Abstract
Disclosed is a method for performing a handoff in a CoMP cluster. A user equipment measures a signal to interference-plus-noise ratio (SINR) value of each of the CoMP sets constituted by the combination of a plurality of base stations in one CoMP cluster. Then, the user equipment transmits the SINR value of each of the CoMP sets to a serving base station through a pilot strength measurement message (PSMM). Subsequently, the user equipment receives, from the serving base station, a message which instructs a handoff determined through the transmitted signal to interference-plus-noise ratio (SINR) values.

A method of performing handoff between coordinate multipoint (CoMP) sets at a user equipment (UE), in a CoMP cluster including a plurality of base stations (BSs), the method comprising:
- measuring a signal to interference plus noise ratio (SINR) value of each of the CoMP sets constituted by the combination of a plurality of base stations within the CoMP cluster;
- transmitting the SINR value of each of the CoMP sets to a first base station, which is a serving base station, through a pilot strength measurement message (PSMM);
- and
- receiving, from the first base station, a message which instructs handoff based on the transmitted SINR value.
A method of supporting handoff between coordinate multipoint (CoMP) sets at a base station control system in a CoMP cluster including a plurality of base stations, the method comprising:
- receiving, from the user equipment (UE), a signal to interference plus noise ratio (SINR) value of each of the CoMP sets constituted by the combination of the plurality of base stations within the CoMP cluster;
- and
- determining a CoMP active point set based on a resource allocation state of each of the CoMP sets and the SINR value of each of the CoMP sets.
