Abstract
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 radio transceivers for 4G LTE, 5G NR, Wireless Fidelity (WIFI), Bluetooth, and Global Navigation Satellite System (GNSS) and other Radio Access Technologies (RATs).
[0003] The frequencies at which signals are received by a radio receiver and the frequencies at which signals are transmitted by a radio transmitter may overlap, e.g., the frequencies at which signals are received and the frequencies at which signals are transmitted are adjacent frequencies or harmonic frequency portions, and the radio receiver will experience interference from the transmitter.
[0004] In addition, 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 that is interfered with, 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 with which the UE reports 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: determining that a condition for transmitting interference information is met; and transmitting 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, a communication device is provided that includes a processor and a memory for storing a computer program, and when the computer program is executed by the processor, the above-mentioned interference information reporting method is realized.
[0012] According to a sixth aspect of an embodiment of the present disclosure, there is provided a communications 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.
[0013] According to a seventh aspect of an embodiment of the present disclosure, there is provided a computer-readable storage medium having a computer program stored thereon, the computer program realizing the steps of the above interference information reporting method when executed by a 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-mentioned frequency range determination method when executed by a processor.
[0015] According to this embodiment, when the conditions for transmitting interference information are 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.
[0016] Because the interference information reported by the terminal to the network device includes information on a frequency range related to the frequency interference problem, as opposed to the reported interference information including only a 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Based on the embodiments of the present disclosure, all other embodiments that a person skilled in the art can obtain without creative labor belong to the scope of protection of the present disclosure.

These terms are merely used to distinguish between the same types of information. For example, the first piece of information can be referred to as the second piece of information, and similarly, the second piece of information can be referred to as the first piece of information, without departing from the scope of the embodiments of the present disclosure. Depending on the context, the word "if" as used herein can be interpreted as "when" or "in the case of" or "in response to determining."

However, one of ordinary skill in the art will appreciate that the term "greater" also includes the meaning "greater than," the term "smaller" also includes the meaning "less than," and the term "higher" also includes the meaning "more than," and the term "lower" also includes the meaning "less than."
[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 the present embodiment can be applied to a terminal, which includes but is not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, an Internet of Things device, etc. The terminal can communicate with a network device (e.g., a user equipment), which includes but is not limited to a base station, a core network, etc. in a communication system such as 4G, 5G, 6G, etc.
[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 of a frequency range related to a frequency interference problem.
[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 a frequency range related to the frequency interference problem, as opposed to the reported interference information including only a 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. A frequency interference problem occurs within the frequency range from f3 to f4 in frequency band A, and 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 a frequency interference problem occurs near (f1+f2) / 2. However, since the frequency interference problem actually occurs within the frequency range from 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 the network device to solve the frequency interference problem may be to instruct the 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 the frequency around (f1+f2) / 2, the terminal still communicates using a frequency within the frequency range of f3 to f4, so the frequency interference problem still exists. In this case, the network device cannot 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 a 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 a frequency within the f3-f4 frequency range, and the frequency interference problem can be avoided by suspending communication using a frequency within the f3-f4 frequency range when a frequency interference problem occurs within the f3-f4 frequency range. As can be seen from the above, the network device can accurately solve the frequency interference problem for the terminal.
[0034] The manner in 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 in which the frequency interference problem occurs, and other manners may be selected as necessary, for example, the network device itself suspends transmitting downlink information to the terminal in this frequency range.
[0035] In addition, the manner in which the terminal transmits interference information to the network device can be configured as necessary, and may be, for example, transmitted by Radio Resource Control (RRC) signaling, transmitted by physical layer information, or transmitted in a random access process, and is not limited by the present disclosure.
[0036] In one embodiment, the condition is: The occurrence of the frequency interference problem; The frequency interference problem has ceased; and and the emergence 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, so that the network device may determine that a frequency interference problem occurs 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 has 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 has occurred within the frequency range has stopped, and further release the restriction on the terminal for solving the frequency interference problem, e.g., instruct 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 determines that a frequency interference problem occurs for the terminal in a 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 comprises: 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 causing interference and a frequency range 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 may 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, among the reported frequency ranges, the frequency range causing interference and the frequency range that is interfered with.
[0042] In addition, the frequency interference problem that occurs 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 is simultaneously experiencing interference in frequency range #2 by frequency range #1 and interference in frequency range #4 by frequency range #3. The frequency ranges where interference occurs reported by the terminal may include frequency range #1, frequency range #2, frequency range #3, and frequency range #4, and may indicate that frequency range #1 and frequency range #3 are frequency ranges that cause interference, frequency range #2 and frequency range #4 are frequency ranges that are subject to 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 in frequency range #2 and frequency range #3 causes interference in frequency range #4.
