Description

Methods for submitting and receiving measurement reports, and methods for receiving and sending measurement configurations. Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method for reporting and receiving measurement reports, and a method for receiving and sending measurement configurations. Background Technology

[0002] With the development of wireless communication technology, wireless network communication scenarios can be divided into near-field communication scenarios and far-field communication scenarios.

[0003] In related technologies, when terminal devices report measurement results of reference signals, it is usually based on a far-field communication scenario. However, when the antenna array of the network device is a very large-scale multiple-input multiple-output (MIMO) array, there is a high probability that near-field effects will occur. That is, the communication scenario between the terminal device and the network device is a near-field communication scenario.

[0004] Because electromagnetic waves in far-field communication are plane waves, while those in near-field communication are spherical waves, there are differences between the two. Therefore, how to report measurement results in near-field communication scenarios remains an unsolved problem. Summary of the Invention

Depending on the context, the word “if” as used herein may be interpreted as “when”, “when”, or “in response to determination”.

[0072] Next, let's introduce the relevant technologies:

[0073] Channel State Information (CSI) Feedback

[0074] To enable network devices to perform reasonable scheduling, terminal devices need to feed back downlink channel state information (CSI) so that the base station can determine the terminal's scheduling information, such as the transmission layer number, precoding matrix, transmit beam, and modulation / coding scheme. Specifically, the terminal device's CSI reporting is based on the CSI reporting configuration indicated by the network device and the Channel State Information Reference Signal (CSI-RS) sent by the network device. The uplink resources used by the terminal device for CSI reporting and the CSI-RS used for CSI measurement are both indicated by the CSI reporting configuration. Each CSI reporting configuration corresponds to one CSI report, and each CSI report can contain different information such as the CSI-RS Resource Indicator (CRI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), and Channel Quality Indicator (CQI). This information is obtained based on the CSI-RS configured and sent by the network device. Specifically, the content / information included in the CSI is determined by the report quantity information in the CSI reporting configuration. This reported information can indicate one of CRI, RI, PMI, CQI, Reference Signal Received Power (RSRP), or Layer Indicator (LI).

[0075] CRI is used to determine the CSI-RS resource currently used for channel measurement and the interference measurement resource currently used for interference measurement from multiple CSI-RS resources; RI is used to report the recommended number of transport layers; PMI is used to determine the recommended precoding matrix from a predefined codebook; CQI is used to report the current channel quality; RSRP is used to report the RSRP of the SSB or CSI-RS corresponding to the fed-back index, so that the network side can determine the beam used for downlink transmission; LI is used to report the index of the transport layer associated with the Phase-Tracking Reference Signal (PTRS).

[0076] The RI / PMI / CQI can be determined based on the signal-to-interference-plus-noise ratio (SINR) estimated by the terminal device. The channel component of SINR is determined based on the non-zero power CSI-RS configured by the network device for channel measurement, while the interference component is determined based on the Channel State Information-Interference Measurement (CSI-IM) or non-zero power CSI-RS configured by the network for interference measurement. The CSI-RS resources used for channel measurement can include multiple antenna ports to measure the complete downlink channel and thus calculate the CSI.

[0077] Terminal devices can report CSI in three periodic ways: periodic CSI, semi-persistent CSI, and aperiodic CSI. For example, as shown in Figure 1(a), periodic CSI is transmitted on the Physical Uplink Control Channel (PUCCH), and its CSI reporting configuration is configured by Radio Resource Control (RRC). After receiving the corresponding RRC configuration, the terminal device periodically reports the CSI. For example, as shown in Figure 1(b) and (c), semi-persistent CSI can be transmitted on the PUCCH or the Physical Uplink Shared Channel (PUSCH). The CSI reporting configuration corresponding to the CSI transmitted on the PUCCH is pre-configured by RRC signaling and activated or deactivated by Media Access Control (MAC) layer signaling. The CSI reporting configuration corresponding to the CSI transmitted on the PUSCH is dynamically indicated (activated or deactivated) by Downlink Control Information (DCI) signaling. After receiving activation or indication signaling for network configuration, the terminal device periodically transmits CSI on the PUCCH or PUSCH until it receives deactivation signaling and stops reporting. For example, as shown in Figure 1(d), the CSI reporting configuration corresponding to non-periodic CSI reporting is also pre-configured via RRC signaling. Part of this configuration can be activated via MAC layer signaling, and then the CSI reporting configuration used for CSI reporting is indicated via CSI trigger signaling in the DCI. Upon receiving the CSI trigger signaling, the terminal device reports the corresponding CSI on the scheduled PUSCH in one go according to the indicated CSI reporting configuration.

[0078] Beam reporting

[0079] Based on the measurement results, the terminal device reports K≥1 pieces of information to the network device. Each piece of information includes beam indication information (e.g., CSI-RS resource identifier, Synchronization Signal Block (SSB) number) and the corresponding Layer 1 Reference Signal Received Power (L1-RSRP) information. When K>1, the quantized result of the maximum value among the K L1-RSRP values ​​is reported directly, while the differences between the other K-1 L1-RSRP values ​​and the maximum L1-RSRP value are quantized and reported; that is, the difference values ​​of the other K-1 L1-RSRP values ​​are reported. The reporting process is similar for L1-SINR measurements.

[0080] Depending on whether the terminal device can receive data transmitted simultaneously on K downlink beams, the reporting methods for beam measurement results can be divided into the following two categories:

[0081] • Non-group based reporting.

[0082] • Group-based reporting.

[0083] In non-group-based reporting, the terminal device performs measurements based on N reference signals configured by the network device. Based on the measurement results, it selects and reports K pieces of information, where K is configured by the network device and can be 1, 2, 3, or 4. The K reference signals correspond to K beams. The network device cannot simultaneously transmit signals from multiple beams among the K beams to the terminal device because the terminal device cannot simultaneously receive signals transmitted from multiple downlink beams. When reporting K pieces of information, the terminal device can select K from the N reference signals according to its own implementation algorithm. For example, it can consider only the K with the strongest L1-RSRP, or it can consider the direction of arrival of different beams (i.e., considering the spatial correlation between different received reference signals) to select K. For instance, downlink beam reporting can be achieved by reporting up to 4 CRIs or SSB Resource Indicators (SSBRIs).

[0084] Group-based reporting first requires the terminal device to have the ability to simultaneously receive multiple downlink transmission beams. When the network device configures the terminal device to perform group-based reporting, the terminal device performs measurements based on N reference signals configured by the network device. Based on the measurement results, it selects to report K=2 pieces of information, where each piece of information includes indication information of the reference signal and the corresponding L1-RSRP information. The network device can simultaneously transmit data with the terminal device from the reported K=2 beams.

[0085] It should be noted that the "group" here can also be understood as an "information group". Group-based reporting can also be understood as: the terminal device reporting multiple measurement information in the form of an information group.

[0086] In some embodiments, the measurement information reported by the terminal device to the network device also includes the Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR). Compared to L1-SINR, the advantages of using L1-RSRP as the measurement quantity are as follows:

[0087] L1-RSRP measurements are simple, have low complexity, and are easy to implement in terminals.

[0088] L1-RSRP measurements primarily reflect the channel quality corresponding to the downlink beam. Their changes are relatively slow, making it easier to select a reliable downlink beam with relative stability. In contrast, interference changes rapidly, which means that L1-SINR fluctuates more, and using it for beam measurement may lead to frequent beam switching.

[0089] In MIMO transmission schemes, CSI feedback already exhibits interference-related characteristics. Therefore, beam management based on L1-RSRP combined with CSI feedback can achieve the same purpose as L1-SINR.

[0090] Compared to L1-RSRP, the additional gain provided by L1-SINR is not significant, and in some cases it may even lead to performance loss.

[0091] The advantages of using L1-SINR as the measurement quantity are:

[0092] The quality of downlink beam reception depends not only on the quality of the corresponding channel but also on interference. L1-RSRP cannot truly reflect beam transmission quality. Therefore, measurements based on L1-SINR can better account for interference between beams.

[0093] The combination of L1-RSRP measurement and CSI feedback requires two separate processes: beam management and CSI measurement feedback. However, using L1-SINR allows for user pairing to be completed in a single process.

[0094] L1-SINR can help the network coordinate the downlink transmission beams used by different cells or different Transmission Reception Points (TRPs), thereby improving the overall system performance.

[0095] Figure 2 shows a schematic diagram of a communication system provided in an exemplary embodiment of this application. The communication system includes a terminal device 110 and a network device 120.

[0096] The terminal device 110 in this application may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device.

B, gNB) or transmission point (TRP or TP), or, in a 5G system, one or a group of antenna panels (including multiple antenna panels) of a base station, or, network nodes constituting a gNB or transmission point, such as baseband unit (BBU) or distributed unit (DU), or base stations in Beyond Fifth Generation (B5G) mobile communication systems or 6G mobile communication systems, or core network (CN), fronthaul, backhaul, radio access network (RAN), network slicing, etc., or serving cell, primary cell (Pcell), primary secondary cell (PSCell), special cell (SpCell), secondary cell (Scell), neighboring cell, etc. of terminal equipment.

