Description

[Technical Field]

[0001] The present disclosure relates to the field of communication technologies, and in particular to an interference information reporting method, a frequency range determining method, an interference information reporting device, a frequency range determining device, a communication device, and a computer-readable storage medium. [Background technology]

[0002] Due to different network and service needs, the same User Equipment (UE) may be equipped with a variety of different radio transceivers, such as those for 4G LTE, 5G NR, Wireless Fidelity (WIFI), Bluetooth, and Global Navigation Satellite System (GNSS) radio access technologies (RATs).

[0003] The frequency at which a signal is received by a radio receiver and the frequency at which a signal is transmitted by a radio transmitter may overlap, for example, the frequency at which the signal is received and the frequency at which the signal is transmitted may be adjacent or at harmonic frequency portions, and the radio receiver may experience interference from the transmitter.

[0004] Furthermore, the UE can report the existing interference problem to the base station so that the base station can provide a solution to the UE. Currently, the information that the UE reports to the base station about the interference problem includes the center frequency point of the interfered area, for example, the absolute radio frequency channel number (ARFCN), and the frequency corresponding to the ARFCN is the center frequency point.

[0005] Because the information reported by the UE regarding the interference problem only includes the center frequency point, the base station can only determine that this center frequency point in one frequency band is interfered with based on this. If other frequencies in this frequency band are interfered with, the base station will not be able to accurately determine the frequency range that is interfered with based only on the center frequency point reported by the UE. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of this, embodiments of the present disclosure provide an interference information reporting method, a frequency range determination method, an interference information reporting device, a frequency range determination device, a communication device, and a computer-readable storage medium to solve the technical problems in the related art. [Means for solving the problem]

[0007] According to a first aspect of an embodiment of the present disclosure, there is provided an interference information reporting method applied to a terminal, the method including: a step of determining that a condition for transmitting interference information is met; and a step of transmitting the interference information to a network device, the interference information including information of a frequency range related to a frequency interference problem.

[0011] According to a fifth aspect of an embodiment of the present disclosure, there is provided a communication device including a processor and a memory for storing a computer program, which, when executed by the processor, realizes the above-mentioned interference information reporting method.

[0012] According to a sixth aspect of an embodiment of the present disclosure, there is provided a communication device including a processor and a memory for storing a computer program, the computer program realizing the above-mentioned frequency range determination method when executed by the processor.

[0014] According to an eighth aspect of the present disclosure, there is provided a computer-readable storage medium having a computer program stored thereon, the computer program implementing the steps of the above-described frequency range determination method when executed by a processor.

[0016] Because the interference information reported by the terminal to the network device includes information on the frequency range related to the frequency interference problem, as opposed to the reported interference information including only the center frequency point, it becomes easier for the network device to accurately determine the frequency range in which the interference occurs, and further makes it easier for the network device to accurately resolve the frequency interference problem.

[0018] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure, but it is clear that the described embodiments are only some of the embodiments of the present disclosure, rather than all of the embodiments, and all other embodiments that can be obtained by a person skilled in the art based on the embodiments of the present disclosure without any creative effort fall within the scope of protection of the present disclosure.

[0019] Terms used in the embodiments of the present disclosure are merely for the purpose of describing particular embodiments and are not intended to limit the embodiments of the present disclosure.

Note that the term "and / or," as used herein, refers to any and all possible combinations of one or more of the associated listed items.

[0020] In embodiments of the present disclosure, terms such as first, second, and third may be used to describe various pieces of information, but it should be understood that such information should not be limited to these terms. These terms are merely used to distinguish between pieces of information of the same type. For example, first information can be referred to as second information, and similarly, second information can be referred to as first information, without departing from the scope of embodiments of the present disclosure. Depending on the context, the word "if" used herein can be interpreted as "when" or "in the case of" or "in response to determining."

[0021] For simplicity and ease of understanding, the terms "greater than" or "smaller," "higher than" or "lower" are used herein when characterizing magnitude relationships. However, one of ordinary skill in the art will understand that the term "greater than" also means "greater than or equal to," the term "smaller" also means "less than or equal to," and the term "higher" also means "more than or equal to," and the term "lower" also means "less than or equal to."

[0022] 1 is a schematic flowchart of an interference information reporting method according to an embodiment of the present disclosure. The interference information reporting method according to this embodiment can be applied to a terminal, which includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with a network device (e.g., user equipment), which includes, but is not limited to, network devices such as base stations and core networks in communication systems such as 4G, 5G, and 6G.

[0023] As shown in FIG. 1, the interference information reporting method may include the following steps S101 to S102.

[0024] In step S101, it is determined that the conditions for transmitting interference information are met.

[0025] In step S102, transmit interference information to a network device, where the interference information includes information on frequency ranges related to frequency interference problems.

[0026] In one embodiment, the frequency interference problem includes, but is not limited to, interference between a wireless receiver and a wireless transmitter in a terminal, such as In-Device Coexistence (IDC) interference.

[0027] In one embodiment, when a condition for transmitting interference information is met, the terminal transmits interference information to the network device, thereby instructing the network device on information of a frequency range related to the frequency interference problem so that the network device can determine the frequency range related to the frequency interference problem.

[0028] Because the interference information reported by the terminal to the network device includes information on the frequency range related to the frequency interference problem, as opposed to the reported interference information including only the center frequency point, it becomes easier for the network device to accurately determine the frequency range in which the interference occurs, and further makes it easier for the network device to accurately resolve the frequency interference problem.

