Description

Measurement reporting method, device, terminal and medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on June 29, 2023, with application number 202310792128.5 and application name “Measurement Reporting Method, Device, Terminal and Medium,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a measurement reporting method, device, terminal, and medium. Background Art

[0003] In measurement reporting technologies, a measurement resource only has one type of beam information. When the network needs to measure multiple beam information, it is necessary to configure multiple measurement resources for the terminal, each with one type of beam information, so that the terminal can measure the measurement resources at different times.

[0004] In a Reconfigurable Intelligent Surface (RIS) system that considers direct transmission links, the beam information sent by the direct transmission link and the RIS forwarding link is inseparable in time, that is, one measurement resource may correspond to more than one type of beam information. If the measurement reporting mechanism in the related art is still used, the terminal will only measure the measurement results of part of the beam information sent by the network side in a single measurement, and it is unclear which beam the measurement result corresponds to. This makes it impossible for the network side to determine which link quality is better based on the terminal's report, and thus cannot maximize transmission performance.

[0116] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0117] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0118] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0119] In order to facilitate understanding of the solutions of the present disclosure, the relevant contents involved in the present disclosure are first introduced.

[0120] RIS, a candidate for the sixth-generation mobile communication technology (6G), boasts low cost, low energy consumption, programmability, and ease of deployment. RIS is an electromagnetically active surface with communication capabilities, consisting of a large-scale device array and an array control module. The array control module controls the response of each device element to wireless signals, such as amplitude, phase, frequency, and polarization. By superimposing the wireless response signals of the device elements in the large-scale device array, a specific beam propagation characteristic is formed at the macro level, thereby creating a controllable intelligent wireless environment.

[0121] Since the RIS lacks digital signal processing capabilities, a control node with digital signal processing capabilities can be introduced to control the RIS, or the network can directly control the RIS. Figure 1 shows a block diagram of a RIS system including control nodes. Each control node can control a RIS array to use beamforming technology to serve terminals. This transmission architecture is similar to the Network Controlled Repeater (NCR) technology, where the control node is equivalent to the Network Controlled Repeater-Mobile Terminal (NCR-MT) and the RIS is equivalent to the Network Controlled Repeater-Forward (NCR-Fwd). The transmission architecture used by NCR is shown in Figure 2, which does not explicitly consider the direct link between the network and the terminal, and there is no communication between the NCR-MT and the terminal.

[0122] In the related art, each reporting setting is associated with one or more channel state information (CSI) measurement settings (resource setting), a CSI measurement setting contains one or more CSI resource sets (resource set) or synchronization signal block (Synchronization Signal / PBCH Block, SSB) resource sets, a CSI resource set contains one or more CSI-RS resources, and an SSB resource set contains one or more SSB resources. Each channel state information reference signal (CSI-RS) resource or SSB resource is configured with at most one quasi-co-location (QCL) parameter.

[0123] When the network side configures the terminal (User Equipment, UE) to perform group-based measurement reporting, the UE can report N groups of beam information, each group containing information of two beams (CRI / SSB Resource Indicator (SSBRI) + Layer 1 Reference Signal Received Power (L1-RSRP) / Layer 1 Signal to Interference plus Noise Ratio (L1-SINR)). CRI / SSBRI is used to indicate the reference signal (CSI-RS resource or SSB resource) corresponding to the measurement value, and L1-RSRP / L1-SINR is used to indicate the measurement value.

[0124] When the network configures the UE to perform non-group-based measurement reporting, the UE can report N beam information, where each beam corresponds to a CRI / SSBRI and a measurement value (L1-RSRP / L1-SINR).

[0125] In NCR, the direct link between the base station and the terminal is not explicitly considered. In reality, the terminal may receive signals from both the base station and the NCR. Especially in scenarios where RIS is fully deployed, the direct link must be explicitly considered, at least during the beam measurement phase. If the direct link performance is superior, the terminal can be served without RIS. Otherwise, RIS can be used to serve the UE.

[0126] In addition, the measurement reporting methods in the related art do not consider the situation where a measurement resource has more than one type of beam information. Even if measurements need to be performed for two simultaneously transmitted links, different measurement resources are used for the measurements. In the RIS system that considers the direct link, the signal sent by the base station and the signal forwarded by the RIS are always transmitted to the UE at the same time, that is, a measurement resource has multiple beam information. If the measurement reporting mechanism in the related art is still used, the terminal will only be able to measure the measurement results of part of the beam information sent by the network side in a single measurement, and it is unclear which beam the measurement result corresponds to. For example, when the quality of the direct link is better than that of the RIS forwarding link, the terminal may only be able to measure the quality of the direct link; when the quality of the RIS forwarding link is better than that of the direct link, the terminal may only be able to measure the quality of the RIS forwarding link. This makes it impossible for the network side to determine which link has better quality based on the terminal's report, and thus cannot maximize the transmission performance.