[0098] Terminal device 110 and network device 120 communicate with each other via some air interface technology, such as the Uu interface. For example, there are two communication scenarios between terminal device 110 and network device 120: uplink communication and downlink communication. Uplink communication refers to terminal device 110 sending signals to network device 120; downlink communication refers to network device 120 sending signals to terminal device 110.

[0099] The technical solutions provided in the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Advanced Long Term Evolution (LTE-A) systems, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication systems, 5G mobile communication systems, NR systems, evolution systems of NR systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, Terrestrial Networks (TN) systems, Non-Terrestrial Networks (NTN) systems, and Wireless Local Area Networks (WLANs). Networks (WLAN), Wi-Fi, cellular IoT systems, cellular passive IoT systems, and can also be applied to subsequent evolution systems of 5G NR systems, as well as B5G, 6G and subsequent evolution systems.

[0100] In some embodiments of this application, "NR" may also be referred to as a 5G NR system or a 5G system. The 5G mobile communication system may include Non-Standalone (NSA) and / or Standalone (SA) networking. The technical solutions provided in the embodiments of this application can also be applied to Machine-Type Communication (MTC), Long Term Evolution-Machine (LTE-M) technology, Device-to-Device (D2D) networks, Machine-to-Machine (M2M) networks, Internet of Things (IoT) networks, or other networks. For example, an IoT network may include a vehicle-to-everything (V2X) network. In this context, the communication methods in the vehicle-to-everything (V2X) system are collectively referred to as vehicle to other devices (V2X, where X can represent anything). For example, V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian (V2P) communication, or vehicle to network (V2N) communication, etc.

[0101] For future 6th-generation (6G) communication networks, larger antenna apertures and higher frequency bands (e.g., centimeter waves, millimeter waves, and terahertz) will be adopted, making near-field characteristics more pronounced. Furthermore, the introduction of emerging technologies such as reconfigurable intelligent surfaces (RIS), massive multiple-input multiple-output (MIMO), movable antennas, and cell-free networks will make near-field scenarios more prevalent in future wireless networks. In near-field scenarios, due to changes in electromagnetic wave propagation characteristics, they can no longer be simply approximated as plane waves but must be considered as spherical waves. From the perspective of space resource utilization, although traditional wireless communication systems have achieved significant success in the exploration and utilization of far-field space resources, further exploration and application of near-field space resources are expected to bring new physical space dimensions to wireless communication systems.

[0102] The following method is commonly used in academia to divide the near-field and far-field regions:

[0103] Assuming the antenna aperture is D and the wavelength is λ, then For the far field, the wavefront approximates a plane wave; For near-field radiation, the wavefront is a spherical wave. r represents the distance between the terminal device and the network device.

[0104] In related technologies, the introduction of large-scale antenna arrays not only improves the system capacity and coverage of communication systems but also significantly shortens the near-field communication area. It should be understood that the near-field communication area described in the embodiments of this application is a concept corresponding to the far-field communication area. The near-field communication area refers to the communication coverage area relatively close to the network device; it can also be called the near-field region, near-field communication range, or near-field range. The far-field communication area refers to the communication coverage area relatively far from the network device; it can also be called the far-field region, far-field communication range, or far-field range.

[0105] In some embodiments, in the near-field communication region, due to the change in electromagnetic wave propagation characteristics, the near-field beam can no longer be simply approximated as a plane wave like the far-field beam, but must be considered as a spherical wave. For example, as shown in FIG3, the near-field beam in the near-field communication region is a spherical wave beam, and the far-field beam in the far-field communication region is a plane wave beam; the near-field beam and the far-field beam are different.

[0106] In related technologies, terminal devices typically report measurement results of reference signals based on far-field communication scenarios. However, when the antenna array of a network device is a MIMO antenna array, there is a high probability of near-field effects occurring. That is, the communication scenario between the terminal device and the network device becomes a near-field communication scenario. In this case, if the antenna array of the network device is divided into multiple antenna groups, the communication between each antenna group and the terminal device is still approximately a far-field channel, which can reduce the complexity of beam reporting. On the other hand, due to the non-stationary nature of space, some antenna ports of the network device's antenna array are invisible to the terminal device. Therefore, the terminal device only needs to report the beams of the visible antenna groups, which can also reduce the complexity of beam reporting.

[0107] Based on this, embodiments of this application provide a method for reporting measurement reports, which can reduce the complexity of beam reporting. As shown in Figure 4, this method is executed by a terminal device and includes:

[0108] Step 220: The terminal device reports a measurement report, which indicates the measurement results corresponding to one or more antenna groups.

[0109] In some embodiments, the measurement report is used to indicate the measurement results of one or more reference signals corresponding to each antenna group. The one or more reference signals are configured by the network device or selected by the terminal device.

[0110] It should be understood that the "measurement report" in this application embodiment is based on the "antenna group". The "antenna group" in this application embodiment can also be replaced by "antenna port group", "reference signal resource set", or "reference signal resource". The reference signal resource set includes at least one of the following: CSI-RS resource set, Channel Sounding Reference Signal (SRS) resource set, SSB resource set, and Tracking Reference Signal (TRS) resource set. Each reference signal resource set corresponds to one antenna group. The reference signal resources include at least one of the following: CSI-RS resources, SRS resources, SSB resources, and TRS resources.

[0111] In some embodiments, one or more antenna groups include all of the N antenna groups, where N is a positive integer.

[0112] In some embodiments, one or more antenna groups include a subset of N antenna groups, where N is a positive integer. The terminal device only reports the measurement results corresponding to a subset of the antenna groups, which solves the problem that some antenna ports of the network device's antenna array are invisible to the terminal device due to spatial non-stationarity. That is, the terminal device only needs to report the measurement results corresponding to the visible subset of antenna groups.

[0113] The N antenna groups are obtained by dividing the antenna array of the network device. The N antenna groups are the antenna groups indicated by the network device to the terminal device through measurement configuration. Optionally, the antenna ports corresponding to the N antenna groups belong to the same antenna array. Optionally, the N antenna groups are all the antenna groups obtained by dividing the MIMO antenna array within the network device. Or, the N antenna groups are a portion of the antenna groups obtained by dividing the MIMO antenna array within the network device.

[0114] For example, as shown in Table 1 below:

[0115] Table 1

[0116] Suppose that the network device's antenna array includes {antenna port 1, antenna port 2, antenna port 3, antenna port 4, antenna port 5, antenna port 6, and antenna port 7}. {antenna port 1, antenna port 2, and antenna port 3} are designated as antenna group 1, {antenna port 4 and antenna port 5} as antenna group 2, and {antenna port 6 and antenna port 7} as antenna group 3. For example, if the network device sends measurement configuration instructions for all three antenna groups to the terminal device, then N = 3.

[0117] For example, in the case where one or more antenna groups include all of the N antenna groups, the one or more antenna groups include the three antenna groups shown in Table 1 above.

[0118] For example, in the case where one or more antenna groups include a portion of N antenna groups, the one or more antenna groups include one or two of the three antenna groups shown in Table 1 above.

[0119] In some embodiments, the number of antenna ports in different antenna groups is the same. For example, antenna group 2 and antenna group 3 shown in Table 1 above both include 2 antenna ports.

[0120] In some embodiments, the number of antenna ports in different antenna groups is different. For example, antenna group 1 and antenna group 2 are shown in Table 1 above. Antenna group 1 includes 3 antenna ports, and antenna group 2 includes 2 antenna ports.

[0121] In some embodiments, there may be one or more measurement reports. For example, a terminal device may submit measurement reports multiple times at different times.

[0122] In some embodiments, one antenna group corresponds to one beam.

[0123] In summary, the method provided in this embodiment allows the terminal device to report measurement results corresponding to one or more antenna groups on a per-antenna-group basis, thereby enabling the terminal device to perform beam reporting based on antenna groups. Since the relationship between each antenna group and the terminal device can be approximated as a far-field channel, reporting measurement results based on antenna groups helps to reduce the complexity of beam reporting.

[0124] In some embodiments, before reporting a measurement report, the terminal device needs to receive the measurement configuration from the network device, and then perform the measurement according to the instructions in the measurement configuration. As shown in Figure 5, the above method further includes:

[0125] Step 320: The terminal device receives the measurement configuration, which is used to indicate one or more reference signal resources corresponding to the N antenna groups.

[0126] In some embodiments, the measurement configuration is sent by the network device to the terminal device. The network device can configure the terminal device to report based on the measurement configuration. Optionally, the measurement configuration is provided by the network device via dedicated signaling, which is RRC signaling, including RRCReconfiguration, RRCResume, or CSI-ReportConfig.

[0127] In some embodiments, the measurement configuration includes at least one of the following parameters:

[0128] 1. Measurement Object: A list of objects to be measured by the terminal device. For example, the measurement object may indicate N antenna groups. Optionally, the measurement object may directly indicate N antenna groups. Alternatively, the measurement object may be used to indirectly indicate N antenna groups. For instance, by configuring N sets of reference signal resources corresponding to N antenna groups. Or, for another example, by configuring a set of reference signal resources containing M reference signal resources, each of which belongs to one of the N antenna groups.

