A method of configuring a sub-slot having a layer-modulated multi-user packet (MUP) is disclosed. More specifically, the method comprises modulating symbols associated with a first layer by using non-layered modulation scheme, and modulating symbols associated with a second layer and a third layer using a different layered-modulation scheme. Here, the symbols associated with the second layer and the third layer are multiplexed by any one of an orthogonal frequency division multiplexing, a code division multiplexing, a multi-carrier code division multiplexing, or a time division multiplexing.

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.
