Description

Technical Field

[0001] This application claims priority to Chinese Patent Application No. 202310165232.1, titled "Measurement Method and Communication Device", filed with the China National Intellectual Property Administration on February 17, 2023, and incorporates it herein in its entirety by reference. This application relates to the field of communication technologies, and more specifically, to measurement methods and communication devices.

Background Art

[0002] In a subband full duplex (SBFD) solution of a time division duplex (TDD) system, one component carrier includes at least one subband, and the transmission directions of the subbands on the same symbol can be different. Specifically, the transmission directions of some subbands are uplink, and the transmission directions of some subbands are downlink. In other words, the transmission directions of different subbands within one component carrier can be different. The signal power within a subband may leak into adjacent subbands, which causes interference between the uplink and the downlink, called cross-link interference (CLI). CLI between terminal devices affects the communication quality of the terminal devices. Therefore, it is necessary to measure CLI between terminal devices.

[0003] Currently, a terminal device can measure a sounding reference signal (SRS) transmitted by an interfering terminal device and feedback the SRS measurement result to a network device. However, in this method, the network device cannot obtain the variation of CLI between terminal devices more quickly.

Summary of the Invention

[0004] This application provides a measurement method and communication device that enable network devices to acquire CLI fluctuations between terminal devices more quickly.

[0005] According to a first embodiment, a measurement method is provided. The method includes a first terminal device receiving one or more measurement signals, the one or more measurement signals including a first measurement signal. The first terminal device transmits one or more measurement reports to a network device on at least one of a physical uplink control channel and a physical uplink sharing channel, the one or more measurement reports including a first measurement report, the first measurement report including information obtained by performing crosslink interference measurements based on the first measurement signal. The reporting type of the first measurement report includes aperiodic reporting or semi-persistent reporting.

[0006] Optionally, the reporting type of the first measurement report may further include periodic reporting or event-triggered reporting.

[0007] The terminal device reports measurement reports to the network device on the physical uplink control channel (PUCCH) and / or the physical uplink shared channel (PUSCH). As a result, in this application, the terminal device can report measurement reports to the network device more flexibly and quickly in a Level 1 (L1) and / or Level 2 (L2) manner. Thus, the network device can acquire CLI fluctuations between terminal devices more quickly.

[0008] In one possible implementation, the first terminal device reports a first measurement report to the network device via PUCCH and / or PUSCH using L1 and / or L2 methods, and the first measurement report is transmitted via the user plane of the wireless protocol.

[0009] In one possible implementation, the method further includes a first terminal device receiving first control information from a network device, the first control information being used to trigger the first terminal device to report a first measurement report to the network device.

[0010] Thus, the first terminal device reports a measurement report to the network device based on the control information distributed by the network device, and therefore the network device schedules and controls the reporting of measurement reports by the first terminal device.

[0011] In one possible implementation, the reporting type is semi-persistent reporting, and the first control information is scrambled using a first identifier, and the first control information includes a first field and a second field. The first field instructs to report a first measurement report, and the second field is used to activate or deactivate semi-persistent reporting, with a maximum number of bits of 6 or more in the first field.

[0012] Thus, in this application, existing field designs that instruct the reporting of channel state information (CSI) reports can still be used to conform to existing protocols, and only the maximum number of bits in the first field is changed so that the first field can complete the function of instructing the reporting of CLI measurement reports.

[0013] In one possible implementation, the reporting type is semi-persistent reporting, and the first control information is scrambled using a first identifier, and the first control information includes a first field and a second field. The first field instructs to report a first measurement report, and the second field is a special domain field for activating or deactivating the first measurement report, which is valid on the physical downlink control channel. The first field is different from the third field, which is a channel status information indicator field within the downlink control information, as the downlink control information is used to activate or deactivate semi-persistent channel status information reporting.

[0014] Thus, in this application, the existing field design that instructs reporting a CSI report is still used to conform to existing protocols, and only the design of the first field is modified so that the first field can complete the function of instructing reporting a CLI measurement report.

[0015] In one possible implementation, the reporting type is semi-persistent reporting, and the first control information is scrambled using a first identifier, and the first control information includes a first field and a second field. The first field instructs to report a first measurement report, and the second field is a special domain field for activating or deactivating the first measurement report, which is valid on the physical downlink control channel. The second field is distinct from a fourth field, which is a special domain field within the downlink control information used to activate or deactivate semi-persistent channel status information reporting.

[0016] Thus, in this application, the existing field design that directs the reporting of the CSI report is still used to conform to the existing protocol, and only the design of the second field is modified so that the second field can complete the function of activating or deactivating the semi-permanent reporting of the first measurement report.

[0017] In one possible implementation, the reporting type is semi-persistent reporting, and the first control information is scrambled using a first identifier. The first identifier is different from a second identifier, which is used to scramble downlink control information to activate or deactivate semi-persistent channel status information reporting.

[0018] Optionally, the first control information includes a first field and a second field. The first field instructs the reporting of a first measurement report, and the second field is a special domain field valid on the physical downlink control channel for activating or deactivating the first measurement report.

[0019] Thus, in this application, the existing field design that instructs reporting of a CSI report is still used to conform to the existing protocol, and only the design of the first identifier is modified so that the first identifier can complete the function of indicating that the first control information is for triggering the reporting of the first measurement report.

[0020] In one possible implementation, the reporting type is aperiodic reporting, and the first control information includes a first field, which indicates reporting a first measurement report. The first field is the same as the second field and the maximum number of bits in the first field is 6 or more, or the first field is different from the second field. The second field indicates reporting a channel status information report.

