DETAILED DESCRIPTION

[0041] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] It should be noted that due to space limitations, this application specification does not list all optional implementation methods. After reading this application specification, those skilled in the art should be able to think that as long as the technical features do not contradict each other, any combination of technical features can constitute an optional implementation method. Each embodiment is described in detail below.

[0046] In the application scenarios of 5G, mid-range IoT use cases such as industrial wireless sensors, video surveillance and wearable devices have put forward special requirements for 5G terminals, such as reduced complexity and cost, reduced size, and lower energy consumption. Therefore, NR (New Radio) low-complexity and low-cost terminals are defined to meet the needs of these scenarios. The terminal can be a RedCap terminal.

[0047] To reduce terminal complexity and cost, the maximum bandwidth supported by RedCap UE (User Equipment) can be reduced, the number of UE RX (Receive) and TX (Transport) antennas can be reduced, the maximum modulation order can be reduced, and the UE can be allowed to have longer processing time.

[0048] Video surveillance is a major application scenario for RedCap terminals. A large number of surveillance cameras are often deployed in campus networks and transmitted back to the surveillance server through 5G RedCap terminals. This scenario has a relatively large capacity demand for the 5G network uplink. In order to increase the uplink capacity, the base station deployment density is generally increased, but too dense base stations will increase uplink neighboring cell interference, which in turn affects the terminal uplink data.

[0049] The present application provides a 5G-based bandwidth adjustment method, device, electronic device and storage medium, which aim to solve the above technical problems in the prior art.

[0050] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0051] Figure 1 1 is a flow chart of a 5G-based bandwidth adjustment method provided in accordance with an embodiment of the present application. The method is applied to a lightweight 5G terminal and can be performed by a 5G-based bandwidth adjustment device. Figure 1 As shown, the method comprises the following steps:

[0052] S101. Determine the co-frequency neighboring cell of the current cell according to the cell bandwidth of the current cell corresponding to the lightweight 5G terminal; wherein the current cell represents the network cell to which the lightweight 5G terminal is connected, the partial bandwidth accessed by the lightweight 5G terminal in the current cell is the preset frequency domain position of the cell bandwidth of the current cell, and the co-frequency neighboring cell represents the network cell that overlaps with the frequency domain position of the current cell within a preset range.

[0053] Exemplarily, a lightweight 5G terminal may be a RedCap terminal. Currently, the cell bandwidth of a 5G network cell is 100Mhz, and the 5G RedCap terminal only accesses a 20Mhz BWP. For example, the BWP accessed by the RedCap terminal is 0-20Mhz. The cell accessed by the RedCap terminal is determined as the current cell, that is, the current cell refers to the network cell to which the lightweight 5G terminal is accessed. The specific frequency domain position of the BWP accessed by the RedCap terminal in the 100Mhz of the entire network cell may be determined by the base station, that is, the base station may set the frequency domain position of the RedCap terminal in the cell bandwidth of the current cell as a preset frequency domain position, for example, the preset frequency domain position may be 0-20Mhz. The base station may inform the RedCap terminal of the preset frequency domain position through RRC (Radio Resource Control) signaling, that is, the RedCap terminal may determine its own preset frequency domain position.

[0054] The cell bandwidths of different network cells can be the same or different. If the cell bandwidths of different cells are the same, the different cells are co-frequency cells. For example, there are three network cells, namely cell A, cell B and cell C. Among them, the cell bandwidth of cell A is 0-100Mhz, the cell bandwidth of cell B is 0-100Mhz, and the cell bandwidth of cell C is 200-300Mhz, then cell A and cell B are co-frequency cells.

[0055] The lightweight 5G terminal determines the cell bandwidth of the current cell it is connected to, and determines the co-frequency neighboring cells of the current cell based on the cell bandwidth of the current cell. A neighboring cell refers to a network cell near the current cell, which can be a network cell within a preset range. A co-frequency neighboring cell refers to a network cell within a preset range that overlaps with the frequency domain position of the current cell. The current cell can have one or more co-frequency neighboring cells. For example, the current cell is cell A, and the co-frequency neighboring cells of cell A are cell B and cell E.

