System and method for managing safety channel in an orthogonal frequency division multiple access communication system |
摘要 |
Disclosed is a method for allocating a safety channel in a wireless communication system which divides a full frequency band into a plurality of subcarrier bands and includes subchannels, each of which is a set of a predetermined number of subbands, each of which is a set of a predetermined number of contiguous subcarriers, where the subchannels include a safety subchannel allocated to particular subscriber stations (SSs), which is unused in a neighbor base station. The method comprises the steps of: transmitting, by the SS, its channel quality information to the base station (BS) when a channel quality of a subchannel allocated to the SS is less than to predetermined reference channel quality; and allocating a safety subchannel to the SS, by the BS upon receiving the channel quality information indicating that the channel quality of the subchannel is less than to the reference channel quality.
