[0053] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0054] To facilitate understanding of the technical solutions of the embodiments of the present application, the interference types and sensitivity fallback related to the present application are explained.

[0055] Receiver sensitivity rollback refers to a decrease in receiver sensitivity caused by interference, noise, and other factors affecting the terminal's receiver. In NR systems, there are many situations that can cause sensitivity rollback, most notably in E-UTRAN NR Dual Connectivity (EN-DC), NR E-UTRAN Dual Connectivity (NE-DC), Dual Connectivity (DC), or inter-band carrier aggregation (CA), where harmonic or intermodulation interference can cause sensitivity rollback. The following briefly describes EN-DC as an example.

[0056] Typically, intra-terminal mutual interference primarily stems from nonlinearities in RF front-end components, such as power amplifiers (PAs). When a single-tone signal, cos(wt), is input, the output signal contains higher-order harmonic components, such as 2wt and 3wt. Harmonic interference occurs when these harmonics fall within the receive frequency band. This interference often occurs when low-frequency transmission and high-frequency reception are occurring simultaneously.

[0057] When the input signal contains multiple frequency components, the output includes intermodulation products of various orders of these frequency components. For example, if the input frequency components are cos(w1t) and cos(w2t), the output will include second-order intermodulation (w1±w2) and third-order intermodulation (2w1±w2, w1±2w2). If these intermodulation products fall within the receiving frequency band, they will cause intermodulation interference. This interference often occurs in scenarios where high and low frequencies are transmitted simultaneously, or when external signals are fed back into the UE's transmit link.

[0058] Take the mutual interference between LTE's Band B3 and NR's Band n77 as an example, as shown in Figure 2. The second-order harmonic of Band B3's uplink (UL) signal will cause second-order harmonic interference on Band n77's downlink (DL) signal. The second-order intermodulation products between the Band B3 uplink signal and the Band n77 uplink signal will interfere with Band B3's downlink signal.

[0059] In NR systems, harmonic and intermodulation interference severely impacts terminal reception performance. Second harmonics and second-order intermodulation products, in particular, can significantly degrade sensitivity by tens of dB, significantly reducing the terminal's downlink reception coverage, as shown in Figure 3. A sensitivity backoff is typically defined to accommodate varying interference conditions. This is known as Maximum Sensitivity Degradation (MSD), which specifies the allowable degradation in a terminal's downlink reception capability for frequency band combinations where interference is present.

[0060] In RF design, as shown in Figure 4, the harmonics and intermodulation interference generated above can not only cause interference by reverse coupling through the terminal's transmit and receive links, but can also directly leak through the terminal's printed circuit board (PCB) into another branch, causing interference. In Figure 4, the second harmonic generated by the terminal's Band B3 transmit link interferes with 3.5 GHz reception via conduction paths and PCB leakage paths.

[0061] For interference leakage through conducted paths, filters are typically added to the RF path to suppress harmonics and intermodulation interference. For interference leakage from PCBs, additional processing, such as PCB layout and isolation, is required. However, this often depends on the terminal design, and the ultimate interference suppression performance of different terminals varies greatly.

[0062] The simultaneous transmission and reception capability of a frequency band combination refers to whether, for a frequency band combination (for example, band A and band B), band B can simultaneously receive while band A is transmitting. Typical scenarios are shown in Figures 5 and 6. Figure 5 illustrates a situation where the UL harmonics of band A affect the DL reception of band B, severely degrading reception performance. In this case, simultaneous transmission and reception of bands A and B may not be supported. Figure 6 illustrates a situation where bands A and B are transmitting simultaneously. The intermodulation signals generated by these two bands fall into the receiving band of band A, severely degrading the reception performance of band A. In this case, simultaneous transmission and reception of bands A and B may also not be supported.

[0063] In addition to the scenarios shown in Figures 5 and 6, there are other scenarios such as leakage interference from one frequency band to another due to a small frequency band spacing, which will cause the two frequency bands in a frequency band combination to be unable to transmit and receive at the same time.

[0064] When a band combination contains interference such as harmonics and intermodulation, it will result in significant sensitivity degradation, making it difficult to effectively utilize the band combination. Taking the LTE B3+NR n77 band combination in the EN-DC scenario as an example, for harmonic interference, as shown in Figure 2, the scenario is that band B3 in the band combination is transmitted while band n77 is received. The harmonic signal of the low-band B3 falls into the receiving frequency range of the high-band n77, which in turn degrades the receiving sensitivity of the high-band n77. For intermodulation signals, the intermodulation signals generated by the simultaneous transmission of bands B3 and n77 in the band combination fall into the receiving frequency range of the band combination.

