The communication device may also include other devices in the communication system 100, such as network controllers, mobility management entities, and other network entities. This application embodiment does not limit this.

[0038] Subband non-overlapping full duplex (SBFD)

[0039] To overcome the problems of weak uplink coverage, high uplink latency, and insufficient uplink capacity caused by limited uplink resource allocation in NR Time Division Duplex (TDD), the 3rd Generation Partnership Project (3GPP) introduced SBFD technology in Release 18. SBFD allows simultaneous transmission and reception of data on different subbands within the same subframe / slot / symbol. This technology is primarily used on the network equipment side, while the terminal equipment side retains its current state, meaning that only transmission or reception of data is supported within a single subframe / slot / symbol. As shown in Figure 2, the middle subband of a downlink or flexible subframe / slot / symbol is configured as an uplink subband.

[0040] When the uplink fully occupies the bandwidth, it is considered dynamic TDD technology. This can be seen as an extreme case of SBFD, which allows for dynamic adaptation of the transmission direction of time resources based on time slots.

[0041] Furthermore, in related technologies, SBFD subbands (UL subbands and / or DL ​​subbands) can only be configured on DL symbols and / or flexible symbols configured in TDD-UL-DL-ConfigCommon, i.e., a more likely frame structure is shown in Figure 3.

[0042] Currently, Release 19 only supports semi-static SBFD, meaning that the subframe / time slot / symbol where the SBFD is located, as well as the bandwidth and location of the uplink and downlink subbands, are all configured semi-statically and cannot be dynamically changed. In this case, network equipment from the same operator in different cells, especially neighboring cells, typically has the same configuration. However, for 6G, given the inherent strong self-interference cancellation capabilities of network equipment, and to improve network scheduling flexibility, the duplex mode of network equipment is evolving towards dynamic SBFD and full duplex (FD). Dynamic SBFD means that the subframe / time slot / symbol where the SBFD is located, or the bandwidth and location of the uplink and downlink subbands, are dynamically changed. FD means that the network equipment can simultaneously schedule uplink and / or downlink across the full bandwidth.

[0043] Reporting of cross-link interference (CLI)

[0044] The proposed duplex technologies include Dynamic TDD (Transmission Direction Divided) technology, which flexibly changes the transmission direction of each time slot, and SBFD (Side-Based Frequency Divided) technology, which embeds uplink subbands into downlink time slots. Both technologies face the problem of cross-link interference between terminal devices caused by the flexibility of configuration of each terminal device. That is, when adjacent terminal devices are configured with different transmission directions, the terminal device receiving downlink data will be interfered with by the uplink transmission of adjacent terminal devices. Release 19 establishes a Layer 1 (L1) CLI measurement and reporting mechanism to promptly report cross-link interference to facilitate network device scheduling.

[0045] In response, the relevant technologies also disclose the following content regarding CLI measurement and reporting.

[0046] For ease of discussion, the SRS-RSRP measurement resource index is referred to as SRS-RSRP-MRI, and the CLI-RSSI measurement resource index is referred to as CLI-RSSI-MRI.

[0047] For SRS-RSRP-MRI / SRS-RSRP or CLI-RSSI-MRI / CLI-RSSI reports, the mapping order of the CSI fields in a report is shown in Table 1.

[0048] Table 1: CSI field mapping order in SRS-RSRP-MRI / SRS-RSRP or CLI-RSSI-MRI / CLI-RSSI reports

[0049] Table 2. Bandwidths of SRS-RSRP-MRI, SRS-RSRP, CLI-RSSI-MRI, and CLI-RSSI

[0050] The number of SRS-RSRP measurement resources in the corresponding resource set.

[0051] The number of CLI-RSSI measurement resources in the corresponding resource set.

[0052] In addition, the following information is disclosed regarding the related technologies.

[0053] For L1-based CLI measurements and reporting, the following methods apply: For L1 SRS-RSRP, 7 bits are used for quantization, with a quantization range of [-140, -44] dBm and a step size of 1 dB. Differential L1 SRS-RSRP is quantized with 4 bits. Differential L1 SRS-RSRP values ​​are calculated in 2 dB steps, with the largest measured L1 SRS-RSRP value used as a reference. For L1 CLI-RSSI, 7 bits are used for quantization, with a quantization range of [-100, -25] dBm and a step size of 1 dB. Differential L1 CLI-RSSI is quantized with 4 bits. Differential L1 CLI-RSSI values ​​are calculated in 2 dB steps, with the largest measured L1 CLI-RSSI value used as a reference.

