Control apparatus having signal strength identification, method of controlling the same, and communication system

A method of controlling a system comprising a plurality of access points (APs), the method comprising:

• identifying a received signal strength at a station (STA) of signals transmitted from the plurality of APs;
• and
• determining communication parameters for the plurality of APs to communicate with the STA by using joint beamforming (JB),
• wherein, in the determining, after the received signal strength at the STA of a signal transmitted from a first AP and the received signal strength at the STA of a signal transmitted from a second AP are identified, it is determined whether to use JB for communication between the first AP and the second AP and the STA based on a strength difference between the two received signal strengths.

A control apparatus operable to control a plurality of access points (APs), comprising:

• at least one memory that stores a set of instructions;
• and
• at least one processor that executes the instructions to:
• obtain information on a received signal strength at a station (STA) of signals transmitted from the plurality of APs;
• and
• determine communication parameters for the plurality of APs to communicate with the STA by using joint beamforming (JB),
• wherein, after information on a received signal strength at the STA of a signal transmitted from a first AP and information on a received signal strength at the STA of a signal transmitted from a second AP are obtained, whether to use JB for communication between the first AP and the second AP and the STA is determined based on a strength difference between the two received signal strengths.

An access point (AP) apparatus, which performs wireless communication based on standards of IEEE 802.11 series, comprising:

• at least one memory that stores a set of instructions;
• and
• at least one processor that executes the instructions to:
• obtain information on a received signal strength between another AP apparatus and a station (STA) and information on a received signal strength between the AP apparatus and the STA;
• and
• determine communication parameters for a plurality of APs to communicate with the STA by using joint beamforming (JB) wherein, after the information on the received signal strength at the STA of the signal transmitted from the other AP and the information on the received signal strength at the STA of the signal transmitted from the AP are obtained, it is determined whether to use JB for communication between the AP and the other AP and the STA based on a strength difference between the two received signal strengths.