[0129] 2. Report Configuration: A list of report configurations, where each measurement object can have one or more report configurations. Each measurement report configuration contains at least one of the following:

[0130] • Reporting criteria: The criteria that trigger the terminal device to send a measurement report. This can be periodic or triggered based on a single event.

[0131] • Reference Signal (RS) type: including at least one of SSB; CSI-RS; SRS; TRS.

[0132] • Report Format: This includes at least one of the following: the form of the measurement report, the number of one or more antenna groups to be reported in the measurement report, the number of reference signal resource indications to be reported for each antenna group in the measurement report, the number of measurements to be reported for each antenna group in the measurement report, and the number of reference signals. Optionally, the form of the measurement report is as described in Forms 1 to 5 below, and will not be repeated here. Optionally, the report format can also be configured separately. For example, the number of reference signal resource indications and / or the number of measurements to be reported for each antenna group in the measurement report can be configured in the form of first configuration information. Another example is configuring the number of one or more antenna groups to be reported in the measurement report in the form of second configuration information. See step 420 below for a detailed description of the first configuration information. See step 520 below for a detailed description of the second configuration information. Optionally, the number of reference signals is indicated by the network device via CSI-ReportConfig.

[0133] 3. Measurement Identifiers: A list of measurement identifiers, each linking a measurement object to a report configuration. By configuring multiple measurement identifiers, multiple measurement objects can be linked to the same report configuration, or multiple report configurations can be linked to the same measurement object.

[0134] 4. Measurement Quantity Configuration: Used to indicate which measurement quantity(s) the terminal device should report. Optionally, the measurement quantity(s) include at least one of RSRP, SINR, Reference Signal Receiving Quality (RSRQ), and Received Signal Strength Indication (RSSI). Optionally, the measurement quantity configuration is indicated by the network device through the reportquantity in CSI-reportconfig.

[0135] 5. Measurement Interval: For connected NR UEs, a measurement interval needs to be configured on the network side when performing inter-frequency or inter-system measurements. Within the measurement interval, the UE stops all services and measurements. For intra-frequency measurements, the UE may also require a measurement interval, such as when the currently active Bandwidth Part (BWP) does not cover the SSB frequency to be measured. In terms of configuration, NR supports two measurement interval methods: measurement intervals based on the UE and measurement intervals based on the Frequency Range (FR).

[0136] In some embodiments, the measurement configuration is used to indicate one or more reference signal resources corresponding to N antenna groups. The reference signal resources indicate the resources used by the reference signals, including time-domain resources and / or frequency-domain resources and / or spatial-domain resources. The spatial-domain resources include the port index or number of ports corresponding to the reference signals. Alternatively, the measurement configuration can be understood as indicating one or more reference signals corresponding to each of the N antenna groups. That is, the measurement configuration is used to instruct the terminal device on which reference signal resources and / or reference signals to perform measurements.

[0137] In some embodiments, the reference signal resource includes at least one of the following:

[0138] • SSB resources;

[0139] • CSI-RS resources;

[0140] • SRS resources;

[0141] • TRS resources;

[0142] • Resources for reference signals used in beam management.

[0143] In some embodiments, one or more reference signal resources received by the terminal device belong to a set of reference signal resources or to multiple sets of reference signal resources.

[0144] In some embodiments, the network device configures only one set of reference signal resources to the terminal device. This set of reference signal resources includes one or more reference signal resources. These one or more reference signal resources correspond to the aforementioned N antenna groups.

[0145] In some embodiments, one or more reference signal resources belong to the same set of reference signal resources, which includes M reference signal resources. Each of the M reference signal resources belongs to one of N antenna groups, where M is a positive integer greater than or equal to N. Examples are shown in Table 2 below:

[0146] Table 2

[0147] Suppose the network device is configured with a reference signal resource set 1, which includes {reference signal resource 1, reference signal resource 2, reference signal resource 3, reference signal resource 4, reference signal resource 5, reference signal resource 6, and reference signal resource 7}. This reference signal resource set corresponds to 3 antenna groups.

[0148] In some embodiments, different antenna groups among the N antenna groups have the same number of reference signal resources. For example, antenna group 2 and antenna group 3, as shown in Table 2 above, each correspond to 2 reference signal resources.

[0149] In some embodiments, the number of reference signal resources corresponding to different antenna groups among the N antenna groups is different. For example, antenna group 1 and antenna group 2 shown in Table 2 above, antenna group 1 corresponds to 3 reference signal resources, and antenna group 2 corresponds to 2 reference signal resources.

[0150] In some embodiments, the network device configures multiple sets of reference signal resources for the terminal device. Each set of reference signal resources includes at least one reference signal resource.

[0151] In some embodiments, each of the multiple reference signal resource sets corresponds to one antenna group. In some embodiments, one or more reference signal resources belong to N reference signal resource sets, and the N reference signal resource sets correspond one-to-one with N antenna groups, where N is a positive integer. Examples are shown in Table 3 below:

[0152] Table 3

[0153] Suppose the network device is configured with three reference signal resource sets, namely {Reference Signal Resource Set 1, Reference Signal Resource Set 2, Reference Signal Resource Set 3}. Reference Signal Resource Set 1 includes {Reference Signal Resource 1, Reference Signal Resource 2, Reference Signal Resource 3}, Reference Signal Resource Set 2 includes {Reference Signal Resource 4, Reference Signal Resource 5}, and Reference Signal Resource Set 3 includes {Reference Signal Resource 6, Reference Signal Resource 7}. Reference Signal Resource Set 1 corresponds to antenna 1, Reference Signal Resource Set 2 corresponds to antenna 2, and Reference Signal Resource Set 3 corresponds to antenna 3.

[0154] In some embodiments, different reference signal resource sets within a plurality of reference signal resource sets correspond to the same number of reference signal resources. For example, reference signal resource set 2 and reference signal resource set 3, as shown in Table 3 above, each correspond to 2 reference signal resources.

[0155] In some embodiments, the number of reference signal resources corresponding to different reference signal resource sets in the plurality of reference signal resource sets is different. For example, in reference signal resource set 1 and reference signal resource set 2 shown in Table 3 above, antenna group 1 corresponds to 3 reference signal resources and antenna group 2 corresponds to 2 reference signal resources.

[0156] In some embodiments, each of the plurality of reference signal resource sets corresponds to one or more antenna groups. Examples are shown in Table 4 below:

[0157] Table 4

[0158] Suppose the network device is configured with two sets of reference signal resources, namely {Reference Signal Resource Set 1, Reference Signal Resource Set 2}. Reference Signal Resource Set 1 includes {Reference Signal Resource 1, Reference Signal Resource 2, Reference Signal Resource 3, Reference Signal Resource 4, Reference Signal Resource 5}, and Reference Signal Resource Set 2 includes {Reference Signal Resource 6, Reference Signal Resource 7}. Reference Signal Resource Set 1 corresponds to two antenna groups: Antenna 1 and Antenna 2, and Reference Signal Resource Set 2 corresponds to one antenna group: Antenna 3.

[0159] In some embodiments, when a set of reference signal resources corresponds to multiple antenna groups, different antenna groups correspond to different reference signal resources. The number of reference signal resources corresponding to different antenna groups can be the same or different. For example, as shown in Table 4 above, antenna group 1 corresponds to {reference signal resource 1, reference signal resource 2, reference signal resource 3}, while antenna group 2 corresponds to {reference signal resource 4, reference signal resource 5}.

[0160] In some embodiments, multiple sets of reference signal resources correspond to one antenna group. Examples are shown in Table 5 below:

[0161] Table 5

[0162] Suppose the network device is configured with two sets of reference signal resources, namely {Reference Signal Resource Set 1, Reference Signal Resource Set 2}. Reference Signal Resource Set 1 includes {Reference Signal Resource 1, Reference Signal Resource 2, Reference Signal Resource 3, Reference Signal Resource 4, Reference Signal Resource 5}, and Reference Signal Resource Set 2 includes {Reference Signal Resource 6, Reference Signal Resource 7}. Both Reference Signal Resource Set 1 and Reference Signal Resource Set 2 correspond to antenna 1.

[0163] In this embodiment, the example of a one-to-one correspondence between a set of reference signal resources and an antenna group is used for illustration.

[0164] It should be noted that step 320 described above can be implemented as a standalone embodiment. Alternatively, step 320 can be combined with step 220 described above to form an embodiment, with step 320 preceding step 220.

[0165] In summary, the method provided in this embodiment allows the terminal device to receive measurement configurations, thereby enabling it to perform measurements and report data accordingly, which helps ensure consistency in understanding between the terminal device and the network device.

[0166] In some embodiments, before reporting a measurement report, the terminal device also needs to determine the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report. Optionally, the terminal device determines the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report itself. For example, the terminal device determines, based on its own capabilities, that each antenna group corresponds to one reference signal resource indication and / or one measurement. Alternatively, the terminal device determines, based on its own capabilities, that each antenna group corresponds to multiple reference signal resource indications and / or multiple measurements.