[0056] S102. If it is determined that there is uplink neighboring cell interference, determine the target neighboring cell causing the interference from the same-frequency neighboring cells; wherein, the uplink neighboring cell interference represents the interference caused by the neighboring cells of the current cell to the uplink data of the terminal when the lightweight 5G terminal is performing uplink data transmission.

[0057] Exemplarily, after determining the co-frequency neighboring cells of the current cell, the lightweight 5G terminal can detect whether there is uplink neighboring cell interference. Uplink neighboring cell interference refers to the interference caused by the neighboring cells of the current cell when the lightweight 5G terminal is performing uplink data transmission, which can specifically be interference to the uplink data of the lightweight 5G terminal. For example, the data collected by the surveillance camera is transmitted back to the monitoring server through the 5G Redcap terminal, and the surrounding base stations will increase the uplink neighboring cell interference and affect the uplink data of the terminal.

[0058] The conditions for determining whether there is uplink neighboring cell interference may be preset. For example, a speed threshold may be preset, and the actual uplink rate is compared with the preset speed threshold. If the actual uplink rate is less than the preset speed threshold, it is determined that there is uplink neighboring cell interference.

[0059] If it is determined that there is uplink neighboring cell interference, a network cell is determined from the co-frequency neighboring cells, and the determined network cell is the target neighboring cell causing the interference. For example, the co-frequency neighboring cell closest to the current cell can be determined as the target neighboring cell. If it is determined that there is no uplink neighboring cell interference, there is no need to adjust the bandwidth, and the lightweight 5G terminal can continue to judge whether there is uplink neighboring cell interference in real time or regularly until it is determined that there is uplink neighboring cell interference.

[0060] In this embodiment, if it is determined that there is uplink neighboring cell interference, the target neighboring cell causing the interference is determined from the same-frequency neighboring cells, including: obtaining measurement information when uplink data is transmitted; wherein the data is data transmitted uplink by a lightweight 5G terminal, and the measurement information represents the uplink data of the lightweight 5G terminal; if the measurement information meets the preset interference condition, it is determined that there is uplink neighboring cell interference, and the target neighboring cell causing the interference is determined from the same-frequency neighboring cells.

[0061] Specifically, the lightweight 5G terminal can obtain its own measurement information when uplinking data in real time or periodically. For example, a detection period T1 can be preset, and the value of T1 can be 1-1000ms. In this embodiment, the detection period can be set to 100ms. The detection period can be set in the lightweight 5G terminal, and the detection period can also be set in the base station of the current cell. The base station of the current cell sends RRC signaling to send the detection period to the lightweight 5G terminal, so that the lightweight 5G terminal can obtain measurement information according to the preset detection period. Data refers to the data transmitted uplink by the lightweight 5G terminal. For example, it can be video data collected by a surveillance camera. The process of uplink transmission is to upload video data to the server through the lightweight 5G terminal. The measurement information can represent the uplink data and other related information of the lightweight 5G terminal when uplinking data. For example, it can be the amount of data transmitted uplink in a period of time.

[0062] Preset interference conditions, which are used to determine whether there is uplink neighboring cell interference. Determine whether the measurement information meets the preset interference conditions. If so, it is determined that there is uplink neighboring cell interference; if not, it is determined that there is no uplink neighboring cell interference. For example, the preset interference condition can be a threshold range. If the measurement information is not within the preset threshold range, it is determined that there is uplink neighboring cell interference. If it is determined that there is uplink neighboring cell interference, it is necessary to determine the target neighboring cell causing the interference from the same-frequency neighboring cells.

[0063] The beneficial effect of such a setting is that by determining whether there is uplink neighboring cell interference, the network bandwidth can be adjusted in a targeted manner to achieve effective suppression of interference, thereby improving the efficiency and accuracy of data transmission.

[0064] In this embodiment, the measurement information includes an average delay of an uplink packet data convergence protocol cache; if the measurement information satisfies a preset interference condition, it is determined that there is uplink neighboring cell interference, including: if the average delay of the uplink packet data convergence protocol cache is greater than a preset delay threshold, it is determined that there is uplink neighboring cell interference.

