Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, electronic device and storage medium for screening wireless access capabilities. Background Art

[0002] In the communication protocol of the fifth generation mobile communication technology (5G), the wireless access (FeatureSet) capability in the terminal (UE) capability is the capability range that the UE can support in the corresponding new radio (NR) frequency band, where each frequency band corresponds to a set of FeatureSet capabilities, that is, each NR frequency band corresponds to a FeatureSet capability combination, and each FeatureSet capability in each FeatureSet capability combination corresponds to each carrier on the frequency band.

[0003] In the related technology, FeatureSet capabilities include uplink wireless access capabilities (FeatureSetUplink) and downlink wireless access capabilities (FeatureSetDownlink). The uplink service is FeatureSetUplink, and the downlink service is FeatureSetDownlink. At the same time, the terminal reports multiple sets of FeatureSetUplink capabilities or FeatureSetDownlink capabilities in an array form; in the related technology, for each carrier on each NR frequency band, the reported FeatureSet combination is not necessarily the optimal combination under the conditions of the current base station and terminal support capabilities. The reported FeatureSet capability combination also includes FeatureSet capabilities that are not supported by the base station. For example: a FeatureSet capability combination reported by the terminal includes multiple FeatureSet capabilities, among which some FeatureSet capabilities can be selected by each carrier, and another part of the FeatureSet capabilities cannot be selected by each carrier. The capabilities that cannot be selected by each carrier are FeatureSet capabilities that are not supported by the base station.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The following will describe the application of the method for screening wireless access capabilities and the base station in the embodiment of the present application in conjunction with the accompanying drawings in the embodiment of the present application.

[0033] Figure 1 A flow chart of a method for screening wireless access capabilities of a base station provided in an embodiment of the present application. Figure 1 As shown, the wireless access capability screening method provided in the embodiment of the present application includes the following steps:

[0034] Step S101: Acquire multiple first wireless access capabilities for carrier selection reported by a terminal, wherein the wireless access capability includes at least one first sub-capability, each first sub-capability has a corresponding first preset capability value, and the first sub-capability is an incompatible sub-capability.

[0035] In this embodiment, before the base station performs the radio access capability screening, the base station will first send a radio resource control signaling RRC (Radio Resource Control, RRC), for example: signaling UECapabilityEnquiry, to request the terminal (ie, UE) for the UE's radio access capability (ie, UE capability). Specifically, according to the 3gpp protocol, the specified working frequency band of the UE will be specified in the information element capabilityRequestFilter in the signaling UECapabilityEnquiry, and the UE will report the corresponding UE capability through RRC according to the specified working frequency band.

[0036] After the UE reports the UE capability, in the base station architecture with CU (Centralized Unit) and DU (Distributed Unit) separated, the base station processes the RRC information in the CU part, extracts the UE capability, and sends the UE capability to the MAC layer of the DU part, and the DU part performs MAC (Media Access Control) layer scheduling according to the UE capability. Before the MAC layer scheduling is performed, the UE capability screening process will be entered first.

[0037] In this embodiment, in this embodiment, all first sub-capabilities of the wireless access capability reported by the UE have corresponding first preset capability values. When further explanation is required, all sub-capabilities of the wireless access capability reported by the UE have corresponding preset capability values; the method of the embodiment of the present application is executed by a base station, and the screening of the wireless access capability sent by the terminal is performed, and the above screening is performed based on the comparison between the first preset capability value of the wireless access capability and the capability support interval of the base station for the first sub-capability, wherein the wireless access capability includes the following transmission-related sub-capabilities: subcarrier spacing, frequency range, maximum bandwidth, maximum modulation order corresponding to the modulation mode, and maximum number of MIMO layers. At the same time, the wireless access capability involved in the embodiment of the present application also includes sub-capabilities such as the maximum number of uplink sounding reference signals and support for special time slots, and the subcarrier spacing, frequency range, maximum bandwidth, maximum modulation order corresponding to the modulation mode, and maximum number of MIMO layers are sub-capabilities in the wireless access capability that directly affect the data transmission rate during data transmission.