[0044] In one embodiment, a frequency interference problem occurring at a terminal may be 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 occurs, e.g., the combination of frequency ranges in which the interference occurs 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 combination of frequency ranges 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 having a bandwidth of 20 MHz with a frequency corresponding to absolute radio frequency channel number ARFCN-1 as a center frequency point, and frequency #2 is a frequency corresponding to ARFCN-2; Or the combination of frequency ranges may include frequency range #1 and frequency range #2, where frequency range #1 is a frequency range having a center frequency point at a frequency corresponding to ARFCN-1 and a bandwidth of 20 MHz, and frequency range #2 is a frequency range having a center frequency point at a frequency corresponding to ARFCN-2 and a bandwidth of 20 MHz.
[0048] In one embodiment, the interference information further includes the radio access technology of the interference problem corresponding to the frequency range in which the interference occurs.
[0049] In one embodiment, the radio access technology is: 3rd Generation Partnership Project (3GPP) radio access technologies, such as LTE (Long Term Evolution), NR (New Radio), Global Positioning System (GPS) and The Beidou System (BDS) and Global Navigation Satellite System (GNSS) and Wireless Local Area Network (WLAN) and Galileo Positioning System (Galileo) Indian Regional Navigation Satellite System (IRNSS) 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 where interference occurs and / or the radio access technology of the frequency range where interference occurs, for example, the radio access technology of the frequency range where interference occurs is WLAN, and the frequency range where interference occurs 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 by reporting only the frequency range when there is overlap between the frequency ranges included in different radio access technologies. It is advantageous to ensure that the network device accurately solves the frequency interference problem 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 reported by the terminal to the network device can be selected as needed.
[0053] In one embodiment, a center frequency point number and bandwidth information associated with said 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, whereby the network device can 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 may be reported, and the start frequency point number and the end frequency point number may 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 further determine the center frequency point f1 sum 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 further 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 an identifier (number) of a 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] When 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 the 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 a corresponding cell based on a cell identifier, and further determine a center frequency point f2 and a bandwidth 2W2 set for the 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 in 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, and can also be characterized by a physical resource block (PRB) number.
[0065] For example, 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, it may be characterized by a physical resource block number, e.g., the start frequency point number may be PRB-1 and the end frequency point number may be PRB-2, where the start frequency point is a frequency point corresponding to PRB-1 (e.g., the PRB-1 start frequency position or end frequency position) and the end frequency point is a frequency point corresponding to PRB-2 (e.g., the 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 space (SCS), in which case the bandwidth corresponding to one PRB is the bandwidth of 12 subcarriers.
[0067] In one embodiment, the information of the frequency range further includes subcarrier spacing (SCS) information corresponding to the frequency range, for example, a 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 a 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 the bandwidth, such as 10M, 20M, etc., or can be expressed by the number of PRBs, for example, 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, when the bandwidth information comprises a number n of physical resource blocks, If 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 the bandwidth of the physical resource block, or is used to indicate a frequency range ending at the center frequency point and having a length corresponding to the bandwidth of the physical resource block; if n is an even number, the frequency range information is used to indicate a frequency range having a midpoint at the center frequency point and a length corresponding to a bandwidth of n physical resource blocks; If n is an odd number greater than 1, the frequency range information is used to indicate a frequency range having a midpoint at the center frequency point and a length corresponding to a bandwidth of n physical resource blocks, or is used to indicate a frequency range having a start point at the center frequency point minus a bandwidth corresponding to a round number of n / 2 physical resource blocks and a length corresponding to a bandwidth of n 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, when the number n of PRBs is 1, the start frequency position (or the end frequency position) of this PRB can be 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, the specified frequency range is 100M, i.e. the frequency range is 2.5GHz~2.5GHz+100M; or ending at 2.5GHz, the specified frequency range is 100M, i.e. the frequency range is 2.5GHz-100M~2.5GHz.
[0074] For example, when the number n of PRBs is an even number, the center frequency positions of the n PRBs can be the center frequency points, for example, n=4, the center frequency of the 4 PRBs is 2.5GHz, the SCS corresponding to the PRBs is 15kHz, and the bandwidth determined based on the SCS is 100M. It can be determined that the frequency range is 2.5GHz-200M~2.5GHz+200M.
