1. A communication apparatus comprising:
- circuitry configured toinitiate a generation of a plurality of frames to be transmitted by multiplexing,initiate an application of a padding on at least a part of the generated plurality of frames to adjust frame lengths, andinitiate a multiplexing of the plurality of frames after the frame lengths have been adjusted,wherein information indicating one pattern of a plurality of predetermined padding position patterns is provided in a preamble or a header part of the frames,wherein the plurality of predetermined padding position patterns include a first pattern and a second pattern, the first pattern corresponding to padding on an end portion inserted after data of a data section of each frame, and the second pattern corresponding to padding on one or more intermediate parts of the data section inserted within the data of the data section of each frame, wherein the one or more intermediate parts do not include a head or end of the data section, andwherein the one pattern is selected from among the plurality of predetermined padding position patterns.

Abstract
Frames in a variable length frame format which are addressed to a plurality of users are multiplexed and preferably transmitted. Data frames having different lengths are multiplexed on a same time through space division multiple access, but since the multiplexed frames are transmitted while eventually having a same length, when the multiplexed data frames from the access point STA0 are received in the respective communication stations STA1 to STA3 in FIG. 4 or when data simultaneously transmitted from the respective communication stations STA1 to STA3 are received in the access point STA0 in FIG. 5, it is possible to eliminate an operation instability of AGC.

21. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
-
generating a plurality of frames to be transmitted by multiplexing; applying a padding on at least a part of the generated plurality of frames to adjust frame lengths; and multiplexing the plurality of frames after the frame lengths have been adjusted, wherein information indicating one pattern of a plurality of predetermined padding position patterns is provided in a preamble or a header part of the frames, wherein the plurality of predetermined padding position patterns include a first pattern and a second pattern, the first pattern corresponding to padding on an end portion inserted after data of a data section of each frame, and the second pattern corresponding to padding on one or more intermediate parts of the data section inserted within the data of the data section of each frame, wherein the one or more intermediate parts do not include a head or end of the data section, and wherein the one pattern is selected from among the plurality of predetermined padding position patterns. - View Dependent Claims (22, 23)