[0021] Thus, in this application, the existing field design that instructs reporting a CSI report is still used to conform to existing protocols, and only the design of the first field is modified so that the first field can complete the function of instructing reporting a CLI measurement report.

[0022] In one possible implementation, the method further includes a first terminal device receiving second control information from a network device, the second control information instructing M terminal devices to do at least one of the following: transmit a measurement signal, measure CLI, or report a CLI measurement report. The M terminal devices include the first terminal device.

[0023] The second control information instructs multiple terminal devices to perform at least one of the following actions: sending a measurement signal, performing a CLI measurement, and reporting a CLI measurement report. This helps reduce signaling overhead, allows for more flexible scheduling of measurement signal transmission, CLI measurements, and CLI measurement report reporting from multiple terminal devices, reduces the resource overhead of the measurement signal, reduces unnecessary CLI measurement reports, and improves system efficiency.

[0024] In one possible implementation, the second control information includes N subblocks, the first of which instructs the associated terminal devices among the M terminal devices to either transmit a measurement signal, measure CLI, or report a CLI measurement report.

[0025] Thus, flexible scheduling of multiple terminal devices can be achieved.

[0026] In one possible implementation, the method further includes the first terminal device receiving at least one of the first information and the second information from the network device, where the first information includes at least one measurement resource configuration information, the at least one measurement resource configuration information includes a first measurement resource configuration information, and the first measurement resource configuration information is used to configure a first communication resource for the first terminal device to receive a first measurement signal. The second information includes at least one measurement report configuration information, the at least one measurement report configuration information includes a first measurement report configuration information, and the first measurement report configuration information is used to configure a report of a first measurement report.

[0027] According to the above technical solution, in this application, the first terminal device can complete the reception of the measurement signal and the report of the measurement report based on the first information and the second information distributed by the network device.

In embodiments of this application, the chip system may include a chip, or it may include a chip and other discrete components.

[0113] Figure 1 is a diagram of application scenario 100 according to one embodiment of this application. As shown in Figure 1, the communication device in application scenario 100 includes a network device 110, a network device 120, a terminal device 130, and a terminal device 140. Uplink or downlink communication may occur between network device 110 and terminal device 130, and uplink or downlink communication may occur between network device 120 and terminal device 140. This is not limited to this. Terminal devices 130 and 140 may also communicate with each other. For example, terminal device 130 may receive an SRS transmitted by terminal device 140. It should be understood that application scenario 100 is used only as an example for understanding and should not limit the scope of protection claimed in this application.

[0114] In application scenario 100, terminal device 130 is located within the coverage area of ​​network device 110, meaning a connection is established between terminal device 130 and network device 110. Terminal device 140 is located within the coverage area of ​​network device 120, meaning a connection is established between terminal device 140 and network device 120. Downlink or uplink communication between network device 110 and terminal device 130 affects uplink or downlink communication between network device 120 and terminal device 140. In other words, a CLI exists between terminal device 130 and terminal device 140.

[0115] It should be understood that the number of terminal devices and network devices included in application scenario 100 is not limited to this embodiment of this application. Terminal device 130 or terminal device 140 may be any of the terminal devices listed above, or network device 110 or network device 120 may be any of the network devices listed above.

[0116] It should be understood that in application scenario 100, the SBFD solution may be used for communication between network device 110 and terminal device 130, and also for communication between network device 120 and terminal device 140. This is not limited to the above. See Figure 2 for an explanation of SBFD.

[0117] Figure 2 shows a subband full-duplex configuration. As shown in Figure 2, one component carrier (CC) is divided into three subbands, for example, subband #1, subband #2, and subband #3. For example, on symbol #1, the transmission direction configured for subbands #1 and #3 is both downlink (DL), while the transmission direction configured for subband #2 is uplink (UL). Signal power in subband #1 leaks into subband #2, causing interference between DL and UL. In other words, DL communication in subband #1 causes interference to UL communication in subband #2.

[0118] In application scenario 100, in order to perform CLI measurement between terminal device 130 and terminal device 140, terminal device 130 receives SRS from terminal device 140 and measures the SRS. Furthermore, terminal device 130 feeds back the SRS measurement result to network device 110 by using radio resource control (RRC) signaling. However, in this method of reporting SRS measurement results to network device 110, network device 110 cannot acquire CLI fluctuations between terminal device 130 and terminal device 140 more quickly. Specifically, reporting SRS measurement results to network device 110 by terminal device 130 using RRC signaling is a semi-static method with a low reporting frequency, and network device 110 cannot acquire CLI fluctuations between terminal device 130 and terminal device 140 more quickly.

[0119] In view of the technical problems described above, this application provides a measurement method and a communication device that enable a network device to acquire CLI variations between terminal devices more quickly.

[0120] The measurement method and communication device in this embodiment will be described below with reference to the attached drawings.

[0121] Figure 3 is a diagram of the interaction procedure of a measurement method 300 according to one embodiment of this application. The method procedure in Figure 3 can be performed by a terminal device 130 and a network device 110, or by modules and / or components (e.g., chips or integrated circuits) having the corresponding functions mounted on the terminal device 130 and the network device 110. This is not limited to this application. Hereinafter, we will use the terminal device 130 and the network device 110 as examples for illustrative purposes. As shown in Figure 3, the method 300 includes the following steps.

[0122] S310: Terminal device 130 receives one or more measurement signals, and these one or more measurement signals include measurement signal 1.

[0123] Specifically, the one or more measurement signals received by terminal device 130 are from other terminal devices. For example, terminal device 130 may receive measurement signal 1 from terminal device 140, terminal device 130 may receive measurement signal 2 from terminal device 150 (not shown in Figure 1), and terminal device 130 may further receive measurement signal 3 from terminal device 160 (not shown in Figure 1).

