Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a method, apparatus and base station for configuring an uplink carrier subject to interference. Background Technology

[0002] Hong Kong and Shenzhen are geographically adjacent, but their 2.6GHz spectrum planning strategies are inconsistent. Hong Kong plans for FDD standard, while Shenzhen plans for TDD standard. The two cannot be aligned in the time and frequency domains, resulting in varying degrees of uplink interference on the D3, D7, and D8 carriers of nearly 1,300 LTE cells.

[0003] With the commercialization of 5G networks, in order to simultaneously meet the requirements of 5G and 4G collaborative networking, the current only possible networking scheme in areas with interference is to use 60M (D4, D5, D6) for 5G NR and 40M (D1, D2) for 4G LTE. No services can be deployed on the 60M spectrum of high-interference cells, resulting in serious spectrum waste. At the same time, there will be difficulties such as insufficient 4G capacity and the inability to continuously deploy 5G at 100M. Summary of the Invention

[0016] Based on the support rate of mainstream user terminals for carrier aggregation in each frequency band and the current network capacity requirements, at least one non-interference carrier is configured as the primary carrier.

[0017] In one possible implementation, the dedicated secondary carrier is obtained by configuring the interfered carrier by the base station controller, and the uplink setting of the dedicated secondary carrier cell to prohibit user terminal access includes:

[0018] The base station controller will configure the interfered carrier as a dedicated secondary carrier and set the dedicated secondary carrier cell to not allow handover.

[0019] The base station of the dedicated secondary carrier cell sends an X2 message to the surrounding base stations to establish a connection, so that the user terminal can make uplink connections through the surrounding base stations.

[0020] In one possible implementation, the method for configuring the uplink interfered carrier further includes:

[0021] Set a timer to periodically activate the dedicated secondary carrier, so that the dedicated secondary carrier remains active.

[0022] Secondly, embodiments of this application also provide a configuration apparatus for an uplink carrier subject to interference, applied to a base station, comprising:

[0038] To better understand the technical solutions in this specification, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0039] It should be understood that the described embodiments are merely some, not all, of the embodiments in this specification. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without inventive effort are within the scope of protection of this specification.

[0040] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0041] Due to the geographical proximity of Hong Kong and Shenzhen and their differing 2.6GHz spectrum planning strategies, nearly 1300 LTE cells have experienced varying degrees of uplink interference on their D3, D7, and D8 carriers. With the commercialization of 5G networks, to simultaneously support 5G and 4G collaborative networking, the current network deployment scheme in the interference-affected areas can only use 60MHz (D4, D5, D6) for 5G NR and 40MHz (D1, D2) for 4G LTE. No services can be deployed on the 60MHz spectrum of the highly interference-prone cells, resulting in severe spectrum waste and a difficult situation where 4G capacity is insufficient and 5G cannot achieve continuous 100MHz network deployment.

[0042] Based on the above problems, this application provides a method, apparatus and base station for configuring uplink interfered carriers, which solves the problem of uplink interference on some carriers, improves the spectral efficiency of carrier aggregation, and realizes the rapid configuration of dedicated auxiliary carriers.

[0043] Figure 1 A flowchart illustrating a method for configuring an uplink carrier subject to interference, as provided in this application embodiment, is shown below. Figure 1 As shown, the above-mentioned configuration method for uplink interfered carriers may include:

[0044] S101: When a user terminal accesses the network via the primary carrier, a dedicated secondary carrier is intelligently allocated to the user terminal based on the predicted user spectrum efficiency. The primary carrier is obtained by the base station controller configuring at least one non-interference carrier, and the dedicated secondary carrier is obtained by the base station controller configuring an interference carrier. The uplink setting of the dedicated secondary carrier cell is set to prohibit user terminal access.

[0045] For example, the predicted user spectral efficiency can be obtained through an AI model or through other calculation methods. As long as the predicted user spectral efficiency can provide data for intelligent allocation of dedicated secondary carriers to user terminals, the purpose of this invention can be achieved. This embodiment does not limit the method for obtaining the predicted user spectral efficiency.

[0046] It is understandable that a normal carrier can host user terminals, but a dedicated secondary carrier cannot host users. It is used specifically in conjunction with the primary carrier PCC cell. Therefore, the secondary carrier is referred to as a dedicated secondary carrier.

[0047] In the above configuration method, the base station controller configures at least one non-interference carrier to obtain a primary carrier, and configures the interfered carrier to obtain a dedicated secondary carrier. The uplink of the dedicated secondary carrier cell is set to prohibit user terminal access. When the base station receives a user terminal accessing via the primary carrier, it intelligently allocates a dedicated secondary carrier to the user terminal based on the predicted user spectral efficiency. This method solves the problem of uplink interference on some carriers, improves the spectral efficiency of carrier aggregation, and enables rapid configuration of dedicated secondary carriers.

[0048] In the above configuration method, the primary carrier is obtained by the base station controller configuring at least one non-interference carrier, which may include: the base station controller statistically analyzing the terminal capabilities reported by user terminals to obtain the support rate of mainstream user terminals for carrier aggregation of each frequency band and the current network capacity requirements; and configuring at least one non-interference carrier as the primary carrier based on the support rate of mainstream user terminals for carrier aggregation of each frequency band and the current network capacity requirements.

[0049] In the above configuration method, the dedicated secondary carrier is obtained by the base station controller configuring the interfered carrier. Setting the uplink of the dedicated secondary carrier cell to prohibit user terminal access may include: the base station controller configuring the interfered carrier as a dedicated secondary carrier and setting the dedicated secondary carrier cell to not allow handover; the base station of the dedicated secondary carrier cell sends an X2 message to the surrounding base stations to establish a connection, so that the user terminal can make uplink connection through the surrounding base stations.

[0050] For example, since there are many spectrum resources in the existing network that can be used as the primary carrier PCC, such as the D band, F band, FDD1800, etc., when designing the carrier aggregation CA scheme, it is necessary to consider the carrier aggregation support capability of the existing commercial terminals, such as cross-system and cross-frequency band. Therefore, an evaluation of the 2.6G frequency band carrier aggregation capability of the mainstream user terminals in the existing network is required.

[0051] Figure 2 The diagram shown is a schematic representation of the carrier aggregation support rate of a mainstream user terminal according to an embodiment of this application. Figure 2 As can be seen, the carrier aggregation support rate of 2CC in the D band is the highest, reaching 72%. However, the support rates of 3CC in the D band and cross-band / cross-system carrier aggregation are not ideal. Therefore, this embodiment considers using carrier aggregation CA of 2CC in the D band as the research basis. The schematic diagram of the carrier aggregation support rate of mainstream user terminals is obtained by statistically analyzing the terminal capabilities reported by user terminals from the base station controller (i.e., the base station network management system), and evaluating the 2.6G band carrier aggregation capabilities of mainstream user terminals in the current network. This reflects the actual situation of carrier aggregation in the current network. Simultaneously, based on the carrier aggregation requirements in the current network, the current network capacity requirements are obtained, and a reasonable number of primary carriers are configured to meet the LTE capacity requirements.

[0052] In one feasible implementation, firstly, one non-interference carrier D2 or two non-interference carriers D1 & D2 are configured as the primary carrier PCC. The remaining non-interference carriers are used to carry 5G services, so that the interfering frequency band carries as many 4G services as possible, freeing up more frequency points for 5G services and improving 5G visibility. Then, the interfered 60MHz spectrum (D3, D7, D8) is configured with dedicated secondary carrier SCC to achieve downlink RB scheduling. Here, configuring the carrier as the primary carrier or dedicated secondary carrier is implemented in the base station network management backend, i.e., through the base station controller, and can be achieved through script configuration. Secondly, uplink access to the dedicated secondary carrier cell is prohibited for user terminals. For the 60MHz dedicated secondary carrier SCC, uplink physical layer HARK feedback is carried on the primary carrier, and uplink services are also carried on the primary carrier. Downlink uses TM3, and in this case, uplink sounding interference does not affect downlink performance.

[0053] Understandably, in the event of uplink interference, dedicated secondary carrier cells need to prohibit user access. This is achieved by setting the dedicated secondary carrier SCC cell to BAR state, preventing ordinary user terminals (UEs) from camping on that cell in idle state. Additionally, by sending X2 messages to surrounding sites, handover to this cell is not initiated. This ensures that no users camp on the dedicated secondary carrier, allowing it to be used only as a single downlink cell for carrier aggregation (CA) users.

[0054] For example, the steps of setting a dedicated secondary carrier cell to prohibit user terminal access may include: (1) setting the status of the dedicated secondary carrier cell to "Not allowed HO", (2) the source base station retrieves the neighbor cell list of the dedicated secondary carrier cell, (3) the source base station searches for the network element information corresponding to the neighbor cell according to the neighbor cell list, (4) retrieves X2 information according to the peer network element information, (5) sends "Target cell ID xxx not allowed HO" to the peer network element through the X2 link, (6) after receiving the information, the peer network element sets the "NoHoFlag" of the dedicated secondary carrier cell to 1 in the neighbor cell list of the peer network management system, and (7) replies to the source base station "Succeed". The completion of the above steps completes the setting of the dedicated secondary carrier cell to the mode of prohibiting user terminal access.

[0055] Figure 3 A flowchart illustrating another uplink interference carrier configuration method provided in this application embodiment is shown below. Figure 3 As shown, this application Figure 1 In the illustrated embodiment, step 101 may include:

[0056] Step 201: When the user terminal accesses via the main carrier, obtain the beam information of the user terminal;

[0057] Step 202: Index the corresponding grid in the preset virtual grid according to the beam information to obtain the predicted user spectral efficiency;

[0058] Step 203: Intelligently allocate dedicated secondary carriers to user terminals based on the predicted user spectrum efficiency.

[0059] In practical LTE networks operating in the 2.6GHz band, multi-carrier coordination is complex, and resource utilization efficiency is difficult to achieve at the level of a single carrier with high bandwidth. Assuming a carrier aggregation (CA) user terminal supporting 2CC, with the primary carrier PCC selected as D2 and three dedicated secondary carrier SCC options (D3, D7, and D8), selecting a carrier with good signal quality and low load as the dedicated secondary carrier is a key technology. Intelligent carrier selection must address both the problem of selecting a low-load dedicated secondary carrier SCC and the problem of reducing the overhead of inter-frequency measurements during carrier aggregation initiation. When a user terminal initially accesses the network, during carrier aggregation (CA) configuration, three main factors are considered: bandwidth, cell load, and user spectral efficiency. Cell bandwidth information can be obtained by the user during initial network access and inter-frequency measurements; cell load is known from the serving cell as the primary carrier, while the neighboring cell load of the dedicated secondary carrier to be configured can be obtained through X2 interface interaction; the selectable dedicated secondary carrier spectral efficiency can be calculated using a preset virtual grid.

[0060] Figure 4A flowchart illustrating a method for generating a preset virtual grid, as provided in an embodiment of this application, is shown below. Figure 4 As shown, the methods for generating a preset virtual grid may include:

[0061] Step 301: Perform artificial intelligence learning based on the measurement report reported by the user terminal to generate different grids including wireless signal characteristics and user terminal information;

[0062] Step 302: Cluster different grids with the same wireless signal characteristics into the same grid to obtain a preset virtual grid, wherein the wireless signal characteristics include user spectral efficiency and the user terminal information includes the beam information of the user terminal.

[0063] Figure 5 This is a schematic diagram of a preset virtual grid provided in an embodiment of this application. Figure 5 Each grid in the system possesses radio characteristics serving both local and inter-frequency points within the cell: same-frequency RSRP, inter-frequency RSRP, and user spectral efficiency. The generation process of the preset virtual grid may include: the base station eNodeB performs AI learning over a long period based on MR reports reported by user terminals (UEs) to generate grids with different radio signal characteristics and user terminal information. Users with the same radio characteristics are clustered in the same grid. Each grid contains both radio signal characteristics and user terminal information, including beam information. When a user accesses the base station, the beam information is used to index the corresponding grid in the preset virtual grid. The base station directly extracts the inter-frequency RSRP and spectral efficiency from the grid and selects the optimal dedicated secondary carrier based on the spectral efficiency.

[0064] Understandably, when a user terminal camps on the primary carrier, the base station can select the carrier combination that can provide the user with the maximum downlink throughput based on bandwidth, carrier load, and the user spectral efficiency predicted by the preset virtual grid. For example, if the user spectral efficiency predicted by the preset virtual grid is as follows: carrier D7 has high spectral efficiency and low PRB utilization; carrier D3 has medium spectral efficiency and medium PRB utilization; and carrier D2 has medium spectral efficiency and high PRB utilization, then the spectral efficiency [D2+D7] > [D2+D3] can be obtained. In this case, the carrier combination [D2+D7] is selected for carrier aggregation. According to the dedicated secondary carrier selection scheme, the user can directly enter the dedicated secondary carrier for rapid traffic offloading, thus realizing the rapid configuration and scheduling of the dedicated secondary carrier.

[0065] Figure 6 A flowchart illustrating another uplink carrier under interference configuration method provided in this application embodiment is shown below. Figure 6 As shown, the configuration method for the uplink carrier subject to interference may also include:

[0066] Step 102: Set a timer to periodically activate the dedicated secondary carrier so that the dedicated secondary carrier remains active.

