Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a configuration method, a reporting method, a network device, and a terminal for reporting channel state information.
Background
Feedback of Channel State Information (CSI) determines the performance of MIMO (multiple input multiple output) transmission and therefore has a significant role in the overall MIMO design. In the LTE system, a plurality of different feedback types are defined in different standardized versions (Rel-8 to Rel-14) to support CSI channel information feedback of different MIMO transmission schemes. This design leads to different transmission schemes and to a dispersion and complication of information feedback. In order to avoid introducing multiple feedback types/sub-feedback types in a 5G system, a unified CSI feedback framework is considered to be designed. The system design separates the measurement resource and the measurement operation from the specific reporting operation by decoupling the CSI measurement and the CSI feedback mode, and supports the application of different MIMO transmission modes in various scenes and various frequency bands in a more flexible mode. In addition, for the emerging beam management requirements of the 5G system, information such as beam indication and corresponding RSRP (reference signal received power) also needs to be reported.
In the NR system, CSI may include CQI (channel quality indication), PMI (precoding matrix indication), CSI-RS resource indication (CRI), SS/PBCH block resource indication (SSBRI), Layer Indication (LI), RI, and L1-RSRP.
The SSBRI, the LI and the L1-RSRP are feedback quantities which are newly added on the basis of CSI feedback of the LTE system.
LI is used to indicate the strongest column in PMI for PT-RS reference signal mapping.
SSBRI and L1-RSRP are used for beam management, one indicating the beam index and the other indicating the beam strength.
According to the principle of decoupling the CSI measurement and the CSI feedback, the system configures N more than or equal to 1 Reporting feedback settings (Reporting Setting) for Reporting different measurement results and M more than or equal to 1 CSI-RS measurement Resource settings (Resource Setting) for each UE.
Each reporting feedback setting is associated to 1 or more measuring resource settings for channel and interference measurement and reporting, so that different measurement sets and reporting combinations can be flexibly set according to different terminal requirements and application scenarios.
As shown in fig. 1, two reporting settings are configured for a certain terminal, and for setting 0, the results of three measurement sets are reported, while setting 1, the result of one measurement set is reported.
The reporting feedback setting includes the following parameter configurations: CSI feedback parameters (report quality), codebook configuration, time-domain behavior of CSI feedback, frequency-domain granularity of PMI and CQI, and measurement constraint configuration. Wherein the CSI feedback parameter is used for indicating whether the UE performs beam management related feedback or CSI acquisition related feedback.
Periodic, semi-continuous and aperiodic CSI feedback modes are supported in NR. For periodic and semi-persistent CSI feedback, the feedback period and the feedback slot offset need to be configured in the reporting feedback setting, and each reporting feedback setting may be associated with 1 or 2 measurement resource settings. For aperiodic CSI feedback, the feedback slot offset is indicated by dynamic signaling, and each reported feedback setting may be associated to 1, 2, or 3 measurement resource settings.
Wideband or subband feedback is supported in NR. The size of the sub-band reported by the sub-band CSI is related to the bandwidth BWP (bandwidth part) actually used by the terminal (since the 5G system bandwidth is generally wider, the whole system bandwidth is generally divided into BWPs with different sizes from the viewpoint of power saving, etc., and each terminal transmits and receives in the allocated BWP bandwidth), as shown in the following table. The sub-band size containing 2 candidates per BWP configuration bandwidth can be configured by RRC (radio resource control). When the sub-band CSI is reported, a plurality of sub-bands can be continuously configured in the frequency domain or discontinuously configured in the frequency domain.
CSI subband size
| Bandwidth part(PRBs) | sub-Band Size (PRBs) |
| <24 | N/A |
| 24-72 | 4,8 |
| 73-144 | 8,16 |
| 145-275 | 16,32 |
The time-domain behavior of the CSI-RS in the NR may be configured as periodic, semi-persistent, and aperiodic CSI-RS.
The following table gives the combination of reporting feedback settings and measurement resource settings supported in NR. The periodic CSI report can only be associated with the periodic CSI-RS, the semi-continuous CSI report can be associated with the periodic CSI-RS and the semi-continuous CSI-RS, and the aperiodic CSI report can be associated with the periodic CSI-RS, the semi-continuous CSI-RS and the aperiodic CSI-RS.
