GROUP-BASED RESOURCE ELEMENT MAPPING FOR RADIO TRANSMISSION OF DATA

摘要

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.
