In order to facilitate the understanding of the technical solutions of the embodiments of the present application, the related technologies of the embodiments of the present application are described below. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and all of them belong to the embodiments of the present application. protected range.

The carrier aggregation capability refers to the ability of a terminal device to simultaneously transmit and receive data on two or more continuous or non-contiguous cells or carriers. The CA capability may include the CA capability of Multi-RAT Dual Connectivity (MR-DC), or the CA capability of a single RAT. Among them, MR-DC may include Evolved Universal Terrestrial Radio Access New Air Interface Dual Connection (EUTRA NR Dual Connection, EN-DC), New Air Interface Evolved Universal Terrestrial Radio Access Dual Link (NR EUTRA Dual Connection, NE-DC), etc. This embodiment of the present application does not limit this. The CA capability of a single radio access technology may be NR-CA capability or EUTRA-CA capability, which is not limited in this embodiment of the present application. It should be noted that the carrier aggregation capability may also include the CA capability that needs to be reported in the next generation cellular mobile communication system and other mobile communication systems that will be developed subsequently. This embodiment of the present application does not limit it.

In related technologies, referring to the flowchart shown in FIG. 2 , the terminal device may receive a UECapabilityEnquiry message sent by the network device, and the UECapabilityEnquiry message may include that the network device inquires about the frequency band (band) corresponding to the CA capability. The terminal device sends UE capability information (UECapabilityInformation) to the network device based on the order of the bands inquired by the network device and based on the radio frequency hardware support of the terminal device itself and the maximum reported capacity value supported by the terminal device itself. The UECapabilityInformation may include multiple CA combinations. In this way, the network device can configure the serving cell or the measurement gap according to the CA combination included in the UECapabilityInformation.

The bands inquired by the network device may include EUTRA frequency bands and NR frequency bands. For the convenience of introduction, B represents the EUTRA frequency band, and N represents the NR frequency band. For example, band EUTRA 1 is referred to as B1, band EUTRA 3 is referred to as B3, bandNR1 is referred to as N1, and bandNR3 is referred to as N3.

Assume that the frequency bands inquired by the network device in UECapabilityEnquiry are B1, B3, B7, B8, N1, and N3 in sequence. If the radio frequency hardware of the terminal device can support the band inquired by the network device, the terminal device needs to send the CA capability of EN-DC (also called EN-DC capability) and the CA capability of NR (also called NR-DC capability) to the network device. CA capability), which can be the CA combination of EN-DC and the CA combination of NR. However, since there is an upper limit on the maximum reporting capacity value of the capability information sent by the terminal device, generally, the total capacity of the UECapabilityInformation message sent by the terminal device to the network device at one time cannot exceed the maximum reporting capacity value, and the maximum reporting capacity value can be 8 kilobytes (i.e. 8K). Exemplarily, if the network device inquires the EN-DC capability and the NR-CA capability simultaneously in UECapabilityEnquiry, the total data volume of the identification information of the CA combination of EN-DC and the identification information of the CA combination of NR-CA cannot exceed 8K. Therefore, due to capacity limitations, in some cases, some CA combinations cannot be reported normally, resulting in abnormal calls, abnormal SMS messages, and unstable data networks. Moreover, under the condition of limited capacity, how to reasonably allocate the transmission capacity corresponding to different CA capabilities to achieve the effect of reporting more combinations is an urgent technical problem to be solved.

In order to solve the above technical problem, based on the communication system shown in FIG. 1 , the present application provides a method for transmitting a carrier aggregation capability. Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a method for reporting a carrier aggregation capability provided by an embodiment of the present application. The execution subject of this embodiment is a terminal device, and the method includes steps 310 to 330 as follows.

Step 310, the terminal device receives a capability query request sent by the network device, and the capability query request is used to query multiple CA capabilities of the terminal device.

It should be understood that the capability query request in this embodiment of the present application may be a UECapabilityEnquiry message, and the UECapabilityEnquiry message may carry identifiers of frequency bands corresponding to various CA capabilities. That is to say, the network device may request the multiple CA capabilities from the terminal device by carrying identifiers of frequency bands corresponding to different CA capabilities.