[0029] For example, for frequency band A, the start frequency is f1, the end frequency is f2, and the center frequency point is (f1+f2) / 2. If a frequency interference problem occurs within the frequency range of f3 to f4 in frequency band A, and the frequency of f1 <f3<f4<(f1+f2) / 2である。

[0030] If the terminal instructs the network device only about the center frequency point, the network device can only determine that the frequency interference problem occurs near (f1+f2) / 2. However, since the frequency interference problem actually occurs within the frequency range of f3 to f4, the network device cannot accurately determine the frequency range in frequency band A where the frequency interference problem occurs based on the interference information reported by the terminal.

[0031] A method for a network device to solve the frequency interference problem is to instruct a terminal to suspend communication using a frequency around (f1+f2) / 2, but since a frequency interference problem occurs in the frequency range of f3 to f4, even if the terminal suspends use of a frequency around (f1+f2) / 2, the terminal still communicates using a frequency within the frequency range of f3 to f4, and the frequency interference problem still exists. In this case, the network device will not be able to accurately solve the frequency interference problem for the terminal.

[0032] However, according to this embodiment, among the interference information reported by the terminal to the network device, the frequency range information related to the frequency interference problem may be f3 to f4, so that the network device can accurately determine that the frequency interference problem has occurred within the frequency range of f3 to f4 in frequency band A.

[0033] A method for the network device to solve the frequency interference problem may be to instruct the terminal to suspend communication using frequencies within the f3-f4 frequency range, and when a frequency interference problem occurs in the f3-f4 frequency range, the terminal suspends communication using frequencies within the f3-f4 frequency range, thereby avoiding the frequency interference problem. As can be seen from the above, the network device can accurately solve the frequency interference problem for the terminal.

[0034] The method by which the network device solves the frequency interference problem for the terminal is not limited to instructing the terminal to suspend communication within the frequency range where the frequency interference problem occurs, and other methods may be selected as needed, for example, the network device itself suspends transmitting downlink information to the terminal within this frequency range.

[0035] The manner in which the terminal transmits interference information to the network device can be configured as needed, and may be, for example, transmitted by Radio Resource Control (RRC) signaling, by physical layer information, or in a random access process, and is not limited by the present disclosure.

[0036] In one embodiment, the condition is: The frequency interference problem has occurred, the frequency interference problem has ceased; and the occurrence of new frequency interference problems.

[0037] In one embodiment, when a frequency interference problem occurs, the terminal may transmit interference information to the network device, which may allow the network device to determine that a frequency interference problem has occurred for the terminal within a frequency range related to the frequency interference problem, thereby resolving the frequency interference problem for the terminal, such as by instructing the terminal to suspend communication using frequencies within the frequency range.

[0038] In one embodiment, when the frequency interference problem that occurred has stopped, the terminal may transmit interference information to the network device, which may cause the network device to determine that the frequency interference problem that occurred within the frequency range has stopped, and further release the restriction on the terminal for solving the frequency interference problem, for example, instructing the terminal to continue to communicate using frequencies within the frequency range.

[0039] In one embodiment, when a new frequency interference problem occurs, the terminal can transmit interference information to the network device, and the interference information can include information on a frequency range related to the new frequency interference problem, so that the network device can determine that a frequency interference problem has occurred for the terminal in the new frequency range related to the new frequency interference problem, thereby resolving the frequency interference problem for the terminal, such as by instructing the terminal to suspend communication using frequencies in the new frequency range.

[0040] In one embodiment, the frequency range information is The frequency range in which the interference occurs, and and a combination of frequency ranges in which interference occurs. The frequency range in which interference occurs includes at least one of a frequency range that causes interference and a frequency range that is subject to interference.

[0041] In one embodiment, the frequency interference problem occurring in the terminal may be interference between two frequency ranges, such as frequency range #1 causing interference to frequency range #2, and the terminal can report the frequency range in which the interference occurs to the network device, for example, reporting at least one of the two frequency ranges, frequency range #1 and frequency range #2, and indicating the frequency range causing interference and the frequency range that is interfered with among the reported frequency ranges.

[0042] In addition, the frequency interference problem that has occurred may be interference occurring between at least one pair of frequency ranges, or may be interference occurring between multiple pairs of frequency ranges, and the terminal may report multiple pairs of frequency ranges and indicate the relationship between the reported frequency ranges.

[0043] For example, a terminal may simultaneously experience interference from frequency range #1 on frequency range #2 and interference from frequency range #3 on frequency range #4. The frequency ranges reported by the terminal where interference occurs may include frequency range #1, frequency range #2, frequency range #3, and frequency range #4, indicating that frequency range #1 and frequency range #3 are the frequency ranges causing interference, frequency range #2 and frequency range #4 are the frequency ranges affected by interference, frequency range #1 corresponds to frequency range #2, and frequency range #3 corresponds to frequency range #4. This allows the network device to determine that frequency range #1 causes interference on frequency range #2 and frequency range #3 causes interference on frequency range #4.

[0044] In one embodiment, a frequency interference problem occurring at a terminal may be caused by a common effect (including but not limited to cross-modulation) of two or more frequency ranges causing interference in another frequency range, and the terminal may report to the network device the combination of frequency ranges in which the interference occurred, for example, the combination of frequency ranges in which the interference occurred due to the common effect.

