Communication apparatus and control method of communication apparatus

A communication apparatus compliant with the IEEE802.11 standard series, comprising:

• a communication unit configured to transmit and receive radio signals for wireless communication,
• at least one processor, and
• at least one memory coupled to the at least one processor and having instructions stored thereon, and when executed by the at least one processor, causing the communication apparatus to:
• receive a first plurality of data frames transmitted using a first link and a second plurality of data frames transmitted using a second link from a communication partner apparatus;
• receive, from the communication partner apparatus, first sequence information about sequence numbers of the first plurality of data frames transmitted on the first links and second sequence information about sequence numbers of the second plurality of data frames transmitted on the second link;
• and
• transmit a first acknowledgement (Ack) frame to the first plurality of received data frames and a second Ack frame to the second plurality of received data frames,
• wherein the first sequence information includes identification information that identifies at least one data frame group included in the first plurality of data frames transmitted on the first link, and the second sequence information includes identification information that identifies at least one data frame group included in the second plurality of data frames transmitted on the second link,
• each of the at least one data frame group comprises a series of data frames and the series of data frames has consecutive sequence numbers,
• the identification information includes, for one Traffic Identifier, a plurality of combinations of start sequence number information and end sequence number information for each of the series of data frames within each of the first and second pluralities of data frames, and
• each of the first and second Ack frame includes a reception result with respect to a data frame included in each of the at least one data frame group transmitted on each of the first and second link that is identified by the identification information.

A method of controlling a communication apparatus compliant with the IEEE802.11 standard series, comprising:

• transmitting a first plurality of data frames on a first link and a second plurality of data frames on a second link to a communication partner apparatus;
• transmitting, to the communication partner apparatus, a first request frame that requests a first acknowledgement (Ack) frame to the first plurality of transmitted data frames and a second request frame that requests a second Ack frame to the second plurality of transmitted data frames;
• and
• receiving the first and second Ack frames from the communication partner apparatus in response to transmitting the first and second request frames,
• wherein the first request frame includes first sequence information about sequence numbers of the first plurality of data frames transmitted on the first link and the second request frame includes second sequence information about sequence numbers of the second plurality of data frames transmitted on the second link,
• the first sequence information includes identification information that identifies at least one data frame group included in the first plurality of data frames transmitted on the first link, and the second sequence information includes identification information that identifies at least one data frame group included in the second plurality of data frames transmitted on the second link,
• each of the at least one data frame group comprises a series of data frames and the series of data frames has consecutive sequence numbers, and
• the identification information includes, for one Traffic Identifier, a plurality of combinations of start sequence number information and end sequence number information for each of the series of data frames within each of the first and second pluralities of data frames.
