[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] It should be noted that although the device schematics illustrate functional module divisions and the flowcharts illustrate logical sequences, in certain circumstances, the steps shown or described may be performed in a sequence that differs from the module divisions in the device or the sequence in the flowcharts. The terms "first," "second," and so on, in the specification, claims, and drawings, are used to distinguish similar items and are not necessarily used to describe a specific sequence or precedence.

[0029] The present invention provides a method and apparatus for controlling a terminal's residency in a network, and a readable storage medium thereof. By obtaining capability information of a terminal, a terminal that can utilize a Massive MIMO network to improve spectrum efficiency can be determined based on the capability information. That is, the terminal can be determined to be adapted for the Massive MIMO network. Therefore, the terminal can be selected to reside in the Massive MIMO network, thereby enabling the terminal to utilize the Massive MIMO network to improve its spectrum efficiency, thereby improving the overall communication performance of the Massive MIMO network.

[0030] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, Figure 1 It is a schematic diagram of a network architecture provided by an embodiment of the present invention.

[0032] Reference Figure 1 The network architecture includes a first base station 100 and a second base station 200. The first base station 100 corresponds to a Massive MIMO network, and the second base station 200 corresponds to a non-Massive MIMO network. Figure 1 In the network architecture shown, it can be clearly seen that the communication ranges of the Massive MIMO network and the non-Massive MIMO network overlap and cover each other. Based on this, the terminal 300 in the Massive MIMO network and the non-Massive MIMO network can be switched within the coverage area of ​​the two networks, which can enable the internal resources of the Massive MIMO network and the non-Massive MIMO network to be more reasonably allocated, thereby further optimizing the communication performance of the Massive MIMO network and the non-Massive MIMO network. It is worth noting that at present, due to the relatively low popularity of Massive MIMO networks, the overall scale of non-Massive MIMO networks in actual applications may be larger than that of Massive MIMO networks, but the communication speed and internal capacity of Massive MIMO networks are generally greater than those of non-Massive MIMO networks.

[0033] In one embodiment, the Massive MIMO network can be applied to, but is not limited to, a 5G communication system and a 4G communication system. When the Massive MIMO network is applied to a 4G communication system, it can be a time-division duplex massive multiple-input multiple-output (TDD Massive MIMO) network or a frequency-division duplex massive multiple-input multiple-output (TDD Massive MIMO) network.

[0034] In one embodiment, the second base station 200 may be, but is not limited to, a macro base station, a micro base station, a repeater, and the like.

[0035] The network architecture and application scenarios described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention and do not constitute a limitation on the technical solutions provided by the embodiments of the present invention.

[0036] It will be understood by those skilled in the art that Figure 1 The network architecture shown in the figure does not constitute a limitation on the embodiments of the present invention, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0037] The following specifically describes various embodiments of the method for controlling a terminal resident in a network provided by the present invention.

[0038] like Figure 2 As shown, Figure 2 This is a flow chart of a method for controlling a terminal resident network provided by an embodiment of the present invention, which can be applied to Figure 1 The network architecture shown in FIG. 1 includes but is not limited to the following steps:

[0039] Step S100, obtaining terminal capability information;

[0040] Step S200: determining, based on the capability information, a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency;

[0041] In step S300, a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency is placed in the Massive MIMO network.

[0042] In one embodiment, by obtaining capability information of the terminal and determining a terminal capable of improving spectrum efficiency in the Massive MIMO network based on the capability information, since the terminal has high spectrum efficiency, the terminal can achieve stable and good communication in the Massive MIMO network, thereby helping to improve the overall communication performance of the Massive MIMO network. Therefore, selecting the terminal to reside in the Massive MIMO network can improve the overall communication performance of the Massive MIMO network.

[0043] In one embodiment, the capability information of the terminal can be characterized separately by the characteristic parameters of the terminal itself, or by the combination of the characteristic parameters. Moreover, when characterizing, it can be considered based on the various transmission modes of the terminal, or based on other application scenarios or functional conditions of the terminal. This is not limited in the present invention.