Optionally, multiple CA capabilities may include: EN-DC capability and NR-CA capability; or, NE-DC capability and NR-CA capability; or, EN-DC capability, NE-DC capability and NR-CA capability. The various CA capabilities may also include CA capabilities that need to be reported in the next generation cellular mobile communication system and other mobile communication systems that will be developed later, which is not limited in this embodiment of the present application.

Exemplarily, if the network device needs to query the EN-DC capability and the NR-CA capability, the network device may carry the frequency band identifier of EUTRA and the frequency band identifier of NR in the UECapabilityEnquiry message.

Step 320, the terminal device responds to the capability query request, based on the PLMN information of the cell where it currently resides, and/or, the reporting priority of each CA capability among the multiple CA capabilities, determines the capacity limit threshold corresponding to each CA capability .

It should be understood that after receiving the capability query request, the terminal device may determine the capacity limit threshold corresponding to each capability according to network deployment conditions of different wireless communication technologies in actual applications and/or network requirements.

In a possible implementation manner, capacity limit thresholds corresponding to each CA capability may be formulated for different operators in advance according to network conditions deployed by different operators in an actual network environment. In this way, the terminal device can obtain the capacity limit threshold corresponding to each CA capability among the various CA capabilities queried by the network according to the PLMN information associated with the operator.

Wherein, the PLMN information consists of the MCC and the Mobile Network Code (MNC) of the country where the operator is located. Among them, MCC is uniformly allocated and managed by the International Telecom Union (ITU) worldwide, and is used to uniquely identify different countries in the global mobile communication system, with a total of 3 digits. For example, China's MCC is 460. MNC usually consists of 2 to 3 digits. The MNCs of different operators are different, and the MNCs of mobile networks of different standards of the same operator are also different.

For example, if 60% of the networks deployed by an operator are 5G networks, and the remaining 40% are 4G networks, based on this, you can set the NR-CA capability corresponding to the PLMN information of the operator. The sending capacity threshold is set to 6K, while the sending capacity threshold of the EN-DC capability is 2K.

In another possible implementation, the reporting priorities of multiple CA capabilities may be preset, wherein all the identification information of CA combinations associated with CA capabilities with higher reporting priorities may be reported, and at the same time, the CA capabilities in the capability information The remaining capacity is reserved for the CA combination corresponding to the CA capability with low reporting priority.

That is to say, the capacity limit threshold corresponding to a CA capability with a high reporting priority may be the total data volume of identification information of all CA combinations associated with the CA capability. For the CA capability with a low reporting priority, the corresponding capacity limit threshold can be obtained based on the remaining capacity in the capability information.

Exemplarily, the capacity limit threshold corresponding to the CA capability with a low reporting priority may be the maximum reported capacity value of the capability information minus the total data volume of the CA capability with a high reporting priority. Assuming that the network device inquires about EN-DC capabilities and NR-CA capabilities, when the reporting priority of NR-CA capabilities is higher than that of EN-DC capabilities, all CAs corresponding to the NR-CA capabilities queried by the network can be The combined total data volume (for example, 3K) is used as the capacity limit threshold of the NR-CA capability, and the remaining 5K is used as the capacity limit threshold of the EN-DC capability.

Optionally, the reporting priority of the CA capability in this embodiment of the present application may be determined according to the current network deployment environment. Exemplarily, when the NR technology is immature, the amount of data for the network to query the NR frequency band is much less than the amount of data for querying the EUTRA frequency band in the mature 4G technology. Based on this, the reporting priority of NR-CA capabilities can be set higher than that of EN-DC capabilities, so that all CA combinations corresponding to NR-CA capabilities with a small amount of data can be reported, and the remaining capacity can be reported according to certain rules. Allocate to the CA combination corresponding to the EN-DC capability to obtain the capacity limit threshold of the EN-DC capability.

