FIELD: physics; communications. ^ SUBSTANCE: invention relates to communication engineering. In the communication system, a base station generates first information which comprises information for allocating downlink resources, required for supporting a first mode supported by the base station, second information is generated which comprises length of the first information, and the first information and second information are transmitted. A mobile station notifies the base station on a second mode supported by the mobile station, receives, after notification, first information and second information from the base station and transmits as much information for allocating downlink resources as constituted by the length which corresponds to length information, without decoding, if the first mode is different from the second mode. ^ EFFECT: providing users with high-speed services having different service quality. ^ 16 cl, 3 dwg, 19 tbl |