[0075] For example, when the number n of PRBs is an odd number greater than 1, the center frequency positions of the n PRBs can be the center frequency points, for example, n=3, the center frequency of the three PRBs is 2.5GHz, the SCS corresponding to the PRBs is 15kHz, and the bandwidth determined based on the SCS is 100M. It can be determined that the frequency range is 2.5GHz-150M~2.5GHz+150M.
[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, and there are some problems to handle.
[0077] Therefore, n / 2 can be rounded, including but not limited to rounding up and rounding down. For example, when n=3, 3 / 2 can be rounded up to 2 and rounded down to 1. For example, rounding down is performed when calculating the start frequency position of the frequency range, and rounding up is performed when calculating the end frequency position of the frequency range, and the determined frequency range may be 2.5GHz-200M to 2.5GHz+400M. For example, rounding up is performed when calculating the start frequency position of the frequency range, and rounding down is performed when calculating the end frequency position of the frequency range, and the determined frequency range may be 2.5GHz-400M to 2.5GHz+200M.
[0078] In addition, 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 permitted to be reported is determined based on an instruction from a network device.
[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 the terminals communicate based on different radio access technologies and relate to 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 have a frequency interference problem, when the network device configures resources for reporting ARFCNs for the terminal, it needs to configure a large amount 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 allow the terminal to report only the interference information within the permitted frequency range, that is, the terminal can report the interference information only when the frequency interference problem occurs within the permitted frequency range, so that the terminal transmits the 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 the 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 permitted 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 permitted 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 the 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, a 6G base station, etc., 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, an Internet of Things device, etc.
[0087] As shown in FIG. 3, the frequency range determining 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 of a frequency range related to a frequency interference problem.
[0089] In step S302, a frequency range related to a frequency interference problem 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 a 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. A frequency interference problem occurs within the frequency range from f3 to f4 in frequency band A, and 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 a frequency interference problem occurs near (f1+f2) / 2. However, since the frequency interference problem actually occurs within the frequency range from 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 the network device to solve the frequency interference problem may be to instruct the 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 the frequency around (f1+f2) / 2, the terminal still communicates using a frequency within the frequency range of f3 to f4, so the frequency interference problem still exists. In this case, the network device cannot 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 a 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 a frequency within the f3-f4 frequency range, and the frequency interference problem can be avoided by suspending communication using a frequency within the f3-f4 frequency range when a frequency interference problem occurs within the f3-f4 frequency range. As can be seen from the above, the network device can accurately solve the frequency interference problem for the terminal.
[0098] The manner in 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 in which the frequency interference problem occurs, and other manners may be selected as necessary, for example, the network device itself suspends transmitting downlink information to the terminal in this frequency range.
[0099] In addition, the manner in which the terminal transmits interference information to the network device can be set as necessary, and may be, for example, transmitted by radio resource control (RRC) signaling, transmitted by physical layer information, or transmitted in a random access process, and is not limited by the present disclosure.
[0100] In one embodiment, the terminal The occurrence of the frequency interference problem; The frequency interference problem has ceased; and 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 comprises: 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 causing interference and a frequency range 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 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 receiving interference among the reported frequency ranges. This allows the terminal to determine the frequency range in which the interference occurs and which of the received frequency ranges is the frequency range causing interference and which is the frequency range receiving interference.
[0103] In addition, the frequency interference problem that occurs 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 experience simultaneous interference on frequency range #2 caused by frequency range #1 and interference on frequency range #4 caused by frequency range #3. The frequency ranges where interference occurs reported by the terminal may include frequency range #1, frequency range #2, frequency range #3, and frequency range #4, and may indicate that frequency range #1 and frequency range #3 are frequency ranges that cause interference, frequency range #2 and frequency range #4 are frequency ranges that are subject to 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 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 occurs, e.g., the combination of frequency ranges in which the interference occurs 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 indicated to the network device. This allows the terminal to determine which frequency range is the frequency range causing interference and which frequency range is the frequency range that is interfered with in the frequency range where interference occurs and in the frequency range where it is received, 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 having a bandwidth of 20 MHz with a frequency corresponding to absolute radio frequency channel number ARFCN-1 as a center frequency point, 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 having a center frequency point at a frequency corresponding to ARFCN-1 and a bandwidth of 20 MHz, and frequency range #2 is a frequency range having a center frequency point at a frequency corresponding to ARFCN-2 and a bandwidth of 20 MHz.
