    摘要: This invention is a manner of Coordinated Multi-Point (CoMP) transmission between with plural base stations and at least one user equipment. The user equipment measures channel state information of plural base stations using plural CSI-RS resources based on the nodes to which that user equipment can communicate. Generally the identity of these nodes is signaled to the user equipment by one of the base stations. The user equipment calculates a channel state information for each of the base stations and transmits a corresponding channel state indicator response. A higher-layer signaling from at least one base station to the user equipment configures the CSI-RS sequence for each of plural CSI-RS resources. One base station determines communications parameters for communication with the user equipment and plural base stations and signals the user equipment. The user equipment establishes communication with the plural base stations via the determined communication parameters.

    摘要: A method for setting a periodicity and an offset in rank indicator (RI) reporting in a user equipment in a wireless communication system receives a radio resource control (RRC) signal from a base station, decodes a RI periodicity and offset configuration index, sets the periodicity and offset in accordance with said decoded periodicity and offset configuration index and reports a RI according to the set periodicity and offset. The periodicity is an integer and reporting a RI reports with equal the product of the periodicity and a period of reporting of the channel quality indicator (CQI) and the precoding matrix indicator (PMI).
