Claim of US Patent No. 10,462,836

1. A method for communicating, by a network, with a user equipment (UE) in a wireless communication system, the method comprising:collaborating a plurality of base stations;
configuring the collaborated base stations as a first master base station;
configuring each of the plurality of base stations as a secondary base station;
configuring a first set of resources for the first master base station;
communicating with the UE based on an identifier (ID) of the first master base station, in the configured first set of resources for the first master base station, via the collaborated base stations configured as the first master base station; and
communicating with the UE based on an ID of the secondary base station, in a second set of resources different from the first set of resources, via the each of the plurality of base stations configured as the secondary base station,
wherein the same set of transmission points (TPs) and a pseudo quasi collocated indicator (PQI) table are maintained regardless of a mobility of the UE by using a tight coordination among the TPs and by allocating a UE-dedicated set of TPs and associated resources,
wherein a UE-dedicated resource based transparent TP update procedure is performed by using a discovery signal transmitted periodically from a TP,
wherein a scrambling ID of the discovery signal transmitted periodically from the TP is different from a scrambling ID of feedback channel status information¬óreference signal (CSI-RS), and
wherein two different types of resources are used in order to avoid a collision between the discovery signal transmitted periodically from the TP and the feedback CSI-RS.
