DETAILED DESCRIPTION

[0012] The embodiments of the present specification provide a carrier configuration method and a base station.

[0013] In order for those skilled in the art to better understand the technical solutions in the present specification, the technical solutions in the embodiments of the present specification will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present specification. Obviously, the described embodiments only represent some embodiments of the present specification, rather than all embodiments. Based on the embodiments in the present specification, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present specification.

[0014] The embodiment of the present specification provides a carrier configuration method and a base station. Since the number of devices to be configured is large and the carrier situation is complex, manually determining the effective secondary carrier and performing secondary carrier configuration has the problem of poor configuration efficiency and accuracy, resulting in low carrier aggregation effect of the base station. In actual application, the effective secondary carrier can also be screened through a static threshold. For example, the static threshold can be determined based on a threshold value of -105 dBm and a bias of 1 dB. The secondary carrier with a signal quality greater than the static threshold can be determined as an effective secondary carrier. However, first, since the coverage distances of carriers of different frequency bands are quite different, for example, the coverage range of the n28 (700 MHz) frequency band carrier is larger than that of the n41, n79 and other frequency band carriers. If the threshold for adding a secondary carrier in a 3CC carrier aggregation scenario is set to the above static threshold, multiple n28 cells will be detected in a multi-carrier scenario, and the static threshold cannot select the optimal n28 cell, and cannot truly play the role of 3CC carrier aggregation. Secondly, the n28 frequency band is used as a basic coverage layer in 5G network planning, and is used for deep coverage or wide area coverage scenarios. Therefore, the PRB utilization rate of the n28 frequency band carrier cannot be too high. However, if the threshold for adding a secondary carrier in 3CC is set to a uniform value (i.e., the static threshold), the probability of adding an n28 carrier will be increased, and the utilization rate will be increased, thereby affecting the use perception of the basic coverage layer. Therefore, the embodiment of the present specification provides a technical solution for improving the efficiency and accuracy of secondary carrier configuration to improve the carrier aggregation effect of the base station. In this solution, the network coverage area can be rasterized, the signal quality of each frequency band in each grid and the number of user equipment in each grid are determined, a target grid that meets a preset carrier aggregation condition is selected from the grids of the network coverage area, the target grid is clustered to obtain a cluster, the threshold value of each frequency band is determined according to the signal quality of each frequency band in the target grid corresponding to the cluster, the effective secondary carrier of each frequency band in the cluster is determined based on the threshold value of each frequency band, and the user equipment in the cluster is configured with a secondary carrier through the effective secondary carrier. In this way, by screening the target grid and clustering the target grid, the area where users are concentrated and the number of initiated services is large (i.e., the area corresponding to the cluster) can be found. Then, for the selected area, the threshold value of each frequency band can be determined according to the signal quality of each frequency band in the area, and the effective secondary carrier of each frequency band can be selected based on the threshold value, thereby avoiding the problem of low efficiency and accuracy of determining the effective secondary carrier caused by screening the effective secondary carrier through the static threshold, and improving the carrier aggregation effect of the base station. The specific processing can be referred to the specific content in the following embodiments.

[0015] As shown in the Figure 1 The embodiment of the present specification provides a carrier configuration method, which can be applied to a base station. The method can specifically include the following steps: In step S102, the network coverage area is rasterized.

[0016] The network coverage area can be a network coverage area of a specified network side device. The network side device can be a device for communicating with a mobile device. The network side device can be an Evolutional NodeB (eNB or eNodeB) or an access point in LTE, or a base station in a 5G network, a network side device in a future 6G network, or a network side device in a future evolved Public Land Mobile Network (PLMN) network. In implementation, the grid size (such as 50m*50m, 100m*100m, 2000m*2000m, etc.) can be determined according to the size of the network coverage area, carrier aggregation requirements, regulation priorities, etc., and the network coverage area can be rasterized according to the grid size to divide the network coverage area into multiple grids.

[0017] Alternatively, the network coverage area can also be rasterized by 5G Measurement Report (MR), 4G Minimization of Drive-Test (MDT), and Geographic Information System (GIS). For example, 5G MR data can be associated with 4G MDT data to generate 5G MR sampling points carrying latitude and longitude information, and the sampling points can be associated with geographic grids of GIS electronic maps. The specific implementation steps can be as follows: (1) Extract fields in 4G MDT data, such as eNBid, ScRSRP, ScEarfcn, ScPCI, ScTadv, ScAOA, NcEarfcn, NcPCI, NcRSRP, latitude and longitude information, and fields in 5G MR data, such as gNBid, ScRSRP, ScEarfcn, ScPCI, ScTadv, ScAOA, NcEarfcn, NcPCI, NcRSRP.

