AI Technical Summary

Problems solved by technology

Narrowband wireless devices may always receive trigger frames or TF-Rs on the same frequency, which limits frequency domain flexibility, or may scan different frequencies to locate trigger frames or TF-Rs
However, this means scanning for a trigger frame or TF-R on a fixed frequency or waiting for a trigger frame or TF-R consumes unnecessary power in narrowband wireless devices

Abstract

The present application relates to a wireless device utilizing a wake-up signal with frequency information and a method of operating the same. According to a method for operating a first wireless device (100) in a wireless network, at least one target wireless device (200) that should receive a wake-up signal is determined, by means of the wake-up signal, sending a message to the at least one target wireless device The wake-up receiver notifies the target wireless device's master transceiver that it should be ready to receive at least a first message from the first wireless device. In addition, determining the frequency at which the at least first message should be sent to the at least one target wireless device, and encoding frequency information into the wake-up signal, by means of which frequency information, the at least one target wireless device is notified that it will receive said frequency of said at least first message. The wake-up signal with the encoded frequency information is sent to the at least one target wireless device.

Description

technical field [0001] The present application relates to a method for operating a first wireless device in a wireless network to send a wake-up signal to a target wireless device. Furthermore, the present application relates to a method for operating a target wireless device and a corresponding first wireless device and the target wireless device. Furthermore, a system, computer program and carrier comprising a target wireless device and a first wireless device are provided. Background technique [0002] Wake-up receivers (WUR) are known in the art, which enable power-efficient data reception with only slightly increased delay. A low power wake-up receiver can be provided in addition to the main transceiver, which is turned off unless there is something to transmit or receive. The wake-up receiver wakes up the master transceiver when it has a message to receive. The message can be a data message or a control message. The main transceiver is used for data transmission an...