[0167] In some embodiments, the terminal device determines the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report based on configuration information sent by the network device. For example, the terminal device determines the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report based on first configuration information sent by the network device. Optionally, the first configuration information is carried in the above-described measurement configuration. Optionally, the first configuration information and the above-described measurement configuration are two independent sets of configuration information.

[0168] In this embodiment, the first configuration information and the aforementioned measurement configuration are explained independently. As shown in Figure 6, the method further includes:

[0169] Step 420: The terminal device receives first configuration information, which is used to indicate a first quantity. The first quantity is the number of reference signal resources indicated and / or the number of measurements that each antenna group needs to report.

[0170] In some embodiments, the first configuration information is used to indicate that each antenna group needs to report a reference signal resource indication and / or a measurement; or, the first configuration information is used to indicate that each antenna group needs to report multiple reference signal resource indications and / or multiple measurements.

[0171] In some embodiments, the first quantity is less than or equal to a first quantity threshold, which is determined based on the capabilities of the terminal device. Alternatively, it can be understood as the first quantity being less than or equal to the maximum capability of the terminal device.

[0172] In some embodiments, the first configuration information is used to indicate the number of reference signal resource indications and / or the number of measurements that the r-th antenna group needs to report, where r is a positive integer.

[0173] For example, suppose the terminal device measures t reference signal resource indications and / or t measurement quantities corresponding to the r-th antenna group based on t reference signals. Then, the first configuration information is used to instruct the terminal device to select one or more reference signal resource indications from the t reference signal resource indications, and / or to select one or more measurement quantities from the t measurement quantities. The value of t is a positive integer.

[0174] In some embodiments, the first configuration information is carried in the higher-level signaling CSI reporting configuration CSI-ReportConfig.

[0175] In some embodiments, the reference signal resource indication includes one or more of the following: CRI; SSBRI.

[0176] In some embodiments, the measurement includes one or more of the following: L1-RSRP; L1-SINR; Layer 1 Reference Signal Receiving Quality (L1-RSRQ); and Layer 1 Received Signal Strength Indication (L1-RSSI).

[0177] It should be noted that in the embodiments of this application, the reference signal resource indications and the measured quantities are in one-to-one correspondence. For example, assuming that the reference signal resource indications to be reported by antenna group 1 include {reference signal resource indication 1, reference signal resource indication 2, reference signal resource indication 3}, then the measured quantities to be reported by antenna group 1 include {measurement quantity 1, measurement quantity 2, measurement quantity 3}. Or, assuming that the measured quantities to be reported by antenna group 1 include {measurement quantity 1, measurement quantity 2, measurement quantity 3}, then the reference signal resource indications to be reported by antenna group 1 include {reference signal resource indication 1, reference signal resource indication 2, reference signal resource indication 3}. Wherein, reference signal resource indication 1 corresponds to measurement quantity 1, reference signal resource indication 2 corresponds to measurement quantity 2, and reference signal resource indication 3 corresponds to measurement quantity 3.

[0178] In some embodiments, the size of each reference signal resource indication field is b1 bits, where b1 is a positive integer.

[0179] In some embodiments, the size of each measurement domain is b2 bits, where b2 is a positive integer.

[0180] For an introduction to CRI, SSBRI, L1-RSRP, or L1-SINR, please refer to the section on beam reporting in the relevant technologies mentioned above.

[0181] In summary, the method provided in this embodiment, in which the terminal device determines the first quantity by receiving the first configuration information, helps to ensure consistency in understanding between the terminal device and the network device.

[0182] It should be noted that step 420 can be implemented as a standalone embodiment. Alternatively, step 420 can be combined with step 220 in one embodiment, with step 420 preceding step 220. Alternatively, step 420 can be combined with step 320 in one embodiment, with steps 420 and 320 not having a specific order. Alternatively, step 420 can be combined with steps 220 and 320 in one embodiment, with steps 420 and 320 preceding step 220, but the order of steps 420 and 320 is not important.

[0183] In some embodiments, before reporting a measurement report, the terminal device also needs to determine which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to.

[0184] In some embodiments, the terminal device determines which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to. For example, the terminal device determines, based on its own capabilities, that the one or more antenna groups corresponding to the measurement report are all of the N antenna groups. Alternatively, the terminal device determines, based on its own capabilities, that the one or more antenna groups corresponding to the measurement report are only a portion of the N antenna groups.

[0185] In some embodiments, the terminal device determines which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to based on configuration information sent by the network device. For example, the terminal device determines the one or more antenna groups corresponding to the measurement report based on second configuration information sent by the network device. Optionally, the second configuration information is carried in the above-described measurement configuration. Optionally, the second configuration information and the above-described measurement configuration are two independent sets of configuration information.

[0186] In this embodiment, the second configuration information and the aforementioned measurement configuration are explained independently. As shown in Figure 7, the method further includes:

[0187] Step 520: The terminal device receives second configuration information, which is used to indicate one or more antenna groups.

[0188] In some embodiments, the second configuration information is used to instruct the terminal device to report measurement information corresponding to all antenna groups in the N antenna groups.

[0189] In some embodiments, the second configuration information is used to indicate that the terminal device needs to report measurement information corresponding to a portion of the N antenna groups.

[0190] For example, assuming N antenna groups include {antenna group 1, antenna group 2, antenna group 3}, the second configuration information is used to instruct the terminal device to report the measurement information corresponding to all 3 antenna groups, or the second configuration information is used to instruct the reporting of the measurement information corresponding to some of the 3 antenna groups, such as reporting the measurement information corresponding to {antenna group 1, antenna group 2}.

[0191] In some embodiments, the second configuration information carries a first antenna group index, which indicates the antenna group for which the terminal device needs to report corresponding measurement information. For example, assume N antenna groups include {antenna group 1, antenna group 2, antenna group 3}. Antenna group 1 corresponds to antenna group index 1, antenna group 2 corresponds to antenna group index 2, and antenna group 3 corresponds to antenna group index 3. If the first antenna group index includes {antenna group index 1, antenna group index 2}, it indicates that the terminal device needs to report the measurement information corresponding to antenna group 1 and antenna group 2.

[0192] In some embodiments, the second configuration information is carried in the higher-level signaling CSI reporting configuration CSI-ReportConfig.

[0193] In summary, the method provided in this embodiment allows the terminal device to determine which antenna groups' measurement information needs to be reported by receiving the first configuration information, which helps ensure consistency in understanding between the terminal device and the network device.

[0194] It should be noted that step 520 can be implemented as a standalone embodiment. Alternatively, step 520 can be combined with step 220 in one embodiment, with step 520 preceding step 220. Alternatively, step 520 can be combined with step 320 in one embodiment, with steps 520 and 320 not having a specific order. Alternatively, step 520 can be combined with step 420 in one embodiment, with steps 520 and 420 not having a specific order. Alternatively, step 520 can be combined with steps 220 and 320 in one embodiment, with steps 520 and 320 preceding step 220, but steps 520 and 320 not having a specific order. Alternatively, step 520 can be combined with steps 220 and 420 in one embodiment, with steps 520 and 420 preceding step 220, but steps 520 and 420 not having a specific order. Alternatively, step 520 can be combined with steps 320 and 420 to form one embodiment, and steps 520, 320, and 420 can be implemented in any order. Alternatively, step 520 can be combined with steps 220, 320, and 420 to form one embodiment, and steps 520, 420, and 320 precede step 220, but steps 520, 320, and 420 can be implemented in any order.

[0195] Next, we will introduce the measurement report in detail:

[0196] In some embodiments, the terminal device reports measurement reports corresponding to all antenna groups out of N antenna groups. The measurement reports include measurement results for all antenna groups, and the measurement results for each antenna group include one or more reference signal resource indications and / or one or more measured quantities. For example, as shown in Figure 8, assuming the network device's antenna array is divided into 4 antenna groups {antenna group 1, antenna group 2, antenna group 3, antenna group 4}, the terminal device will report measurement reports corresponding to all 4 antenna groups. Alternatively, the measurement reports can be understood as including the measurement results corresponding to all 4 antenna groups.

[0197] In some embodiments, the terminal device reports measurement reports corresponding to a portion of N antenna groups. The measurement reports include measurement results for a portion of the N antenna groups, and the measurement results for each antenna group include one or more reference signal resource indications and / or one or more measurements. For example, as shown in Figure 9, assuming the network device's antenna array is divided into four antenna groups {antenna group 1, antenna group 2, antenna group 3, antenna group 4}, the terminal device will report measurement reports corresponding to {antenna group 3, antenna group 4}. Alternatively, the measurement reports include the measurement results corresponding to {antenna group 3, antenna group 4}, but not the measurement results corresponding to {antenna group 1, antenna group 2}. Reporting measurement information for a portion of the antenna groups by the terminal device can solve the problem that some antenna ports of the network device's antenna array are invisible to the terminal device due to spatial non-stationarity. That is, the terminal device only needs to report the beam measurement results corresponding to the visible portion of the antenna groups, which also reduces the complexity of beam reporting.