[0124] In short, terminal device 130 receives one or more measurement signals from one or more terminal devices, and each measurement signal corresponds to one terminal device. For example, measurement signal 1 corresponds to terminal device 140, measurement signal 2 corresponds to terminal device 150, and measurement signal 3 corresponds to terminal device 160.

[0125] It should be understood that the measurement signal described above is a generalized concept of the signal used for channel measurement. For example, the measurement signal may include SRS or signals specifically introduced for CLI measurement. This is not limited to this.

[0126] In one possible implementation, the measurement signal is the SRS. In a specific implementation, the SRS is an existing SRS used for uplink codebook transmission, an existing SRS used for uplink non-codebook transmission, an existing SRS used for uplink antenna selection, or an existing SRS used for localization. In another specific implementation, the SRS is a dedicated SRS introduced for CLI measurement. This is not limited to this.

[0127] In one possible implementation, SRS has one or more of the following features, namely: • SRS uses a single antenna port (AP); • SRS does not support frequency hopping (FH); and The maximum number of cyclic shifts (CS) in an SRS sequence is greater than 12, for example, 18, 24, 36, or 48.

[0128] In one possible implementation, SRS can be transmitted in a periodic, non-periodic, or semi-persistent manner.

[0129] It should be understood that the above-mentioned aspects of SRS can be implemented independently of the technical solutions in the embodiments of this application.

[0130] S320: Terminal device 130 reports one or more measurement reports to network device 110 on at least one of PUCCH and PUSCH, and the one or more measurement reports include measurement report 1.

[0131] Accordingly, the network device 110 receives one or more measurement reports reported by the terminal device 130 on at least one of PUCCH and PUSCH.

[0132] It can be understood that each measurement report corresponds to at least one measurement signal. For example, measurement report 1 corresponds to measurement signal 1. More specifically, measurement report 1 includes information, in other words, measurement results or measurement reports, obtained by the terminal device 130 by performing a CLI measurement on measurement signal 1.

[0133] Specifically, terminal device 130 performs CLI measurement on the received measurement signal and obtains a measurement report associated with the measurement signal. Correspondingly, terminal device 130 reports the measurement report to network device 110 on PUCCH and / or PUSCH, and network device 110 determines the variation in CLI between terminal devices based on the measurement report. For example, network device 110 obtains the variation in CLI between terminal device 130 and terminal device 140 based on measurement report 1 (corresponding to measurement signal 1), network device 110 obtains the variation in CLI between terminal device 130 and terminal device 150 based on measurement report 2 (corresponding to measurement signal 2), and network device 110 obtains the variation in CLI between terminal device 130 and terminal device 150 based on measurement report 3 (corresponding to measurement signal 3).

[0134] In short, by having the terminal device report measurement reports to the network device on PUCCH and / or PUSCH, this application allows the terminal device to report measurement reports to the network device more flexibly and quickly. Thus, the network device can acquire CLI variations between terminal devices more quickly.

[0135] Optionally, the terminal device 130 can report measurement reports on PUCCH and / or PUSCH in Level 1 and / or Level 2 manner, and the measurement reports can be considered to be transmitted via the user plane of the wireless protocol.

[0136] Optionally, in one possible implementation, method 300 may further include the following:

[0137] S310a: The network device 110 transmits at least one of information 1 and information 2 to the terminal device 130, where information 1 includes at least one measurement resource configuration information and information 2 includes at least one measurement report configuration information.

[0138] Specifically, each of at least one measurement resource configuration information is used to configure one communication resource, which is used by the terminal device 130 to receive the measurement signal. For example, at least one measurement resource configuration information includes measurement resource configuration information 1, which is used to configure communication resource 1, and the terminal device 130 receives the measurement signal 1 by using communication resource 1. Each of at least one measurement report configuration information is used to configure the reporting of a measurement report. For example, at least one measurement report configuration information includes measurement report configuration information 1, which is used to configure the reporting of measurement report 1, which is obtained by the terminal device 130 by performing a CLI measurement on the measurement signal 1. Thus, the terminal device 130 can receive the measurement signal and report a measurement report based on information 1 and information 2 distributed by the network device, and therefore the network device 110 schedules and controls the terminal device 130.

[0139] It can be understood that if network device 110 delivers only information 1 to terminal device 130, information 2 can be configured in a protocol-defined manner, and network device 110 does not need to show terminal device 130 how to report the measurement report. If network device 110 delivers only information 2 to terminal device 130, information 1 can be configured in a protocol-defined manner, and network device 110 does not need to show terminal device 130 how to receive the measurement signal.

[0140] In one possible implementation, the measurement resource configuration information 1 includes an identifier for the communication resource 1, time-domain resource information, frequency-domain resource information, sequence information for the measurement signal 1, and transmission power information for the measurement signal 1. The time-domain resource information includes the time-domain resource type (e.g., periodic, aperiodic, or semi-persistent). Thus, the network device 110 presents the above information to the terminal device 130, and as a result, the terminal device 130 can receive the measurement signal 1 based on the communication resources indicated by the information.

[0141] It should be understood that the information included in the measurement state configuration information 1 may be all of the information listed above, or only some of the information listed above. This is not limited to this. This information can be used by the terminal device 130 to receive the measurement signal.