[0065] Terminals can take different measures for different interference types. For example, for interference transmitted through conductive paths, terminals can suppress it by adding filters to the link or selecting a better PA to reduce the generation of nonlinear interference signals. For interference transmitted through PCBs, terminals can reduce interference by increasing isolation in the PCB design. However, these interference handling methods depend on the specific implementation of the terminal, and different terminal designs vary. Therefore, for the same frequency band combination, the actual sensitivity degradation and actual interference type caused by interference will vary among different terminals.

[0066] In some scenarios, a Mean Speed ​​Deficit (MSD) is defined for frequency band combinations with harmonic and intermodulation interference (such as B3 and NR n77), allowing terminals a certain degree of sensitivity backoff. As long as the terminal's sensitivity degradation value is less than this MSD, the requirement is considered met. However, for some frequency band combinations, the actual sensitivity backoff value is quite large. For example, when second-order harmonic interference or second-order intermodulation interference occurs, the actual sensitivity backoff value can often reach 20dB or more, as shown in Figure 2. Alternatively, in other scenarios, the terminal's sensitivity degradation value is very small. Because the base station cannot know the terminal's actual sensitivity backoff value, it can only use the defined MSD to infer the interference situation for users within the cell under this frequency band combination. In the worst case, the base station will completely avoid using this frequency band combination due to excessive interference. Therefore, how to configure frequency band combinations to balance reducing interference for terminal devices and improving band combination utilization to increase throughput is an urgent problem that needs to be solved.

[0067] FIG7 is a schematic interaction diagram of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG7 , the method 200 includes the following contents:

[0068] S210, the terminal device sends first information to the network device, where the first information is used to indicate interference information of the terminal device under a target frequency band combination, where the target frequency band combination includes at least one frequency band combination.

[0069] Correspondingly, the network device receives the first information sent by the terminal device.

[0070] In some embodiments, the interference information indicated by the first information is at the frequency band combination granularity. For example, the terminal device may report the interference information of the terminal device in each frequency band combination in the target frequency band combination to the network device.

[0071] In some embodiments, the first information is used to indicate the actual interference situation of the terminal device under the target frequency band combination, for example, the interfered frequency band under the target frequency band combination, the interfering frequency band, the actual interference intensity (for example, the actual sensitivity fallback), the interference type, etc. By reporting the actual interference situation of the terminal device under the target frequency band combination to the network device, the network device scheduling can be assisted, interference can be avoided, and throughput can be improved.

[0072] In some embodiments, the first information includes but is not limited to at least one of the following:

[0073] Interfered frequency band information in the target frequency band combination (i.e., interfered frequency band information);

[0074] Interference frequency band information in the target frequency band combination (i.e., interference frequency band information);

[0075] Interference type information under the target frequency band combination;

[0076] Interference order information under the target frequency band combination;

[0077] Interference intensity information under the target frequency band combination.

[0078] In some embodiments, interference between multiple frequency bands may exist within a frequency band combination. For example, a target frequency band combination includes a frequency band combination consisting of bands A+B+C. The interference under the target frequency band combination includes the interference of the second harmonic of band A on band B, the interference of the third harmonic of band A on band C, etc. Therefore, the interfering frequency band may include band A, and the interfered frequency band may include band B and band C. When reporting interference information, the terminal device may also report the interfered frequency band and / or the interfering frequency band information to the network device to assist the network device in understanding the interference frequency information of the terminal device and assisting the network device in configuring the frequency band combination and scheduling resources.

[0079] In some embodiments, the interference type information is used to indicate at least one of the following interference types:

[0080] Harmonic interference, intermodulation interference, out-of-band leakage interference, and harmonic mixing interference.

[0081] Taking the target frequency band combination consisting of bands A+B+C as an example, out-of-band leakage interference may include:

[0082] When the transmission frequency of band A is close to the receiving frequency of band B, the transmission of band A may interfere with the reception of band B due to insufficient isolation.

[0083] In some embodiments, the interference order information may be specific to an interference type, and each interference type may have a different interference order.

[0084] For example, for harmonic interference, the interference orders include second order, third order, fourth order, fifth order, etc., that is, harmonic interference can be second harmonic interference (twice the frequency of the transmission frequency) interference, third harmonic interference (three times the frequency of the transmission frequency) interference, fourth harmonic interference, fifth harmonic interference, etc.

