SIGNALLING ARRANGEMENT FOR INTER-SITE CARRIER AGGREGATION HAVING ONLY SINGLE COMPONENT CARRIER AVAILABLE IN UPLINK DIRECTION

摘要

An apparatus is described which is connectable to a first network node by a first downlink component carrier and to at least a second network node by a at least second downlink component carrier, wherein the apparatus provides a single uplink connection. The uplink connection is shared among a first uplink component carrier to the first network node and at least a second uplink component carrier to the at least second network node. Sharing of the uplink connection may be performed in a time divisional multiplexed manner. Further- more, a corresponding method is described.