[0065] Specifically, the measurement information may include the average uplink PDCP (Packet Data Convergence Protocol) cache delay, and the lightweight 5G terminal can obtain the average uplink PDCP cache delay in real time or periodically.

[0066] A delay threshold is set in advance, and the average delay of the uplink PDCP cache is compared with the preset delay threshold. If the average delay of the uplink PDCP cache is greater than the preset delay threshold, it is determined that there is uplink neighboring cell interference; if the average delay of the uplink PDCP cache is less than or equal to the preset delay threshold, it is determined that there is no uplink neighboring cell interference. For example, the value range of the delay threshold can be 1-500ms. In this embodiment, the delay threshold is set to 50ms. The delay threshold can be set on a lightweight 5G terminal, or it can be set on the base station of the current cell, and then the base station sends RRC signaling to send the delay threshold to the lightweight 5G terminal.

[0067] The beneficial effect of such a setting is that the condition for judging the presence of interference may be that the average delay of the uplink PDCP buffer is greater than PDCP_TH, PDCP_TH is a preset delay threshold, and the judgment process is simple, which is conducive to improving the efficiency of interference suppression.

[0068] In this embodiment, the measurement information includes the reference signal received power of the current cell and the reference signal received power of the co-frequency neighboring cell; if the measurement information meets the preset interference condition, it is determined that there is uplink neighboring cell interference, including: determining a candidate neighboring cell from the co-frequency neighboring cell based on the reference signal received power of the co-frequency neighboring cell; determining the difference between the reference signal received power of the candidate neighboring cell and the reference signal received power of the current cell as the power difference; if the power difference is greater than the preset power threshold, it is determined that there is uplink neighboring cell interference.

[0069] Specifically, the measurement information may include the average uplink PDCP buffer delay, and may also include the RSRP (Reference Signal Receiving Power) of the current cell and the RSRP of the same-frequency neighboring cell. The RSRP of the current cell and the RSRP of the same-frequency neighboring cell may be obtained in real time or periodically, for example, according to a preset detection period T1.

[0070] After obtaining the RSRP of the co-frequency neighboring area, a co-frequency neighboring area can be selected from multiple co-frequency neighboring areas according to the RSRP of each co-frequency neighboring area as a candidate neighboring area. For example, the co-frequency neighboring area with the highest RSRP or the co-frequency neighboring area closest to the current cell can be determined as a candidate neighboring area. The RSRP of the candidate neighboring area is subtracted from the RSRP of the current cell to obtain the difference between the RSRP of the candidate neighboring area and the RSRP of the current cell as the power difference. A power threshold is set in advance, and the power difference is compared with the power threshold. If the power difference is greater than the preset power threshold, it is determined that there is uplink neighboring area interference; if the power difference is less than or equal to the preset power threshold, it is determined that there is no uplink neighboring area interference. For example, the value range of the power threshold can be -20 to 20db. In this embodiment, the power threshold is set to -10db. The power threshold can be set on a lightweight 5G terminal, or the base station of the current cell can set the power threshold, and then the base station sends RRC signaling to send the power threshold to the lightweight 5G terminal.

[0071] The beneficial effect of such a setting is that by comparing the RSRP difference, it is determined whether there is uplink neighboring cell interference, the judgment process is fast, and the efficiency of interference suppression is high. In addition, this embodiment can determine whether the average delay of the uplink PDCP cache is greater than the delay threshold, and whether the power difference is greater than the preset power threshold. If the average delay of the uplink PDCP cache is greater than the delay threshold, and the power difference is greater than the preset power threshold, it is considered that there is uplink neighboring cell interference. The accuracy of interference confirmation is higher, thereby improving the accuracy of interference suppression and avoiding bandwidth adjustment for cells that do not cause interference.

[0072] In this embodiment, a candidate neighboring cell is determined from the same-frequency neighboring cells according to the reference signal received power of the same-frequency neighboring cells, including: from the reference signal received power of the same-frequency neighboring cells, determining the same-frequency neighboring cell corresponding to the maximum value of the reference signal received power as the candidate neighboring cell.

