[0002] With the rapid development of wireless communication technology, wireless frequency bands are becoming increasingly congested. To ensure normal communication quality, interference detection and avoidance technologies are essential when there is frequency band overlap between different systems (such as New Radio (NR) and Long Term Evolution (LTE) systems). However, existing interference detection and avoidance technologies are relatively limited and have low spectrum utilization, thus affecting transmission performance. Summary of the Invention

The network-side device utilizes the terminal device to obtain frequency band measurement information of potentially interfering frequency bands and determines the strength of the interference in real time. In this way, the network-side device can dynamically adjust the available frequency bands of the terminal device to achieve better transmission performance.

[0026] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0027] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no inherent meaning. Therefore, "module," "part," or "unit" may be used interchangeably.

[0028] With the rapid development of wireless communication technology, wireless frequency bands are becoming increasingly congested. To ensure normal communication quality, when frequency bands overlap between different systems (such as NR and LTE), interference detection and avoidance techniques for co-band interference between different systems are essential. For example, Figure 1 This diagram illustrates the shared frequency bands between NR and LTE in existing technologies. Currently, the NR 2.6GHz band shares a 40MHz band with LTE, such as... Figure 1 The shaded areas indicate the D1 and D2 frequency bands. When LTE is not fully frequency-shifted, NR may be subject to LTE service interference and / or reference signal interference, such as Cell Reference Signal (CRS) interference and Physical Downlink Shared Channel (PDSCH) interference.

[0029] Currently, interference detection and avoidance technologies typically employ the following three approaches:

[0030] Option 1: When there is frequency band overlap between NR and LTE, NR does not use the overlapping frequency band. For example, if NR shares 40MHz of the 100MHz band with LTE, then NR will only have 60MHz of usable frequency band. The disadvantage of this option is that when interference is relatively low, the spectrum utilization is low due to the reduction in available frequency band.

[0031] Option 2: When there is frequency band overlap between NR and LTE, NR does not avoid it and continues to use the overlapping frequency band. The disadvantage of this option is that when the overlapping frequency band is heavily interfered with, NR will use the interfered frequency band, resulting in very low actual spectrum utilization.

[0032] Option 3 involves enabling NR and LTE to interact (also known as spectrum sharing). When NR and LTE share a site, NR can decide whether to use the shared frequency band based on LTE load, thus avoiding interference from co-located LTE cells. The drawback of this option is that NR can only avoid interference from co-located LTE cells. When neighboring sites also have LTE, NR cannot obtain information about neighboring LTE cells and therefore cannot avoid interference from non-co-located LTE cells. Figure 2 A schematic diagram of interfering cells in the prior art is shown, such as... Figure 2 As shown, both cell 1 and cell 2 are covered by NR and LTE. Cell 1 cannot obtain LTE information from cell 2, and the LTE signal from cell 2 is actually an interference signal for cell 1.

[0033] In summary, existing interference detection and avoidance technologies are limited, unable to assess interference in real time, and suffer from low spectrum utilization, thus affecting transmission performance. To address these issues, this invention provides a mobile communication network (including but not limited to 5th Generation (5G) technology). The network architecture of this network may include terminal devices and network-side devices (also referred to as network devices or access network devices). The terminal devices connect wirelessly to the network-side devices and can be fixed or mobile. This invention provides a frequency band scheduling method, communication nodes, and a computer-readable storage medium that can operate on the aforementioned network architecture. This method can determine the strength of frequency band interference between different systems in real time, thereby dynamically adjusting the available frequency bands of the terminal devices to achieve better transmission performance.

[0034] Network-side equipment refers to the access equipment through which terminal devices wirelessly access the mobile communication system. It can be a base station, an evolved NodeB (eNodeB), an Integrated Access and Backhaul (IAB) node, a relay node (RN), a transmission reception point (TRP), an access point (AP), a next-generation NodeB (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system. It can also be a module or unit that performs some of the functions of a base station; for example, it can be a central unit (CU), a distributed unit (DU), or an IAB-Mobile-Termination (MT) or IAB-DU. The embodiments of this invention do not limit the specific technologies or equipment forms used in the network-side equipment.

