Abstract
A communication apparatus complying with an IEEE802.11 series standard, determines, based on information received from another communication apparatus connected to the communication apparatus, whether UL MU (Uplink Multiuser) communication of the other communication apparatus is enabled or disabled, acquires, from the other communication apparatus by a method according to a result of the determination, a BQR (Bandwidth Query Report) representing a state of a communication resource usable by the other communication apparatus, and decides the communication resource used to communicate with the other communication apparatus based on the acquired BQR.
Claims10
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.
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.
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.
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.
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.
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.
