Channel state information measuring method and device

The invention belongs to the field of communication technologies, and in particular relates to a channel state information measuring method and device.

In view of the important role of Multiple Input Multiple Output (MIMO) technology in improving peak rate and system spectrum utilization, the existing Long Term Evolution (LTE)/Long Term Evolution (LTE-Advanced, LTE-A) The radio access technologies are all based on MIMO + Orthogonal Frequency Division Multiplexing (OFDM) technology. In addition, since the performance gain of MIMO technology comes from the spatial freedom that multi-antenna systems can obtain, an important evolution direction of MIMO technology in the development of standardization is the expansion of dimensions.

In a base station antenna system using a conventional Passive Antenna System (PAS) structure, a plurality of antennas (each corresponding to an independent RF-IF-baseband channel) are horizontally arranged, wherein each多个 The corresponding vertical dimension is connected by RF cable. Therefore, the existing MIMO technology can only achieve the horizontal dimension of each chirp by adjusting the relative amplitude/phase of different turns in the horizontal dimension. The optimization of the spatial characteristics can only be achieved by a uniform magnetic domain level in the vertical dimension. And introducing active in mobile communication systems After the Antenna System (AAS) technology, the base station antenna system can obtain greater degrees of freedom in the vertical dimension to achieve signal optimization at the User Equipment (UE) level in three dimensions.

Based on the above situation, the industry is further advancing MIMO technology in the direction of three-dimensionalization and large-scale. At present, 3GPP is carrying out research projects on 3D channel modeling, and it is expected to continue to carry out 8 Elevation Beamforming (EBF) and more than 8 埠 (such as 16, 32 or 64). Research and standardization of Full Dimension MIMO (FD-MIMO) technology. The academic community is more forward-looking in research and testing of MIMO technology based on larger antenna arrays (containing one hundred or hundreds, or even more). Academic research and preliminary channel measurement results show that massive MIMO (large-scale multi-input and multi-out) technology will greatly improve system bandwidth utilization efficiency and support a larger number of access users. Therefore, major research organizations regard massive MIMO technology as one of the most promising physical layer technologies in next-generation mobile communication systems.

However, in MIMO technology, especially for multi-user MIMO (MU-MIMO) technology, the channel state information accuracy that can be obtained by the network side directly determines the accuracy of precoding/beamforming. The performance of the scheduling algorithm affects the overall system performance. Therefore, the acquisition of channel state information has always been one of the core issues in the standardization of MIMO technology. For the Frequency Division Duplexing (FDD) system, because there is a large frequency interval between the uplink and downlink, it is generally difficult to obtain the downlink channel status information directly through the measurement of the uplink channel, so the existing FDD is available. The system generally adopts a mechanism for measuring and feeding back Channel State Information (CSI) based on a downlink reference signal. In this case, the spatial resolution of the channel status information is directly dependent on the reference. The number of signals. When the size of the antenna array is large, if a new reference signal is introduced to ensure downlink, significant time-frequency resource overhead will be incurred. However, if the reference signal is limited, the spatial resolution of the downlink channel state information measurement cannot be guaranteed, and the performance advantage of massive MIMO cannot be exerted. If the mechanism of the multi-CSI process is used, the channel state information reference signal (CSI-RS) corresponding to the process is used in each process to perform channel estimation on a specific antenna, although 3D can be implemented. Channel measurement. However, CSI-RS based multi-CSI processes will also increase the reference signal overhead.

In order to facilitate the understanding of the above technical solutions of the present invention, the above technical solutions of the present invention will be described in detail from three aspects of CSI measurement mode, CSI reporting mode, and CSI calculation and feedback.

In the LTE/LTE-A system, the physical mode includes a Physical Downlink Shared Channel (PDSCH) transmission mode (Transmission Mode, TM) 1-7, and a L1/2 (Layer 1/2) control information physics. The Physical Downlink Control Channel (PDCCH) and the Physical Broadcast Channel (PBCH) that transmit broadcast information use CRS-based transmission and channel state information measurement mechanisms. Although in the development of the LTE/LTE-A system, with the separation of the measurement and transmission functions of the reference signal, the CRS is gradually being used by the CSI-RS and the UE-specific reference signal in the newly introduced PDSCH TM8-10 (UE-specific Reference) Signal, URS), but in terms of compatibility, or from the perspective of control and broadcast information transmission, in LTE The CRS is still indispensable in the subsequent evolution version, but the measurement and feedback mechanism of the currently defined multi-CSI process can only use the CSI-RS and cannot use the reference signal that must be transmitted in each subframe of the CRS.

The roadside terminal is configured to report the type of CSI (such as subband, broadband, Precoding Matrix Indication (PMI), or non-PMI, etc.) and the reported start time and period, so that the terminal can start according to the type. The CSI and so on are reported at the beginning and the time.

For the CSI calculation and feedback mechanism, the present invention utilizes the CSI measurement mode configured by the terminal to the network side to perform measurement, and simultaneously calculates the CSI, and the specific manner of calculating the CSI can be divided into three types, one of which is independent calculation and feedback, and the specific For calculation, the CSI may be separately calculated according to the measurement of the reference signal corresponding to each CSI process (mainly for the first measurement mode), and may also be separately measured according to the CSI-RS corresponding to each CSI process. The CSI is calculated, and the CSI is calculated according to the measurement of the CRS (mainly for the second measurement mode); for the feedback, all the CSIs can be selected for feedback, or the CSI of the local thread can be selected according to actual requirements. Give feedback. The other is unified computing and feedback. Specifically, unified CSI is obtained according to the measurement of all available reference signal resources (possibly including Rank Indication (PMI/RI)/Channel Quality Indicator (CQI).