[0054] For the maximum value, it can be reported according to the mapping relationship between the quantized value and the reported value in Table 3 below.

[0055] Table 3: SRS-RSRP Measurement Report Mapping

[0056] L1-CLI will report the cross-link interference levels corresponding to multiple resources by reporting the maximum value of the measured signal and the difference value from the maximum value. For the reporting of the differential value, the relevant technology defines the differential value reporting method as shown in Table 4, and the quantization step size is 2dB.

[0057] Table 4

[0058] In Release 19 (R19), terminal devices identify one or more interfering terminal devices through SRS-RSRP measurements in the CLI, thereby avoiding scheduling them within the same or adjacent time-frequency resources. However, when one terminal device is too close to another, the SRS received power during CLI SRS-RSRP measurements may exceed the dynamic range of the receiver's ADC, preventing the receiver from detecting the SRS sequence. For subsequent scheduling and transmission, network devices need to be aware of the interference situation and the corresponding interfering terminal devices in a timely manner. For SRS that cannot be measured, a series of indications can be used to indicate that measurement is impossible. However, how to report the measurement values ​​corresponding to measurable resources is a problem that urgently needs to be solved. In particular, in dynamic SBFD and FD scenarios, in-band interference exists. Too close a distance between two terminal devices not only affects the inability to identify interfering terminal devices but, more importantly, hinders downlink reception. Therefore, choosing a timely and effective interference reporting method is crucial for future communication systems.

[0059] To address the aforementioned issues, the embodiments of this application will be described in detail below.

[0060] Figure 4 is a schematic flowchart of the communication method provided in an embodiment of this application. The method shown in Figure 4 is described from the perspective of the interaction between a terminal device and a network device, which can be the terminal device 120 and the network device 110 shown in Figure 1.

[0061] Referring to Figure 4, in step S410, the terminal device sends a measurement report of the interference signal to the network device. This interference signal can be a CLI-related interference signal or other types of interference signals.

[0062] The measurement report can be a measurement report obtained by the terminal device measuring N measurement resources (interference signal measurement). The measurement report can report M measurement values ​​(or M measurement results) from the measurement values ​​obtained from the N measurement resources. These M measurement values ​​can be a subset of the measurement values ​​corresponding to the N measurement resources. The selection criteria for these M measurement values ​​are not specifically limited in this application embodiment. In some embodiments, the largest M measurement values ​​among the measurement values ​​obtained from the N measurement resources can be reported. Alternatively, in other embodiments, the smallest M measurement values ​​among the measurement values ​​obtained from the N measurement resources can be reported (this implementation will be described in detail later with reference to specific embodiments, and will not be elaborated here).

[0063] The measurement report may include a first measured value and / or a difference between a second measured value and a first reference value. The first measured value may include SRS-RSRP and / or CLI-RSSI. In some embodiments, the measurement report may include a first measured value and one or more difference values ​​between second measured values ​​and a first reference value. That is, the first measured value may be reported using a full-information reporting method, and the second measured value may be reported using a differential reporting method. In the measurement report, the first measured value may be represented using a first bit length, and the second measured value may be represented using a second bit length, with the first bit length being greater than the second bit length. For example, the first bit length is 7, and the second bit length is 4.

[0064] The first measurement value in this measurement report can be a quantized value obtained after quantization based on a first quantization range. Taking the first quantization value as SRS-RSRP as an example, the first quantization range can be, for example, a quantization range of [-140, -44] dBm as shown in Table 3. Taking the first quantization value as CLI-RSSI as an example, the first quantization range can be, for example, a quantization range of [-100, -25] dBm.

[0065] The difference between the second measured value and the first reference value in the measurement report can be a quantized value obtained by quantization based on a second quantization range. This second quantization range can be, for example, the [-30, 0] dB quantization range shown in Table 4. Alternatively, it can be other quantization ranges, as detailed below.

