Communication apparatus, control method for communication apparatus, and computer-readable storage medium

1 . A communication apparatus complying with an IEEE 802.11 series standard, comprising:

one or more processors; and

a memory storing instructions that, when executed by the one or more processors, cause the communication apparatus to:

receive a frame for requesting a TWT (Target Wake Time) operation from a first other communication apparatus among a plurality of other communication apparatuses connected to the communication apparatus;

determine whether the frame is a frame for periodic Low Latency communication; and

perform a predetermined notification so as to limit a time length of a transmission frame by a second other communication apparatus different from the first other communication apparatus among the plurality of other communication apparatuses, in a case where it is determined that the frame is the frame for the Low Latency communication,

wherein information corresponding to attributes of the Low Latency communication decided by the first other communication apparatus is set in the frame for the Low Latency communication,

wherein the attributes of the Low Latency communication include a start time of the Low Latency communication, a permissible delay time in the Low Latency communication, and a minimum communication data amount in the Low Latency communication.

2 . The communication apparatus according to claim 1 , wherein the predetermined notification is performed by transmitting a Beacon frame that designates a value, which is not larger than a value of a TWT wake Interval decided with the first other communication apparatus based on the frame for requesting a TWT, as the value of a TXOP (Transmission Opportunity) limit representing a maximum transmittable time to the second other communication apparatus.

3 . The communication apparatus according to claim 1 , further setting a TXOP (Transmission Opportunity) limit with respect to the communication apparatus after the predetermined notification is performed,

wherein a value, which is not smaller than a duration of a TWT SP (Service Period) decided with the first other communication apparatus based on the frame for requesting a TWT, is set as the value of the TXOP limit representing a maximum transmittable time to the communication apparatus.

4 . The communication apparatus according to claim 1 , wherein in a case where the frame is not determined to be a frame for power saving, the frame is determined to be the frame for the Low Latency communication.

5 . The communication apparatus according to claim 4 , wherein whether or not the frame is intended for power saving is determined based on a value of a Power Management field included in the frame.

6 . A control method for a communication apparatus complying with an IEEE 802.11 series standard, comprising:

receiving a frame for requesting a TWT (Target Wake Time) operation from a first other communication apparatus among a plurality of other communication apparatuses connected to the communication apparatus;

determining whether the frame is a frame for periodic Low Latency communication; and

making a predetermined notification so as to limit a time length of a transmission frame by a second other communication apparatus different from the first other communication apparatus among the plurality of other communication apparatuses, in a case where it is determined that the frame is the frame for the Low Latency communication,

wherein information corresponding to attributes of the Low Latency communication decided by the first other communication apparatus is set in the frame for the Low Latency communication,

wherein the attributes of the Low Latency communication include a start time of the Low Latency communication, a permissible delay time in the Low Latency communication, and a minimum communication data amount in the Low Latency communication.

7 . A non-transitory computer-readable storage medium that stores a program for causing a computer included in a communication apparatus complying with an IEEE 802.11 series standard to:

receive a frame for requesting a TWT (Target Wake Time) operation from a first other communication apparatus among a plurality of other communication apparatuses connected to the communication apparatus;

determine whether the frame is a frame for periodic Low Latency communication; and

make a predetermined notification so as to limit a time length of a transmission frame by a second other communication apparatus different from the first other communication apparatus among the plurality of other communication apparatuses, in a case where it is determined that the frame is the frame for the Low Latency communication,

wherein information corresponding to attributes of the Low Latency communication decided by the first other communication apparatus is set in the frame for the Low Latency communication,

wherein the attributes of the Low Latency communication include a start time of the Low Latency communication, a permissible delay time in the Low Latency communication, and a minimum communication data amount in the Low Latency communication.
