Abstract

Provided are resource mapping and receiving methods and devices and signalling notification and acquisition methods and devices. The resource mapping method includes that: an evolved NodeB (eNB) maps a Channel State Information Reference Signal (CSI-RS) onto multiple resource elements in a manner of frequency division multiplexing and/or time division multiplexing and/or code division multiplexing; and/or the eNB maps an Interference Measure Resource (IMR) onto multiple resource elements in a manner of frequency division multiplexing and/or time division multiplexing. By the technical solution, the effects of improving measurement performance of a system, ensuring more accurate adaptive transmission and improving spectral efficiency of the system are further achieved.
