The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by persons skilled in the art based on the embodiments of the present invention are within the scope of the present invention.

In order to enable a terminal to calculate and obtain an accurate CRI, the embodiment of the invention provides a CSI-IM resource allocation method and a CRI calculation method.

The embodiment of the invention provides a CSI-IM resource allocation method, which is applied to a base station, and comprises the following steps:

determining a target number of CSI-RS resources allocated to a target terminal;

allocating a target number of CSI-IM resources with different numbers to the target terminal, wherein the numbers of the CSI-IM resources are used for: and characterizing a calculation mode adopted by the target terminal when the CRI is calculated.

As can be seen from the above, after the base station allocates a plurality of CSI-IM resources with different numbers to the target terminal, the base station may send configuration information including the numbers of the CSI-IM resources to the target terminal, and the target terminal may calculate the CRI in calculation manners that are represented by different numbers and configured by itself, because the number of calculation manners used is large, the probability of obtaining the accurate CRI by calculation is high. Especially, under the condition that the calculation mode configured in the target terminal has a poor effect, if the numbers of the CSI-IM resources distributed to the target terminal by the base station are the same, the target terminal only adopts one calculation mode to calculate the CRI, and the probability of obtaining the accurate CRI through calculation is low. The embodiment of the invention allocates various CSI-IM resources with different numbers, so that the target terminal can jointly calculate the CRI by adopting various calculation modes, and the probability of obtaining the accurate CRI by calculation can be improved. Therefore, the scheme provided by the embodiment of the invention can enable the terminal to calculate the accurate CRI.

Another embodiment of the present invention provides a CRI calculation method, which is applied to a terminal, and includes:

As can be seen from the above, the configuration information sent by the base station to the terminal includes multiple different numbers of multiple different CSI-IM resources, and the terminal may be configured to calculate the CRI in different calculation manners corresponding to the different numbers, and select the CRI with the highest accuracy from the calculated CRIs as the finally obtained CRI. Compared with the single calculation mode, the probability of obtaining the accurate CRI through calculation can be improved through different calculation modes, so that the terminal can obtain the accurate CRI through calculation by adopting the scheme provided by the embodiment of the invention.

Referring to fig. 1, a schematic flowchart of a first CSI-IM resource allocation method provided in an embodiment of the present invention is applied to a base station, where the method includes S101 to S102.

Specifically, the base station may be a base station in a 5G NR (New Radio over the air) based system.

S101: determining a target number of CSI-RS resources allocated for a target terminal.

Specifically, the CSI-RS resource may be a resource manually configured in the base station by the user. The resource numbers of different CSI-RS resources are different.

S102: and allocating CSI-IM resources with different numbers of target numbers to the target terminal.

Wherein the number of the CSI-IM resource is used to: and characterizing a calculation mode adopted by the target terminal when the CRI is calculated. The number of the above CSI-IM resources may be represented by a number.

In addition, the calculation modes corresponding to the numbers of the different CSI-IM resources may be pre-configured in the target terminal, and the calculation modes configured in different terminals may be different. After receiving the CSI-RS signal, the target terminal may process the CSI-RS signal based on the calculation method corresponding to the number to obtain the CRI. The above calculation method may be any method for calculating the CRI in the prior art, and the embodiment of the present invention does not limit this method.

Specifically, allocating the CSI-IM resources to the target terminal includes allocating subcarriers corresponding to the CSI-IM resources, corresponding symbols symbol, corresponding time domain positions and frequency domain positions, and the like.

In an embodiment of the present invention, the CSI-IM resource may be allocated by the base station based on a preset rule, and the preset rule may be determined based on a 5G protocol. The CSI-IM resource can also be allocated based on CSI-IM resource information input by a user.

In an embodiment of the present invention, the step S102 may be implemented by the following step a.

Step A: and allocating CSI-IM resources with different numbers of target numbers and corresponding to different time domain positions and/or different frequency domain positions to the target terminal.

Specifically, the different CSI-IM resources may be: and corresponding CSI-IM resources with the same time domain position and different corresponding frequency domain positions.

The different CSI-IM resources may also be: and corresponding CSI-IM resources with the same frequency domain position and different time domain positions.

