Description

Method and equipment for sending and receiving capability information
Technical Field
The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for sending and receiving capability information.
Background
With the fifth generation mobile communication technology (the 5)thgeneration, 5G), in the deployment of operators, a base station operating in a Long Term Evolution (LTE) system and a base station operating in a 5G New Radio (NR) system may be configured to communicate with a terminal device together, that is, the terminal device may be connected to the base station operating in the LTE system (hereinafter, referred to as LTE base station) at the same time) And a base station operating in the NR system (hereinafter, referred to as an NR base station), so that data can be transmitted using both the frequency of the LTE system and the frequency of the NR system, thereby improving the throughput of the terminal device. Such a scenario, in which a terminal device is simultaneously connected to base stations of two different access technologies, may be referred to as multi-RAT dual connectivity (MR-DC).
For the terminal devices, some terminal devices may support the MR-DC scenario, and some terminal devices may not support the MR-DC scenario, so that the terminal devices may transmit the capability information of the terminal devices to the base station in advance, and the base station may determine which scenarios the terminal devices can operate in.
Currently, for a terminal device supporting MR-DC capability, when sending capability information of the terminal device to a base station, the capability information is sent in three parts, namely, capability information of the terminal device under LTE, capability information of the terminal device under NR, and capability information of the terminal device under MR-DC. And the capability information of the terminal device under MR-DC may include a combination relationship between the capability information of the terminal device under NR and the capability information under LTE, for example, the terminal device supports NR band (band) combination 1 under NR and LTE band combination 1 under LTE, and one combination relationship supported by the terminal device under MR-DC is NR band combination 1 and LTE band combination 1, and the capability information of the terminal device under MR-DC may include the capability information of NR band combination 1 and the capability information of corresponding LTE band combination 1. However, when transmitting the capability information under NR, the terminal device may transmit the capability information of NR band combination 1, when transmitting the capability information under LTE, the terminal device may transmit the capability information of LTE band combination 1, and when transmitting the capability information under MR-DC, the terminal device may again transmit the capability information of NR band combination 1 and the capability information of LTE band combination 1, which obviously causes repeated transmission, resulting in a large system overhead.

That is, the network device may instruct the terminal device not to repeatedly send the same capability information in advance, and the terminal device may send the capability information to the network device according to a request of the network device, so as to meet a requirement of the network device. For example, the request message may multiplex a message that is already in the prior art, for example, the request message may be a message for requesting the terminal device for capability information of the terminal device. The embodiment of the application multiplexes the message, so that the message can be used for requesting the terminal equipment for the capability information of the terminal equipment, and can also indicate the terminal equipment not to repeatedly send the same capability information, thereby improving the utilization rate of the message.

The network device may further include a core network device, wherein the core network device referred to herein may correspond to different devices in different communication systems, for example, in the fourth generation mobile communication technology (the 4)thgeneration, 4G) system, the core network device referred to herein may be a Mobility Management Entity (MME) or other core network devices, and in the 5G system, the core network device referred to herein may be an access and mobility management function (AMF) or other core network devices.
In addition, if not specifically stated, the network devices described below are all referred to as access network devices.
3) The capability of the terminal device, which may also be understood as the access capability of the terminal device, may be embodied by capability information of the terminal device, where if the terminal device is implemented by a UE, the capability information of the terminal device may also be referred to as UE capability information, or may also be referred to as UE access capability (access capability). The capability information of the terminal device includes, for example: packet Data Convergence Protocol (PDCP) parameters, physical layer parameters, radio frequency parameters, measurement parameters, and the like, where the radio frequency capabilities may include band combination (band combination) supported by the terminal device, and a modulation mode, multiple-input multiple-output (MIMO) capability, bandwidth, subcarrier spacing (SCS) and the like supported by the terminal device on carriers of the band combination.

Of course, the capability parameters or the capability information are exemplary capability parameters or capability information, and the capability information of the terminal device may include one or more of the capability parameters and one or more of the capability information, and the specific and complete capability information is not described herein again. In addition, in the embodiment of the present application, description is mainly made regarding the capability of band combination of the terminal device, and therefore, hereinafter, description is mainly made of capability information of band combination of the terminal device.
In addition, the capability information sent by the terminal device to the network device may include capability information of multiple radio access technologies of the terminal device. If the terminal device supports one radio access technology, the terminal device will have capability information corresponding to the radio access technology, and the capability information is the capability information of the radio access technology of the terminal device, or it is understood that the capability information of one radio access technology of the terminal device is the capability information of the terminal device when the terminal device works under one radio access technology. Alternatively, the capability information of one radio access technology of the terminal device may be described as the capability information of the terminal device under one radio access technology. The radio access technologies include, for example: NR, LTE-NR, Universal Mobile radio Access terrestrial (UTRA), enhanced data rates for GSM evolution (GSM EDGE radio Access network, GERAN), and Code Division Multiple Access (CDMA) 2000-1XRTT, and possibly other radio access technologies. The LTE-NR capability comprises the capability supported on the LTE side and the NR side when the terminal device works by using the LTE technology and the NR technology simultaneously.
