In order to facilitate a clearer understanding of various embodiments of the present application, some relevant background knowledge is first presented as follows.

In a New air interface 5G (NR), the spectrum range for deploying the Radio access technology is greatly expanded, and the ultra-wide transmission bandwidth and the high data rate are supported, especially in a high-frequency band scene, the base station introduces a large-scale antenna array, and improves the coverage distance of a cell through beamforming, so that multi-user space division is realized, the spectrum utilization rate is improved, and the diversified scene requirements are met.

For beamforming based on the codebook, a channel state information Reference Signal (Channel State Information-Reference Signal, CSI-RS) for downlink channel measurement needs to be allocated to a terminal, and after the terminal performs channel state information measurement, information such as channel quality indication (Channel quality indicator, CQI), CSI-RS resource indication (CSI-RS Resource Indicator, CRI), precoding matrix indication (Precoding matrix indicator, PMI) and the like is fed back, and then a base station generates a precoding matrix.

The CSI-RS is divided into two configuration strategies, namely cell-level resource configuration and user-level cell configuration. When the cell-level CSI is configured, for each terminal accessing the cell, the base station transmits one or more sets of beams corresponding to the CSI-RS resources to cover the whole cell. When the user-level CSI is configured, for each terminal accessing the cell, the base station distributes a special CSI-RS for the terminal as a reference signal for the measurement of a traffic channel of the terminal, and the direction of the CSI-RS is changed along with the change of the position of the terminal.

Compared with the fixed CSI resource overhead required by the cell-level CSI configuration, the user-level CSI configuration needs to consume more time-frequency resources, so that the cell-level CSI resource configuration with smaller resource overhead is commonly used.

In the cell-level CSI configuration, a plurality of sets of CSI resources are configured, more accurate CQI and PMI feedback can be obtained, the generated codebook is more accurate, the difference of CQI measurement capability of a terminal in the market is considered, a base station can configure fewer CSI-RS resources according to the terminal with the lowest capability, and for the terminal with high capability, the measurement resources of the terminal are wasted, and the exertion of the downlink capacity of a network is limited; the base station may also design different CSI-RS resource beams for terminals of different capabilities, but this in turn consumes larger time-frequency resources for the base station.

In order to overcome the above drawbacks, embodiments of the present application provide a method, an apparatus, an electronic device, and a storage medium for allocating channel measurement resources. The method, the device, the electronic equipment and the storage medium for configuring the channel measurement resources provided by the embodiment of the application are described in an exemplary way.

Fig. 1 is one of flow diagrams of a channel measurement resource allocation method provided by an embodiment of the present application, and as shown in fig. 1, an embodiment of the present application provides a channel measurement resource allocation method applied to a base station, where the method includes the following steps:

Step 110, determining CSI-RS resources respectively corresponding to multiple types of terminals;

Specifically, in the related art, considering the difference of CQI measurement capabilities of different terminals, the base station has the following two CSI-RS resource allocation policies to adapt to terminals with different CQI measurement capabilities.

Configuration policy 1: and the CSI-RS resources are configured by taking the lowest capacity terminal as a reference, for example, the lowest capacity terminal in the cell only supports measurement of 1 set of CSI-RS resources, the whole cell only configures one set of CSI-RS resources, and the beam can cover the whole cell.

Configuration policy 2: for terminals with different capabilities, for example, 3 capability terminals exist in a cell, and a cell commonly supports 1/2/4 set of CSI-RS resource measurement, the cell configures 1 set of CSI-RS resources for terminals supporting 1 set of CSI-RS resource measurement, configures 2 sets of different CSI-RS resources for terminals supporting 2 sets of CSI-RS resource measurement, and configures 4 sets of other CSI-RS resources different from the former 3 sets of wave beams for terminals supporting 4 sets of CSI-RS resource measurement. This requires a total of 7 different sets of CSI-RS resources to be configured for the cell configuration.

The CSI-RS resource allocation policy has different resource waste, where policy 1 does not fully utilize the measurement capability of the high-capability terminal on the channel state information, and cannot fully exert the network capability; policy 2 configures CSI-RS resources adaptive to its own capability for each type of terminal, but different users occupy different CSI-RS resources, wasting valuable physical resources.

Specifically, aiming at the problem of resource waste caused by respectively configuring different CSI-RS resources for multiple types of terminals in the existing CSI-RS resource configuration strategy, when the corresponding CSI-RS resources are configured for the multiple types of terminals, one or more identical CSI-RS resources can exist when the CSI-RS resources are configured for at least two types of terminals; wherein the CSI-RS is a reference signal for channel state information measurement.

Alternatively, different types of terminals may be divided according to the difference in CQI measurement capability of the terminals, and the CQI measurement capability of the different types of terminals may be different.

Alternatively, different classes of terminals may be divided according to differences in certain characteristics of the terminals (such as capabilities, or performances, or class of serving cell, or access base station, or application scenario, or for different user requirements).

Alternatively, any manner of dividing a plurality of terminals into different classes of terminals based on one or more characteristics may be implemented, which is not limited to this embodiment of the present application.

Specifically, the number of sets of CSI-RS resources supported by a terminal of a certain class can be determined based on the CQI measurement capability of the terminal of the certain class.

