Abstract

Even when the lengths of data items to be transmitted to users are not the same, the frames multiplexed at the same time finally have the same frame length and are transmitted.
Even when the lengths of frames for the users are not the same at the time when a transmission request is received from a higher layer, a communication apparatus reconfigures at least two of the frames having short lengths into a frame having a long length through Aggregation so that the frames finally have the same frame length and transmits the frames at the same time in a multiplexed manner. On the transmitter side, the transmission power used per destination communication station can be increased due to a decrease in the total number of multiplexed frames. On the receiver side, an unstable AGC operation can be prevented.

First claim

The invention claimed is:

1. An electronic device comprising:
circuitry configured to
obtain a plurality of MAC frames to be transmitted in a multiplexed signal via a plurality of antennas;
generate a plurality of integrated frames, each integrated frame being generated by integrating at least two frames of the obtained plurality of MAC frames;
generate a plurality of PHY data units, each PHY data unit having a different length and being generated based on each integrated fra…