[0038] Specifically, the frequency range refers to the range in which the frequency band is divided. For the 5G NR frequency band, the divided frequency range includes two frequency ranges, one of which corresponds to a frequency band below 6 GHZ, and the other corresponds to a frequency band of 24.25 GHz-52.6 GHz; the maximum bandwidth is the maximum bandwidth used for each carrier communication within the corresponding frequency range. In the present application and related technologies, the above-mentioned sub-capabilities include incompatible sub-capabilities and compatible sub-capabilities for the base station, wherein the incompatible sub-capability is the first sub-capability, and the incompatible sub-capability means that there is a mutually exclusive relationship between the values ​​of the corresponding capability values, that is, when the base station and the terminal have different values ​​in the sub-capability, , the wireless access capability corresponding to the sub-capability is not supported by the base station; compatible sub-capabilities refer to the existence of a downward compatible relationship between the values ​​of the corresponding capability values, and the sub-capability with a larger value supports the sub-capability with a smaller value. The base station and the terminal may have different or same values ​​for the same sub-wireless access capability. When the values ​​are different, the base station may use the sub-capability with a smaller value among the sub-capabilities corresponding to the base station and the terminal to schedule the transmission of the UE; in this embodiment, the subcarrier spacing and frequency range are incompatible first sub-capabilities, while the maximum bandwidth, the maximum modulation order corresponding to the modulation method, and the maximum number of MIMO layers are compatible second sub-capabilities.

[0039] In this embodiment, among the sub-capabilities of the wireless access capability, the incompatible sub-capabilities, that is, the first sub-capabilities, can be directly confirmed by the type or attribute of the sub-capabilities. For example, when a sub-capability is determined to be a subcarrier spacing, the sub-capability can be directly determined to be an incompatible sub-capability. In some optional embodiments, the wireless access capability includes two first sub-capabilities, and the two first sub-capabilities are the subcarrier spacing and the frequency range. It can be understood that the case in which the number of first sub-capabilities listed in this embodiment is 2 (for example, subcarrier spacing, frequency range) is only an example, and the present disclosure is not limited to the specific number and the specific first sub-capability type.

[0040] Step S102: Obtain a capability support range of each first sub-capability of the base station.

[0041] In this embodiment, the capability support interval is a capability range supported by the base station for the corresponding first sub-capability.

[0042] Step S103: determine whether the first preset capability value corresponding to each first sub-capability in the wireless access capability is within the corresponding capability support interval; if so, determine the corresponding wireless access capability as a candidate wireless access capability.

[0043] In this embodiment, by judging whether the capability support interval of the base station for each first sub-capability, that is, whether the capability range matches the first preset capability value of the first sub-capability in the wireless access capability reported by the UE, it is determined whether the corresponding first sub-capability is a sub-capability supported by the base station. For example, if the first sub-capability is a subcarrier spacing and a frequency range, the base station's capability support interval set for the subcarrier spacing is {2, 3, 4}, and the support interval set for the frequency range is [min, max], where min is the minimum value of the frequency range, and the value range is 20GHz-25GHz, and max is the maximum value of the frequency range, and the value range is 50GHz-54GHz. The subcarrier spacing in the wireless access capability reported by the UE is 3ms, and the frequency range is [24.25GHz, 52.6GHz], indicating that the wireless access capability with the subcarrier spacing and frequency range is the wireless access capability supported by the base station.

[0044] In this embodiment, when all sub-capabilities of the radio access capability reported by the UE include a first sub-capability that meets the set requirement, it is determined that the radio access capability is a capability supported by the base station, that is, a radio access capability that can be used for transmission scheduling.

[0045] In this embodiment, by obtaining the capability support interval that the base station can support in the two first sub-capabilities of subcarrier spacing and frequency range, the capability support interval corresponding to the first sub-capability is compared with the first preset capability value of the first sub-capability, thereby screening the wireless access capability reported by the UE, obtaining all candidate wireless access capabilities supported by the base station, and adding them to the candidate wireless access capability array.

[0046] In this embodiment, by comparing the first preset capability value of the first sub-capability with the capability support interval (supported by the base station itself), it is determined whether the selected first sub-capability is a sub-capability supported by the base station; at the same time, when each first sub-capability is determined to be a sub-capability supported by the base station, it indicates that the first wireless access capability can be used as a candidate wireless access capability, and MAC layer transmission scheduling can be directly performed based on the candidate wireless access capability, or the candidate wireless access capabilities can be further screened (for example, based on the maximum peak rate), and MAC layer transmission scheduling is performed through the wireless access capabilities obtained by the further screening.

[0047] In this embodiment, the wireless access capability can be represented by a wireless access capability identifier (ID). By setting a corresponding ID for each wireless access capability in the wireless access capability array based on the protocol rules formulated in the 3gpp protocol, the corresponding wireless access capability is replaced by the ID in the corresponding screening process, thereby completing the corresponding screening, which can reduce memory consumption. For example: when the wireless access capability array F = {ID1, ID2, ..., IDi}, determine whether all the wireless access capabilities in the wireless access capability array reported by the UE are candidate wireless access capabilities supported by the base station. If they are candidate wireless access capabilities supported by the base station, add the ID of the wireless access capability to the candidate wireless access capability array; otherwise, do not add it.

[0048] Step S104: performing transmission scheduling based on the first candidate wireless access capability.