[0066] As mentioned earlier, the measurement report can report partial measurement values ​​obtained from measuring N measurement resources. The measurement values ​​obtained from these N measurement resources may include one or more of the following types: Type I measurement values, Type II measurement values, and Type III measurement values. Type I measurement values ​​refer to those associated with a measurement resource that cannot be measured (e.g., the signal on the measurement resource is too strong for sequence detection; this type I measurement value could refer to SRS-RSRP, since CLI-RSSI measurement only requires an empty RE and not signal sequence detection). Type I measurement values ​​can be represented, for example, as infinity. Type II measurement values ​​refer to those outside the first quantization range (Type II measurement values ​​can be represented as out-of-range). Unlike Type I measurement values, Type II measurement values ​​are associated with measurement resources that can be detected or whose measurement values ​​can be calculated, but these Type II measurement values ​​are outside the first quantization range (Type II measurement values ​​can be SRS-RSRP or CLI-RSSI). Type III measurement values ​​refer to those whose measurement results are within the first quantization range and are considered normal measurement values. In some embodiments, the measurement report may report one or more of the following: first-type measurements, second-type measurements, and third-type measurements. For example, the measurement report may prioritize reporting first-type measurements and / or second-type measurements. Alternatively, the measurement report may prioritize reporting third-type measurements. Exemplarily, the measurement report is used to report M measurement values ​​determined from N measurement resources, where the measurement results corresponding to the N measurement resources include K first-type measurement values, and the M measurement values ​​include at least one of the K first-type measurement values. Optionally, if K is greater than or equal to M, then the M measurement values ​​are the M first-type measurement values ​​among the K first-type measurement values; and / or, if K is less than M, then the M measurement values ​​include the K first-type measurement values.

[0067] The embodiments of this application do not specifically limit the method for determining the first reference value (or the first reference point, or also the reference measurement value). Detailed examples are provided below.

[0068] In some embodiments, the measurement report is determined by measuring N measurement resources. The first reference value can be the maximum value obtained from measuring the N measurement resources. In some embodiments, if the measurement values ​​obtained from measuring the N measurement resources include a first type of measurement value (the first type of measurement value is described above and will not be detailed here), then the first reference value can be the first type of measurement value. In some embodiments, if the measurement values ​​obtained from measuring the N measurement resources include a second type of measurement value, then the first reference value can be the second type of measurement value, such as the maximum value among the second type of measurement values.

[0069] In some embodiments, the measurement report is determined by measuring N measurement resources, and the first reference value is the maximum measured value corresponding to the measurable resource among the N measurement resources. That is, the first reference value may disregard the first type of measurement values ​​mentioned above, and instead use the maximum value among the remaining measurement values ​​as the first reference value. For example, the first reference value may be the maximum value among the measured second type and third type of measurement values.

[0070] In some embodiments, the measurement report is determined by measuring N measurement resources, and the first reference value is the largest measurement value among the corresponding measurement values ​​of the N measurement resources that falls within a first quantization range (the first quantization range is described above and will not be repeated here). The first reference value is set in this way because if the reported first reference value exceeds the first quantization range, the first reference value cannot be accurately represented. Consequently, the difference value calculated based on the first reference value in the measurement report cannot be accurately represented either, resulting in the network device being unable to accurately assess the interference situation. Therefore, limiting the first reference value to the first quantization range allows for a more accurate representation of both the first reference value and the difference value obtained based on it, enabling the network device to perform reasonable scheduling.

[0071] For example, assume that the number of first-type measurement values ​​among the measurement values ​​obtained from measuring N measurement resources is K. When K is less than M (the number of measurement values ​​reported in the measurement report), the first reference value is the maximum value within the first measurement range among the remaining measurement values ​​other than the first-type measurement values ​​obtained from measuring N measurement resources. After determining the first reference value, the terminal device can report the quantized value mapped to the first reference value within the first quantization range.

[0072] In some embodiments, the first reference value is the maximum value of the second quantization range (see the previous text for an introduction to the second quantization range, which will not be repeated here).

[0073] The above text provides a detailed example of how to determine the first reference value. The following text will provide a detailed introduction to the second quantization range (the second quantization range is used to quantize the difference between the second measurement value mentioned above and the first reference value; see the previous text for details).

[0074] The two endpoints of the second quantization range correspond to the first and second values, respectively. In some embodiments, one of the first and second values ​​is 0. This indicates that the second quantization range is unidirectional, meaning it only reports measurements less than the first reference value or only reports measurements greater than the first reference value. For example, one of the first and second values ​​is 0, and the other is negative. That is, all values ​​within the second quantization range, except for the endpoints, are negative. Another example is that the first value is 0, and the second value is greater than 0. That is, all values ​​within the second quantization range, except for the endpoints, are positive. As an example, as shown in Table 4, the second quantization range is [-30, 0], and difference values ​​within this range can be accurately quantized.