[0045] For example, if the common effect of frequency range #5 and frequency range #6 causes interference to frequency range #7, the terminal can report the frequency range combination consisting of frequency range #5 and frequency range #6 to the network device, and can also report frequency range #7 to the network device. This allows the network device to determine that the common effect of frequency range #5 and frequency range #6 causes interference to frequency range #7. The type of common effect, such as cross-modulation, can also be instructed to the network device.

[0046] In one embodiment, the combination of frequency ranges comprises a plurality of frequency ranges and / or frequencies, i.e. the combination of frequency ranges comprises at least one frequency range.

[0047] For example, the combination of frequency ranges may include frequency range #1 and frequency #2, where frequency range #1 is a frequency range with a bandwidth of 20 MHz centered on a frequency corresponding to absolute radio frequency channel number ARFCN-1, and frequency #2 is a frequency corresponding to ARFCN-2; Alternatively, the combination of frequency ranges may include frequency range #1 and frequency range #2, where frequency range #1 is a frequency range with a center frequency point at the frequency corresponding to ARFCN-1 and a bandwidth of 20 MHz, and frequency range #2 is a frequency range with a center frequency point at the frequency corresponding to ARFCN-2 and a bandwidth of 20 MHz.

[0048] In one embodiment, the interference information further includes the radio access technology corresponding to the frequency range in which the interference occurs in the interference problem.

[0049] In one embodiment, the radio access technology is: Third Generation Partnership Project (3GPP) radio access technologies, such as LTE (Long Term Evolution) and NR (New Radio), Global Positioning System (GPS) and Beidou System (BDS) and Global Navigation Satellite System (GNSS) and Wireless Local Area Network (WLAN) and Galileo Positioning System (Galileo) and IRNSS (Indian Regional Navigation Satellite System) and Bluetooth BT (Bluetooth) and at least one of them.

[0050] The radio access technology corresponding to the frequency range where interference occurs, carried in the interference information, includes the radio access technology of the frequency range causing interference and / or the radio access technology of the frequency range affected by interference, for example, the radio access technology of the frequency range causing interference is WLAN and the frequency range affected by interference is NR. This allows the network device to accurately determine the radio access technology corresponding to the frequency range where interference occurs, and avoids the difficulty of the network device in distinguishing the radio access technology corresponding to the frequency range when there is overlap between frequency ranges included in different radio access technologies by reporting only the frequency range. This is advantageous in ensuring that the network device accurately solves frequency interference problems for the terminal based on the radio access technology corresponding to the frequency range.

[0051] In one embodiment, the type of frequency range information is: a center frequency point number and bandwidth information associated with said center frequency point number; A start frequency point number and an end frequency point number, Bandwidth fraction information; Cell information, Cell group information; and measurement object information.

[0052] In one embodiment, the type of frequency range information that the terminal reports to the network device can be selected as needed.

[0053] In one embodiment, a center frequency point number and bandwidth information associated with the center frequency point number may be reported, and the center frequency point number may be characterized by an absolute radio frequency channel number ARFCN. For example, the reported center frequency point number is ARFCN-1 and the corresponding bandwidth information is 20M, allowing the network device to determine that the frequency range is from the frequency corresponding to ARFCN-1 minus 10M to the frequency corresponding to ARFCN-1 plus 10M.

[0054] In one embodiment, a start frequency point number and an end frequency point number can be reported, and the start frequency point number and the end frequency point number can be characterized by an absolute radio frequency channel number ARFCN. For example, the reported start frequency point number is ARFCN-1 and the end frequency point number is ARFCN-2, and the network device can thereby determine that the frequency range is from the frequency corresponding to ARFCN-1 to the frequency corresponding to ARFCN-2.

[0055] In one embodiment, bandwidth part (BWP) information such as a BWP identifier (number) is reported, and the network device can determine the corresponding BWP based on the BWP information, and then determine the center frequency point f1 plus bandwidth 2W1 corresponding to this BWP, thereby determining that the frequency range is f1-W1 to f1+W1.

[0056] For example, cell information such as a cell identifier (number) can be reported, and the network device determines the corresponding cell based on the cell identifier, and then determines the center frequency point f2 and bandwidth 2W2 set for this cell, thereby determining that the frequency range is f2-W2 to f2+W2.

[0057] In one embodiment, cell group information such as MCG (Master Cell Group) or SCG (Secondary Cell Group) can be reported, and the network device can determine the center frequency point f3 and bandwidth 2W3 set for the corresponding cell group based on the cell group information, thereby determining that the frequency range is f3-W3 to f3+W3.

[0058] In one embodiment, measurement object information such as the identifier (number) of the measurement object can be reported, and the network device can determine the center frequency point f4 and bandwidth 2W4 set for the corresponding measurement object based on the measurement object information, thereby determining that the frequency range is f4-W4 to f4+W4.

[0059] In one embodiment, when the type includes at least one of bandwidth portion information, cell information, cell group information, and measurement object information, the frequency range information further includes start frequency information and / or end frequency information of the frequency range.

[0060] If the terminal reports to the network device that the type of frequency range information is at least one of bandwidth portion information, cell information, cell group information, and measurement object information, the frequency range is determined relatively fixedly based on these types of information, for example, in the above embodiment, the bandwidth range is determined based on the center frequency point and the bandwidth.

[0061] In this embodiment, the frequency range information may further include start frequency information and / or end frequency information of the frequency range so that after the network device determines the frequency range based on the center frequency point and the bandwidth, the network device can further determine a more accurate frequency range in the frequency range based on the start frequency information and / or end frequency information.

