Method and system for CSI-RS resource allocation in LTE-ADVANCE system

摘要

The channel status information access signal (CSI RS) the manner which allocates the resource element for transmitting is disclosed orthogonal frequency division multiplex (OFDM) in the system. Manner converts the resource element of one or more to two-dimensional frequency time domain; The resource element where one or more is converted physical resource block (PRB) the fact that it splits into unit is included. As for the resource element of one or more for the transmitting CSI RS PRB vis-a-vis part at least the pattern attaching and others re ru. The CSI RS resource element which possesses the identical sub-carrier index in accordance with execution configuration, vis-a-vis the common electrolysis cell is code split multiple (CDM), CDM dimension is equal to the number of CSI RS resource elements which possess the identical sub-carrier index vis-a-vis the common electrolysis cell.