[0075] In some embodiments, the first value is negative and the second value is positive. That is, the second quantization range includes both positive and negative values. In other words, the second quantization range is bidirectional, and measurements less than and greater than the first reference value can be reported. For example, the second quantization range is shown in Table 5.

[0076] Table 5

[0077] Referring to Table 5, the first value is -18, and the second value is 10. Differences within the range of [-18, 10] dB can be accurately quantized. It is understandable that if the measured value is greater than 10 or less than -18, a suitable value can also be found in the table for reporting. Note that Table 5 uses SRS-RSRP as an example only; the second quantization range can also be the quantization range for CLI-RSSI.

[0078] The second quantization range mentioned above can be determined based on protocol predefined information, preconfiguration information, and / or network device configuration information, and this application embodiment does not specifically limit this. Furthermore, the values ​​of the first and / or second values ​​mentioned above for defining the second quantization range can be determined based on protocol predefined information, preconfiguration information, and / or network device configuration information, and this application embodiment does not specifically limit this.

[0079] The second quantization range can be fixed or dynamically adjusted according to actual conditions. This application does not specifically limit the method of adjusting the second quantization range. In some embodiments, the terminal device can send first indication information to the network device. This first indication information is used to indicate the adjusted second quantization range of the terminal device. The first indication information can indicate one of the following: both endpoints of the second quantization range are less than or equal to 0; both endpoints of the second quantization range are greater than or equal to 0; one endpoint of the second quantization range is positive and the other endpoint is negative.

[0080] As a more concrete example, it can be determined, based on pre-configuration information or protocol predefined information, that both the first and second values ​​are non-zero and have opposite signs. However, in actual measurement, if there is no measurement value larger than the first reference value, the terminal device can automatically adjust the second quantization range to include only non-positive numbers. To achieve this adjustment, the terminal device can report first indication information. If the first indication information indicates 00, it means the second quantization range has not been modified; if the first indication information indicates 01, it means the second quantization range has been modified to include only non-negative numbers; if the first indication information indicates 10, it means the second quantization range has been modified to include only non-positive numbers.

[0081] In some embodiments, a new mapping relationship may be introduced into the quantization information corresponding to the second quantization range. For example, the quantization information corresponding to the second quantization range may also be used to indicate the mapping relationship between the difference value reported by the terminal device and the first type of measurement value and / or the second type of measurement value. Alternatively, the terminal device may indicate the first type of measurement value (differential infinity) and / or the second type of measurement value (differential out-of-range) by reporting the difference value. The descriptions of the first type of quantization value and the second type of quantization value can be found above and will not be detailed here.

[0082] For example, the quantization information corresponding to the second quantization range may include a first quantization value and a second quantization value, where the first quantization value may correspond to a first type of measurement value and the second quantization value may correspond to a second type of measurement value. Alternatively, in some embodiments, the quantization information corresponding to the second quantization range may include a third quantization value, which may correspond to both the first and second type of measurement values ​​simultaneously. Alternatively, the third quantization value may correspond to a measurement value outside the first quantization range (which may be a measurement value larger than the first quantization range, or a measurement value that cannot be measured).

[0083] As one possible implementation, to support the reporting of Type I measurements, a mapping relationship between quantized values ​​and Type I measurements (such as infinity) can be added to the second quantization range to indicate that the signal of certain measurement resources is too strong to be measured. When there are unmeasurable resources, if the measurement report only reports the normal measurements, the reporting results are insufficient. Reporting Type I measurements helps network devices to fully understand the interference situation and provides richer reference information for subsequent power adjustments or resource scheduling.

[0084] For example, the contents of the second quantization range can be shown in Table 6, where the quantization value DIFFRSRP_15 corresponds to the first type of measurement value, namely infinity.

[0085] Table 6

[0086] Assume that the number of first-type measurement values is K. As an alternative implementation, when 0<K<M, the terminal device may report the quantized value of the first reference value mapped within the first quantization range with a first bit length (e.g., 7 bits). For the selection method of the first reference value, reference may be made to the foregoing description, for example, the maximum value falling within the first quantization range among the measurement values may be selected. The first-type measurement values are reported with K second bit lengths (e.g., 4 bits) (e.g., DIFFRSRP_15 in the above table is reported), and the difference values between the measurement values of measurable resources and the first reference value are reported with (M-1-K) second bit lengths.