[0044] In one embodiment, spectral efficiency is a basic term in a digital communication system, used to characterize the communication performance of a terminal in the digital communication system when performing communication transmission in the digital communication system. Generally speaking, the higher the spectral efficiency of a terminal, the more stable and reliable its transmission performance in the digital communication system, that is, the terminal is adapted to the digital communication system and suitable for residing in the digital communication system. Specifically, the spectral efficiency of a digital communication system is defined as the net bit rate or maximum throughput in the digital communication system divided by the bandwidth of the communication channel or data link, wherein the net bit rate here refers to the useful information rate and does not include error correction codes. In this embodiment, the digital communication system can be a Massive MIMO network or a non-Massive MIMO network.

[0045] In one embodiment, a terminal may utilize a Massive MIMO network to improve spectrum efficiency by utilizing the Massive MIMO network. This may be by utilizing the Massive MIMO network to improve the terminal's signal-to-noise ratio (SINR), that is, by improving the signal-to-noise ratio. Since an increase in the signal-to-noise ratio leads to a decrease in relative noise, a terminal with a higher signal-to-noise ratio is subject to less network interference, and thus its spectrum efficiency in the Massive MIMO network may be improved. Therefore, improving the signal-to-noise ratio to achieve improved spectrum efficiency may be used as a method for a terminal to utilize a Massive MIMO network to improve spectrum efficiency. It is worth noting that this embodiment only provides an example of utilizing a Massive MIMO network to improve spectrum efficiency. In fact, based on differences in Massive MIMO network characteristics and terminal capability information, other methods may be used to improve the terminal's spectrum efficiency. However, the basic principles are the same as those of this embodiment. Those skilled in the art may, based on the content of this embodiment, conceive of other similar methods for utilizing a Massive MIMO network to improve spectrum efficiency, which will not be described in detail here.

[0046] like Figure 3 As shown, Figure 3 Flowchart of a method for controlling a terminal resident network provided by another embodiment of the present invention, wherein before executing step S200, the method further includes the following steps:

[0047] Step S600: Determine a terminal with air separation capability based on capability information.

[0048] In one embodiment, spatial division capability is defined based on terminals in a Massive MIMO network. Specifically, if a Massive MIMO network can distinguish different data from the same terminal based on network spatial segmentation, allowing the same frequency band to be reused in different spaces, this is called spatial division multiplexing. Conversely, if a terminal can cooperate with spatial division multiplexing in a Massive MIMO network, it has spatial division capability; otherwise, it does not. Having spatial division capability means that a terminal can reuse the same frequency band in different spaces within the Massive MIMO network. Therefore, this indicates that the terminal can leverage the Massive MIMO network to improve spectral efficiency, meaning that the terminal has spatial division capability.

[0049] In one embodiment, step S600 may be performed in the following manner to determine whether the terminal has the air separation capability. Specifically:

[0050] The beamforming (BF) gain and number of spatial edges of the terminal can be obtained based on the capability information. When the BF gain is greater than a first gain threshold and the number of spatial edges is greater than a first edge threshold, the terminal is determined to have spatial edge capability. The number of spatial edges is defined as the number of terminals whose uplink transmission correlation with the current terminal is lower than a certain threshold. Assuming that there are a first terminal and a second terminal, if the uplink transmission correlation between the first terminal and the second terminal is lower than the first correlation threshold, it is determined that a spatial edge exists between the two terminals. That is, it can be determined that the number of spatial edges of the two terminals is the same as one. Correspondingly, on this basis, if there is also a spatial edge between the first terminal and another terminal, the number of spatial edges of the first terminal is two, and so on.

[0051] It is worth noting that the specific value of the first gain threshold can be obtained by actually measuring the characteristics of the Massive MIMO network, and the first edge number threshold can be set according to the correlation between the terminals in the Massive MIMO network, that is, the first gain threshold and the first edge number threshold can be set accordingly with the internal parameters of the Massive MIMO network. In this embodiment, their specific values ​​are not limited.

[0052] In one embodiment, step S600 may also be performed in the following manner to determine whether the terminal has the air separation capability, specifically:

[0053] The terminal's angle spread value is obtained based on the capability information. When the angle spread value is less than a first angle threshold, the terminal is determined to have space division capability. In one embodiment, since the terminal's angle spread is related to space division multiplexing, if a terminal has a large angle spread area, the terminal's communication space will be relatively large, which is not conducive to restricting space division multiplexing to a relatively limited communication space. Therefore, by determining the range of the terminal's angle spread value, terminals with angle spread values ​​that do not exceed a certain limit can be determined to have space division capability.

[0054] It is worth noting that the specific value of the first angle threshold can be obtained based on the characteristics of the Massive MIMO network. In this embodiment, its specific value is not limited. In addition, the determination method of this embodiment is applicable to terminals in various transmission modes. This embodiment can be performed, but is not limited to, in the following circumstances: determining when the terminal transmits based on the Space Frequency Block Code (SFBC) mode. It is worth noting that it is determined when the terminal transmits using the SFBC mode in the TM3 transmission mode, the TM4 transmission mode, or the TM9 transmission mode.

[0055] In one embodiment, step S600 may also be performed in the following manner to determine whether the terminal has the air separation capability, specifically:

[0056] The number of activated beams of the terminal is obtained based on the capability information. When the number of activated beams is less than a first beam threshold, the terminal is determined to have spatial division multiplexing capability. In one embodiment, since the number of activatable beams of a terminal is related to spatial division multiplexing, if a terminal has a large number of activatable beams, the communication space and range of the terminal will be relatively large, which is not conducive to restricting spatial division multiplexing to a relatively limited communication space. Therefore, by determining the number of activatable beams of the terminal, terminals with a number of activatable beams not exceeding a certain number can be determined to have spatial division capability.

[0057] It is worth noting that the specific value of the first beam threshold can be obtained based on the characteristics of the Massive MIMO network. In this embodiment, its specific value is not limited. Moreover, the determination method of this embodiment is applicable to terminals using various transmission modes. This embodiment can be performed, but is not limited to, in the following circumstances: determining when the terminal is transmitting based on the SFBC mode. It is worth noting that it is determined when the terminal is transmitting in the SFBC mode in the TM3 transmission mode, the TM4 transmission mode, or the TM9 transmission mode.

[0058] Furthermore, similar to the above embodiments, a specific execution method of step S200 may also be determined, thereby determining a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency based on the capability information. Specifically,

[0059] A downlink channel quality value (Channel Quality Indication, CQI) of the terminal is obtained based on the capability information. When the CQI is greater than a first channel quality threshold, it is determined that the terminal is capable of utilizing the Massive MIMO network to improve spectrum efficiency. In one embodiment, the CQI can be obtained through terminal measurement. The CQI is related to the sensitivity of the terminal, the transmission characteristics of the Massive MIMO network, etc., and can be used to characterize spatial division multiplexing. If the CQI of the terminal is relatively low, the communication sensitivity of the terminal and the transmission effect within the Massive MIMO network are relatively mediocre, and the terminal can no longer utilize the Massive MIMO network to improve spectrum efficiency. Therefore, by judging the CQI of the terminal, a terminal whose CQI exceeds a certain threshold can be determined as being capable of utilizing the Massive MIMO network to improve spectrum efficiency.

[0060] It should be noted that the specific value of the first channel quality threshold can be obtained according to the characteristics of the Massive MIMO network, and its specific value is not limited in this embodiment.

[0061] In one embodiment, step S200 may also be performed in another specific manner to determine, based on the capability information, a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency. Specifically,

[0062] The number of spatial division edges and the spatial division capability parameter of the terminal are obtained according to the capability information. When the number of spatial division edges is less than the second edge number threshold and the spatial division capability parameter is greater than the first threshold, it is determined that the terminal can use the Massive MIMO network to improve spectrum efficiency.