[0142] It can be understood that if communication resource 1 is configured to be periodic, it means that communication resource 1 appears periodically. The measured resource configuration information 1 may include periodicity, offset, starting position within a slot, or duration. If communication resource 1 is configured to be aperiodic, it means that communication resource 1 appears aperiodicly, and signaling is required to further trigger or instruct communication resource 1 to become active. For example, L1 / L2 signaling may be used, which may include media access control-control element (MAC CE) or downlink control information (DCI). If communication resource 1 is configured to be semi-persistent, signaling is required to further trigger or instruct the activation of communication resource 1 so that communication resource 1 can subsequently appear periodically.

[0143] Optionally, an activated semi-persistent communication resource may also be deactivated, for example, by using MAC CE or DCI. When a communication resource is deactivated, it will not appear periodically. If the communication resource 1 is configured to be periodic or semi-persistent, the measured resource configuration information 1 may further include periodicity, offset, starting position within a slot, or duration.

[0144] In addition, the frequency domain resource information within the measurement resource configuration information 1 includes at least one of the following: frequency domain start position, bandwidth, or subcarrier spacing (SCS). Thus, when the network device 110 provides any of the above information to the terminal device 130, the terminal device 130 can receive the measurement signal 1 based on the frequency domain resource indicated by any of the above information.

[0145] It should be understood that the information contained in the frequency domain resource information within the measurement resource configuration information 1 may be all of the information listed above, or only some of the information listed above. This is not limited to this. This information can be used by the terminal device 130 to receive the measurement signal.

[0146] In one possible implementation, the frequency domain location of communication resource 1 changes along with the reported indicators (including the reference signal received power (RSRP) and the received signal strength indicator (RSSI) of the CLI). For example, terminal device 130 measures the RSRP of the measurement signal in the uplink subband, and terminal device 130 measures the RSSI of the CLI in the downlink subband. It can be understood that the measurement signal 1 is transmitted in the uplink subband.

[0147] Furthermore, the terminal device 130 transmits the measurement signal and performs CLI measurements only within the active bandwidth part (BWP). For example, the terminal device 130 measures the RSRP of the measurement signal within the active UL BWP in the UL subband, and measures the RSSI of the CLI within the active DL BWP in the DL subband.

[0148] Furthermore, for a typical configuration of SBFD {DUD}, two discontinuous DL subbands may exist, and measurement resources for the RSSI of CLI (which are primarily frequency-domain resources) can be shown in several ways: 1. Measurements are performed in only one of the DL subbands, and a specific DL subband is indicated by the network device 110 either by being predefined in the protocol or by using signaling; 2. Measurements were performed in two DL subbands, which specifically included: (a) Two discontinuous DL subband resources are defined as two measurement resources; (b) Two discontinuous DL subband resources are defined as a single measurement resource, which may specifically include: i. The measurement resource consists of two frequency domain start positions and / or bandwidths; ii. A measurement resource consists of a single frequency domain start position and / or bandwidth. If the configured frequency domain resource includes a UL subband resource, the configured frequency domain resource is not a resource for the CLI's RSSI by default.

[0149] Please refer to Figure 4 for the frequency domain resource configuration of {DUD}.

[0150] Figure 4 shows a frequency domain resource configuration according to one embodiment of this application. As shown in Figure 4(a), when there are two discontinuous DL subbands (these two DL subbands are separated by an UL subband), the network device 110 indicates a specific DL subband by using frequency domain resource information in Information 1 (see Method 1). As shown in Figure 4(b), when there are two discontinuous DL subbands, the network device 110 indicates the two DL subbands separately by using frequency domain information in Information 1 (see the first possible method in Method 2b). As shown in Figure 4(c), when there are two discontinuous DL subbands, the network device 110 indicates these three subbands by using frequency domain resource information in Information 1 (see the second possible method in Method 2b), and it may be defined that the UL subband is not used for measuring the RSSL of the CLI. Correspondingly, the terminal device 130 measures the RSSI of the CLI based on the frequency domain resources indicated by the frequency domain resource information in Information 1.

[0151] In one possible implementation, for measurement reports in two DL subbands in Method 2, the terminal device 130 may report the two measurement reports separately, report the sum of the two measurement reports, or report the average of the two measurement reports. Regarding the method of reporting two measurement reports, the terminal device 130 can report two measurement reports, or it can report two measurement reports using a differential reporting method. For example, the terminal device 130 may report the measurement report for the first DL subband and also report the difference obtained by subtracting the measurement report for the first DL subband from the measurement report for the second DL subband. This is not limited to this.

[0152] In one possible implementation, measurement report configuration information 1 may be used to configure the reporting type of measurement report 1. Specifically, the reporting type of measurement report 1 may include one of the following: periodic reporting, non-periodic reporting, and semi-permanent reporting.

[0153] In the case of periodic reporting, the measurement report configuration information 1 includes an identifier for the measurement report configuration information 1, an identifier for communication resource 1, periodicity, offset, PUCCH resource, reporting indicator, or reporting granularity. Since the measurement report configuration information 1 is associated with communication resource 1, it may include an identifier for communication resource 1. The reporting granularity indicates whether the measurement report 1 is at the subband level or the broadband level. In periodic reporting, the terminal device 130 may report the measurement report 1 to the network device 110 on the PUCCH.

[0154] In the case of semi-persistent reporting, terminal device 130 may report measurement report 1 on PUCCH or on PUSCH. In the case of semi-persistent reporting on PUCCH, this application supports the “RRC configuration + MAC CE activation / deactivation” method. Specifically, network device 110 first configures measurement report configuration information 1 by using RRC signaling, and measurement report configuration information 1 includes an identifier for measurement report configuration information 1, an identifier for communication resource 1, periodicity, offset, PUCCH resource, report indicator, or report granularity. Furthermore, network device 110 activates or deactivates periodic reporting by using MAC CE. Thus, terminal device 130 decides to report the configuration information of measurement report 1 to network device 110 in order to better complete the reporting of the measurement report to network device 110.

