However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art.

[0072] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale.

These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0073] In related technologies, there is no coordinated scheduling between TDD and FDD frequency bands, the user distribution between different frequency bands and the airspace load are unbalanced, and the spectrum utilization cannot be maximized, which seriously affects the overall performance and user experience under the TDD+FDD shared network, and cannot give full play to the advantages of TDD and FDD to provide better communication quality for terminals.

[0074] Based on this, an embodiment of the present disclosure provides a terminal access adjustment method based on an independent networking shared base station, the method comprising: obtaining detection reference signals of multiple terminals in the independent networking shared base station; the detection reference signals include detection reference signals in multiple narrow beams under the time division duplex shared base station and detection reference signals in the wide beam under the frequency division duplex shared base station, according to the detection reference signals of multiple terminals, determining the user distribution, beam occupancy and beam load of the independent networking shared base station, according to the user distribution, beam occupancy and beam load, adjusting the access status of the terminal in the wide beam and multiple narrow beams, which can improve spectrum utilization and coordinate the load conditions between the two frequency bands of TDD and FDD.

[0075] Figure 1 An independent networking shared base station 100 is shown, which includes a frequency division duplex shared base station 101, a time division duplex shared base station 102 and a beam coordinator 103.

[0076] Among them, the beam coordinator is used to obtain the sounding reference signals of multiple terminals in the independent networking shared base station; the sounding reference signals include the sounding reference signals in multiple narrow beams under the time division duplex shared base station and the sounding reference signals in the wide beam under the frequency division duplex shared base station. According to the sounding reference signals of multiple terminals, the user distribution, beam occupancy and beam load of the independent networking shared base station are determined; according to the user distribution, beam occupancy and beam load, the access status of the terminal in the wide beam and multiple narrow beams is adjusted.

[0077] In a possible embodiment, the frequency division duplex shared base station 101 in the independent networking shared base station 100 may include a sounding reference signal (SRS) wide beam. The time division duplex shared base station 102 may include 2*N SRS narrow beams.

[0078] According to the frequency band and bandwidth, it can be divided into the following two situations:

[0079] Case 1: 2.1G, 50M frequency division duplex shared base station 101 and 3.5G, 200M (100M+100M) time division duplex shared base station 102. Case 1 may be taken as an example in the following embodiments.

[0080] Case 2: a 700M (30 / 40M) frequency division duplex shared base station 101 and a 2.6G, 160M (100M+60M) time division duplex shared base station 102.

[0081] Here, N is used to represent the number of narrow beams, and can be 64, 128, or 256, etc., without any specific limitation.

[0082] It should be noted that the independent networking shared base station in the present disclosure may also include other situations. In the independent networking shared base station, the frequency division duplex shared base station and the time division duplex shared base station may be a shared base station or a non-shared base station, but an overlapping coverage area is required.

[0083] The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

[0084] First, an embodiment of the present disclosure provides a terminal access adjustment method based on an independent networking shared base station. The method can be executed by any electronic device with computing and processing capabilities. In the following process, the electronic device is taken as the beam coordinator 103 as an example.

[0085] Figure 2A flow chart of a terminal access adjustment method based on independent networking and sharing of base stations in an embodiment of the present disclosure is shown. Figure 2 As shown, the terminal access adjustment method based on independent networking shared base station provided in the embodiment of the present disclosure includes the following steps:

[0086] S202: Acquire sounding reference signals of multiple terminals in an independent networking shared base station, where the sounding reference signals include sounding reference signals in multiple narrow beams of a time division duplex shared base station and sounding reference signals in a wide beam of a frequency division duplex shared base station.

[0087] In a possible embodiment, through communication between the independent networking shared base station and the terminal, the independent networking shared base station can receive the SRS sent by each terminal.

[0088] Since there are overlapping coverage areas of the TDD shared base station and the FDD shared base station, the SRS includes SRSs sent by terminals of two types of base stations, the TDD shared base station and the FDD shared base station.

[0089] S204: Determine the user distribution, beam occupancy and beam load of the independent networking shared base station according to the sounding reference signals of the multiple terminals.

[0090] In a possible embodiment, user distribution, beam occupancy and beam load are determined by detecting reference signals.

