Embodiment Construction

[0025] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] An embodiment of the present invention provides a CSI report collision processing method to solve the problem of multiple CSI report collisions, such as figure 1 As shown, the method includes the following steps:

[0027] Step 101, the network side (such as the base station) determines priority information of CSI (CSI measurement set).

[0028] Wherein, the base station may determine the CSI priority information according to one or any combination of the terminal's home cell...

Abstract

The invention discloses a method and equipment for processing CSI (Channel State Information) reporting collision. According to the technical scheme provided by the embodiment of the invention, by determining the priory information of different CSI, only the CSI with optimal priory information in CSI having CSI reporting collision is reported by a terminal when the CSI reporting collision occurs,thus the behaviour of the terminal can be ensured in CSI reporting collision.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and equipment for processing collisions reported by CSI. Background technique [0002] In the LTE (Long Term Evolution, long-term evolution) system, the base station side obtains the downlink channel state information through the CSI (Channel State Information) report of the terminal, and then realizes functions such as transmission mode selection and adaptive scheduling. [0003] In the R8 version, the channel state is considered to be stable, so each terminal only reports one CSI at a time; the way of periodic CSI feedback is determined by the base station, and through the CQI- ReportConfig notifies the terminal, including the specific feedback cycle and feedback location. [0004] With the introduction of CA (carrier aggregation), TDM (Time Domain Mode, time domain mode) eICIC (enhance Inter-cell interference coordination, enhanced inter-cell interfe...
