Abstract:
1. A method in a radio network node for redistributing resources between at least a first and a second communication device, the method comprising: obtaining a first estimate of a first signal quality for the first communication device and a second estimate of a second signal quality for the second communication device; determining a first required signal quality for the first communication device and a second required signal quality for the second communication device; and in response to the first required signal quality being less than the first estimate and the second required signal quality being greater than the second estimate, allocating resources to the first and second communication devices such that the first signal quality decreases and such that the second signal quality increases to redistribute resources between the first and second communication devices, wherein the allocation of resources further comprises allocating the resources such that the first signal quality becomes above or at the first required signal quality, wherein the first and second required signal quality is determined based on a size of a common data buffer associated to the first and second communication devices, wherein the first and second required signal quality is great enough to allow the first and second communication device to empty the common data buffer in one allocation, or the first required signal quality is great enough to allow the first communication device to empty a first data buffer, associated to the first communication device, in one allocation, and the second required signal quality is great enough to allow the second communication device to empty a second data buffer, associated to the second communication device, in one allocation.
