BP, UE must pass the corresponding test specifications defined by the standard organization for certain technical characteristics, such as Coordinated Multiple Point (CoMP) defined UE feedback multiple sets of channel state information (Channel State Information, CSF) Will test.

Currently, when testing the CSI feedback accuracy performance of the UE, the terminal tester first configures, for the UE, measurement resources corresponding to the CSI process corresponding to the current transmission mode, for example, a Resource Element (Re) 1-11, so that the UE can The measurement resource is used for CSI measurement, or both the terminal tester and the UE use the default Common Reference Signal (CRS) resource for CSI measurement. Then, the UE reports the CSI information to the terminal tester according to the result of the CSI measurement. In order to determine the accuracy of the CSI information reported by the UE, the terminal tester performs the test process by using the CSI information reported by the UE, and obtains the channel quality indicator (CQI) and the CQI reported by the UE during the first test. The throughput rate under the adaptive, the CQI distribution or the BLER, the throughput under the CQI adaptation is the throughput rate corresponding to the CQI; in the second test, the corresponding report is obtained according to the CQI reported by the UE under the adaptation. The value CQI is used to schedule the UE and obtain the corresponding throughput rate by using a Modulation and Coding Scheme (MCS) corresponding to the median CQI. Finally, the ratio of the throughput rate corresponding to the CQI reported by the UE to the throughput rate corresponding to the median CQI is used as the throughput rate gain, and the CSI information reported by the UE is determined according to the throughput rate gain.

FIG. 3 is a flowchart of a channel testing method according to Embodiment 3 of the present invention. As shown in Figure 3, the method includes the following process.

Step 301: The terminal tester sends the resource corresponding to the at least one CSI process to the UE. In this step, the terminal tester configures resources corresponding to at least one CSI process for the UE. The resource corresponding to each CSI process may include any one or two of the following: a non-zero-power channel state information reference signal (NZP CSI-RS) and interference measurement. Interference measurement resource (IMR). The corresponding relationship between the transmission mode and the CSI process is configured on the terminal tester, where each transmission mode may include, but is not limited to, Dynamic Point Selection (DPS) mode, Dynamic Point Blanking (abbreviation). DPB) mode, joint transmission (JT), etc.; the terminal tester only configures the resources corresponding to the CSI process to the UE, and does not notify the UE to configure the correspondence between the above transmission mode and the CSI process.

Step 302: The UE reports the CSI information corresponding to the at least one CSI process to the terminal tester according to the configured resource corresponding to the at least one CSI process.

In this step, the UE performs CSI measurement according to the configured resource corresponding to the at least one CSI process, and obtains CSI information corresponding to the at least one CSI process, and sends the CSI information to the terminal tester. Reporting CSI information corresponding to the at least one CSI process. For example, if the terminal tester configures the resources corresponding to the four CSI processes for the UE, the UE reports four sets of CSI information to the terminal tester, where each group of CSI information corresponds to one CSI process. Each group of CSI information may include any one or a combination of the following information: Modulation and Coding Scheme (Modulation and Coding Scheme, Channel Quality Indicator (CQI)) Precoding Martrix Indicator (PMI) and Rank Indicator (RI).

After step 302, step 303 and step 307 are performed. The order of execution of step 303 and step 307 is not limited, and may be performed simultaneously or sequentially, as long as it is performed after step 302.

Step 303: The terminal tester randomly selects a target CSI process, and sends parameter configuration information corresponding to the target CSI process to the UE.

In this step, the terminal tester selects the CSI process corresponding to the transmission mode as the target CSI process according to the transmission mode of the required test, and sends parameter configuration information corresponding to the target CSI process to the UE. The parameter configuration information may include a CQI, and may also include any one or a combination of the following information: PMI, Ri o

After step 303, step 304 is performed.

Step 304: The UE feeds back, to the terminal tester, a CSI parameter corresponding to the target CSI process.

In this step, the UE feeds back information to the terminal tester according to the parameter configuration information corresponding to the target CSI process, where the feedback information includes the CSI parameter corresponding to the target CSI process. Specifically, the UE feeds back the value of the CQI to the terminal tester, and may also feed back any one or a combination of the following parameters: a value of the PMI, a value of the RI.

Step 305: The terminal tester acquires and sends the target CSI process to the UE according to the CSI parameter corresponding to the target CSI process and the preset correspondence between the CSI parameter and the MCS information. Corresponding MCS information.

In this step, the terminal tester obtains the MCS corresponding to the target CSI process according to the CSI parameter corresponding to the target CSI process fed back by the UE, and according to the preset correspondence between the CSI parameter and the MCS information. The information is sent to the UE. Specifically, the terminal tester Acquiring the MCS information corresponding to the target CSI process according to the CQI fed back by the UE and according to the preset correspondence between the CQI and the MCS information, and sending the MCS information to the UE.

Step 306: The UE demodulates a physical downlink shared channel (PDSCH) according to the MCS information corresponding to the target CSI process, and reports the demodulation result feedback information to the terminal tester.