[0127] In order to solve the above technical problems, the embodiments of the present disclosure provide a measurement reporting method, device, terminal and medium, wherein the method and device are based on the same application concept. Since the principles of solving the problems by the method and device are similar, the implementation of the device and method can refer to each other, and the repeated parts will not be repeated.

[0128] As shown in FIG3 , a flow chart of a measurement reporting method provided in an embodiment of the present disclosure, which is applied to a terminal, includes:

[0129] Step 301: receiving configuration information for at least one measurement resource sent by a network-side device;

[0130] Here, the measurement resource can be a CSI-RS resource or an SSB resource.

[0131] Step 302: measure the measurement resource based on the beam information of the measurement resource to obtain at least one measurement value corresponding to the measurement resource, wherein at least one of the measurement values ​​is associated with one or more of the at least one beam information;

[0132] The beam information of the measurement resource in this step may be beam information configured by the network, i.e., configuration information included in the above configuration information, or may be pre-set beam information. If the measurement resource has one beam information, then after the measurement is performed, the measurement resource corresponds to one measurement value, and the measurement value corresponds to the one beam information. If the measurement resource has multiple beam information, then after the measurement is performed, the measurement resource corresponds to multiple measurement values, and the multiple measurement values ​​have a corresponding relationship with the multiple beam information.

[0133] Step 303: Report at least one measurement value to the network-side device according to the configuration information or predefined rules.

[0134] The measurement reporting method of the disclosed embodiment enables the terminal to obtain measurement results of multiple beam information corresponding to the same measurement resource, either explicitly or implicitly. As a result, both the terminal and the network can clearly determine which link quality is better, the direct transmission link or the RIS forwarding link, and use the better link to serve the terminal, thereby improving the transmission performance of the system.

[0135] In some embodiments, the configuration information includes one or more of the following:

[0136] the number of beam information configured for the measurement resource;

[0137] Beam information configured for the measurement resource; wherein the beam information can be a Transmission Configuration Indication (TCI) status, a quasi-co-located QCL parameter, or a beam index. The beam index is used to represent beam information of the RIS, such as the receive beam and / or transmit beam of the RIS.

[0138] The first indication information is used to instruct the terminal to report multiple measurement values ​​corresponding to one measurement resource;

[0139] Second indication information is used to instruct the terminal to report a measurement value corresponding to a measurement resource and / or beam information corresponding to the measurement value;

[0140] A preset parameter value, where the preset parameter value is the number or number of bits of the measurement value to be reported.

[0141] In an optional embodiment, the above step 303, reporting at least one measurement value to the network-side device according to the configuration information, may specifically include:

[0142] When the measurement resource is configured with beam information and the number of the beam information is greater than 1, reporting multiple measurement values ​​corresponding to the measurement resource to the network side device;

[0143] It should be understood that when at least one measurement resource is configured with more than one beam information, the terminal reports a measurement resource index (such as a CSI-RS resource indication (CRI) or an SSB resource indication (SSBRI)) identifying the measurement resource to the network-side device, as well as multiple measurement values ​​corresponding to the measurement resource (which can be represented by the measurement resource index). Alternatively, when the terminal determines that the measurement resource corresponding to the reported measurement resource index is configured with more than one beam information, the terminal reports the measurement resource index and the multiple measurement values ​​corresponding to the resource index to the network-side device.

[0144] Alternatively, when the measurement resource is configured with beam information, and the beam information is a beam index or a quasi-co-location QCL parameter, reporting multiple measurement values ​​corresponding to the measurement resource to the network side device;

[0145] Alternatively, when the measurement resource is configured with beam information, and the beam information is a beam index or a transmission configuration indication TCI state, multiple measurement values ​​corresponding to the measurement resource are reported to the network side device.

[0146] For the latter two reporting modes of this embodiment, it should be understood that when at least one measurement resource is configured with a beam index or a QCL parameter, or when at least one measurement resource is configured with a beam index or a TCI state, the terminal reports the measurement resource index identifying the measurement resource and multiple measurement values ​​corresponding to the measurement resource to the network-side device. Alternatively, when the terminal determines that the measurement resource corresponding to the reported measurement resource index is configured with a beam index or a QCL parameter, or when the terminal determines that the measurement resource corresponding to the reported measurement resource index is configured with a beam index or a TCI state, the terminal reports the measurement resource index and multiple measurement values ​​corresponding to the resource index to the network-side device.

[0147] In an optional embodiment, the above step 303, reporting at least one measurement value to the network-side device according to a predefined rule, includes:

[0148] According to a predefined rule, when it is determined that the number of beam information of the measurement resource is greater than 1, multiple measurement values ​​corresponding to the measurement resource are reported to the network side device; or,

[0149] According to a predefined rule, when determining that the beam information of the measurement resource is a beam index or a QCL parameter, reporting multiple measurement values ​​corresponding to the measurement resource to the network side device; or,

[0150] According to predefined rules, when it is determined that the beam information of the measurement resource is a beam index or TCI state, multiple measurement values ​​corresponding to the measurement resource are reported to the network side device.