[0085] For another example, intermodulation interference can have third-order, fifth-order, and other interference orders. That is, intermodulation interference can be third-order intermodulation (2*F1+ / -F2 or F1+ / -2*F2), fifth-order intermodulation (3*F1+ / -2*F2 or 2*F1+ / -3*F2 or 4*F1+ / -F2 or F1+ / -4*F2), etc. Of course, intermodulation signals also have even-order interference such as second-order intermodulation and fourth-order intermodulation.

[0086] For another example, for harmonic mixing interference, interference orders include second order, third order, fourth order, etc., that is, harmonic mixing interference can be second order harmonic mixing interference, third order harmonic mixing interference, fourth order harmonic mixing interference, etc.

[0087] For interference of different orders, there is a certain correspondence between the transmission frequency and the reception frequency. Therefore, the terminal device reports the interference order information to the network device, which can be used by the network device to determine the specific interference frequency relationship under a certain interference type.

[0088] In some embodiments, when only the interference type information is reported, the terminal device may indicate the interference type of the terminal device under the target frequency band combination through indication information. For example, the interference type indicated by the indication information may be selected from multiple candidate interference types.

[0089] Optionally, the multiple candidate interference types may be predefined or configured by the network device.

[0090] Optionally, the multiple candidate interference types may be configured through at least one of the following signaling:

[0091] Radio Resource Control (RRC) signaling, Media Access Control Control Element (MAC CE), Downlink Control Information (DCI). For example, the multiple candidate interference types may include but are not limited to some or all of the following interference types:

[0092] Harmonics, intermodulation, harmonic mixing, and out-of-band leakage interference.

[0093] In some embodiments, when both interference type information and interference order information are reported, the terminal device can indicate the interference type information and interference order information separately, or combine the indications. This application does not limit this. The specific indication method is explained below in conjunction with specific embodiments, but this application is not limited to this.

[0094] Method 1: Combined instructions, or combined reporting.

[0095] In some embodiments, the first information includes first indication information, and the first indication information is used to indicate the interference type and interference order of the terminal device under the target frequency band combination.

[0096] Mode 1-1: The interference type and interference order indicated by the first indication information are selected from a first set, where the first set includes combinations of multiple interference orders under multiple interference types.

[0097] Optionally, the first set is predefined or configured by the network device.

[0098] Optionally, the first set may be configured through at least one of the following signaling:

[0099] RRC signaling, MAC CE, DCI.

[0100] By way of example and not limitation, the first set includes some or all of the following combinations of interference types and interference orders:

[0101] Second harmonic interference, third harmonic interference, fourth harmonic interference, fifth harmonic interference, second-order intermodulation interference, third-order intermodulation interference, fourth-order intermodulation interference, fifth-order intermodulation interference, second-order harmonic mixing interference, third-order harmonic mixing interference, fourth-order harmonic mixing interference, fifth-order harmonic mixing interference, and out-of-band leakage interference.

[0102] Optionally, each combination of interference type and interference order in the first set corresponds to an index. If the index of the combination of interference type and interference order under the target frequency band combination in the first set is the first index, the first indication information is used to indicate the first index.

[0103] Mode 1-2: The interference type and interference order indicated by the first indication information are selected from multiple sets, where the multiple sets correspond to multiple interference types, and each set includes a combination of a corresponding interference type and multiple interference orders.

[0104] That is, in the embodiment of the present application, a corresponding set may be set for each interference type, and the set includes a combination of the interference type and multiple interference orders.

[0105] Optionally, the multiple sets are predefined or configured by the network device.

[0106] Optionally, the first set may be configured through at least one of the following signaling:

[0107] RRC signaling, MAC CE, DCI.

[0108] By way of example and not limitation, the plurality of sets include:

[0109] The set corresponding to the harmonic interference type, for example, {second harmonic interference, third harmonic interference, fourth harmonic interference, fifth harmonic interference}, and

[0110] A set corresponding to the intermodulation interference type, for example, {second-order intermodulation interference, third-order intermodulation interference, fourth-order intermodulation interference, fifth-order intermodulation interference}, etc.

[0111] Furthermore, when the interference type under the target frequency band combination includes harmonic interference, the terminal device can select reported information from the set corresponding to the harmonic interference.

[0112] Method 2: Give separate instructions, or report separately.

[0113] In some embodiments, the first information includes second indication information and third indication information, the second indication information is used to indicate the interference type under the target frequency band combination, and the third indication information is used to indicate the interference order under the target frequency band combination.

[0114] In some embodiments, the interference type indicated by the second indication information is selected from a second set, where the second set is a set of multiple interference types.

[0115] In some embodiments, the interference order indicated by the third indication information is selected from a third set, which is a set of multiple interference orders.