In this step, the UE demodulates the corresponding PDSCH according to the MCS information sent by the terminal tester, and reports the demodulation result feedback information to the terminal tester according to the demodulation result. If the PDSCH is correctly demodulated, the UE reports the correct feedback information (referred to as ACK). If the PDSCH is demodulated incorrectly, the UE reports the demodulated incorrect feedback information (NACK).

Step 307: The terminal tester obtains a throughput rate, a CQI distribution, and a block error ratio (BLER) corresponding to the target CSI process according to the demodulation result feedback information reported by the UE.

In this step, the terminal tester obtains the throughput rate, the CQI distribution, and the BLER corresponding to the target CSI process according to the demodulation result feedback information reported by the UE in step 306. In the embodiment of the present invention, the method for obtaining the throughput rate, the CQI distribution, and the BLER corresponding to the target CSI process by the terminal tester according to the demodulation result feedback information reported by the UE is not limited, and any method that can be reported according to the UE is not limited. The demodulation result feedback information can be applied to obtain the throughput rate, CQI distribution and BLER corresponding to the target CSI process. For example, the following method may be adopted: the terminal tester returns information according to the demodulation result of the ACK or NACK fed back by the UE, and a transport block set (Transport Block Set, referred to as TBS) for each data transmission, at a preset test time. The total number of bits in the transmission is accumulated, and the total number of bits is divided by the test time to obtain the throughput rate corresponding to the target CSI process; the terminal tester sorts according to the CQI reported in the preset test time, and obtains each The ratio of the number of CQI reports to the total number of times reported, so as to obtain the value of the CQI distribution; the terminal tester calculates the BLER according to the ratio of the number of NACKs reported by the UE and the total number of transmissions.

Step 308: The terminal tester acquires and sends the MCS information corresponding to the median CQI to the UE.

In this step, the terminal tester first obtains a median CQI according to the CSI information corresponding to the at least one CSI process reported by the UE, and then acquires the MCS information corresponding to the median CQI and sends the information to the UE. Specifically, each group of CSI information reported by the UE includes a CQI, and the terminal tester calculates a median CQI according to multiple CQIs reported by the UE. among them, There is no limitation on the specific method in which the terminal tester calculates the median CQI based on a plurality of CQIs, and any method capable of calculating the median CQI from a plurality of CQIs can be applied. For example, the terminal tester records the CQI reported by the UE, sorts the multiple CQIs according to the size, and uses the CQI located in the middle of the sorting sequence as the median CQI. The terminal tester acquires the MCS information corresponding to the median CQI according to the preset correspondence between the CQI and the MCS information, and fixes the MCS information to the UE.

Step 309: The UE demodulates the PDSCH according to the MCS information corresponding to the median CQI, and reports the demodulation result feedback information to the terminal tester.

In this step, the UE demodulates the corresponding PDSCH according to the MCS information corresponding to the median CQI delivered by the terminal tester, and reports the demodulation result feedback information to the terminal tester according to the demodulation result. If the PDSCH is correctly demodulated, the UE reports an ACK, and if the PDSCH transmission is incorrect, the UE reports a NACK.

Step 310: The terminal tester obtains a throughput rate corresponding to the median value CQI according to the demodulation result feedback information reported by the UE.

In this step, the terminal tester accumulates the correct total bits in the preset test time according to the feedback information of the demodulation result of the ACK or NACK fed back by the UE in step 309, and the TBS of each data transmission. Number, divides the total number of bits by the test time, and obtains the throughput rate corresponding to the median CQI.

After both steps 307 and 310 are performed, step 311 is performed.

Step 311: The terminal tester calculates a throughput rate gain according to a throughput rate corresponding to the target CSI process and a throughput rate corresponding to the median CQI.

In this step, specifically, the terminal tester uses the quotient of the throughput rate corresponding to the target CSI process and the throughput rate corresponding to the median CQI as the throughput rate gain.

In the third embodiment of the present invention, the terminal tester configures the resource corresponding to the at least one CSI process for the UE, and the UE reports the CSI information corresponding to the at least one CSI process to the terminal tester. In this process, since the terminal tester does not inform the UE of the transmission mode corresponding to each CSI process, although the UE knows the tested CSI process, it does not know the transmission mode corresponding to each CSI process. After the UE reports the CSI information to the terminal tester, the terminal tester verifies the accuracy of the CSI information. The specific method is as follows: The terminal tester randomly selects a CSI process, and obtains the throughput rate of the UE under the condition of reporting the CSI process. And the throughput under the condition of the median CQI, thereby obtaining the throughput gain, and determining the CSI reported by the UE according to the throughput gain The accuracy of the information. Since the UE does not know the transmission mode corresponding to each CSI process, and the terminal tester knows the transmission mode corresponding to each CSI process, in this case, the UE only has to test each CSI process according to the test procedure and report each CSI process. The CSI information, so that the terminal tester performs one configuration, the UE can report the CSI information corresponding to multiple CSI processes, and the terminal tester randomly selects the CSI information corresponding to one CSI process for accuracy verification, and can learn more reports by the UE. The accuracy of the CSI information corresponding to the CSI process avoids calculating the throughput gain of each CSI process one by one in order to verify the accuracy of the information reported by each CSI process, thereby improving the CSI test efficiency.