[0018] (2) Preprocess the extracted fields, associate the parameters and the adjacent area information, and use the 4 / 5G co-site information table to associate the 4G cells and 5G cells in the same sector. (3) Construct a fingerprint library containing the signal quality of each sampling point according to the reference signal receiving power (RSRP) of the serving cell and the neighbor cells of all sampling points in the grid: GeoHash = (ScCGI, ScRSRP, [NcCGI1, NcRSRP1], …, [NcCGIn, NcRSRPn]).

[0019] Then, the 5G MR sampling points carrying the latitude and longitude information can be associated with the geographic grid of the GIS electronic map. As can be used with 4G MDT information, the 4G cells in the fingerprint library are corresponded to the associated 5G cells, the latitude and longitude information of the identification (CGI) of the 4G cell is associated with the grid of the GIS electronic map, and at the same time, the association of the 5G cell and the GIS grid is also completed, and the grid processing of the network coverage area is realized.

[0020] In step S104, based on the signal quality of each frequency band in each grid and the number of user equipment in each grid, a target grid satisfying a preset carrier aggregation condition is selected from the grids of the network coverage area.

[0021] The carrier aggregation condition can be set according to the actual situation, for example, the corresponding carrier aggregation condition can be set according to the experience of experts, or a large amount of historical data can be statistically analyzed to determine the corresponding carrier aggregation condition.

[0022] In implementation, based on the frequency bands configured by each base station in the grid, the signal quality of each frequency band in the grid and the number of user equipment in each grid, it can be judged whether the grid satisfies the preset carrier aggregation condition, so as to select the area in the network coverage area where the user aggregation exists, the business is initiated more and the carrier aggregation can be performed, that is, to select the target grid.

[0023] In step S106, the target grid is clustered to obtain a cluster.

[0024] In implementation, a preset clustering algorithm (K-means algorithm, DBSCAN algorithm, etc.) can be used to cluster the target grid according to the position information of the target grid to obtain the cluster.

[0025] In step S108, according to the signal quality of each frequency band in the target grid corresponding to the cluster, the threshold value corresponding to each frequency band is determined.

[0026] In implementation, in the cluster The sampling points can be arranged by frequency band, and the last n% sampling points from strong to weak are selected, the sampling point is marked, and the RSRP value thereof is taken as the threshold value of the frequency band. The specific steps are as follows. Assuming that the number of sampling points contained in a certain frequency band in the target grid is N, the sampling point set can be: The RSRP of each sampling point can be used, that is, S can be sorted from high to low according to the RSRP intensity to obtain an ordered sequence:

[0027] The last n% of sampling points in the ordered sequence can be selected, that is, if n = 5, the last 5% of sampling points can be selected, and assuming that the number of sampling points corresponding to the last n% is k, the ceiling function can be used to ensure that at least n% is selected: The last k sampling points in the sorted sequence are selected, that is, the index range can be [N-k+1, N], and the formula is generated:

[0028] That is: Wherein, The sampling points selected for each frequency band are:

[0029] The RSRP of each frequency band selected sampling point can be used to determine the threshold value corresponding to the frequency band, such as the mean (or minimum, maximum, etc.) of the RSRP of the selected sampling points, which is determined as the threshold value corresponding to the frequency band.

[0030] In step S110, based on the threshold value corresponding to each frequency band, the effective secondary carrier corresponding to each frequency band in the clustering cluster is determined, so as to perform secondary carrier configuration processing on the user equipment in the clustering cluster through the effective secondary carrier.

[0031] In implementation, in order to provide higher service rate, the R15 protocol of 3GPP proposes the requirement that the NR user supports the maximum bandwidth up to 1GHz. Due to the scene that the operator may not have complete spectrum resources or the spectrum available to the operator is greater than the single carrier bandwidth capability defined by the protocol, the carrier aggregation (CA) function can be introduced, that is, multiple continuous or non-continuous component carriers (CC) can be aggregated into a larger bandwidth. One of the key technologies of 5G A network is 3CC carrier aggregation.

[0032] 5G network planning can include multiple frequency bands, such as 700MHz frequency band of n28, 2.6GHz frequency band of n41, 3.5GHz frequency band of n78, 4.9GHz frequency band of n79, etc. The bandwidth combination corresponding to different frequency band combinations can be as shown in Table 1.