[0116] In some embodiments, the second set is predefined or configured by the network device.

[0117] Optionally, the second set may be configured through at least one of the following signaling:

[0118] RRC signaling, MAC CE, DCI.

[0119] In some embodiments, the third set is predefined or configured by the network device.

[0120] Optionally, the third set may be configured through at least one of the following signaling:

[0121] RRC signaling, MAC CE, DCI.

[0122] By way of example and not limitation, the second set includes some or all of the following interference types:

[0123] Harmonic interference, intermodulation interference, harmonic mixing interference, and out-of-band leakage interference.

[0124] By way of example and not limitation, the third set includes some or all of the following interference orders:

[0125] First order, second order, third order, fourth order, fifth order.

[0126] For example, if the interference under the target frequency band combination includes the second harmonic, the terminal device can select the harmonic interference from the second set and select the second order in the third set for reporting.

[0127] It should be noted that the out-of-band leakage interference is considered to be the interference generated by the original signal (non-frequency multiplication), so the "first-order" option is added when defining the third set. When the second set does not include out-of-band leakage interference, the third set may not include the "first-order" option.

[0128] In some embodiments, the terminal device may also report only the interference type information without reporting the interference order information. In this case, the interference order may be a default order. Optionally, the default order is the same for all interference types, or each interference type corresponds to a corresponding default order. For example, for out-of-band leakage interference, the default order may be first order, and for harmonic interference, the default order may be second order.

[0129] In some embodiments, the interference intensity information under the target frequency band combination is used to characterize the degree of interference of the terminal device under the target frequency band combination. Optionally, the interference intensity information can be characterized by sensitivity fallback, or other relevant parameters, which are not limited in this application.

[0130] In some embodiments, the interference intensity information under the target frequency band combination may include actual MSD information of the terminal device under the target frequency band combination.

[0131] It should be understood that in an embodiment of the present application, the terminal device can directly report the interference intensity value under the target frequency band combination to the network device, or it can also report the quantized value of the interference intensity value, for example, quantizing the interference intensity value into an interval and reporting the interval to which the interference intensity value belongs.

[0132] In some embodiments, the first information includes fourth indication information, and the fourth indication information is used to indicate a target interference intensity interval, where the target interference intensity interval is selected from a plurality of interference intensity intervals, and the target interference intensity interval is the interval to which the interference intensity information under the target frequency band combination belongs.

[0133] That is, the terminal device may determine the interference intensity interval to which the interference intensity under the target frequency band combination belongs, and further report the interference intensity interval to which the interference intensity belongs to to the network device.

[0134] Optionally, the multiple interference intensity intervals may be multiple MSD intervals, and the target interference intensity interval may be a target MSD interval.

[0135] In some embodiments, the fourth indication information is used to indicate a target interference intensity interval, and the target interference intensity interval corresponds to all interference types reported by the terminal device.

[0136] In this case, the target interference intensity interval is obtained by the terminal device for all reported interference types.

[0137] For example, the terminal device can measure the interference of all reported interference types to obtain an MSD value. Further, the terminal device can determine the target MSD interval to which the MSD value belongs among multiple MSD intervals, and then report the target MSD interval to the network device.

[0138] In one implementation, the terminal device may sum the interference intensities measured for each interference type among all interference types to obtain a total interference intensity value, and then determine the MSD values ​​corresponding to the interference of all interference types based on the total interference intensity value and the noise floor. For example, the MSD values ​​corresponding to the interference of all interference types may be obtained by taking the difference between the total interference intensity value and the noise floor.

[0139] In another implementation, the terminal device may sum the interference intensities measured for each interference type among all interference types to obtain a total interference intensity value, determine a sensitivity value corresponding to the total interference intensity value, and then determine the MSD values ​​corresponding to interference of all interference types based on the sensitivity value corresponding to the total interference intensity value and the sensitivity value in the case of only background noise. For example, the MSD values ​​corresponding to interference of all interference types may be obtained by taking the difference between the sensitivity value corresponding to the total interference intensity value and the sensitivity value in the case of only background noise.

[0140] In other embodiments, the fourth indication information is used to indicate at least one target interference intensity interval, wherein each target interference intensity interval corresponds to an interference type, each interference type corresponds to multiple interference intensity intervals, and each target interference intensity interval is selected from multiple interference intensity intervals of the corresponding interference type.

[0141] That is, the terminal device may determine the interference intensity interval to which the reported interference intensity information of each interference type belongs.

[0142] In this case, the target interference intensity interval may be determined based on the interference situation of the corresponding interference type.