[0062] For example, taking the type of frequency range information reported by the terminal to the network device as cell information, the network device can determine the corresponding cell based on the cell identifier, and further determine the center frequency point f2 and bandwidth 2W2 set for this cell, thereby determining that the frequency range is f2-W2 to f2+W2. The frequency range information further includes a start frequency f5 and an end frequency f6 of the frequency range, where f5 and f6 belong to the frequency range, thereby further determining that the frequency range is f5 to f6 from f2-W2 to f2+W2.

[0063] In one embodiment, the start frequency information includes a start frequency point number or a start physical resource block number, and / or the end frequency information includes an end frequency point number or an end physical resource block number.

[0064] The start frequency information and end frequency information can be characterized by a frequency point number, or can be characterized by a physical resource block (PRB) number.

[0065] For example, it may be characterized by a frequency point number, for example, the start frequency point number may be ARFCN-1, and the end frequency point number may be ARFCN-2, where the start frequency point is the frequency point corresponding to ARFCN-1 and the end frequency point is the frequency point corresponding to ARFCN-2; For example, they may be characterized by a physical resource block number, and the start frequency point number may be PRB-1, the end frequency point number may be PRB-2, and the start frequency point is a frequency point corresponding to PRB-1 (e.g., PRB-1 start frequency position or end frequency position), and the end frequency point is a frequency point corresponding to PRB-2 (e.g., PRB-2 start frequency position or end frequency position).

[0066] One PRB corresponds to 12 subcarriers, and the bandwidth of each subcarrier can be determined based on the subcarrier spacing (SCS). In this case, the bandwidth corresponding to one PRB is the bandwidth of 12 subcarriers.

[0067] In one embodiment, the information on the frequency range further includes subcarrier spacing (SCS) information corresponding to the frequency range, for example, the size of the SCS, for example, 15 kHz, 30 kHz, 60 kHz, 120 kHz, etc., and the parameter set identifier can instruct the network device to determine the bandwidth corresponding to the PRB based on the size of the SCS.

[0068] In one embodiment, the bandwidth information includes at least one of a bandwidth and a number of physical resource blocks.

[0069] The bandwidth information can be directly indicated by a bandwidth such as 10M, 20M, etc., or can be expressed by the number of PRBs, for example, by determining the bandwidth corresponding to each PRB, and further determining the bandwidth corresponding to this number of PRBs based on the number of PRBs.

[0070] In one embodiment, if the bandwidth information comprises a number n of physical resource blocks, when n is equal to 1, the frequency range information is used to indicate a frequency range starting from the center frequency point and having a length corresponding to a bandwidth of the physical resource block, or is used to indicate a frequency range ending from the center frequency point and having a length corresponding to a bandwidth of the physical resource block; if n is an even number, the frequency range information is used to indicate a frequency range whose midpoint is the center frequency point and whose length is a bandwidth corresponding to n physical resource blocks; If n is an odd number greater than 1, the frequency range information is used to indicate a frequency range whose midpoint is the center frequency point and whose length is a bandwidth corresponding to n physical resource blocks, or is used to indicate a frequency range whose start point is the center frequency point minus a bandwidth corresponding to n / 2 rounded number of physical resource blocks.

[0071] In one embodiment, when the number n of PRBs is a different value, the indicated frequency range may be different, and the manner in which the network device determines the frequency range based on the information reported by the terminal may also be different.

[0072] For example, if the number n of PRBs is 1, the start frequency position (or the end frequency position) of this PRB can be set as the center frequency point. For example, the start frequency position is 2.5 GHz, the SCS corresponding to the PRB is 15 kHz, and the bandwidth determined based on the SCS is 100 M.

[0073] Starting from 2.5GHz, 100M is the designated frequency range, i.e., the frequency range is 2.5GHz to 2.5GHz+100M; or ending at 2.5GHz, 100M is the designated frequency range, i.e., the frequency range is 2.5GHz-100M to 2.5GHz.

[0074] For example, if the number of PRBs n is an even number, the center frequency positions of the n PRBs can be used as the center frequency points. For example, if n=4, the center frequency of the four PRBs is 2.5 GHz, the SCS corresponding to the PRBs is 15 kHz, and the bandwidth determined based on the SCS is 100 M. The frequency range can be determined as 2.5 GHz-200 M to 2.5 GHz+200 M.

[0075] For example, if the number of PRBs, n, is an odd number greater than 1, the center frequency position of the n PRBs can be the center frequency point. For example, if n=3, the center frequency of the three PRBs is 2.5 GHz, the SCS corresponding to the PRBs is 15 kHz, and the bandwidth determined based on the SCS is 100 M. The frequency range can be determined as 2.5 GHz-150 M to 2.5 GHz+150 M.

[0076] If the bandwidth corresponding to the PRB is 100M, the 300M bandwidth of the three PRBs can be divided by 2, but in some cases it may not be divisible. For example, if the bandwidth corresponding to the PRB is 55M, 165 / 2M is not an integer, which will cause some problems in processing.

[0077] Therefore, n / 2 can be rounded, including, but not limited to, rounding up and rounding down. For example, if n=3, 3 / 2 can be rounded up to 2 and rounded down to 1. For example, rounding down can be performed when calculating the start frequency position of the frequency range and rounding up can be performed when calculating the end frequency position of the frequency range, and the determined frequency range can be 2.5 GHz -200 M to 2.5 GHz + 400 M. For example, rounding up can be performed when calculating the start frequency position of the frequency range and rounding down can be performed when calculating the end frequency position of the frequency range, and the determined frequency range can be 2.5 GHz -400 M to 2.5 GHz + 200 M.