[0035] Terminal equipment can also be referred to as a terminal, user equipment (UE), mobile station, mobile terminal, etc. Terminal equipment can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality terminal devices, augmented reality terminal devices, wireless terminals in industrial control, wireless terminals in autonomous driving, wireless terminals in remote surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, IAB-MT, etc. The embodiments of this invention do not limit the specific technologies or device forms used in the terminal equipment.

[0036] The solutions provided in the embodiments of this application are described below in conjunction with network-side equipment and terminal equipment. In the description of this invention, the terms "system" and "network" are often used interchangeably. Terms such as "first," "second," and "third" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order. The first system and the second system mentioned in the embodiments of this invention are different communication systems; for example, the first system is NR and the second system is LTE. The various embodiments of this invention described below can be performed individually or in combination with each other, and the embodiments of this invention do not impose specific limitations in this regard.

[0037] Figure 3 A flowchart illustrating a frequency band scheduling method according to an embodiment is shown, as follows: Figure 3As shown, the method provided in this embodiment is applicable to network-side devices (such as base stations), and the method includes the following steps.

[0038] S110. The network-side device acquires a reference frequency band and at least one detection frequency band, wherein the reference frequency band is a frequency band in which the first system does not interfere with the second system, and the detection frequency band is a frequency band in which the first system and the second system interfere with each other.

[0039] Specifically, the network-side device involved in this embodiment of the invention is the network-side device of the first system. The method for obtaining the reference frequency band and at least one detection frequency band in step S110 may include the following two steps:

[0040] Step a1: The network-side device divides the frequency band of the first system into interference-free frequency bands and interference-prone frequency bands.

[0041] Step a2: The network-side device uses the interference-free frequency band as the reference frequency band and divides the interference frequency band into at least one detection frequency band according to the granularity of the second system.

[0042] For example, Figure 4 A schematic diagram illustrating a frequency band allocation method according to an embodiment is shown. Figure 4 As shown, the frequency band of the first system is divided into an interference-free frequency band BW0, and the interference frequency band is divided into n detection frequency bands according to the granularity of the second system (i.e., detection frequency band BW1, detection frequency band BW2, ..., detection frequency band BWn). It should be noted that the number of detection frequency bands can be one or more.

[0043] Granularity refers to the minimum increment of system memory expansion. Higher granularity results in a smaller granularity level; conversely, lower granularity results in a larger granularity level. Dividing the interfering frequency band according to the granularity of the second system ensures consistency between the detection frequency band and the granularity of the second system.

[0044] S120. The network-side device sends frequency band configuration information to the terminal device. The frequency band configuration information includes the configuration information of the reference frequency band and the configuration information of all detection frequency bands.

[0045] In one embodiment, the configuration information is a Channel State Information-Reference Signal (CSI-RS) configuration.

[0046] S130. The network-side equipment receives frequency band measurement information sent by the terminal equipment according to the frequency band configuration information. The frequency band measurement information includes measurement information of the reference frequency band and measurement information of all detected frequency bands.

[0047] In one embodiment, the measurement information is Channel State Information (CSI) information.

[0048] For the reference frequency band, since the configuration of the reference frequency band is periodic, the method for receiving the frequency band measurement information sent by the terminal device according to the frequency band configuration information in step S130 may include step b1; for the detection frequency band, since the configuration of the detection frequency band is non-periodic, the method for receiving the frequency band measurement information sent by the terminal device according to the frequency band configuration information in step S130 may include steps b2 and b3:

[0049] Step b1: The network-side equipment periodically receives measurement information of the reference frequency band sent by the terminal equipment.

[0050] For reference frequency bands configured periodically, the network-side equipment does not require instructions; the terminal equipment will periodically measure the reference frequency band and send the measurement information to the network-side equipment. The network-side equipment only needs to periodically receive the reference frequency band measurement information sent by the terminal equipment.

[0051] Step b2: At the interference detection time, the network-side device sends a frequency band detection instruction to the terminal device.

[0052] Step b3: The network-side device receives measurement information for all detection frequency bands sent by the terminal device.

[0053] For non-periodic detection frequency bands, the network-side device first needs to determine whether the interference detection time has been reached. When the interference detection time is reached, the network-side device sends a frequency band detection instruction to the terminal device, so that the terminal device can measure all detection frequency bands according to the frequency band detection instruction, and send the measurement information of all detection frequency bands to the network-side device at the reporting time point.

