Cell configuration for self-organized networks with flexible spectrum usage

摘要

The present invention relates to methods and apparatuses for controlling cell configuration in a cellular network, wherein a cell identity and a local cell spectrum resource entity or profile are assigned to an access device in response to a result of sensing a local radio environment at said access device to detect possible neighbor cells. The assigned local cell spectrum resource entity or profile is used to allocate cell spectrum resource from a shared multi-operator spectrum to said access device.

1. A method of controlling cell configuration in a cellular network, said method comprising:
assigning a cell identity and a local cell spectrum resource entity or profile to an access device in response to determining a local radio environment to detect possible neighbor cells; wherein said assigned local cell spectrum resource entity or profile includes a semi-static part that is exclusive to the access device and a dynamic shareable part to enable allocation of cell spectrum resource to said access device depending on the local radio environment operable to establish implicit coordination between local cells of the cellular network based on the local radio environment, and to allocate cell spectrum resource from a shared multi-operator spectrum to said access device based on both the semi-static part and the dynamic shareable part, wherein the local cell spectrum resource entity or profile is selected from a limited set of predefined basic cell spectrum resource entities or profiles provided for cell configuration of the cellular network, and the semi-static part accommodates semi-static instances of common and control channels specific to the access point and the dynamic shareable part is adapted to allocate the available system bandwidth or spectrum resources seen by the local access point.
