    • Apparatus and methods are provided for decoding DL PHY channels in a narrow band wireless system. In one novel aspect, the UE performs a cell search and determines a first location of a resource block carrying system signals, obtains a second location of a second resource block based on the first resource block, wherein the second resource block includes a format indicator, determines a DL transmission format based on the format indicator, and receives and decodes a first DL physical channel based on the DL transmission format. In one embodiment, the UE operates in either a standalone mode, an in-band mode, or a guard-band mode. The DL transmission format comprises an offset index from a middle/central frequency of the first resource block in the in-band mode or the guard-band mode. In another embodiment, the UE further decodes a second DL physical channel carrying the format indicator.
    • 提供了用于对窄带无线系统中的DL PHY信道进行解码的装置和方法。 在一个新颖的方面,UE执行小区搜索并确定承载系统信号的资源块的第一位置,基于第一资源块获得第二资源块的第二位置,其中第二资源块包括格式指示符, 基于格式指示符确定DL传输格式,并且基于DL传输格式接收并解码第一DL物理信道。 在一个实施例中,UE以独立模式,带内模式或保护带模式操作。 DL传输格式包括来自带内模式或保护带模式的第一资源块的中间/中心频率的偏移索引。 在另一个实施例中,UE还对携带格式指示符的第二DL物理信道进行解码。
