Abstract

Disclosed are a method and apparatus for mapping and receiving resources, as well as a method and apparatus for notifying and acquiring signaling. The method for mapping resources comprises: a base station maps a channel state information reference signal (CSI-RS) onto a plurality of resource elements by means of frequency division multiplexing and / or time division multiplexing and / or code division multiplexing; and / or the base station maps interference measurement resources (IMR) onto a plurality of resource elements by means of frequency division multiplexing and / or time division multiplexing. By virtue of the method and apparatus for mapping and receiving resources, as well as the method and apparatus for notifying and acquiring signaling of the present invention, the effects of improving the measurement performance of a system, ensuring more accurate self-adaptive transmission, and increasing the spectral efficiency of the system are achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a resource mapping, receiving method and device, signaling notification, and acquisition method and device. Background technique [0002] In the LTE Release R8 / R9 of the Long Term Evolution Advanced system (LTE-Advanced for short), a Common Reference Signal (Common Reference Signal) is designed to measure channel quality and demodulate received data symbols. Signal, referred to as CRS), the user equipment (User Equipment, referred to as UE) can measure the channel through the CRS, so as to determine the UE to perform cell reselection and handover to the target cell, and perform channel quality measurement in the UE connection state, when When the interference level is high, the physical layer can disconnect the connection through the high-layer-related wireless link connection failure signaling. In LTE R10, in order to further improve the average spectrum utilization rate of t...