[0063] In one embodiment, the space separation capability parameter is the sum of the signal-to-noise ratio and the BF gain. When the number of space separation edges is less than a set second edge number threshold, that is, when the number of space separation edges is relatively small, it is only necessary to ensure that the space separation capability parameter is large enough, that is, the space separation capability parameter can be greater than the set first threshold. Then, it can be determined that the terminal can improve the spectrum efficiency through the signal-to-noise ratio.

[0064] In one embodiment, step S200 may also be performed in another specific manner to determine, based on the capability information, a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency. Specifically,

[0065] The number of spatial division edges and the spatial division capability parameter of the terminal are obtained based on the capability information. When the number of spatial division edges is less than a second edge number threshold, and the spatial division capability parameter is greater than the first threshold and less than the second threshold, it is determined that the terminal is capable of utilizing the Massive MIMO network to improve spectrum efficiency. In one embodiment, the number of spatial division edges indicates whether the terminal has spatial division capability. The spatial division capability parameter is the sum of the signal-to-noise ratio and the BF gain. The spatial division capability parameter corresponds to the CQI of the terminal and can be determined by the CQI of the terminal. The spatial division capability parameter indicates the terminal's ability to improve spectrum efficiency by improving the signal-to-noise ratio. In practice, if the spatial division capability parameter is small, the terminal cannot improve spectrum efficiency by improving the signal-to-noise ratio. Similarly, when the spatial division capability parameter of the terminal reaches a certain level, it is essentially saturated, and further increasing the signal-to-noise ratio will not improve the terminal's spectrum efficiency. Therefore, when the spatial division capability parameter is between the two thresholds, spectrum efficiency can be improved by improving the signal-to-noise ratio. Based on this, the number of spatial division edges and the spatial division capability parameter of the terminal can be determined to determine which terminal is capable of improving spectrum efficiency by utilizing the Massive MIMO network.

[0066] It's worth noting that the first threshold can be determined based on the number of antennas in a non-Massive MIMO network and the number of antennas in a Massive MIMO network corresponding to the terminal's maximum TBsize. Specifically, the first threshold is calculated by adding a conservative amount to the BF gain loss calculated based on the aforementioned data. This conservative amount can be obtained in actual communications and serves to mitigate channel shifting during network communications. The second threshold can also be obtained in actual communications, and its specific setting value must meet the terminal's basic channel quality requirements.

[0067] In one embodiment, step S200 may also be performed in another specific manner, so as to determine, based on the capability information, a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency. Specifically,

[0068] The terminal's angular spread value and BF gain are obtained based on the capability information. When the angular spread value is greater than a second angular threshold and the BF gain is greater than a first gain threshold, the terminal is determined to be capable of utilizing the Massive MIMO network to improve spectral efficiency. In one embodiment, when the BF gain is greater than the first gain threshold and the terminal's angular spread value is within a certain threshold, the terminal is determined to have spatial division capability. Based on this, it is only necessary to determine whether the angular spread value is greater than the second angular threshold to ensure that the terminal's angular spread is within a certain range, and thus the terminal is determined to be capable of utilizing the Massive MIMO network to improve spectral efficiency.

[0069] It is worth noting that the first gain threshold and the second angle threshold can be set accordingly based on the internal parameters of the Massive MIMO network. Their specific values ​​are not limited in this embodiment. Furthermore, the determination method of this embodiment is applicable to terminals operating in various transmission modes. This embodiment may be performed, but is not limited to, in the following circumstances: determining when a terminal is transmitting in a closed-loop spatial division multiplexing mode. It is worth noting that this determination may be performed when the terminal is transmitting in a closed-loop spatial division multiplexing mode, such as in the TM9 or TM10 transmission modes.

