Description

[0001] This case is a divisional application of patent application No. 202080003795.5, filed on November 30, 2020, entitled "Measuring Data Processing Method, Apparatus, Communication Equipment and Storage Medium". Technical Field

[0002] This application relates to, but is not limited to, the field of wireless communication technology, and particularly to measurement data processing methods, apparatus, communication devices, and storage media. Background Technology

[0003] In the 3rd Generation Partnership Project (3GPP) protocol TS38.133, requirements for same-frequency and different-frequency measurements of Channel State Information-Reference Signal (CSI-RS) were introduced for radio signal measurement.

[0004] After receiving the CSI-RS measurement results reported by the UE, the base station will judge the CSI-RS measurement results based on the measurement accuracy requirements. If the UE only supports single-band Fast Fourier Transform (SFT), when the synchronization timing difference between the synchronization reference cell and the target neighbor cell exceeds a certain limit, the UE can only perform measurements based on the synchronization timing of the synchronization reference cell. Therefore, the CSI-RS measurement results of the UE for the target cell may be attenuated due to the timing difference, and there is a chance that they will be judged as unreliable.

[0068] Please refer to Figure 1This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0069] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, terminal 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0070] Base station 12 can be a network-side device in a wireless communication system. This wireless communication system can be a fourth-generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system; or it can be a 5G system, also known as a New Radio (NR) system or a 5G NR system. Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0071] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0072] Base station 12 and terminal 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0074] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0075] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0076] The execution entities involved in the embodiments disclosed herein include, but are not limited to, UEs such as mobile phone terminals that support cellular mobile communication, and base stations, etc.

[0077] One application scenario of this disclosure is that the current protocol TS38.133 only defines a set of measurement accuracy requirement parameters based on SSB. In some embodiments, these measurement accuracy requirement parameters can be used to evaluate the accuracy of CSI-RS measurement results obtained by the UE; the evaluation result can be exemplarily considered as reliable or unreliable; for example, if the measurement accuracy requirement of the base station is 20dB, and the difference between the reported CSI-RS measurement result accuracy and the measurement accuracy requirement of 20dB exceeds the deviation range, then the CSI-RS measurement result is determined to be unreliable.

[0078] There is only one set of measurement accuracy requirements in the relevant technologies, which leads to inaccurate evaluation results of CSI-RS measurement accuracy.

[0079] like Figure 2 As shown, this exemplary embodiment provides a measurement data processing method, which can be applied to a base station of a cellular mobile communication system, including:

[0080] Step 201: Determine the timing difference between the synchronization timing of the reference cell and the synchronization timing of the neighboring cell when the user equipment (UE) performs CSI-RS measurements;

[0081] Step 202: Based on the timing difference, determine the measurement accuracy requirement parameters corresponding to the CSI-RS measurement results obtained by the UE during the CSI-RS measurement.

[0082] Here, UE can be a mobile terminal or similar device that uses cellular mobile communication technology for wireless communication. Base station can be a communication device in a cellular mobile communication system that provides an access network interface to the UE.

[0083] CSI-RS can be used for downlink signal channel quality estimation during UE mobility management. CSI-RS measurement results can be used for cell selection / reselection for idle UEs or cell handover for connected UEs. For example, for idle UEs, the Reference Signal Receiving Power (RSRP) / Reference Signal Receiving Quality (RSRQ) of the CSI-RS signal can be measured, and cell selection can be performed using the S criterion, or cell reselection can be performed using the R criterion.

[0084] The UE synchronizes with a synchronization reference cell or neighboring cells based on synchronization timing and receives signals from the synchronization reference cell or neighboring cells for measurement. The UE can perform CSI-RS measurements within a timing window. Here, the neighboring cell can be the target cell for UE handover.

[0085] UEs typically perform CSI-RS measurements based on the synchronization timing of a reference cell. However, the synchronization timing of the reference cell and neighboring cells may not be identical, potentially resulting in a timing difference. When a UE measures the CSI-RS of a reference cell and neighboring cells based on the reference cell's synchronization timing, this timing difference means that the CSI-RS measured by the UE within the reference cell's synchronization window will be attenuated relative to the actual CSI-RS signal of the neighboring cell. Therefore, the CSI-RS measurement results obtained when measuring neighboring cells based on the reference cell's synchronization timing will be biased. If the same set of measurement accuracy requirements is used to evaluate the CSI-RS signal quality, inaccurate evaluation results will occur, leading to a decrease in the reliability of the measurement results reported by the UE.