[0054] S140. The network-side equipment determines the available frequency bands for the terminal equipment based on the frequency band measurement information.

[0055] Specifically, the method for determining the available frequency bands of the terminal device based on frequency band measurement information in step S140 may include the following two steps:

[0056] Step c1: The network-side device obtains j detection frequency bands that meet preset conditions from i detection frequency bands based on the frequency band measurement information, where i≥1, 0≤j≤i, and i and j are integers.

[0057] The network-side device determines whether the difference between the measurement information of the x-th detection frequency band and the measurement information of the reference frequency band is greater than a preset threshold. If it is greater than the preset threshold, it means that the x-th detection frequency band does not meet the preset condition. If it is not greater than the preset threshold, it means that the x-th detection frequency band meets the preset condition. x is an integer and increases from 1 to i in units of 1.

[0058] That is, the network-side device sets x=1, determines whether the difference between the measurement information of the x-th detection frequency band and the measurement information of the reference frequency band is greater than a preset threshold; if it is greater than the preset threshold, it means that the x-th detection frequency band does not meet the preset condition; if it is not greater than the preset threshold, it means that the x-th detection frequency band meets the preset condition; sets x=x+1, and returns to execute the step of determining whether the difference between the measurement information of the x-th detection frequency band and the measurement information of the reference frequency band is greater than the preset threshold, until x=i.

[0059] Step c2: The network-side device uses j detection frequency bands and reference frequency bands as available frequency bands for the terminal device.

[0060] Assume that the frequency bands of the first system are divided into a reference frequency band BW 0, a detection frequency band BW 1, a detection frequency band BW 2, and a detection frequency band BW 3. The measurement information value of the reference frequency band BW 0 is 10, the measurement information value of the detection frequency band BW 1 is 10, the measurement information value of the detection frequency band BW 2 is 5, the measurement information value of the detection frequency band BW 3 is 1, and the preset threshold value is 3. First, if the difference between the measurement information of the detection band BW1 and the measurement information of the reference band BW0 calculated by the network-side device is 0, which is less than the preset threshold of 3, then the detection band BW1 meets the preset condition and is usable. Second, if the difference between the measurement information of the detection band BW2 and the measurement information of the reference band BW0 calculated by the network-side device is 5, which is greater than the preset threshold of 3, then the detection band BW2 does not meet the preset condition and is unusable. Finally, if the difference between the measurement information of the detection band BW3 and the measurement information of the reference band BW0 calculated by the network-side device is 9, which is greater than the preset threshold of 3, then the detection band BW3 does not meet the preset condition and is unusable. Ultimately, the usable frequency bands for the terminal device are the reference band BW0 and the detection band BW1.

[0061] The network-side equipment sends relevant information about the available frequency bands to the terminal equipment so that the terminal equipment can use the available frequency bands for data transmission.

[0062] It is understandable that after the network-side device identifies the j detection frequency bands and the reference frequency band as available frequency bands for the terminal device, it can further determine whether the communication quality of the terminal device at the previous moment (i.e., the state before acquiring the available frequency band) is better than the communication quality at the current moment. If the communication quality of the terminal device at the previous moment is better than the communication quality at the current moment, then the reference frequency band is adopted as the available frequency band for the terminal device, or the frequency band used by the terminal device is reverted to the previous moment. If the communication quality of the terminal device at the previous moment is not better than the communication quality at the current moment, then the status quo is maintained. This achieves more robust transmission performance and avoids misjudgments by the network-side device caused by mismeasurements by the terminal device.

[0063] Specifically, the communication quality of terminal equipment can be obtained through at least one of the following methods: interference measurement (such as measuring CSI information), transmission speed measurement, and bandwidth utilization measurement.

