摘要： A radio base station apparatus used in a radio communication system in which an initiator holds a transmission opportunity (TXOP) period in a frame exchange sequence and a responder responds to the initiator in the frame exchange sequence is disclosed. The apparatus includes a setting device which sets a ratio between a first period necessary for transmitting a first frame from the initiator to the responder and a second period necessary for transmitting a second frame from the responder to the initiator. The apparatus also includes a calculation device which calculates the first period to be used by the initiator and the second period to be used by the responder, on the basis of the transmission opportunity period and of the ratio which is set.

摘要： A communication apparatus includes a receiving device configured to receive one physical frame in which a plurality of MAC frames are aggregated. This physical frame includes one acknowledgement request frame for the plurality of MAC frames. The apparatus includes an acknowledgement frame forming device configured to form an acknowledgement frame representing reception statuses of the plurality of MAC frames in response to the acknowledgement request frame. The apparatus also includes a transmitting device configured to transmit the acknowledgement frame. This acknowledgement frame includes a compressed acknowledgement frame representing an acknowledgement bitmap having a size equal to a maximum number of MSDUs (MAC Service Data Units) when one MPDU (MAC Protocol Data Unit) corresponds to one MSDU.

摘要： A communication apparatus includes a receiving device configured to receive a physical frame in which a plurality of MAC frames, each having a sequence number, are aggregated. A reception buffer which stores MAC frames of the physical frame received by the receiving device. A determination device determines whether or not the first MAC frame in the physical frame received by the receiving device has been successfully received. A reception buffer management device determines, when the first MAC frame has been successfully received, a MAC frame to be forwarded to an upper layer, on the basis of the sequence number of the first MAC frame, and extracts the MAC frame from the reception buffer.

摘要： A generation device generates a frame to be transmitted to a destination communication apparatus. The frame includes a first separation field, a first MAC protocol data unit (MPDU) following the first separation field, a second separation field following the first MPDU, a third separation field following the second separation field, and a third MPDU following the third separation field. The second separation field includes length information set to a value of zero to indicate no second MPDU directly follows the second separation field. The first MPDU includes a first MAC header, a first data field, and a first frame check sequence (FCS). The first FCS is for detecting an error occurred in at least the first data field. The third MPDU includes a third MAC header, a third data field, and a third FCS. The third FCS is for detecting an error occurred in at least the third data field.