[0155] For semi-permanent reporting on PUSCH, this application supports a “RRC configuration + DCI activation / deactivation” scheme. Specifically, the network device 110 first configures measurement report configuration information 1 by using RRC signaling, and the measurement report configuration information 1 includes an identifier for measurement report configuration information 1, an identifier for communication resource 1, periodicity, offset, PUSCH resource, reporting indicator, or reporting granularity. Furthermore, the network device 110 activates or deactivates periodic reporting by using DCI.

[0156] In the case of aperiodic reporting, terminal device 130 can report measurement report 1 on PUSCH. This application supports the “RRC configuration + DCI activation” method. Specifically, network device 110 first configures measurement report configuration information 1 by using RRC signaling, and measurement report configuration information 1 includes an identifier for measurement report configuration information 1, an identifier for communication resource 1, a report indicator, or report granularity. Furthermore, network device 110 activates aperiodic reporting by using DCI.

[0157] Optionally, the reporting type for Measurement Report 1 may further include event-triggered reporting. Event-triggered reporting means that the measurement report is triggered only when an event occurs. In one possible implementation, the reporting of the corresponding measurement result is triggered only when the measured SRS-RSRP or CLI-RSSI exceeds a certain threshold. Otherwise, the report is not triggered. In one possible implementation, event-triggered reporting is carried over PUCCH or PUSCH. In one possible implementation, event triggering can be combined with other reporting types, such as periodic reporting + event-triggered reporting, aperiodic reporting + event-triggered reporting, or semi-persistent reporting + event-triggered reporting. In one possible implementation, event triggering can exist independently of other reporting types.

[0158] In one possible implementation, the measurement signal and measurement report type satisfy the following relationship: [Table 1]

[0159] Specifically, this application supports different types of reporting methods for different types of measurement signals. For example, for periodic measurement signals, this application supports periodic measurement reports, semi-permanent measurement reports, and aperiodic measurement reports. For semi-permanent measurement signals, this application supports either semi-permanent measurement reports or aperiodic measurement reports, but does not support periodic measurement reports. For aperiodic measurement signals, this application supports only aperiodic measurement reports, and does not support periodic reports or semi-permanent measurement reports.

[0160] Optionally, for semi-permanent or non-periodic reporting, Method 300 may further include:

[0161] S310b: Terminal device 130 receives control information 1 from network device 110, and control information 1 is intended to trigger terminal device 130 to report measurement report 1 to network device 110.

[0162] Specifically, control information 1 is downlink control information. For example, control information 1 can be in DCI format 0_1 ​​or DCI format 0_2.

[0163] Specifically, if the reporting type of measurement report 1 is a semi-permanent report, the following implementations are possible:

[0164] In one possible implementation, control information 1 is scrambled using identifier 1, and control information 1 further includes field 1 and field 2. Field 1 instructs to report measurement report 1, and field 2 is a special domain field valid on the physical downlink control channel (PDCCH) for activating or deactivating measurement report 1, with a maximum number of bits of field 1 being 6 or more. For example, identifier 1 may be semi-persistent channel state information-radio network temporary identifier (SP-CSI-RNTI). For example, field 1 is a CSI request indicator field. For example, field 2 includes the following fields and their corresponding value settings.

[0165] In Example 1, when Field 2 is used to activate Measurement Report 1, please refer to Table 1 for the format of Field 2. [Table 2]

[0166] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number and the redundant version bit field in field 2 are all set to 0, indicating to terminal device 130 that measurement report 1 is to be activated. For the meaning of the hybrid auto-retransmission request process number and redundant version, please refer to existing standards. Further details will not be explained here.

[0167] In Example 2, when Field 2 is used to deactivate Measurement Report 1, please refer to Table 2 for the format of Field 2. [Table 3]

[0168] μ is a parameter related to SCS. When μ=0, SCS=15kHz. When μ=1, SCS=30kHz.

[0169] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number in field 2 are all set to 0, the bit field values ​​for the modulation / coding scheme are all set to 1, the bit field values ​​for resource block allocation are all set to 0 or all set to 1 based on the different RA types, and the bit field values ​​for the redundant version are all set to 0, indicating to terminal device 130 that measurement report 1 is to be deactivated. For the meaning of modulation / coding scheme and resource block allocation, please refer to existing standards. Details will not be explained again here.

[0170] In one possible implementation, control information 1 is scrambled using identifier 1, and control information 1 includes fields 3 and 4. Field 3 instructs to report measurement report 1, and field 4 is a special domain field valid on PDCCH for activating or deactivating measurement report 1. Field 3 is a new field and is different from the CSI indicator field in the downlink control information for activating or deactivating semi-persistent CSI reporting. For example, identifier 1 may be SP-CSI-RNTI. For example, field 4 includes the following fields and their corresponding value settings.

[0171] In Example 3, when Field 4 is used to activate Measurement Report 1, please refer to Table 3 for the format of Field 4. [Table 4]

[0172] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number and the redundant version bit field values ​​in field 4 are all set to 0, indicating to the terminal device 130 that measurement report 1 is to be activated.

[0173] In Example 4, when Field 4 is used to deactivate Measurement Report 1, please refer to Table 4 for the format of Field 4. [Table 5]

[0174] Specifically, the bit field values ​​for the hybrid auto retransmission request process number in field 4 are all set to 0, the bit field values ​​for the modulation / coding method are all set to 1, the bit field values ​​for resource block allocation are all set to 0 or all set to 1 based on the different RA types, and the bit field values ​​for the redundant version are all set to 0, indicating to the terminal device 130 that measurement report 1 is to be deactivated.

