[0036] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0039] In order to provide higher service rates, the 3GPP R15 protocol proposes a requirement for NR users to support a maximum bandwidth of 1GHz. In scenarios where operators may not have complete spectrum resources and the operator spectrum is larger than the single carrier bandwidth capacity defined in the protocol, 3GPP introduces the Carrier Aggregation (CA) function, which aggregates multiple continuous or non-continuous component carriers (CCs) into a larger bandwidth to meet 3GPP's requirements and improve users' uplink and downlink peak rate experience.

[0040] According to the frequency band where the component carriers participating in carrier aggregation are located, carrier aggregation can be divided into intra-band carrier aggregation and inter-band carrier aggregation, among which intra-band carrier aggregation can be divided into intra-band continuous carrier aggregation and intra-band non-continuous carrier aggregation.

[0041] Among them, intra-band continuous carrier aggregation means that the component carriers participating in carrier aggregation are continuously distributed in the frequency domain within the same frequency band. Intra-band non-continuous carrier aggregation means that the component carriers participating in carrier aggregation are non-continuously distributed in the frequency domain within the same frequency band. Inter-band carrier aggregation means that the component carriers participating in carrier aggregation are distributed in the frequency domain of different frequency bands.

[0042] Figure 1 A schematic diagram of two-carrier aggregation provided in an embodiment of the present application. Taking two-carrier aggregation as an example, schematic diagrams of intra-band continuous CA, intra-band non-continuous CA and inter-band CA can be referenced. Figure 1 As shown, for intra-band continuous CA, component carrier CC1 and component carrier CC2 are both located in frequency band A and are continuous. For intra-band non-contiguous carrier aggregation, component carrier CC1 and component carrier CC2 are both located in frequency band A, but are not continuous. For inter-band carrier aggregation, component carrier CC1 is located in frequency band A, and component carrier CC2 is located in frequency band B, and the two are in different frequency bands.

[0043] When 5G terminals currently support carrier aggregation, there are differences in the ability to support carrier aggregation. For some low-cost 5G terminals, they are usually limited to supporting only some carrier aggregation, such as supporting up to 3 carrier aggregation. If the current network has 5 carriers, the base station needs to select which 3 carriers to load based on the carrier aggregation capability reported by the terminal. The selection of 3 carriers will affect the terminal air interface rate. For example, if the base station selects 3 small bandwidth carriers or selects a carrier with low MIMO capability, the terminal air interface rate will also be low.

[0044] Based on this, the present application provides a base station multi-carrier selection method, for each basic carrier aggregation combination supported by the terminal and capable of accessing the cell, the performance value of the basic carrier aggregation combination can be determined according to the performance information of multiple carriers contained in the basic carrier aggregation combination. When the performance value of the basic carrier aggregation combination is higher, it means that the air interface rate of the terminal loading the basic carrier aggregation combination is higher, so the basic carrier aggregation combination with the largest performance value can be used as the target carrier aggregation combination, so as to configure the target carrier aggregation combination to the terminal, so as to ensure that the air interface rate of the terminal is higher, which is conducive to improving the communication rate.

[0045] Figure 2 A schematic diagram of a scenario of communication between a base station and a terminal provided in an embodiment of the present application, such as Figure 2 As shown, based on carrier aggregation, the terminal can communicate based on at least two component carriers among component carrier CC1, component carrier CC2, and component carrier CCn configured by the base station, which is beneficial to improving communication efficiency and reducing delay.

[0046] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0047] Figure 3 This is a flow chart of a base station multi-carrier selection method provided in an embodiment of the present application. The method of this embodiment can be executed by a base station. Figure 3 As shown, the method may include:

[0048] S301: Receive carrier aggregation support capability reported by a terminal, where the carrier aggregation support capability includes multiple carrier aggregation combinations supported by the terminal and performance information of each carrier included in the carrier aggregation combination.

[0049] The carrier aggregation support capability reported by the terminal includes all carrier aggregation combinations supported by the terminal. The carrier aggregation combination supported by the terminal may be one or more, each carrier aggregation combination includes at least two carriers, and the carriers included in each carrier aggregation combination are the component carriers shown above.

[0050] In one implementation scenario, for a SA (Standalone) network, the carrier aggregation combination may include NR (New Radio) frequency bands, such as N1+N78.

[0051] In another implementation scenario, for an NSA (Non Standalone) network, the carrier aggregation combination may include NR+LTE (Long Term Evolution) frequency bands, such as B1+B3+N78.

[0052] In some embodiments, the performance information of each carrier included in the carrier aggregation combination is a performance parameter that affects the terminal air interface rate. The performance information of the carrier includes but is not limited to: the bandwidth capability of the carrier, MIMO (Multiple-Input Multiple-Output) capability, and QAM (Quadrature Amplitude Modulation) capability, etc.

[0053] S302: Screen multiple carrier aggregation combinations based on the multi-carrier range configured in the current cell to determine a basic carrier aggregation combination that the terminal can access to the cell.

[0054] In some embodiments, multiple carrier aggregation combinations reported by the terminal may be screened according to the maximum carrier aggregation combination configured in the current cell and the backward compatible carrier aggregation combination to determine a basic carrier aggregation combination that can access the cell among the multiple carrier aggregation combinations. The number of basic carrier aggregation combinations may be one or more.

[0055] S303: Determine the performance value of each basic carrier aggregation combination according to the performance information of the carriers included in the basic carrier aggregation combination, take the basic carrier aggregation combination with the largest performance value as the target carrier aggregation combination, and configure the target carrier aggregation combination to the terminal.