4) MR-DC, with the development of 5G, in the deployment of operators, a base station operating in LTE system and a base station operating in 5G NR system can be configured to communicate with a terminal device together, that is, the terminal device can be connected to the LTE base station and the NR base station at the same time, so that data can be transmitted by using both the frequency of LTE system and the frequency of NR system, thereby improving the throughput of the terminal device. The scenario in which such a terminal device is connected to base stations of two different access technologies simultaneously may be referred to as MR-DC.
When the terminal device is connected to the LTE base station and the NR base station at the same time, if the LTE base station is used as a master base station and the NR base station is used as a slave base station, the scenario is specifically referred to as LTE-NR dual connectivity (EN-DC) in MR-DC; whereas if the NR base station is the primary base station and the LTE base station is the secondary base station, this scenario is specifically referred to as NR-LTE dual connectivity (NE-DC) in MR-DC. In this document, the NE-DC is mainly used as an example for description, that is, the terminal device may send capability information of the terminal device under the NE-DC to the network device.
5) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "plurality" means two or more, and in view of this, a plurality is also understood as "at least two", for example, two, three or more, in the embodiments of the present application. "at least one", such as one, two, three or more, for example, "at least one frequency band combination", may include one frequency band combination, two frequency band combinations, three frequency band combinations or more frequency band combinations. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first capability information and the second capability information are only for distinguishing different capability information, and do not indicate a difference in priority, importance, or the like between the two types of capability information.
Having described some concepts related to embodiments of the present application, the following description will be made of the features of embodiments of the present application, and the following description will be made in detail with reference to fig. 1.
Fig. 1 is a process of reporting capability information to a network device by a terminal device. This procedure may occur in a radio resource control connection setup procedure (radio resource control connection setup procedure) of the terminal device. In addition, the process is applied to a 4G system as an example, and therefore, the core network device is an MME as an example.
S11, the access network device sends an initial UE message (initial UE message) to the MME, and the MME receives the initial UE message from the access network device.
After the RRC connection between the terminal device and the access network device is established, the access network device sends an initial UE message to the MME.
S12, the MME sends a UE context setup request (UE context setup request) to the access network device, and the access network device receives the UE context setup request from the MME.
After receiving the initial UE message, the MME checks whether the capability information of the terminal device (i.e., the UE) is stored locally, and if the capability information of the terminal device is stored locally, the MME sends the capability information of the terminal device to the access network device in a UE context setup request, and if the capability information of the terminal device is not stored locally, the MME does not include the capability information of the terminal device in the UE context setup request.
Then, if the UE context setup request received by the access network device includes the capability information of the terminal device, S13 is executed, and if the UE context setup request received by the access network device does not include the capability information of the terminal device, S14 is executed.
And S13, the access network equipment stores the capability information of the terminal equipment.
The access network device may utilize the capability information of the terminal device to communicate with the terminal device. The process may now be considered to be complete.
S14, the access network device sends a UE capability request (UE capability request) message to the terminal device, and the terminal device receives the UE capability request message from the access network device.
Because the UE context setup request received by the access network device does not include the capability information of the terminal device, the access network device may request the terminal device for obtaining the capability information of the terminal device.
S15, the terminal device sends a UE capability information (UE capability information) message to the access network device, and the access network device receives the UE capability information message from the terminal device.
The UE capability information message includes capability information of the terminal device. Currently, when sending capability information of a terminal device to a network device, the terminal device divides the capability information into three parts to send, where the three parts are capability information of the terminal device under LTE, capability information of the terminal device under NR, and capability information of the terminal device under MR-DC. Wherein the capabilities under LTE comprise at least the combinations of frequency bands supported by the terminal device under LTE, the capabilities under NR comprise at least the combinations of frequency bands supported by the terminal device under NR, and the capabilities under MR-DC comprise at least the combinations of frequency bands supported by the terminal device when LTE and NR are simultaneously operating. Please refer to fig. 2, which is a schematic diagram of a terminal device sending capability information of the terminal device under LTE to a network device. For example, the terminal device supports a band combination 1 and a band combination 2 under LTE, the band combination 1 includes bands 1 to X, X may be greater than 3 in the example of fig. 2, one carrier is included under the band 1, 2 carriers are included under the band 2, 3 carriers are included under the band 3, and X carriers are included under the band X, for example, the band combination capability information of the terminal device under LTE may include at least one of bandwidth, subcarrier spacing, modulation scheme, Channel State Information (CSI) processing capability (process capability) or multiple-input multiple-output (MIMO) capability, which correspond to the carriers respectively. Similarly, the band combination 2 includes several bands from the band 1 to the band Y, in the example of fig. 2, Y may be greater than 2, one carrier is included in the band 1, 5 carriers are included in the band 2, and for example, Y carriers are included in the band Y, and then the band combination capability information of the terminal device in LTE also includes at least one of bandwidth, subcarrier spacing, modulation scheme, CSI capability, MIMO capability, and the like corresponding to the carriers respectively.
The terminal device sends the terminal device the band combination capability information under NR and the band combination capability information under NE-DC to the network device in a similar manner, wherein if the terminal device is the capability information under NE-DC, the corresponding band combination capability information of LTE and the band combination capability information of NR are included in the same manner as shown in fig. 2.
For example, please refer to fig. 3, which is a schematic diagram of the terminal device dividing the capability information of the terminal device into three parts for transmission, where the three parts are the capability information of the terminal device under LTE, the capability information of the terminal device under NR, and the capability information of the terminal device under MR-DC. For example, the terminal device sends the three pieces of capability information in a message, such as the UE capability information message in S15, and the UE capability information message is, for example, a Radio Resource Control (RRC) message. The three parts are located in 3 containers (containers) in the UE capability information message, and one container can be understood as a field, where the capability information of the terminal device under LTE is located in LTE container, the capability information of the terminal device under NR is located in NR container, and the capability information of the terminal device under NE-DC is located in MR-DC container. It can be seen in fig. 3 that the LTE container includes an LTE band combination list (LTE bandcombination list) of the terminal device, that is, a list of band combinations supported by the terminal device under LTE, the NR container includes an NR band combination list (NR bandcombination list) of the terminal device, that is, a list of band combinations supported by the terminal device under NR, and the MR-DC container includes a correspondence relationship between the band combinations supported by the terminal device under LTE and the band combinations supported by the terminal device under NR, or such a correspondence relationship may also be referred to as an MR-DC band combination. For example, the MR-DC band combinations supported by the terminal device include MR-DC band combination 1 to MR-DC band combination x, the band combinations supported by the terminal device under LTE include LTE band combination 1 to LTE band combination x, and the band combinations supported by the terminal device under NR include NR band combination 1 to NR band combination y, where MR-DC band combination 1 includes LTE band combination 1 and NR band combination 1, MR-DC band combination 2 includes LTE band combination 2 and NR band combination 2, and so on. Therefore, the capability information of LTE band combination 1, the capability information of NR band combination 1, the capability information of LTE band combination 2, and the capability information of NR band combination 2 are also included in the MR-DC Container, where the contents of the LTE Container and the MR-DC Container can be interpreted by the LTE base station, and the contents of the NR Container and the MR-DC Container can be interpreted by the NR base station. It can be seen that, for either the LTE base station or the NR base station, the terminal device repeatedly transmits the capability information of the partial frequency band combination.
And S16, the access network equipment stores the capability information of the terminal equipment.
The access network device may utilize the capability information of the terminal device to communicate with the terminal device. For example, after the network device receives the UE capability information message, the network device may configure the PDCP configuration, the physical layer configuration, the radio frequency configuration, the measurement configuration, and the like of the terminal device according to the capability information of the terminal device, so as to ensure that the configuration of the terminal device can meet the capability of the terminal device itself, that is, the terminal device can normally operate under the configuration of the network device.
S17, the access network device sends a UE capability information indication (UE capability information) to the MME, and the MME receives the UE capability information indication from the access network device.
Because the MME does not store the capability information of the terminal device, the access network device may send a UE capability information indication to the MME, where the UE capability information indication may include the capability information of the terminal device.
And S18, the MME stores the capability information of the terminal equipment.
As can be seen from the process shown in fig. 1, when the terminal device sends the capability information of the terminal device to the network device, there may be a situation of repeated sending, which results in a large amount of information sent by the terminal device and also increases the system overhead.
In view of this, in the embodiment of the present application, if it is determined that the first capability information includes capability information of a first frequency band combination of the terminal device in the first radio access technology, the second capability information determined by the terminal device does not include capability information of the first frequency band combination of the terminal device in the first radio access technology, which is equivalent to that the same capability information is only sent once, and repeated sending is reduced as much as possible, thereby saving system overhead.
The technical solution provided in the embodiment of the present application may be applied to a 5G system, or an LTE system, or may also be applied to a next generation mobile communication system or other similar communication systems, which is not limited specifically.
A network architecture applied in the embodiment of the present application is described below, please refer to fig. 4.