[0143] For example, the terminal device can measure the interference of each reported interference type to obtain the MSD value corresponding to each interference type. Furthermore, the terminal device can determine the target MSD interval to which the MSD value belongs among the multiple MSD intervals corresponding to the interference type, and then report the target MSD interval corresponding to the interference type to the network device.

[0144] In one implementation, the terminal device may determine the MSD value corresponding to each interference type based on the interference strength and noise floor measured for each interference type. For example, the MSD value corresponding to each interference type is obtained by taking the difference between the interference strength and noise floor measured for each interference type.

[0145] In another implementation, the terminal device may determine a sensitivity value corresponding to each interference type based on the interference intensity measured for each interference type, and then determine an MSD corresponding to each interference type based on the sensitivity value corresponding to each interference type and the sensitivity value in a case where only background noise is present. For example, the MSD value corresponding to each interference type is obtained by taking the difference between the sensitivity value corresponding to each interference type and the sensitivity value in a case where only background noise is present.

[0146] In some embodiments, the multiple interference intensity intervals are predefined or configured by the network device.

[0147] Optionally, the multiple interference strength intervals may be configured through at least one of the following signaling:

[0148] RRC signaling, MAC CE, DCI.

[0149] In some embodiments, the plurality of interference intensity intervals are determined according to one or more thresholds.

[0150] In some embodiments, the one or more thresholds are predefined or configured by the network device.

[0151] That is, the network device can configure multiple interference intensity intervals or one or more thresholds for the terminal device.

[0152] Optionally, the one or more may be configured through at least one of the following signaling:

[0153] RRC signaling, MAC CE, DCI.

[0154] In some embodiments, the value of the first indication information indicates the interference intensity interval to which the interference intensity information belongs.

[0155] Optionally, the first indication information may include N bits, where the size of N may be determined based on the number of multiple interference intensity intervals. For example, if there are four interference intensity intervals, the first indication information may include two bits. Different values ​​of the two bits are used to indicate different interference intensity intervals. For example, a value of 00 indicates the first interference intensity interval, 01 indicates the second interference intensity interval, 10 indicates the third interference intensity interval, and 11 indicates the fourth interference intensity interval.

[0156] In some other embodiments, the interference intensity interval to which the interference intensity information belongs is indicated by a bitmap.

[0157] For example, the first indication information may be M bits, where M is the number of multiple interference intensity intervals. Each bit in the M bits corresponds to an interference intensity interval, and the value of each bit is used to indicate whether the corresponding interference intensity interval is a target interference intensity interval. For example, if there are 4 interference intensity intervals, the first indication information may include 4 bits. The 4 bits correspond to 4 interference intensity intervals. For example, if the bit value is 1, it indicates that the corresponding interference intensity interval is a target interference intensity interval, otherwise it indicates that the corresponding interference intensity interval is not a target interference intensity interval.

[0158] For example, the multiple interference intensity intervals are MSD intervals, for example, including the following four intervals:

[0159] 0≤Sensitivity fallback<5dB, 5≤Sensitivity fallback<10dB, 10≤Sensitivity fallback<15dB, 15≤Sensitivity fallback<20dB.

[0160] If the actual interference strength of the terminal device under the target frequency band combination is 2dB, the first indication information can indicate 2dB or the first interval. If the actual interference strength of the terminal device under the target frequency band combination is 18dB, the first indication information can indicate 18dB or the fourth interval.

[0161] Taking the target frequency band combination including the frequency band combination consisting of band A+B+C as an example, the content of the first information reported by the terminal device is explained, for example, including part or all of the information in Table 1.

[0162] Table 1

[0163]

[0164] Here, XdB represents the actual interference intensity under the target frequency band combination, such as the actual MSD value.

[0165] In some embodiments, when the interference intensity under the target frequency band combination is relatively low, the terminal device reports the interference intensity information under the target frequency band combination. In this case, the interference intensity information can be considered as low interference indication information.

[0166] In some embodiments, for a frequency band combination, if a terminal device has low interference in a frequency band combination, it can be considered that the terminal device also has low interference in a frequency band combination composed of sub-bands in the frequency band combination.

[0167] For example, for the target frequency band combination consisting of three frequency bands A+B+C, when the terminal device reports the low interference indication information, it is considered that the interference of the terminal device under the frequency band combination A+B, frequency band combination B+C, frequency band combination A+C, etc. (low-order frequency band combinations) composed of the two sub-bands in the target frequency band combination is also low, that is, the low interference indication information is also applicable to the frequency band combination A+B, frequency band combination B+C, frequency band combination A+C, etc. (low-order frequency band combinations).

