Concerning the system which uses adaptation modulation coded technology control of the joint authorization which is optimized

摘要

Manner in order to control the authorization of the joint in the radio communication system with base station and the subscriber device is proposed. In the particular system, as for modulation coding system of uplink and down link, with time it is possible to be changed. Particular manner, the step which receives the demand for joint and, the available bandwidth which presently corresponds to AMC mode when it is larger than authorization bandwidth of joint, authorizes joint, the step which updates available bandwidth and, includes. Furthermore, you evaluate manner, cyclically whether presently alteration authorization bandwidth concerning multiple active joints. This in that case to be, in order to recognize alteration and when there is no sufficient bandwidth, manner to halt the authorization of new joint, among multiple active joints to halt one active joint at least at one time, particular alteration the AMC mode of one active joint at least. On the one hand, it is possible presently alteration authorization bandwidth, when there is a sufficient bandwidth in order at the same time to recognize alteration, manner concerning multiple active joints presently updates authorization bandwidth, updates available bandwidth.
