Group-based resource element mapping for radio transmission of data

用于数据无线电传输的基于组的资源单元映射

Abstract

For transmitting data over a radio interface using subframes with a plurality of resource elements organized in a time-frequency grid, at least two groups of resource elements are determined from the resource elements of one of the subframes. Each group covers multiple consecutive resource elements in the time domain and is distinct from the at least one other group in the frequency domain. Data symbols of a sequence are consecutively mapped to the resource elements of one of the groups. If a data symbol is mapped to each resource element of the group, the next data symbols of the sequence are consecutively mapped to the resource elements of a further one of the groups.
为了使用具有被组织为时频网格的多个资源单元的子帧通过无线电接口发送数据,根据子帧之一的资源单元确定至少两组资源单元。每组资源单元在时域中覆盖多个连续资源单元,并且在频域中与至少一个其它组不同。将所述序列中的数据符号连续映射到所述组之一的资源单元。如果数据符号被映射到所述组的每个资源单元,则将该序列中的后续数据符号连续映射到所述组中的另一组的资源单元。