[0064] This invention provides a frequency band scheduling method applied to a network-side device, comprising: acquiring a reference frequency band and at least one detection frequency band, wherein the reference frequency band is a frequency band in which a first system does not interfere with a second system, and the detection frequency band is a frequency band in which the first system interferes with the second system; sending frequency band configuration information to a terminal device, wherein the frequency band configuration information includes configuration information of the reference frequency band and configuration information of all detection frequency bands; receiving frequency band measurement information sent by the terminal device according to the frequency band configuration information, wherein the frequency band measurement information includes measurement information of the reference frequency band and measurement information of all detection frequency bands; and determining the available frequency bands of the terminal device based on the frequency band measurement information. The network-side device utilizes the frequency band measurement information of potentially interfering frequency bands acquired by the terminal device to determine the strength of interference in the frequency band in real time. In this way, the network-side device can dynamically adjust the available frequency bands of the terminal device to obtain better transmission performance.

[0065] Figure 5 A flowchart illustrating another frequency band scheduling method provided in one embodiment is shown, as follows: Figure 5 As shown, the method provided in this embodiment is applicable to terminal devices (such as UEs), and the method includes the following steps.

[0066] S210. The terminal device receives frequency band configuration information sent by the network-side device. The frequency band configuration information includes configuration information of the reference frequency band and configuration information of all detection frequency bands. The reference frequency band is the frequency band in which the first system does not interfere with the second system, and the detection frequency band is the frequency band in which the first system interferes with the second system.

[0067] In one embodiment, the frequency band configuration information is CSI-RS configuration.

[0068] S220. The terminal device obtains and sends frequency band measurement information to the network-side device according to the frequency band configuration information. The frequency band measurement information includes the measurement information of the reference frequency band and the measurement information of all detected frequency bands.

[0069] In one embodiment, the measurement information is Channel State Information (CSI) information.

[0070] For the reference frequency band, since the configuration of the reference frequency band is periodic, the method for acquiring and sending frequency band measurement information to the network-side device in step S220 may include step d1; for the detection frequency band, since the configuration of the detection frequency band is non-periodic, the method for acquiring and sending frequency band measurement information to the network-side device in step S220 may include steps d2 and d3.

[0071] Step d1: The terminal device periodically measures the reference frequency band and sends the measurement information of the reference frequency band to the network side device.

[0072] For a periodic reference frequency band configuration, the network-side device does not need to provide instructions; the terminal device will periodically measure the reference frequency band and send the measurement information to the network-side device.

[0073] Step d2: At the interference detection time, the terminal device receives the frequency band detection indication sent by the network side device.

[0074] Step d3: The terminal device measures all detected frequency bands according to the frequency band detection instructions and sends the measurement information of all detected frequency bands to the network side device.

[0075] For non-periodic detection frequency bands, the network-side device first needs to determine whether the interference detection time has been reached. When the interference detection time is reached, the network-side device sends a frequency band detection instruction to the terminal device, so that the terminal device can measure all detection frequency bands according to the frequency band detection instruction, and send the measurement information of all detection frequency bands to the network-side device at the reporting time point.

[0076] S230: The terminal device receives information about available frequency bands sent by the network-side device.

[0077] This allows terminal devices to use available frequency bands for data transmission.

[0078] This invention provides a frequency band scheduling method applied to a terminal device, comprising: receiving frequency band configuration information sent by a network-side device, wherein the frequency band configuration information includes configuration information of a reference frequency band and configuration information of all detected frequency bands, the reference frequency band being a frequency band in which a first system does not interfere with a second system, and the detected frequency bands being frequency bands in which the first system interferes with the second system; acquiring and sending frequency band measurement information to the network-side device based on the frequency band configuration information, wherein the frequency band measurement information includes measurement information of the reference frequency band and measurement information of all detected frequency bands; and receiving relevant information of available frequency bands sent by the network-side device. The network-side device utilizes the frequency band measurement information of potentially interfering frequency bands obtained by the terminal device to determine the strength of interference in real time. In this way, the network-side device can dynamically adjust the available frequency bands of the terminal device to obtain better transmission performance.

[0087] In one embodiment, the decision module 12 is specifically used to determine whether the difference between the measurement information of the x-th detection frequency band and the measurement information of the reference frequency band is greater than a preset threshold; if it is greater than the preset threshold, it means that the x-th detection frequency band does not meet the preset condition; if it is not greater than the preset threshold, it means that the x-th detection frequency band meets the preset condition, where x is an integer and increases from 1 to i in units of 1.