[0078] Whether the rounding method is round-down or round-up may be instructed by the network device to the terminal, or may be agreed upon in advance between the network device and the terminal, or may be determined based on a protocol, thereby ensuring that the network device and the terminal have the same understanding of the rounding method, and further ensuring that the frequency range instructed by the terminal is the same as the frequency range determined by the network device.

[0079] 2 is a schematic flowchart of another interference information reporting method according to an embodiment of the present disclosure. As shown in FIG. 2, the method further includes the following step S201:

[0080] In step S201, an allowed frequency range corresponding to interference information that is allowed to be reported based on an instruction from a network device is determined.

[0081] The step of transmitting interference information to the network device includes the following step S202.

[0082] In step S202, determine that the frequency range related to the frequency interference problem belongs to the permitted frequency range, and send interference information to a network device.

[0083] In one embodiment, since terminals communicate based on different radio access technologies and cover a large frequency range, there are also many center frequency points corresponding to ARFCNs. Since the network device does not know at which center frequency point the terminal may experience a frequency interference problem, when the network device configures resources for reporting ARFCNs for the terminal, it needs to configure a large number of resources for the terminal to report various ARFCNs so that the terminal reports an ARFCN corresponding to any center frequency point within the frequency range available for communication. This results in a relatively large occupation of uplink communication resources.

[0084] According to this embodiment, the network device can limit the frequency range corresponding to the interference information reported by the terminal, for example, by instructing the terminal to only report interference information within a permitted frequency range, that is, the terminal can report interference information only when a frequency interference problem occurs within the permitted frequency range, so that the terminal transmits interference information to the network device only when the frequency range related to the frequency interference problem belongs to the permitted frequency range, and transmits interference information to the network device only when the frequency range related to the frequency interference problem does not belong to the permitted frequency range.

[0085] As a result, the center frequency point corresponding to the ARFCN reported by the terminal also belongs to the allowed frequency range, and therefore the network device does not need to configure resources for the terminal to report the ARFCN based on all frequency bands available to the terminal, but only needs to configure a small amount of resources for the terminal based on the allowed frequency range so that the terminal reports the ARFCN, which is advantageous for saving communication resources.

[0086] 3 is a schematic flowchart of a frequency range determination method according to an embodiment of the present disclosure. The frequency range determination method according to this embodiment can be applied to a network device, which can communicate with a terminal, and the network device includes, but is not limited to, a base station in a communication system, such as a 4G base station, a 5G base station, or a 6G base station, and the terminal includes, but is not limited to, a communication device, such as a mobile phone, a tablet computer, a wearable device, a sensor, or an Internet of Things device.

[0087] As shown in FIG. 3, the frequency range determination method may include the following steps S301 to S302.

[0088] In step S301, interference information transmitted from a terminal is received, and the interference information includes information on a frequency range related to a frequency interference problem.

[0089] In step S302, a frequency range related to frequency interference problems in the terminal is determined based on the information of the frequency range.

[0090] In one embodiment, the frequency interference problem includes, but is not limited to, interference between a wireless receiver and a wireless transmitter in a terminal, for example, IDC interference.

[0091] In one embodiment, when a condition for the terminal to transmit interference information is met, the terminal transmits the interference information to the network device, thereby instructing the network device on information of a frequency range related to the frequency interference problem so that the network device can determine the frequency range related to the frequency interference problem.

[0092] Because the interference information reported by the terminal to the network device includes information on the frequency range related to the frequency interference problem, as opposed to the reported interference information including only the center frequency point, it becomes easier for the network device to accurately determine the frequency range in which the interference occurs, and further makes it easier for the network device to accurately resolve the frequency interference problem.

[0093] For example, for frequency band A, the start frequency is f1, the end frequency is f2, and the center frequency point is (f1+f2) / 2. If a frequency interference problem occurs within the frequency range of f3 to f4 in frequency band A, and the frequency of f1 <f3<f4<(f1+f2) / 2である。

[0094] If the terminal instructs the network device only about the center frequency point, the network device can only determine that the frequency interference problem occurs near (f1+f2) / 2. However, since the frequency interference problem actually occurs within the frequency range of f3 to f4, the network device cannot accurately determine the frequency range in frequency band A where the frequency interference problem occurs based on the interference information reported by the terminal.

[0095] A method for a network device to solve the frequency interference problem is to instruct a terminal to suspend communication using a frequency around (f1+f2) / 2, but since a frequency interference problem occurs in the frequency range of f3 to f4, even if the terminal suspends use of a frequency around (f1+f2) / 2, the terminal still communicates using a frequency within the frequency range of f3 to f4, and the frequency interference problem still exists. In this case, the network device will not be able to accurately solve the frequency interference problem for the terminal.

[0096] However, according to this embodiment, among the interference information reported by the terminal to the network device, the frequency range information related to the frequency interference problem may be f3 to f4, so that the network device can accurately determine that the frequency interference problem has occurred within the frequency range of f3 to f4 in frequency band A.

[0097] A method for the network device to solve the frequency interference problem may be to instruct the terminal to suspend communication using frequencies within the f3-f4 frequency range, and when a frequency interference problem occurs in the f3-f4 frequency range, the terminal suspends communication using frequencies within the f3-f4 frequency range, thereby avoiding the frequency interference problem. As can be seen from the above, the network device can accurately solve the frequency interference problem for the terminal.

