Method for identifying reusable multiplexing resources and telecommunications system

摘要

A method and telecommunications system for identifying uplink multiplexing resources of a multi-beam satellite that are usable in a land-based telecommunications system, e.g., a transmitting station for transmitting radio signals to a receiving station. The transmitting station or the receiving station being a base station having a range defining a coverage area. For a given uplink multiplexing resource, a maximum allowable interference level, with respect to the satellite, for radio-electric signals transmitted from the coverage area is estimated. A potential interference level of the transmitting station is estimated. The transmitting station determines the usability of the given uplink multiplexing resource by comparing the potential interference level with the maximum allowed interference level for the given uplink multiplexing resource.

1. A method for identifying uplink multiplexing resources of a multi-beam satellite that can be used in a terrestrial telecommunications system by a transmitting station to transmit radio-electric signals to a receiving station, comprising the steps of:
estimating a maximum interference level authorized with respect to the satellite for an uplink multiplexing resource for radio-electric signals transmitted from a zone of coverage, wherein the transmitting station or the receiving station is a base station having a range delimiting the zone of coverage in which the transmitting station is situated, and wherein different beams of satellite use different uplink multiplexing resources; estimating a radiation power of the radio-electric signals transmitted by the transmitting station; measuring, by the transmitting station, a real reception level of the radio-electric signals transmitted by the satellite; determining a potential level of interference of the transmitting station as a function of the real reception level measured and of the estimated radiation power of the transmitting station; and determining whether said uplink multiplexing resource is usable by the transmitting station by comparing the potential level of interference of the transmitting station with the maximum interference level authorized for said uplink multiplexing resource.
