摘要： The invention discloses a method and apparatus for supporting increased capacity on a backhaul communications link carrier frequency of a wireless communication system using a repeater station (12-1 to 12-i and 12-12-n-2 to 12-n). Uplink RF carrier signals (20) from a plurality of mobiles units (18-1, 18-2) each having a first modulation scheme, are received at a serving repeater station (12-1 to 12-i). These uplink signals containing traffic and control information are demodulated and then re-modulated by a second modulation scheme having a higher-order modulation than the first modulation scheme. The re-modulated signal containing a plurality of uplink carrier signals within a single RF carrier is then transmitted over an uplink channel of a backhaul communication link (19). Additionally, the invention discloses a method for aggregating data which each of the uplink carrier signals containing traffic and control information are then compressed into a single RF carrier signal which is transmitted over an uplink channel of a backhaul communication link.