Optionally, the reporting priorities of different CA capabilities in this embodiment of the present application may also be determined according to the number of frequency bands queried by the network device. Exemplarily, if the network device inquires only two NR frequency bands or only inquires about one NR frequency band in the capability query request, and the number of EUTRA frequency bands to be queried is far greater than the NR frequency bands. Based on this, the reporting priority of NR-CA capabilities can be set higher than that of EN-DC capabilities, so that all CA combinations corresponding to NR-CA capabilities with a small amount of data can be reported, and the remaining capacity can be allocated to EN-DC The CA combination corresponding to the capability.

It can be understood that, in the embodiment of the present application, the capacity limit thresholds corresponding to each CA capability are determined dynamically based on actual network deployment conditions and network requirements. That is to say, the determined capacity limit threshold corresponding to each CA capability may conform to actual network deployment conditions and network requirements.

Step 330, the terminal device sends capability information to the network device based on the capacity limit threshold corresponding to each CA capability; the capability information includes sub-capability information corresponding to each CA capability among the multiple CA capabilities; each CA capability The corresponding sub-capability information is less than or equal to the capacity limit threshold corresponding to the CA capability.

After determining the capacity limit threshold corresponding to each CA capability, the terminal device can send the sub-capability information of each CA capability based on the frequency band of each CA capability queried in the capability query request and the capacity limit threshold of each CA capability .

Wherein, the sub-capability information corresponding to each CA capability may include identification information of some or all CA combinations associated with the CA capability.

Optionally, referring to the schematic flowchart shown in FIG. 4 , step 330 sends capability information to the network device based on the capacity limit threshold corresponding to each CA capability, which may be implemented through the following steps 3301 to 3303 .

Step 3301. Obtain the identification information of the CA combination associated with each CA capability;

Step 3302: Based on the capacity limit threshold corresponding to each CA capability, obtain the identification information of at least one target CA combination from the identification information of multiple CA combinations associated with each CA capability, and obtain sub-capability information corresponding to each CA capability.

Step 3303, sending capability information to the network device; the capability information includes sub-capability information corresponding to each CA capability.

It should be understood that the capability query request may carry frequency band identifiers corresponding to various CA capabilities. The terminal device may obtain all CA combinations associated with each CA capability according to the frequency band identifier corresponding to each CA capability in the capability query request. The CA combination may be a carrier combination corresponding to the frequency band identifier queried by the network device.

After obtaining all CA combinations associated with each CA capability, at least one target CA combination may be selected from all CA combinations associated with the CA capability according to the data amount of the identification information of the CA combination, wherein at least one target CA combination The total data volume of the identification information does not exceed the capacity limit threshold of the CA capability. In this way, the identification information of at least one selected target CA combination is used as the sub-capability information of the CA capability.

Further, the various CA capabilities queried in the capability query request are traversed according to the above method, and the sub-capability information corresponding to each CA capability is obtained, so as to obtain the final capability information UECapabilityInformation.

Optionally, the terminal device may select at least one target CA combination from all the CA combinations associated with the CA capability according to the priority order of each CA combination in the multiple CA combinations associated with the CA capability. In this way, it is ensured that the terminal device reports the important CA combination to the network device as much as possible with limited transmission capacity.

Optionally, if there are multiple CA combinations with the same priority among all the CA combinations associated with a certain CA capability, the terminal device can search from all the CA combinations associated with the CA capability according to the query order of the frequency band in the capability query request. Select the target CA combination.

It can be understood that, in the carrier aggregation capability reporting method provided by the embodiment of the present application, after receiving the capability query request, the terminal device can determine the capacity limit of each CA capability according to the reporting priority of the PLMN and/or CA capability Threshold, in this way, can ensure that the capacity limit threshold corresponding to each CA capability can meet the actual network deployment situation and network requirements, so that the terminal device can reasonably allocate the transmission capacity corresponding to different CA capabilities, and achieve the effect of reporting more combinations.