[0091] Exemplarily, the user distribution is determined as follows: according to the arrival direction of the detection reference signal of each terminal, the arrival angle (Angle-of-Arrival, AOA) of the detection reference signal corresponding to each terminal is determined; the reference signal receiving power (Reference Singal Receiving Power, RSRP) in each detection reference signal is measured, and according to the arrival angle corresponding to each terminal and the mapping relationship between the reference signal receiving power and the distance, the location information of each terminal is determined in the polar coordinate system through the positioning algorithm, and according to the location information of each terminal, the user distribution of the independent network shared base station is determined.

[0092] After determining the user distribution, the location information of the terminal used by the user is known, which can be used to adjust the terminal access situation.

[0093] Exemplarily, the beam identifier corresponding to the detection reference signal sent by each terminal is obtained, and the beam belonging of each terminal is determined according to each beam identifier, and the beam occupancy of the independent networking shared base station is determined according to the beam belonging of each terminal.

[0094] The beam identifier can be understood as the Beam ID of the SRS beam.

[0095] The SRS sent by each terminal will carry a beam identifier. After the independent networking shared base station receives the SRS, it can identify the beam identifier and determine the beam to which the terminal belongs through the association between the terminal and the beam identifier. Each beam has a limit on the number of service terminals. Here, the maximum number of terminals that each beam can serve is M.

[0096] Beam occupancy can be understood as the number of terminals that have been served by each beam in all beams.

[0097] Exemplarily, the ratio of the number of terminals served on each beam to the maximum number of users served by each beam M. If this ratio is greater than or equal to the preset load threshold, it means that the load of this beam is heavy, and if it is less than the preset load threshold, it means that the load of this beam is light.

[0098] The beam load of the independent networking shared base station is determined based on the beam occupancy and the maximum number of terminals served by each beam.

[0099] The above-mentioned beam occupancy and beam load conditions include the occupancy and load conditions of wide beams under FDD shared base stations, and the occupancy and load conditions of narrow beams under TDD shared base stations.

[0100] S206: Adjust the access status of the terminal in the wide beam and multiple narrow beams according to the user distribution, beam occupancy and beam load.

[0101] In a possible embodiment, the present disclosure determines the distance between the user and the base station by the user distribution, and then adjusts the terminal access according to the beam occupancy and beam load conditions. Taking full advantage of the properties of the narrow beam under the TDD shared base station and the properties of the wide beam under the FDD shared base station, the TDD shared base station has the following advantages over the FDD shared base station: it can flexibly configure the frequency and use the scattered frequency bands that are not easy to use for FDD, and compared with the wide coverage of the wide beam, the narrow beam under the TDD shared base station can provide higher communication quality.

[0102] In a possible embodiment, in order to enable the terminal to obtain better communication quality, a portion of the terminals in the wide beam may be switched to the narrow beam. The specific adjustment method may be as follows: Figure 3 As shown, the following steps are included:

[0103] S302: According to user distribution, determine a first terminal whose distance to the time division duplex shared base station is less than a first preset distance and belongs to a wide beam of the frequency division duplex shared base station.

[0104] S304: According to the beam load and beam occupancy of the narrow beam, the first terminal is switched to the narrow beam to complete the adjustment of the terminal access situation.

[0105] Terminals that are relatively close to the TDD shared base station can switch to narrow beams near the terminal and perform communication transmission with better communication quality.

[0106] Exemplarily, the switching process may be: determining, according to the beam load condition of the narrow beam, a first narrow beam whose beam load is less than a preset load threshold under a time division duplex shared base station; determining, according to the beam occupancy condition of the narrow beam, the number of terminals that can be served by the first narrow beam from the current beam load reaching the preset load threshold; if the number of terminals that can be served is greater than or equal to the number of the first terminals, switching the first terminal to the first narrow beam to complete the adjustment of the terminal access condition; if the number of terminals that can be served is less than the number of the first terminals, selecting the first terminal whose current communication transmission rate in the wide beam is less than the preset rate to switch to the first narrow beam; selecting the second narrow beam whose physical layer time-frequency resource block occupancy rate is less than the preset occupancy rate from the narrow beam whose beam load is greater than the preset load threshold; switching the first terminal that failed to switch to the first narrow beam to the second narrow beam to complete the adjustment of the terminal access condition.

[0107] During the switching process, the first narrow beam with low load is preferentially selected, and it is determined whether the number of terminals that can be served by all beams with low load can meet the number of the first terminals before the load reaches the preset load threshold. If so, all the first terminals are directly switched to the first narrow beam.

[0108] If not, it is necessary to give priority to adjusting the terminals with poor communication quality, for example, you can choose the terminals with low communication transmission rate in the wide beam, or choose the terminals with large physical layer time-frequency resource block occupancy rate.