[0073] Specifically, after detecting one or more co-frequency neighboring cells, a candidate neighboring cell can be determined from the co-frequency neighboring cells, and then the RSRP difference judgment can be performed. When determining the candidate neighboring cells, the RSRP of each co-frequency neighboring cell can be compared and sorted, and the co-frequency neighboring cell with the highest RSRP can be determined as the candidate neighboring cell.

[0074] After obtaining the candidate neighboring cells, it is only necessary to subtract the RSRP of the candidate neighboring cells from the RSRP of the current cell, without subtracting the RSRP of all co-frequency neighboring cells from the RSRP of the current cell.

[0075] The beneficial effect of such a setting is that by comparing the RSRP sizes of the same-frequency neighboring cells, the candidate neighboring cells most likely to cause interference are determined, the amount of subtraction calculations is reduced, the efficiency of judgment is improved, and the efficiency of interference suppression is further improved.

[0076] In this embodiment, determining the target neighboring cell causing interference from the same-frequency neighboring cells includes: determining, from the reference signal received power of the same-frequency neighboring cells, the same-frequency neighboring cell corresponding to the maximum value of the reference signal received power as the target neighboring cell.

[0077] Specifically, after determining that there is uplink neighboring cell interference, it is necessary to determine a target neighboring cell from the co-frequency neighboring cells, so as to adjust the bandwidth of the target neighboring cell. If the RSRP of the candidate frequency zone is used to determine whether there is uplink neighboring cell interference, the candidate neighboring cell can be directly determined as the target neighboring cell. If RSRP is not used to determine the interference, and only the uplink PDCP cache average delay is used for determination, it is also necessary to obtain the RSRP of each co-frequency neighboring cell, and determine the co-frequency neighboring cell with the highest RSRP as the target neighboring cell.

[0078] The beneficial effect of this setting is that the co-frequency neighboring cell with the highest RSRP is determined as the target neighboring cell, and targeted bandwidth adjustment is achieved for the co-frequency neighboring cell, avoiding bandwidth adjustment for multiple co-frequency neighboring cells, reducing the workload of bandwidth adjustment, and effectively improving the efficiency of interference suppression.

[0079] S103. Send the preset frequency domain position and the cell identifier of the target neighboring cell to the base station corresponding to the current cell; wherein the base station corresponding to the current cell is used to determine whether the lightweight 5G terminal has uplink neighboring cell interference, and if so, send the preset frequency domain position to the base station corresponding to the target neighboring cell; the base station corresponding to the target neighboring cell is used to adjust the position of part of the bandwidth used by the target neighboring cell according to the preset frequency domain position.

[0080] Exemplarily, after determining the target neighboring cell, the cell identifier of the target neighboring cell is obtained, and each network cell may correspond to a unique cell identifier. The lightweight 5G terminal sends its own preset frequency domain position and the cell identifier of the target neighboring cell to the current cell, specifically to the base station corresponding to the current cell, to notify the current cell of the presence of neighboring cell interference.

[0081] After receiving the message from the lightweight 5G terminal, the base station corresponding to the current cell further determines whether the lightweight 5G terminal really has uplink neighboring cell interference. If so, the preset frequency domain position is sent to the base station corresponding to the target neighboring cell. For example, the base station of the current cell can obtain the uplink average SINR (Signal to Interference plus Noise Ratio) of the lightweight 5G terminal in a preset time period. If the uplink average SINR is less than the preset signal-to-noise ratio threshold, it is considered that the lightweight 5G terminal does have uplink neighboring cell interference, and the preset frequency domain position is sent to the base station corresponding to the target neighboring cell.