[0033] Table 1

[0034] 3CC combination scheme is a combination of 3 carriers, and the 3CC rate is the sum of the downlink rates of the 3 carriers (downlink CA rate). In the case that the user equipment does not support uplink CA, the uplink rate of the user equipment is the uplink rate of the primary carrier. The peak rate of each frequency band combination in the above Table 1 can be shown in Table 2 as follows.

[0035] Table 2

[0036] In the carrier aggregation under the 3CC (i.e. three-carrier aggregation) combination scheme, there are primary cells and secondary cells, wherein the primary cell PCell (Primary Cell) is a cell in which the user equipment resides, and the operation of the user equipment in the cell is the same as that in a single-carrier cell.

[0037] The secondary cell SCell (Secondary Cell) is a cell configured to the user equipment by the base station through RRC connection signaling. The SCC (secondary carrier) can provide more wireless resources for the user equipment. The secondary cell SCell can have only downlink or both uplink and downlink.

[0038] Correspondingly, the primary carrier PCC is the Primary CC, i.e. the carrier corresponding to the primary cell PCell, and the secondary carrier SCC is the Secondary CC, i.e. the carrier corresponding to the secondary cell SCell.

[0039] For the user equipment that has implemented carrier aggregation, it can be determined whether the secondary carrier configured for the user equipment is a valid secondary carrier corresponding to the frequency band. In the case that the secondary carrier configured for the user equipment is not a valid secondary carrier corresponding to the frequency band, the secondary carrier configured for the user equipment is replaced by a valid secondary carrier.

[0040] Alternatively, for the user equipment that needs to perform carrier aggregation, the secondary carrier of the user equipment in the cluster can be configured according to the valid secondary carrier and the frequency band combination corresponding to the user equipment.

[0041] In addition, in the case that there are multiple valid secondary carriers corresponding to the same frequency band, the base station can perform secondary carrier configuration processing on the user equipment according to the discovery time of the valid secondary carriers corresponding to the same frequency band, or the base station can randomly select one valid secondary carrier from the valid secondary carriers to perform secondary carrier configuration processing on the user equipment.

[0042] The embodiment of the present specification provides a carrier configuration method, which can perform raster processing on a network coverage area, filter target grids meeting preset carrier aggregation conditions from the grids of the network coverage area based on signal quality of each frequency band in each grid and the number of user equipment in each grid, perform clustering processing on the target grids to obtain a clustering cluster, determine a threshold value corresponding to each frequency band according to the signal quality of each frequency band in the target grid corresponding to the clustering cluster, determine an effective secondary carrier corresponding to each frequency band in the clustering cluster based on the threshold value corresponding to each frequency band, and perform secondary carrier configuration processing on user equipment in the clustering cluster through the effective secondary carrier. In this way, by filtering the target grids and performing clustering on the target grids, an area (i.e., an area corresponding to the clustering cluster) where user equipment is concentrated and more services are initiated can be found, and then for the selected area, the threshold value corresponding to each frequency band can be determined according to the signal quality of each frequency band in the area, so as to filter the effective secondary carrier corresponding to each frequency band based on the threshold value, thereby avoiding the problem of low efficiency and accuracy of determining the effective secondary carrier caused by filtering the effective secondary carrier through a static threshold, and improving the carrier aggregation effect of the base station.

[0043] In actual application, the specific processing manner of filtering the target grids meeting the preset carrier aggregation conditions from the grids of the network coverage area based on the signal quality of each frequency band in each grid and the number of user equipment in each grid in the step S104 can be various, and an optional processing manner is provided as follows. Figure 2 As shown in the figure, the specific processing can include the following steps S1042-S1044.

[0044] In the step S1042, the signal quality of each frequency band in each grid is determined according to the reference signal received power of the user equipment corresponding to each frequency band in each grid.

[0045] In implementation, the mean value (or minimum value, maximum value, etc.) of the reference signal received power of the user equipment corresponding to each frequency band in each grid can be determined as the signal quality of each frequency band in each grid.

[0046] In the step S1044, the target grids meeting the preset carrier aggregation conditions are filtered from the grids of the network coverage area based on the frequency band type and the number of frequency bands contained in each grid, the signal quality of each frequency band in each grid, and the number of user equipment in each grid.

