Abstract
A communication apparatus operable to act as a master-AP in a multi-AP (access point) coordination configuration that supports an IEEE802.11 series standard, selects a sounding method which is a method for transmitting a sounding packet for receiving a CSI report as feedback from a terminal apparatus in accordance with a CSI (channel state information) calculation capability in the terminal apparatus that is connected to the communication apparatus.
Claims14
A communication apparatus operable to act as a master-AP in a multi-AP (access point) coordination configuration, the apparatus comprising:
- a selection unit configured to select a sounding method from a plurality of sounding method at least including a first sounding method and a second sounding method which is a method for transmitting a sounding packet for receiving a CSI report as feedback from a terminal apparatus that is connected to the communication apparatus;
- a performing unit configured to execute first sounding process in a case where the first sounding method is selected by the selection unit and execute a second sounding process in a case where the second sounding method is selected by the selection unit;
- and
- a reception unit configured to receive a predetermined frame from the terminal apparatus,
- wherein, in a case where a value indicating a CSI calculation capability, which is indicated by two or more values, is included in the received predetermined frame, the selection unit selects the sounding method based on the received value indicating the CSI calculation capability.
A method of controlling a communication apparatus operable to act as a master-AP in a multi-AP (access point) coordination configuration, the method comprising:
- selecting a sounding method from a plurality of sounding method at least including a first sounding method and a second sounding method which is a method for transmitting a sounding packet for receiving a CSI report as feedback from a terminal apparatus in accordance with a CSI (channel state information) calculation capability in the terminal apparatus that connected to the communication apparatus;
- transmitting a first sounding packet in a case where the first sounding method is selected and transmit a second sounding packet in a case where the second sounding method is selected and
- receiving a predetermined frame from the terminal apparatus,
- wherein, in a case where a value indicating a CSI calculation capability, which is indicated by two or more values, is included in the received predetermined frame, the sounding method is selected based on the received value indicating the CSI calculation capability.
A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a method for controlling a communication apparatus acting as a master-AP in a multi-AP (access point) coordination configuration, the method comprising:
- selecting a sounding method from a plurality of sounding method at least including a first sounding method and a second sounding method which is a method for transmitting a sounding packet for receiving a CSI report as feedback from a terminal apparatus that connected to the communication apparatus;
- transmitting a first sounding packet in a case where the first sounding method is selected and transmit a second sounding packet in a case where the second sounding method is selected and
- receiving a predetermined frame from the terminal apparatus,
- wherein, in a case where a value indicating a CSI calculation capability, which is indicated by two or more values, is included in the received predetermined frame, the sounding method is selected based on the received value indicating the CSI calculation capability.