[0082] After receiving the preset frequency domain position sent by the base station of the current cell, the base station corresponding to the target neighboring cell adjusts the BWP position used by itself according to the preset frequency domain position. That is, the target neighboring cell can modify the BWP frequency position of the cell to avoid overlapping with the BWP frequency position of the lightweight 5G terminal. And the target neighboring cell can notify all lightweight 5G terminals connected to it of the update of the BWP position through RRC signaling, prompting these terminals to re-access. In order to avoid the interruption of lightweight 5G terminal services in the cell caused by the modification of the BWP frequency domain position by the target neighboring cell, the target neighboring cell can agree on the BWP update time with the terminal connected to it through RRC signaling, and the base station of the target neighboring cell and the terminal connected to it will synchronously update the BWP position at the agreed update time, thereby suppressing interference after the update.

[0083] The embodiment of the present application provides a 5G-based bandwidth adjustment method, which detects one or more co-frequency neighboring areas through a lightweight 5G terminal accessing the current cell. The frequency domain position of the BWP accessed by the lightweight 5G terminal in the entire cell can be determined by the base station of the current cell. The lightweight 5G terminal determines whether there is interference from the co-frequency neighboring areas around it. If so, a target neighboring area causing interference is determined from the co-frequency neighboring areas. The preset frequency domain position and the ID of the target neighboring area are reported to the current cell. The current cell further confirms whether there is interference. If so, the target neighboring area is notified to modify the BWP frequency position to avoid the overlap of the target neighboring area and the BWP frequency position of the lightweight 5G terminal. Flexible configuration of the BWP positions of different cells is achieved, co-frequency interference is reduced or avoided, and interference from neighboring areas is suppressed, thereby improving the efficiency and accuracy of terminal data transmission.

[0084] Figure 2The present invention is a flow chart of a 5G-based bandwidth adjustment method provided in accordance with an embodiment of the present application. The method is applied to a base station corresponding to the current cell and can be executed by a 5G-based bandwidth adjustment device. Figure 2 As shown, the method comprises the following steps:

[0085] S201. Receive the preset frequency domain position and the cell identifier of the target neighboring area sent by the lightweight 5G terminal; wherein, the current cell represents the network cell to which the lightweight 5G terminal is connected, and the part of the bandwidth accessed by the lightweight 5G terminal in the current cell is the preset frequency domain position of the cell bandwidth of the current cell; the lightweight 5G terminal is used to determine the co-frequency neighboring area of ​​the current cell according to the cell bandwidth of the current cell; wherein the co-frequency neighboring area represents the network cell that overlaps with the frequency domain position of the current cell within a preset range; if it is determined that there is uplink neighboring area interference, determine the target neighboring area causing the interference from the co-frequency neighboring area; wherein the uplink neighboring area interference represents the interference caused by the neighboring area of ​​the current cell to the uplink data of the terminal when the lightweight 5G terminal is performing uplink data transmission; send the preset frequency domain position and the cell identifier of the target neighboring area to the base station corresponding to the current cell.

[0086] Exemplarily, the current cell can receive in real time the cell identifier of the target neighboring cell sent by a lightweight 5G terminal. The lightweight 5G terminal is a terminal connected to the current cell, for example, a RedCap terminal. The current cell can store the preset frequency domain positions of each lightweight 5G terminal connected to it. Therefore, the lightweight 5G terminal can send the preset frequency domain position and the cell identifier of the target neighboring cell to the current cell, or it can only send the cell identifier of the target neighboring cell. After receiving the message from the lightweight 5G terminal, the current cell searches for the preset frequency domain position corresponding to the lightweight 5G terminal.

[0087] A lightweight 5G terminal can determine the co-frequency neighboring cell of the current cell based on the cell bandwidth of the current cell; wherein the current cell represents the network cell to which the lightweight 5G terminal is connected, and the portion of the bandwidth accessed by the lightweight 5G terminal in the current cell is the preset frequency domain position of the cell bandwidth of the current cell, and the co-frequency neighboring cell represents the network cell that overlaps with the frequency domain position of the current cell within a preset range. If it is determined that there is uplink neighboring cell interference, the target neighboring cell causing the interference is determined from the co-frequency neighboring cells; wherein the uplink neighboring cell interference represents the interference caused by the neighboring cells of the current cell to the uplink data of the terminal when the lightweight 5G terminal is performing uplink data transmission. The lightweight 5G terminal sends the preset frequency domain position and the cell identifier of the target neighboring cell to the base station corresponding to the current cell.

