Abstract
A method for implementing coordinated multi-point transmission and reception in a multi-carrier network system including a first serving network node and a second cooperating network node is disclosed. The method includes the steps of configuring a first transmission channel. The first transmission channel is established on the first serving network node. The method includes configuring a second transmission channel. The second transmission channel is established on the second cooperating node. The method includes transmitting control information using the first transmission channel. The control information allocates a resource on the second transmission channel and the second transmission channel is not established on the first serving network node.
