Claim Text:
1. A method in a base station, which is serving a user equipment, for determining whether a handover of the user equipment is to be made to a relay node, wherein the base station and the relay node are configured for wireless communication with each other over a backhaul link in half-duplex communication mode, the method comprising: obtaining an estimation of data-rate performance over the backhaul link; obtaining an estimation of data-rate performance over a first radio link between the base station and the user equipment; obtaining an estimation of data-rate performance over a second radio link between the relay node and the user equipment; and determining to hand over the user equipment to the relay node, based on end-to-end data rate performance including the obtained estimation of the data-rate performance over the half-duplex backhaul link between the base station and the relay node and the estimations of data-rate performance over the first and second radio links with the user equipment; wherein the base station avoids Ping-Pong effects related to the handover of the user equipment to the relay node by:
