Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a frame header offset value configuration method, device, operation and maintenance center, and base station. Background Art

[0002] Due to limited spectrum resources, base stations in some cells may use the same frequency band for communication. This can cause co-channel interference between base stations in these cells, degrading communication quality. For example, co-channel interference can occur between base stations in 4G co-frequency cells, 5G co-frequency cells, and 4G and 5G dual-mode shared RRU (Radio Remote Unit) cells.

[0003] In related technologies, a staff member can manually configure a frame header offset value through the Operation and Maintenance Center (OMC) to the EPLD (Erasable Programmable Logic Device) on the baseband board of each base station in the same-frequency cell. The EPLD offsets the frame header position of the data frames sent by the base station based on the configured frame header offset value, thereby aligning the frame headers of the data frames sent by the base stations in each same-frequency cell and reducing the same-frequency interference between the base stations in the same-frequency cell.

[0004] However, this solution requires staff to know in advance the frame header positions of the data frames sent by the base stations of each co-frequency cell, and plan the frame header offset values configured for the base stations of each co-frequency cell based on the frame header positions. Therefore, the labor cost is high and the configuration efficiency is low. Summary of the Invention

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] To more clearly illustrate the frame header offset value configuration method provided in an embodiment of the present invention, the following exemplifies a possible application scenario of the frame header offset value configuration method provided in an embodiment of the present invention. It should be understood that the following example is only one possible application scenario of the frame header offset value configuration method provided in an embodiment of the present invention. In other possible embodiments, the frame header offset value configuration method provided in an embodiment of the present invention can also be applied to other possible application scenarios, and the following example does not impose any limitation on this.

[0046] With the evolution of 5G mobile communication systems and the planning and deployment of NR (New Radio) networks by mobile communication operators, NR base stations and LTE (Long Term Evolution) base stations will coexist and share in the same network for a certain period of time in the future. Furthermore, the B41 frequency band is a spectrum resource allocated to the NR network. Although there are plans to re-use the B41 frequency band in 4G network TDD (Time Division Duplex) cells, there are still a considerable number of 4G and 5G B41 frequency band dual-mode co-RRU networks in operation. Therefore, how to ensure frame header alignment between 4G co-frequency cells, 5G co-frequency cells, and 4G and 5G B41 dual-mode co-RRU cells to reduce co-frequency interference between base stations in co-frequency cells has become a technical problem that needs to be solved urgently.

[0047] In related technologies, manual configuration can be used to achieve frame header alignment between co-frequency cells to reduce co-frequency interference between base stations in the same-frequency cells. However, manual configuration requires staff to know the frame header positions of each co-frequency cell in advance and plan the frame header offset value for each co-frequency cell based on the frame header positions. This results in high labor costs and low configuration efficiency.

[0048] Based on this, the embodiment of the present invention provides a method for configuring a frame header offset value, which is applied to an operation and maintenance center. The method can be as follows: Figure 1 Shown, including:

[0049] S101 , obtaining a detection result, where the detection result is obtained by a base station detecting an interference degree of an uplink data frame of the base station.

[0050] S102: After determining that the interference level reaches a preset level threshold according to the detection result, determine a frame header offset value.

[0051] S103, sending a configuration instruction carrying a frame header offset value to the base station, so that the base station configures the offset value for offsetting the frame header position of the data frame to be sent according to the configuration instruction, and returns to execute S101 until it is determined according to the detection result that the interference level is reduced to below the preset level threshold.

[0052] This embodiment is selected. Since theoretically the degree of interference to the uplink data frame can reflect the degree of co-channel interference, the operation and maintenance center can adaptively determine the frame header offset value when the base station is subject to a high degree of co-channel interference, and instruct the base station to configure the local offset value for offsetting the frame header position of the data frame to be sent according to the determined frame header offset value, until the co-channel interference to the base station is reduced to below the threshold, thereby realizing automatic configuration of the offset value of the base station, effectively saving labor costs and improving configuration efficiency.

[0053] Moreover, in some application scenarios, the interference to the data frames sent by the base station may include other interference in addition to co-channel interference, such as interference caused by the atmospheric duct phenomenon. For application scenarios where interference caused by the atmospheric duct phenomenon exists, when planning the frame header offset value of each co-frequency cell, the staff in the related technology need to analyze the interference type and interference source caused by the atmospheric duct phenomenon in the interference to the uplink data frame, so as to accurately plan the frame header offset value of each co-frequency cell, further increasing labor costs and reducing configuration efficiency. The frame header offset value configuration method provided in the embodiment of the present invention can solve this technical problem.