[0056] In some embodiments, each basic carrier aggregation combination includes at least two carriers. For different basic carrier aggregation combinations, the carriers included therein are different to a certain extent, and the performance information of different carriers is also different, so the performance values ​​of different basic carrier aggregation combinations are also different.

[0057] Since the performance information of each carrier is a performance parameter that affects the air interface rate of the terminal, the performance value of the basic carrier aggregation combination obtained based on the performance information of the carrier can be used to characterize the corresponding air interface rate when the terminal loads the basic carrier aggregation combination. When the performance value of the basic carrier aggregation combination is larger, the air interface rate corresponding to the terminal loading the basic carrier aggregation combination is higher.

[0058] In another implementation scenario, if the number of basic carrier aggregation combinations that the terminal can access to the cell is one, that is, the terminal can only communicate through this basic carrier aggregation combination, then there is no need to determine the performance value of the basic carrier aggregation combination, and the basic carrier aggregation combination can be directly used as the target carrier aggregation combination.

[0059] An embodiment of the present application provides a base station multi-carrier selection method, which receives the carrier aggregation support capability reported by the terminal, and the carrier aggregation support capability includes multiple carrier aggregation combinations supported by the terminal and the performance information of each carrier included in the carrier aggregation combination. Multiple carrier aggregation combinations are screened based on the multi-carrier range configured in the current cell, and a basic carrier aggregation combination that the terminal can access to the cell is determined. According to the performance information of the carriers included in the basic carrier aggregation combination, the performance value of each basic carrier aggregation combination is determined, the basic carrier aggregation combination with the largest performance value is used as the target carrier aggregation combination, and the target carrier aggregation combination is configured to the terminal so that the terminal loads the target carrier aggregation combination. The present application determines the performance value of each basic carrier aggregation combination that the terminal supports and can access the cell, and uses the basic carrier aggregation combination with the largest performance value as the target value carrier aggregation combination to configure the terminal, thereby effectively ensuring that the air interface rate of the terminal is in the optimal state and improving the communication rate.

[0060] Figure 4 A flow chart of a method for determining a basic carrier aggregation combination performance value provided in an embodiment of the present application. In one or more embodiments of the present application, each carrier aggregation combination includes at least two carriers, and the performance information of the carriers includes a maximum bandwidth capability value, a maximum multiple-input multiple-output capability value, and an orthogonal amplitude value of each carrier; according to the performance information of the carriers included in the basic carrier aggregation combination, the performance value of each basic carrier aggregation combination is determined, including: Figure 4 Steps shown:

[0061] S401: For each basic carrier aggregation combination, determine a performance value of the carrier based on a maximum bandwidth capability value, a maximum MIMO capability value, and an orthogonal amplitude value of each carrier included in the basic carrier aggregation combination.

[0062] In some embodiments, the maximum bandwidth capability value, the maximum MIMO capability value and the orthogonal amplitude value of the carrier are multiplied, and the obtained product result is used as the performance value of the carrier. A calculation method of the performance value of the carrier can be referred to as follows:

[0063] PerFormance_Carrier(n) = maximum bandwidth capability value * maximum multiple-input multiple-output capability value * orthogonal amplitude value;

[0064] PerFormance_Carrier(n) indicates the performance value corresponding to the nth carrier.

[0065] Typically, the maximum bandwidth capability of a carrier is in the range of (400-1), the maximum MIMO capability is in the range of (8, 4, 2), and the quadrature amplitude is in the range of (8, 6, 4, 2, 1).

[0066] In another implementation scenario, if in addition to the maximum bandwidth capability value, the maximum multiple-input and multiple-output capability value and the orthogonal amplitude value, there are other performance parameters that affect the terminal air interface rate, the other performance parameters can also refer to the calculation method of the above-mentioned carrier performance value to participate in the calculation.

[0067] S402: Determine a performance value of a basic carrier aggregation combination according to the performance value of each carrier.

[0068] In some embodiments, the performance values ​​of multiple carriers included in the basic carrier aggregation combination are summed, and the sum result is used as the performance value of the basic carrier aggregation combination. A method for calculating the performance value of a basic carrier aggregation combination can be referred to as follows:

[0069] PerFormance_SUM=PerFormance_Carrier(1)+PerFormance_Carrier(2)+……+PerFormance_Carrier(n);

[0070] Among them, PerFormance_SUM represents the performance value of the basic carrier aggregation combination, PerFormance_Carrier(n) represents the performance value of a carrier in the carrier aggregation combination, and n is the number of carriers included in the basic carrier aggregation combination.

[0071] For example, for a basic carrier aggregation combination of N1+N78, the performance value of the basic carrier aggregation combination = the performance value of the N1 carrier + the performance value of the N78 carrier.

[0072] After determining the performance values ​​of all basic carrier aggregation combinations, the basic carrier aggregation combination with the highest performance value can be used as the target carrier aggregation combination, and the target carrier aggregation combination can be configured to the terminal so that the terminal loads the frequency band of the target carrier aggregation combination to ensure the optimal terminal air interface rate.

[0073] In summary, for each basic carrier aggregation combination, the performance value of the carrier is determined according to the maximum bandwidth capability, maximum multiple-input and multiple-output capability value, and orthogonal amplitude value of each carrier, and the performance value of the basic carrier aggregation combination in which the carrier is located is further determined according to the performance value of the carrier. Therefore, the target carrier aggregation combination with the best performance can be determined from multiple basic carrier aggregation combinations according to the performance value, which is conducive to ensuring a high air interface rate of the carrier and improving the communication rate.

[0074] It should be noted that the present application only exemplarily illustrates the above-mentioned method for determining the performance value of the basic carrier aggregation combination, which can also be determined by other methods, and the present application does not limit this.