[0151] In some embodiments, the configuration information includes the first indication information; the configuration information is included in a reporting configuration, a resource configuration, or a resource group configuration.

[0152] That is, the network side configures multiple measurement values ​​corresponding to one measurement resource of the terminal. The configuration can be for the entire reporting configuration or resource configuration (such as CSI resource configuration, that is, each measurement resource (expressed by CRI / SSBRI) corresponds to multiple measurement values; or only for measurement resources configured with 2 or more beam information, multiple measurement values ​​are reported), or for resource group configuration.

[0153] In some embodiments, the configuration information includes the second indication information, and the measurement value corresponding to the measurement resource is a maximum measurement value among multiple measurement values ​​corresponding to the measurement resource.

[0154] Here, the second indication information is used to instruct the terminal to report a measurement value corresponding to a measurement resource and / or beam information corresponding to the measurement value. It should be understood that the measurement resource reported by the terminal is configured with multiple beam information, or the measurement resource is determined to have multiple beam information according to a predefined rule, and multiple measurement values ​​are corresponding to the measurement resource after measurement based on the multiple beam information. The terminal reports one of the measurement values ​​according to the second indication information, and the measurement value is the maximum measurement value among the multiple measurement values ​​corresponding to the measurement resource.

[0155] In some embodiments, the configuration information includes the second indication information; the configuration information is included in a reporting configuration, a resource configuration, or a resource group configuration.

[0156] It should be noted that the second indication information may also indicate the beam information corresponding to the measurement value reported by the terminal, such as the beam information corresponding to the reported maximum measurement value.

[0157] In some embodiments, when multiple measurement values ​​are reported to the network side device, beam information corresponding to the measurement values ​​is indicated.

[0158] When multiple measurements are reported to the network device, the corresponding beam information is indicated according to the protocol. This allows the network device to determine which link has the better measurement value based on the indicated beam information and schedule the link with the better quality to serve the terminal.

[0159] In an optional embodiment, when multiple measurement values ​​are reported to the network side device, the method of the present disclosure further includes:

[0160] Report third indication information to the network side device, where the third indication information is used to indicate beam information corresponding to the measurement value.

[0161] This embodiment uses third indication information, such as the maximum measurement value using 7-bit quantization and the other measurement values ​​using 4-bit quantization. Therefore, an N-bit indication is required in the reported information to indicate the correspondence between the maximum measurement value (non-differential measurement value, also called measurement value, i.e., measurement value using 7-bit quantization) or differential measurement value (measurement value using 4-bit quantization) and the beam information.

[0162] For example, bit 0 indicates that the maximum measurement value corresponds to beam information 1, and bit 1 indicates that the measurement value corresponds to beam information 2. For another example, bit '00' indicates that the measurement value corresponds to beam information 1, bit '01' indicates that the measurement value corresponds to beam information 2, and bit '10' indicates that the measurement value corresponds to both beam information 1 and beam information 2. That is, the measurement value is the result of a joint measurement of two beam information.

[0163] In this way, the network side device can determine which beam (link) corresponds to the maximum measurement value or the larger measurement value based on the third indication information, and then schedule the terminal to use a better link (such as a RIS forwarding link, or a network side device direct transmission link, or a RIS forwarding link and a network side device direct transmission link) for transmission.

[0164] It can be seen from the above configuration information that some measurement resources correspond to one measurement value, and some measurement resources correspond to multiple measurement values. To ensure that the bit width of the reported information is fixed, in an optional embodiment, the configuration information includes the preset parameter value. The above step 303, reporting at least one measurement value to the network-side device according to the configuration information, may specifically include:

[0165] 1. Determine the preset parameter value from the measurement values ​​corresponding to all measurement resources according to the preset rules;

[0166] The preset rules include at least one of the following:

[0167] Determine the rules for measuring values ​​to be reported based on the size of the measured values;

[0168] A rule for determining measurement values ​​to be reported is determined based on the reported measurement resource index order.

[0169] Here, the measurement resource index may be CRI or SSBRI.

[0170] This step may specifically include:

[0171] In a case where the first parameter value is greater than the preset parameter value, after sorting according to the preset rule, discarding smaller measurement values ​​that exceed the preset parameter value in the order, the first parameter value being the number of measurement values ​​corresponding to all measurement resources or the number of bits of the measurement values ​​corresponding to all measurement resources;

[0172] The remaining preset parameter value larger measurement values ​​are determined as the preset parameter value measurement values ​​to be reported.

