Abstract
A method for a cooperative communication according to a portion of the present specification, may include receiving at least one of information related to a radio access point and information related to a user equipment (UE) receiving a service from the radio access point, from the radio access point. The receiving may be performed by using a User Datagram Protocol (UDP) and a General Packet Radio Service (GPRS) Tunneling Protocol (GTP).
Claims12
A method for coordinated multipoint (CoMP) communication by a first base station, comprising:
- transmitting, to a second base station, a message including a reference signal received power (RSRP) measurement report of a terminal and a channel state information (CSI) report of the terminal, wherein the RSRP measurement report comprises identification of at least one of a serving cell that serves the terminal, on which a RSRP is measured, or a neighbor cell of the serving cell, on which the RSRP is measured;
- and
- receiving, from the second base station, coordination information which is determined based on the RSRP measurement report and the CSI report at the second base station,
- wherein the coordination information includes a resource assignment hypothesis for the CoMP communication and a benefit metric associated with the resource assignment hypothesis, wherein the benefit metric includes a value indicating an expected level of a benefit obtained by adopting the resource assignment hypothesis for the CoMP communication.

A method for coordinated multipoint (CoMP) communication by a second base station, comprising:
- receiving, from a first base station, a message including a reference signal received power (RSRP) measurement report of a terminal and a channel state information (CSI) report of the terminal, wherein the RSRP measurement report comprises identification of at least one of a serving cell that serves the terminal, on which a RSRP is measured, or a neighbor cell of the serving cell, on which the RSRP is measured;
- determining coordination information based on the RSRP measurement report and the CSI report;
- and
- transmitting, to the first base station, the determined coordination information,
- wherein the coordination information includes a resource assignment hypothesis for the CoMP communication and a benefit metric associated with the resource assignment hypothesis, wherein the benefit metric includes a value indicating an expected level of a benefit obtained by adopting the resource assignment hypothesis for the CoMP communication.
