Abstract
The present disclosure relates to a method and an access node 112 for reducing interference The access node 112 communicates with a user equipment 111 over a wireless access interface a i in a wireless communication network 100 The method comprises the actions of obtaining (S2) timing information indicative of one or more periods when a relay node 116 communicates with a donor node 112 over a wireless backhaul interface b h i, and identifying (S1) that the user equipment 111 is receiving a signal from the relay node 116 communicating with the donor node 112 over the backhaul interface b h I that is stronger than a predetermined threshold, and in response to identifying that the user equipment 111 is receiving a signal from the relay node 116 that is stronger than a predetermined threshold, prioritising (S3) communication between the access node 112 and the identified user equipment 111 via the access interface a i during the periods when the relay node 116 communicates with the donor node 112 over the backhaul interface b h i.