[0109] In one embodiment, the interference information further includes the radio access technologies in the interference problem that correspond to the frequency ranges in which interference occurs.
[0110] In one embodiment, the radio access technology is: 3rd 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) Indian Regional Navigation Satellite System (IRNSS) and Bluetooth (BT) and at least one of the following:
[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 by reporting only the frequency range when there is overlap between the frequency ranges included in different radio access technologies. It is advantageous to ensure 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 said 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, whereby the network device can 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 may be reported, and the start frequency point number and the end frequency point number may 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 further determine the center frequency point f1 sum 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 further 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 an identifier (number) of a 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] When 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 the 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 according to 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, and f5 and f6 belong to the frequency range, thereby further determining that the frequency range is f5 to f6 in 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, 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, it may be characterized by a physical resource block number, e.g., the start frequency point number may be PRB-1 and the end frequency point number may be PRB-2, where the start frequency point is a frequency point corresponding to PRB-1 (e.g., the PRB-1 start frequency position or end frequency position) and the end frequency point is a frequency point corresponding to PRB-2 (e.g., the 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 which case the bandwidth corresponding to one PRB is the bandwidth of 12 subcarriers.
[0129] In one embodiment, the information of the frequency range further includes subcarrier spacing (SCS) information corresponding to the frequency range, for example, a 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 a 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 the bandwidth, such as 10M, 20M, etc., or can be expressed by the number of PRBs, for example, 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, when the bandwidth information comprises a number n of physical resource blocks, If 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 the bandwidth of the physical resource block, or is used to indicate a frequency range ending at the center frequency point and having a length corresponding to the bandwidth of the physical resource block; if n is an even number, the frequency range information is used to indicate a frequency range having a midpoint at the center frequency point and a length corresponding to a bandwidth of n physical resource blocks; If n is an odd number greater than 1, the frequency range information is used to indicate a frequency range having a midpoint at the center frequency point and a length corresponding to a bandwidth of n physical resource blocks, or is used to indicate a frequency range having a start point at the center frequency point minus a bandwidth corresponding to a round number of n / 2 physical resource blocks and a length corresponding to a bandwidth of n 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, when the number n of PRBs is 1, the start frequency position (or the end frequency position) of this PRB can be 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, the specified frequency range is 100M, i.e. the frequency range is 2.5GHz~2.5GHz+100M; or ending at 2.5GHz, the specified frequency range is 100M, i.e. the frequency range is 2.5GHz-100M~2.5GHz.
[0136] For example, when the number n of PRBs is an even number, the center frequency positions of the n PRBs can be the center frequency points, for example, n=4, the center frequency of the 4 PRBs is 2.5GHz, the SCS corresponding to the PRBs is 15kHz, and the bandwidth determined based on the SCS is 100M. It can be determined that the frequency range is 2.5GHz-200M~2.5GHz+200M.
[0137] For example, when the number n of PRBs is an odd number greater than 1, the center frequency positions of the n PRBs can be the center frequency points, for example, n=3, the center frequency of the three PRBs is 2.5GHz, the SCS corresponding to the PRBs is 15kHz, and the bandwidth determined based on the SCS is 100M. It can be determined that the frequency range is 2.5GHz-150M~2.5GHz+150M.
[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, and there are some problems to handle.
[0139] Therefore, n / 2 can be rounded, including but not limited to round down and round up. For example, when n=3, 3 / 2 can be rounded up to 2 and rounded down to 1. For example, rounding down is performed when calculating the start frequency position of the frequency range, and rounding up is performed when calculating the end frequency position of the frequency range, and the determined frequency range may be 2.5GHz-200M to 2.5GHz+400M. For example, rounding up is performed when calculating the start frequency position of the frequency range, and rounding down is performed when calculating the end frequency position of the frequency range, and the determined frequency range may be 2.5GHz-400M to 2.5GHz+200M.
[0140] In addition, 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, an allowed frequency range corresponding to interference information that is allowed to be reported is indicated to the terminal.
[0143] In one embodiment, since the terminals communicate based on different radio access technologies and relate to 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 have a frequency interference problem, when the network device configures resources for reporting ARFCNs for the terminal, it needs to configure a large amount 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 allow the terminal to report only the interference information within the permitted frequency range, that is, the terminal can report the interference information only when the frequency interference problem occurs within the permitted frequency range, so that the terminal transmits the 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 the 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 permitted 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 permitted frequency range so that the terminal reports the ARFCN, which is advantageous for saving communication resources.