[0198] It should be noted that the difference between reporting measurement reports for all antenna groups out of N antenna groups and reporting measurement reports for only a portion of the N antenna groups lies in the number of antenna groups corresponding to the measurement reports. In this embodiment, the measurement report corresponds to W antenna groups out of N antenna groups as an example, where W is a positive integer less than or equal to N.

[0199] In some embodiments, measurement reports may include various forms, as shown below:

[0200] Format 1:

[0201] In some embodiments, the measurement report includes one or more of the following:

[0202] • One or more reference signal resource indicators for each antenna group;

[0203] • One or more measurement quantities corresponding to each antenna group;

[0204] • Antenna group index, used to indicate one or more antenna groups;

[0205] • Reference signal resource set index, used to indicate one or more reference signal resource sets.

[0206] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report includes one or more of the following:

[0207] • A reference signal resource indication corresponding to the first antenna group, up to a reference signal resource indication corresponding to the Wth antenna group;

[0208] • A measurement quantity corresponding to the first antenna group, up to a measurement quantity corresponding to the Wth antenna group;

[0209] • Antenna group index, used to indicate W antenna groups;

[0210] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0211] It should be noted that the reference signal resource indication corresponding to the x-th antenna group carried in the measurement report corresponds to a measurement quantity corresponding to the x-th antenna group.

[0212] In some embodiments, where the measurement report includes only one reference signal resource indication for each antenna group, the reference signal resource indication can be any one of one or more reference signal resource indications for each antenna group. For example, assuming antenna group 1 corresponds to 3 reference signal resource indications {reference signal resource indication 1, reference signal resource indication 2, reference signal resource indication 3}, the measurement report can carry any one of {reference signal resource indication 1, reference signal resource indication 2, reference signal resource indication 3}.

[0213] In some embodiments, where the measurement report includes only one measurement corresponding to each antenna group, that measurement can be any one of one or more measurements corresponding to each antenna group. For example, assuming antenna group 1 corresponds to 3 measurements {measurement 1, measurement 2, measurement 3}, the measurement report can carry any one of {measurement 1, measurement 2, measurement 3}.

[0214] In some embodiments, where the measurement report includes only one reference signal resource indication for each antenna group, this reference signal resource indication can be the one among one or more reference signal resource indications for each antenna group that corresponds to the minimum value of one or more measured quantities. For example, suppose antenna group 1 corresponds to 3 measured quantities {measurement quantity 1, measurement quantity 2, measurement quantity 3}, where measurement quantity 1 is less than measurement quantity 2, and measurement quantity 2 is less than measurement quantity 3. Then the measurement report carries the reference signal resource indication corresponding to measurement quantity 1.

[0215] In some embodiments, when the measurement report includes only one reference signal resource indication for each antenna group, this reference signal resource indication may be one of the one or more reference signal resource indications for each antenna group that corresponds to the median value of one or more measured quantities. For example, suppose antenna group 1 corresponds to 3 measured quantities {measurement quantity 1, measurement quantity 2, measurement quantity 3}, where measurement quantity 1 is less than measurement quantity 2, and measurement quantity 2 is less than measurement quantity 3. Then the measurement report carries the reference signal resource indication corresponding to measurement quantity 2.

[0216] In some embodiments, where the measurement report includes only one reference signal resource indication for each antenna group, this reference signal resource indication may be the one among one or more reference signal resource indications for each antenna group that corresponds to the maximum value of one or more measured quantities. Where measured quantity 1 is less than measured quantity 2, and measured quantity 2 is less than measured quantity 3, then the measurement report carries the reference signal resource indication corresponding to measured quantity 3.

[0217] In some embodiments, when the measurement report includes only one measurement for each antenna group, that measurement can be the minimum value among one or more measurements for each antenna group. For example, suppose antenna group 1 corresponds to 3 measurements {measurement 1, measurement 2, measurement 3}, where measurement 1 is less than measurement 2, and measurement 2 is less than measurement 3. Then the measurement report carries measurement 1.

[0218] In some embodiments, where the measurement report includes only one measurement for each antenna group, that measurement can be an intermediate value among one or more measurements for each antenna group. For example, suppose antenna group 1 corresponds to three measurements {measurement 1, measurement 2, measurement 3}, where measurement 1 is less than measurement 2, and measurement 2 is less than measurement 3. Then the measurement report would carry measurement 2.

[0219] In some embodiments, where the measurement report includes only one measurement for each antenna group, that measurement can be the maximum value among one or more measurements for each antenna group. For example, suppose antenna group 1 corresponds to 3 measurements {measurement 1, measurement 2, measurement 3}, where measurement 1 is less than measurement 2, and measurement 2 is less than measurement 3. Then the measurement report would include measurement 3.

[0220] For example, the measurement report is shown in Table 6 below:

[0221] Table 6

[0222] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report includes one or more of the following:

[0223] • Multiple reference signal resource indications corresponding to the first antenna group, up to the multiple reference signal resource indications corresponding to the Wth antenna group;

[0224] • Multiple measurements corresponding to the first antenna group, up to the multiple measurements corresponding to the Wth antenna group;

[0225] • Antenna group index, used to indicate W antenna groups;

[0226] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0227] In some embodiments, where the measurement report includes multiple reference signal resource indications and / or multiple measurements corresponding to each antenna group, the multiple reference signal resource indications correspond one-to-one with the multiple measurements.

[0228] For example, the measurement report is shown in Table 7 below:

[0229] Table 7

[0230] In some embodiments, the measurement report may not include the antenna group index and / or reference signal resource set index. For example, when the measurement report corresponds to all antenna groups out of W antenna groups, the terminal device can report the measurement report in ascending order of antenna group index. Since the reference signal resource indication and / or measurement quantity corresponding to each antenna group will be reported, the measurement report is reported according to the number of bits occupied by each information field in the order of the antenna group index. Alternatively, the measurement report can be reported in ascending order of the reference signal resource set index. Since the reference signal resource indication and / or measurement quantity corresponding to each reference signal resource set will be reported, the measurement report is reported according to the number of bits occupied by each information field in the order of the reference signal resource set index.

[0231] For example, in the case where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report is shown in Table 8 below:

[0232] Table 8

[0233] For example, in the case where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report is shown in Table 9 below:

[0234] Table 9

[0235] In some embodiments, the measurement report may not include the antenna group index and / or reference signal resource set index. For example, the terminal device reports a first bitmap to the network device to inform the network device which of the N antenna groups the measurement report corresponds to. As shown in Figure 10, the above method further includes:

[0236] Step 620: The terminal device reports the first bit map, which is used to indicate one or more antenna groups among the N antenna groups.

[0237] In some embodiments, the first bitmap corresponds to N bits.

[0238] In some embodiments, when the p-th bit in the first bit diagram is a first value, it indicates that the measurement report includes measurement information of the antenna group corresponding to the p-th bit; when the q-th bit in the first bit diagram is a second value, it indicates that the measurement report does not include measurement information of the antenna group corresponding to the p-th bit. Here, p is a positive integer and q is a positive integer.

[0239] For example, when the p-th bit in the first bit diagram is 0, it is used to indicate that the measurement report includes the measurement information of the antenna group corresponding to the p-th bit; when the q-th bit in the first bit diagram is 1, it is used to indicate that the measurement report does not include the measurement information of the antenna group corresponding to the p-th bit.

[0240] For example, when the p-th bit in the first bit diagram is 1, it is used to indicate that the measurement report includes the measurement information of the antenna group corresponding to the p-th bit; when the q-th bit in the first bit diagram is 0, it is used to indicate that the measurement report does not include the measurement information of the antenna group corresponding to the p-th bit.

[0241] For example, suppose N is 4, meaning the network device's antenna array is divided into 4 antenna groups {antenna group 1, antenna group 2, antenna group 3, antenna group 4}. Assuming the first bitmap is {1110}, the first bitmap is used to indicate that the measurement report includes measurement information corresponding to {antenna group 1, antenna group 2, antenna group 3}, but does not include measurement information corresponding to {antenna group 4}.

[0242] In some embodiments, the first bitmap is carried in the measurement report; or, the first bitmap and the measurement report are independent of each other.

[0243] It should be noted that when the first bitmap is included in the measurement report, steps 620 and 220 above are actually one step. When the first bitmap and the measurement report are independent of each other, the first bitmap can accurately indicate which of the N antenna groups the one or more antenna groups corresponding to the measurement report are.

[0244] Step 620 described above can be implemented as a single embodiment. Alternatively, step 620 can be combined with step 220 to form an embodiment, with step 620 preceding step 220. Alternatively, step 620 can be combined with step 320 to form an embodiment, with steps 620 and 320 not having a specific order.

[0245] By reporting measurement reports corresponding to Form 1, the terminal device can achieve beam reporting based on antenna groups. Since the channel between each antenna group and the terminal device can be approximated as a far-field channel, reporting measurement reports that include measurement information for each antenna group helps reduce the complexity of beam reporting. Furthermore, the terminal device may only report measurement information corresponding to a portion of the antenna groups, which can address the issue that some antenna ports of the network device's antenna array are invisible to the terminal device due to spatial non-stationarity. That is, the terminal device only needs to report the beam measurement information corresponding to the visible portion of the antenna groups.