[0047] The carrier aggregation condition can include one or more of a quality condition, a quantity condition, and an aggregation condition. The quality condition can be used to measure whether the grid meets the signal quality requirement according to the signal quality of each frequency band in the grid. The quantity condition can be used to measure whether the grid meets the user quantity requirement according to the number of user equipment in the grid. The aggregation condition can be used to measure whether the grid meets the carrier aggregation requirement according to the frequency band type and the number of frequency bands contained in the grid.

[0048] In implementation, the processor can calculate the RSRP value of the MR sampling point of each grid by frequency band, to filter, according to the RSRP value of the sampling point, the effective grid (i.e., the target grid that meets the aggregation condition, the quality condition, and the quantity condition) that meets the 3CC condition (i.e., aggregation) while the signal quality of each frequency band is higher than the quality threshold and the number of sampling points (i.e., the number of user equipment in the grid) is higher than the quantity threshold.

[0049] First, the processor can calculate the RSRP value of the 5G multi-carrier by frequency band. Specifically, for the case of 5G network multi-frequency band networking, the 5G network standard, frequency band information, and frequency point, PCI, bandwidth, base station latitude and longitude information, antenna azimuth, downtilt angle, and other information corresponding to the frequency band can be collected. The collected information can be as shown in Table 3: Table 3

[0050] Based on the information collected in Table 3 above, the frequency band and SSB frequency point corresponding to each MR sampling point can be calculated. For example, the frequency band (such as n28, n41, n79, etc.) to which the sampling point belongs can be calculated from the frequency point information corresponding to the sampling point.

[0051] For example, taking the ARFCN calculation method corresponding to the center frequency 2565 MHz as an example, the calculation method in this example can be: NARFCN=2565MHz×10005kHz=513000NARFCN=5kHz2565MHz×1000=513000 The SSB frequency point can be determined by the synchronization grid (Synchronization Raster), and the step size is 1.44 MHz in C-Band (n41). The corresponding GSCN (Global Synchronization Channel Number) needs to be converted by the formula: fSSB=1200×N+50×M(kHz)fSSB=1200×N+50×M(kHz) Wherein, NNand MMare integers, and M∈{1,2,3}M∈{1,2,3}.

[0052] Alternatively, taking the SSB frequency point corresponding to GSCN=6312 as an example, the calculation method can be as follows: fSSB=1200×2104+50×3=2524.95MHzfSSB=1200×2104+50×3=2524.95MHz Convert it to ARFCN: NSSB=2524.95MHz×10005kHz=504990NSSB=5kHz2524.95MHz×1000=504990 Wherein, the calculation method of each ARFCN center frequency can be as follows: I. Basic parameters of n41 frequency band Frequency range: 2496-2690 MHz, bandwidth is 100 MHz.

[0053] Subcarrier spacing (SCS): 30 kHz can be used in large bandwidth scenarios, and 15 kHz can be used in other scenarios.

[0054] ARFCN range: 15kHz SCS: ARFCN range is 499200-537999, step size is 3.

[0055] 30kHz SCS: ARFCN range is 499200-537996, step size is 6.

[0056] For example: the center frequency corresponding to ARFCN 513000 can be 2565 MHz (2565 = 2496 + 0.1*(513000-499200)).

[0057] II. Calculation method of SSB frequency point number 1. Relationship between ARFCN and frequency Formula: FDL=FDL_low+0.1×(NARFCN-Noffset) Parameters: FDL_low=2496MHz (start frequency of n41 frequency band).

[0058] Noffset=499200 (ARFCN corresponding to 2496 MHz).

[0059] Example: NARFCN=513000→FDL=2496+0.1×(513000-499200)=2565MHz.

[0060] 2. GSCN and SSB center frequency GSCN definition: GSCN can be used to mark the center frequency position of SSB, which needs to be aligned with the synchronization raster.

[0061] Formula: FSS_REF = FSS_Offs + 0.03 x (NGSCN - NSS_Offs) Parameters: FSS_Offs = 2496 MHz (n41 band synchronization raster starting frequency).

[0062] NSS_Offs = 6312 (corresponding to GSCN of 2496 MHz).

[0063] Example: NGSCN = 6312 → FSS_REF = 2496 + 0.03 x (6312 - 6312) = 2496 MHz.

[0064] 3. Relationship between SSB position and ARFCN The center frequency of SSB needs to be located within the carrier bandwidth and meet the channel raster requirement. For example, the SSB frequency point number of China Mobile in the n41 band is 504990 (corresponding to GSCN 6312), and the center frequency is 2496 MHz, which is located at the low end of the carrier, facilitating fast cell search617.