[0049] In this embodiment, after the candidate wireless access capabilities are obtained, the transmission scheduling of the MAC layer can be directly performed based on the candidate wireless access capabilities, or the candidate wireless access capabilities can be further screened and the transmission scheduling of the MAC layer can be performed based on the wireless access capabilities obtained by the further screening.

[0050] Through the above steps S101 to S104, the problem in the related art that the wireless access capabilities are not effectively screened, resulting in the termination of carrier transmission and affecting the base station scheduling is solved, and the wireless access capabilities supported by the base station are screened out based on the compatibility of the sub-capabilities in the wireless access capabilities, thereby improving the scheduling efficiency of the base station.

[0051] In some optional embodiments, the wireless access capability includes two of the first sub-capabilities, and the two of the first sub-capabilities are respectively a subcarrier spacing and a frequency range.

[0052] Figure 2 Schematic diagram of the process of the method for screening the wireless access capability of the base station provided in the preferred embodiment of the present application Figure 1 .like Figure 2 As shown, in some embodiments, the wireless access capability includes two first sub-capabilities, the two first sub-capabilities are respectively a subcarrier spacing and a frequency range, and the following optional steps are implemented:

[0053] Step S201: determine whether first preset capability values ​​corresponding to two first sub-capabilities in the wireless access capability are both within the corresponding capability support range.

[0054] Step S202: When it is determined that the first preset capability values ​​corresponding to the two first sub-capabilities are both within the corresponding capability support interval, the corresponding wireless access capability is determined as a candidate wireless access capability.

[0055] Through steps S201 to S202, the first wireless access capability is screened based on multiple first sub-capabilities to see whether it is a wireless access capability supported by the base station. By setting the screening condition to satisfy that multiple incompatible first sub-capabilities are all sub-capabilities supported by the base station, the accuracy of the screened wireless access capabilities is improved and the scheduling efficiency of the base station is improved.

[0056] Figure 3 Schematic diagram of the process of the method for screening the wireless access capability of the base station provided in the preferred embodiment of the present application Figure 2 . refer to Figure 3 In some embodiments, the wireless access capability further includes a plurality of second sub-capabilities, and transmission scheduling is performed based on the candidate wireless access capability, which can be implemented by the following steps:

[0057] Step S301: Acquire a second sub-capability corresponding to a candidate wireless access capability, wherein the second sub-capability is a sub-capability that is backward compatible, and each second sub-capability has a corresponding second preset capability value.

[0058] In this embodiment, the plurality of second sub-capabilities are respectively the maximum bandwidth, the maximum modulation order corresponding to the modulation mode, and the maximum number of MIMO layers.

[0059] Step S302: Obtain the capability support value of the base station for each second sub-capability.

[0060] In this embodiment, because the second sub-capability is a backward compatible sub-capability, the sub-capability with a larger capability value supports the sub-capability with a smaller capability value. When the capability support value of the base station for the second sub-capability is different from the second preset capability value of the terminal for the same second sub-capability, the base station can use the second sub-capability with a smaller capability value in the sub-capabilities corresponding to the base station and the terminal to schedule the UE's transmission.

[0061] Step S303: Calculate the supported peak rate based on the first preset capability value, the second preset capability value and the capability support value corresponding to each candidate wireless access capability to obtain multiple peak rates.

[0062] In this embodiment, the means used to calculate the peak rate supported by the base station include but are not limited to the existing calculation formula for calculating the maximum data rate.

[0063] In this embodiment, after the candidate wireless access capabilities are screened out, the wireless access capabilities with the highest data rate are screened out based on the capability values ​​of all sub-capabilities of the screened wireless access capabilities, that is, the data rate is calculated based on the capability values ​​corresponding to the first sub-capability and the second sub-capability of the screened wireless access capabilities, and the wireless access capabilities used for transmission scheduling at the MAC layer are screened out based on the calculated data rate.

[0064] In this embodiment, the capability value of the second sub-capability is determined based on the second preset capability value corresponding to the second sub-capability reported by the UE and the capability support value supported by the base station itself. Specifically, the smaller capability value of the two is selected as the capability value corresponding to the second sub-capability, so as to meet the compatibility of the base station and the UE.

[0065] In this embodiment, a wireless access capability reported by the UE can calculate a peak rate. At the same time, the wireless access capability for calculating the peak rate is a wireless access capability that satisfies the first preset capability value of each first sub-capability and satisfies the capability support interval corresponding to the base station; in this embodiment, the calculation of the peak rate can also be completed based on the corresponding ID.

[0066] Step S304: determine a peak rate among the multiple peak rates that is not less than a preset first threshold as a target rate, and determine a candidate wireless access capability corresponding to the target rate as a target wireless access capability.