The different CSI-IM resources may also be: corresponding CSI-IM resources with different frequency domain positions and different time domain positions.

Specifically, different time slots can be allocated to different CSI-IM resources, so that different time domain positions can be allocated to different CSI-IM resources.

For example, the slots allocated for different CSI-IM resources may be slot10, slot20, slot30, etc., respectively.

Different frequency domain positions can be allocated to different CSI-IM resources by allocating different RBs (Resource blocks) to the different CSI-IM resources.

For example, the RBs allocated for different CSI-IM resources may be 200, 276, etc., respectively.

In another embodiment of the present invention, the step S102 may be implemented by the following step B.

And B, step B: and allocating CSI-IM resources with different numbers of target numbers corresponding to the same time domain position and frequency domain position to the target terminal.

Specifically, the same time domain position and the same frequency domain position may be allocated to different CSI-IM resources by allocating the same timeslot and the same RB to the different CSI-IM resources.

The time domain position and the frequency domain position corresponding to different CSI-IM resources are the same, so that the time domain resource and the frequency domain resource required by the CSI-IM resources can be saved.

In addition, the manner of allocating the CSI-IM resources by the base station is the same as that in the prior art, and is not described herein again.

As can be seen from the above, after the base station allocates a plurality of CSI-IM resources with different numbers to the target terminal, the base station may send configuration information including the numbers of the CSI-IM resources to the target terminal, and the target terminal may calculate the CRI in calculation manners that are represented by different numbers and configured by itself, because the number of calculation manners used is large, the probability of obtaining the accurate CRI by calculation is high. Particularly, under the condition that the calculation mode configured in the target terminal has a poor effect, if the numbers of the CSI-IM resources allocated to the target terminal by the base station are the same, the target terminal only adopts one calculation mode to calculate the CRI, and the probability of obtaining the accurate CRI through calculation is low. The embodiment of the invention allocates a plurality of CSI-IM resources with different numbers, so that the target terminal can jointly calculate the CRI by adopting a plurality of calculation modes, and the probability of obtaining the accurate CRI by calculation can be improved. Therefore, the scheme provided by the embodiment of the invention can enable the terminal to calculate the accurate CRI.

In addition, after the base station completes the CSI-IM resource allocation for the target terminal through the embodiment shown in fig. 1, the base station may send configuration information of the CSI-IM resource to the target terminal, where the configuration information includes the number of the CSI-IM resource, so that the target terminal can determine the number of the CSI-IM resource allocated to the base station by the base station and calculate the CRI using a calculation method corresponding to the number.

Referring to fig. 2, a flowchart of a second CSI-IM resource allocation method provided in the embodiment of the present invention is shown, and compared with the embodiment shown in fig. 1, before the step S102, the method further includes the following steps S103-S104.

S103: and sending an information acquisition request aiming at the processing capacity information to the target terminal.

Wherein the processing capability information is: information for reflecting the signal processing capability of the target terminal.

In an embodiment of the present invention, the base station may carry the information acquisition request for processing capability information in a ue capability query UECapabilityEnqiry request sent to the terminal.

The processing capability information may include a maximum number of transmission ports per resource, a maximum number of resources per frequency band, a total number of transmission ports per frequency band, and the like.

In one embodiment of the present invention, the step S103 can be realized by the following step C.

Step C: and sending an information acquisition request aiming at the maximum sending port number to the target terminal.

Wherein, the maximum number of the transmitting ports is: for each resource in the signal, the maximum number of ports in the target terminal for transmitting the resource.

S104: and receiving the processing capacity information fed back by the target terminal based on the information acquisition request.

Specifically, after receiving the information acquisition request, the target terminal may carry the processing capability information in the terminal capability information UECapabilityInformaton fed back to the base station.

If the processing capability value represented by the processing capability information is less than or equal to the preset capability value, the step S102 is executed.

Specifically, if only one item of information is included in the processing capability information, the processing capability information may be directly used as the processing capability value. For example, if the processing capability information includes only the maximum number of resources per band, the maximum number of resources per band may be used as the processing capability value.