Fig. 4 includes a network device and a terminal device, and the terminal device is connected to one network device. Of course, the number of the terminal devices in fig. 4 is only an example, in an actual application, the network device may provide services for a plurality of terminal devices, and the network device may configure N configuration parameter sets for all or part of the terminal devices in the plurality of terminal devices.
The network device in fig. 4 is, for example, an access network device, such as a base station. The access network device corresponds to different devices in different communication systems, for example, may correspond to an eNB in a 4G system, and may correspond to an access network device in a 5G system, for example, a gNB in a 5G system.
The technical scheme provided by the embodiment of the application is described below with reference to the accompanying drawings.
An embodiment of the present application provides a method for sending and receiving capability information, please refer to fig. 5, which is a flowchart of the method. In the following description, the method is applied to the network architecture shown in fig. 4 as an example. In addition, the method may be performed by two communication apparatuses, for example, a first communication apparatus and a second communication apparatus, where the first communication apparatus may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or the first communication apparatus may be a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and may of course be other communication apparatuses such as a system on chip. The same applies to the second communication apparatus, which may be a network device or a communication apparatus capable of supporting the network device to implement the functions required by the method, or a terminal device or a communication apparatus capable of supporting the terminal device to implement the functions required by the method, and of course, other communication apparatuses such as a system on a chip may also be used. The implementation manners of the first communication device and the second communication device are not limited, for example, the first communication device may be a network device, the second communication device is a terminal device, or both the first communication device and the second communication device are network devices, or both the first communication device and the second communication device are terminal devices, or the first communication device is a network device, and the second communication device is a communication device capable of supporting the terminal device to implement the functions required by the method, and so on. The network device is, for example, a base station.
For convenience of introduction, in the following, the method is performed by a network device and a terminal device as an example, that is, the first communication apparatus is a terminal device, and the second communication apparatus is a network device as an example. Since the method is applied to the network architecture shown in fig. 4 as an example, the network device described below may be a network device in the network architecture shown in fig. 4, and the terminal device described below may be a terminal device in the network architecture shown in fig. 4.
S51, the terminal device determines that first capability information of the terminal device includes capability information of a first frequency band combination of the terminal device in a first radio access technology, where the first capability information is a combination of the capability information of the frequency band combination of the terminal device in the first radio access technology and the capability information of the frequency band combination of the terminal device in a second radio access technology;
s52, the terminal device determines second capability information of the terminal device, where the second capability information is capability information of a band combination of the terminal device in the first radio access technology, and the second capability information does not include capability information of the first band combination of the terminal device in the first radio access technology, and is included in the first capability information;
s53, the terminal device sends the first capability information and the second capability information of the terminal device to a network device, and the network device receives the first capability information and the second capability information of the terminal device from the terminal device;
s54, the network device obtains capability information of a band combination of the terminal device in the first radio access technology according to the first capability information and the second capability information.
The first capability information is a combination of capability information of a frequency band combination of the terminal device under the first radio access technology and capability information of a frequency band combination of the terminal device under the second radio access technology, wherein the combination of the capability information is used for expressing the capability of the frequency band combination supported by the terminal device when the first radio technology and the second radio technology work simultaneously. For example, if the terminal device supports band combination 1 in the first radio access technology and band combination 2 in the second radio access technology, the combination of the one piece of capability information included in the first capability information may be band combination 1 and band combination 2. The band combination includes a band combination using the first rat as a master station and/or a band combination using the second rat as a master station, that is, a band combination using the first rat as a master station or a band combination using the second rat as a master station, or a band combination using the first rat as a master station and a band combination using the second rat as a master station.
The first capability information includes, for example, EN-DC capability information of the terminal device or NE-DC capability information of the terminal device, the second capability information includes, for example, NR capability information of the terminal device, and the first radio access technology is NR, or the second capability information includes LTE capability information of the terminal device, and the first radio access technology is LTE. For convenience of description, in this embodiment, the first capability information includes NE-DC capability information of the terminal device, the second capability information includes NR capability information of the terminal device, and the first radio access technology is NR. The NR capability information of the terminal device refers to capability information of a frequency band combination of the terminal device under NR, the LTE capability information of the terminal device refers to capability information of a frequency band combination of the terminal device under LTE, the NE-DC capability information of the terminal device refers to capability information of a frequency band combination of the terminal device under NE-DC, and the EN-DC capability information of the terminal device refers to capability information of a frequency band combination of the terminal device under EN-DC.
