Communication apparatus, control method of communication apparatus, and non-transitory computer-readable storage medium

1. An access point apparatus complying with an IEEE802.11 series standard, comprising:

one or more processors; and

one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the access point apparatus to:

determine, based on information received from a station apparatus connected to the access point apparatus, whether a UL MU (Uplink Multiuser) communication function is enabled or disabled in the station apparatus;

acquire, from the station apparatus, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the station apparatus, either by transmitting a BQR poll (BQRP) to the station apparatus in a case where the UL MU communication function is enabled in the station apparatus or by waiting the BQR from the station apparatus without transmitting the BQRP to the station apparatus in a case where the UL MU communication function is disabled in the station apparatus; and

decide the communication resource used to communicate with the station apparatus based on the acquired BQR.

2. The access point apparatus according to claim 1 , wherein in a case where information representing that the BQR is supported, and the BQR is enabled, is received from the station apparatus, the access point apparatus transmits the trigger frame.

3. The access point apparatus according to claim 1 , wherein in a case where information representing that the UL MU communication is supported, and the UL MU communication is enabled, is received from the station apparatus, the access point apparatus determines that the UL MU communication function of the station apparatus is enabled, and otherwise, determines that the UL MU communication function of the station apparatus is disabled.

4. The apparatus according to claim 1 , wherein when the access point apparatus performs coordination communication with another access point apparatus by coordinately using a predetermined frequency band, the access point apparatus decides the communication resource used to communicate with the station apparatus and the other access point apparatus based on the BQR acquired from the station apparatus and a BQR acquired from the other access point apparatus.

5. A control method of an access point apparatus complying with an IEEE802.11 series standard, comprising:

determining, based on information received from a station apparatus connected to the access point apparatus, whether a UL MU (Uplink Multiuser) communication function is enabled or disabled in the station apparatus;

acquiring, from the station apparatus, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the station apparatus, either by transmitting a BQR poll (BQRP) to the station apparatus in a case where the UL MU communication function is enabled in the station apparatus or by waiting the BQR from the station apparatus without transmitting the BQRP to the station apparatus in a case where the UL MU communication function is disabled in the station apparatus; and

deciding the communication resource used to communicate with the station apparatus based on the acquired BQR.

6. The station apparatus according to claim 5 , wherein the computer-readable instruction causes, when executed by the one or more processors, the station apparatus to receive a trigger frame for requesting transmission of the BQR,

wherein in a case where it is notified that the UL MU communication function is enabled, the station apparatus transmits the BQR to the access point apparatus in accordance with reception of the trigger frame.

7. A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a control method of an access point apparatus complying with an IEEE802.11 series standard, the method comprising:

determining, based on information received from a station apparatus connected to the access point apparatus, whether a UL MU (Uplink Multiuser) communication function is enabled or disabled in the station apparatus;

acquiring, from the station apparatus, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the station apparatus, either by transmitting a BQR poll (BQRP) to the station apparatus in a case where the UL MU communication function is enabled in the station apparatus or by waiting the BQR from the station apparatus without transmitting the BQRP to the station apparatus in a case where the UL MU communication function is disabled in the station apparatus; and

deciding the communication resource used to communicate with the station apparatus based on the acquired BQR.

8. A station apparatus complying with an IEEE802.11 series standard, comprising:

one or more processors; and

one or more memories that store a computer-readable instruction for causing, when executed by the one or more processors, the station apparatus to:

determine whether the station apparatus enables or disables a UL MU (Uplink Multiuser) communication function;

make a notification based on a result of the determination to an access point apparatus to which the station apparatus is connected; and

transmit, to the access point apparatus, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the station apparatus after the notification, either in response to reception of a BQR poll (BQRP) from the access point apparatus in a case where the UL MU communication function is enabled, or without reception of the BQRP from the access point apparatus in a case where the UL MU communication function is disabled.

9. A control method of a station apparatus complying with an IEEE802.11 series standard, comprising:

determining whether the station apparatus enables or disables a UL MU (Uplink Multiuser) communication function;

performing a notification based on a result of the determination to an access point apparatus to which the station apparatus is connected; and

transmitting, to the access point apparatus, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the station apparatus after the notification, either in response to reception of a BQR poll (BQRP) from the access point apparatus in a case where the UL MU communication function is enabled, or without reception of the BQRP from the access point apparatus in a case where the UL MU communication function is disabled.

10. A non-transitory computer-readable storage medium storing a computer program for causing a computer to execute a control method of a station apparatus complying with an IEEE802.11 series standard, the method comprising:

determining whether the station apparatus enables or disables a UL MU (Uplink Multiuser) communication function;

performing a notification based on a result of the determination to an access point apparatus to which the station apparatus is connected; and

transmitting, to the access point apparatus, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the station apparatus after the notification, either in response to reception of a BQR poll (BQRP) from the access point apparatus in a case where the UL MU communication function is enabled, or without reception of the BQRP from the access point apparatus in a case where the UL MU communication function is disabled.