[0168] For another example, for a target frequency band combination consisting of three frequency bands A+B+C, if the terminal device reports the interference type as second harmonic, the interfered frequency band is B, the interfering frequency band is A, and the reported interference strength information is in one of the four intervals, and the terminal device's MSD is located in one of the four intervals, the second harmonic interference is considered low. Correspondingly, for a frequency band combination consisting only of frequency bands A+B, the second harmonic interference can also be considered low.

[0169] For another example, for a target band combination consisting of three bands A+B+C, if the interference type reported by the terminal device is intermodulation interference, the interference order is second-order, the interfered band is C, and the interfering bands are bands A and B, that is, the intermodulation interference is the second-order intermodulation of bands A and B on band C. Furthermore, the reported interference strength information is in one of the four intervals mentioned above. When the terminal device's MSD is located in one of the four spaces, the intermodulation interference is considered low. Correspondingly, for band combinations consisting only of bands A+B, bands A+C, and bands B+C, the second-order intermodulation can also be considered low interference.

[0170] In other embodiments, when the interference intensity under the target frequency band combination is relatively high, the terminal device reports the interference intensity information under the target frequency band combination. In this case, the interference intensity information can be considered as high interference indication information.

[0171] In some embodiments, the target frequency band combination is a frequency band combination that satisfies a first condition among multiple frequency band combinations of the terminal device. For example, the terminal device may select multiple frequency band combinations and further report interference information of the terminal device under the frequency band combination that satisfies the condition.

[0172] Optionally, the frequency band combination meeting the first condition indicates that the terminal device experiences greater interference in the frequency band combination, that is, the terminal device may only report interference information of the terminal device in the frequency band combination with greater interference.

[0173] Optionally, if the interference intensity information of the terminal device under the frequency band combination is greater than the first threshold, or the interference intensity information is greater than or equal to the first threshold, it can be considered that the frequency band combination meets the first condition.

[0174] That is, the first threshold can be used by the terminal device to select which frequency band combination to report interference information.

[0175] In some embodiments, the first threshold is a first MSD threshold.

[0176] In some embodiments, the first threshold is predefined or configured by the network device.

[0177] Optionally, the first threshold may be configured through at least one of the following signaling:

[0178] RRC signaling, MAC CE, DCI.

[0179] In some embodiments, the first threshold is granular per interference type.

[0180] That is, for each interference type, a corresponding threshold for selecting a frequency band combination to be reported may be predefined or configured by the network device.

[0181] In this case, the terminal device can determine whether to report the interference intensity information corresponding to the interference type under the frequency band combination based on the interference intensity information under each interference type and the corresponding first threshold.

[0182] In some other embodiments, the first threshold is for all interference types, that is, the first threshold does not distinguish between interference types.

[0183] In this case, the terminal device may determine whether to report the interference intensity information corresponding to all interference types based on the interference intensity information of all interference types and the first threshold.

[0184] For example, if the actual MSD of the terminal device in the frequency band combination consisting of frequency band A and frequency band B is 2dB, and the actual MSD of the terminal device in the frequency band combination consisting of frequency band C and frequency band D is 30dBm, the first threshold is 25dB, that is, the MSD in the frequency band combination consisting of frequency band C and frequency band D meets the first threshold, then the terminal device can report the interference information in the frequency band combination consisting of frequency band C and frequency band D, and does not report the interference information in the frequency band combination consisting of frequency band A and frequency band B, that is, the terminal device only reports the interference information in the frequency band combination with greater interference.

[0185] In some other embodiments, the target frequency band combination is a frequency band combination that meets the second condition among multiple frequency band combinations of the terminal device.

[0186] Optionally, the frequency band combination meeting the second condition indicates that the terminal device experiences less interference in the frequency band combination, that is, the terminal device may only report interference information of the terminal device in the frequency band combination with less interference.

[0187] Optionally, when the interference intensity information under the frequency band combination is less than the second threshold, it can be considered that the frequency band combination meets the second condition.

[0188] That is, the second threshold can be used by the terminal device to select which frequency band combination to report interference information.

[0189] In some embodiments, the second threshold is a second MSD threshold.

[0190] In some embodiments, the second threshold is predefined or configured by the network device.

[0191] Optionally, the second threshold may be configured through at least one of the following signaling:

[0192] RRC signaling, MAC CE, DCI.

[0193] In some embodiments, the second threshold is granular per interference type.

[0194] That is, for each interference type, a corresponding threshold for selecting a frequency band combination to be reported may be predefined or configured by the network device.