The terminal device may determine the first capability information of the terminal device, that is, determine NE-DC capability information of the terminal device, for example, the NE-DC capability information of the terminal device may be understood as including at least one capability information combination, one capability information combination represents a combination relationship between capability information of one LTE band combination and capability information of one NR band combination, or one capability information combination includes one LTE band combination and one NR band combination, and then the NE-DC capability information of the terminal device may include at least one such capability information combination, that is, the NE-DC capability information of the terminal device may include one capability information combination, two capability information combinations, or more capability information combinations. Wherein, a capability information combination represents a complete NE-DC capability, the terminal device can support one of the NE-DC capabilities at one time, and can support different NE-DC capabilities included in the NE-DC capability information at different times, that is, can realize the capabilities corresponding to different capability information combinations included in the NE-DC capability information at different times.
Since the NE-DC capability information of the terminal device may include the capability information of the LTE band combination and the capability information of the NR band combination, which is a part of or all of the NR capability information of the terminal device, when determining the NR capability information of the terminal device, the terminal device does not need to include the NR capability information included in the NE-DC capability information, that is, the second capability information determined by the terminal device may not include the capability information of the band combination of the terminal device under NR included in the first capability information, or in brief, the second capability information determined by the terminal device may not include the capability information included in the first capability information, that is, the second capability information does not include the capability information included in the first capability information, Capability information of a band combination of the terminal device in the first radio access technology. For example, the first capability information includes capability information of the first frequency band combination of the terminal device under NR, and the second capability information does not include capability information of the first frequency band combination of the terminal device under NR. Wherein the first band combination may comprise one or more band combinations.
Alternatively, for S51, s52 and S53 may also be described as the terminal device determining capability information of a first band combination of the terminal device in the first radio access technology and capability information of a second band combination of the terminal device in the second radio access technology, the terminal device sending the first capability information and the second capability information of the terminal device to the network device, the first capability information being a combination of the capability information of the band combination of the terminal device in the first radio access technology and the capability information of the band combination of the terminal device in the second radio access technology, the second capability information being capability information of the band combination of the terminal device in the first radio access technology, the first capability information including the capability information of the first band combination of the terminal device in the first radio access technology, and the second capability information including the capability information of the second band combination supported by the terminal device in the first radio access technology. The first band combination may include one or more band combinations and the second band combination may include one or more band combinations. That is, the capability information of the frequency band combination of the terminal device under the first radio access technology includes the capability information of the first frequency band combination and the capability information of the second frequency band combination, and the capability information of the first frequency band combination is also included in the first capability information, so that the second capability information does not include the capability information of the first frequency band combination any more, but only includes the capability information of the second frequency band combination. Taking the first capability information as NE-DC capability information, the second capability information as NR capability information, and the first radio access technology as NR as an example, for example, if the capability information of the terminal device determining the band combination of the terminal device under NR includes the capability information of NR band combination 1 and the capability information of NR band combination 2, and where the capability information of NR band combination 1 is included in the NE-DC capability information of the terminal device, the capability information of NR band combination 1 is no longer included in the NR capability information of the terminal device, but only the capability information of NR band combination 2 is included.
For example, referring to table 1, an example of NE-DC capability information of a terminal device is shown:
TABLE 1
LTE band combination 1 NR band combination 1
LTE band combination 2 NR band combination 2
LTE band combination 3 NR band combination 3
One row in table 1 indicates one capability information combination, for example, LTE band combination 1 and NR band combination 1 belong to one capability information combination.
The terminal device may also determine second capability information of the terminal device, i.e. determine NR capability information of the terminal device. For example, the terminal device determines that the NR capability information of the terminal device includes capability information of NR band combination 1, capability information of NR band combination 2, capability information of NR band combination 3, and capability information of NR band combination 4, and as can be seen from table 1, the NE-DC capability information of the terminal device already includes capability information of NR band combination 1, capability information of NR band combination 2, and capability information of NR band combination 3, so that the NR capability information of the terminal device determined by the terminal device may no longer include capability information of NR band combination 1, capability information of NR band combination 2, and capability information of NR band combination 3, and then only capability information of NR band combination 4 may be included in the NR capability information determined by the terminal device. By the method, the probability of repeatedly reporting the capability information by the terminal equipment can be reduced, and transmission resources are saved.
