Abstract: A method, apparatus and computer program for allocating resources in a communication system. An access node sends a request for shared resources to one or more neighboring access nodes which have a strong interference bond with the access node. The neighboring access nodes send a response identifying the nature of their use of the shared resources. The access node then determines a new allocation of the shared resources based on the responses. This new allocation is then signalled to the neighboring access nodes.

Abstract: It is checked if a first CRE from a first cell is larger than 0; and if a second CRE from a second cell is larger than 0. If both the first and the second CRE are larger than 0, a first modified CRE is set based on the first CRE and a second modified CRE is set based on the second CRE. If the first CRE and/or the second CRE is equal to 0, the first modified CRE is set to the first CRE and the second modified CRE is set to the second CRE. One of the first and second cell is selected for cell selection and/or handover based on a comparison of a sum of a signal strength indicator from the first cell and the first modified CRE and a sum of a signal strength indicator from the second cell and the second modified CRE.
