Embodiment 3

[0302] Assuming that the terminal side is a user of R11 or higher version, the base station side configures the terminal with one or more non-zero-power channel state information reference signals for channel measurement and multiple non-zero power channel state information reference signals for interference measurement and measurement through terminal-specific high-level signaling in advance. The interference measurement resources and / or the non-zero power channel state information used for interference measurement compensation refer to signal configuration information or indication information. The base station side indicates the channel measurement part information and the interference measurement part information of each channel state information process in one or more configured channel state information processes by means of index indication or bitmap sequence index indication. Wherein, the channel measurement part information of each channel state information process con...

Abstract

The invention discloses a channel state information feedback allocation method. The channel state information feedback allocation method includes the following steps that multiple sets of channel state information processes are allocated for a terminal and each channel state information process at least comprises information on a channel measurement portion and information on a disturbance measurement portion. The information on each channel measurement portion comprises a set or multiple sets of non-zero-power channel state information reference signal allocation information or indication information. The information on each disturbance measurement portion comprises at least one of the following information which includes one set or multiple sets of disturbance measurement resource allocation information or the indication information and one set or multiple sets of non-zero-power channel state information reference signal allocation information used for disturbance measurement compensation. The invention meanwhile discloses a measuring and feedback method based on the channel state information feedback allocation method and a corresponding device used for achieving the method. Uniform feedback allocation and reception can be achieved by a base station side and a terminal side in terms of channel state information feedback and flexible channel state information allocation and feedback can be achieved.

Description

technical field [0001] The present invention relates to channel state information feedback technology, in particular to a configuration method and device for channel state information feedback, a measurement method for configuration information based on channel state information feedback, and a channel state feedback method and device. Background technique [0002] After the Long Term Evolution (LTE, Long Term Evolution) system experienced several versions of R8 / 9 / 10, R11 technology was proposed again. At present, some R8 products are gradually commercialized, and R9 and R10 are subject to further product planning. [0003] After going through the stages of R8 and R9, R10 added many new features on the basis of the first two, such as demodulation reference signal (DMRS, Demodulation Reference Signal), channel state information reference signal (CSI-RS, Channel State Information Reference Signal) and other pilot characteristics, 8-antenna support and other transmission and f...