[0054] In S101, the representation of the detection result may vary depending on the application scenario. For example, in one possible embodiment, the detection result may include interference statistical information indicating the degree of interference. In another possible embodiment, the detection result may include status identification information indicating whether the degree of interference reaches a preset threshold.

[0055] Furthermore, after detecting the degree of interference on the uplink data frames of the base station and obtaining a detection result, the base station may actively or passively send the detection result to the operation and maintenance center. For example, the base station may detect the degree of interference on the uplink data frames of the base station every 10 ms to obtain a detection result, and send the obtained detection result to the operation and maintenance center after each detection result is obtained. Alternatively, the base station may detect the degree of interference on the uplink data frames of the base station every 10 ms to obtain a detection result, and save the detection result after each detection result is obtained. The operation and maintenance center may send a request message to the base station every 1 second, and upon receiving the request message, the base station may send the most recently saved detection result to the operation and maintenance center.

[0056] The base station can detect the degree of interference to the uplink data frame of the base station by calculating the IOT (Interference Over Thermal, average interference rise) of each PRB (Physical Resource Block) of the uplink data frame sent by the base station. For example, the base station can calculate the IOT of each PRB of the uplink data frame sent by the base station, and count the proportion of high-interference PRBs in the PRBs of the uplink subframe whose IOT is higher than a preset IOT threshold. This proportion can be used to indicate the degree of interference.

[0057] In a possible embodiment, when the ratio is higher than a preset ratio threshold, it can be determined that the interference level has reached the preset level threshold; when the ratio is lower than the preset ratio threshold, it can be determined that the interference level has not reached the preset level threshold.

[0058] For example, assuming that an uplink data frame sent by a base station includes N PRBs, the IOT measurement instantaneous value of each PRB in the uplink data frame can be calculated based on the pilot position to obtain the IOT of the PRB. Furthermore, assuming that the number of high-interference PRBs with an IOT greater than a preset IOT threshold among the N PRBs is n, the ratio of high-interference PRBs in the PRBs of the uplink subframe can be calculated to be n / N.

[0059] It is understandable that if the interference level is high, the IOT of each PRB in the uplink data frame will be larger due to the high interference level, so the proportion of high-interference PRBs in the PRBs of the uplink data frame is higher. If the interference level is low, the IOT of each PRB in the uplink subframe will be smaller due to the low interference level, so the proportion of high-interference PRBs in the PRBs of the uplink data frame is lower. Therefore, the interference level of the uplink data frame sent by the base station can be determined based on this ratio.

[0060] Furthermore, it is understandable that the calculation of the IOT of each PRB in the uplink data frame by the base station requires the use of system resources of the base station, resulting in a reduction in the system resources available for the base station to perform normal services and a degradation in the performance of the base station. Therefore, in one possible embodiment, the base station may not calculate the IOT of the UpPTS (Uplink Pilot Time Slot) in the special subframe of the uplink data frame, but only calculate the IOT of the PRBs in the normal subframe of the uplink data frame, so as to reduce the impact of the IOT calculation on the performance of the base station.

[0061] In S102, the preset degree threshold can be set according to actual needs. For example, if the communication quality requirement is high, the preset degree threshold can be set lower; if the communication quality requirement is low, the preset degree threshold can be set higher.

[0062] The method for determining the frame header offset value may vary depending on the application scenario. It is understandable that in the frame header offset configuration method provided in the embodiment of the present invention, the frame header offset value is determined after the interference level reaches a preset level threshold. Therefore, except for the first determination of the frame header offset value, when the frame header offset value is determined at other times, it can be considered that the previously determined frame header offset value cannot achieve frame header alignment. The frame header offset value determined to reduce co-channel interference should be a frame header offset value that can achieve frame header alignment. Therefore, in one possible embodiment, to improve configuration efficiency, the newly determined frame header offset value is different from the previously determined frame header offset value.

[0063] In S103, a configuration instruction carrying a frame header offset value may be sent to the baseband board of the base station, so that the EPLD of the baseband board configures the offset value used locally to offset the frame header position of the data frame to be sent as the frame header offset value according to the configuration instruction.

[0064] It is understandable that if the interference level is reduced to below the preset level threshold, it can be considered that the interference level of the data frame sent by the base station is already low. At this time, it can be considered that frame header alignment has been achieved, so the frame header offset value does not need to be configured.

[0065] The following will explain how to determine the frame header offset value. Figure 2 ,include:

[0066] S201: Determine a frame header offset value according to a pre-configured adjustment range.