[0067] In this embodiment, the wireless access capability for peak rate screening is a candidate wireless access capability that has completed screening based on the capability value of the first sub-capability satisfying the capability support interval corresponding to the base station, and screening based on the peak rate satisfying the preset condition is completed among the candidate wireless access capabilities, so as to select the target wireless access capability from the candidate wireless access capabilities, wherein the preset condition is set as the rate value of the peak rate is not less than a preset first threshold value, and in some optional implementation methods, the first threshold value is the maximum peak rate among multiple peak rates.

[0068] Step S305: Perform transmission scheduling according to the target wireless access capability.

[0069] In this embodiment, after the target wireless access capability is screened out, the capability values ​​of all sub-capabilities of the target wireless access capability are used as the maximum wireless access capability reported by the UE to participate in the scheduling of the MAC layer of the base station, that is, the first preset capability value corresponding to the first sub-capability of the target wireless access capability and the target capability value corresponding to the second sub-capability are used as the maximum wireless access capability reported by the UE to participate in the transmission scheduling of the MAC layer.

[0070] Through the above steps S301 to S305, the problem that the wireless access capability is not effectively screened in the related technology, resulting in the termination of carrier transmission and affecting the base station scheduling is further solved, and the wireless access capability with the largest data rate is screened out based on the compatibility of the sub-capabilities in the wireless access capability and the relationship with the data transmission rate, thereby improving the scheduling efficiency of the base station.

[0071] It should be noted that in some of the optional implementations, before performing the peak rate calculation, it is also possible to set restriction conditions for one or more sub-capabilities according to the application scenario requirements, so that the screened wireless access capabilities meet the MAC layer scheduling of the base station in the corresponding application scenario, thereby improving the efficiency of the base station's MAC layer scheduling.

[0072] Figure 4 Schematic diagram of the process of the method for screening the wireless access capability of the base station provided in the preferred embodiment of the present application Figure 3 .like Figure 4 As shown, in some embodiments, based on the first preset capability value, the second preset capability value and the capability support value corresponding to each candidate wireless access capability, the supported peak rate is calculated to obtain multiple peak rates, and the following steps may also be included:

[0073] Step S401 : Select the minimum capability value from the second preset capability value and the capability support value corresponding to each second sub-capability to obtain the target capability value corresponding to each second sub-capability.

[0074] In this embodiment, when the three second sub-capabilities of the maximum bandwidth, the modulation order of the maximum modulation mode, and the maximum number of MIMO layers in the wireless access capability reported by the UE participate in the peak rate calculation, they need to be compared with the capability support values ​​of the three second sub-capabilities that the base station can support, and the smaller capability value of the two is used to participate in the peak rate calculation; at the same time, the three sub-capabilities of the maximum bandwidth, the modulation order of the maximum modulation mode, and the maximum number of MIMO layers meet backward compatibility. Therefore, if the maximum wireless access capability that the base station can support is higher, the transmission scheduling of the UE can be performed according to the corresponding wireless access capability reported by the UE; if the maximum wireless access capability that the base station can support is lower, then the capability values ​​of the sub-capabilities participating in the calculation of the peak rate are limited by the maximum capability values ​​of the sub-capabilities supported by the base station itself.

[0075] Step S402: Calculate the supported peak rate according to the first preset capability value and the target capability value corresponding to each candidate wireless access capability to obtain multiple peak rates.

[0076] In this embodiment, the three target capability values ​​of maximum bandwidth, maximum modulation order of modulation mode and maximum number of MIMO layers can be backward compatible sub-capability values, and the first preset capability value is the subcarrier spacing and frequency range, which are not backward compatible sub-capability values. At the same time, when calculating the peak rate, because the first preset capability value is the capability value that has been verified and supported by the base station, the original value of the corresponding capability value reported by the UE is used.

[0077] Through the above steps S401 to S402, the radio access capability that enables the base station to perform MAC layer scheduling with the maximum radio access capability is selected from the radio access capabilities supported by the base station and the radio access capabilities reported by the UE, thereby improving the MAC layer scheduling efficiency of the base station.

[0078] In some embodiments, the candidate wireless access capability includes two first sub-capabilities and multiple second sub-capabilities, the two first sub-capabilities are respectively a subcarrier spacing and a frequency range, and the multiple sub-capabilities are respectively a maximum bandwidth, a maximum modulation order corresponding to a modulation mode, and a maximum number of MIMO layers. After respectively obtaining the first preset capability values ​​corresponding to all the first sub-capabilities and the target capability values ​​corresponding to all the second sub-capabilities corresponding to each candidate wireless access capability, the peak value is calculated according to the following formula:

[0079]

[0080] in,

[0081] data rate (Mbps) is the peak rate;

[0082] J is the number of carriers aggregated within or between bands of the base station;

[0083] is the target capacity value corresponding to the maximum number of MIMO layers, where the larger the parameter value is, the larger the corresponding peak rate is;

[0084] The target capability value corresponding to the maximum modulation order of the modulation mode is the modulation order. The larger the value, the higher the corresponding peak rate.

