UPLINK INTERFERENCE RESOLUTION IN A WIRELESS COMMUNICATION SYSTEM

摘要

An access node is provided in a wireless communication network for conducting interference resolution of a received signal, the access node comprising a transceiver module, a backhaul module, and a memory. The access node further comprises a processor coupled to the transceiver module, the backhaul module and the memory and configured to identify a neighboring access node in the wireless communication network, to exchange, via the backhaul module, communication parameters with the neighboring access node, to receive, via the transceiver module, a signal comprising a transmission from a first user equipment and an interfering transmission from a second user equipment, the signal being received over a plurality of uplink resources, to receive, via the backhaul module, resource information from the neighboring access node, the resource information corresponding to the plurality of uplink resources, and to apply the resource information for interference resolution of the received signal.