[0065] After determining the frequency band corresponding to the carrier of each user equipment, the processor can determine the type and number of frequency bands contained in each grid based on the frequency band corresponding to the carrier of each user equipment, and then filter out the grids that meet the 3CC condition according to the type and number of frequency bands contained in each grid. Then, based on the number of user equipments in each grid and the signal quality of each frequency band in each grid, the target grid that meets the preset quality condition and quantity condition is filtered out from the grids that meet the 3CC condition.

[0066] Among them, the 3CC condition can be that the type and number of frequency bands contained in the grid meet any one of the following frequency band combinations: Frequency band combination 1: 2.6 GHz (100 MHz bandwidth) + 2.6 GHz (60 MHz bandwidth) + 4.9 GHz (100 MHz bandwidth); Frequency band combination 2: 2.6 GHz (100 MHz bandwidth) + 2.6 GHz (60 MHz bandwidth) + 700 MHz (30 MHz bandwidth); Frequency band combination 3: 2.6 GHz (100 MHz bandwidth) + 700 MHz (30 MHz bandwidth) + 4.9 GHz (100 MHz bandwidth); Frequency band combination 4: 2.6GHz (100MHz bandwidth) + 4.9GHz (100MHz bandwidth) + 4.9GHz (60MHz bandwidth).

[0067] In addition, there can be a variety of different frequency band combinations. Different frequency band combinations can be selected according to the actual application scenario. This specification does not specifically limit this in the embodiments.

[0068] In this way, based on the frequency band type and number contained in each grid, the signal quality of each frequency band in each grid, and the number of user equipment in each grid, effective grids with user clusters, a large number of initiated services, and the ability to perform carrier aggregation can be selected. Effective secondary carriers can then be selected based on the selected effective grids. Furthermore, by configuring the secondary carrier selection threshold for multi-carrier aggregation (3CC) for the selected area, it is possible to avoid using excessively distant 5G cells that cross-area coverage as 3CC secondary carriers, thereby improving the configuration efficiency and effectiveness of carrier aggregation.

[0069] In practical applications, the specific processing method for clustering the target raster in step S106 above to obtain clusters can vary. The following provides one optional processing method, such as... Figure 3 As shown, the process may specifically include the following steps, S1062.

[0070] In step S1062, based on the preset number of clusters and the number of other target grids that have a preset proximity relationship with each target grid, the target grids are clustered to obtain clusters.

[0071] In implementation, target graticets can be clustered based on a preset number of clusters and the proximity relationships between them to obtain clusters. The proximity relationships can include direct adjacency or indirect adjacency.

[0072] For example, taking proximity relationships, including direct adjacency, as an example, Figure 4 As shown, for the grid Gird(i,j) in the j-th row and i-th column, the grids that are adjacent to it can include the grid Gird(i,j+1) in the j+1-th row and i-th column, the grid Gird(i,j-1) in the j-1-th row and i-th column, the grid Gird(i+1,j) in the j-th row and i+1-th column, and the grid Gird(i-1,j) in the j-th row and i-1-th column.

[0073] It can identify target rasters that have a neighboring relationship with each target raster, and construct clusters based on target rasters that have a neighboring relationship and whose number exceeds a preset clustering limit. For example, ... Figure 5As shown, assuming that the preset cluster number is 5, the target grid whose number of adjacent target grids exceeds 5 (i.e., the grid Gird(i,j) in the jth row and the ith column) and its adjacent target grids (i.e., the target grid Gird(i-1,j), the target grid Gird(i-1,j-1), the target grid Gird(i,j-1), the target grid Gird(i+1,j), and the target grid Gird(i+2,j)) can be constructed into a cluster.

[0074] In this way, the effective grids can be clustered to obtain a cluster with a large traffic volume and capable of carrier aggregation, so that carrier configuration processing can be performed on user equipment in the cluster, the carrier aggregation effect is improved, and resource waste is avoided.

[0075] In actual applications, the specific processing manner of the effective secondary carriers corresponding to each frequency band in the cluster can be various based on the threshold value corresponding to each frequency band in step S110. An optional processing manner is provided as follows. Figure 6 As shown, the specific processing can include the following steps S1102-S1104.

[0076] In step S1102, the carrier screening threshold corresponding to each frequency band is determined based on the threshold value corresponding to each frequency band and the offset value.

[0077] In implementation, the carrier screening threshold corresponding to each frequency band can be the sum of the threshold value corresponding to each frequency band and the offset value, where the offset value can be configured according to actual application scenarios, and the embodiments of the present specification do not make specific limitations thereto.

