Nonterrestrial cellular mobile telecommunication system
First Claim
1. A cellular mobile telecommunication system for providing radio communication with non-terrestrial mobile subscriber stations using radio frequencies allocated for ground-based mobile telecommunication stations, comprising:
- at least one radio transmitter for generating at least one telecommunication cell, each telecommunication cell having three-dimensional extent, arranged in at least three dimensions, with communication signals generated by said at least one transmitter being at radio frequencies allocated for ground-based mobile subscriber stations, incapable of reception by said ground-based mobile subscriber stations;
at radio frequencies allocated for ground-based mobile subscriber stations, incapable of reception by said ground-based mobile subscriber stations;
at least one radio receiver for receiving communication signals generated by said non-terrestrial mobile subscriber stations extant in said at least one telecommunication cell with communication signals generated by said non-terrestrial mobile subscriber stations being at a wavelength allocated for ground-based mobile telecommunication stations and incapable of reception by said ground-based mobile subscriber stations.

Abstract
The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.