[0070] In addition, in one embodiment, a specific execution method of step S300 is also provided, so that terminals that can utilize the Massive MIMO network to improve spectrum efficiency are placed in the Massive MIMO network. Specifically:

[0071] When the number of terminals capable of utilizing a Massive MIMO network to improve spectrum efficiency exceeds a first number threshold, terminals with a signal-to-noise ratio greater than the first signal-to-noise ratio threshold are retained in the Massive MIMO network. In one embodiment, considering actual traffic, space, and other factors, the number of terminals that can be retained in a Massive MIMO network is generally limited. That is, too many terminals residing in the Massive MIMO network will adversely impact the Massive MIMO network. Therefore, by setting a first number threshold, a certain number of terminals capable of utilizing a Massive MIMO network to improve spectrum efficiency can be selected for retention. The retention condition is set to "a signal-to-noise ratio greater than the first signal-to-noise ratio threshold." That is, terminals that are more likely to improve signal-to-noise ratio and, therefore, spectrum efficiency, in the Massive MIMO network are preferentially retained. This allows terminals that are more suitable for retention in the Massive MIMO network to be retained while meeting the terminal retention requirements of the Massive MIMO network.

[0072] like Figure 4 As shown, Figure 4 1 is a flow chart of a method for controlling a terminal resident network provided by another embodiment of the present invention, wherein the method further includes:

[0073] Step S400: determining, based on the capability information, terminals that do not have a space division capability or cannot utilize a Massive MIMO network to improve spectrum efficiency;

[0074] Step S500: switching a terminal that does not have a space division capability or cannot utilize the Massive MIMO network to improve spectrum efficiency to a non-Massive MIMO network.

[0075] In one embodiment, capability information can be used to determine a terminal that does not have spatial division capability or cannot utilize a Massive MIMO network to improve spectrum efficiency. Since the terminal cannot improve spectrum efficiency in a Massive MIMO network, it does not contribute anything to the communication effect of the Massive MIMO network. However, the terminal will still occupy the internal space and resources of the Massive MIMO network, which is obviously not conducive to the overall communication of the Massive MIMO network. Therefore, the terminal can be switched to a non-Massive MIMO network, allowing the terminal to communicate in a more suitable non-Massive MIMO network, and also to release the internal space and resources of the Massive MIMO network. In addition, since the aforementioned embodiments have described in detail how to determine whether a terminal has spatial division capability and can utilize a Massive MIMO network to improve spectrum efficiency, based on the same principle, it is equivalent to determining a terminal that does not have spatial division capability or cannot utilize a Massive MIMO network to improve spectrum efficiency. To avoid redundancy, it will not be repeated here.

[0076] like Figure 5 As shown, Figure 5 This is a flow chart of a method for controlling a terminal resident network provided by another embodiment of the present invention, which can be applied to Figure 1 The network architecture shown, wherein the control method includes:

[0077] Step S700, obtaining terminal capability information;

[0078] Step S800: determining, based on the capability information, a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency;

[0079] Step S900: switching a terminal capable of utilizing the Massive MIMO network to improve spectrum efficiency to the Massive MIMO network.

[0080] In one embodiment, a non-Massive MIMO network can determine a terminal that can utilize the Massive MIMO network to improve spectrum efficiency based on capability information. The terminal can be a terminal that has always resided in the non-Massive MIMO network or a terminal that has been switched from the Massive MIMO network. In either case, the non-Massive MIMO network can determine that the terminal is more suitable for the Massive MIMO network. In comparison, the terminal is more suitable for residing in the Massive MIMO network. Therefore, it can be switched to the Massive MIMO network, allowing the terminal to communicate in the more suitable Massive MIMO network, and further releasing the internal space and resources of the non-Massive MIMO network. In addition, since the aforementioned embodiments have described in detail how to determine a terminal that can utilize the Massive MIMO network to improve spectrum efficiency based on capability information, and the basic ideas and architecture of this embodiment are the same as those of the aforementioned embodiments, to avoid redundancy, this embodiment will not be described in detail here.

[0081] like Figure 6 As shown, Figure 6 1 is a flow chart of a method for controlling a terminal resident network provided by another embodiment of the present invention, wherein the method includes:

[0082] Step S1000: determining, based on capability information, terminals that cannot utilize the Massive MIMO network to improve spectrum efficiency;

[0083] In step S1100, terminals that cannot utilize the Massive MIMO network to improve spectrum efficiency are placed in a non-Massive MIMO network.