Reporting association relation between feedback setting and measurement resource setting
Reporting feedback settings for channel or interference measurements. Each measurement resource setting comprises S which is more than or equal to 1 measurement resource setting, and each measurement resource setting comprises Ks which is more than or equal to 1 CSI-RS resource.
NR supports periodic, semi-persistent and aperiodic measurement resource settings, with time domain behavior configured in the measurement resource settings. For periodic and semi-persistent measurement resource settings, only one resource set (resource set) can be configured, i.e., S ═ 1. Aperiodic measurement resource settings may configure one or more resource sets. In order to distinguish between CSI acquisition and beam management, a beam repetition indication parameter repetition is also introduced, which is configured in a resource set for indicating whether CSI-RSs in the resource set are used for beam management and whether to employ repeated beam transmission.
The CSI feedback mechanism defined in Rel-15 is mainly for single-point transmission and coherent multi-point transmission, and does not support multi-point non-coherent transmission well.
To improve the coverage at the cell edge and provide more balanced quality of service within the service area, multipoint coordination is an important technical means in NR systems. Considering the deployment condition, the frequency band and the antenna state of the NR system, the application of the coordinated multi-point transmission technology in the NR system has a more significant practical significance. Firstly, from the perspective of network morphology, the network deployment in a manner of centralized processing of a large number of distributed access points + baseband is more beneficial to providing a balanced user experience rate, and significantly reduces the time delay and signaling overhead caused by handover. With the increase of frequency bands, relatively dense deployment of access points is also required from the viewpoint of ensuring network coverage. In the high frequency band, as the integration level of the active antenna device is increased, the modularized active antenna array is more likely to be adopted. Each antenna array of the TRP can be divided into a plurality of relatively independent antenna sub-arrays (or panels), so that the form and port number of the whole array can be flexibly adjusted according to deployment scenarios and service requirements. And the panel or the TRP can be connected by optical fibers, so that more flexible distributed deployment can be carried out. In the millimeter wave band, as the wavelength is reduced, the blocking effect generated by obstacles such as a human body or a vehicle is more remarkable. In this case, from the viewpoint of ensuring the link connection robustness, the adverse effect of the blocking effect can be reduced by performing transmission/reception from a plurality of beams at a plurality of angles by using cooperation between a plurality of TRPs or panels.
The coordinated multi-point transmission technique can be roughly divided into coherent and non-coherent transmission according to the mapping relationship of the transmission signal stream to a plurality of TRPs/panels. Wherein, in coherent transmission, each data layer is mapped onto a plurality of TRPs/panels by the weighting vector. And in non-coherent transmission, each data stream is mapped onto only a portion of the TRP/panel. Coherent transmission has higher requirements on synchronization between transmission points and transmission capability of backhaul, and is sensitive to many non-ideal factors in real deployment conditions. Relatively speaking, the non-coherent transmission is less affected by the above factors, and therefore is an important consideration for the NR multipoint transmission technique.
It should be noted that the research and standardization work for NC-JT in Rel-15 is not fully developed. However, considering that the C-JT technology under ideal backhaul (backhaul) conditions does not involve PDCCH and PDSCH design and other issues, the impact is mainly on CSI feedback. Therefore, the multi-panel codebook for C-JT was introduced in Rel-15.
In the case of cooperative transmission by multiple TRP/panels, signals transmitted by different TRP/panels may have relatively independent large-scale features, such as average delay, delay spread, average doppler shift, doppler spread, spatial domain reception parameters, and the like. In NR systems, therefore, the case where two or more reference signal channel large-scale parameters coincide is called QCL (quasi co-location). Otherwise, it is called non-QCL.
For DMRS (demodulation reference signal) ports, the concept of DMRS port group (demodulation reference signal group) may be introduced: each DMRS port QCL within a group. While provision is made in NR systems for DMRS ports in the same CDM group to have a QCL relationship. According to the presently discussed case, only two DMRS port groups are supported per data channel (e.g., PDSCH).
The CSI feedback mechanism defined in Rel-15 is mainly for single point transmission and coherent multipoint transmission, and the CSI feedback mechanism selected for dynamic transmission points is not considered separately.