[0175] In one possible implementation, control information 1 is scrambled using identifier 1, and control information 1 includes fields 5 and 6. Field 5 instructs the reporting of measurement report 1, and field 6 is a special domain field valid on PDCCH for activating or deactivating measurement report 1. Field 6 is a new field and is different from the special domain field used to activate or deactivate semi-persistent CSI reporting in existing downlink control information. For example, identifier 1 may be SP-CSI-RNTI.

[0176] In Example 5, when Field 6 is used to activate Measurement Report 1, please refer to Table 5 for the format of Field 6. [Table 6]

[0177] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number and the redundant version bit field values ​​in field 6 are all set to 1, indicating to the terminal device 130 that measurement report 1 is to be activated.

[0178] In Example 6, when Field 6 is used to deactivate Measurement Report 1, please refer to Table 6 for the format of Field 6. [Table 7]

[0179] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number in field 6 are all set to 1, the bit field values ​​for the modulation / coding scheme are all set to 1, the bit field values ​​for resource block allocation are all set to 0 or all set to 1 based on the different RA types, and the bit field values ​​for the redundant version are all set to 1, indicating to the terminal device 130 that measurement report 1 is to be deactivated.

[0180] In one possible implementation, control information 1 is scrambled using identifier 1, and control information 1 further includes fields 7 and 8. Field 7 instructs to report measurement report 1, and field 8 is a special domain field valid on PDCCH for activating or deactivating measurement report 1. Identifier 2 is a new identifier, different from the existing identifier used to scramble DCI for activating or deactivating semi-persistent CSI reporting, i.e., SP-CSI-RNTI. For example, identifier 2 is SP-CLI-RNTI. For example, field 8 includes the following fields and their corresponding value settings.

[0181] In Example 7, when Field 8 is used to activate Measurement Report 1, please refer to Table 7 for the format of Field 8. [Table 8]

[0182] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number and the redundant version bit field values ​​in field 8 are all set to 0, indicating to the terminal device 130 that measurement report 1 is to be activated.

[0183] In Example 8, when Field 8 is used to deactivate Measurement Report 1, please refer to Table 8 for the format of Field 8. [Table 9]

[0184] Specifically, the bit field values ​​for the hybrid auto-retransmission request process number in field 8 are all set to 0, the bit field values ​​for the modulation / coding method are all set to 1, the bit field values ​​for resource block allocation are all set to 0 or all set to 1 based on the different RA types, and the bit field values ​​for the redundant version are all set to 0, indicating to the terminal device 130 that measurement report 1 is to be deactivated.

[0185] Specifically, if the reporting type of measurement report 1 is aperiodic report, control information 1 includes field 9, which is used to trigger terminal device 130 to report measurement report 1 to network device 110. Field 9 can be a new field, different from existing fields used to trigger the reporting of CSI reports; for example, field 9 could be a CLI request indicator field. Alternatively, field 9 may be an existing field used to trigger the reporting of CSI reports, but the maximum number of bits for field 9 is 6 or more.

[0186] Optionally, in one possible implementation, method 300 may further include the following:

[0187] S310c: Terminal device 130 receives control information 2 from network device 110, and control information 2 instructs M terminal devices to do at least one of the following: send a measurement signal, measure CLI, or report a CLI measurement report.

[0188] It can be understood that network device 110 can transmit control information 2 to M terminal devices, and M terminal devices include terminal device 130. Terminal device 130 performs actions based on the content indicated by control information 2. For example, when control information 2 instructs to perform a CLI measurement, terminal device 130 performs a CLI measurement; when control information 2 instructs to transmit a measurement signal, terminal device 130 can transmit a measurement signal to another terminal device; when control information 2 instructs to report a CLI measurement report, terminal device 130 reports a CLI measurement report to network device 110; when control information 2 instructs to transmit a measurement signal and measure the CLI, terminal device 130 transmits a measurement signal and measures the CLI based on the instructions of control information 2; or when control information 2 instructs to transmit a measurement signal, measure the CLI, and report a CLI measurement report, terminal device 130 transmits a measurement signal, measures the CLI, and reports a CLI measurement report based on the instructions of control information 2.

[0189] It can be further understood that the M terminal devices may or may not all be within the coverage area of ​​network device 110. If some terminal devices are not within the coverage area of ​​network device 110, network device 110 may interact with another network device to distribute control information 2 to terminal devices within that network device's coverage area.

[0190] In one possible implementation, control information 2 is downlink control information and is a common DCI for the terminal device group (UE-group common). The downlink control information is scrambled using a common RNTI for the terminal device group, and this RNTI may be composed of network devices.

[0191] In one possible implementation, control information 2 includes N subblocks, and subblock 1 within the N subblocks instructs the associated terminal device among the M terminal devices to do at least one of the following: transmit a measurement signal, measure CLI, or report a CLI measurement report. For example, each subblock includes two bits, the first bit being a measurement signal transmission indicator field and the second bit being a CLI measurement indicator field. An example of the instruction status is shown in Table 9. [Table 10]

[0192] For example, as can be seen from Table 9, a bit status of 00 can indicate that no measurement signal is sent and no CLI measurement is performed; a bit status of 01 can indicate that no measurement signal is sent and a CLI measurement is performed; a bit status of 10 can indicate that a measurement signal is sent and no CLI measurement is performed; or a bit status of 11 can indicate that a measurement signal is sent and a CLI measurement is performed. The above is used only as an example for understanding and should not be used as a final limitation.

