TRANSMISSION POINT, CHANNEL STATUS INFORMATION REFERENCE SIGNAL SIGNALING METHOD OF TRANSMISSION POINT, USER EQUIPMENT, AND CHANNEL STATUS INFORMATION REPORTING METHOD OF USER EQUIPMENT

摘要

PURPOSE: transmitting terminal, channel state information reference signals configuration signal method transmit terminal, and terminal and reporting source of channel state information terminal report channel status information use CSI-RS patterns. ;CONSTITUTION: CSI-RS configuration information, including an information about CSI-RS transmission frequency and offset is arranged in large area transmission terminal, and the related information of the quantity of antenna port, information is about CSI-RS patterns (S910). Big area transmissions terminal sends CSI-RS configuration information and passes through optical fiber (S920) to RRH. The configuration information of CSI-RS is sent to terminal, passes through top signaling, such as RRC (S930). Each terminal station sends CSI-RS, and which is designated to terminal (S940). Terminal estimates channel state information (S950). Terminal is sending estimated channel state information (S960). ;The 2013 of copyright KIPO submissions;[Reference numerals] (510) terminal; (520) Broad area transmission end; (S910) CSI-RS configuration information is set; (S920) CSI-RS configuration information is sent to send from RRH; (S930) configuration information of CSI-RS is sent; (S940) CSI-RS is sent; (S950) estimating channel status information; (S960) channel state information is sent