[0086] Here, the measurement accuracy requirement parameters corresponding to the timing difference can be: setting different measurement accuracy requirement parameters for different timing differences, or dividing the timing difference into multiple timing difference ranges and setting different measurement accuracy requirement parameters for different timing difference ranges. Different measurement accuracy requirement parameters can be set based on signal attenuation and other factors caused by different timing differences, and can be used to accurately evaluate CSI-RS measurement results obtained under different timing differences.

[0087] The base station can determine the timing difference based on the information reported by the UE.

[0088] After the UE performs CSI-RS measurement, it can send the CSI-RS measurement results of the synchronization reference cell and / or neighboring cells to the base station. The base station can determine a set of measurement accuracy requirement parameters corresponding to the reported timing difference based on the timing difference or the timing difference range in which the timing difference is located, and use the determined measurement accuracy requirement parameters to evaluate the reported CSI-RS measurement results.

[0089] Thus, by determining the measurement accuracy requirement parameters corresponding to the timing difference, different measurement accuracy requirement parameters can be determined for different timing differences. On the one hand, this increases the flexibility in selecting measurement accuracy requirement parameters. On the other hand, when judging measurement results, the measurement accuracy requirement parameters corresponding to the timing difference can be used for evaluation, improving the accuracy of CSI-RS measurement result evaluation and thus increasing the reliability of CSI-RS measurement results.

[0090] In this embodiment of the disclosure, the base station can determine at least two measurement accuracy requirement parameters, referred to in this embodiment as a first measurement accuracy requirement parameter and a second measurement accuracy requirement parameter. The first measurement accuracy requirement parameter is different from the second measurement accuracy requirement parameter. In this embodiment of the disclosure, the first measurement accuracy requirement parameter being different from the second measurement accuracy requirement parameter means that the first measurement accuracy requirement parameter and the second measurement accuracy requirement parameter are completely different, or that the first measurement accuracy requirement parameter and the second measurement accuracy requirement parameter are not completely identical (i.e., some are the same while other parts are different). In this embodiment of the disclosure, the first measurement accuracy requirement parameter may include one or more parameters, and the second measurement accuracy requirement parameter may include one or more parameters.

[0091] In one embodiment, determining the measurement accuracy requirement parameter corresponding to the CSI-RS measurement result obtained by the UE from the CSI-RS measurement based on the timing difference includes:

[0092] In response to the timing difference being greater than or equal to the timing difference threshold, the measurement accuracy requirement parameter corresponding to the CSI-RS measurement result is the first measurement accuracy requirement parameter;

[0093] or,

[0094] In response to the timing difference being less than the timing difference threshold, the measurement accuracy requirement parameter corresponding to the CSI-RS measurement result is the second measurement accuracy requirement parameter.

[0095] Wherein, the first measurement accuracy requirement parameter differs from the second measurement accuracy requirement parameter. In this embodiment of the disclosure, the first measurement accuracy requirement parameter differs from the second measurement accuracy requirement parameter in that the first measurement accuracy requirement parameter is completely different from the second measurement accuracy requirement parameter, or the first measurement accuracy requirement parameter is not completely the same as the second measurement accuracy requirement parameter (i.e., some parts are the same while others are different). In this embodiment of the disclosure, the first measurement accuracy requirement parameter may include one or more parameters, and the second measurement accuracy requirement parameter may include one or more parameters.

[0096] Here, a timing difference threshold can be set, and the corresponding measurement accuracy requirement parameter can be determined based on the timing difference threshold. In some embodiments, the base station can determine two measurement accuracy requirement parameters: a first measurement accuracy requirement parameter can be used for CSI-RS measurement results obtained within the timing difference threshold, and a second measurement accuracy requirement parameter can be used for CSI-RS measurement results obtained outside the timing difference threshold.

[0097] The timing difference threshold can be determined based on the signal attenuation of neighboring cells when the UE is measured at different timing differences. Different measurement accuracy requirements are adopted for different signal attenuation conditions. In this way, the accuracy of CSI-RS measurement result evaluation can be improved, thereby increasing the reliability of CSI-RS measurement results.

[0098] In one embodiment, the method further includes:

[0099] Receive measurement reports carrying timing difference indication information;

[0100] The timing difference is determined based on the timing difference indication information.