[0088] If it is determined that uplink neighboring cell interference exists, the target neighboring cell causing the interference is determined from the co-frequency neighboring cells, including: obtaining measurement information when uplink data is transmitted; wherein the data is data transmitted uplink by a lightweight 5G terminal, and the measurement information represents the uplink data of the lightweight 5G terminal; if the measurement information meets the preset interference condition, it is determined that uplink neighboring cell interference exists, and the target neighboring cell causing the interference is determined from the co-frequency neighboring cells.

[0089] The measurement information includes an average delay of an uplink packet data convergence protocol cache; if the measurement information meets a preset interference condition, it is determined that there is uplink neighboring cell interference, including: if the average delay of the uplink packet data convergence protocol cache is greater than a preset delay threshold, it is determined that there is uplink neighboring cell interference.

[0090] The measurement information includes the reference signal received power of the current cell and the reference signal received power of the co-frequency neighboring cell; if the measurement information meets the preset interference condition, it is determined that there is uplink neighboring cell interference, including: determining a candidate neighboring cell from the co-frequency neighboring cell based on the reference signal received power of the co-frequency neighboring cell; determining the difference between the reference signal received power of the candidate neighboring cell and the reference signal received power of the current cell as the power difference; if the power difference is greater than the preset power threshold, it is determined that there is uplink neighboring cell interference.

[0091] Determining a candidate neighboring cell from the same-frequency neighboring cells according to the reference signal received power of the same-frequency neighboring cells includes: determining, from the reference signal received power of the same-frequency neighboring cells, the same-frequency neighboring cell corresponding to the maximum value of the reference signal received power as the candidate neighboring cell.

[0092] Determining a target neighboring cell causing interference from the same-frequency neighboring cells includes: determining, from the reference signal received power of the same-frequency neighboring cells, a same-frequency neighboring cell corresponding to a maximum value of the reference signal received power as the target neighboring cell.

[0093] S202. If it is determined that the lightweight 5G terminal has uplink neighboring cell interference, the preset frequency domain position is sent to the base station corresponding to the target neighboring cell; wherein the base station corresponding to the target neighboring cell is used to adjust the position of part of the bandwidth used by the target neighboring cell according to the preset frequency domain position.

[0094] Exemplarily, the base station of the current cell determines whether the lightweight 5G terminal really has uplink neighboring cell interference. If so, the preset frequency domain position can be sent to the base station corresponding to the target neighboring cell; if not, it is determined that no bandwidth adjustment is required. For example, the base station of the current cell can obtain relevant data such as the uplink rate of the lightweight 5G terminal when transmitting uplink data. If the obtained data does not meet the preset base station judgment conditions, it is considered that uplink neighboring cell interference does exist.

[0095] After receiving the preset frequency domain position sent by the base station corresponding to the current cell, the base station corresponding to the target neighboring cell can modify its own BWP position according to the preset frequency domain position to avoid overlapping of the BWP frequency position of the lightweight 5G terminal with that of the current cell. At the same time, it notifies all its own 5G RedCap terminals through RRC signaling that the BWP position has been updated, requiring all its own 5G RedCap terminals to re-access.

[0096] In this embodiment, if it is determined that the lightweight 5G terminal has uplink neighboring cell interference, the preset frequency domain position is sent to the base station corresponding to the target neighboring cell, including: obtaining the uplink average signal-to-noise ratio of the lightweight 5G terminal within a preset time period; if the uplink average signal-to-noise ratio is less than the preset signal-to-noise ratio threshold, it is determined that the lightweight 5G terminal has uplink neighboring cell interference, and the preset frequency domain position is sent to the base station corresponding to the target neighboring cell.

[0097] Specifically, after receiving the cell identifier of the target neighboring cell reported by the 5G RedCap terminal, the base station corresponding to the current cell determines the time of receiving the cell identifier as the receiving time T2. The base station corresponding to the current cell counts the uplink average SINR of the 5G RedCap terminal, i.e., the lightweight 5G terminal, within the time range (T2-T1, T2). Among them, T1 is the preset detection period, and the lightweight 5G terminal obtains the measurement information during uplink transmission every T1.