[0193] It can be understood that the CLI measurement indicator field may only include the meaning of measuring the CLI, or it may further include the meaning of reporting a CLI measurement report, for example, the CLI measurement indicator field instructs the terminal device 130 to measure the CLI but not to report a CLI measurement report, or the CLI measurement indicator field instructs the terminal device 130 to measure the CLI and report a CLI measurement report. When the CLI measurement indicator field instructs the terminal device 130 to measure the CLI but not to report a CLI measurement report, this application supports each subblock including an additional bit (i.e., 3 bits), the bit indicating whether a CLI measurement report should be reported, etc.

[0194] Furthermore, after receiving control information 2, terminal device 130 decides whether to transmit a measurement signal and / or perform a CLI measurement based on the subblock associated with terminal device 130 in control information 2. Furthermore, based on the content indicated by another subblock, it is decided whether to perform the corresponding CLI measurement at the corresponding time. If no other terminal device transmits a measurement signal at the corresponding time, terminal device 120 does not perform the corresponding CLI measurement at that time; otherwise, terminal device 130 performs the corresponding CLI measurement at that time.

[0195] For example, five terminal devices form a group. The measurement signal transmission and CLI measurement report behavior of UE1 to UE5 are as follows: 1. UE1: Sends measurement signal 1 at time T1; 2. UE2: Sends measurement signal 2 at time T2 and measures measurement signal 1 at time T1; 3. UE3: Sends measurement signal 3 at time T3, measures measurement signal 1 at time T1, and measures measurement signal 2 at time T2; 4. UE4: Transmits measurement signal 4 at time T4, measures measurement signal 1 at time T1, measures measurement signal 2 at time T2, and measures measurement signal 3 at time T3; 5. UE5: Does not transmit measurement signal 5, measures measurement signal 1 at time T1, measure measurement signal 2 at time T2, measure measurement signal 3 at time T3, and measure measurement signal 4 at time T4.

[0196] It can be understood that the network device 110, by using RRC signaling, transmits the measurement signal transmission pattern (or referred to as the configuration information of the measurement signal) and the CLI measurement pattern (or referred to as the CLI measurement configuration information) of UE1 to UE5 to UE1 to UE5, and constitutes five subblocks in the corresponding control information 2 to separately indicate to each UE whether to transmit a measurement signal and / or perform a CLI measurement report. The network device 110 dynamically and separately instructs UE1 to UE5 whether to transmit a measurement signal and / or perform a CLI measurement report by using the control information 2. In other words, instead of information about when UE1 to UE5 transmit the measurement signal being shown by the control information 2, it can be configured by the network device 110 by using RRC signaling. That is, the network device 110 only indicates whether a measurement signal should be transmitted by using the control information 2, and does not further indicate information such as when the measurement signal is transmitted.

[0197] In short, when terminal device 130 determines, based on control information 2, that another terminal device will transmit a measurement signal, terminal device 130 can determine the timing of when the other terminal device will transmit the measurement signal based on the measurement signal transmission pattern of the other terminal device configured by network device 110, and complete the CLI measurement.

[0198] For example, if control information 2 instructs UE5 and UE2 to perform CLI measurement without sending a measurement signal, and instructs UE1, UE3, and UE4 to send a measurement signal and perform CLI measurement, the behavior of UE1 through UE5 will be as follows: 1. UE1: Sends measurement signal 1 at time T1; 2. UE2: Does not transmit measurement signal 2, but measures measurement signal 1 at time T1; 3. UE3: Sends measurement signal 3 at time T3 and measures measurement signal 1 at time T1; 4. UE4: Transmits measurement signal 4 at time T4, measures measurement signal 1 at time T1, and measures measurement signal 3 at time T3; 5. UE5: Does not transmit measurement signal 5, measures measurement signal 1 at time T1, measures measurement signal 3 at time T3, and measures measurement signal 4 at time T4.

[0199] Control information 2 instructs multiple terminal devices to perform at least one of the following: transmit a measurement signal, perform a CLI measurement, and report a CLI measurement. This helps reduce signaling overhead, allows for more flexible scheduling of measurement signal transmission, CLI measurement, and CLI measurement report reporting by multiple terminal devices, reduces the resource overhead of the measurement signal, reduces unnecessary CLI measurement reports, and improves system efficiency.

[0200] The order in which S310a to S310c are performed is not limited in this application.

[0201] Method 300 will be further described below with reference to additional attached drawings.

[0202] Figure 5 is a diagram of the interaction procedure of a measurement method 500 according to one embodiment of this application. The method procedure in Figure 5 can be performed by terminal devices 130, 150, and network device 110, or by modules and / or components (e.g., chips or integrated circuits) having the corresponding functions mounted on terminal devices 130, 150, and network device 110.

[0203] S510: The network device 110 transmits information 3 to the terminal device 150, and information 3 is used to configure the transmission of the measurement signal 2.

[0204] Accordingly, the terminal device 150 receives information 3 from the network device 110 and determines the configuration parameters used to transmit the measurement signal 2 based on the information 3.

[0205] It can be understood that terminal devices 150 and 130 may be located within the coverage area of ​​network device 110.

[0206] For example, information 3 may include configuration information for the measurement signal 2, which may include content such as time-domain resource information, frequency-domain resource information, code-domain information, and power information.

[0207] S520: Network device 110 transmits information 1 and information 2 to terminal device 130.

[0209] S530: Terminal device 150 transmits measurement signal 2 to terminal device 130.