[0078] In step S1104, the secondary carriers corresponding to each frequency band in the cluster are screened based on the carrier screening threshold corresponding to each frequency band to obtain the effective secondary carriers corresponding to each frequency band in the cluster.

[0079] In implementation, the addition and deletion of secondary carriers in 3CC carrier aggregation are triggered by A5 and A2 events, where the A5 event refers to "the signal quality of the PCell becomes lower than threshold 1 and the signal quality of the neighboring area becomes higher than threshold 2". The threshold 1 of the A5 event in CA is fixed at -31dBm, and the threshold 2 can be determined by the parameters CaA5RsrpThld2 (threshold value) and CaSccA5RsrpThld2Offset (offset value). The CA can configure the SCell through the A5 event.

[0080] The threshold 2 of the A5 event of the CA, which represents the value of the RSRP trigger threshold 2 of the A5 event corresponding to the secondary cell of the CA. If the signal quality of the primary cell is lower than -31dBm, and the RSRP measurement value of the neighboring area is higher than the value of the threshold 2 (i.e., the sum of the threshold value and the offset), the UE will report the A5 event.

[0081] A2 event, refers to "SCell signal quality becomes lower than corresponding threshold", the threshold of A2 event in CA is determined by parameters CaA2RsrpThld (threshold value) and CaA2RsrpThldOffset (offset value). CA can exclude SCell with poor signal quality through A2 event.

[0082] The threshold 2 in the above-mentioned A5 event and the threshold in A2 can be the carrier screening threshold corresponding to each frequency band. The processor can trigger A5 and / or A2 events according to the carrier screening threshold to realize the secondary carrier configuration processing of the user equipment. Determining the threshold value corresponding to each frequency band in the case of combining the wireless environment of the cluster can avoid the problem of low efficiency and accuracy of effective secondary carrier screening caused by static threshold, improve the accuracy of secondary carrier configuration, and ensure user perception.

[0083] In actual application, the specific processing mode of the secondary carrier configuration processing of the user equipment in the cluster through the effective secondary carrier in the above-mentioned step S110 can be various, and the secondary carrier configuration processing can include secondary carrier adding processing. Correspondingly, an optional processing mode is provided below, as shown in the following figure. Figure 7 The specific processing can include the following steps S1106-S1108.

[0084] In step S1106, it is judged whether to add a secondary carrier for the user equipment based on the signal quality of the primary carrier of the user equipment in the cluster.

[0085] In implementation, the processor can determine that a secondary carrier needs to be added for the user equipment when the signal quality of the primary carrier of the user equipment in the cluster is lower than the preset primary carrier threshold (i.e. the threshold 1 in the above-mentioned A5 event).

[0086] In step S1108, in the case of determining to add a secondary carrier for the user equipment, the secondary carrier adding processing of the user equipment in the cluster is performed according to the effective secondary carrier corresponding to each frequency band.

[0087] In implementation, the processor can determine the frequency band to be added for the user equipment according to the frequency band combination supported by the cluster and the frequency band of the primary carrier of the user equipment, and obtain the effective secondary carrier corresponding to the determined frequency band to perform the secondary carrier adding processing of the user equipment through the effective secondary carrier.

[0088] For example, assuming that the frequency band of the primary carrier of the user equipment in the cluster is 2.6G (160M), and the frequency band combination supported by the cluster includes 2.6G (160M) + 700M (30M) + 4.9G (100M), then the processor can determine that the frequency bands of the secondary carriers that need to be added are 700M (30M) and 4.9G (100M), and the processor can perform secondary carrier addition processing on the user equipment according to the effective secondary carriers corresponding to 700M (30M) and 4.9G (100M) in the cluster.

[0089] In this way, in the case where it is determined that the user equipment needs to perform secondary carrier addition processing, the secondary carrier can be quickly and accurately added to the user equipment through the effective secondary carriers corresponding to each frequency band, the signal transmission quality is improved, and the carrier aggregation effect is achieved.

[0090] In actual application, the specific processing manner of performing secondary carrier configuration processing on the user equipment in the cluster through the effective secondary carriers in step S110 can be various, and the secondary carrier configuration processing can include secondary carrier deletion processing and / or secondary carrier addition processing. Accordingly, an optional processing manner is provided below, as shown in the following table. Figure 8 The specific processing can include the following steps S11010-S11012.