[0195] In this case, the terminal device may determine whether to report the interference intensity information corresponding to the interference type under the frequency band combination based on the interference intensity information under each interference type and the corresponding second threshold.

[0196] In some other embodiments, the second threshold is for all interference types, that is, the second threshold does not distinguish between interference types.

[0197] In this case, the terminal device may determine whether to report the interference intensity information corresponding to all interference types based on the interference intensity information of all interference types and the second threshold.

[0198] For example, if the actual MSD of the terminal device in the frequency band combination consisting of frequency band A and frequency band B is 2dB, and the actual MSD of the terminal device in the frequency band combination consisting of frequency band C and frequency band D is 30dBm, the second threshold is 5dB, that is, the MSD in the frequency band combination consisting of frequency band A and frequency band B meets the second threshold, then the terminal device can report the interference information in the frequency band combination consisting of frequency band A and frequency band B, and not report the interference information in the frequency band combination consisting of frequency band C and frequency band D, that is, the terminal device only reports the interference information in the frequency band combination with less interference.

[0199] In some embodiments, the terminal device determines a candidate frequency band combination for reporting interference information based on the MSD of the allowed terminal device and a third MSD threshold.

[0200] Optionally, the MSD of the allowed terminal devices is at a granularity of per frequency band combination.

[0201] That is, each frequency band combination may correspond to a corresponding allowed MSD.

[0202] In this case, the terminal device can determine whether to report the interference information under each frequency band combination based on the MSD corresponding to the frequency band combination and the third MSD threshold. For example, if the MSD corresponding to the frequency band combination is greater than or equal to the third MSD threshold, the frequency band combination is determined to be a candidate frequency band combination for reporting interference information. Otherwise, the interference information under the frequency band combination is not reported.

[0203] That is to say, when the MSD of the allowed terminal device is relatively large, the terminal device reports the actual interference situation under the frequency band combination to the network device. When the MSD of the allowed terminal device is relatively small, since the actual MSD of the terminal device needs to meet the MSD indicator of the allowed terminal device, the actual MSD of the terminal device will be smaller than the MSD indicator of the allowed terminal device. Therefore, the terminal device does not need to report the actual interference situation under the frequency band combination, which is beneficial to reducing the signaling overhead of the terminal device.

[0204] Optionally, the MSD of the allowed terminal devices is granular per interference type.

[0205] Optionally, the third MSD threshold is predefined or configured by the network device.

[0206] Optionally, the third MSD threshold may be configured through at least one of the following signaling:

[0207] RRC signaling, MAC CE, DCI.

[0208] Optionally, the third MSD threshold is for all interference types, that is, the third MSD threshold does not distinguish between interference types.

[0209] Optionally, the third MSD threshold is granular for each interference type, that is, the third MSD threshold distinguishes interference types.

[0210] In one specific implementation, the terminal device may first determine a candidate frequency band combination for reporting interference information based on the MSD corresponding to the frequency band combination and the third MSD threshold. For example, if the MSD corresponding to the frequency band combination is greater than or equal to the third MSD threshold, the frequency band combination is determined to be a candidate frequency band combination for reporting interference information.

[0211] Furthermore, the target frequency band combination may be determined from the candidate frequency band combinations according to the first threshold or the second threshold.

[0212] For example, a frequency band combination whose interference strength information is greater than a first threshold among candidate frequency band combinations is determined as a target frequency band combination, or a frequency band combination whose interference strength information is less than a second threshold among candidate frequency band combinations is determined as a target frequency band combination.

[0213] In another specific implementation manner, the terminal device may directly determine the target frequency band combination from a plurality of frequency band combinations of the terminal device according to the first threshold or the second threshold.

[0214] For example, a frequency band combination whose interference strength information is greater than a first threshold is determined as a target frequency band combination, or a frequency band combination whose interference strength information is less than a second threshold is determined as a target frequency band combination.

[0215] In another specific implementation, the terminal device may determine a target frequency band combination for reporting interference information based on the MSD corresponding to the frequency band combination and a third MSD threshold. For example, if the MSD corresponding to the frequency band combination is greater than or equal to the third MSD threshold, the frequency band combination is determined to be the target frequency band combination for reporting interference information.

[0216] In some embodiments of the present application, the first information is reported autonomously by the terminal device. For example, the terminal device reports the interference information under the frequency band combination according to the actual interference situation.

[0217] For example, the terminal device may select a frequency band combination that meets the reporting conditions according to the aforementioned first threshold or second threshold, and further report the interference information of the terminal device under the frequency band combination.

[0218] In some embodiments, the terminal device may report the first information to the network device during the random access process.

