Adaptive subchannel and bit allocation method using partial channel information feedback in an orthogonal frequency division multiple access communication system
摘要：
An adaptive subchannel and bit allocation method in a wireless communication system. A mobile station analyzes channel quality information of a subchannel at a predetermined period and determines a feedback band index with a maximum decision criterion. The mobile station feeds back the determined feedback band index with the maximum decision criterion to a base station. The base station generates band allocation information using the feedback information from the mobile station, and transmits the band allocation information to the mobile station. The mobile station transmits AMC information using the band allocation information received from the base station. The base station estimates a channel using the AMC information transmitted from the mobile station and allocates bits to the allocated band according to the channel estimation result.

一种无线通信系统中的自适应子信道和比特分配方法。 移动台以预定周期分析子信道的信道质量信息，并以最大决策准则确定反馈频带索引。 移动台将确定的具有最大决策准则的反馈频带索引反馈给基站。 基站使用来自移动台的反馈信息生成频带分配信息，并将该频带分配信息发送到移动台。 移动台使用从基站接收到的频带分配信息来发送AMC信息。 基站使用从移动站发送的AMC信息来估计信道，并根据信道估计结果向所分配的频带分配比特。