Of course, the same is true for the LTE capability information of the terminal device. For example, the terminal device may further determine third capability information of the terminal device, where the third capability information is capability information of a frequency band combination of the terminal device under the second radio access technology, where the third capability information includes, for example, NR capability information of the terminal device, and the second radio access technology is NR, or the third capability information includes LTE capability information of the terminal device, and the second radio access technology is LTE. In the present embodiment, the first rat is NR, and the second rat is LTE. The terminal device may also determine third capability information of the terminal device, i.e. determine LTE capability information of the terminal device. Since the NE-DC capability information of the terminal device may include information of the LTE band combination and information of the NR band combination, which are partial capability information or all capability information in the LTE capability information of the terminal device, when determining the LTE capability information of the terminal device, the terminal device does not need to include the LTE capability information included in the NE-DC capability information, that is, the third capability information determined by the terminal device may not include the capability information of the band combination of the terminal device under LTE, which is already included in the first capability information, or simply, the third capability information determined by the terminal device may not include the capability information included in the first capability information, that is, the third capability information does not include the capability information in the first capability information, which means that the third capability information does not include the capability information included in the first capability information, Capability information of a band combination of the terminal device in the second radio access technology. For example, the first capability information includes capability information of a second band combination of the terminal device under LTE, and the third capability information does not include capability information of the second band combination of the terminal device under LTE, where the second band combination is not the same concept as the second band combination mentioned in the foregoing description of S51, S52, and S53 in another way. Alternatively, if the cases of S51, S52, and S53 are described in another way, it can be understood that the first capability information includes capability information of a third frequency band combination of the terminal device under LTE, and the third capability information does not include capability information of the third frequency band combination of the terminal device under LTE. The third band combination may comprise one or more band combinations.
For example, the terminal device determines that the LTE capability information of the terminal device includes capability information of LTE band combination 1, capability information of LTE band combination 2, capability information of LTE band combination 3, capability information of LTE band combination 4 and capability information of LTE band combination 5, it can be seen that in table 1, the capability information of LTE band combination 2, and the capability information of LTE band combination 3 are already included in the NE-DC capability information of the terminal device, so that in the LTE capability information of the terminal device determined by the terminal device, the capability information of LTE band combination 1, the capability information of LTE band combination 2 and the capability information of LTE band combination 3 may no longer be included, then in the LTE capability information determined by the terminal device, may include only the capability information of LTE band combination 4 and the capability information of LTE band combination 5. By the method, the probability of repeatedly reporting the capability information by the terminal equipment can be reduced, and transmission resources are saved.
The terminal device determines the first capability information, the second capability information and the third capability information of the terminal device, and the sequence of the three processes is not limited in the embodiment of the application. For example, the terminal device may determine the first capability information first and then determine the second capability information and the third capability information, and may determine the second capability information and the third capability information at the same time, or may determine the second capability information and the third capability information at different times without limiting which determination process of the capability information precedes, or the terminal device may determine the first capability information, the second capability information, and the third capability information at the same time, and so on.
After determining the first capability information and the second capability information, the terminal device may send the first capability information and the second capability information to the network device, so that the network device can obtain the capability information of the frequency band combination of the terminal device in the first radio access technology according to the first capability information and the second capability information. For example, the network device may obtain the capability information of the first frequency band combination of the terminal device in the first radio access technology, which is included in the first capability information, and obtain the capability information of the frequency band combination of the terminal device in the first radio access technology, which is included in the second capability information. Continuing with the example that the first capability information includes NE-DC capability information of the terminal device, the second capability information includes NR capability information of the terminal device, and the first radio access technology is NR. For example, if the network device acquires the capability information of the first band combination under NR of the terminal device included in the first capability information, for example, the capability information of the first band combination includes the capability information of NR band combination 1, the capability information of NR band combination 2, and the capability information of NR band combination 3, and the network device acquires the capability information of the band combination included in the second capability information, for example, the capability information of NR band combination 4, the network device can acquire the capability information of the band combination under NR of the terminal device, that is, the capability information of NR band combination 1, the capability information of NR band combination 2, the capability information of NR band combination 3, and the capability information of NR band combination 4.
The terminal device may send the first capability information and the second capability information to the network device through one message, for example, through a UE capability information message in S15 in the process shown in fig. 1, or may send the first capability information and the second capability information through two different messages, and if the first capability information and the second capability information are sent through two messages, the terminal device may send the first capability information and then send the second capability information, or send the second capability information and then send the first capability information, or send the first capability information and the second capability information at the same time.
Of course, if the terminal device also determines the third capability information, the third capability information may also be sent to the network device, and then the network device may also obtain the capability information of the frequency band combination of the terminal device in the second radio access technology after receiving the third capability information from the terminal device. Taking LTE as an example, the manner of obtaining the capability information of the frequency band combination of the terminal device under LTE by the network device is similar to the manner of obtaining the capability information of the frequency band combination of the terminal device under NR by the network device, for example, the network device may obtain the capability information of the second frequency band combination (or the third frequency band combination in another description manner) of the terminal device under second radio access technology, which is included in the first capability information, and obtain the capability information of the frequency band combination, which is included in the third capability information, of the terminal device under second radio access technology, which is not illustrated in detail.