[0101] After completing the CSI-RS measurements of the synchronization reference cell and neighboring cells, the UE can send the CSI-RS measurement results to the base station. The measurement results can be included in the measurement report.

[0102] The timing difference indicated by the timing difference indication information can be a specific value of the timing difference, a range of timing differences, or an indication of whether the timing difference is greater than the difference threshold.

[0103] For example, the UE can determine whether the timing difference between the synchronization timing of the synchronization reference cell and the synchronization timing of the neighboring cell is greater than a timing difference threshold, and then include the indication information indicating whether the timing difference is greater than the timing difference threshold in the measurement report.

[0104] Indication information can occupy 1 bit. For example, a "1" can indicate that the timing difference is greater than the timing difference threshold, and a "0" can indicate that the timing difference is less than or equal to the timing difference threshold. Alternatively, a "0" can indicate that the timing difference is greater than the timing difference threshold, and a "1" can indicate that the timing difference is less than or equal to the timing difference threshold. Indication information can be carried using reserved bits in the measurement report, increasing the amount of information carried in the measurement report and improving its utilization rate. Alternatively, new bits can be defined in the measurement report to carry indication information.

[0105] In one embodiment, receiving a measurement report carrying timing difference indication information includes:

[0106] Receive the measurement report that carries the timing difference indication information in the MeasResults information element of the measurement results.

[0107] The indication information can be transmitted from the UE to the base station via the MeasResults information element in the Bearer and Measurement Report. Reserved bits within the MeasResults information element can be used to carry the information, increasing the amount of information carried and improving its utilization. Alternatively, new bits can be defined within the MeasResults information element to carry the indication information.

[0108] In one embodiment, the method further includes:

[0109] The CSI-RS measurement results of the UE are evaluated based on the determined measurement accuracy requirement parameters.

[0110] Here, the CSI-RS measurement results of the UE can be evaluated based on the defined measurement accuracy requirements.

[0111] Since the measurement accuracy requirements are determined based on the timing difference, different measurement accuracy requirements can be set based on signal attenuation caused by different timing differences, which can be used to accurately evaluate CSI-RS measurement results obtained under different timing differences.

[0112] Therefore, the measurement accuracy requirements parameters can accurately evaluate the measurement results and improve the reliability of CSI-RS measurement results.

[0113] In one embodiment, evaluating the CSI-RS measurement results of the UE based on the determined measurement accuracy requirement parameters includes:

[0114] Based on the determined measurement accuracy requirement parameters, the CSI-RS measurement results carried in the MeasResults information element of the received measurement report are evaluated.

[0115] After completing the CSI-RS measurements of the synchronization reference cell and neighboring cells, the UE can send the CSI-RS measurement results to the base station. The measurement results can be included in the MeasResults information element of the measurement report.

[0116] In one embodiment, the CSI-RS measurement results include: the CSI-RS measurement results of the synchronization reference cell and / or the CSI-RS measurement results of the neighboring cell.

[0117] The CSI-RS measurement results carried in the MeasResults information element may include the CSI-RS measurement results of the synchronization reference cell and / or the CSI-RS measurement results of neighboring cells.

[0118] The base station can determine whether the timing difference is greater than the MeasResults information element based on the indication information in the MeasResults information element. Based on whether the timing difference is greater than the MeasResults information element, it selects the measurement accuracy requirement parameter and uses the selected measurement accuracy requirement parameter to evaluate the CSI-RS measurement results of the synchronization reference cell and / or the CSI-RS measurement results of neighboring cells.

[0119] Therefore, by using the measurement accuracy requirement parameters corresponding to the timing difference to evaluate CSI-RS measurement results, different measurement accuracy requirement parameters can be used to evaluate the changes in measurement results caused by timing difference, thereby improving the accuracy of CSI-RS measurement result evaluation and thus improving the reliability of CSI-RS measurement results.

[0120] like Figure 3 As shown, this exemplary embodiment provides an information transmission method, which can be applied to a UE in a cellular mobile communication system, including:

[0121] Step 301: Send a measurement report carrying timing difference indication information, wherein the timing difference indication information is used to indicate the timing difference between the synchronization timing of the synchronization reference cell and the synchronization timing of the neighboring cell when the UE performs CSI-RS measurement, so that the receiving end can determine the measurement accuracy requirement parameter corresponding to the CSI-RS measurement result obtained by the UE in performing the CSI-RS measurement based on the timing difference.