[0067] In the above configuration method, after obtaining the scheme of the dedicated secondary carrier selection, you can directly enter the dedicated secondary carrier for rapid diversion. In the absence of water flow, you can set a timer to keep the dedicated secondary carrier active for a period of time, reduce the frequency of the dedicated secondary carrier SCC deactivation and reactivation, and improve the utilization rate of the dedicated secondary carrier.

[0068] For example, when the traffic on a dedicated secondary carrier is zero within a time interval Δt, the base station performs the operation of deleting the dedicated secondary carrier. After setting a timer, the time interval Δt is lengthened. This increased Δt time reduces the number of times the SCC is deleted, keeping the dedicated secondary carrier active for a period of time. After setting the timer, the configuration time for the dedicated secondary carrier is significantly reduced. The configuration time for the dedicated secondary carrier, which was originally 1-3 seconds, is increased to 180ms; the configuration time for the dedicated secondary carrier, which was originally 8ms-16ms, is increased to nearly 0s; and the configuration time for the dedicated secondary carrier, which was originally 3ms, is increased to nearly 0s. It is evident that after setting the timer, the dedicated secondary carrier can be quickly activated and configured during carrier aggregation, enhancing its traffic offloading capability.

[0069] The following is the technical verification work based on the above-mentioned configuration method for the interfered carriers, mainly including the following points: setting a four-quadrant strategy, carrying out dedicated auxiliary carrier transformation according to the four-quadrant strategy, and evaluating the effect using network-wide testing, CQT (Call Quality Test, also referring to testing the performance of wireless data networks at fixed locations), and experience testing. The transformation strategies for the four scenarios are roughly as follows: Scenario 1: Low load, low interference: D1 / D2 are decommissioned for NR use, and D3 / D7 / D7 are used for PCC. Scenario 2: Low load, high interference: D2 is used for PCC, and D3 / 7 / 8 are used for SCC, without adding new SCC cells. Scenario 3: High load, low interference: D2 / D3 are used for PCC, and D7 / 8 are used for SCC, requiring the addition of new SCC cells on the original basis. Scenario 4: High load, high interference: D1 / D2 are used for PCC, and D3 / 7 / 8 are used for dedicated SCC, requiring the addition of one new SCC cell on the original basis. The technical test area was selected in a 1-square-kilometer area at the border of Shenzhen and Hong Kong, involving about 50 sites, with received interference ranging from -110dBm to -85dBm. Frequency shifting, CA configuration, dedicated secondary carrier configuration, intelligent secondary carrier selection configuration, and timer configuration were performed on the affected cells according to a four-quadrant strategy.

[0070] To evaluate the actual speed change before and after optimization, a fixed-point Speedtest comparison test was conducted at the Shenzhen Fubao Philips RD-HLH site. At the same location, the downlink speed increased from 17.4Mbps to 60.6Mbps, a 3.5-fold increase in user speed, proving that the D3 / D7 frequency points interfered with by Hong Kong can be used as a dedicated secondary carrier via CA.

[0071] In the test area, 50-80% of users entered CA state, the secondary carrier diversion rate was 20-40%, and the downlink experience rate improved by over 40% during busy hours. The network also demonstrated improvements in uplink busy-hour experience rate, network utilization, and interference indicators in the verification area. Using a dedicated SCC, uplink services were deployed on the D2 carrier. Compared to the interfering D3 carrier, the uplink experience rate improved from 2Mbps to 10Mbps, a satisfactory improvement.

[0072] From the perspective of call statistics KPI indicators: Before the upgrade: D1 / D2 and D3 basically did not attract users due to high interference; After the upgrade: Option 1: D1 / D2 as PCC, D3 / 7 as SCC (20w / SCC); Option 2: D1 / D2 as PCC, D3 as SCC (40w / SCC). The uplink interference of D3 / D7 carriers is high, which seriously affects the experience of uplink users. After the upgrade to SCC, users mainly stay on D1 / D2, and the uplink experience rate is significantly improved; After the upgrade of D3 / 7 to SCC, the average downlink experience rate is improved by 8→12 Mbps (50% gain); The proportion of CA users on D1 / D2 PCC carriers is over 55%; Dedicated SCC traffic offloading ratio: about 22% traffic offloading on a single SCC carrier; The traffic after the upgrade can be kept basically the same as before.

[0073] In summary, the uplink interference carrier configuration scheme can not only improve the 4G network user experience, but also save 20M of 4G spectrum for 5G deployment, which can improve the 5G user experience by more than 30%.
