Abstract
Methods and apparatus of varying transmit power of signals for increasing system throughput and spectral reuse in an unlicensed spectrum are disclosed. One method includes transmitting from a first mobile device to a second mobile device a request to send (RTS) signal having a first transmit data power level based on a channel gain between the first mobile device and the second mobile device, receiving, at the first mobile device, a clear to send (CTS) signal from the second mobile device, and transmitting data at the first transmit data power level from the first mobile device to the second mobile device.
Claims48
A method of increasing system throughput in an unlicensed spectrum comprising:
- transmitting from a first mobile device to a second mobile device a first request to send (RTS) signal having a first transmit data power level based on a channel gain between the first mobile device and the second mobile device;
- receiving, at the first mobile device, a first clear to send (CTS) signal from the second mobile device;
- and
- transmitting data at the first transmit data power level from the first mobile device to the second mobile device.
An apparatus for increasing system throughput in an unlicensed spectrum comprising:
- a processor configured to:
- transmit from a first mobile device to a second mobile device a first request to send (RTS) signal having a first transmit data power level based on a channel gain between the first mobile device and the second mobile device;
- receive, at the first mobile device, a first clear to send (CTS) signal from the second mobile device;
- and
- transmit data at the first transmit data power level from the first mobile device to the second mobile device.
An apparatus for increasing system throughput in an unlicensed spectrum comprising:
- means for transmitting from a first mobile device to a second mobile device a first request to send (RTS) signal having a first transmit data power level based on a channel gain between the first mobile device and the second mobile device;
- means for receiving, at the first mobile device, a first clear to send (CTS) signal from the second mobile device;
- and
- means for transmitting data at the first transmit data power level from the first mobile device to the second mobile device.
A machine readable medium embodying machine executable instructions to implement a method of increasing system throughput in an unlicensed spectrum, the method comprising:
- transmitting from a first mobile device to a second mobile device a first request to send (RTS) signal having a first transmit data power level based on a channel gain between the first mobile device and the second mobile device;
- receiving, at the first mobile device, a first clear to send (CTS) signal from the second mobile device;
- and
- transmitting data at the first transmit data power level from the first mobile device to the second mobile device.
