Energy-efficient detection of network connection requests
First Claim
1. A method implemented by a wireless device for detecting requests to connect to a wireless communications network, the method characterized by:
- determining a receiver sensitivity that is sufficient, given channel conditions at the device, for the device to detect said requests;
dynamically selecting, from among different receiver sensitivity configurations of the device, a configuration that has a receiver sensitivity at least as good as the determined receiver sensitivity and that has less energy consumption than at least one other configuration;
using the selected configuration to detect said requests; and
listening for said requests over a first frequency when using a first one of the receiver sensitivity configurations, and listening for said requests over a second frequency using a second one of the receiver sensitivity configurations.

Abstract
Embodiments herein include a method implemented by a wireless device for detecting requests to connect to a wireless communications network. The method includes determining a receiver sensitivity that is sufficient, given channel conditions at the device, for the device to detect connection requests. The method then entails dynamically selecting, from among different receiver sensitivity configurations of the device, a configuration that has a receiver sensitivity at least as good as the determined sensitivity and that has less energy consumption than at least one other configuration. Finally, the method includes using the selected configuration for request detection. A wireless device herein thereby reduces its energy consumption when it is disconnected from the network, but intelligently limits the extent of that energy consumption reduction in order to maintain an ability to detect network connection requests.

21. A method implemented by a wireless node for requesting a wireless device to connect to a wireless communications network, the method comprising:
-
generating, using a first set of transmit parameters, a first connection request signal targeted for receipt by the wireless device at a first receiver sensitivity; generating, using a second set of transmit parameters different from the first set, a second connection request signal targeted for receipt by the wireless device at a second receiver sensitivity different from the first receiver sensitivity; and transmitting the first and second connection request signals to the wireless device for requesting that the device connect to the network; wherein said generating and transmitting are performed without having obtained information indicating a receiver sensitivity that is or is not sufficient, given channel conditions at the device, for the device to detect the first and second connection request signals. - View Dependent Claims (22, 23, 24, 25)

26. A wireless node configured to request a wireless device to connect to a wireless communications network, the node comprising one or more transmitters and one or more processing circuits configured to:
-
generate, using a first set of transmit parameters, a first connection request signal targeted for receipt by the wireless device at a first receiver sensitivity; generate, using a second set of transmit parameters different from the first set, a second connection request signal targeted for receipt by the wireless device at a second receiver sensitivity different from the first receiver sensitivity; and transmit the first and second connection request signals to the wireless device for requesting that the device connect to the network; wherein the one or more processing circuits are configured to perform said generating and transmitting without having obtained information indicating a receiver sensitivity that is or is not sufficient, given channel conditions at the device, for the device to detect the first and second connection request signals. - View Dependent Claims (27, 28, 29, 30)
