Abstract
Aspects of a method and system for a fast power control mechanism for Bluetooth devices may include receiving from a first Bluetooth device, a request for a transmit power adjustment for one or more operating modes. A step size may be received for the transmit power adjustment via the received request. The transmit power may be adjusted as a function of the step size. A feedback message may be sent to the first Bluetooth device, wherein the feedback message may indicate a status of the adjusting. The transmit power adjustment may be requested via a Link Management Protocol (LMP) message. One or more operating modes may comprise a Bluetooth Basic Rate (BR) mode, and/or a Bluetooth Enhanced Data Rate (EDR) mode.
Claims24
A method for communication, the method comprising:
- performing using one or more processors, one or more circuits, or any combination thereof in a second Bluetooth device:
- receiving from a first Bluetooth device, a request for a transmit power adjustment for one or more operating modes, the request including a one-byte reserved field that is reserved according to a Bluetooth specification for a transmit power adjustment request format;
- receiving a step size for said transmit power adjustment via said received request, the step size being encoded in the one-byte reserved field, wherein a first set of bits of the one-byte reserved field are employed for encoding the step size when the transmit power adjustment pertains to a Bluetooth Basic Rate (BR) mode, and a second set of bits of the one-byte reserved field are employed for encoding the step size when the transmit power adjustment pertains to a Bluetooth Enhanced Data Rate (EDR) mode;
- adjusting said transmit power as a function of said step size;
- and
- sending a feedback message to said first Bluetooth device, wherein said feedback message indicates a status of said adjusting.
A system for communication, the system comprising:
- one or more processors, one or more circuits, or any combination thereof in a second Bluetooth device, wherein said one or more processors, one or more circuits, or any combination thereof are operable to:
- receive from a first Bluetooth device, a request for a transmit power adjustment for one or more operating modes, the request including a one-byte reserved field that is reserved according to a Bluetooth specification for a transmit power adjustment request format;
- receive a step size for said transmit power adjustment via said received request, the step size being encoded in the one-byte reserved field, wherein a first set of bits of the one-byte reserved field are employed for encoding the step size when the transmit power adjustment pertains to a Bluetooth Basic Rate (BR) mode, and a second set of bits of the one-byte reserved field are employed for encoding the step size when the transmit power adjustment pertains to a Bluetooth Enhanced Data Rate (EDR) mode;
- adjust said transmit power as a function of said step size;
- and
- send a feedback message to said first Bluetooth device, wherein said feedback message indicates a status of said adjusting.
A system, comprising:
- means for receiving from a first Bluetooth device, a request for a transmit power adjustment for one or more operating modes, the request including a one-byte reserved field that is reserved according to a Bluetooth specification for a transmit power adjustment request format;
- means for receiving a step size for said transmit power adjustment via said received request, the step size being encoded in the one-byte reserved field, wherein a first set of bits of the one-byte reserved field are employed for encoding the step size when the transmit power adjustment pertains to a Bluetooth Basic Rate (BR) mode, and a second set of bits of the one-byte reserved field are employed for encoding the step size when the transmit power adjustment pertains to a Bluetooth Enhanced Data Rate (EDR) mode;
- means for adjusting said transmit power as a function of said step size;
- and
- means for sending a feedback message to said first Bluetooth device, wherein said feedback message indicates a status of said adjusting.