In an embodiment of the present application, in step 320, based on the PLMN information, the terminal device determines the capacity limit threshold corresponding to each of the various CA capabilities, which can be implemented in the following manner:

Step 3201: Based on the preset mapping relationship, determine the capacity limit threshold of the various CA capabilities associated with the PLMN information; the preset mapping relationship is used to indicate that each PLMN information in the multiple PLMN information is related to each The mapping relationship between the sending capacity thresholds of the CA capabilities;

Wherein, the mapping relationship between each PLMN information and the sending capacity threshold of each CA capability is determined based on the PLMN information corresponding to the operator's network deployment situation.

It can be understood that, in this embodiment of the present application, the sending capacity thresholds corresponding to each CA capability can be respectively configured at an operator's granularity. The terminal device may maintain a preset mapping relationship, and the preset mapping relationship may include a transmission capacity threshold corresponding to each CA capability associated with PLMN information of each operator among multiple operators in the world.

Exemplarily, the preset mapping relationship may be as shown in Table 1:

Table 1

PLMN信息PLMN information	EN-DC能力的容量限制阈值Capacity limit threshold for EN-DC capability	NR-CA能力的容量限制阈值Capacity limit threshold of NR-CA capability
PLMN1PLMN1	4K4K	4K4K
PLMN2PLMN2	2K2K	6K6K
PLMN3PLMN3	8K8K	00

PLMN4

none

3K

In the example in Table 1, the capacity limit threshold of the EN-DC capability corresponding to PLMN1 is 4K, and the capacity limit threshold of the NR-CA capability is 4K. The capacity limit threshold of the EN-DC capability corresponding to PLMN2 is 2K, and the capacity limit threshold of the NR-CA capability is 6K. The capacity limit threshold of the EN-DC capability corresponding to PLMN3 is 8K, and the capacity limit threshold of the NR-CA capability is 0K. The EN-DC capability corresponding to PLMN4 has no associated capacity limit threshold, and the capacity limit threshold of NR-CA capability is 3K.

That is to say, after receiving the capability query request, the terminal device can determine the transmission capacity threshold of each CA capability associated with the PLMN information of the cell where it currently resides by looking up a table.

It should be noted that the sum of the capacity limit thresholds corresponding to the various CA capabilities corresponding to the PLMN information is the maximum reported capacity value of the capability information. In addition, the terminal device may pre-store multiple preset mapping relationships, and the multiple preset mapping relationships may be related to the CA capability queried in the capability query request. The CA capabilities queried in the capability query request are different, and the corresponding preset mapping relationships are different. Exemplarily, if the EN-DC capability and NR-CA capability are queried in the capability query request, the terminal device may determine the capacity limit threshold of the EN-DC capability and the NR-CA capability according to a first preset mapping relationship, wherein the first In the preset mapping relationship, the sum of the capacity limit thresholds of the EN-DC capability and the NR-CA capability associated with each type of PLMN information is 8K. If the EN-DC capability, NR-CA capability, and NE-DC capability are inquired in the capability query request, the terminal device can determine the capacity limit thresholds corresponding to the above three capabilities according to the second preset mapping relationship, wherein, in the first In the two preset mapping relationships, the sum of the EN-DC capability, NR-CA capability and NE-DC capacity limit thresholds associated with each type of PLMN information is 8K.

In the embodiment of the present application, the mapping relationship between each PLMN information in the above preset mapping relationship and the transmission capacity threshold of each CA capability is determined based on the network deployment situation of the operator corresponding to the PLMN information. Optionally, the application server can obtain official network deployment information of operators around the world, fully consider the network compatibility of different operators, and formulate capacity limit thresholds corresponding to each CA capability for different operators.

It should be understood that, in this embodiment of the present application, the terminal device may receive the foregoing preset mapping relationship sent by the application server through an over-the-air technology (OTA).

Optionally, the terminal device may acquire the preset mapping relationship from the application server at preset time intervals;

Alternatively, when the terminal device detects that the version information of the preset mapping relationship changes, it acquires the latest version of the preset mapping relationship from the application server.