[0084] In one embodiment, a non-Massive MIMO network obtains terminal capability information and, based on this capability information, determines a terminal that cannot improve spectrum efficiency in the Massive MIMO network. This means that the terminal is not suitable for residency in the Massive MIMO network. The network then selects the terminal to reside in the non-Massive MIMO network to ensure that the terminal's actual communication performance is met. This embodiment, based on the non-Massive MIMO network, enables reasonable residency of the terminal, thereby improving the communication performance of the non-Massive MIMO network.

[0085] like Figure 7 As shown, Figure 7 1 is a flow chart of a method for controlling a terminal resident network provided by another embodiment of the present invention, wherein the method further includes:

[0086] In step 1200, it is determined that it is impossible to determine whether the current terminal can use the Massive MIMO network to improve spectrum efficiency based on the capability information, and the current terminal is switched to the Massive MIMO network so that the Massive MIMO network determines whether the current terminal can use the Massive MIMO network to improve spectrum efficiency based on the capability information.

[0087] In one embodiment, for a certain terminal, if a non-Massive MIMO network cannot determine, based on capability information, whether the terminal can utilize the Massive MIMO network to improve spectrum efficiency, then this indicates that the non-Massive MIMO network does not have the capability to determine the terminal. Therefore, it is necessary to switch the terminal to a Massive MIMO network with stronger determination capability so that the Massive MIMO network can determine the terminal and prevent missed terminal determinations.

[0088] like Figure 8 As shown, Figure 8 1 is a flow chart of a method for controlling a terminal resident network provided by another embodiment of the present invention, wherein step S1000 includes:

[0089] S1001: Determine a terminal that does not have air separation capability based on capability information.

[0090] In one embodiment, if a terminal is determined to be without spatial division capability, it is obvious that it cannot utilize the Massive MIMO network to improve spectrum efficiency. Therefore, through the determination, it can be accurately determined that the terminal cannot utilize the Massive MIMO network to improve spectrum efficiency, so that the terminal can reside in a non-Massive MIMO network.

[0091] like Figure 9 As shown, Figure 9 1 is a flow chart of a method for controlling a terminal resident network provided by another embodiment of the present invention, wherein step S1000 includes:

[0092] S1002: Determine, based on the capability information, a terminal that has a space division capability and cannot utilize the Massive MIMO network to improve spectrum efficiency.

[0093] In one embodiment, after determining that a terminal has spatial division capability, it is further determined that it cannot utilize the Massive MIMO network to improve spectrum efficiency. Thus, the terminal that cannot utilize the Massive MIMO network to improve spectrum efficiency can be determined so that it can reside in a non-Massive MIMO network.

[0094] In addition, an embodiment of the present invention further provides steps after step S900, specifically:

[0095] The CQI of the terminal and the duration of residence in the non-Massive MIMO network are obtained according to the capability information. When the CQI is greater than the second channel quality threshold and the duration of residence in the non-Massive MIMO network is greater than the first duration, the terminal is switched to the Massive MIMO network. In one embodiment, a terminal in a non-Massive MIMO network may be its own terminal or a terminal switched from a Massive MIMO network. That is, terminals in the Massive MIMO network and the non-Massive MIMO network may switch between each other. In practice, it is generally not appropriate to immediately switch a terminal switched from a Massive MIMO network to the Massive MIMO network to avoid ping-pong switching of the terminal and unnecessary troubleshooting costs. Therefore, by determining the CQI of the terminal and the length of time the terminal has resided in the non-Massive MIMO network, a terminal whose channel quality has stabilized for a certain period of time after switching to the non-Massive MIMO network may be selected. At this time, the terminal has stable performance and can use the Massive MIMO network to improve spectrum efficiency, so it is switched to the Massive MIMO network.

[0096] In addition, an embodiment of the present invention further provides a control device for a terminal resident network, including a memory, a processor, and a computer program stored in the memory and executable on the processor.