[0109] Then, from the narrow beams whose beam load is greater than the preset load threshold, select a second narrow beam whose physical layer time-frequency resource block occupancy rate is less than the preset occupancy rate, and switch the first terminal that fails to switch to the first narrow beam to the second narrow beam to complete the adjustment of the terminal access situation.

[0110] Furthermore, before the terminal is switched to a narrow beam, a second terminal capable of multi-user input and output (MU-MIMO) pairing can be predicted in the time division duplex shared base station. After the adjustment of the terminal access situation is completed, the first terminal and the second terminal are paired for multi-user input and output.

[0111] The total network throughput and total capacity can be significantly improved through multi-user input and output pairing, and the Internet access speed can be increased several times. The specific scenario of migrating the first terminal and performing multi-user input and output pairing of the first terminal and the second terminal can be as follows: Figure 4 As shown, it includes a beam coordinator, a time division duplex shared base station and a frequency division duplex shared base station. The beam coordinator executes the above method, migrates the first terminal to the narrow beam under the time division duplex shared base station to achieve communication, and pairs with the second terminal. Figure 4 The pairing in represents a multi-user input-output pairing. Figure 4 The arrow in the figure indicates the migration process, and the black terminal indicates the first terminal that has been migrated. Since it has been migrated to the narrow beam to realize communication, it is represented in black.

[0112] It should be noted that the migration in this disclosure does not refer to the migration of the terminal position, but the migration of the terminal from the original base station to another base station to achieve communication, which is the process of base station switching. In order to facilitate the understanding of the process of the terminal migrating from the frequency division duplex shared base station to the time division duplex shared base station, the migration process is reflected by arrows. Figure 4 The situation is the same as in , so no further elaboration is required.

[0113] Based on this, the multi-user input and output pairing capability of TDD shared base stations can be improved, beam coordination and overall scheduling can be achieved, the overall throughput, spectrum efficiency and user experience of the TDD+FDD shared network system can be improved, and the operation and maintenance optimization efficiency can be improved.

[0114] Exemplarily, the switching process for the first terminal can be understood as: preferentially selecting the first narrow beam whose beam load is less than the preset load threshold in the time division duplex shared base station; if the number of terminals that can be served by the first narrow beam before the beam load reaches the preset load threshold is greater than the number of first terminals, the switching process can be completed directly. If the number is insufficient, the first terminal with a low transmission rate is preferentially selected in the wide beam and switched to the first narrow beam. Then the second narrow beam is selected according to the occupancy rate of the physical layer time-frequency resource block until all the first terminals are switched.

[0115] In a possible embodiment, the terminal access situation can also be adjusted as follows: Figure 5 As shown, the following steps are included:

[0116] S502: According to the user distribution situation, determine a third terminal whose distance from the time division duplex shared base station is greater than a first preset distance and belongs to a narrow beam of the time division duplex shared base station.

[0117] S504: According to the beam occupancy and beam load of the wide beam, the third terminal is switched to the wide beam of the frequency division duplex shared base station.

[0118] For users who are far away from the TDD shared base station, when they complete communication under the TDD base station, not only the transmission rate is relatively low, but the narrow beams are numerous and narrow. Compared with the coverage of wide beams, the coverage of narrow beams will have poor signals in some areas, and some may even lose signals.

[0119] Based on this, the third terminal at a farther distance is switched from the narrow beam of the TDD shared base station to the wide beam, so that the 3.5G TDD shared independent networking base station can absorb and process more efficient terminals, realize the sharing and collaboration between the high-speed beam of the TDD shared base station and the medium and low-speed beam of the FDD shared base station, improve the overall system throughput, spectrum efficiency and user experience of the TDD+FDD shared network system, and improve the efficiency of operation and maintenance optimization.

[0120] It should be noted that terminals can be divided into high-efficiency terminals and low-efficiency terminals. For example, low-efficiency terminals may be some terminals that are far away from the TDD shared base station and have a transmission rate lower than 10 Mbps, while high-efficiency terminals are the opposite.

[0121] Exemplarily, in the process of switching the third terminal, a switching method can be selected to select a third terminal whose distance from the time division duplex shared base station is greater than a first preset distance and less than a second preset distance, and from the narrow beams to which the third terminals whose distance is greater than the first preset distance and less than the second preset distance belong, select a beam whose beam load is greater than a preset load threshold, and switch the third terminals corresponding to these beams to the wide beam.