[0173] Here, when the preset parameter value is the number of measurement values ​​to be reported, the first parameter value is the number of measurement values ​​corresponding to all measurement resources; corresponding to this situation, when the number of measurement values ​​corresponding to all measurement resources is greater than the number of measurement values ​​to be reported, after sorting according to the size of the measurement values, the smaller measurement values ​​that exceed the number of measurement values ​​to be reported in the order are discarded; or after sorting according to the measurement resource index order, the smaller measurement values ​​that exceed the number of measurement values ​​to be reported in the order are discarded; finally, the remaining larger measurement values ​​(the number is equal to the number of measurement values ​​to be reported) are reported to the network side device.

[0174] For example, the terminal plans to report four CRI / SSBRI values ​​and six measurement values: CRI 11, L1-RSRP 1 = -50dBm, L1-RSRP 2 = -80dBm; CRI 16, L1-RSRP 3 = -72dBm; CRI 8, L1-RSRP 4 = -90dBm, L1-RSRP 5 = -58dBm; and CRI 3, L1-RSRP 6 = -62dBm. The preset number of measurement values ​​is four. Based on the measurement values, the terminal determines to report the four measurement values ​​of L1-RSRP 1, L1-RSRP 3, L1-RSRP 5, and L1-RSRP 6, and their corresponding CRI values, namely CRI 11, CRI 16, CRI 8, and CRI 3. Based on the CRI index, the terminal determines to report CRI 3 (including L1-RSRP 6), CRI 8 (including L1-RSRP 4 and L1-RSRP 5), and CRI 11 (corresponding to L1-RSRP 1 and L1-RSRP 2). Since CRI 11 corresponds to two measurement values, the number of measurement values ​​exceeds the preset number. Therefore, CRI 11 can report only L1-RSRP 1, the larger measurement value. At this point, the terminal reports CRI 3 (including L1-RSRP 6), CRI 8 (including L1-RSRP 4 and L1-RSRP 5), and CRI 11 (including L1-RSRP 1).

[0175] When the preset parameter value is the number of bits of the measurement value to be reported, the first parameter value is the number of bits of the measurement value corresponding to all measurement resources; in this case, if the number of bits of the measurement value corresponding to all measurement resources is greater than the number of bits of the measurement value to be reported, after sorting the measurement values ​​by size, the smaller measurement value in the order that exceeds the number of bits of the measurement value to be reported is discarded; or after sorting by the measurement resource index order, the smaller measurement value in the order that exceeds the number of bits of the measurement value to be reported is discarded; finally, the remaining larger measurement value (the number of bits of which is equal to the number of bits of the measurement value to be reported) is reported to the network-side device. 2. Report the preset parameter value measurement value to the network-side device.

[0176] Example 1

[0177] In this embodiment, the terminal uses multiple receiving beams or the terminal performs measurement reporting on the same measurement resource based on multiple beam information assumptions.

[0178] When the terminal has the ability to use multiple beams for measurement simultaneously, it can report it to the base station through capability reporting. The base station can configure the terminal to use multiple beams or multiple beam information assumptions to perform measurement reporting on the same measurement resource through high-level parameters (such as the parameter ReceivewithmultiRX).

[0179] Each measurement resource (such as a CSI-RS resource or an SSB resource) is configured with at most two beam information, such as a QCL parameter, a beam index, or both are QCL parameters, or both are beam indexes; each measurement resource can also be configured with one beam information (the beam information can correspond to the beam information of the base station or to the information of the equivalent link, which is not limited in this disclosure).

[0180] For example, in Figure 4, only the network side (gNB) sends the beam, and the RIS does not actively adjust the beam. The terminal (UE) can receive information sent by the network side through the direct link and can also receive information forwarded by the RIS. Since the RIS does not adjust the received information of the UE, the measurement value of the measurement resource forwarded (reflected) by the RIS may be poor.

[0181] Figure 5 also shows a situation where a beam is configured. The network side aims the transmission beam at the RIS, and the RIS then aims the transmission beam at the UE.

[0182] Figures 6 and 7 are schematic diagrams of configuring two beam information. In Figure 6, both beams are sent by the network side. In Figure 7, the two beam information corresponds to the network side and RIS forwarding beams respectively.

[0183] The number of receiving beams of the UE in Figures 4 to 7 is only an example. The number of beams actually used by the UE may depend on the configuration on the network side (such as the parameter ReceivewithmultiRX mentioned earlier) or the number of beam information configured on the network side (such as when the network side configures one beam information, the UE uses one receiving beam for reception; when the network side configures multiple beam information, the UE uses multiple receiving beams for reception) or the implementation method of the UE (even if the network side configures the UE to receive beams in two beam directions at the same time, the UE can also use only one receiving beam to measure the signal).