[0098] The method by which the network device solves the frequency interference problem for the terminal is not limited to instructing the terminal to suspend communication within the frequency range where the frequency interference problem occurs, and other methods may be selected as needed, for example, the network device itself suspends transmitting downlink information to the terminal within this frequency range.

[0099] The manner in which the terminal transmits interference information to the network device can be set as needed, for example, by radio resource control (RRC) signaling, by physical layer information, or in a random access process, and is not limited by the present disclosure.

[0100] In one embodiment, the terminal The frequency interference problem has occurred, the frequency interference problem has ceased; and a new frequency interference problem has occurred. If at least one of the following conditions is satisfied, the interference information is transmitted.

[0101] In one embodiment, the frequency range information is The frequency range in which the interference occurs, and and a combination of frequency ranges in which interference occurs. The frequency range in which interference occurs includes at least one of a frequency range that causes interference and a frequency range that is subject to interference.

[0102] In one embodiment, the frequency interference problem occurring in the terminal may be interference between two frequency ranges, such as frequency range #1 causing interference to frequency range #2, and the terminal can report the frequency range in which the interference occurred to the network device, for example, by reporting at least one of the two frequency ranges, frequency range #1 and frequency range #2, and indicating which of the reported frequency ranges causes interference and which frequency range is interfered with. This allows the terminal to determine the frequency range in which interference occurred and which of the received frequency ranges causes interference and which frequency range is interfered with.

[0103] In addition, the frequency interference problem that has occurred may be interference occurring between at least one pair of frequency ranges, or may be interference occurring between multiple pairs of frequency ranges, and the terminal may report multiple pairs of frequency ranges and indicate the relationship between the reported frequency ranges.

[0104] For example, a terminal may simultaneously experience interference from frequency range #1 on frequency range #2 and interference from frequency range #3 on frequency range #4. The frequency ranges reported by the terminal where interference occurs may include frequency range #1, frequency range #2, frequency range #3, and frequency range #4, indicating that frequency range #1 and frequency range #3 are the frequency ranges causing interference, frequency range #2 and frequency range #4 are the frequency ranges affected by interference, frequency range #1 corresponds to frequency range #2, and frequency range #3 corresponds to frequency range #4. This allows the network device to determine that frequency range #1 causes interference on frequency range #2 and frequency range #3 causes interference on frequency range #4.

[0105] In one embodiment, a frequency interference problem occurring at a terminal may be caused by a common effect (including but not limited to cross-modulation) of two or more frequency ranges causing interference in another frequency range, and the terminal may report to the network device the combination of frequency ranges in which the interference occurred, for example, the combination of frequency ranges in which the interference occurred due to the common effect.

[0106] For example, if the common effect of frequency range #5 and frequency range #6 causes interference to frequency range #7, the terminal can report the frequency range combination consisting of frequency range #5 and frequency range #6 to the network device, and can also report frequency range #7 to the network device. This allows the network device to determine that the common effect of frequency range #5 and frequency range #6 causes interference to frequency range #7. The type of common effect, such as cross-modulation, can also be instructed to the network device. This allows the terminal to determine which frequency ranges cause interference and which frequency ranges are interfered with among the frequency ranges in which interference occurs and the received frequency ranges, and can determine the type of common effect of the combination of frequency ranges causing interference.

[0107] In one embodiment, the combination of frequency ranges comprises a plurality of frequency ranges and / or frequencies, i.e. the combination of frequency ranges comprises at least one frequency range.

[0108] For example, the combination of frequency ranges may include frequency range #1 and frequency #2, where frequency range #1 is a frequency range with a bandwidth of 20 MHz centered on a frequency corresponding to absolute radio frequency channel number ARFCN-1, and frequency #2 is a frequency corresponding to ARFCN-2; Alternatively, the combination of frequency ranges may include frequency range #1 and frequency range #2, where frequency range #1 is a frequency range with a center frequency point at the frequency corresponding to ARFCN-1 and a bandwidth of 20 MHz, and frequency range #2 is a frequency range with a center frequency point at the frequency corresponding to ARFCN-2 and a bandwidth of 20 MHz.

[0109] In one embodiment, the interference information further includes a radio access technology corresponding to a frequency range in which interference occurs in the interference problem.

[0110] In one embodiment, the radio access technology is: Third Generation Partnership Project (3GPP) radio access technology and Global Positioning System (GPS) and Beidou System (BDS) and Global Navigation Satellite System (GNSS) and Wireless Local Area Networks (WLANs) and Galileo Positioning System (Galileo) and Indian Regional Navigation Satellite System (IRNSS) and Bluetooth (BT) and at least one of.

[0111] The radio access technology corresponding to the frequency range where interference occurs, which is included in the interference information, includes the radio access technology of the frequency range causing interference and / or the radio access technology of the frequency range affected by interference, for example, the radio access technology of the frequency range causing interference is WLAN and the frequency range affected by interference is NR. This allows the network device to accurately determine the radio access technology corresponding to the frequency range where interference occurs, and avoids the difficulty of the network device in distinguishing the radio access technology corresponding to the frequency range when there is overlap between frequency ranges included in different radio access technologies by reporting only the frequency range. This is advantageous for ensuring that the network device accurately solves the frequency interference problem for the terminal based on the radio access technology corresponding to the frequency range.