That is to say, the preset mapping relationship can be changed according to the change of the operator's network deployment situation, and the terminal device can update the preset mapping relationship through OTA, and dynamically adjust the correspondence of each CA capability associated with multiple PLMN information. The capacity limit threshold for better adaptation to the network.

Optionally, if the PLMN information is associated with the capacity limit thresholds of some of the CA capabilities among the multiple CA capabilities, then determine other The capacity limit threshold of the CA capability.

It should be noted that in the preset mapping relationship, there is a case where the capacity limit threshold of the CA capability of the PLMN information association part is present. That is to say, some operator networks only have restrictions on the transmission capacity of some CA capabilities. For example, in Table 1, the capacity limit threshold of PLMN4 associated with NR-CA capability has no corresponding capacity limit threshold of EN-DC capability.

Based on this, the terminal device can calculate the difference between the maximum reported capacity value and the capacity limit threshold of some CA capabilities, and allocate the remaining capacity to the other CA capabilities, so as to obtain the transmission capacity thresholds of the other CA capabilities. For example, in Table 1, PLMN4 is only associated with the capacity limit threshold of NR-CA capability, and the capacity limit threshold of NR-CA capability is 3K. Therefore, theoretically, the capacity limit threshold of the EN-DC capability corresponding to the PLMN4 can be 5K (ie, 8K-3K).

It should be noted that, if the other CA capabilities include multiple types, the terminal device may evenly allocate the remaining capacity to the multiple CA capabilities.

In an embodiment of the present application, step 3201 determines the capacity limit thresholds of the various CA capabilities associated with the PLMN information based on the preset mapping relationship, which may also be implemented through the following steps 3201a and 3201b:

Step 3201a, based on a preset mapping relationship, determine the initial capacity limit thresholds of the various CA capabilities associated with the PLMN information;

Step 3201b, if the data volume of the CA combination identification information associated with the first CA capability is less than the initial capacity limit threshold of the first CA capability, and the data volume of the CA combination identification information associated with the second CA capability is larger than the first CA The initial capacity limit threshold of the capability, based on the data amount of the identification information of the CA combination associated with each capability, the initial capacity limit threshold corresponding to each CA capability is updated to obtain the corresponding Capacity limit threshold.

Wherein, the first CA capability and the second CA capability are two different CA capabilities among multiple CA capabilities requested by the network device.

It should be understood that through the preset mapping relationship, the determined capacity limit thresholds of various CA capabilities associated with the PLMN information are fixed values, which cannot well meet actual needs in some special environments.

Exemplarily, according to the PLMN, it is determined that the capacity limit threshold of the NR-CA capability is 4K, and the capacity limit threshold of the EN-DC capability is 4K. However, in fact, the network device inquires about one frequency band of NR (for example, the data volume of the identification information of the corresponding CA combination is 1K), and inquires about frequency bands of multiple EN-DC capabilities (for example, the data volume of the identification information of the corresponding CA combination is 5K). Therefore, continuing to send capability information according to the capacity limit threshold of the 4K NR-CA capability and the capacity limit threshold of the 4K EN-DC capability determined by the PLMN will lead to insufficient reporting of the EN-DC capability.

Based on this, in this embodiment of the application, the data volume of the CA combination identification information associated with the first CA capability of the terminal device is less than the initial capacity limit threshold of the first CA capability, and the data volume of the CA combination identification information associated with the second CA capability If it is greater than the initial capacity limit threshold of the first CA capability, the initial capacity limit threshold of each CA capability may be dynamically adjusted according to the amount of data actually required by each CA capability, and as many CA combinations as possible may be reported .