[0098] The base station corresponding to the current cell is preset with a signal-to-noise ratio threshold, and the uplink average SINR is compared with the preset signal-to-noise ratio threshold. If the uplink average SINR is less than the signal-to-noise ratio threshold, it is considered that there is uplink neighboring cell interference; if the uplink average SINR is equal to or greater than the signal-to-noise ratio threshold, it is considered that there is no uplink neighboring cell interference. After determining that there is uplink neighboring cell interference, the current cell carries the BWP location information of the interfered lightweight 5G terminal and sends a message to the target neighboring cell to notify the target neighboring cell to modify the BWP location.

[0099] The beneficial effect of such a setting is that the current cell confirms whether there is interference, avoids modifying the BWP of cells that do not cause interference, improves the modification accuracy of the BWP, and effectively suppresses interference.

[0100] The embodiment of the present application provides a 5G-based bandwidth adjustment method, which detects one or more co-frequency neighboring areas through a lightweight 5G terminal accessing the current cell. The frequency domain position of the BWP accessed by the lightweight 5G terminal in the entire cell can be determined by the base station of the current cell. The lightweight 5G terminal determines whether there is interference from the co-frequency neighboring areas around it. If so, a target neighboring area causing interference is determined from the co-frequency neighboring areas. The preset frequency domain position and the ID of the target neighboring area are reported to the current cell. The current cell further confirms whether there is interference. If so, the target neighboring area is notified to modify the BWP frequency position to avoid the overlap of the target neighboring area and the BWP frequency position of the lightweight 5G terminal. Flexible configuration of the BWP positions of different cells is achieved, co-frequency interference is reduced or avoided, and interference from neighboring areas is suppressed, thereby improving the efficiency and accuracy of terminal data transmission.

[0101] Figure 3 The present invention is a flow chart of a 5G-based bandwidth adjustment method provided according to an embodiment of the present application. The method is applied to a base station corresponding to a target neighboring cell and can be executed by a 5G-based bandwidth adjustment device. Figure 3 The method comprises the following steps:

[0102] S301. Receive a preset frequency domain position sent by a base station corresponding to a current cell; wherein the current cell represents a network cell to which a lightweight 5G terminal is connected, and a portion of the bandwidth accessed by the lightweight 5G terminal in the current cell is a preset frequency domain position of the cell bandwidth of the current cell; the lightweight 5G terminal is used to determine the same-frequency neighboring area of ​​the current cell according to the cell bandwidth of the current cell; wherein the same-frequency neighboring area represents a network cell that overlaps with the frequency domain position of the current cell within a preset range; if it is determined that there is uplink neighboring area interference, determine the target neighboring area causing the interference from the same-frequency neighboring area; wherein the uplink neighboring area interference represents the interference caused by the neighboring area of ​​the current cell to the uplink data of the terminal when the lightweight 5G terminal is performing uplink data transmission; send the preset frequency domain position and the cell identifier of the target neighboring area to the base station corresponding to the current cell; the base station corresponding to the current cell is used to receive the preset frequency domain position and the cell identifier of the target neighboring area sent by the lightweight 5G terminal; if it is determined that there is uplink neighboring area interference for the lightweight 5G terminal, send the preset frequency domain position to the base station corresponding to the target neighboring area.

