    • An apparatus is provided, including an observing function configured to observe an indication about the coverage status of a user equipment; a deciding function configured to decide, based on the indication, to switch into a coverage extension mode; a providing function configured to provide a scaling number in dependence of the coverage extension mode; an allocating function configured to allocate, for data to be transmitted to a user equipment, a first modulation and coding scheme, a first modulation order, a first size of a transport block, and a first number of resource blocks per transport block according to an orthogonal frequency division multiplexing technology, a reducing function configured to reduce a first size per resource block, being the quotient of the first size of the transport block and the first number of resource blocks per transport block, based on the scaling number, thus obtaining a second size per resource block, being the quotient of a second size of the transport block and a second number of resource blocks per transport block; and a scheduling function configured to schedule, for the data, the second size of the transport block and the second number of resource blocks per transport block.
    • 提供了一种装置,包括:观察功能,用于观察关于用户设备的覆盖状态的指示; 决定功能,被配置为基于所述指示来决定切换到覆盖扩展模式; 提供功能,被配置为根据覆盖扩展模式提供缩放编号; 分配功能,被配置为根据用户设备向用户设备发送第一调制和编码方案,第一调制顺序,传输块的第一大小和每个传输块的第一数量的资源块, 正交频分复用技术,基于缩放数,减少功能,被配置为减少每个资源块的第一大小,作为传输块的第一大小的商和每个传输块的第一数量的资源块,从而获得 每个资源块的第二大小,是传输块的第二大小的商和每个传输块的第二数量的资源块; 以及调度功能,被配置为针对所述数据调度所述传输块的所述第二大小和每个传输块的所述第二数量的资源块。
