Adaptive wireless link layer using a point-to-multipoint channel

摘要

The invention provides an adaptive wireless link layer, wherein a base station controller (120) determines sets of physical and MAC parameters that consider optimal for each set of customer premises equipment (130). The base station controller instructs each of the customer premises equipments to conduct further communications using those new parameters. A frame descriptor package (250) pre-announces the new set of parameters to each customer premises equipment (130), thereby allowing them to configure themselves to the new set of parameters. The frame descriptor package (250) is always the first packet in the TDMA frame and it has always a fixed size. The use of point-to-multipoint wireless channel provides services over a link whose parameters are continuously adapting to current conditions, on a pre-user basis.
