## Abstract

A communication apparatus that wirelessly communicates with a partner apparatus performs, based on information related to a distance between another communication apparatus and the partner apparatus, determination of whether to execute cooperative communication of operating to reduce influence of interference between communication between the communication apparatus and the partner apparatus, and communication with the other communication apparatus, and controls communication based on a result of the determination.

## Claims

### Claim 1

A communication apparatus that performs communication using a radio frame compliant with IEEE802.11 standard with a partner apparatus, comprising:
a determination unit configured to perform, based on information about a distance between another communication apparatus and the partner apparatus, determination of whether to execute cooperative communication of operating to reduce influence of interference between communication between the communication apparatus and the partner apparatus, and communication with the other communication apparatus; and
a control unit configured to control communication based on a result of the determination.

### Claim 2 (depends on 1)

The communication apparatus according to claim 1, wherein the information about the distance includes information of a reception strength of a signal between the partner apparatus and the other communication apparatus.

### Claim 3 (depends on 1)

The communication apparatus according to claim 1, wherein the information about the distance includes information of a reception strength of a signal between the communication apparatus and the other communication apparatus.

### Claim 4 (depends on 1)

The communication apparatus according to claim 1, wherein the information about the distance includes channel state information between the partner apparatus and the other communication apparatus.

### Claim 5 (depends on 1)

The communication apparatus according to claim 1, wherein the information about the distance includes information of a positioning result in each of the partner apparatus and the other communication apparatus.

### Claim 6 (depends on 1)

The communication apparatus according to claim 1, wherein in a case where the cooperative communication is determined to be executed, the control unit performs control of causing the other communication apparatus to execute null steering for reducing interference with the partner apparatus.

### Claim 7 (depends on 6)

The communication apparatus according to claim 6, wherein in a case where the cooperative communication is determined to be executed, the control unit performs controls of executing null steering for reducing interference with a partner apparatus of the other communication apparatus.

### Claim 8 (depends on 1)

The communication apparatus according to claim 1, wherein the communication apparatus and the other communication apparatus are access points.

### Claim 9

A control method executed by a communication apparatus that performs communication using a radio frame compliant with IEEE802.11 standard with a partner apparatus, comprising:
performing, based on information about a distance between another communication apparatus and the partner apparatus, determination of whether to execute cooperative communication of operating to reduce influence of interference between communication between the communication apparatus and the partner apparatus, and communication with the other communication apparatus; and
controlling communication based on a result of the determination.

### Claim 10

A non-transitory computer-readable storage medium that stores a computer-readable storage medium that stores a program for causing a communication apparatus that performs communication using a radio frame compliant with IEEE802.11 standard with a partner apparatus to perform a control method, wherein the control method comprising:
performing, based on information about a distance between another communication apparatus and the partner apparatus, determination of whether to execute cooperative communication of operating to reduce influence of interference between communication between the communication apparatus and the partner apparatus, and communication with the other communication apparatus; and
controlling communication based on a result of the determination.
