METHODS AND NODES FOR COORDINATING UPLINK TRANSMISSIONS IN A WIRELESS COMMUNICATION NETWORK

摘要

Methods and nodes for coordinating uplink transmissions in a victim cell and in an aggressor cell. The uplink transmissions in the aggressor cell potentially cause interference at a victim radio node receiving or measuring uplink signals transmitted in the victim cell. A coordinating node obtains (200) an indication of an uplink pattern of interference-protected resources in frequency and time where uplink transmissions are allowed to be scheduled in the victim cell but not in the aggressor cell. The coordinating node then signals (202) the indication to an aggressor radio node serving the aggressor cell and/or to the victim radio node. When a radio node receives (204) the signaled indication, it uses (206) the uplink pattern for scheduling uplink transmissions in one or both of the victim cell and the aggressor cell, or for configuring a measurement or signal reception. The coordinating node may be the victim radio node (302), or the aggressor radio node (300), or a network node (304) signalling the indication to one or both of the victim radio node and the aggressor radio node.