[0087] As another alternative implementation, when K is greater than M, the first-type measurement values may be reported preferentially. For example, the terminal device may report the measurement value (Infinity) of an unmeasurable measurement resource with the first bit length (e.g., 7 bits), and report the difference values (Infinity) of M-1 unmeasurable measurement resources respectively with M-1 second bit lengths (e.g., 4 bits).

[0088] As another alternative implementation, in order to support reporting of second-type measurement values, a mapping relationship between quantized values and the second-type measurement values (e.g., out-of-range) may be added in the second quantization range. In the related art, when the first reference value exceeds the first quantization range, all difference values determined based on the first reference value cannot be accurately expressed. To address this problem, adding an indication of the second-type measurement values in the second quantization range can clarify the range where the measurement value lies, thereby facilitating reasonable scheduling by the network device.

[0089] For example, the second quantization range may be as shown in Table 7 below, where DIFFRSRP_14 in the following table is exactly the quantized value corresponding to the second-type measurement value (e.g., out-of-range).

[0090] Table 7

[0091] As an alternative implementation, assuming that the first reference value may be the maximum measurement value obtained by measurement of the terminal device, when there is a second-type measurement value among the measurement values obtained by measurement of the terminal device, the terminal device reports the quantized value of the first reference value mapped in the first quantization range with the first bit length (e.g., 7 bits). If there is a measurement value smaller than the first reference value, and this measurement value is also a second-type measurement value, the difference value between this measurement value and the first reference value may be quantized according to DIFFRSRP_14 in the above table, and the remaining measurement values may be reported according to the quantized values mapped in the second quantization range based on their difference values from the first reference value.

[0092] As another optional implementation, assuming the first reference value is the maximum value within the first quantization range, the terminal device reports the quantized value mapped to the maximum measurable measurement value within the first quantization range with a first bit length (e.g., 7 bits), and reports the difference between the remaining measurement values ​​and the first reference value with a second bit length (e.g., 4 bits). When the measurement value obtained by the terminal device is greater than the first reference value, its difference value can be quantized according to DIFFRSRP_14 in the table above.

[0093] As another optional implementation, when the measurement value obtained by the terminal device includes a first type of measurement value and the number of the first type of measurement values ​​is K, when K is greater than M, the terminal device reports the first reference value Infinity with a first bit length (7 bits) and reports the difference value infinity with M-1 second bit lengths (e.g., 4 bits).

[0094] As another optional implementation, assuming the number of the first type of measurement values ​​is K, when K is less than M, optionally, the terminal device reports the maximum value Infinity with a first bit length (e.g., 7 bits), and reports the difference value Infinity with K second bit lengths (e.g., 4 bits). Let the first reference value be the maximum value within the first quantization range, then the difference between the measurement value corresponding to the measurable resource and the first reference value is reported with (M-1-K) second bit lengths (e.g., 4 bits). When the measurement value obtained by the terminal device is greater than the first reference value, its difference value can be quantized according to DIFFRSRP_14 in the table above.

[0095] As another optional implementation, let the first reference value be the maximum measurement value corresponding to the measurable resource. The terminal device reports the quantized value of the first reference value within the first quantization range with a first bit length (e.g., 7 bits), reports the difference value infinity of the first type of measurement value with K second bit lengths (e.g., 4 bits), and reports the difference value between the measurement value corresponding to the measurable resource and the first reference value with (M-1-K) second bit lengths (e.g., 4 bits). When the measurement value obtained by the terminal device is greater than the first reference value, its difference value can be quantized according to DIFFRSRP_14 in the table above.

[0096] In some embodiments, one of the two endpoints of the second quantization range (i.e., the first value and the second value) is 0, and the quantization information corresponding to the second quantization range includes the quantization value corresponding to the second type of measurement value. When the first reference value is the maximum value among the measurement values ​​obtained by the terminal device that falls within the first quantization range, if the measurement value corresponding to the measurable resource measured by the terminal device is greater than the first reference value, its difference value can be quantized according to DIFFRSRP_14 in the table above.