[0122] The terminal is far away from the time division duplex shared base station, and the narrow beam to which it belongs is heavily loaded, which will make the terminal's transmission rate very low. Such a terminal can be called an inefficient terminal. Switch the inefficient terminal to a wide beam and communicate under the frequency division duplex shared base station. The wide beam of the frequency division duplex shared base station has a larger coverage range and higher communication quality. The switching of inefficient terminals can be called inefficient migration. The specific scenario can be as follows Figure 6 As shown, it includes a beam coordinator, a time division duplex shared base station and a frequency division duplex shared base station. The beam coordinator executes the above method to inefficiently migrate the third terminal, switching the third terminal from the original narrow beam under the time division duplex shared base station to the wide beam under the frequency division duplex shared base station. For ease of understanding, Figure 6 Arrows in the indicate inefficient migration.

[0123] When switching to a third terminal whose distance from the time-division duplex shared base station is greater than the first preset distance and less than the second preset distance, according to the beam occupancy of the wide beam, if the number of terminals that the wide beam can serve is sufficient, that is, the number of terminals that the wide beam can serve is greater than the number of third terminals and it can support switching of all third terminals at the same time, then all third terminals can be switched to the wide beam.

[0124] In a possible embodiment, if the number of terminals that can be served by the wide beam is not enough to switch all the third terminals, switching can be performed selectively.

[0125] Exemplarily, in the process of switching the terminal under the TDD shared base station to the wide beam, the switching method is as follows: according to the beam occupancy and beam load of the wide beam, the number of terminals that the wide beam can serve is determined, and according to the user distribution, the fourth terminal whose distance from the time division duplex shared base station is greater than the second preset distance is determined from the third terminal; if the number of terminals that the wide beam can serve is greater than the number of fourth terminals and less than the number of third terminals, the fourth terminal is switched to the wide beam; after the switching of the fourth terminal is completed, the remaining third terminals except the fourth terminal are switched to the wide beam.

[0126] The terminals may be divided into three types according to user distribution, namely: terminals with a distance less than a first preset distance, terminals with a distance greater than the first preset distance and less than a second preset distance, and terminals with a distance greater than the second preset distance.

[0127] Among them, the terminal that is less than the first preset distance can be switched from the wide beam to the narrow beam in the above manner. The terminal that is greater than the second preset distance indicates that the narrow beam may not be able to cover this type of terminal, and even under the narrow beam, the communication quality of the user communication transmission cannot be guaranteed. It can be switched to the wide beam. Migration of terminals with insufficient coverage can be called insufficient coverage migration. The specific scenarios of insufficient coverage migration can be as follows: Figure 7 As shown, it includes a beam coordinator, a time division duplex shared base station and a frequency division duplex shared base station. The beam coordinator executes the above method to migrate the fourth terminal to the wide beam. Figure 7 The arrows in indicate undercoverage migrations.

[0128] Among them, the specific switching method can be as follows: according to the beam occupancy of the wide beam, determine whether the number of terminals that the wide beam can serve is greater than the number of fourth terminals; if the number of terminals that the wide beam can serve is less than the number of fourth terminals, then determine the signal interference plus noise ratio when the fourth terminal transmits the signal according to the detection reference signal of the fourth terminal; switch the fourth terminal whose signal interference plus noise ratio is greater than the preset noise ratio threshold to the wide beam; if the fourth terminal whose signal interference plus noise ratio is greater than the preset noise ratio threshold is switched after the wide beam has a remaining number of services, then select a fourth terminal whose physical layer time-frequency resource block occupancy rate is greater than the preset occupancy rate from the fourth terminal that has not switched to the wide beam, and switch it to the wide beam.

[0129] Specifically, the switching of all third terminals can be understood as follows: if the wide beam can serve a sufficient number of terminals, then in a narrow beam whose beam load is greater than a preset load threshold, all terminals whose distance from the time division duplex shared base station is greater than a first preset distance and less than a second preset distance will be switched to the wide beam, and all terminals whose distance is greater than the second preset distance will also be switched to the wide beam.

[0130] If the number of terminals that can be served by the wide beam is insufficient, the terminals that are at a distance greater than the second preset distance from the time-division duplex shared base station will be switched first. The coverage range of such terminals is insufficient and communication may be interrupted at any time. Furthermore, among the terminals that are at a distance greater than the second preset distance from the time-division duplex shared base station, the terminals with a signal interference plus noise ratio greater than the preset noise ratio threshold are preferentially selected, and then the terminals with a high physical layer time-frequency resource block occupancy rate are selected. If the terminals that are at a distance greater than the second preset distance from the time-division duplex shared base station are switched to the wide beam, they can also be switched to the narrow beam whose beam load is greater than the preset load threshold and whose distance from the time-division duplex shared base station is greater than the first preset distance and less than the second preset distance.