[0184] The UE can use at least one of the following methods to report measurements, so that the network side can obtain measurement results of multiple links:

[0185] Option 1: The UE reports one or more measurement values ​​corresponding to a CRI / SSBRI according to predefined rules or network configuration.

[0186] Option 1-1: The UE reports multiple measurement values ​​corresponding to a CRI / SSBRI based on the number of beam information configured in the measurement resource and / or the content of the beam information.

[0187] For example, when at least one measurement resource in a resource set contains two beam information, the UE can report two measurement values ​​corresponding to one CRI or SSBRI, such as two L1-RSRP values, or two L1-SINR values. The two measurement values ​​correspond one-to-one to the two beam information, that is, the first measurement value corresponds to the first beam information, and the second measurement value corresponds to the second beam information. The two measurement values ​​respectively represent the measurement values ​​obtained by the UE based on the two beam information assumptions. The two beam information can be two TCI states or two QCL parameters, or one TCI state or QCL parameter and the other is a beam index. The first beam information and the second beam information can be determined according to the order in which the network configures the beam information, or according to the content of the beam information, such as when the TCI status or QCL parameter is the first beam information, corresponding to the first measurement value, and the beam index is the second beam information, corresponding to the second measurement value; or when the beam index is the first beam information, corresponding to the first measurement value, and the TCI status or QCL parameter is the second beam information, corresponding to the second measurement value. Based on the correspondence between the beam information and the measurement value, the network side can determine the measurement value corresponding to each beam information based on the UE's report.

[0188] Alternatively, when at least one measurement resource in a resource set contains two beam information, the UE can report three measurement values ​​corresponding to a CRI or SSBRI when reporting, where the first two measurement values ​​are respectively measured based on each (first or second) beam information, and the third measurement value is a measurement value measured jointly based on all beam information, such as the L1-SINR value measured using a wider receiving beam, or the L1-SINR or L1-RSRP measurement value obtained by jointly receiving two beam information, or the reported L1-SINR value reflects the interference of one beam information relative to the other beam information.

[0189] Alternatively, when the measurement resource corresponding to the CRI or SSBRI reported by the UE contains two beam information, the UE may report two or three measurement values ​​corresponding to the CRI or SSBRI when reporting the CRI or SSBRI of the measurement resource. When the measurement resource corresponding to the CRI or SSBRI reported by the UE is configured with one beam information, the UE may only report one L1-RSRP value or one L1-SINR value corresponding to the CRI or SSBRI when reporting the CRI or SSBRI of the measurement resource. In this method, the number of reported CRI / SSBRIs and the number of measurement values ​​are pre-configured by the network side to ensure that the bit width of the measurement results reported by the UE is fixed. For example, the network side configures the UE to report four CRI / SSBRIs and six measurement results, and the six measurement results are reported in a differential manner. If there are two measurement results corresponding to three CRIs / SSBRIs, there is no corresponding measurement result for the fourth CRI / SSBRI. If there are two measurement results corresponding to only one CRI / SSBRI, add all 0 bits or all 1 bits after all CRIs / SSBRIs and measurement values ​​so that the number of bits reported by the UE is equal to the number of bits configured on the network side.

[0190] Specifically, a measurement value ignoring (reporting) criterion is defined: when the number of measurement values ​​corresponding to all CRI / SSBRIs exceeds the number configured on the network side, measurement value reporting is ignored in reverse order of the CRI / SSBRIs. This means that the measurement value corresponding to the last CRI / SSBRI is ignored first. If the total number of reported bits is still higher than the number configured on the network side, the measurement value corresponding to the second-to-last CRI / SSBRI is ignored until the number of reported bits reaches the number configured on the network side. The CRI / SSBRIs can be sorted from largest to smallest by numerical value, or from smallest to largest by the maximum measurement value corresponding to the CRI / SSBRI. For example, the terminal is to report four CRI / SSBRIs and six measurement values, namely: CRI 11, L1-RSRP 1 = -50dBm, L1-RSRP 2 = -80dBm; CRI 16, L1-RSRP 3 = -72dBm; CRI 8, L1-RSRP 4 = -90dBm, L1-RSRP 5 = -58dBm; CRI 3, L1-RSRP 6 = -62dBm. The network configures the terminal to report four measurement values. The CRIs are sorted in descending order based on the maximum measurement value corresponding to each CRI: CRI 11 (corresponding to L1-RSRP 1 = -50dBm), CRI 8 (corresponding to L1-RSRP 5 = -58dBm), CRI 3 (corresponding to L1-RSRP 6 = -62dBm), and CRI 16 (corresponding to L1-RSRP 3 = -72dBm). Since CRI 11 corresponds to two measurement values ​​and CRI 8 corresponds to two measurement values, the UE reports CRI 11 and CRI 8, along with the corresponding four measurement values, in this report. Or when at least one measurement resource in a resource set is configured with a beam index or QCL parameter (or TCI state), or when the measurement resource corresponding to the CRI / SSBRI reported by the UE is configured with a beam index or QCL parameter (or TCI state), the UE reports two or three measurement values ​​corresponding to the CRI or SSBRI. The specific reporting method is similar to the previous description. Even if the network side only configures one beam information for the measurement resource, the UE can also determine the received signal quality of the beam information transmitted through different links. For example, if the beam sent by the network side is received by the UE simultaneously through the direct link and RIS forwarding, the UE can use different receiving beams to measure and report the reference signals (measurement resources) sent by the two links.