[0097] This application does not specifically limit the granularity of the second quantization range (i.e., the quantization granularity of the difference value). In some embodiments, the second quantization range includes a first quantization interval, the first quantization interval does not include the endpoints of the second quantization range, and the quantization step size of the first quantization interval is equal to 2dB.

[0098] In other embodiments, the second quantization range includes a first quantization interval, which does not contain the endpoints of the second quantization range, and the quantization step size of the first quantization interval is greater than 2dB. Increasing the granularity of the second quantization range can increase its coverage. The quantization step size in the second quantization range can be adjusted under certain conditions. For example, when the measured values ​​obtained by the terminal device include first-type measured values, the quantization step size of one or more quantization intervals within the second quantization range can be set to be greater than 2dB to change the quantization granularity of the difference values.

[0099] In some embodiments, the difference between the two endpoints of the second quantization range is a first difference, which is greater than 30 dB. That is, the coverage range of the two endpoints of the first quantization range can be set to be greater than 30 dB.

[0100] In some embodiments, the difference between the two endpoints of the second quantization range is a first difference, and the difference between the two endpoints of the first quantization range used to determine the first measurement value is a second difference, wherein the first difference is greater than or equal to the second difference. That is, the second quantization range can be set to be greater than or equal to the first quantization range.

[0101] For example, when the quantized value measured by the terminal device includes K first-type quantized values, if the terminal device reports a first-type measurement value (e.g., infinity) with a first bit length (e.g., 7 bits) and reports the difference value (e.g., infinity) of K-1 first-type measurement values ​​with a second bit length (e.g., 4 bits), and reports the largest MK-1 measurable measurement values ​​in the form of difference values, and the difference value is quantized with a first granularity as the quantization step size, so that it covers all or part of the range in the first quantization range.

[0102] For example, one possible implementation is that the quantization step size in the second quantization range is 6dB, and the contents of the second quantization range can be as shown in the table below.

[0103] Table 8

[0104] In related technologies, for SRS-RSRP, the first quantization range is [-140, -44] dBm, and the quantization step size of the second quantization range is 2 dB. This differential value reporting method can only cover a maximum range of 30 dB. That is, when the measured value is within the range of [-74, -44] dBm, the network device can obtain a relatively accurate measurement value, but when the measured value is less than -74 dBm, the network device has difficulty obtaining an accurate measurement value. Unlike related technologies, the embodiments of this application change the quantization step size of the second quantization range to cover the first quantization range, thereby enabling the network device to fully understand the interference situation and thus perform reasonable scheduling.

[0105] In some embodiments, the second quantization range includes a first quantization interval, the first quantization interval does not include the endpoints of the second quantization range, and the quantization step size of the first quantization interval is any value between 2dB and 6dB.

[0106] The second quantization range can be quantized using uniform quantization. That is, the quantization step size of each quantization interval within the second quantization range can be equal. For example, the quantization step size of each quantization interval within the second quantization range can be 2dB.

[0107] Alternatively, in some embodiments, the second quantization range can also be quantized using a non-uniform quantization method. For example, the second quantization range includes a second quantization interval and a third quantization interval, neither of which includes the endpoints of the second quantization range, and the quantization step sizes of the second and third quantization intervals are different. This approach can both expand the coverage of the second quantization interval and focus on changes in measurement values ​​within a small range. For example, interference signals may be related to the distribution characteristics of the terminal device, causing its measurement values ​​to be concentrated within a certain range. Therefore, the second quantization range uses a non-uniform quantization method, where a smaller quantization step size can be used within this range, and a larger quantization step size can be used outside this range.

[0108] Typically, one possible approach is to have a first granularity that includes 10dB and 2dB, with 10dB covering a larger range and 2dB focusing on the comparison of various interference signal measurements near a certain threshold or range, as shown in Table 8.

[0109] Table 8

[0110] As mentioned in some of the preceding embodiments, the terminal device can report the M largest measurement values ​​determined from the measurements of N measurement resources through a measurement report. In other embodiments, the terminal device can report the M measurement values ​​determined from the measurements of N measurement resources through a measurement report, and these M measurement values ​​include the Y smallest measurement values ​​among the measurement values ​​corresponding to the N measurement resources, where Y is a positive integer less than or equal to M.

[0111] All related technologies use the method of reporting the maximum measurement value for measurement reporting. However, in cases where there are many first-type and second-type measurements, reporting the minimum measurement value can help network devices determine the scheduling method that can reduce interference in a timely manner, thereby avoiding interference signals from hindering the reception of downlink signals.