[0246] Form Two:

[0247] In some embodiments, the measurement report includes one or more of the following:

[0248] • One or more reference signal resource indicators for each antenna group;

[0249] • The first maximum value corresponding to each antenna group, where the first maximum value corresponding to the i-th antenna group is the maximum value among all the measurements corresponding to the i-th antenna group;

[0250] • For each antenna group, there are one or more first difference values. The j-th first difference value among the one or more first difference values ​​corresponding to the i-th antenna group is the difference between the j-th measurement quantity corresponding to the i-th antenna group and the first maximum value corresponding to the i-th antenna group.

[0251] • Antenna group index, used to indicate one or more antenna groups;

[0252] • Reference signal resource set index, used to indicate one or more reference signal resource sets;

[0253] Where i is a positive integer and j is a positive integer.

[0254] It should be noted that the difference between Form 2 and Form 1 is that the measurement report must include at least the first maximum value corresponding to each antenna group and / or the reference signal resource indication corresponding to the first maximum value.

[0255] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report includes one or more of the following:

[0256] • A reference signal resource indication corresponding to the first antenna group, up to a reference signal resource indication corresponding to the Wth antenna group;

[0257] • The first maximum value corresponding to the first antenna group, up to the first maximum value corresponding to the Wth antenna group;

[0258] • Antenna group index, used to indicate W antenna groups;

[0259] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0260] In some embodiments, when the measurement report includes only one reference signal resource indication corresponding to each antenna group, the reference signal resource indication is the one among one or more reference signal resource indications corresponding to each antenna group that corresponds to a first maximum value. For example, suppose antenna group 1 corresponds to 3 measurements {measurement 1, measurement 2, measurement 3}, where measurement 1 is less than measurement 2, and measurement 2 is less than measurement 3. Then the first maximum value corresponding to antenna group 1 is measurement 3, that is, the measurement report carries measurement 3 and / or carries a reference signal resource indication corresponding to measurement 3.

[0261] For example, the measurement report is shown in Table 10 below:

[0262] Table 10

[0263] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report includes one or more of the following:

[0264] • Multiple reference signal resource indications corresponding to the first antenna group, up to the multiple reference signal resource indications corresponding to the Wth antenna group;

[0265] • The first maximum value corresponding to the first antenna group, up to the first maximum value corresponding to the Wth antenna group;

[0266] • One or more first differential values ​​corresponding to the first antenna group, up to one or more first differential values ​​corresponding to the Wth antenna group;

[0267] • Antenna group index, used to indicate W antenna groups;

[0268] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0269] In some embodiments, the number of reference signal resource indications corresponding to each antenna group is consistent with the total number of first maximum values ​​and one or more first differential values ​​corresponding to each antenna group. For example, assuming antenna group 1 corresponds to 3 reference signal resource indications, the measurement report may also carry the first maximum value and 2 first differential values ​​corresponding to antenna group 1. The 2 first differential values ​​are determined based on 2 measurements other than the first maximum value corresponding to antenna group 1. For example, assuming antenna group 1 corresponds to 3 measurements {measurement 1, measurement 2, measurement 3}, where measurement 1 is less than measurement 2, and measurement 2 is less than measurement 3, then the first maximum value corresponding to antenna group 1 is measurement 3. The measurement report may also carry the first differential value 1 and the first differential value 2 corresponding to antenna group 1, where the first differential value 1 is equal to the difference between measurement 1 and measurement 3, and the first differential value 2 is equal to the difference between measurement 2 and measurement 3.

[0270] For example, the measurement report is shown in Table 11 below:

[0271] Table 11

[0272] The first differential value corresponding to the first antenna group is determined based on the first measured quantity and the first maximum value corresponding to the first antenna group. For example, the first differential value corresponding to the first antenna group = the first measured quantity - the first maximum value. Or, the first differential value corresponding to the first antenna group = the first maximum value - the first measured quantity. This continues until the Wth antenna group.

[0273] In some embodiments, the measurement report may omit the antenna group index and / or reference signal resource set index. Refer to the description corresponding to the above-described form.

[0274] For example, in the case where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report is shown in Table 12 below:

[0275] Table 12

[0276] For example, in the case where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report is shown in Table 13 below:

[0277] Table 13

[0278] In some embodiments, if the measurement report does not carry an antenna group index and / or a reference signal resource set index, the terminal device can report a first bitmap to the network device to inform the network device which of the N antenna groups the W antenna groups corresponding to the measurement report are. See step 620 above for details.

[0279] It should be noted that in this embodiment of the application, the reporting of the difference value adopts a quantitative method.

[0280] By reporting the measurement report corresponding to Form 2, the amount of data required for the measurement report can be reduced. The terminal device only needs to report the maximum measurement value corresponding to each antenna group, and other measurement values ​​can be reported using the first difference value. The amount of data corresponding to the measurement report corresponding to Form 2 is: the amount of data corresponding to W first maximum values ​​+ the amount of data corresponding to multiple first difference values.

[0281] Form 3:

[0282] In some embodiments, the measurement report includes one or more of the following:

[0283] • One or more reference signal resource indicators for each antenna group;

[0284] • The second maximum value is the maximum value among all the measurements corresponding to one or more antenna groups, and the second maximum value corresponds to the first antenna group;

[0285] • First antenna group index, used to indicate the first antenna group;

[0286] • One or more second difference values, wherein the a-th second difference value among the one or more second difference values ​​is the difference between the a-th measurement and the second maximum value, and the a-th measurement is a measurement information other than the second maximum value among the one or more measurement values ​​corresponding to each antenna group;

[0287] • Second antenna group index, used to indicate the second antenna group, which is one or more antenna groups other than the first antenna group;

[0288] • Reference signal resource set index, used to indicate one or more reference signal resource sets;

[0289] Where 'a' takes the value of a positive integer.

[0290] It should be noted that the difference between Form 3 and Form 2 is that Form 3 includes only one second maximum value for all W antenna groups, while Form 2 includes W first maximum values ​​for all W antenna groups.

[0291] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report includes one or more of the following:

[0292] • A reference signal resource indication corresponding to the first antenna group, up to a reference signal resource indication corresponding to the Wth antenna group;

[0293] • The second maximum value is the maximum value among all the measurements corresponding to the W antenna groups. The second maximum value corresponds to the Kth antenna group among the W antenna groups.

[0294] • First antenna group index, used to indicate the Kth antenna group;

[0295] • A second difference value corresponding to the second antenna group, which is the other antenna groups among the W antenna groups except for the Kth antenna group;

[0296] • The second day's line group index is used to indicate the second day's line group;

[0297] • Reference signal resource set index, used to indicate N reference signal resource sets;

[0298] Where K is a positive integer less than or equal to W.

[0299] For example, the measurement report is shown in Table 14 below:

[0300] Table 14

[0301] The second differential value corresponding to the first antenna group is determined based on the difference between the measured quantity corresponding to the first antenna group and the second maximum value corresponding to the Kth antenna group. For example, the second differential value corresponding to the first antenna group = the measured quantity corresponding to the first antenna group - the second maximum value corresponding to the Kth antenna group. Or, the second differential value corresponding to the first antenna group = the second maximum value corresponding to the Kth antenna group - the measured quantity corresponding to the first antenna group. And so on, up to the Wth antenna group.

[0302] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report includes one or more of the following:

[0303] • Multiple reference signal resource indications corresponding to the first antenna group, up to the multiple reference signal resource indications corresponding to the Wth antenna group;

[0304] • The second maximum value is the maximum value among all the measurements corresponding to the W antenna groups. The second maximum value corresponds to the Kth antenna group among the W antenna groups.

[0305] • First antenna group index, used to indicate the Kth antenna group;

[0306] • One or more second differential values ​​corresponding to the first antenna group, up to one or more second differential values ​​corresponding to the Wth antenna group;

[0307] • Second antenna group index, used to indicate the second antenna group, which is the other antenna group among the W antenna groups except the Kth antenna group;

[0308] • Reference signal resource set index, used to indicate W reference signal resource sets;

[0309] Where K is a positive integer less than or equal to W.

[0310] For example, the measurement report is shown in Table 15 below:

[0311] Table 15

[0312] The first second differential value corresponding to the first antenna group is determined based on the first measurement value corresponding to the first antenna group and the second maximum value corresponding to the Kth antenna group. For example, the first second differential value corresponding to the first antenna group = the first measurement value corresponding to the first antenna group - the second maximum value corresponding to the Kth antenna group. Or, the first second differential value corresponding to the first antenna group = the second maximum value corresponding to the Kth antenna group - the first measurement value corresponding to the first antenna group. And so on, up to the Wth antenna group.

[0313] In some embodiments, the measurement report may omit the antenna group index and / or reference signal resource set index. Refer to the description corresponding to the above-described form.