For example, the CQI measurement capability of the a-class terminal is weaker than the CQI measurement capability of the b-class terminal according to the sequence from low to high, the CQI measurement capability of the b-class terminal is weaker than the CQI measurement capability of the c-class terminal, wherein the a-class terminal supports one channel state information-reference signal (CSI-RS) resource, the b-class terminal supports two channel state information-reference signal (CSI-RS) resources, and the c-class terminal supports four channel state information-reference signal (CSI-RS) resources;

the CSI-RS resource a may be configured for the a-class terminal, the CSI-RS resources a and B may be configured for the B-class terminal, and the CSI-RS resources A, B, C and D may be configured for the c-class terminal;

the system can also configure a CSI-RS resource A for a class a terminal, can configure CSI-RS resources A and B for a class B terminal, and can configure CSI-RS resources A, C, D and E for a class c terminal;

the CSI-RS resource a may be configured for a class a terminal, the CSI-RS resources B and C may be configured for a class B terminal, and the CSI-RS resources C, D, E and F may be configured for a class C terminal.

Specifically, lossless null filling can be performed in the vertical dimension of beams corresponding to one or more identical CSI-RS resources, so that the beams corresponding to the same one or more CSI-RS resources have the capability of covering the whole cell, and the resource requirements of terminals with lower measurement precision in multiple types of terminals are met;

Specifically, after determining the first CSI-RS resources, one or more second CSI-RS resources may be determined based on all of the first CSI-RS resources; alternatively, one or more second CSI-RS resources different from any of the first CSI-RS resources are determined.

Specifically, as the first terminal having higher capability than the second terminal, the CSI-RS resources corresponding to the first terminal may include all the first CSI-RS resources and one or more second CSI-RS resources.

For example, the CQI measurement capability of the class b terminal is weaker than that of the class c terminal according to the sequence from low to high, wherein the class b terminal supports two CSI-RS resources, and the class c terminal supports four CSI-RS resources;

Specifically, a beam corresponding to a first set of CSI-RS resources is a first horizontal beam in a horizontal dimension, so that space coverage in the horizontal dimension is met; and the beams corresponding to the first set of CSI-RS resources are in a first vertical beam in the vertical dimension, so that the space coverage in the vertical dimension is satisfied.

Specifically, null filling can be performed on beams corresponding to the first set of CSI-RS resources in the vertical dimension, and null lossless beams can be obtained.

Specifically, the first type of terminal may be used as the second terminal, and the first set of CSI-RS resources may be used as the first CSI-RS resource.

Step 920, designing and configuring a second set of CSI-RS resources.

Specifically, on the basis of the beams corresponding to the first set of CSI-RS resources, the beams corresponding to the second set of CSI-RS resources are designed, and the beams can supplement the problem that the first set of beams are insufficient in local gain.

Specifically, a level difference beam in which the direction of the second horizontal beam is opposite to that of the first horizontal beam, for example, the direction of the first horizontal beam is 0 degrees and the direction of the second horizontal beam is 180 degrees, may be set. The second horizontal beam is a horizontal beam corresponding to a second set of CSI-RS resources, and the first horizontal beam is a horizontal beam corresponding to a first set of CSI-RS resources.

In particular, the first horizontal beam may be the beam in fig. 2 and the second horizontal beam may be the beam in fig. 7.

Specifically, the difference between the downtilt angle of the second vertical beam and the downtilt angle of the first vertical beam may be set equal to the width of the second vertical beam. The second vertical beam is a vertical beam corresponding to the second set of CSI-RS resources, and the first vertical beam is a vertical beam corresponding to the first set of CSI-RS resources.

Specifically, the second vertical beam may be designed to add a layer of dual beams in the vertical dimension, as shown in fig. 4 and fig. 8, and coverage enhancement may be performed on the null lossless beam in fig. 4 in the vertical dimension, to obtain the beam in fig. 8. At this time, the first vertical beam may be the null lossless beam in fig. 4, and the second vertical beam may be the beam in fig. 8.

Specifically, the first vertical beam may be a null lossless beam filled with nulls, which has a null filling effect, and the second vertical beam is not limited.

Specifically, the beams corresponding to the third set of CSI-RS resources may include a first horizontal beam and a second vertical beam, and the beams corresponding to the fourth set of CSI-RS resources may include a second horizontal beam and a second vertical beam.

Specifically, the first set of CSI-RS resources, the second set of CSI-RS resources, the third set of CSI-RS resources and the fourth set of CSI-RS resources may be used as CSI-RS resources corresponding to the third type of terminal.

It should be noted that, if a terminal with higher capability needs to add a layer of beam resources, it is also within the scope of the present application.

Compared with the first class of terminals, the channel measurement resource allocation method provided by the embodiment of the application solves the problem that the first set of CSI-RS resources are insufficient in local gain in the horizontal dimension of the second set of CSI-RS resources supported by the second class of terminals; compared with the second class of terminals, the coverage effect of beams corresponding to the first set of CSI-RS resources and the second set of CSI-RS resources is enhanced in the vertical dimension, so that the measurement requirement of the low-capacity terminals is met, and meanwhile, the high-capacity terminals supporting the measurement of the four sets of 8-port CSI-RS resources are more favorable for more accurately measuring the wireless channels.

The channel measurement resource allocation method provided by the embodiment of the application provides a differential CSI-RS resource allocation strategy for matching different terminal capacities; firstly, designing a set of wave beams corresponding to the CSI-RS resources meeting the basic coverage requirement of a cell by taking a low-capacity terminal supporting the measurement of the set of CSI-RS resources as a starting point; further, the first set of CSI-RS resources are subjected to coverage enhancement in the horizontal dimension to obtain a second set of CSI-RS resource beams, and the first two sets of resources are allocated to a terminal supporting measurement of the two sets of CSI-RS resources; then, covering and enhancing the first two sets of CSI-RS resources in the vertical dimension to obtain beams corresponding to the third CSI-RS resources and the four sets of CSI-RS resources, and configuring all four sets of resources to a terminal supporting measurement of the four sets of CSI-RS resources; the method can support more accurate measurement capability of the high-capability terminal to the channel, better exert network capability and save the resource cost of the reference signal to a certain extent.
