmission signal is comprised of a legacy 802.11 preamble followed by a WUR Mark field made up of one or more OFDM symbols, the second transmission signal is comprised of a wakeup preamble and a wakeup radio (WUR) payload, the said WUR Mark field carries information regarding the second transmission signal; and a transmitter which, in operation, transmits the first transmission signal followed immediately by the second transmission signal.