[0211] S540: Terminal device 130 measures measurement signal 1 and obtains measurement report 2.

[0212] S550: Terminal device 130 sends measurement report 2 to network device 110 via PUCCH and / or PUSCH.

The communication device 900 may be configured to perform operations performed by the network device 110 in the method embodiments shown in Figures 3 and 5.

[0250] If the communication device 900 is a network device 110 such as a base station, Figure 9 shows a simplified configuration of the base station. The base station includes parts 910, 920, and 930. Part 910 is mainly configured to perform baseband processing and control the base station. Part 910 is usually the control center of the base station and can usually be referred to as a processor and is configured to control the base station to perform the processing operations on the network device side in the embodiments of the method described above.

The receiver may also be referred to as a receiving module, receiver, or receiver circuit, and the transmitter may also be referred to as a transmitting module, transmitter, or transmitter circuit.

[0251] Parts 910 and 920 may include one or more boards, each board may include one or more processors and one or more memories. The processors are configured to read and execute programs from memory to implement baseband processing functions and control base stations. If multiple boards are present, they may be interconnected to increase processing power. In one optional implementation, multiple boards may share one or more processors, multiple boards may share one or more memories, or multiple boards may share one or more processors simultaneously.

[0252] For example, in one implementation, the transceiver module in part 930 is configured to perform receive and transmit related processes that are performed by the network device in the embodiments shown in Figures 3 to 5. The processor in part 910 is configured to perform processing related processes that are performed by the network device in the embodiments shown in Figures 3 to 5.

[0253] In another implementation, the processor within portion 910 is configured to execute processing-related processes performed by the communication device in the embodiments shown in Figures 3 to 5.

[0254] In another implementation, the transceiver module within portion 930 is configured to perform the receive and transmit related processes that are performed by the communication device in the embodiments shown in Figures 3 to 5.

[0255] It should be understood that Figure 9 is merely an example, not an exhaustive one, and the aforementioned network devices, including the processor, memory, and transceiver, do not necessarily have to depend on the configuration shown in Figures 6 through 8.

[0256] If the communication device 900 is a chip, the chip includes a transceiver, memory, and a processor. The transceiver may be an input / output circuit or a communication interface. The processor is a processor, microprocessor, or integrated circuit integrated on the chip. In the above-described method embodiment, the transmission operation performed by the network device can be understood as an output of the chip, and the reception operation performed by the network device in the above-described method embodiment can be understood as an input of the chip.

[0257] Figure 10 is a block diagram of a communication device 1000 according to one embodiment of this application. The communication device 1000 may be a processor or chip of a terminal device 130. The communication device 1000 may be configured to perform operations performed by the terminal device 130 or the communication device in the method embodiment described above.

[0258] When the communication device 1000 is a terminal device 130, Figure 10 shows a simplified configuration of the terminal device. As shown in Figure 10, the terminal device includes a processor, memory, and a transceiver. The memory may store computer program code. The transceiver includes a transmitter 1031, a receiver 1032, a radio frequency circuit (not shown in Figure 10), an antenna 1033, and an input / output device (not shown in Figure 10).

[0259] The processor is primarily configured to process communication protocols and data, control terminal devices, execute software programs, process data within software programs, and perform similar tasks. Memory is primarily configured to store software programs and data. Radio frequency circuits are primarily configured to perform conversions between baseband signals and radio frequency signals and to process radio frequency signals. Antennas are primarily configured to receive and transmit radio frequency signals in the form of electromagnetic waves. Input / output devices, such as touchscreens, displays, or keyboards, are primarily configured to receive data entered by the user and output data to the user. Note that some types of terminal devices may not have input / output devices.

[0260] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted, then outputs the baseband signal to a radio frequency circuit, which performs radio frequency processing on the baseband signal and then transmits the radio frequency signal externally in the form of electromagnetic waves via an antenna. When data is transmitted to a terminal device, the radio frequency circuit receives the radio frequency signal via an antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor. The processor converts the baseband signal into data and processes the data. For ease of explanation, Figure 10 simply shows one memory, one processor, and one transceiver. In actual terminal device products, there may be one or more processors and one or more memories. Memory may also be referred to as a storage medium or storage device, etc. Memory may be located independently of the processor or may be integrated with the processor. This is not limited to the embodiments of this application.

[0263] Optionally, a component within the transceiver 1030 configured to implement a receiving function may be regarded as a receiving module, and a component within the transceiver 1030 configured to implement a transmitting function may be regarded as a transmitting module. That is, the transceiver 1030 includes a receiver and a transmitter. The transceiver is sometimes also referred to as a transceiver machine, a transceiver module, or a transceiver circuit, etc. The receiver is sometimes also referred to as a receiver machine, a receiving module, or a receiver circuit, etc. The transmitter is sometimes also referred to as a transmitter machine, a transmitting module, or a transmitter circuit, etc.

[0264] For example, in one implementation, the processor 1010 is configured to execute the processing operations on the terminal device side in the embodiments shown in FIGS. 3 to 5, and the transceiver 1030 is configured to execute the receiving and transmitting operations on the terminal device side in FIGS. 3 to 5.

[0265] It should be understood that FIG. 10 is merely an example and not a limitation, and the above-mentioned terminal device including a transceiver module and a processing module may not depend on the configurations shown in FIGS. 6 to 8.

[0266] When the communication device 1000 is a chip, the chip includes a processor, a memory, and a transceiver. The transceiver can be an input / output circuit or a communication interface. The processor can be a processing module, a microprocessor, or an integrated circuit integrated on the chip.

The memory is configured to store a computer program or code.
