Abstract

A communication apparatus includes a physical frame generating device configured to generate a single physical frame which includes a plurality of media access control frames having different destinations and in which frames, of the media access control frames, which have the same destination are consecutively arranged, and a transmitting device configured to transmit the physical frame generated by the physical frame generating device.

Claims (9)

1. A communication apparatus comprising:

a generation device configured to generate a frame,

the frame comprising

a first separation field, the first separation field including at least a first MAC protocol data unit (MPDU) length field and a first cyclic redundancy check (CRC) field, the first MPDU length field including first length information of a first MPDU, the first CRC field being for protecting at least the first length information,

the first MPDU following the first separation field,

a second separation field following the first MPDU, the second separation field including at least a second MPDU length field and a second CRC field, the second MPDU length field including second length information set to a value of zero to indicate no second MPDU directly follows the second separation field, the second CRC field being for protecting at least the second length information,

a third separation field following the second separation field, the third separation field including at least a third MPDU length field and a third CRC field, the third MPDU length field including third length information of a third MPDU, the third CRC field being for protecting at least the third length information,

the third MPDU following the third separation field,

wherein the frame is to be transmitted to a destination communication apparatus.
