    • Disclosed herein are apparatus, methods and computer program products for transmitting signals in different frequency sub-bands used in a particular cell of a cellular wireless communications system in accordance with a power sequence and for selecting modulation schemes to be used in transmitting the signals in the different frequency sub- bands in dependence on signal transmission power allocated to the sub-bands in the power sequence. In the power sequence, signals to be transmitted in at least one sub- band are allocated a higher signal transmission power level than signals to be transmitted in other sub-bands used in the particular cell of the cellular wireless communication system. The differing signal transmission power levels allocated to the different sub- bands typically results in different SINR for signals transmitted at the higher signal transmission power levels and signal transmitted at the lower signal transmission power levels, hi order to reduce the SINR difference between signals transmitted in the different sub-bands, modulation schemes are selected in dependence on the signal transmission power levels allocated to signals transmitted in the sub-bands.
    • 本文公开了用于根据功率序列在蜂窝无线通信系统的特定小区中使用的不同频率子带中发送信号的装置,方法和计算机程序产品,并且用于选择要在传输信号中使用的信号的调制方案 根据分配给功率序列中的子带的信号传输功率,不同的频率子带。 在功率序列中,要在至少一个子带中发送的信号被分配比在蜂窝无线通信系统的特定小区中使用的其他子带中要发送的信号更高的信号发射功率电平。 分配给不同子带的不同信号传输功率电平通常会导致在较高信号传输功率电平下传输的信号和以较低信号传输功率电平传输的信号的不同的SINR。为了减少传输的信号之间的SINR差异 根据分配给在子带中发送的信号的信号传输功率电平来选择不同的子带调制方案。
