Efficient Co-Existence Method for Dynamic Spectrum Sharing |
| 摘要 |
An apparatus defines a set of resources out of a first number of orthogonal radio resources and controls a transmitting means to simultaneously transmit a respective first radio signal for each resource on all resources of the set. A respective estimated interference is estimated on each of the resources of the set when the respective first radio signals are transmitted simultaneously. A first resource of the set is selected if the estimated interference on the first resource exceeds a first predefined level and, in the set, the first resource is replaced by a second resource of the first number of resources not having been part of the set. Each of the controlling and the estimating, the selecting, and the replacing is performed in order, respectively, for a predefined time. |

1. Apparatus, comprising
set defining means adapted to define a set of resources out of a first plurality of resources, wherein the resources are orthogonal radio resources; first controlling means adapted to control a transmitting means to simultaneously transmit a respective first radio signal for each resource on all resources of the set; interference estimating means adapted to estimate a respective estimated interference on each of the resources of the set when the respective first radio signals are transmitted simultaneously on all resources of the set; first selecting means adapted to select a first resource of the set if the estimated interference on the first resource exceeds a first predefined level; replacing means adapted to replace, in the set, the first resource by a second resource of the first plurality of resources not having been part of the set; first repetition controlling means adapted to control, upon a trigger, the first controlling means, the interference estimating means, the first selecting means, and the replacing means to perform in order each of the controlling and the estimating, the selecting, and the replacing, respectively, for a predefined time. |