If a plurality of items of information are included in the processing capability information, an average value, a sum value, a weighted average value, a weighted sum value, or the like of the plurality of items of information may be calculated as the processing capability value. For example, if the processing capability information includes the maximum number of resources per frequency band and the total number of transmission ports per frequency band, the processing capability value may be determined as a weighted average of the maximum number of resources per frequency band and the total number of transmission ports per frequency band.

In one embodiment of the present invention, the step S104 can be realized by the following step D.

Step D: and receiving the maximum sending port number fed back by the target terminal based on the information acquisition request.

Specifically, the maximum number of transmission ports may be used as the processing capability value.

If the processing capacity value is smaller than or equal to the preset capacity value, it is indicated that the signal processing capacity of the target terminal is poor, and the target terminal is difficult to calculate to obtain an accurate CRI, so that a plurality of CSI-IM resources with different numbers can be allocated to the target terminal, so that the target terminal can calculate to obtain the CRI based on different calculation modes, and the accuracy of the CRI calculated by the target terminal is improved.

On the contrary, if the processing capability value is greater than the preset capability value, it indicates that the signal processing capability of the target terminal is better, and the probability that the target terminal can calculate to obtain an accurate CRI through a single calculation method is higher, so step S102 may not be executed, CSI-IM resources with the same number are allocated to the target terminal, and the target terminal only needs to calculate the CRI through a single calculation method, so that the target terminal can calculate to obtain an accurate CRI, and can also consume less calculation resources in the process of calculating to obtain the CRI.

As can be seen from the above, the base station determines the signal processing capability of the target terminal before allocating the CSI-IM resources to the target terminal, and if the signal processing capability of the target terminal is poor, it indicates that the target terminal is difficult to calculate to obtain an accurate CRI using a single calculation method, so that the base station may allocate a plurality of CSI-IM resources with different numbers to the target terminal, so that the target terminal calculates the CRI using different calculation methods, thereby improving the probability of obtaining the accurate CRI by calculation. If the signal processing capability of the target terminal is strong, it indicates that the target terminal can calculate to obtain accurate CRI by using a single calculation mode, so that the base station can allocate a plurality of CSI-IM resources with the same number to the target terminal, the target terminal can calculate to obtain accurate CRI by using the single calculation mode, and the calculation resources required by the target terminal in the process of calculating to obtain CRI can be reduced.

Referring to fig. 3, a schematic flowchart of a CRI calculation method provided in an embodiment of the present invention is applied to a terminal, and the method includes the following steps S301 to S303.

S301: and receiving configuration information of the CSI-IM resources sent by the base station.

The configuration information includes the numbers of the CSI-IM resources, and the numbers of different CSI-IM resources are different.

Specifically, the configuration information further includes subcarriers corresponding to the CSI-IM resources in the signal, symbols corresponding to the CSI-IM resources in the signal, time domain positions and frequency domain positions corresponding to the CSI-IM resources in the signal, and the like. The base station may allocate CSI-IM resources to the terminal based on the embodiment shown in fig. 1, which is not described herein again.

S302: and respectively adopting a calculation mode corresponding to each number contained in the configuration information to calculate the CRI.

Specifically, the calculation method is a calculation method already configured in the terminal, and the terminal records a correspondence between each calculation method and a number of each CSI-IM resource. After the terminal receives the configuration information, a calculation mode corresponding to the number of the CSI-IM resource carried in the configuration information can be determined, and the CRI is calculated by adopting the calculation mode.

The CRI calculation method according to the embodiment of the present invention is not limited to the above-described embodiment, and any CRI calculation method may be used as long as the CRI calculation method is different.

S303: and taking the CRI with the highest accuracy obtained by calculation as the finally obtained CRI.

Specifically, the CRI with the highest accuracy can be used as the finally obtained CRI by comparing the CRI calculation results calculated by the respective calculation methods.

As can be seen from the above, the configuration information sent by the base station to the terminal includes a plurality of different numbers of a plurality of different CSI-IM resources, and the terminal may be configured to calculate the CRI in different calculation manners corresponding to the different numbers, and select the CRI with the highest accuracy from the calculated CRIs as the finally obtained CRI.