[0085] f (j) is the scaling factor, which controls the peak rate and takes values ​​of 0.4, 0.75, 0.8 or 1;

[0086] R max Maximum target bit rate, the value is 948 / 1024;

[0087] μ is a first preset capability value corresponding to the subcarrier spacing;

[0088] is the average duration of an OFDM subframe with a subcarrier spacing of μ;

[0089] BW(j) is the target capacity value corresponding to the maximum bandwidth;

[0090] The maximum resource block RB allocated when the first preset capability value corresponding to the subcarrier spacing is μ and the target capability value corresponding to the maximum bandwidth is BW(j),

[0091] The maximum number of resource blocks per second corresponding to the maximum bandwidth and subcarrier spacing. The larger the parameter value, the higher the peak rate. When the subcarrier spacing is the same, the larger the maximum bandwidth, the larger the maximum number of resource blocks per second. When the maximum bandwidth is the same, the smaller the subcarrier spacing, the larger the maximum number of resource blocks per second.

[0092] OH (j) The smaller the value of this parameter is, the higher the peak rate is.

[0093] In this embodiment, according to the above-mentioned peak rate calculation formula, the capability values ​​of the five sub-capabilities of a wireless access capability have the following relationship with the peak rate: the peak rate is directly proportional to the capability value modulation order corresponding to the number of MIMO layers, the maximum bandwidth, and the maximum modulation mode, and is inversely proportional to the capability value corresponding to the subcarrier spacing and the frequency range.

[0094] Through the above steps, the screening of the wireless access capability with the maximum data rate is achieved.

[0095] Figure 5 Schematic diagram of the process of the method for screening the wireless access capability of the base station provided in the preferred embodiment of the present application Figure 4 ,like Figure 5 As shown, in some of the embodiments, after transmission scheduling is performed according to the target wireless access capability, the following steps are further implemented:

[0096] Step S501: Calculate the corresponding theoretical rate according to the first preset capability value and the second preset capability value corresponding to each current candidate wireless access capability to obtain multiple theoretical rates.

[0097] In this embodiment, for each candidate wireless access capability, multiple theoretical rates are calculated using the first preset capability value corresponding to the two first sub-capabilities of subcarrier spacing and frequency range and the second preset capability value corresponding to the three second sub-capabilities of maximum bandwidth reported by the UE, modulation order of the maximum modulation method, and number of MIMO layers, and each wireless access capability corresponds to a theoretical rate.

[0098] Step S502, determining the theoretical rate with the largest difference from the target rate among multiple theoretical rates as the alternative rate, and determining the candidate wireless access capability corresponding to the alternative rate as the alternative wireless access capability, and when the peak rate corresponding to the alternative wireless access capability reaches the alternative rate, confirming the alternative wireless access capability as the target wireless access capability.

[0099] In this embodiment, the difference between the theoretical rate (corresponding to the ideal peak rate calculated based on the capability values ​​of all sub-capabilities of the radio access capability reported by the UE) and the target rate (corresponding to the actual peak rate calculated based on the capability values ​​of all sub-capabilities of the radio access capability currently supported by the base station) is calculated, so as to compare the difference between the ideal peak rate and the actual peak rate, wherein the larger the difference is, the higher the capability upper limit of the radio access capability reported by the UE is, the theoretical rate with the largest difference is selected as the candidate rate, and the candidate radio access capability corresponding to the candidate rate is called the candidate radio access capability, when the configuration of the capability support value supported by the base station for each sub-capability is changed, for example, the corresponding capability support value is increased, so that the peak rate corresponding to the candidate radio access capability is improved, especially when the capability support intervals of the two first sub-capabilities of subcarrier spacing and frequency range remain unchanged, and the capability support values ​​of the three second sub-capabilities of maximum bandwidth, modulation order and number of MIMO layers all reach the corresponding second preset capability values ​​in the radio access capability reported by the UE, at this time, the candidate radio access capability is confirmed as the target radio access capability, thereby saving time.

[0100] In some of the optional implementations, a capability scoring screening mechanism may be added, and the corresponding scoring mechanism is that the larger the difference, the higher the score. In this way, time is saved by selecting a peak rate with a high score as the target rate, and using the candidate wireless access capability corresponding to the target rate as the target wireless access capability selected by the base station.