[0091] In step S11010, whether there is a target secondary carrier to be deleted in the secondary carriers of the user equipment is determined based on the threshold values corresponding to each frequency band and the signal quality of the secondary carriers of the user equipment in the cluster.

[0092] In implementation, the processor can determine the secondary carrier with a signal quality lower than the threshold (i.e., the sum of the threshold value and the bias value) of the corresponding frequency band as the target secondary carrier.

[0093] In step S11012, in the case where it is determined that there is a target secondary carrier in the secondary carriers of the user equipment, the target secondary carrier is deleted, and secondary carrier addition processing is performed on the user equipment through the effective secondary carriers.

[0094] In implementation, the processor can delete the target secondary carrier and add the effective secondary carriers to the user equipment as secondary carriers, which can improve the secondary carrier update efficiency, improve the resource utilization rate, and ensure that the user equipment can achieve high-quality data transmission.

[0095] In actual application, the specific processing manner of performing secondary carrier configuration processing on the user equipment in the cluster through the effective secondary carriers in step S110 can be various, and the secondary carrier configuration processing can include secondary carrier deletion processing and / or secondary carrier addition processing. Accordingly, an optional processing manner is provided below, as shown in the following table. Figure 9 The specific processing can include the following steps S11014-S11018.

[0096] In step S11014, in the case that the cluster corresponding to the user equipment to be configured includes multiple clusters, the valid secondary carriers of each cluster for the same frequency band are obtained.

[0097] In implementation, since multiple frequency bands can be included in the grid, and each frequency band can correspond to multiple gNodeB cells belonging to the frequency band, the coverage of the carrier of the n28 frequency band (700 MHz) is relatively far, and the same gNodeB cell can appear in several different grids, that is, the same cell can belong to multiple clusters, and then the user equipment in the cell corresponds to multiple clusters. In this case, the valid secondary carriers of each cluster corresponding to the user equipment for the same frequency band can be obtained.

[0098] In step S11016, based on the carrier configuration requirement of the user equipment to be configured, the valid secondary carriers of each cluster for the same frequency band are filtered to obtain the target valid secondary carriers corresponding to each frequency band.

[0099] The carrier configuration requirement can include carrier quality requirement, carrier quantity requirement, etc.

[0100] In implementation, taking the carrier quality requirement as an example, the processor of the base station can filter the valid secondary carriers according to the signal quality of the valid secondary carriers of each cluster for the same frequency band to obtain the target valid secondary carriers corresponding to each frequency band.

[0101] In addition, the carrier configuration requirement can be various, and different carrier configuration requirements can be configured according to actual application scenarios to filter the valid secondary carriers according to actual carrier configuration requirements.

[0102] Alternatively, the processor can also determine the target threshold value corresponding to each frequency band according to the threshold value of each cluster for the same frequency band, and filter the secondary carriers corresponding to the user equipment according to the target threshold value to obtain the target valid secondary carriers.

[0103] For example, the processor can determine the minimum value of the threshold value of each cluster for the same frequency band as the target threshold value corresponding to each frequency band, and filter the secondary carriers corresponding to the user equipment according to the target threshold value to obtain the target valid secondary carriers.

[0104] In step S11018, the secondary carrier configuration processing is performed on the user equipment to be configured through the target valid secondary carrier.

[0105] In implementation, in the case of associating multiple grid clusters with the same NR cell, the minimum value (or average value, etc.) of the threshold values corresponding to each frequency band in the grid cluster can be determined as the screening standard of the effective secondary carrier of each frequency band in the NR cell by associating the carriers of different frequency bands in the target grid with the NR cell, so as to perform secondary carrier configuration processing on the user equipment of the cells belonging to multiple clustering clusters, and improve the configuration efficiency and configuration effect of the secondary carrier.

[0106] In addition, the core value of 3CC of 5G is to break through the limitations of traditional networks in rate, latency and coverage through efficient aggregation of spectrum resources. Its application scenarios cover transportation, industry, livelihood, urban management and other fields, promoting digital transformation and intelligent upgrading. With further technology maturation, 3CC will play a greater role in emerging fields such as the Internet of Vehicles and the Metaverse. Here are its core application scenarios and specific analysis: 1. High-speed rail and transportation hub 3CC of 5G can solve problems such as Doppler effect, frequent base station switching and signal attenuation in the car caused by high-speed movement in the high-speed rail scenario. For example, by aggregating 2.6GHz, 4.9GHz and 700MHz frequency band resources, a super wide bandwidth (such as 260MHz) can be formed to achieve stable connection inside a high-speed train and support high-definition video, real-time entertainment and other services. Specifically, after deploying 3CC in high-speed rail, the rate can reach 1.2Gbps, which can meet the needs of 1080p video without lag. In commercial areas, 3CC can be used for contiguous coverage to improve network capacity in densely populated areas.

