Enhanced receiver adaptation based on relation between signals from aggressor and victim cells

A method in a node for assisting a first radio node in adapting a receiver type in the first radio node for receiving signals from a second radio node, the first radio node comprising a receiver that is configured to selectively operate according to at least two receiver types, and the node, the first radio node, and the second radio node being comprised in a wireless communications network, the method comprising:

• determining assistance data, the assistance data being for assisting the first radio node in adapting the receiver in the first radio node to selectively operate according to one of the at least two receiver types, for receiving first signals from the second radio node, wherein the adapting selects between the at least two receiver types based on a determination made from the assistance data, wherein the assistance data is related to activity of the first signals and second signals received from at least one third radio node, wherein the first signals comprise signals received from a first cell associated with the second radio node, wherein the second signals comprise signals received from a second cell associated with the at least one third radio node, wherein the at least one third radio node is comprised in the wireless communications network, and wherein the second signals from the at least one third radio node cause interference on the first signals;
• and
• signalling the assistance data to the first radio node,
• wherein adapting the receiver comprises configuring the receiver of the first radio node to operate according to the one of the at least two receiver types, and
• wherein the at least two receiver types are different from each other with respect to operations performed by the receiver to mitigate interference.

A first radio node for adapting a receiver type in the first radio node, the first radio node comprising a receiver that is configured to selectively operate according to at least a first receiver type and a second receiver type, the two receiver types being different, and the first radio node being adapted to be comprised in a wireless communications network, the wireless communications network further comprising a second radio node and at least one third radio node, and the first radio node comprising:

• an adapting circuit configured to adapt the receiver of the receiver of the first radio node to selectively operate according to one of the first receiver type and the second receiver type, for receiving first signals from the second radio node, wherein the adapting circuit is configured to select between the first receiver type and the second receiver type based on a determination made from a relation between an activity of the first signals and second signals received from the at least one third radio node, wherein the first signals comprise signals received from a first cell associated with the second radio node, wherein the second signals comprise signals received from a second cell associated with the at least one third radio node, and wherein the second signals from the at least one third radio node cause interference on the first signals,
• wherein adapting the receiver comprises configuring the receiver of the first radio node to operate according to the one of the first receiver type or the second receiver type, and
• wherein the first receiver type and second receiver type are different from each other with respect to operations performed by the receiver to mitigate interference.
