Definitions

Coordinated Multipoint (CoMP) transmission and reception comprises a series of schemes that a user equipment (UE) is served simultaneously by several points to enhance the received signal quality. A point refers to a set of geographically co-located transmit antennas, such as the set of antennas at a cellular base station (BS). Note that different sectors of the same BS site are thought of as different points. In CoMP, the channel state information (CSI) and/or data needs to be shared among neighboring points to coordinate their transmissions in the downlink or jointly process the received signals in the uplink. CoMP can effectively turn otherwise harmful intra-cell or inter-cell interference into useful signals and achieve significant power gain. It is an effective tool to improve the coverage of high data rates, the cell-edge throughput, and also to increase system throughput.

Historical Background

CoMP is a special technique of base...