[0112] If the measured values ​​obtained by the terminal device include the first type of measured values ​​and / or the second type of measured values, then the M measured values ​​reported by the terminal device can further include the first type of measured values ​​and / or the second type of measured values. That is, the first type of measured values ​​and / or the second type of measured values ​​are reported together with the minimum measured value, so that the network device can better understand the interference situation of the terminal device and then make reasonable scheduling.

[0113] For example, the first reference value is the smallest measured value corresponding to N measurement data. The terminal device reports the quantized value of the first reference value mapped to the first quantization range in a first bit length (e.g., 7 bits). Then, the terminal device reports the smallest M measurable measurement values ​​in the form of difference values, which can be quantized with a certain quantization step size (the quantization step size can be positive) to cover part or all of the range in the first quantization range. The terminal device can report this difference value in a second bit length (e.g., 4 bits).

[0114] For example, one possible implementation is that the quantization step size of the second quantization range can be 2dB. For example, the contents of the second quantization range can be found in Table 9.

[0115] Table 9

[0116] As an optional implementation, when the measured values ​​measured by the terminal device include a first type of measured value and the number of first type measured values ​​is K, if K is greater than M, the terminal device can report a first reference value (which can be a first type of measured value, i.e., Infinity) with a first bit length (7 bits). Then, the terminal device can report a difference value (which can be the difference value corresponding to M-1 first type of measured results, i.e., Infinity) with a second bit length of M-1 (e.g., 4 bits). When K is less than M, the terminal device can report the difference value of the first type of measured values, i.e., Infinity, with a second bit length of K (e.g., 4 bits), and report the difference value between the measured value corresponding to the measurable resource and the first reference value with a second bit length of (M-1-K) (e.g., 4 bits).

[0117] In some embodiments, the measurement report is determined by measuring N measurement resources. The measurement report also includes second indication information, which indicates measurement resources among the N measurement resources that cannot be measured and / or whose measured values ​​exceed a first quantization range. The first quantization range is used to determine the quantized value of the first measured value. For example, the measurement report may optionally include a bitmap, the length of which is the number of measurement resources measured by the terminal device. If a bit in the bitmap is set to 1, it indicates that the measurement resource corresponding to that bit cannot be measured and / or is out of range. For example, if a network device configures a terminal device to measure 8 measurement resources, and the measurement report reported by the terminal device includes a bitmap: 10000000, then the measurement resource corresponding to index #0 cannot be measured or is out of range.

[0118] In some embodiments, in addition to reporting the measured values, the measurement report may also include an index of the measurement resources corresponding to the M measured values.

[0119] In some embodiments, the measurement report is determined by measuring N measurement resources. The measurement report includes a first offset value, which indicates the offset between a third measurement value corresponding to the N measurement resources and the maximum value of a first quantization range. The first quantization range is used to quantize the first measurement value, and the third measurement value is either the maximum measurement value corresponding to the N measurement resources or the maximum measurement value corresponding to a measurable resource among the N measurement resources. Further, in some embodiments, the first reference value is the maximum value of the first quantization range.

[0120] For example, the maximum value of the first quantization range is -44dBm, and the first reference value is the maximum measurement value obtained by the terminal device. When the maximum measurement value obtained is greater than the maximum value in the first quantization range (i.e., greater than -44dBm), it can be reported as -44dB, and an additional first offset value can be reported to indicate the difference between the maximum measurement value obtained by the terminal device and the maximum value of the first quantization range, so that all values ​​are reported accurately.

[0121] The measurement values ​​mentioned in the various embodiments of this application can all be referred to as or replaced with interference signal measurement values.

[0122] It should be noted that the quantization range mentioned in the various embodiments of this application refers to a quantization range that can be accurately quantized. For example, referring to Table 4, the second quantization range refers to the quantization range of [-30, 0] dB. The last item in Table 4 (-30 ≥ ΔRSRP) only roughly maps the difference values ​​less than or equal to -30 dB to DIFFRSRP_15. This range less than or equal to -30 dB cannot be considered a range that can be accurately quantized, and therefore does not belong to the second quantization range. Accordingly, the endpoints of the quantization range mentioned in the embodiments of this application refer to the endpoints of the quantization range that can be accurately quantized. Taking Table 4 as an example again, the endpoints of the second quantization range are 0 and -30.
