Access node controller, an apparatus for an access node, an access node for a mobile communication system, a mobile communication system, a method and a computer program for an access node

An access node controller for determining one or more transmission parameters of a first access node in a mobile communication system, the access node controller comprising:

• one or more interfaces configured to obtain priority area information of a second access node in the mobile communication system, the second access node having priority access in a priority area compared to the first access node;
• and
• a control module configured to control the one or more interfaces and configured to
• determine the one or more transmission parameters of the first access node based on the priority area information of the second access node and based on an access condition at a priority area boundary;
• and
• determine whether the first access node is located in
• an exclusion zone outside the priority area of the second access node, in which transmission of the first access node is suspended,
• a transitional zone outside the priority area of the second access node and outside the exclusion zone, in which transmission of the first access node is restricted, and
• an open zone outside the priority area of the second access node, outside the exclusion zone and outside the transitional zone, in which transmission of the first access node is unrestricted.

A method for determining one or more transmission parameters for a first access node of a mobile communication system, the method comprising:

• obtaining priority area information of a second access node in the mobile communication system, the second access node having priority access in a priority area compared to the first access node;
• determining the one or more transmission parameters of the first access node based on the priority area information of the second access node and based on an access condition at a priority area boundary;
• estimating an interference level at the priority area boundary of the second access node based on a distance between the first access node and the second access node or between the first access node and the priority area boundary of the second access node;
• and
• determining an estimated interference level at the priority area boundary of the second access node based on an estimated interference contribution of the first access node at the priority area boundary, wherein the estimated interference contribution is based on the one or more transmission parameters.

A non-transitory machine readable medium including code, when executed, to cause a machine to perform a method for determining one or more transmission parameters for a first access node of a mobile communication system, the method comprising:

• obtaining priority area information of a second access node in the mobile communication system, the second access node having priority access in a priority area compared to the first access node;
• determining the one or more transmission parameters of the first access node based on the priority area information of the second access node and based on an access condition at a priority area boundary;
• estimating an interference level at the priority area boundary of the second access node based on a distance between the first access node and the second access node or between the first access node and the priority area boundary of the second access node;
• and
• determining an estimated interference level at the priority area boundary of the second access node based on an estimated interference contribution of the first access node at the priority area boundary, wherein the estimated interference contribution is based on the one or more transmission parameters.
