NON-TERRESTRIAL CELLULAR MOBILE TELECOMMUNICATION STATION |
摘要 |
The non-terrestrial cellular mobile telecommunication station uses a number of non-interference techniques to extend the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to the non-terrestrial realm. For example, the polarization of the signals produced by the antenna elements of the non-terrestrial cellular mobile telecommunication station is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas to thereby minimize the possibiliy of interference with the 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. The transmit power of the non-terrestrial cellular mobile telecommunication station is also tightly controlled and of a magnitude to be rejected by the ground-based mobile subscriber stations and cell site transmitter-receiver pairs.
