Abstract: A method is provided for scheduling downlink and uplink data bursts in a frame for communication between a node station and a plurality of access terminals including half-duplex terminals, comprising the steps of allocating, in a current frame having a downlink and an uplink portion, a Tx burst in the uplink portion of the frame for each access terminal, the Tx burst of each access terminal starting at a time in the uplink portion which is greater than or equal to the start time in the downlink portion of corresponding Rx data incremented by the duration of said Rx data.

Abstract: The present invention describes a network planning mechanism for the optimisation of system quality associated with frequency reuse for a mobile network infrastructure and business access applications, by using an intelligent combination of microwave point-to-point and point-to-multipoint links in Broadband Wireless Access Systems or LMDS, for example. In an embodiment of the invention, Radio Base Stations (RBSs) sites can be connected to the Switch site by a combination of fibre optics, leased lines, or preferably microwave radio links. The embodiment enables traffic from several end sites to be concentrated at selected hub sites (hub site 1-4). The system is optimised by minimizing the quality degradation that can be experienced due to excessive interference inside a certain portion of the point-to-multipoint covered sector by means of the combined point-to-multipoint and point-to point solutions.

Abstract: The invention refers to a point to multi-point hybrid frequency band system architecture for terrestrial wireless broadband access applications, operating on bands having high terrestrial frequency (above 20 GHz) in downlink and on bands having low terrestrial bands (below 11 GHz) in uplink.