[0314] For example, in the case where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report is shown in Table 16 below:

[0315] Table 16

[0316] For example, in the case where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report is shown in Table 17 below:

[0317] Table 17

[0318] In some embodiments, if the measurement report does not carry an antenna group index and / or a reference signal resource set index, the terminal device can report a first bitmap to the network device to inform the network device which of the N antenna groups the W antenna groups corresponding to the measurement report are. See step 620 above for details.

[0319] It should be noted that in the embodiments of this application, the measurement quantity corresponding to any second difference value is less than the second maximum value.

[0320] By reporting the measurement report corresponding to Form 3, the amount of data required for the measurement report can be further reduced compared to Form 2. The terminal device only needs to report the maximum measurement quantity corresponding to one antenna group, and other measurement quantities are reported using the second differential value method. The amount of data corresponding to the measurement report corresponding to Form 3 is: the amount of data corresponding to one second maximum value + the amount of data corresponding to multiple second differential values.

[0321] Form Four:

[0322] In some embodiments, the measurement report includes one or more of the following:

[0323] • One or more reference signal resource indicators for each antenna group;

[0324] • The third maximum value is the maximum value among all the measurements corresponding to the third antenna group. The third antenna group is the antenna group with the smallest index value.

[0325] • One or more third difference values, wherein the b-th third difference value among the one or more third difference values ​​is the difference between the b-th measurement and the third maximum value, and the b-th measurement is a measurement information other than the third maximum value among the one or more measurement values ​​corresponding to each antenna group;

[0326] • Antenna group index, used to indicate one or more antenna groups;

[0327] • Reference signal resource set index, used to indicate one or more reference signal resource sets;

[0328] Where b takes the value of a positive integer.

[0329] It should be noted that the difference between Form 4 and Form 2 is that Form 4 includes only one third maximum value for all W antenna groups, while Form 2 includes W first maximum values ​​for all W antenna groups. Furthermore, the difference between Form 4 and Form 3 is that the third maximum value in Form 4 corresponds to the antenna group with the smallest index value, while the second maximum value in Form 3 corresponds to the first antenna group, which is determined based on the maximum value among all measurements corresponding to the W antenna groups.

[0330] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report includes one or more of the following:

[0333] • A third differential value corresponding to the fifth antenna group, which is the other antenna group among the W antenna groups besides the third antenna group;

[0334] • Antenna group index, used to indicate W antenna groups;

[0335] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0336] For example, the measurement report is shown in Table 18 below:

[0337] Table 18

[0338] The third differential value corresponding to the second antenna group is determined based on the measured quantity of the second antenna group and the third maximum value of the first antenna group. For example, the third differential value corresponding to the second antenna group = the measured quantity of the second antenna group - the third maximum value of the first antenna group. Or, the third differential value corresponding to the second antenna group = the third maximum value of the first antenna group - the measured quantity of the second antenna group. And so on, until the Wth antenna group.

[0339] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report includes one or more of the following:

[0340] • Multiple reference signal resource indications corresponding to the first antenna group, up to the multiple reference signal resource indications corresponding to the Wth antenna group;

[0341] • The third maximum value is the maximum value among all the measurements corresponding to the third antenna group. The third antenna group is the antenna group with the smallest index value.

[0342] • One or more third differential values ​​corresponding to the first antenna group, up to one or more third differential values ​​corresponding to the Wth antenna group;

[0343] • Antenna group index, used to indicate W antenna groups;

[0344] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0345] For example, the measurement report is shown in Table 19 below:

[0346] Table 19

[0347] The first third differential value corresponding to the first antenna group is determined based on the first measured quantity and the third maximum value corresponding to the first antenna group. For example, the first third differential value corresponding to the first antenna group = the first measured quantity - the third maximum value. Or, the first third differential value corresponding to the first antenna group = the third maximum value - the first measured quantity. This continues until the Wth antenna group.

[0348] In some embodiments, the measurement report may omit the antenna group index and / or reference signal resource set index. Refer to the description corresponding to the above-described form.

[0349] For example, in the case where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report is shown in Table 20 below:

[0350] Table 20

[0351] For example, in the case where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report is shown in Table 21 below:

[0352] Table 21

[0353] In some embodiments, if the measurement report does not carry an antenna group index and / or a reference signal resource set index, the terminal device can report a first bitmap to the network device to inform the network device which of the N antenna groups the W antenna groups corresponding to the measurement report are. See step 620 above for details.

[0354] It should be noted that in the embodiments of this application, the measurement quantity corresponding to any third difference value may be greater than the third maximum value or less than the third maximum value.

[0355] By reporting the measurement report corresponding to Form 4, the amount of data required for the measurement report can be further reduced compared to Form 2. The terminal device only needs to report the maximum measurement quantity corresponding to one antenna group, and other measurement quantities are reported using the third differential value method. The amount of data corresponding to the measurement report corresponding to Form 4 is: the amount of data corresponding to one third maximum value + the amount of data corresponding to multiple third differential values.

[0356] Form 5:

[0357] In some embodiments, the measurement report includes one or more of the following:

[0358] • One or more reference signal resource indicators for each antenna group;

[0359] • The fourth maximum value is the maximum value among all the measurements corresponding to the fourth antenna group. The fourth antenna group is the antenna group with the largest index value.

[0360] • One or more fourth difference values, wherein the c-th fourth difference value among the one or more fourth difference values ​​is the difference between the c-th measurement and the fourth maximum value, and the c-th measurement is a measurement information other than the third maximum value among the one or more measurements corresponding to each antenna group;

[0361] • Antenna group index, used to indicate one or more antenna groups;

[0362] • Reference signal resource set index, used to indicate one or more reference signal resource sets;

[0363] Where c takes the value of a positive integer.

[0364] It should be noted that the difference between Form 4 and Form 2 is that Form 5 includes only one fourth maximum value for all W antenna groups, while Form 2 includes W first maximum values ​​for all W antenna groups. Furthermore, the difference between Form 5 and Form 3 is that the fourth maximum value in Form 5 corresponds to the antenna group with the largest index value, while the second maximum value in Form 3 corresponds to the first antenna group, which is determined based on the maximum value among all measurements corresponding to the W antenna groups. Finally, the difference between Form 5 and Form 4 is that the fourth maximum value in Form 5 corresponds to the antenna group with the largest index value, while the third maximum value in Form 4 corresponds to the antenna group with the smallest index value.

[0365] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report includes one or more of the following:

[0366] • A reference signal resource indication corresponding to the first antenna group, up to a reference signal resource indication corresponding to the Wth antenna group;

[0367] • The fourth maximum value is the maximum value among all the measurements corresponding to the fourth antenna group. The fourth antenna group is the antenna group with the largest index value.

[0368] • A fourth differential value corresponding to the sixth antenna group, which is the other antenna group among the W antenna groups besides the fourth antenna group;

[0369] • Antenna group index, used to indicate W antenna groups;

[0370] • Reference signal resource set index, used to indicate W reference signal resource sets.

[0371] For example, the measurement report is shown in Table 22 below:

[0372] Table 22

[0373] The fourth differential value corresponding to the first antenna group is determined based on the measured quantity corresponding to the first antenna group and the fourth maximum value corresponding to the Wth antenna group. For example, the fourth differential value corresponding to the first antenna group = the measured quantity corresponding to the first antenna group - the fourth maximum value corresponding to the Wth antenna group. Or, the fourth differential value corresponding to the first antenna group = the fourth maximum value corresponding to the Wth antenna group - the measured quantity corresponding to the first antenna group. And so on, up to the (W-1)th antenna group.

[0374] In some embodiments, where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report includes one or more of the following:

[0378] • Antenna group index, used to indicate W antenna groups;

[0380] For example, the measurement report is shown in Table 23 below:

[0381] Table 23

[0382] The first fourth differential value corresponding to the first antenna group is determined based on the first measurement of the first antenna group and the fourth maximum value corresponding to the Wth antenna group. For example, the first fourth differential value corresponding to the first antenna group = the first measurement of the first antenna group - the fourth maximum value corresponding to the Wth antenna group. Or, the first fourth differential value corresponding to the first antenna group = the fourth maximum value corresponding to the Wth antenna group - the first measurement of the first antenna group. And so on, up to the Wth antenna group.

[0383] In some embodiments, the measurement report may omit the antenna group index and / or reference signal resource set index. Refer to the description corresponding to the above-described form.

[0384] For example, in the case where the first configuration information described above is used to instruct each antenna group to report a reference signal resource indication and / or a measurement, the measurement report is shown in Table 24 below:

[0385] Table 24

[0386] For example, in the case where the first configuration information described above is used to instruct each antenna group to report multiple reference signal resource indications and / or multiple measurements, the measurement report is shown in Table 25 below:

[0387] Table 25

[0388] In some embodiments, if the measurement report does not carry an antenna group index and / or a reference signal resource set index, the terminal device can report a first bitmap to the network device to inform the network device which of the N antenna groups the W antenna groups corresponding to the measurement report are. See step 620 above for details.

[0389] It should be noted that in the embodiments of this application, the measurement quantity corresponding to any fourth difference value may be greater than the fourth maximum value or less than the fourth maximum value.

