Abstract
Methods and systems for synchronizing carrier frequency of multiple access points. A method includes receiving a first frame from a second AP device. The method also includes estimating a frequency pre-correction value based on the received signal of the first frame. The method also includes adjusting a frequency for a second frame to be transmitted following reception of the first frame based on the frequency pre-correction value. The method also includes transmitting the second frame based on the adjusted frequency.
Claims20
A method performed by a first access point (AP) device, the method comprising:
- receiving a first frame from a second AP device;
- estimating a frequency pre-correction value based on a received signal of the first frame;
- adjusting a frequency for a second frame to be transmitted following reception of the first frame based on the frequency pre-correction value;
- and
- transmitting the second frame based on the adjusted frequency.
A method performed by a second access point (AP) device in response to a first AP device, the method comprising:
- transmitting a first frame to the first AP device;
- receiving a second frame with a first adjusted frequency;
- estimating a frequency pre-correction value based on the received signal of the second frame;
- adjusting a second frequency for a third frame to be transmitted following reception of the second frame based on the frequency pre-correction value;
- and
- transmitting the third frame based on the adjusted second frequency.
An electronic device comprising:
- at least one processor including processing circuitry;
- and
- a memory storing instructions, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to:
- receive a first frame from a second AP device;
- estimate a frequency pre-correction value based on the received signal of the first frame;
- adjust a frequency for a second frame to be transmitted following reception of the first frame based on the frequency pre-correction value;
- and
- transmit the second frame based on the adjusted frequency.
