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.
摘要:
A wireless communication system basestation making use of a wideband, multichannel digital transceiver having incorporated therein a time division multiple-access (TDM) bus for providing digital samples of a plurality of wireless communication channels, wherein the time slot duration and frame rate of the TDM bus may be reconfigured. The invention allows various air interface standards, even those having different channel bandwidths, to be serviced by the same basestation, without having to install additional or different equipment, and by automatically redistributing signal processing resources, eliminating the need to reconfigure the basestation when different types of wireless signalling must be accomodated.