[0191] The beneficial effects are: the network side can determine the measurement results when multiple beams work together based on the UE's report, and can also obtain the results of each link, so that the network side can determine the appropriate transmission link for the UE; even if the network side only sends one beam, the UE can also determine whether using one beam or two beams for reception has better performance.

[0192] Option 1-2: The UE reports multiple measurement values ​​corresponding to a CRI / SSBRI according to the configuration on the network side.

[0193] If the network side configures the UE to report under the reporting settings (such as the high-level parameter CSI-ReportConfig), one CRI / SSBRI corresponds to multiple measurement values, and each measurement value corresponds to a reception hypothesis. If the network side configures the UE to report two measurement values, one measurement value can correspond to the measurement value of the direct link, and the other measurement value corresponds to the measurement value of the RIS forwarding link. In this case, the UE can use different receive filters to measure the measurement resource. For example, when the measurement resource is configured with a beam information (such as the beam information is the TCI status or QCL parameter of the measurement resource sent by the network side), the UE can use different receive filters to measure the received signal quality in different directions. As shown in Figure 7, the UE reports the measurement results of both receiving directions to the network side. In this case, the network side cannot determine the correspondence between the two measurement results and the receiving link based on the UE's report. If the network side wants to obtain more accurate measurement results, such as the measurement value of the direct link or the measurement value of the RIS forwarding link, it is necessary to configure more beam information for the UE or use more measurement resources for measurement reporting.

[0194] For another example, when the measurement resource is configured with two beam information, the UE can still use different receive filters for measurement, as shown in Figure 6. In this case, the two measurement results correspond one-to-one to the two beam information configured by the network side. The UE determines the reporting content according to the following method:

[0195] Method 1: Differential reporting is not used. For example, each measurement value is quantized using 7 bits. The first measurement value reported corresponds to the first beam information configured on the network side, and the second measurement value reported corresponds to the second beam information configured on the network side. For the definitions of the first and second beams, see Option 1-1.

[0196] Method 2: Use differential reporting, such as using 7-bit quantization for the maximum measurement value and 4-bit quantization for other measurement values. If the measurement value of one CRI / SSBRI is the largest, then the second beam information of the measurement resource corresponding to that CRI / SSBRI must be added to the report to indicate whether the maximum measurement value is associated with the first or second beam information. This allows the network to determine the measurement values ​​corresponding to each beam information based on the UE's report.

[0197] These two reporting methods are also applicable to reporting the measurement values ​​corresponding to the two beam information in option 1-1.

[0198] Option 2: The UE reports a measurement value and / or measurement information corresponding to multiple beam information (i.e., the preferred link between the direct link and the RIS forwarding link) according to predefined rules or network-side configuration or instructions.

[0199] If the network side configures the UE to report the measurement value of a measurement resource, the UE can use multiple receiving beams (filters) to perform measurements based on one or more beam information configured for the measurement resource, and report the larger L1-RSRP value and the beam information corresponding to the L1-RSRP value to the network side; if the network side configures two beam information for a measurement resource, beam information 1 and beam information 2, the UE uses 1 bit to indicate which of the two configured beam information the reported measurement value corresponds to for each CRI / SSBRI. For example, bit 0 represents beam information 1, and bit 1 represents beam information 2. In this way, the network side can determine which beam information has a better measurement result based on the UE's report, and then determine which link has better quality, the direct link or the RIS forwarding link. Alternatively, the UE uses 2 bits to indicate the beam information corresponding to the reported measurement value for each CRI / SSBRI. For example, bit '00' indicates that the measurement value corresponds to beam information 1, bit '01' indicates that the measurement value corresponds to beam information 2, and bit '10' indicates that the measurement value corresponds to both beam information 1 and beam information 2. In other words, the measurement value is the result of a joint measurement of the two beam information types (i.e., the network side uses the direct link and the RIS forwarding link to provide better service performance for the UE). In this way, the network side can determine which beam information measurement result has the better performance based on the UE's report, and further determine which link, the direct link or the RIS forwarding link, has better quality.

[0200] The beneficial effects are: only part of the measurement results are reported, saving signaling overhead. If the direct link quality is better, the RIS is not scheduled to serve the UE; if the RIS-related link quality is better, only the RIS link can be selected for reception, or both the RIS and direct links can be received.

