Abstract:
A base station node (BS) of a heterogeneous radio access network comprises a terminal locator (34) and a scheduler (36). The terminal locator (34) obtains an indication of location of a wireless terminal (30) in a cell served by the base station (BS), e.g., whether the wireless terminal (30) is in a center region (M) or an edge region (E) for the cell served by the base station node (BS). The scheduler (36) uses the indication of location to assign to the wireless terminal (30) a frequency of a frequency bandwidth usable by the heterogeneous radio access network. The scheduler (36) assigns a frequency from a partitioned portion of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in an edge region of a micro cell. The scheduler (36) also assigns a frequency of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in a center portion of the micro cell.
