Abstract
Methods and systems for waking up an electronic device having a wake-up receiver circuit. A signal is transmitted, carrying a wake-up frame (WUF) including a protocol data unit (PDU). A wake-up sequence is inserted in a portion ahead of the PDU. The wake-up sequence is used by the electronic device for detection of the WUF and identification of the intended recipient. The WUF also includes a wake-up identifier (WUID) that is used by the electronic device to authenticate the WUF.
Claims22
A method of waking up a electronic device (ED) having a wake-up receiver circuit, the method comprising:
- transmitting a signal comprising a wake-up frame (WUF) within a physical protocol data unit (PPDU);
- wherein the WUF includes a wake-up sequence inserted in a portion within the PPDU, the wake-up sequence encoding information for detection of the WUF and identification of at least one intended recipient device;
- and
- wherein the WUF further includes a wake-up identifier (WUID) in a data portion following the wake-up sequence, the WUID encoding information for authenticating the WUF.
A method of waking up an electronic device (ED)having a wake-up receiver circuit, the method comprising:
- receiving a signal comprising a wake-up frame (WUF);
- decoding a first portion of the WUF to obtain a received wake-up sequence and performing correlation on the received wake-up sequence;
- after successful correlation, decoding a second portion of the WUF to obtain a wake-up identifier (WUID) and validating authentication of the WUID;
- and
- after successful validation, transmitting an internal signal to a main receiver circuit to wake up the ED.
An electronic device (ED)comprising a wake-up receiver circuit configured to:
- receive a signal comprising a wake-up frame (WUF);
- decode a first portion of the WUF to obtain a received wake-up sequence and perform correlation on the received wake-up sequence;
- after successful correlation, decode a second portion of the WUF to obtain a wake-up identifier (WUID) and validating authentication of the WUID;
- and
- after successful validation, transmit an internal signal to a main receiver circuit to wake up the ED.