[0067] When the frame header offset value is first determined, the preset initial value is used as the frame header offset value. When the frame header offset value is determined for subsequent times, the frame header offset value is adjusted relative to the previously determined frame header offset value. The adjustment range can be pre-configured based on actual needs or user experience, and one or more adjustment ranges can be pre-configured. The preset initial value can be equal to the pre-configured adjustment range, or can be equal to another value other than the pre-configured adjustment range.

[0068] S202: Obtain interference statistical information.

[0069] The interference statistical information is used to indicate the degree of interference to the uplink data frame of the base station. For example, the interference statistical information may carry the number of high-interference PRBs. The more high-interference PRBs there are, the higher the degree of interference indicated by the interference statistical information; the fewer high-interference PRBs there are, the lower the degree of interference indicated by the interference statistical information.

[0070] S203 : Determine, based on the obtained interference statistical information, whether the change trend of the interference degree changes from a high-to-low trend to a low-to-high trend.

[0071] Theoretically, when the determined frame header offset value can achieve frame header alignment, the same-channel interference is minimized. Therefore, at this time, the interference degree of the uplink data frame sent by the base station reaches the minimum. For the convenience of description, it is assumed that the frame header offset value that can achieve frame header alignment is the target offset value, and the target offset value is recorded as P goal , then when the determined frame header offset value is less than P goal When the determined frame header offset value is greater than P, the interference level will decrease as the determined frame header offset value increases, that is, the interference level will change from high to low. goal The interference level will increase as the determined frame header offset value increases, that is, the interference level will show a trend from low to high. Therefore, when the determined frame header offset value gradually increases, if the trend of the interference level changes from high to low to low and then from low to high, it can be considered that the target offset value is between the currently determined frame header offset value and the previously determined frame header offset value.

[0072] S204: If the change trend of the interference level changes from a high-to-low trend to a low-to-high trend, reduce the adjustment range.

[0073] As analyzed above, if the interference level changes from a high-to-low trend to a low-to-high trend, the target offset value can be considered to be between the currently determined frame header offset value and the previously determined frame header offset value. Therefore, in order to make the determined frame header offset value as close as possible to (or even equal to) the target offset value, the adjustment range should be reduced.

[0074] In one possible embodiment, multiple adjustment ranges may be preconfigured, such as a first adjustment range and a second adjustment range, where the first adjustment range is greater than the second adjustment range and does not include the first adjustment range. The adjustment range is initially the first adjustment range and is reduced to the second adjustment range when the adjustment range is reduced. For example, the first adjustment range may be 100 μs, and the second adjustment range may be 25 μs.

[0075] It is understandable that if the pre-configured adjustment amplitude is large, it may result in a large gap between the determined frame header offset value and the target offset value. If the pre-configured adjustment amplitude is small, it will take more time to configure the offset value of the frame header position of the data frame to be transmitted by the base station to the target offset value, that is, the configuration efficiency is low. For example, assuming that the target offset value is 2050μs, if the pre-configured adjustment amplitude is 100μs, and the first determined frame header offset value is 100μs, then theoretically, the frame header offset values closest to the target offset value among the determined frame header offset values are 2100μs and 2000μs, which differ from the target offset value by 50μs. If the pre-configured adjustment amplitude is 50μs, and the first determined frame header offset value is 50μs, then theoretically, when the frame header offset value is determined for the 41st time, the determined frame header offset value is equal to the target offset value.

[0076] In this embodiment, assuming the target offset value is 2050 μs and the pre-configured adjustment amplitude is 100 μs, after the 21st determination of the frame header offset value, the interference level change trend changes from high to low to low to low to high. At this time, the adjustment amplitude is reduced. Assuming the adjustment amplitude is reduced to 25 μs, when the frame header offset value is determined for the 23rd time, the determined frame header offset value is equal to the target offset value. This embodiment can reduce the number of frame header offset value determinations required while ensuring the accuracy of the determined frame header offset value, thereby improving configuration efficiency.

[0077] When the base station offsets the position of the frame header of the data frame to be sent, it may advance the frame header position or lag the frame header position, that is, it may offset the frame header position in both the advance and lag directions. In one possible embodiment, the offset direction may be determined by the base station, and in another possible embodiment, the offset direction may also be indicated by the operation and maintenance center. Exemplarily, the configuration instruction may also include an offset flag for indicating the offset direction. After receiving the configuration instruction, the base station configures the offset value and offset direction for offsetting the frame header position of the data frame to be sent locally according to the configuration instruction. For example, the EPLD of the base station may configure the offset value for offsetting the frame header position of the data frame to be sent as the frame header offset value, and configure the offset direction for offsetting the frame header position of the data frame to be sent as the direction indicated by the offset flag according to the configuration instruction.