[0201] The terminal can also use a group-based reporting approach to report multiple beam information or measurement results corresponding to multiple measurement resources in a single measurement report. For example, measurement resources are divided into two groups, such as two CSI resource sets, corresponding to two links respectively. The measurement resources in both measurement resource groups can be received simultaneously by the UE. This differs from measurement reporting in the multi-TP scenario in that the UE can arbitrarily select beams from the two groups of measurement resources and receive them simultaneously. However, when considering the impact of the direct link, the QCL parameters and beam index are paired. That is, the beam index is the beam index when the network uses specific QCL parameters (one or two) (the measurement results of the gNB-RIS-UE equivalent link include the impact of one or more QCL parameters sent by the gNB). Therefore, the QCL parameters and beam indexes of the two links are not completely independent. Therefore, the configuration or reporting of measurement resources can be restricted in the measurement reporting method in the multi-TP scenario.

[0202] That is, in an optional embodiment, the at least one measurement resource is pre-divided into two measurement resource groups; the above step 303, reporting at least one measurement value to the network side device according to the configuration information or predefined rules, specifically includes:

[0203] When it is determined that the number of measurement resources in the two measurement resource groups is equal, reporting two measurement resources with the same number or the same relative position in the two measurement resource groups respectively;

[0204] One or more measurement values ​​corresponding to the two measurement resources are reported to the network-side device according to the configuration information corresponding to the two measurement resources or the predefined rule.

[0205] It should be understood that the number of measurement resources in the two resource measurement groups configured by the network side is equal, and the UE selects one measurement resource for each of the two measurement resource groups in a single report. The two measurement resources are numbered identically in the two measurement resource groups, i.e., the CRI / SSBRI values ​​of the two measurement resources are identical. Alternatively, in this case, the relative positions of the measurement resources selected by the UE in the two measurement resource groups are identical, and the UE may report only one CRI / SSBRI for these two measurement resources, i.e., the reported CRI / SSBRI is applicable to both measurement resource groups.

[0206] Under this restriction, the corresponding measurement resources in the two measurement resource groups are guaranteed to be associated. For example, the two measurement resources are transmitted by the same beam of the gNB. Measurement value reporting is similar to that in the first embodiment, where the UE reports one or more measurement values ​​based on predefined rules or network-side configuration. When reporting two measurement values, each measurement value corresponds to a measurement resource group. When reporting a single measurement value, it can be the result of a joint measurement using all beam information of the two measurement resources, such as the larger of the measurement values ​​corresponding to the two beams.

[0207] In another optional embodiment, the at least one measurement resource is pre-divided into two measurement resource groups; the above step 303, reporting at least one measurement value to the network-side device according to a predefined rule, includes:

[0208] Reporting respectively two measurement resources in the two measurement resource groups that meet a first condition, wherein the first condition is that at least one of the beam information of the two measurement resources has the same beam information configuration;

[0209] Reporting the measurement values ​​corresponding to the two measurement resources that meet the first condition to the network side device.

[0210] That is, there are no restrictions on the configuration of measurement resources in the two measurement resource groups. When reporting, the UE selects one measurement resource from each of the two measurement resource groups for joint measurement. The two measurement resources in a beam group reported by the UE meet the following conditions: at least one of the beam information configurations of the two measurement resources is the same. For example, one measurement resource is configured with one beam information (such as QCL parameter 5), and the other measurement resource is configured with two beam information (such as QCL parameter 5 and beam index 3). Only when these conditions are met will the UE report the two measurement resources as a beam group.

[0211] In another optional embodiment, the at least one measurement resource is pre-divided into two measurement resource groups; and step 303, reporting at least one measurement value to the network-side device according to a predefined rule, includes:

[0212] When it is determined that the number of measurement resources in the two measurement resource groups is equal and the measurement resources are the same, reporting, according to the predefined rule, the measurement values ​​corresponding to the two same measurement resources, or the measurement value corresponding to one of the two same measurement resources, to the network side device, where the two same measurement resources belong to the two measurement resource groups respectively.

[0213] That is, the UE expects the two measurement resource groups to have the same configuration (i.e., the same number of reference signals and the same configured RSs). The UE reports the same CRI / SSBRI value in a single report, or the UE reports only one CRI / SSBRI, which applies to both measurement resource groups. This embodiment corresponds to the case where the gNB sends a single reference signal or beam, or where both hop links are measured based on the same measurement resources.

