The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in embodiments of the present invention means two or more, and other adjectives are similar.

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention are included in the scope of protection of the present invention.

In order to enable a terminal to calculate and obtain 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:

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

From the above, after the base station allocates multiple CSI-IM resources with different numbers for 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 CRI by using calculation modes of self configuration, which are characterized by different numbers, respectively. Particularly, under the condition that the calculation mode configured in the target terminal is poor in effect, if the base station only has the same number of the CSI-IM resources allocated to the target terminal, the target terminal only adopts one calculation mode to calculate the CRI, and the probability of obtaining accurate CRI through calculation is low. In the embodiment of the invention, multiple CSI-IM resources with different numbers are allocated, so that the target terminal can jointly calculate the CRI in multiple calculation modes, and the probability of obtaining accurate CRI by calculation can be improved. Therefore, by adopting the scheme provided by the embodiment of the invention, the terminal can calculate and obtain the accurate CRI.

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

and taking the calculated CRI with highest accuracy as the final CRI.

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 allocate different calculation modes corresponding to the different numbers to calculate CRI, and select the CRI with the highest accuracy in the calculated CRI as the final CRI. Compared with a single calculation mode, the probability of obtaining accurate CRI through calculation can be improved through different calculation modes, and therefore the accurate CRI can be obtained through calculation through the scheme provided by the embodiment of the invention.

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

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

S101: and determining the target quantity of the CSI-RS resources allocated for the target terminal.

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

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

Wherein, the numbering of the CSI-IM resources is used for: and characterizing a calculation mode adopted by the target terminal when calculating CRI. The numbering of the CSI-IM resources described above may be represented numerically.

In addition, the calculation modes corresponding to the numbers of different CSI-IM resources may be preconfigured 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 a calculation mode corresponding to the number, to obtain the CRI. The above calculation method may be any method used in the prior art for calculating CRI, which is not limited in the embodiment of the present invention.

Specifically, allocating the CSI-IM resource to the target terminal includes allocating a subcarrier corresponding to the CSI-IM resource, a corresponding symbol, a corresponding time domain position, a corresponding frequency domain position, 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 resources may also be allocated based on CSI-IM resource information entered by the user.

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

Step A: and distributing CSI-IM resources with different numbers of target numbers 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 the corresponding CSI-IM resources with the same time domain position and different frequency domain positions.

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

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

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 slots slot10, slot20, slot30, etc., respectively.

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

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

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

And (B) step (B): and distributing CSI-IM resources which correspond to the same time domain position and frequency domain position and have different numbers of the target number to the target terminal.

Specifically, the same time slot and the same RB can be allocated to different CSI-IM resources to allocate the same time domain position and the same frequency domain position to different CSI-IM resources.

Because the time domain positions corresponding to different CSI-IM resources are the same as the frequency domain positions, the time domain resources and the frequency domain resources required by the CSI-IM resources can be saved.

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

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

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

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

Wherein, the processing capability information is: information 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 the processing capability information in a terminal capability query ue capability enqiry 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 above step S103 may be implemented 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 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 capability 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 terminal capability information uecapabilityinformation 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 frequency band, the maximum number of resources per frequency band may be used as the processing capability value.

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

In one embodiment of the present invention, the above step S104 may be implemented 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 capability value is smaller than or equal to the preset capability value, the signal processing capability of the target terminal is poor, and the target terminal is difficult to calculate to obtain accurate CRI, so that multiple CSI-IM resources with different numbers can be allocated to the target terminal, the target terminal can calculate to obtain CRI based on different calculation modes, and the accuracy of CRI calculated by the target terminal is improved.

Otherwise, 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 the accurate CRI through a single calculation mode is higher, so that step S102 can be omitted, CSI-IM resources with the same number are allocated to the target terminal, and the target terminal only needs to calculate the CRI through the single calculation mode, so that the target terminal can calculate the accurate CRI, and the target terminal consumes less calculation resources in the process of calculating the CRI.

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 is indicated that the target terminal is difficult to calculate the accurate CRI by using a single calculation mode, so the base station may allocate multiple CSI-IM resources with different numbers to the target terminal, so that the target terminal calculates the CRI by using different calculation modes, thereby improving the probability of obtaining the accurate CRI by calculation. If the signal processing capability of the target terminal is stronger, it is indicated that the target terminal can calculate to obtain accurate CRI by using a single calculation mode, so that the base station can allocate multiple CSI-IM resources with the same number to the target terminal, the target terminal can calculate to obtain accurate CRI by using a single calculation mode, and the calculation resources required in the process of calculating to obtain CRI by the target terminal can be reduced.

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

S301: and receiving the configuration information of the CSI-IM resource 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 a subcarrier corresponding to the CSI-IM resource in the signal, a symbol corresponding to the signal, a time domain position and a frequency domain position corresponding to 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.

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

Specifically, the calculation mode is a configured calculation mode in the terminal, and the correspondence between each calculation mode and the number of each CSI-IM resource is recorded in the terminal. 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 CRI is calculated by adopting the calculation mode.

The calculation method of the present embodiment is not limited to this, as long as the CRI can be calculated by different calculation methods configured in different terminals.

S303: and taking the calculated CRI with highest accuracy as the final CRI.

Specifically, the calculated CRI obtained by each calculation mode may be compared, and the CRI with the highest accuracy may be used as the final CRI.

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 allocate different calculation modes corresponding to the different numbers to calculate CRI, and select the CRI with the highest accuracy in the calculated CRI as the final CRI. Compared with a single calculation mode, the probability of obtaining accurate CRI by calculation can be improved by adopting different calculation modes, so that the terminal can obtain accurate CR by adopting the scheme provided by the embodiment of the invention