[0219] For example, the first information is reported to the network device through message 1 (Msg1) or message 3 (Msg3) in the random access process.

[0220] In other embodiments of the present application, the terminal device may report the first information to the network device based on a request or inquiry from the network device.

[0221] For example, the terminal device may receive inquiry information sent by the network device, and further send first information to the network device based on the inquiry information of the network device, where the inquiry information is used to inquire about interference information of the terminal device under at least one frequency band combination.

[0222] In some embodiments, the network device queries the terminal device for information that is helpful for the scheduling of the network device by querying information.

[0223] Optionally, the inquiry information may be used to indicate at least one of information of a frequency band combination inquired by the network device, a type of interference information inquired (ie, which interference information is reported), and a reporting threshold of the interference information.

[0224] In some embodiments, the query information includes but is not limited to at least one of the following:

[0225] Information of at least one frequency band combination, interference type information, interference order information, interference intensity information, and a reporting threshold for interference intensity information.

[0226] Optionally, the reporting threshold may be the first threshold or the second threshold mentioned above.

[0227] That is, the network device inquires the terminal device about the interference information under the frequency band combination with greater interference (for example, the interference intensity is greater than the first threshold), or inquires the terminal device about the interference information under the frequency band combination with less interference (for example, the interference intensity is less than the second threshold).

[0228] Optionally, the at least one frequency band combination is a frequency band combination that the network device wants to inquire about, that is, the network device wants to obtain interference information of the terminal device under the at least one frequency band combination.

[0229] Optionally, the interference type information may be interference type information that the network device wants to obtain, or the network device requires the terminal device to carry the interference type information in the first information.

[0230] Optionally, the interference order information may be interference order information that the network device wants to obtain, or the network device requires the terminal device to carry the interference order information in the first information.

[0231] Optionally, the interference order information may be interference order information that the network device wants to obtain, or the network device requires the terminal device to carry the interference order information in the first information.

[0232] In some embodiments, some of the information in the query information may be predefined. For example, the interference type may be predefined, such as querying for harmonic interference by default. Another example may be predefined, such as querying for second-order interference by default. Another example may be predefined, such as querying for reporting thresholds by default.

[0233] In some embodiments, the target frequency band combination is a frequency band combination whose interference intensity information meets a reporting threshold among at least one frequency band combination queried by the network device.

[0234] In some embodiments of the present application, the method 200 further includes:

[0235] S220: The network device performs frequency band combination configuration and / or simultaneous transmission and reception configuration of frequency bands in the frequency band combination according to the first information.

[0236] In some embodiments, after receiving the first information reported by the terminal device, the network device may determine a frequency band combination with low interference. For the frequency band combination with low interference, the network device may configure the frequency band combination for the terminal device, or may not configure the frequency band combination, or may schedule resources on the frequency band combination during scheduling, or may avoid scheduling resources on the frequency band combination.

[0237] In some embodiments, after receiving the first information reported by the terminal device, the network device may determine a frequency band combination with high interference. For a frequency band combination with high interference, the network device may not configure the frequency band combination for the terminal device, or avoid scheduling resources on the frequency band combination during scheduling.

[0238] In some embodiments, for frequency band combinations with high interference, the network device may take certain measures to avoid interference.

[0239] For example, for a frequency band combination consisting of frequency band A and frequency band B, where frequency band A has harmonic interference with frequency band B, one way to avoid interference is to prevent frequency band A and frequency band B from being in a state of one transmitting and one receiving (i.e., simultaneous transmitting and receiving) during scheduling.

[0240] For example, for a frequency band combination consisting of band A, band B, and band C, the intermodulation information between band A and band B interferes with band C. In this case, the network equipment can avoid intermodulation interference with band C by transmitting band A and band B at different times.

[0241] In summary, the terminal device can report the interference information of the terminal device under the target frequency band combination to the network device, so that the network device can perform frequency band combination configuration and / or simultaneous transmission and reception configuration of the frequency bands in the target frequency band combination based on the interference information under the target frequency band combination reported by the terminal device, which is beneficial to both reducing the interference of the terminal device and improving the throughput.

[0242] For example, for frequency band combinations with greater interference, network equipment can avoid configuring the frequency band combination for terminal devices, or avoid scheduling resources on the frequency band combination during scheduling, or avoid configuring the frequency bands in the frequency band combination to be in a simultaneous transmit and receive state, which is beneficial to reducing interference to terminal devices.

[0243] For another example, for a frequency band combination with less interference, the network device can configure the frequency band combination for the terminal device, or the scheduling can use the resources on the frequency band combination, which is conducive to improving throughput.
