Abstract

The present invention relates to a node and a method thereof for a mobile telecommunication network connectable to a controlling node and wirelessly connectable to mobile terminals. The node is adapted to have an uplink connection to a mobile terminal, wherein the mobile terminal is adapted to have a second uplink connection to at least a second node such that data transmitted from the mobile terminal may be received at the node and at the at least the second node. The node comprises means for estimating whether data transmitted from the mobile terminal received at the at least the second node is received stronger than the data received at said node and means for discarding data received from the mobile terminal if it is estimated that the data is received stronger at the at least the second node than the data received at said node.

Claims (13)

1. A method implemented by a node in a mobile telecommunication network, said node connectable to a controlling node and wirelessly connectable to mobile terminals, the node adapted to have an uplink connection to a mobile terminal, wherein the mobile terminal is adapted to have a second uplink connection to at least a second node such that data transmitted from the mobile terminal may be received at the node and at the at least the second node, said method comprising the steps of:

estimating if the mobile terminal is power controlled by said node, and

discarding the data received from the mobile terminal if the mobile terminal is estimated to not be power controlled by said node.

2. The method according to claim 1 , further comprising:

determining if the mobile terminal is power limited; and

forwarding data to the controlling node if it is determined the mobile terminal is not power limited or if the mobile terminal is estimated to be power controlled by said node.

3. The method according to claim 1 , further comprising:

determining if the mobile terminal is in short handover with the at least a second node; and

forwarding data to the controlling node if it is determined the mobile terminal is not in short handover with the at least a second node or if the mobile terminal is estimated to be power controlled by said node.

4. The method according to claim 1 , further comprising:

determining if the mobile terminal is in short handover with the at least a second node;

determining if the mobile terminal is power limited; and

forwarding data to the controlling node if it is determined the mobile terminal is not in short handover with the at least a second node, or if it is determined the mobile terminal is not power limited, or if the mobile terminal is estimated to be power controlled by said node.