For example, referring to fig. 6, an example of sending the first capability information, the second capability information, and the third capability information to the network device for the terminal device is shown, for example, the terminal device puts the first capability information, the second capability information, and the third capability information in one message, but sends them in three parts, for example, the message is a UE capability information message in S15. The first capability information, the second capability information and the third capability information are respectively located in 3 containers in the UE capability information message, wherein the third capability information is located in an LTE container, the second capability information is located in an NR container, and the first capability information is located in an MR-DC container. It can be seen in fig. 6 that the LTE contitainer includes a list of LTE band combinations of the terminal device, that is, a list of band combinations supported by the terminal device under LTE, the NR contitainer includes a list of NR band combinations of the terminal device, that is, a list of band combinations supported by the terminal device under NR, and the MR-DC contitainer includes a correspondence relationship between the band combinations supported by the terminal device under LTE and the band combinations supported by the terminal device under NR, or such a correspondence relationship may also be referred to as MR-DC band combinations, which is exemplified by NE-DC herein, and thus such a correspondence relationship may also be referred to as NE-DC band combinations. For example, the NE-DC band combinations supported by the terminal device include NE-DC band combination 1 to NE-DC band combination x, the band combinations supported by the terminal device under LTE include LTE band combination 1 to LTE band combination x, and the band combinations supported by the terminal device under NR include NR band combination 1 to NR band combination y, where NE-DC band combination 1 includes LTE band combination 1 and NR band combination 1, NE-DC band combination 2 includes LTE band combination 2 and NR band combination 2, and so on. Therefore, the NE-DC container includes the capability information of LTE band combination 1, the capability information of NR band combination 1, the capability information of LTE band combination 2, and the capability information of NR band combination 2, and the LTE container does not include the capability information of LTE band combination 1 and the capability information of LTE band combination 2, but includes only the capability information of LTE band combination 3 to the capability information of LTE band combination x, and similarly, the NR container does not include the capability information of NR band combination 1 and the capability information of NR band combination 2, but includes only the capability information of NR band combination 3 to the capability information of NR band combination y. By the technical scheme provided by the embodiment of the application, the probability that the terminal equipment repeatedly sends the same capability information is reduced, and system resources are saved.
The terminal device sends the first capability information, the second capability information, and the third capability information to the network device, and may send the first capability information, the second capability information, and the third capability information through one message, for example, through a UE capability information message in S15 in the procedure shown in fig. 1, or may send the first capability information, the second capability information, and the third capability information through different messages, for example, through three messages, or two types of the first capability information and the second capability information are sent through one message, and the remaining one type of the first capability information and the remaining one type of the second capability information are sent through another message, and if the three types of the first capability information and the remaining one type of the second capability information.
If the terminal device needs to send the capability information of the terminal device to the network device by using the method provided in the embodiment of the present application, as an optional implementation manner, the terminal device may send indication information to the network device, where the indication information is used to indicate that the second capability information sent by the terminal device does not include the capability information in the first capability information, and/or indicate that the third capability information sent by the terminal device does not include the capability information in the first capability information. Specifically, the indication information may indicate that the second capability information sent by the terminal device does not include the capability information in the first capability information, or indicate that the third capability information sent by the terminal device does not include the capability information in the first capability information, or indicate that the second capability information sent by the terminal device does not include the capability information in the first capability information, and indicate that the third capability information sent by the terminal device does not include the capability information in the first capability information. The indication information indicates that the second capability information sent by the terminal device does not include the capability information in the first capability information, that is, indicates that the second capability information does not include the capability information of the frequency band combination in the first capability information, or indicates that the second capability information sent by the terminal device does not include the capability information of the frequency band combination of the terminal device under the first radio access technology, which is included in the first capability information; the indication information indicates that the third capability information sent by the terminal device does not include the capability information in the first capability information, that is, indicates that the third capability information does not include the capability information of the frequency band combination in the first capability information, or indicates that the third capability information sent by the terminal device does not include the capability information of the frequency band combination of the terminal device in the second radio access technology, which is included in the first capability information. In this way, when the network device forwards the capability information to another network device, the other network device may determine, with the indication information, whether the first capability information includes a complete band combination supported by the terminal device, so that the network device may obtain the capability information of the band combination of the terminal device by using the method provided in the embodiment of the present application.
The indication information may be contained in the first capability information, the second capability information, or the third capability information, or for example, the terminal device sends the first capability information, the second capability information, and the third capability information through a message, where the message is, for example, the UE capability information message described in S15, and then the indication information may also be contained in the UE capability information message, but not contained in the first capability information, the second capability information, and the third capability information, or the terminal device may also send the indication information through a special message, and the location where the indication information is located is not limited in the embodiment of the present application.
