Embodiment Construction

[0016] overview

[0017] An embodiment of the present invention provides control of communication transmit power using power control messages of selectable sizes and allows for flexible power control while also minimizing the amount of data required to transmit the control messages.

[0018] According to one embodiment of the invention, the first radio transceiver sends a signal to the second radio transceiver. The second radio transceiver sends a message to the first radio transceiver based at least in part on the quality of the received signal, the message including a request to modify the transmit power of the first radio transceiver or an indication of signal quality for power control Deviated power control messages. The power control message is a message of a size optionally selected by the second radio transceiver. According to one embodiment, the power control message comprises a first part and optionally an additional second part which is included when the first pa...

Abstract

According to an embodiment of the invention, a method and apparatus are described to receive a signal, determine a quality of the received signal, and transmit a power control message, with a selected size, the power control message being based at least in part on the quality of the received signal. The power control message requests a modification in transmission power or indicates the deviation of the signal quality from a reference signal quality. In one embodiment the power control message comprises a basic power control message and an optional extended power control message.

Description

[0001] related application [0002] This application is a continuation-in-part of US Patent Application Serial No. 10 / 189,709, filed July 3, 2002, and entitled "Selective Power Control Information Transfer." technical field [0003] The present invention relates generally to the field of wireless communications. More specifically, the present invention relates to selective power control messaging. Background technique [0004] In wireless communications, it is desirable to transmit signals with a minimum transmit power output that still provides the desired signal quality and reliable communications. Reducing transmit power to a minimum conserves transmitter power, which will allow improved battery life for portable devices as well as better power sharing and lower operating costs in the case of multi-carrier transmitters. Furthermore, minimizing transmit power output reduces the amount of electromagnetic power introduced into the radio frequency environment. Excess trans...