[0122] Here, the UE can be a mobile terminal or similar device that uses cellular mobile communication technology for wireless communication. The base station or other receiving end can be a communication device that provides an access network interface to the UE in a cellular mobile communication system.

[0123] CSI-RS can be used for downlink signal channel quality estimation during UE mobility management. CSI-RS measurement results can be used for cell selection / reselection for idle UEs or cell handover for connected UEs. For example, for idle UEs, the Reference Signal Receiving Power (RSRP) / Reference Signal Receiving Quality (RSRQ) of the CSI-RS signal can be measured, and cell selection can be performed using the S criterion, or cell reselection can be performed using the R criterion.

[0124] The UE synchronizes with a synchronization reference cell or neighboring cells based on synchronization timing and receives signals from the synchronization reference cell or neighboring cells for measurement. The UE can perform CSI-RS measurements within a timing window. Here, the neighboring cell can be the target cell for UE handover.

[0125] UEs typically perform CSI-RS measurements based on the synchronization timing of a synchronization reference cell. The synchronization timing of the synchronization reference cell and neighboring cells are not necessarily consistent, and a timing difference may exist. When a UE measures the CSI-RS of a synchronization reference cell and neighboring cells based on the synchronization timing of the synchronization reference cell, the timing difference causes the CSI-RS of the neighboring cell measured by the UE within the synchronization window based on the synchronization reference cell to be attenuated relative to the actual CSI-RS signal of the neighboring cell. Therefore, the CSI-RS measurement results obtained when measuring the CSI-RS of neighboring cells based on the synchronization timing of the synchronization reference cell will have deviations. If the same set of measurement accuracy requirements is used to evaluate the CSI-RS signal quality of the CSI-RS measurement results, inaccurate evaluation results will occur, thus reducing the reliability of the measurement results reported by the UE.

[0126] Here, the evaluation of measurement accuracy requirements for timing differences can be achieved by setting different measurement accuracy requirements for different timing differences, or by dividing the timing difference into multiple timing difference ranges and setting different measurement accuracy requirements for different timing difference ranges. These different measurement accuracy requirements can be set based on factors such as signal attenuation caused by different timing differences, and can be used to accurately evaluate CSI-RS measurement results obtained under varying timing differences.

[0127] The base station can determine the timing difference based on the information reported by the UE.

[0128] After the UE performs CSI-RS measurement, it can send the CSI-RS measurement results of the synchronization reference cell and / or neighboring cells to the base station. The base station can determine a set of measurement accuracy requirement parameters corresponding to the reported timing difference based on the timing difference or the timing difference range in which the timing difference is located, and use the determined measurement accuracy requirement parameters to evaluate the reported CSI-RS measurement results.

[0129] Here, a timing difference threshold can be set. CSI-RS measurement results obtained within the timing difference threshold are evaluated using a first measurement accuracy requirement parameter, while CSI-RS measurement results obtained outside the timing difference threshold are evaluated using a second measurement accuracy requirement parameter.

[0130] In this embodiment of the disclosure, the base station can determine at least two measurement accuracy requirement parameters, referred to in this embodiment as a first measurement accuracy requirement parameter and a second measurement accuracy requirement parameter. The first measurement accuracy requirement parameter is different from the second measurement accuracy requirement parameter. In this embodiment of the disclosure, the first measurement accuracy requirement parameter being different from the second measurement accuracy requirement parameter means that the first measurement accuracy requirement parameter and the second measurement accuracy requirement parameter are completely different, or that the first measurement accuracy requirement parameter and the second measurement accuracy requirement parameter are not completely identical (i.e., some are the same while other parts are different). In this embodiment of the disclosure, the first measurement accuracy requirement parameter may include one or more parameters, and the second measurement accuracy requirement parameter may include one or more parameters.

[0131] The timing difference threshold can be determined based on the signal attenuation of neighboring cells when the UE is measured at different timing differences. Different measurement accuracy requirements are adopted for different signal attenuation conditions. In this way, the accuracy of CSI-RS measurement result evaluation can be improved, thereby increasing the reliability of CSI-RS measurement results.