[0107] 2. Dense crowd area (tourist attraction, large event) In places with high concentration of people (such as scenic spots, stadiums, concerts), 3CC can improve network capacity by aggregating multiple carriers, support a large number of users to access simultaneously, achieve a downlink peak rate of more than 4Gbps, and guarantee the high-definition live streaming and interactive experience of tourists. In large event scenarios, 3CC technology can support a downlink rate of 4.2Gbps to handle instantaneous high traffic demand.

[0108] 3. Industry Internet (smart manufacturing, remote inspection) 3CC can provide low-latency, high-reliability connections for industrial scenarios, supporting smart manufacturing and remote control. For example, in the smart manufacturing scenario, 2.6GHz and 4.9GHz frequency bands can be aggregated to meet the bandwidth requirements of real-time monitoring of high-definition cameras and collaborative work of robots within the factory, improving production efficiency. In remote inspection scenarios in the power and energy industries, 3CC can support unmanned aerial vehicle high-definition video backhaul and remote control, reducing the risk of manual inspection.

[0109] 4. Remote areas and emergency communication In complex geographical conditions such as highlands and mountainous areas, 3CC can expand the coverage depth through low frequency bands (such as 700MHz), and improve the rate through high frequency bands. Through 3CC deployment, the network coverage problem in highlands can be solved, and applications such as remote medical treatment and AR teaching can be supported, thereby promoting the sinking of high-quality resources. In emergency rescue scenarios, the 3CC sensing integrated technology can locate the unmanned aerial vehicle or rescue equipment in real time, thereby improving the efficiency of emergency response.

[0110] 5. Smart City and Internet of Things The large bandwidth and low latency characteristics of 3CC can provide infrastructure support for smart cities, such as massive connections of Internet of Things: supporting high-density access of devices such as intelligent street lamps and environmental monitoring sensors, thereby improving the efficiency of urban management, and massive connections of vehicle networking: through low latency communication (URLLC), realizing real-time interaction between traffic lights, vehicles and the cloud, and optimizing traffic flow.

[0111] 6. Integration of Sensing and New Technologies 3CC can be combined with sensing integration technology to expand the dual capabilities of communication and sensing, such as realizing low-altitude unmanned aerial vehicle management: through base station reflection signal sensing of unmanned aerial vehicle trajectory, which can be applied to highland logistics and urban security scenarios, and VR / AR immersive experience, for example, based on the high bandwidth support provided by 3CC, the cultural VR project promotes the upgrading of the cultural and tourism industry.

[0145] In the 1990s, it was possible to distinguish whether an improvement in a technology was a hardware improvement (e.g., an improvement in the circuit structure of a diode, transistor, switch, etc.) or a software improvement (an improvement in a method flow). However, as technology has advanced, many improvements in method flows today can be considered as direct improvements in hardware circuit structures. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into a hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (e.g., a field programmable gate array (FPGA)) is an integrated circuit whose logic function is determined by user programming of the device. A digital system is "integrated" on a PLD by the designer programming it themselves, without having to ask a chip manufacturer to design and fabricate a custom integrated circuit chip. Moreover, instead of manually fabricating an integrated circuit chip, this programming is now mostly implemented using "logic compiler" software, which is similar to the software compiler used when developing a program, and the original code before compilation must also be written in a specific programming language, which is called a hardware description language (HDL), and there are many types of HDL, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., and the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that it is very easy to obtain a hardware circuit that implements a logical method flow by simply logically programming the method flow in one of the above-mentioned hardware description languages and programming it into an integrated circuit.

[0146] The controller can be implemented in any suitable way, for example, the controller can take the form of a microprocessor or processor and a computer readable medium storing computer readable program code, such as software or firmware, executable by the microprocessor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller and an embedded microcontroller, examples of which include but are not limited to the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20 and Silicone Labs C8051F320, the memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that, in addition to implementing the controller in pure computer readable program code, it is possible to implement the same functionality in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers and embedded microcontrollers by logically programming the method steps. Such a controller can therefore be considered to be a hardware component, and the means included therein for implementing the various functions can also be considered to be structures within the hardware component. Alternatively, or even additionally, the means for implementing the various functions can be considered to be both a software module implementing the method and a structure within the hardware component.