As an optional implementation manner, the network device may also instruct the terminal device to transmit the capability information of the frequency band combination of the terminal device in a non-repeating manner provided in the embodiment of the present application. For example, the network device may transmit, to the terminal device, a request message for instructing the terminal device not to transmit the capability information of the band combination included in the first capability information when transmitting the capability information of the band combination of the terminal device in the first radio access technology, and/or instructing the terminal device not to transmit the capability information of the band combination included in the first capability information when transmitting the capability information of the band combination of the terminal device in the second radio access technology. Specifically, the request message may instruct the terminal device not to transmit the capability information of the band combination included in the first capability information when transmitting the capability information of the band combination of the terminal device in the first radio access technology, or instruct the terminal device not to transmit the capability information of the band combination included in the first capability information when transmitting the capability information of the band combination of the terminal device in the second radio access technology, or instruct the terminal device not to transmit the capability information of the band combination included in the first capability information when transmitting the capability information of the band combination of the terminal device in the first radio access technology, and instruct the terminal device not to transmit the capability information of the band combination included in the first capability information when transmitting the capability information of the band combination of the terminal device in the second radio access technology. The request message may be a message specifically used for instructing the terminal device to select the capability information of the frequency band combination of the terminal device in the non-repeating manner provided in the embodiment of the present application, or the request message may also be a multiplexed message, and the indication is performed by using an existing message, for example, the request message may also be used for requesting the capability information of the terminal device, and after receiving the request message, the terminal device may send the first capability information and the second capability information to the network device, for example, the request message is the UE capability request message described in S14.
After obtaining the capability information of the terminal device in the band combination under the first radio access technology, the network device may send the capability information of the terminal device in the band combination under the first radio access technology to other network devices. The other network device is, for example, an access network device or a core network device. For example, if the network device is an access network device in the process shown in fig. 1, after the access network device obtains the capability information of the band combination of the terminal device in the first radio access technology, since the core network device does not store the capability information of the terminal device in the first radio access technology, the access network device may send the capability information of the band combination of the terminal device in the first radio access technology to the core network device. In addition, the access network device may also send the capability information of the terminal device in the first radio access technology to other access network devices. In other words, after acquiring the capability information of the terminal device in the first radio access technology, the access network device may send the capability information of the terminal device in the first radio access technology to the other network device. For example, the access network device may add, in the second capability information, capability information of the first frequency band combination of the terminal device in the first radio access technology, which is included in the first capability information, to obtain updated second capability information, and the access network device may send the updated second capability information to other network devices. Thus, the updated second capability information comprises the capability information of the complete frequency band combination of the terminal device in the first radio access technology. In another mode, the access network device directly sends the received first capability information and the second capability information to other network devices without acquiring the capability information of the frequency band combination of the terminal device in the first radio access technology. The access network device can determine the mode to transmit by itself, or negotiate with the network device in advance, or can determine the mode according to the capability of other network devices. For example, the access network device may know the capabilities of other network devices in advance, where the capabilities of the network device mainly refer to whether the network device supports reading the first capability information, because the first capability information is mixed type capability information, such as MR capability information, and some network devices may not support reading such capability information. Alternatively, the network device does not support reading the first capability information, and it can also be understood that the network device does not support reading the MR-DC container. If the other network device supports reading the first capability information, the access network device may directly send the first capability information and the second capability information to the other network device, and the other network device obtains the capability information of the band combination of the terminal device in the first radio access technology by itself, in which the above description is referred to as the obtaining manner.
If the network device also obtains the third capability information, the network device may also send the capability information of the band combination of the terminal device in the second radio access technology to the other network device. When the network device sends the third capability information and the first capability information, the network device may obtain the capability information of the frequency band combination of the terminal device in the second radio access technology, and then send the capability information of the frequency band combination of the terminal device in the second radio access technology to other network devices. For example, the network device may add, in the third capability information, capability information of a second frequency band combination of the terminal device in the second radio access technology, which is included in the first capability information, to obtain updated third capability information, and the network device may send the updated third capability information to other network devices. Alternatively, the network device may also directly send the first capability information and the third capability information to other network devices, and the other network devices obtain the capability information of the frequency band combination of the terminal device in the second radio access technology by themselves, where the obtaining manner may refer to the above description. Whether the network device sends the third capability information and the second capability information or sends the capability information of the frequency band combination of the terminal device in the second radio access technology may also be determined according to the capabilities of other network devices, and similar contents may refer to the description in the previous paragraph and are not described in detail.
In the embodiment of the application, the terminal equipment only needs to send the same capability information once, and the repeated sending situation is reduced as much as possible, so that the system overhead is saved.
The following describes an apparatus for implementing the above method in the embodiment of the present application with reference to the drawings. Therefore, the above contents can be used in the subsequent embodiments, and the repeated contents are not repeated.

When the communication apparatus is a terminal device, fig. 11 shows a simplified structural diagram of the terminal device. For easy understanding and illustration, in fig. 11, the terminal device is exemplified by a mobile phone. As shown in fig. 11, the terminal device includes a processor, a memory, a radio frequency circuit, an antenna, and an input-output device.