[0131] In one possible embodiment, Figure 8 A terminal access adjustment method based on independent networking and sharing of base stations provided by an embodiment of the present disclosure is shown. Figure 8 As shown, the specific steps include:

[0132] S802: Acquire sounding reference signals of multiple terminals in an independent networking shared base station, where the sounding reference signals include sounding reference signals in multiple narrow beams of a time division duplex shared base station and sounding reference signals in a wide beam of a frequency division duplex shared base station.

[0133] S804: Determine the user distribution, beam occupancy and beam load of the independent network shared base station according to the sounding reference signals of multiple terminals.

[0134] S806: Determine whether the terminal is the first terminal that switches from the frequency division duplex shared base station to the time division duplex shared base station; if the terminal is the first terminal, execute S808; if not the first terminal, execute S812.

[0135] In a possible embodiment, the terminal switched from the frequency division duplex shared base station to the time division duplex shared base station may be understood as a first terminal whose distance from the time division duplex contributing base station is less than a first preset distance.

[0136] S808: Switching the first terminal to the narrow beam according to the beam load and beam occupancy of the narrow beam, thereby completing the adjustment of the terminal access situation;

[0137] S810: predicting a second terminal capable of multi-user input and output pairing in a time division duplex shared base station, and after completing adjustment of terminal access conditions, performing multi-user input and output pairing on the first terminal and the second terminal.

[0138] S812: Determine whether it is an insufficiently covered terminal; if so, execute S814; if not, execute S816.

[0139] In a possible embodiment, the third terminal is the terminal whose distance from the time division duplex contribution base station is greater than the first preset distance and less than the second preset distance, and the insufficient coverage terminal can be understood as the fourth terminal whose distance from the time division duplex contribution base station is greater than the second preset distance.

[0140] S814: Switch the insufficiently covered terminal from the narrow beam of the time division duplex shared base station to the wide beam of the frequency division duplex shared base station.

[0141] S816: Select a narrow beam whose beam load is greater than a preset load threshold, and does not need to be switched from the frequency division duplex shared base station to the time division duplex shared base station, and the terminal does not belong to insufficient coverage, and switch to the wide beam of the frequency division duplex shared base station.

[0142] It can be seen from the above embodiments that the terminal access adjustment method based on the independent networking shared base station provided by the present invention provides a coordination strategy for continuously and dynamically adjusting the beams under TDD and FDD according to the beam conditions and the distribution of users, and provides flexible beam coordination and overall scheduling for the different spatial distributions of users or traffic of the independent networking shared base station, thereby improving the overall performance of the TDD+FDD shared network system, improving the operation and maintenance optimization efficiency, and saving the operation and maintenance optimization costs, which has very important deployment significance and practical value.

[0143] It is also possible to carry out efficient coordinated scheduling between the various frequency bands of TDD and FDD, so that the user distribution and airspace load balance in different frequency bands of TDD and FDD, and the airspace multi-user input and output pairing capabilities are further released, so that more terminals can perform multi-user input and output pairing, significantly improving the total network throughput and total capacity, and increasing Internet access speeds. In addition, through the beam conditions and user distribution, as well as some other reference factors, the spectrum utilization can be maximized, thereby improving the comprehensive performance and user experience of independent networking shared base stations.

[0144] In another possible implementation, the transmission rate at which the terminal communicates with the base station under the independently networked shared base station can be obtained, the first target terminal whose transmission rate is less than the preset transmission rate is selected, and the beam load to which the first target terminal belongs is determined. Among them, the first target terminal whose distance from the time-division duplex shared base station is less than the first preset distance and belongs to the frequency-division duplex shared base station is switched to the time-division duplex shared base station. The first target terminal whose distance from the time-division duplex shared base station is less than the first preset distance and belongs to the frequency-division duplex shared base station is switched to the time-division duplex shared base station. The first target terminal whose distance from the time-division duplex shared base station is greater than the first preset distance and belongs to the time-division duplex shared base station is switched to the frequency-division duplex shared base station.

[0145] It can be understood that the terminal with poor communication quality under the original time division duplex shared base station and the original frequency division duplex shared base station will be served by another base station to improve the communication quality.
