<p>A given allocated contiguous frequency spectrum (for uplink or downlink) is shared by a wireless cellular communications system between a wideband communications portion and a narrowband communications portion. The wideband portion utilizes at least one wideband carrier, and the narrowband portion utilizes a plurality of narrowband carriers. When implemented, the narrowband portion is assigned to both higher power transmission macro-cells and lower power transmission micro- or pico-cells. In this assignment, the plurality of narrowband carriers are assigned to the first and second type cells in a manner where the narrowband carriers located adjacent in the allocated frequency spectrum to the wideband carrier are reserved for assignment only to the lower transmission cells.</p> |