Exemplarily, if it is determined according to the PLMN that the initial capacity limit threshold of the NR-CA capability is 4K, the initial capacity limit threshold of the EN-DC capability is 4K. However, in fact, the network device inquires about one frequency band of NR (for example, the data volume of the identification information of the corresponding CA combination is 1K), and inquires about frequency bands of multiple EN-DC capabilities (for example, the data volume of the identification information of the corresponding CA combination is 5K). Based on this, the terminal device can adjust the capacity limit threshold of the EN-DC capability to 7K, and adjust the capacity limit threshold of the NR-CA capability to 1K, so as to ensure that the CA combination of the EN-DC capability can be fully reported. Of course, the terminal device can also adjust the capacity limit threshold of the EN-DC capability to 6K, and adjust the capacity limit threshold of the NR-CA capability to 2K, as long as the CA combination of the EN-DC capability can be fully reported, this application implements The example does not limit the adjustment method.

In an embodiment of the present application, in step 320, based on the reporting priority of each CA capability in multiple CA capabilities, the capacity limit threshold corresponding to each CA capability is determined, which can be implemented in the following manner:

Step 3202, the terminal device uses the total data volume of identification information of all CA combinations associated with each third CA capability among multiple third CA capabilities as the transmission capacity threshold corresponding to the third CA capability; the third CA capability Including CA capabilities other than the fourth CA capability among the multiple CA capabilities; the fourth CA capability is the CA capability with the lowest reporting priority among the multiple CA capabilities;

Step 3203. The terminal device determines the capacity limit threshold of the fourth CA capability based on the maximum reported capacity value of the capability information and the capacity limit threshold corresponding to each third CA capability.

It should be understood that the third CA capability may be a CA capability with a higher reporting priority among the various CA capabilities queried by the network device, that is, the third CA capability is a non-lowest priority CA capability among the multiple CA capabilities queried by the network device. The third CA capability may include one or more, which is not limited in this embodiment of the present application.

Here, the terminal device may report the identification information of all CA combinations associated with the CA capability with higher priority (the third CA capability) (that is, the total data volume of all CA combinations associated with the CA capability with higher priority as The capacity limit threshold of the CA combination), and allocate the remaining capacity in the reported capability information to the CA capability with the lowest priority (the fourth CA capability) according to certain rules, and obtain the capacity limit threshold of the CA capability with the lowest priority . In this way, it is ensured that the CA combination corresponding to the important CA capability can be completely reported to the network device.

Optionally, the reporting priority of the CA capability in this embodiment of the present application may be determined according to the current network deployment environment. Exemplarily, when the NR technology is immature, the amount of data for the network to query the NR frequency band is much less than the amount of data for querying the EUTRA frequency band in the mature 4G technology. Based on this, the reporting priority of the NR-CA capability can be set higher than that of the EN-DC capability, so that the CA combination corresponding to the NR-CA capability with a small amount of data is reported first, and the remaining capacity is allocated to the EN-DC The CA combination corresponding to the capability.

Optionally, the reporting priorities of different CA capabilities in this embodiment of the present application may also be determined according to the number of frequency bands queried by the network device. Exemplarily, if the network device inquires only two NR frequency bands or only inquires about one NR frequency band in the capability query request, and the number of EUTRA frequency bands to be queried is far greater than the NR frequency bands. Based on this, the reporting priority of the NR-CA capability can be set higher than that of the EN-DC capability, so that the CA combination corresponding to the NR-CA capability with a small amount of data is reported first, and the remaining capacity is allocated to the EN-DC The CA combination corresponding to the capability.

That is to say, in this embodiment of the application, the third CA capability with higher priority needs to report less information. In order to ensure that the terminal device can fully report the CA combinations associated with multiple CA capabilities, the third CA capability can be associated with the third CA capability first. report all the CA combinations, and allocate the remaining capacity in the capability information to the capability of the fourth CA for reporting.

It can be understood that the sum of the capacity limit thresholds of the above multiple CA capabilities (including multiple third CA capabilities and fourth CA capabilities) may be the maximum reported capacity value of the capability information.

In this embodiment of the present application, the capacity limit threshold corresponding to the third CA capability may be the total data volume of identification information of all CA combinations associated with the third CA capability. There are many ways to determine the capacity limit threshold corresponding to the fourth CA capability, two of which are described in detail below.

method one:

Optionally, the terminal device determines the capacity limit threshold of the fourth CA capability based on the maximum reported capacity value of the capability information and the capacity limit threshold corresponding to each third CA capability, which may be implemented in the following manner:

The terminal device may use the difference between the maximum reported capacity value and the sum of the capacity limit thresholds corresponding to multiple CA capabilities as the capacity limit threshold of the fourth CA capability.