[0112] In one embodiment, the type of frequency range information is: a center frequency point number and bandwidth information associated with said center frequency point number; A start frequency point number and an end frequency point number, Bandwidth fraction information; Cell information, Cell group information; and measurement object information.

[0113] In one embodiment, the type of frequency range information reported by the terminal to the network device can be selected as needed.

[0114] In one embodiment, a center frequency point number and bandwidth information associated with the center frequency point number may be reported, and the center frequency point number may be characterized by an absolute radio frequency channel number ARFCN. For example, the reported center frequency point number is ARFCN-1 and the corresponding bandwidth information is 20M, allowing the network device to determine that the frequency range is from the frequency corresponding to ARFCN-1 minus 10M to the frequency corresponding to ARFCN-1 plus 10M.

[0115] In one embodiment, a start frequency point number and an end frequency point number can be reported, and the start frequency point number and the end frequency point number can be characterized by an absolute radio frequency channel number ARFCN. For example, the reported start frequency point number is ARFCN-1 and the end frequency point number is ARFCN-2, and the network device can thereby determine that the frequency range is from the frequency corresponding to ARFCN-1 to the frequency corresponding to ARFCN-2.

[0116] In one embodiment, bandwidth part (BWP) information such as a BWP identifier (number) is reported, and the network device can determine the corresponding BWP based on the BWP information, and then determine the center frequency point f1 plus bandwidth 2W1 corresponding to this BWP, thereby determining that the frequency range is f1-W1 to f1+W1.

[0117] For example, cell information such as a cell identifier (number) can be reported, and the network device determines the corresponding cell based on the cell identifier, and then determines the center frequency point f2 and bandwidth 2W2 set for this cell, thereby determining that the frequency range is f2-W2 to f2+W2.

[0118] In one embodiment, cell group information such as MCG (Master Cell Group) or SCG (Secondary Cell Group) can be reported, and the network device can determine the center frequency point f3 and bandwidth 2W3 set for the corresponding cell group based on the cell group information, thereby determining that the frequency range is f3-W3 to f3+W3.

[0119] In one embodiment, measurement object information such as the identifier (number) of the measurement object can be reported, and the network device can determine the center frequency point f4 and bandwidth 2W4 set for the corresponding measurement object based on the measurement object information, thereby determining that the frequency range is f4-W4 to f4+W4.

[0120] In one embodiment, when the type includes at least one of bandwidth portion information, cell information, cell group information, and measurement object information, the frequency range information further includes start frequency information and / or end frequency information of the frequency range.

[0121] If the terminal reports to the network device that the type of frequency range information is at least one of bandwidth portion information, cell information, cell group information, and measurement object information, the frequency range is determined relatively fixedly based on these types of information, for example, in the above embodiment, the bandwidth range is determined based on the center frequency point and the bandwidth.

[0122] In this embodiment, the frequency range information may further include start frequency information and / or end frequency information of the frequency range so that after the network device determines the frequency range based on the center frequency point and the bandwidth, the network device can further determine a more accurate frequency range in the frequency range based on the start frequency information and / or end frequency information.

[0123] For example, taking the type of frequency range information reported by the terminal to the network device as cell information, the network device cell can determine the corresponding cell based on the identifier, and further determine the center frequency point f2 and bandwidth 2 W2 set for this cell, thereby determining that the frequency range is f2-W2 to f2+W2. The frequency range information further includes the start frequency f5 and end frequency f6 of the frequency range, where f5 and f6 belong to the frequency range, thereby further determining that the frequency range is f5 to f6 from f2-W2 to f2+W2.

[0124] In one embodiment, the frequency range information further includes subcarrier spacing information corresponding to the frequency range.

[0125] In one embodiment, the start frequency information includes a start frequency point number or a start physical resource block number, and / or the end frequency information includes an end frequency point number or an end physical resource block number.

[0126] The start frequency information and end frequency information can be characterized by a frequency point number, and can also be characterized by a physical resource block (PRB) number.

[0127] For example, it may be characterized by a frequency point number, for example, the start frequency point number may be ARFCN-1, and the end frequency point number may be ARFCN-2, where the start frequency point is the frequency point corresponding to ARFCN-1 and the end frequency point is the frequency point corresponding to ARFCN-2; For example, they may be characterized by a physical resource block number, and the start frequency point number may be PRB-1, the end frequency point number may be PRB-2, and the start frequency point is a frequency point corresponding to PRB-1 (e.g., PRB-1 start frequency position or end frequency position), and the end frequency point is a frequency point corresponding to PRB-2 (e.g., PRB-2 start frequency position or end frequency position).

[0128] One PRB corresponds to 12 subcarriers, and the bandwidth of each subcarrier can be determined based on the subcarrier spacing (SCS). In this case, the bandwidth corresponding to one PRB is the bandwidth of 12 subcarriers.

[0129] In one embodiment, the information on the frequency range further includes subcarrier spacing (SCS) information corresponding to the frequency range, for example, the size of the SCS, for example, 15 kHz, 30 kHz, 60 kHz, 120 kHz, etc., and the parameter set identifier can instruct the network device to determine the bandwidth corresponding to the PRB based on the size of the SCS.

[0130] In one embodiment, the bandwidth information includes at least one of a bandwidth and a number of physical resource blocks.

[0131] The bandwidth information can be directly indicated by a bandwidth such as 10M, 20M, etc., or can be expressed by the number of PRBs, for example, by determining the bandwidth corresponding to each PRB, and further determining the bandwidth corresponding to this number of PRBs based on the number of PRBs.