[0132] After completing the CSI-RS measurements of the synchronization reference cell and neighboring cells, the UE can send the CSI-RS measurement results to the base station. The measurement results can be included in the measurement report. The timing difference indication information can indicate a specific value of the timing difference, a range of timing differences, or an indication of whether the timing difference is greater than a difference threshold.

[0133] For example, the UE can determine whether the timing difference between the synchronization timing of the synchronization reference cell and the synchronization timing of the neighboring cell is greater than a timing difference threshold, and then include the indication information indicating whether the timing difference is greater than the timing difference threshold in the measurement report.

[0134] Indication information can occupy 1 bit. For example, a "1" can indicate that the timing difference is greater than the timing difference threshold, and a "0" can indicate that the timing difference is less than or equal to the timing difference threshold. Alternatively, a "0" can indicate that the timing difference is greater than the timing difference threshold, and a "1" can indicate that the timing difference is less than or equal to the timing difference threshold. Indication information can be carried using reserved bits in the measurement report, increasing the amount of information carried in the measurement report and improving its utilization rate. Alternatively, new bits can be defined in the measurement report to carry indication information.

[0135] Thus, by determining the measurement accuracy requirement parameters corresponding to the timing difference, different measurement accuracy requirement parameters can be determined for different timing differences. On the one hand, this increases the flexibility in selecting measurement accuracy requirement parameters. On the other hand, when judging measurement results, the measurement accuracy requirement parameters corresponding to the timing difference can be used for evaluation, improving the accuracy of CSI-RS measurement result evaluation and thus increasing the reliability of CSI-RS measurement results.

[0136] In one embodiment

[0137] The transmission of the measurement report carrying timing difference indication information includes:

[0138] Send the measurement report containing the timing difference indication information in the MeasResults information element of the measurement results.

[0139] The indication information can be transmitted from the UE to the base station via the MeasResults information element in the Bearer and Measurement Report. Reserved bits within the MeasResults information element can be used to carry the information, increasing the amount of information carried and improving its utilization. Alternatively, new bits can be defined within the MeasResults information element to carry the indication information.

[0140] In one embodiment, the MeasResults information element also carries the CSI-RS measurement results obtained by the UE during the CSI-RS measurement.

[0141] After completing the CSI-RS measurements of the synchronization reference cell and neighboring cells, the UE can send the CSI-RS measurement results to the base station. The measurement results can be included in the MeasResults information element of the measurement report.

[0142] In one embodiment, the CSI-RS measurement results include: the CSI-RS measurement results of the synchronization reference cell and / or the CSI-RS measurement results of the neighboring cell.

[0143] The CSI-RS measurement results carried in the MeasResults information element may include the CSI-RS measurement results of the synchronization reference cell and / or the CSI-RS measurement results of neighboring cells.

[0144] The base station can determine whether the timing difference is greater than the MeasResults information element based on the indication information in the MeasResults information element. Based on whether the timing difference is greater than the MeasResults information element, it selects the measurement accuracy requirement parameter and uses the selected measurement accuracy requirement parameter to evaluate the CSI-RS measurement results of the synchronization reference cell and / or the CSI-RS measurement results of neighboring cells.

[0145] Therefore, by using the measurement accuracy requirement parameters corresponding to the timing difference to evaluate CSI-RS measurement results, different measurement accuracy requirement parameters can be used to evaluate the changes in measurement results caused by timing difference, thereby improving the accuracy of CSI-RS measurement result evaluation and thus improving the reliability of CSI-RS measurement results.

[0146] The following provides a specific example in conjunction with any of the above embodiments:

[0147] The CSI-RS measurement evaluation methods provided in this example include:

[0148] Step 1: When the UE performs mobility measurement based on CSI-RS, it can calculate the timing difference between the two cells by measuring the synchronization timing of the synchronization reference cell and the neighboring cell, and introduce an indication message in the signaling MeasResults indicating whether the timing difference between the measurement target cell and the synchronization reference cell exceeds the defined threshold value.

[0149] Step 2: When the timing difference between the two cells exceeds the threshold value H, the indication message is TRUE; otherwise, it is FALSE. Here, the timing difference ΔT can be represented by the following expression:

[0150] △T=|T1-T2|

[0151] Where T1 represents the synchronization timing of the reference cell, and T2 represents the synchronization timing of the neighboring cell.

[0152] Step 3: The serving base station determines which CSI-RS measurement accuracy requirements to use to evaluate the reported measurement results based on the reported indication information.