[0103] Exemplarily, the lightweight 5G terminal determines the co-frequency neighboring area of ​​the current cell according to the cell bandwidth of the current cell; wherein the current cell represents the network cell to which the lightweight 5G terminal is connected, and the part of the bandwidth accessed by the lightweight 5G terminal in the current cell is the preset frequency domain position of the cell bandwidth of the current cell, and the co-frequency neighboring area represents the network cell that overlaps with the frequency domain position of the current cell within a preset range. If it is determined that there is uplink neighboring area interference, the target neighboring area causing interference is determined from the co-frequency neighboring area; wherein the uplink neighboring area interference represents the interference caused by the neighboring area of ​​the current cell to the uplink data of the terminal when the lightweight 5G terminal is performing uplink data transmission. The preset frequency domain position and the cell identifier of the target neighboring area are sent to the base station corresponding to the current cell, and the base station corresponding to the current cell receives the preset frequency domain position and the cell identifier of the target neighboring area sent by the lightweight 5G terminal. If it is determined that there is uplink neighboring area interference in the lightweight 5G terminal, the preset frequency domain position is sent to the base station corresponding to the target neighboring area, and the base station corresponding to the target neighboring area receives the preset frequency domain position sent by the base station corresponding to the current cell.

[0104] S302: Adjust the position of a portion of the bandwidth used by the target neighboring cell according to a preset frequency domain position.

[0105] Exemplarily, the target neighboring cell confirms whether its own BWP position overlaps with the preset frequency domain position. If there is no overlap, it is considered that the target neighboring cell does not cause interference, and the target neighboring cell may not adjust its bandwidth; if it is determined that there is an overlap, the target neighboring cell modifies its own BWP position to a BWP that does not overlap with the preset frequency domain position. The overlap between the BWP position of the target neighboring cell and the preset frequency domain position may be a complete overlap or a partial overlap. For example, if the preset frequency domain position is 0-20Mhz, and the BWP position of the target neighboring cell is also 0-20Mhz, then it is determined that the overlap between the BWP position of the target neighboring cell and the preset frequency domain position is a complete overlap; if the preset frequency domain position is 0-20Mhz, and the BWP position of the target neighboring cell is 10-50Mhz, then it is determined that the overlap between the BWP position of the target neighboring cell and the preset frequency domain position is a partial overlap.

[0106] In this embodiment, the position of the partial bandwidth used by the target neighboring cell is adjusted according to the preset frequency domain position, including: if the position of the partial bandwidth used by the target neighboring cell overlaps with the preset frequency domain position, the position of the partial bandwidth used by the target neighboring cell is adjusted to the position of the partial bandwidth other than the preset frequency domain position.

[0107] Specifically, modifying the BWP position of the target neighboring area to a BWP that does not overlap with the preset frequency domain position means that the BWP position of the target neighboring area does not overlap with the preset frequency domain position at all. For example, the preset frequency domain position is 0-20Mhz, and the modified BWP position of the target neighboring area is 30-50Mhz. In this embodiment, the BWP position of the target neighboring area is a continuous frequency domain, that is, the modified BWP position of the target neighboring area is continuous and does not overlap with the preset frequency domain position.

[0108] The beneficial effect of this setting is that the BWP frequency position of the target neighboring cell is modified to avoid overlap with the preset frequency position of the lightweight 5G terminal of the current cell, thereby suppressing interference.

[0109] In order to avoid the interruption of 5G RedCap terminal services in the target neighboring cell due to the modification of the BWP frequency domain position, the actual effective time T3 of the BWP update can be agreed upon through RRC signaling, and the base station and terminal in the target neighboring cell will update the BWP position synchronously at time T3. That is, the interference suppression is completed after reaching time T3.

[0110] The embodiment of the present application provides a 5G-based bandwidth adjustment method, which detects one or more co-frequency neighboring areas through a lightweight 5G terminal accessing the current cell. The frequency domain position of the BWP accessed by the lightweight 5G terminal in the entire cell can be determined by the base station of the current cell. The lightweight 5G terminal determines whether there is interference from the co-frequency neighboring areas around it. If so, a target neighboring area causing interference is determined from the co-frequency neighboring areas. The preset frequency domain position and the ID of the target neighboring area are reported to the current cell. The current cell further confirms whether there is interference. If so, the target neighboring area is notified to modify the BWP frequency position to avoid the overlap of the target neighboring area and the BWP frequency position of the lightweight 5G terminal. Flexible configuration of the BWP positions of different cells is achieved, co-frequency interference is reduced or avoided, and interference from neighboring areas is suppressed, thereby improving the efficiency and accuracy of terminal data transmission.
