摘要： Provided is a cable modem control method. The cable modem control method checks upstream parameters which are received by a cable modem termination system to check a status of an upstream channel. The cable modem control method determines whether the upstream channel is good or whether to allow an upstream data transmission of a cable modem on the basis of a result of the check. The cable modem control method suspends the upstream data transmission of the cable modem and performs ranging when the upstream channel is not good as a result of the determination. The cable modem control method postpones bandwidth allocation to a channel of the cable modem and allocates a bandwidth to another usable upstream channel. The cable modem control method returns to a normal status when the ranging is successfully ended.

摘要： An orthogonal frequency division multiple access (OFDMA) communication system. The system has a plurality of cells, divides an entire frequency band into a plurality of subcarrier bands in each cell, and has subchannels that are a set of a preset number of subcarrier bands, respectively. Interference from neighbor cells of the plurality of cells is predicted. A time interval in which interference is absent and a time interval in which the interference is present are classified according to the interference predicted from the neighbor cells. Transmit power is equally distributed and allocated to subchannels capable of being allocated in the time interval in which the interference is absent. Transmit power is adjusted and allocated for the subchannels capable of being allocated such that inference to the neighbor cells does not occur in the time interval in which the interference is present.