It can be understood that the terminal device may calculate the difference between the maximum reported capacity value and the sum of the capacity limit thresholds corresponding to the multiple third CA capabilities to obtain the capacity limit threshold of the fourth CA capability. That is to say, after determining the total data volume of the identification information of the CA combination corresponding to each third CA capability, the terminal device allocates all the remaining capacity in the capability information to the fourth CA capability. That is to say, the capacity limit threshold of the fourth CA capability may be the remaining capacity value after removing the CA combinations that are reported preferentially.

Exemplarily, if the network device queries the EN-DC capability and the NR-CA capability in the capability query request. Wherein, the network device inquires about one NR frequency band, but inquires about multiple EUTRA frequency bands. Considering that the number of NR frequency bands inquired by network devices is small (that is, the amount of identification information data of CA combinations that need to be reported by NR-CA capabilities is small, such as 1K), based on this, the reporting priority of NR-CA capabilities can be set higher than that of The reporting priority of the EN-DC capability shall give priority to the reporting of the NR capability. Wherein, the terminal device may use the total data amount (1K) of the identification information of the CA combination corresponding to NR-CA as the capacity limit threshold of the NR-CA capability, and use the remaining 7K as the capacity limit threshold of the EN-DC capability. That is to say, the data volume of the identification information of the CA combination corresponding to the EN-DC capability carried by the terminal device in the capability information does not exceed 7K.

It should be noted that the sum of the capacity limit thresholds of the plurality of third CA capabilities and the capacity limit threshold of the fourth CA capability is the maximum reported capacity value.

Method 2:

Optionally, the terminal device determines the capacity limit threshold of the fourth CA capability based on the maximum reported capacity value of the capability information and the capacity limit threshold corresponding to each third CA capability, which may also be implemented in the following manner:

Based on the sum of the capacity limit thresholds corresponding to the multiple third CA capabilities, and the preset ratio parameter, determine the capacity limit threshold of the fourth CA capability; the preset ratio parameter represents the sum of the capacity limit thresholds of the multiple third CA capabilities and the first The ratio of the capacity limit thresholds of the four CA capabilities.

In practical applications, when different CA capabilities report the identification information of the CA combination, there is a situation of repeated reporting. For example, some CA combinations associated with the EN-DC capability may overlap with some CA combinations associated with the NR-CA capability. Therefore, the terminal device can allocate transmission capacity for different CA capabilities in proportion.

In the embodiment of the present application, the ratio between the sum of the capacity restriction thresholds corresponding to the third CA capabilities and the capacity restriction thresholds corresponding to the fourth CA capabilities conforms to the preset ratio parameter.

Wherein, the preset ratio parameter can be any one of a variety of ratio parameters, for example, the preset ratio parameter can be 1:1, 1:2, 1:3, etc., which one of the preset ratio parameters can be selected according to the actual Situation settings. The general principle is that the sum of the capacity limit thresholds corresponding to the multiple third CA capabilities and the capacity limit thresholds corresponding to the fourth CA capability does not exceed the maximum reported capacity value of the terminal device capability information.

Exemplarily, since the NR network is not yet mature, the NR band of the network query is limited. The priority of NR-CA capability can be set higher than that of EN-DC capability. That is to say, all the CA combinations associated with the NR-CA capability can be reported, and the remaining capacity is allocated to the EN-DC capability in proportion. If the data volume of the identification information of all CA combinations associated with the NR-CA capability is less than 2K, select the preset ratio parameter as 1:3 (NR CA:MR-DC), and thus determine the capacity limit threshold of the EN-DC capability to be 6K , that is, the total data volume of the reported identification information of the CA combination associated with the EN-DC capability does not exceed 6K. If the data volume of the identification information of all CA combinations associated with the NR-CA capability is between 2-2.65K, select the preset ratio parameter as 1:2 (NR CA:MR-DC), which determines the capacity of the EN-DC capability The limit threshold is 5K. If the data volume of the identification information of all CA combinations associated with the NR-CA capability is between 2.65-4K, select the preset ratio parameter as 1:1 (NR CA:MR-DC), thereby determining the capacity of the EN-DC capability The limit threshold is 4K.

