Adaptive thresholding in a Wake-On-Radio system
First Claim
1. A method for setting a transmit power level of a transmitter for a wake-on-radio (WOR) system comprising a transmitter for sending wake-up messages and a WOR receiver for receiving such wake-up messages, the method comprising:
- setting the transmit power level of a transmitter for sending wake-up messages at a low level;
setting a wake threshold of a WOR receiver;
the receiver sending a report of false crossings of said wake threshold;
the transmitter for sending wake-up messages receiving said report of false crossings of said wake threshold from said WOR receiver;
the transmitter for sending wake-up messages computing a value based on the false crossings reported by the WOR receiver;
the transmitter for sending wake-up messages modifying the transmit power level of the transmitter for sending wake-up messages based, at least in part, on the value; and
the transmitter for sending wake-up messages using said modified transmit power to send a wake-up message to said WOR receiver.

Abstract
A method for modifying a wake threshold for a wake-on-radio (WOR) receiver including: setting the wake threshold at a first level, counting false crossings of the wake threshold, and optionally modifying the wake threshold level based, at least in part, on a result of the counting. A receiver in a wake-on-radio (WOR) system including a wake-on-radio unit configured to implement the method for modifying a wake threshold. A method for setting a transmit power level of a transmitter for a wake-on-radio (WOR) system transmitter including: setting the level at a low level, receiving reports of false crossings of a wake threshold from a WOR receiver, and counting false crossings reported by the WOR receiver, and optionally modifying the transmit power level based, at least in part, on a result of the counting. A transmitter in a wake-on-radio (WOR) system including a transmit power adapter configured to implement the above method. Related apparatus and methods are also described.

14. A wake-on-radio (WOR) system comprising:
-
a WOR receiver configured to send reports of false crossings of a wake threshold to a transmitter for sending wake-up messages; and said transmitter for sending wake-up messages configured; to set the transmit power level of said transmitter for sending wake-up messages at a low level; to receive a report of false crossings of said wake threshold from said WOR receiver; to compute a value based on said report of false crossings of said wake threshold from said WOR receiver; and to modify a transmit power level based, at least in part, on a result of said value; and to send a wake-up message at said modified transmit power level to said WOR receiver. - View Dependent Claims (15, 16, 17)