[0101] Through the above steps S501 to S502, the calculation of the peak rate is advanced. When the wireless access capability supported by the base station is improved, the corresponding wireless access capability can be determined without recalculation, thus saving time.

[0102] The following is a description of the relevant technologies when the method of the embodiment of the present application is applied to a terminal.

[0103] The content of wireless access capability is relatively large. If the terminal can only report the wireless access capability supported by the base station in the wireless access capability array, the length of the RRC signaling can be reduced. At this time, the base station RRC request signaling needs to be extended; for the signaling extension of the base station RRC request: the base station requests UE capability from the terminal by sending the RRC signaling UECapabilityEnquiry. According to the 3gpp protocol, the RAT type and working frequency band of the UE capability will be specified in the cell capabilityRequestFilter in the signaling UECapabilityEnquiry. The terminal will report the corresponding UE capability according to the specified content; to realize the terminal side's screening of the wireless access capability to be reported, both the terminal and the base station need to add non-protocol extensions to the interaction of the RRC signaling UECapabilityEnquiry. The base station puts the supported subcarrier spacing, frequency range and other information into the cell capabilityRequestFilter. When the terminal reads the cell capabilityRequestFilter, it obtains the supported subcarrier spacing, frequency range and other information from the base station.

[0104] The following will describe the application and terminal of the method for screening wireless access capabilities in the embodiment of the present application in conjunction with the accompanying drawings in the embodiment of the present application.

[0105] Figure 6 A flow chart of a method for screening wireless access capabilities of a terminal provided in an embodiment of the present application. Figure 6 As shown, the wireless access capability screening method provided in the embodiment of the present application includes the following steps:

[0106] Step S601: obtaining a capability support interval of each first sub-capability of a radio access capability to be reported by a base station, wherein the radio access capability includes at least one first sub-capability, and the first sub-capability is an incompatible sub-capability.

[0107] In this embodiment, the capability support interval of each first sub-capability of the wireless access capability to be reported by the base station obtained by the UE is obtained by obtaining the RRC request signaling information sent by the base station, wherein the information element UE-CapabilityRequestFilterNR in the RRC request signaling information (such as: UECapabilityEnquiry) will specify the corresponding working frequency band to the UE, so that the UE can report the UE capability of the corresponding working frequency band; in the information element UE-CapabilityRequestFilterNR, a new information element can be added to indicate the capability values ​​of sub-capabilities such as subcarrier spacing and frequency range that the base station can support; when the base station sends the RRC signaling UECapabilityEnquiry, the wireless access capability supported by the base station is added to the new information element, and when the terminal receives the RRC signaling UECapabilityEnquiry, it must read the information in the new information element to obtain the capability value of the sub-capability corresponding to the wireless access capability that the base station can support.

[0108] In this embodiment, the content of the wireless access capability is relatively large. If the UE can report only the wireless access capability supported by the base station in the wireless access capability array, the length of the RRC signaling can be reduced. At this time, the base station RRC request signaling needs to be extended; for the signaling extension of the base station RRC request: the base station requests the UE capability by sending the RRC signaling UECapabilityEnquiry. According to the 3gpp protocol, the UE's designated working frequency band will be specified in the cell capabilityRequestFilter in the signaling UECapabilityEnquiry, and the UE will report the corresponding UE capability through RRC according to the designated working frequency band; to realize the UE side's screening of the wireless access capability to be reported, both the UE and the base station need to add an extension outside the protocol to the interaction of the RRC signaling UECapabilityEnquiry. The base station puts the capability values ​​corresponding to the supported subcarrier spacing and frequency range into the cell capabilityRequestFilter, and the UE obtains the capability values ​​of the corresponding sub-capabilities supported by the base station when reading the cell capabilityRequestFilter.

[0109] In this embodiment, the method of the embodiment of the present application is performed by the UE, and the screening of the wireless access capability to be reported is performed, and the screening is performed based on the comparison of the capability values ​​of multiple sub-capabilities of the wireless access capability.

[0110] In this embodiment, the wireless access capability to be reported includes at least one first sub-capability and multiple second sub-capabilities, each first sub-capability has a corresponding capability support interval, the first sub-capability is a sub-capability that is not backward compatible, the second sub-capability has a corresponding second preset capability value, and the second sub-capability is a sub-capability that is backward compatible; wherein, the wireless access capability to be reported includes the following sub-capabilities: subcarrier spacing, frequency range, maximum bandwidth, maximum modulation order corresponding to the modulation mode, and maximum number of MIMO layers; in this embodiment, the wireless access capability has two incompatible first sub-capabilities of subcarrier spacing and frequency range, and the maximum bandwidth, maximum modulation order corresponding to the modulation mode, and maximum number of MIMO layers are the corresponding second sub-capabilities.