[0390] By reporting the measurement report corresponding to Form 5, the amount of data required for the measurement report can be further reduced compared to Form 2. The terminal device only needs to report the maximum measurement quantity corresponding to one antenna group, and other measurement quantities are reported using the fourth differential value method. The amount of data corresponding to the measurement report corresponding to Form 5 is: the amount of data corresponding to one fourth maximum value + the amount of data corresponding to multiple fourth differential values.

[0391] It should also be noted that the measurement report may also correspond to other forms, and the embodiments of this application do not exclude the possibility that the terminal device may also report the measurement report in other forms.

[0392] In some embodiments, this application provides a flowchart of a sending and receiving method. As shown in FIG11, the method is executed by a terminal device, and the method includes:

[0393] Step 11: The terminal device receives the network configuration;

[0394] In some embodiments, network configuration includes at least one of measurement configuration, first configuration information, and second configuration information.

[0395] In some embodiments, the terminal device receives measurement configuration. See step 320 above for detailed implementation.

[0396] In some embodiments, the first configuration information is carried in the measurement configuration. In some embodiments, the first configuration information is independent of the measurement configuration, and the terminal device receives the first configuration information. For detailed implementation, see step 420 above.

[0397] In some embodiments, the second configuration information is carried in the measurement configuration. In some embodiments, the second configuration information is independent of the measurement configuration, and the terminal device receives the second configuration information. For detailed implementation, see step 520 above.

[0398] Step 12: The terminal device performs the measurement;

[0399] In some embodiments, the terminal device receives one or more reference signals and measures N antenna groups based on the received reference signals.

[0400] Step 13: The terminal device reports the measurement report.

[0401] For detailed implementation instructions, please refer to step 220 above, as well as the detailed description in the measurement report section.

[0402] In some embodiments, this application provides a method for receiving a measurement report. As shown in FIG12, the method is performed by a network device and includes:

[0403] Step 720: The network device receives a measurement report, which indicates the measurement results corresponding to one or more antenna groups.

[0404] In some embodiments, step 720 corresponds to reporting step 220. That is, the measurement report received by the network device refers to the measurement report reported by the terminal device.

[0405] In some embodiments, before reporting a measurement report, the terminal device needs to receive the measurement configuration from the network device and then perform the measurement according to the instructions in the measurement configuration. That is, the network device needs to send the measurement configuration to the terminal device in advance. As shown in Figure 13, the above method further includes:

[0406] Step 820: The network device sends a measurement configuration, which indicates one or more reference signal resources corresponding to the N antenna groups.

[0407] In some embodiments, step 820 corresponds to reporting step 320. It should be noted that step 820 can be implemented as a separate embodiment. Alternatively, step 820 can be combined with step 720 as a single embodiment, with step 820 preceding step 720.

[0408] In some embodiments, before reporting a measurement report, the terminal device also needs to determine the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report. Optionally, the terminal device determines the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report itself. For example, the terminal device determines, based on its own capabilities, that each antenna group corresponds to one reference signal resource indication and / or one measurement. Alternatively, the terminal device determines, based on its own capabilities, that each antenna group corresponds to multiple reference signal resource indications and / or multiple measurements.

[0409] In some embodiments, the terminal device determines the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report based on configuration information sent by the network device. For example, the terminal device determines the number of reference signal resource indications and / or the number of measurements corresponding to each antenna group carried in the measurement report based on first configuration information sent by the network device. Optionally, the first configuration information is carried in the above-described measurement configuration. Optionally, the first configuration information and the above-described measurement configuration are two independent sets of configuration information.

[0410] In this embodiment, the first configuration information and the aforementioned measurement configuration are explained independently of each other. As shown in Figure 14, the method further includes:

[0411] Step 920: The network device sends first configuration information, which is used to indicate a first quantity, which is the number of reference signal resources indicated and / or the number of measurements that each antenna group needs to report.

[0412] In some embodiments, step 920 corresponds to reporting step 420. That is, the network device sends the first configuration information to the terminal device.

[0413] It should be noted that step 920 can be implemented as a standalone embodiment. Alternatively, step 920 can be combined with step 720 in one embodiment, with step 920 preceding step 720. Alternatively, step 920 can be combined with step 820 in one embodiment, with steps 920 and 820 not having a specific order. Alternatively, step 920 can be combined with steps 720 and 820 in one embodiment, with steps 920 and 820 preceding step 720, but steps 920 and 820 not having a specific order.

[0414] In some embodiments, before reporting a measurement report, the terminal device also needs to determine which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to.

[0415] In some embodiments, the terminal device determines which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to. For example, the terminal device determines, based on its own capabilities, that the one or more antenna groups corresponding to the measurement report are all of the N antenna groups. Alternatively, the terminal device determines, based on its own capabilities, that the one or more antenna groups corresponding to the measurement report are only a portion of the N antenna groups.

[0416] In some embodiments, the terminal device determines which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to based on configuration information sent by the network device. For example, the terminal device determines the one or more antenna groups corresponding to the measurement report based on second configuration information sent by the network device. Optionally, the second configuration information is carried in the above-described measurement configuration. Optionally, the second configuration information and the above-described measurement configuration are two independent sets of configuration information.

[0417] In this embodiment, the second configuration information is explained independently of the aforementioned measurement configuration. As shown in Figure 15, the method further includes:

[0418] Step 1020: The network device sends second configuration information, which is used to indicate one or more antenna groups.

[0419] In some embodiments, step 1020 corresponds to reporting step 520. That is, the network device sends second configuration information to the terminal device.

[0420] It should be noted that step 1020 can be implemented as a standalone embodiment. Alternatively, step 1020 can be combined with step 720 in one embodiment, with step 1020 preceding step 720. Alternatively, step 1020 can be combined with step 820 in one embodiment, with steps 1020 and 820 not necessarily in a specific order. Alternatively, step 1020 can be combined with step 920 in one embodiment, with steps 1020 and 920 not necessarily in a specific order. Alternatively, step 1020 can be combined with steps 720 and 820 in one embodiment, with steps 1020 and 820 preceding step 720, but steps 1020 and 820 not necessarily in a specific order. Alternatively, step 1020 can be combined with steps 720 and 920 in one embodiment, where steps 1020 and 920 precede step 720, but the order of steps 1020 and 920 is not important. Alternatively, step 1020 can be combined with steps 820 and 920 in one embodiment, where the order of steps 1020, 820, and 920 is not important. Alternatively, step 1020 can be combined with steps 720, 820, and 920 in one embodiment, where steps 1020, 920, and 820 precede step 720, but the order of steps 1020, 820, and 920 is not important.

[0421] In some embodiments, the measurement report received by the network device refers to the measurement report reported by the terminal device described above.

[0422] In some embodiments, the measurement report may not include the antenna group index and / or reference signal resource set index. For example, the terminal device reports a first bitmap to the network device to inform the network device which of the N antenna groups the measurement report corresponds to. As shown in Figure 16, the above method further includes:

[0423] Step 1120: The network device receives a first bitmap, which is used to indicate one or more antenna groups among N antenna groups.

[0424] In some embodiments, step 1120 corresponds to reporting step 620. That is, the network device receives the first bitmap sent by the terminal device.

[0425] In some embodiments, the first bitmap is carried in the measurement report; or, the first bitmap and the measurement report are independent of each other.

[0426] It should be noted that when the first bitmap is included in the measurement report, steps 1120 and 720 above are actually one step. When the first bitmap and the measurement report are independent of each other, the first bitmap can accurately indicate which of the N antenna groups the one or more antenna groups corresponding to the measurement report belong to.

[0427] Step 1120 described above can be implemented as a single embodiment. Alternatively, step 1120 can be combined with step 720 to form an embodiment, with step 1120 preceding step 720.

Alternatively, step 1120 can be combined with steps 720 and 920 in one embodiment, where steps 1120 and 920 precede step 720, but the order of steps 1120 and 920 is not important. Alternatively, step 1120 can be combined with steps 720 and 1020 in one embodiment, where steps 1120 and 1020 precede step 720, but the order of steps 1120 and 1020 is not important.

[0428] In some embodiments, after receiving a measurement report, the network device may also reconstruct the measurement information corresponding to one or more antenna groups based on the measurement report.

[0430] In some embodiments, when the measurement report is of form two described above, after receiving the measurement report, the network device needs to reconstruct the corresponding measurement quantity for each first differential value. For example, the measurement quantity corresponding to the first differential value 1 in antenna group 1 = the first maximum value corresponding to antenna group 1 ± the first differential value 1 in antenna group 1. For instance, if the first differential value 1 in antenna group 1 = the measurement quantity corresponding to the first differential value 1 in antenna group 1 - the first maximum value corresponding to antenna group 1, then the measurement quantity corresponding to the first differential value 1 in antenna group 1 = the first maximum value corresponding to antenna group 1 + the first differential value 1 in antenna group 1. If the first differential value 1 in antenna group 1 = the first maximum value corresponding to antenna group 1 - the measurement quantity corresponding to the first differential value 1 in antenna group 1, then the measurement quantity corresponding to the first differential value 1 in antenna group 1 = the first maximum value corresponding to antenna group 1 - the first differential value 1 in antenna group 1.