[0132] In one embodiment, if the bandwidth information comprises a number n of physical resource blocks, when n is equal to 1, the frequency range information is used to indicate a frequency range starting from the center frequency point and having a length corresponding to a bandwidth of the physical resource block, or is used to indicate a frequency range ending from the center frequency point and having a length corresponding to a bandwidth of the physical resource block; if n is an even number, the frequency range information is used to indicate a frequency range whose midpoint is the center frequency point and whose length is a bandwidth corresponding to n physical resource blocks; If n is an odd number greater than 1, the frequency range information is used to indicate a frequency range whose midpoint is the center frequency point and whose length is a bandwidth corresponding to n physical resource blocks, or is used to indicate a frequency range whose start point is the center frequency point minus a bandwidth corresponding to n / 2 rounded number of physical resource blocks.

[0133] In one embodiment, when the number n of PRBs is a different value, the indicated frequency range may be different, and the manner in which the network device determines the frequency range based on the information reported by the terminal may also be different.

[0134] For example, if the number n of PRBs is 1, the start frequency position (or the end frequency position) of this PRB can be set as the center frequency point. For example, the start frequency position is 2.5 GHz, the SCS corresponding to the PRB is 15 kHz, and the bandwidth determined based on the SCS is 100 M.

[0135] Starting from 2.5GHz, 100M is the designated frequency range, i.e., the frequency range is 2.5GHz to 2.5GHz+100M; or ending at 2.5GHz, 100M is the designated frequency range, i.e., the frequency range is 2.5GHz-100M to 2.5GHz.

[0136] For example, if the number of PRBs n is an even number, the center frequency positions of the n PRBs can be used as the center frequency points. For example, if n=4, the center frequency of the four PRBs is 2.5 GHz, the SCS corresponding to the PRBs is 15 kHz, and the bandwidth determined based on the SCS is 100 M. The frequency range can be determined as 2.5 GHz-200 M to 2.5 GHz+200 M.

[0137] For example, if the number of PRBs, n, is an odd number greater than 1, the center frequency position of the n PRBs can be the center frequency point. For example, if n=3, the center frequency of the three PRBs is 2.5 GHz, the SCS corresponding to the PRBs is 15 kHz, and the bandwidth determined based on the SCS is 100 M. The frequency range can be determined as 2.5 GHz-150 M to 2.5 GHz+150 M.

[0138] If the bandwidth corresponding to the PRB is 100M, the 300M bandwidth of the three PRBs can be divided by 2, but in some cases it may not be divisible. For example, if the bandwidth corresponding to the PRB is 55M, 165 / 2M is not an integer, which will cause some problems in processing.

[0139] Therefore, n / 2 can be rounded, including but not limited to rounding down and rounding up. For example, if n=3, 3 / 2 can be rounded up to 2 or rounded down to 1. For example, rounding down can be performed when calculating the start frequency position of the frequency range and rounding up can be performed when calculating the end frequency position of the frequency range, and the determined frequency range can be 2.5 GHz -200 M to 2.5 GHz + 400 M. For example, rounding up can be performed when calculating the start frequency position of the frequency range and rounding down can be performed when calculating the end frequency position of the frequency range, and the determined frequency range can be 2.5 GHz -400 M to 2.5 GHz + 200 M.

[0140] Whether the rounding method is round-down or round-up may be instructed by the network device to the terminal, or may be agreed upon in advance between the network device and the terminal, or may be determined based on a protocol, thereby ensuring that the network device and the terminal have the same understanding of the rounding method, and further ensuring that the frequency range instructed by the terminal is the same as the frequency range determined by the network device.

[0141] 4 is a schematic flowchart of another frequency range determining method according to an embodiment of the present disclosure. As shown in FIG. 4, the method further includes the following step S401:

[0142] In step S401, the terminal is instructed on the permitted frequency range corresponding to the interference information that is permitted to be reported.

[0143] In one embodiment, since terminals communicate based on different radio access technologies and cover a large frequency range, there are also many center frequency points corresponding to ARFCNs. Since the network device does not know at which center frequency point the terminal may experience a frequency interference problem, when the network device configures resources for reporting ARFCNs for the terminal, it needs to configure a large number of resources for the terminal to report various ARFCNs so that the terminal reports an ARFCN corresponding to any center frequency point within the frequency range available for communication. This results in a relatively large occupation of uplink communication resources.

[0144] According to this embodiment, the network device can limit the frequency range corresponding to the interference information reported by the terminal, for example, by instructing the terminal to only report interference information within a permitted frequency range, that is, the terminal can report interference information only when a frequency interference problem occurs within the permitted frequency range, so that the terminal transmits interference information to the network device only when the frequency range related to the frequency interference problem belongs to the permitted frequency range, and transmits interference information to the network device only when the frequency range related to the frequency interference problem does not belong to the permitted frequency range.

[0145] As a result, the center frequency point corresponding to the ARFCN reported by the terminal also belongs to the allowed frequency range, and therefore the network device does not need to configure resources for the terminal to report the ARFCN based on all frequency bands available to the terminal, but only needs to configure a small amount of resources for the terminal based on the allowed frequency range so that the terminal reports the ARFCN, which is advantageous for saving communication resources.

[0146] Corresponding to the above embodiments of the interference information reporting method and the frequency range determining method, the present disclosure further provides embodiments of an interference information reporting device and a frequency range determining device.