[0111] Step S602: Acquire a first preset capability value configured by the terminal for each first sub-capability from a plurality of radio access capabilities to be reported.

[0112] In this embodiment, the corresponding wireless access capability is screened according to the first preset capability value of the corresponding first sub-capability.

[0113] Step S603: determine whether the first preset capability value corresponding to each first sub-capability in the wireless access capability is within the corresponding capability support interval; if so, determine the corresponding wireless access capability as a candidate wireless access capability.

[0114] In this embodiment, by judging whether the first preset capability value of the first sub-capability in the wireless access capability to be reported matches the capability support interval of each first sub-capability of the base station, that is, whether the capability range matches, it is determined whether the corresponding first sub-capability satisfies the sub-capability supported by the base station. For example, when the capability support interval of the base station for the subcarrier spacing is 2 to 4 subcarriers, and the subcarrier spacing in the wireless access capability to be reported is 3 subcarriers, it means that the subcarrier spacing is supported by the base station; at the same time, when all the sub-capabilities of the wireless access capability to be reported have the first sub-capability that meets the set requirements, it is determined that the wireless access capability is the wireless access capability to be reported to the base station and is supported by the base station, so that the base station performs transmission scheduling based on the corresponding wireless access capability.

[0115] Step S604: reporting the candidate radio access capabilities so that the base station performs transmission scheduling based on the candidate radio access capabilities.

[0116] In this embodiment, after the candidate wireless access capabilities are obtained, the candidate wireless access capabilities may be directly reported to the base station, or the candidate wireless access capabilities may be further screened and the wireless access capabilities obtained through the further screening may be reported to the base station.

[0117] Through the above steps S601 to S604, the wireless access capabilities reported by the UE are only the wireless access capabilities supported by the base station, which reduces the length of the RRC signaling sent by the UE. At the same time, the problem that the wireless access capabilities selected by the base station cannot complete MAC layer scheduling and cause carrier transmission termination is reduced.

[0118] Figure 7 Schematic diagram of the process of the method for screening the wireless access capability of the terminal provided in the preferred embodiment of the present application Figure 1 .like Figure 7 As shown, in some embodiments, the wireless access capability further includes a plurality of second sub-capabilities, so that the base station performs transmission scheduling based on the candidate wireless access capability, which can be implemented by the following steps:

[0119] Step S701: Acquire multiple second sub-capabilities corresponding to the candidate wireless access capability to be reported, and acquire a second preset capability value configured by the terminal for each second sub-capability, wherein the second sub-capability is a sub-capability that is backward compatible.

[0120] In this embodiment, the wireless access capabilities to be reported and the candidate wireless access capabilities include, in addition to the first sub-capabilities, multiple second sub-capabilities. In this embodiment, the multiple second sub-capabilities are the maximum bandwidth, the maximum modulation order corresponding to the modulation mode, and the maximum number of MIMO layers.

[0121] Step S702: Acquire a capability support value of each second sub-capability of the candidate radio access capability to be reported by the base station.

[0122] In this embodiment, because the second sub-capability is a backward compatible sub-capability, the sub-capability with a larger capability value supports the sub-capability with a smaller capability value. When the capability support value of the base station for the second sub-capability is different from the second preset capability value of the terminal for the same second sub-capability, the base station can use the second sub-capability with a smaller capability value in the sub-capabilities corresponding to the base station and the terminal to schedule the UE's transmission.

[0123] Step S703, based on the first preset capability value, the second preset capability value and the capability support value corresponding to each candidate wireless access capability, calculate the peak rate supported by the base station, and determine the peak rate of the calculated multiple peak rates that is not less than the first threshold as the target rate, and determine the candidate wireless access capability corresponding to the target rate as the target wireless access capability, so that the base station performs transmission scheduling according to the target wireless access capability.

[0124] In this embodiment, the capability value of the second sub-capability is determined based on the corresponding second preset capability value configured for the second sub-capability and the acquired capability support value supported by the base station. Specifically, the smaller capability value of the two is selected as the capability value corresponding to the second sub-capability, so as to meet the compatibility between the base station and the UE.

[0125] In this embodiment, a wireless access capability to be reported can calculate a peak rate. At the same time, a wireless access capability for calculating the peak rate is a wireless access capability that satisfies the first preset capability value of each first sub-capability that satisfies the capability support interval corresponding to the base station.

[0126] In this embodiment, the wireless access capability for peak rate screening is a candidate wireless access capability that has completed screening based on the capability value of the first sub-capability satisfying the capability support interval corresponding to the base station, and screening based on the peak rate satisfying the preset condition is completed among the candidate wireless access capabilities, so as to select the target wireless access capability from the candidate wireless access capabilities, wherein the preset condition is set as the rate value of the peak rate is not less than a preset first threshold value, and in some optional implementation methods, the first threshold value is the maximum peak rate among multiple peak rates.

