Abstract
A communication apparatus, which operates as a master access point in a wireless network including one or more other access points operating as slaves and one or more stations, generates a trigger frame that includes a Trigger type subfield value indicating an instruction to perform cooperative transmission with the other access points, transmits the generated trigger frame to the other access points, and executes the cooperative transmission with the other access points to which the trigger frame has been transmitted.
Claims18
A communication apparatus that operates as a master access point in a wireless network that includes another communication apparatus operating as a slave access point and a station, the communication apparatus comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processing circuit,
- wherein the communication apparatus is caused, by at least one of the at least one processing circuit executing the instructions or the at least one processing circuit operating, to perform operations comprising:
- generating a trigger frame that is used for triggering a coordinated transmission with the other communication apparatus and includes a User Info field for the other communication apparatus operating as the slave access point;
- transmitting the trigger frame to the other access point operating as the slave access point;
- and
- executing the coordinated transmission with the other access point to which the trigger frame has been transmitted.
A wireless communication system in which a plurality of access points and one or more stations constitute a wireless network, wherein one access point out of the plurality of access points operates as a master access point, and another access point out of the plurality of access points operates as a slave access point, the master access point comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processing circuit,
- wherein the master access point in the wireless communication system is caused, by at least one of the at least one processing circuit executing the instructions or the at least one processing circuit operating, to perform operations comprising:
- generating a trigger frame that is used for triggering a coordinated transmission with the slave access point and includes a User Info field for the slave access point;
- transmitting the trigger frame to the slave access point;
- and
- executing the coordinated transmission with the slave access point that has received the trigger frame to the one or more stations.
A controlling method for controlling an access point that operates as a master access point of a wireless network that includes one or more other access points operating as slave access points and one or more stations, the method comprising:
- generating a trigger frame that is used for triggering a coordinated transmission with an access point operating as the slave access point and includes a User Info field for the access point operating as the slave access point;
- transmitting the trigger frame to the access point operating as the slave access point;
- and
- executing the coordinated transmission with the other access points to which the trigger frame has been transmitted.
A non-transitory computer-readable storage medium storing a program for causing a computer to perform a controlling method for controlling an access point that operates as a master access point of a wireless network that includes one or more other access points operating as slave access points and one or more stations, the method comprising:
- generating a trigger frame that is used for triggering a coordinated transmission with an access point operating as the slave access point and includes a User Info field for the access point operating as the slave access point;
- transmitting the trigger frame to the access point operating as the slave access point;
- and
- executing the coordinated transmission with the other access points to which the trigger frame has been transmitted.
A communication apparatus that operates as a slave access point in a wireless network that includes another communication apparatus operating as a master access point and one or more stations, the apparatus comprising:
- at least one memory that stores a set of instructions;
- and
- at least one processing circuit,
- wherein the communication apparatus is caused, by at least one of the at least one processing circuit executing the instructions or the at least one processing circuit operating, to perform operations comprising:
- receiving, from the other communication apparatus operating as the master access point, a trigger frame that is used for triggering a coordinated transmission with the other communication apparatus operating as the master access point and includes a User Info field for the communication apparatus operating as the slave access point;
- and
- executing, with the other communication apparatus as the master access point, the coordinated transmission to the one or more stations, based on the received trigger frame.
A control method for controlling an access point that operates as a slave access point of a wireless network that includes other access point operating as a master access point and one or more stations, the method comprising:
- receiving, from the other access point operating as the master access point, a trigger frame that is used for triggering a coordinated transmission with the other access point operating as the master access point and includes a User Info field for the access point operating as the slave access point;
- and
- executing, with the other access point as the master access point, the coordinated transmission to the one or more stations, based on the received trigger frame.
A non-transitory computer-readable storage medium storing a program for causing a computer to perform an access point control method for controlling an access point that operates as a slave access point and constitutes a wireless network that includes another access point operating as a master access point and one or more stations, the method comprising:
- receiving, from the other access point operating as the master access point, a trigger frame that is used for triggering a coordinated transmission with the other access point operating as the master access point and includes a User Info field for the access point operating as the slave access point;
- and
- executing, with the other access point as the master, the coordinated transmission to the one or more stations, based on the received trigger frame.