[0078] The offset flag can initially be used to indicate a first offset direction, which can be either an advance or a lag direction. The operation and maintenance center can modify the offset direction indicated by the offset flag, for example, Figure 3 Shown, including:

[0079] S301: Obtain interference statistical information for indicating the degree of interference.

[0080] For the interference statistical information, please refer to the related descriptions in S101 and S202 above, which will not be repeated here.

[0081] S302: Determine, based on the obtained interference statistical information, whether the change trend of the interference level is a change trend from high to low.

[0082] Taking the number of high-interference PRBs included in the interference statistical information as an example, if the number of high-interference PRBs carried by the interference statistical information decreases over time, it can be determined that the trend of the interference level is changing from high to low. If the number of high-interference PRBs carried by the interference statistical information does not decrease over time, it can be determined that the trend of the interference level is not changing from high to low. Here, decreasing over time means that the later the interference statistical information is received, the lower the number of high-interference PRBs carried. For example, assuming that one piece of interference statistical information is received at t=10μs and t=20μs, if the number of high-interference PRBs carried by the interference statistical information received at t=10μs is higher than the number of high-interference PRBs carried by the interference statistical information received at t=20μs, then the trend of the interference level is changing from high to low.

[0083] It is understandable that, assuming that the frame header position of the data frame sent by the base station needs to be advanced in order to achieve frame header alignment, if the frame header position of the data frame sent by the base station is delayed, the co-channel interference will theoretically be more severe, and therefore the degree of interference to the uplink data frame sent by the base station will increase. If the frame header position is advanced, the co-channel interference will theoretically be reduced, and therefore the degree of interference to the uplink data frame sent by the base station will be reduced. The same applies to the case where the frame header position needs to be delayed in order to achieve frame header alignment.

[0084] Therefore, if the interference level changes from high to low, it can be considered that the offset direction indicated by the offset flag is consistent with the offset direction that can achieve frame header alignment. If the interference level does not change from high to low, it can be considered that the offset direction indicated by the offset flag is opposite to the offset direction that can achieve frame header alignment.

[0085] S303: If the change trend of the interference level is not a change trend from high to low, then the offset direction indicated by the offset flag is changed to the opposite direction.

[0086] As analyzed above, if the interference level doesn't change from high to low, then the offset direction indicated by the offset flag is considered to be opposite to the offset direction that enables frame header alignment. Therefore, to achieve frame header alignment, the offset direction indicated by the offset flag needs to be changed to the opposite direction.

[0087] To more clearly illustrate the method for configuring the frame header offset value provided in the embodiment of the present invention, an exemplary description is given below:

[0088] In the first example, the base station can calculate the IOT of each PRB in the uplink data frame sent by the base station every 10ms, and count the number n of high-interference PRBs whose IOT is greater than a preset IOT threshold. Assuming that the base station uplink data frame contains N PRBs, the base station can calculate the ratio of high-interference PRBs in the PRBs of the uplink data frame, that is, n / N, and send interference statistics information carrying n to the operation and maintenance center. When the ratio is greater than the preset ratio threshold, the base station sets the preset status flag bit to logic 1. When the ratio is not greater than the preset ratio threshold, the base station sets the preset status flag bit to logic 0.

[0089] The OMC sends a request message to the base station every 1 second. After receiving the request message, the base station sends interference status information carrying a status flag to the OMC. A logical 1 indicates that the interference level has reached a preset threshold, while a logical 0 indicates that the interference level has not reached the preset threshold.

[0090] After receiving the interference status information, the operation and maintenance center determines whether the status flag carried is a logical 1. When it is determined that the status flag carried is a logical 1, the operation and maintenance center determines the frame header offset value every 1 second and sends the frame header offset value and offset flag to the baseband board of the base station. The offset value is (K*100+△*25)μs, where K represents the number of times the frame header offset value is determined with an adjustment amplitude of 100μs, and △ represents the number of times the frame header offset value is determined with an adjustment amplitude of 25μs. When the frame header offset value is determined for the first time, K=1 and △=0. The offset flag is an advance flag used to indicate an advance. After receiving the offset amplitude and offset flag, the baseband board configures the offset value used by the base station to offset the frame header position of the data frame to be transmitted as the frame header offset value, and configures the offset direction used to offset the frame header position of the data frame to be transmitted as the direction indicated by the offset flag.

[0091] After sending the frame header offset value and offset flag to the baseband board, the operation and maintenance center determines whether n carried in the received interference statistical information decreases over time. If n carried in the received interference statistical information decreases over time, the offset flag subsequently sent to the baseband board remains as an advance flag. If n carried in the received interference statistical information does not decrease over time, the offset flag subsequently sent to the baseband board is changed to a lag flag used to indicate lag.