[0127] In this embodiment, after the candidate wireless access capabilities are screened out, the corresponding rate is calculated by using the corresponding peak rate calculation method on the base station side to complete the corresponding screening; it should be noted that in the embodiment of the present application, the screening of wireless access capabilities on the UE side corresponds to the screening of wireless access capabilities on the base station side, which will not be repeated here.

[0128] Through the above steps S701 to S703, it is further achieved that the wireless access capabilities reported by the UE are only the wireless access capabilities supported by the base station, reducing the length of the RRC signaling sent by the terminal. At the same time, it is avoided that the wireless access capabilities selected by the base station cannot complete the MAC layer scheduling and cause the carrier transmission to be terminated.

[0129] Figure 8 Schematic diagram of the process of the method for screening the wireless access capability of the terminal provided in the preferred embodiment of the present application Figure 2 .like Figure 8 As shown, in some embodiments, the candidate wireless access capability includes two first sub-capabilities and multiple second sub-capabilities, the two first sub-capabilities are respectively a subcarrier spacing and a frequency range, and the multiple sub-capabilities are respectively a maximum bandwidth, a maximum modulation order corresponding to a modulation mode, and a maximum number of MIMO layers. Based on the first preset capability value, the second preset capability value, and the capability support value corresponding to each candidate wireless access capability, the peak rate supported by the base station is calculated, and the following steps may also be included:

[0130] Step S801 : Select the minimum capability value from the second preset capability value and the capability support value corresponding to each second sub-capability to obtain the target capability value corresponding to each second sub-capability.

[0131] In this embodiment, when the three second sub-capabilities of the maximum bandwidth, the modulation order of the maximum modulation mode, and the maximum number of MIMO layers in the wireless access capability to be reported participate in the peak rate calculation, they need to be compared with the capability support values ​​of the three second sub-capabilities that the base station can support, and the smaller capability value of the two is used to participate in the peak rate calculation; at the same time, the three sub-capabilities of the maximum bandwidth, the modulation order of the maximum modulation mode, and the maximum number of MIMO layers meet backward compatibility. Therefore, if the maximum wireless access capability that the base station can support is higher, the transmission scheduling of the UE can be performed according to the corresponding wireless access capability reported by the UE; if the maximum wireless access capability that the base station can support is lower, then the capability values ​​of the sub-capabilities participating in the calculation of the peak rate are limited by the maximum capability values ​​of the sub-capabilities supported by the base station itself.

[0132] Step S802: Calculate the peak rate supported by the base station according to the first preset capability value and the target capability value corresponding to each candidate wireless access capability.

[0133] In this embodiment, the three target capability values ​​of maximum bandwidth, maximum modulation order of modulation mode and maximum number of MIMO layers can be backward compatible sub-capability values, and the first preset capability value is the subcarrier spacing and frequency range, which are not backward compatible sub-capability values. At the same time, when calculating the peak rate, because the first preset capability value is the capability value that has been verified and supported by the base station, the original value of the corresponding capability value reported by the UE is used.

[0134] Through step S801 to step S802, the wireless access capability that enables the base station to perform MAC layer scheduling with the maximum wireless access capability is selected from the wireless access capabilities supported by the base station and the wireless access capabilities to be reported, so that the reported wireless access capability can improve the MAC layer scheduling efficiency of the base station.

[0135] Fig. 9 Schematic diagram of the process of the method for screening the wireless access capability of the terminal provided in the preferred embodiment of the present application Figure 3 .like Fig. 9 As shown, in some embodiments, obtaining the capability support interval of each first sub-capability of the radio access capability to be reported by the base station, and obtaining the capability support value of each second sub-capability of the candidate radio access capability to be reported by the base station can be implemented by the following steps:

[0136] Step S901, obtaining radio control RRC request signaling information sent by a base station, wherein the RRC request signaling carries parameters for characterizing a capability support interval of the base station for each first sub-capability and a capability support value for each second sub-capability;

[0137] Step S902: extracting the capability support interval of the base station for each first sub-capability and the capability support value for each second sub-capability from the RRC request signaling.

[0138] Through step S901 to step S902, the capability support value and / or capability support interval of the sub-capability of the wireless access capability to be reported by the base station is obtained through RRC signaling, so that the wireless access capability reported by the UE is only the wireless access capability supported by the base station, reducing the length of the RRC signaling sent by the terminal, and avoiding the problem that the wireless access capability selected by the base station cannot complete MAC layer scheduling and causes carrier transmission termination.