The above describes that the terminal device determines the capacity limit threshold corresponding to each CA capability based on the PLMN information alone, or determines the capacity limit threshold corresponding to each CA capability based on the reporting priority of each CA capability among multiple CA capabilities. In some embodiments, the terminal device may also determine the capacity limit threshold corresponding to each CA capability based on the PLMN information and the reporting priority of each CA capability among the multiple CA capabilities.

In an embodiment of the present application, referring to the schematic flowchart shown in FIG. 5 , in step 320, the terminal device determines the capacity corresponding to each CA capability based on the PLMN information and the reporting priority of each CA capability among the multiple CA capabilities Limiting the threshold can be achieved by the following steps:

Step 3204: If the PLMN information is associated with the capacity limit threshold of at least one of the multiple CA capabilities, then based on the PLMN information, determine the capacity limit threshold corresponding to each of the CA capabilities;

Step 3305: In the case that the PLMN information is not associated with the capacity limit threshold of at least one of the multiple CA capabilities, if the queried total of the identification information of all CA combinations associated with the multiple CA capabilities If the amount of data is greater than the maximum reported capacity value, the capacity limit threshold corresponding to each CA capability is determined based on the reporting priority of each CA capability among the multiple CA capabilities.

It can be understood that, after receiving the capability query request, the terminal device may first check whether the PLMN information of the cell where it currently resides sets a corresponding capacity limit threshold for the requested CA capability. If the PLMN information is associated with the capacity limit threshold of at least one CA capability, the terminal device can use the capacity limit threshold of at least one CA capability associated with the PLMN information to obtain the value of each CA capability among the various CA capabilities queried by the network device. Capacity limit threshold.

It should be noted that the terminal device can use the capacity limit threshold of at least one CA capability associated with the PLMN information to obtain the capacity limit threshold of each of the various CA capabilities inquired by the network device in the same manner as the description in the above embodiment , which will not be repeated here.

In addition, when the PLMN information of the resident cell does not set the capacity limit threshold of the CA capability, in principle, it is necessary to report as many CA combinations as possible. Can be divided into the following two cases for discussion.

Case 1: If multiple CA capabilities can be fully reported, that is, the total data volume of the identification information of the CA combination associated with multiple CA capabilities is less than or equal to the maximum reporting capacity value of the capability information.

In this case 1, the terminal device may not set the sending capacity threshold of each CA capability, but directly report all the identification information of the CA combination associated with multiple CA capabilities queried by the network device.

Case 2: If multiple CA capabilities are not fully reported, that is, the total data volume of the identification information of the CA combination associated with the queried multiple CA capabilities is greater than the maximum reported capacity value of the capability information.

In this case 2, the terminal device may determine the capacity limit threshold corresponding to each CA capability based on the reporting priority of each CA capability among the multiple CA capabilities.

Here, the manner in which the terminal device determines the capacity limit threshold corresponding to each CA capability based on the reporting priority of each CA capability among the multiple CA capabilities is the same as that in the foregoing embodiment, and will not be repeated here.

To sum up, in the carrier aggregation capability reporting method provided by the embodiment of the present application, after receiving the capability query request, the terminal device can determine the capacity limit of each CA capability according to the reporting priority of the PLMN and/or CA capability Threshold, in this way, can ensure that the capacity limit threshold corresponding to each CA capability can meet the actual network deployment situation and network requirements, so that the terminal device can reasonably allocate the transmission capacity corresponding to different CA capabilities, so as to achieve the effect of reporting more combinations and enhance the User experience.
