Wireless device and wireless system
First Claim
1. A wireless device for use in a wireless communication network including at least one or more neighboring wireless devices with which the wireless device can communicate directly, the wireless device being operable in a first mode and a second mode, the wireless device relaying communications between the neighboring wireless devices in the first mode but not in the second mode, the wireless device comprising:
- a power controller for performing power control in the wireless device in different ways, depending on whether or not the wireless device operates in the first mode or the second mode;
a transmitter controlled by the power controller to transmit mode information and data to the neighboring wireless devices, the transmitted mode information indicating whether the wireless device is operating in the first mode or the second mode;
a receiver controlled by the power controller to receive mode information and data from the neighboring wireless devices, the received mode information indicating whether the neighboring wireless devices are operating in the first mode or the second mode;
a storage facility for storing the received mode information; and
a mode controller for deciding whether to have the wireless device operate in the first mode or the second mode, depending at least on the presence of a neighboring wireless device operating in the first mode, as indicated by the stored mode information.

Abstract
A wireless device operates in a first mode, in which it relays communications between neighboring wireless devices, and a second mode, in which it does not relay communications. The wireless device periodically transmits information indicating its operating mode to the neighboring wireless devices. In the first mode, when not transmitting mode information or communication data, the wireless device stands by with its receiver powered, ready to receive mode information or communication data from neighboring wireless devices. In the second mode, the wireless device is normally in a sleep state and wakes up only at scheduled intervals to transmit and receive mode information and communication data. The wireless device stores the received mode information and selects its operating mode according to the stored mode information, selecting the second mode when this does not prevent the prevent communication with or among the neighboring wireless devices.