[0214] In the above embodiment, the UE is instructed to train two beams at a time, as shown in FIG8 . This may not guarantee that both receiving beams are appropriately selected, i.e., both receiving beams point to the transmitting beam. Although the reception quality is already better than that of a single link, the beamforming gain cannot be maximized. In order to maximize the beamforming gain, multiple beam information may be measured multiple times. In an optional embodiment, the at least one measurement resource is pre-divided into at least two measurement resource groups. In step 302, the measurement resource is measured based on the beam information of the measurement resource to obtain at least one measurement value corresponding to the measurement resource, including:

[0215] Based on the beam information of the measurement resources, measure the measurement resources in at least one first measurement resource group to determine a first receive beam;

[0216] The measurement resources in the second measurement resource group are measured using the first receiving beam and the second receiving beam to obtain multiple measurement values ​​corresponding to the measurement resources.

[0217] For example, when two measurement resource groups are configured (the two measurement resource groups can be in the same time slot or different time slots), the UE uses a single beam to receive and report measurements for the first measurement resource group; for the second measurement resource group, the UE uses multiple beams to receive and report measurements. Furthermore, when receiving the second measurement resource group, the UE uses the beam trained during measurement for the first measurement resource group (introducing an association between the measurement resources or their corresponding reports in the two measurement resource groups).

[0218] The measurement resource group may be a CSI resource setting (CSI resource setting), or a CSI resource set (CSI resource set) or a CSI resource subset (ie, a resource subset under a CSI resource set).

[0219] If repetition is configured as 'OFF', the UE can determine which direction or directions have better receive beam quality based on the first measurement resource group. For example, the UE reports CRI 5, CRI 12, CRI 18, and CRI 23 for the first measurement resource group, and during the measurement, the UE determines a receive beam corresponding to the above measurement resources. When the UE measures the second measurement resource group, it only selects measurement resources with the same beam information as CRI 5, CRI 12, CRI 18, and CRI 23 for measurement. The repetition of the second measurement resource group can be 'ON' or 'OFF'. The UE will use the same receive beam (filter) as when measuring the first measurement resource group, and then determine another receive beam (filter).

[0220] Taking Figure 9 as an example, the UE uses beam 1 to measure the first measurement resource group. If the second measurement resource group is configured as 'ON', the UE can train the second receive beam and select another receive beam, such as beam 2 or beam 3. If the second measurement resource group is configured as 'OFF', the UE can use another beam (such as beam 2 or beam 3) in addition to beam 1 for reception and perform another measurement on measurement resources that have the same beam information as CRI 5, CRI 12, CRI 18, and CRI 23 in the first measurement resource group (at least one beam has the same information) to determine the measurement value of the measurement resource using the other receive beam. For example, the first measurement resource group corresponds to the reference signal transmitted by the gNB, and the second measurement resource group corresponds to the reference signal forwarded by the RIS.

[0221] The first measurement (measurement of the first measurement resource group) is used to narrow the measurement range, and the second measurement is used to measure multiple beam pairs simultaneously.

[0222] Beneficial Effect: Measurements for the second measurement resource group are based on the measurement results of the first measurement resource group (e.g., the receive beam or receive filter trained by the terminal). This can result in better measurement performance or more accurate results compared to measurements performed using a single measurement resource group. The terminal can perform joint measurement reporting for both measurement resource groups.

[0223] For another example, when three measurement resource groups are configured (the three measurement resource groups can be in the same time slot or different time slots), the UE uses a single beam to receive and report measurements for the first and second measurement resource groups; and uses multiple beams to receive and report measurements for the third measurement resource group. When receiving the third measurement resource group, the UE uses the beams trained during measurements for the first and second measurement resource groups.

[0224] For example, the reference signals in the three measurement resource groups are the same. The three measurement resource groups can be resource subgroups composed of CSI-RS resources in the same CSI resource set, or they can be three CSI resource sets under the same CSI resource setting. The first and second measurement resource groups are configured with repetition = ON. The UE determines two receive beams based on the measurements of these two resource groups. The third measurement resource group is configured with repetition = OFF. When measuring the third measurement resource group, the UE scans the transmit beam based on the receive beams used when measuring the first two measurement resource groups. Alternatively, the first and second measurement resource groups are configured with repetition = OFF. The UE determines two optimal transmit beams (corresponding to beam information of one or more measurement resources) based on the measurements of these two resource groups. The third measurement resource group is configured with repetition = ON. When measuring the third measurement resource group, the UE assumes that the beam information of the resources in the third measurement resource group is configured as the optimal beam information in the measurements of the first two measurement resource groups. To achieve this goal, different measurement resource groups can correspond to different reporting settings. For example, the UE first reports the optimal beam information (CRI / SSBRI and measurement value) based on the first two measurement resource groups. After receiving the UE reported value, the gNB configures the beam information of the third measurement resource group, or directly applies the optimal beam information reported by the UE to the third measurement resource group, reducing the signaling overhead and latency caused by the configuration process.

[0225] It should be noted that the measurement reporting method provided in the present disclosure is not only applicable to RIS systems, but also to relay systems, NCR systems, and conventional single-hop (gNB-UE communication) systems with multiple beams.