[0092] And the operation and maintenance center determines whether the change trend of n carried in the received interference statistical information changes from a change trend from high to low to a change trend from low to high. If the change trend of n carried in the received interference statistical information does not change from a change trend from high to low to a change trend from low to high, then each time the frame header offset value is determined, the value of K is increased by one compared to the last time the frame header offset value was determined, and △ remains unchanged. For example, the frame header offset value determined by the operation and maintenance center for the first time is 100μs. If the change trend of n does not change from a change trend from high to low to a change trend from low to high after the frame header offset value is sent to the baseband board for the first time, then the frame header offset value determined for the second time is 200μs.

[0093] If the trend of n carried in the received interference statistics changes from a high-to-low trend to a low-to-high trend, then the value of △ for each subsequent determination of the frame header offset value is incremented by one compared to the previous determination of the frame header offset value, and K remains unchanged. For example, assuming the seventh frame header offset value determined by the operation and maintenance center is 700 μs, if the trend of n carried in the interference statistics changes from a high-to-low trend to a low-to-high trend after the seventh frame header offset value is sent to the baseband board, then the eighth determined frame header offset value is 725 μs.

[0094] When n carried in the received interference statistical information changes from a high-to-low trend to a low-to-high trend again, and the status identifier carried in the interference status information sent by the base station is a logic 0, it can be considered that frame header alignment has been achieved, and the operation and maintenance center terminates the frame header offset value configuration.

[0095] In the second example, the base station can calculate the IOT of each PRB in the uplink data frame sent by the base station every 10ms, and count the number n of high-interference PRBs whose IOT is higher than the preset IOT threshold, and send interference statistical information carrying n to the operation and maintenance center.

[0096] Every 1 second, the OMC calculates the ratio of high-interference PRBs to the PRBs in the base station's uplink data frame based on the number n of high-interference PRBs carried in the received interference statistics. Assuming that the base station's uplink data frame contains N PRBs, the OMC can calculate n / N and determine whether the ratio is greater than a preset ratio threshold.

[0097] When the operation and maintenance center determines that the ratio is greater than a preset ratio threshold, it determines a frame header offset value every 1 second and sends the frame header offset value and offset flag to the baseband board of the base station. The offset value is (K*100+△*25)μs, where K represents the number of times the frame header offset value is determined with an adjustment amplitude of 100μs, and △ represents the number of times the frame header offset value is determined with an adjustment amplitude of 25μs. When the frame header offset value is determined for the first time, K=1 and △=0, and the offset flag is an advance flag used to indicate an advance. After receiving the offset amplitude and offset flag, the baseband board configures the offset value used by the base station to offset the frame header position of the data frame to be transmitted as the frame header offset value, and configures the offset direction used to offset the frame header position of the data frame to be transmitted as the direction indicated by the offset flag.

[0098] After sending the frame header offset value and offset flag to the baseband board, the operation and maintenance center determines whether n carried in the received interference statistical information decreases over time. If n carried in the received interference statistical information decreases over time, the offset flag subsequently sent to the baseband board remains as an advance flag. If n carried in the received interference statistical information does not decrease over time, the offset flag subsequently sent to the baseband board is changed to a lag flag used to indicate lag.

[0099] And the operation and maintenance center determines whether the change trend of n carried in the received interference statistical information changes from a change trend from high to low to a change trend from low to high. If the change trend of n carried in the received interference statistical information does not change from a change trend from high to low to a change trend from low to high, then each time the frame header offset value is determined, the value of K is increased by one compared to the last time the frame header offset value was determined, and △ remains unchanged. For example, the frame header offset value determined by the operation and maintenance center for the first time is 100μs. If the change trend of n does not change from a change trend from high to low to a change trend from low to high after the frame header offset value is sent to the baseband board for the first time, then the frame header offset value determined for the second time is 200μs.

[0100] If the trend of n carried in the received interference statistics changes from a high-to-low trend to a low-to-high trend, then the value of △ for each subsequent determination of the frame header offset value is incremented by one compared to the previous determination of the frame header offset value, and K remains unchanged. For example, assuming the seventh frame header offset value determined by the operation and maintenance center is 700 μs, if the trend of n carried in the interference statistics changes from a high-to-low trend to a low-to-high trend after the seventh frame header offset value is sent to the baseband board, then the eighth determined frame header offset value is 725 μs.

[0101] When n carried in the received interference statistical information changes from a high-to-low trend to a low-to-high trend again, and the calculated ratio is less than the preset ratio threshold, it can be considered that frame header alignment has been achieved, and the operation and maintenance center terminates the frame header offset value configuration.
