Description

Method and device for reporting terminal capability

Technical Field

The present application relates to the field of communications, and in particular, to a method and an apparatus for reporting terminal capability.

Background

In the process of registering a network, a terminal (also referred to as User Equipment (UE)) needs to report capabilities supported by the UE to network equipment (including a base station, core network equipment, and the like), so that the network equipment performs resource allocation for the UE according to the capabilities of the UE. The UE capability of the 5G is reported through a UE-new radio, NR-capability (cap availability), and the UE-NR-capability includes 5G capability parameters supported by the UE, where Carrier Aggregation (CA) capability supported by the UE is also reported through the UE-NR-capability.

Currently, a multi-subcarrier spacing (SCS) is defined in 5G, and a terminal may support multiple SCS, and in a 5G NR system, a defined UE-NR-capability reporting structure may cause that when a terminal reports capabilities, it needs to traverse various SCS combinations to report the capabilities of the terminal completely, which results in very complex configuration.

The interface name is only an example, and the embodiment of the present application is not particularly limited thereto. It should be understood that the embodiments of the present application are not limited to the communication system shown in fig. 1, and the names of the network elements shown in fig. 1 are only illustrated as an example herein, and are not intended to limit the network elements included in the architecture of the communication system to which the method of the present application is applicable. The functions of the various network elements or devices in the communication system are described in detail below:

the terminal, which may also be referred to as User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a user. For example, the terminals may include handheld devices, vehicle mounted devices, computing devices, Mobile Stations (MSs) or other processing devices coupled to wireless modems, etc. that have wireless connectivity, as well as mobile terminals that communicate with one or more core networks via an access network. Currently, the terminal may be: a mobile phone (mobile phone), a tablet computer, a notebook computer, a palm top computer, a Mobile Internet Device (MID), a wearable device, a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control (industrial control), a wireless terminal in self-driving (self-driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and the like. The terminal shown in fig. 1 is shown as a UE, which is only an example and is not limited to the terminal.

The radio access network may be AN Access Network (AN) shown in fig. 1, and provides a radio access service to the terminal. The access network device is a device for accessing the terminal to a wireless network in the communication system. The access network device is a node in a radio access network, which may also be referred to as a base station, and may also be referred to as a Radio Access Network (RAN) node (or device). Currently, some examples of access network devices are: a gbb, a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wifi) Access Point (AP), etc.

The data network, such as the Data Network (DN) shown in fig. 1, may be an internet (internet), an IP Multimedia Service (IMS) network, a local area network (i.e., a local network, such as a Mobile Edge Computing (MEC) network), and so on. The data network comprises an application server, and the application server provides service for the terminal by carrying out data transmission with the terminal.

The core network is used for accessing the terminal to a DN which can realize the service of the terminal. The following describes the functions of each network element in the core network:

the core network access and mobility management function network element may be configured to manage access control and mobility of the terminal, and in practical applications, the core network access and mobility management function network element includes a mobility management function in a Mobility Management Entity (MME) in a network framework in long term evolution (L TE), and is added with an access management function, and may be specifically responsible for registration, mobility management, tracking area update procedures, reachability detection, selection of a session management function network element, mobility state transition management, and the like of the terminal.

The session management functional network element may be configured to be responsible for session management (including establishment, modification, and release of a session) of the terminal, selection and reselection of a user plane functional network element, Internet Protocol (IP) address allocation, quality of service (QoS) control, and the like of the terminal. For example, in 5G, the session management function network element may be an SMF (session management function) network element, for example, as shown in fig. 1, in future communications, for example, in 6G, the session management function network element may still be an SMF network element, or may have another name, which is not limited in this application. When the session management function network element is an SMF network element, the SMF may provide an Nsmf service.

The policy control function network element can be used for taking charge of policy control decision, providing functions of service data flow and application detection, gating, QoS (quality of service) and flow-based charging control and the like. For example, in 5G, the policy control function network element may be a PCF (policy control function) network element, for example, as shown in fig. 1, and in future communication, for example, in 6G, the policy control function network element may still be a PCF network element, or have another name, which is not limited in this application. When the policy control function network element is a PCF network element, the PCF network element may provide an Npcf service.

The application function network element mainly has a function of interacting with a third generation partnership project (3 GPP) core network to provide services, so as to affect service flow routing, access network capability opening, policy control and the like. For example, in 5G, the application function network element may be an AF (application function) network element, for example, as shown in fig. 1, and in future communication, for example, in 6G, the application function network element may still be an AF network element, or may have another name, which is not limited in this application. When the application function network element is an AF network element, the AF network element may provide a Naf service.

The data management network element may be configured to manage subscription data of the terminal, registration information related to the terminal, and the like. For example, in 5G, the data management network element may be a unified data management network element (UDM), for example, as shown in fig. 1, and in future communications, for example, in 6G, the data management network element may still be a UDM network element or have another name, which is not limited in this application. When the data management network element is a UDM network element, the UDM network element may provide a numm service.

The network open function network element may be configured to enable the 3GPP to securely provide network service capabilities to AFs (e.g., Service Capability Servers (SCS), Application Servers (AS), etc.) of third parties. For example, in 5G, the network element with an open network function may be an NEF (network expansion) network element, for example, as shown in fig. 1, and in future communication, for example, in 6G, the network element with an open network function may still be an NEF network element or have another name, which is not limited in this application. When the network open function network element is a NEF, the NEF may provide an Nnef service to other network function network elements.

The unified description is made here, and the description is not repeated.

The communication system shown in fig. 1 is not intended to limit the communication system to which the embodiments of the present application can be applied. The communication system architecture shown in fig. 1 is a 5G system architecture, and optionally, the method of the embodiment of the present application is also applicable to various future communication systems, such as a 6G or other communication networks.

As is known, in the process of registering a network, a UE needs to report a capability supported by the UE to a network device (including a base station and a core network device), so that the network device performs resource allocation for the UE according to the capability of the UE. The UE capability of the 5G is reported through the UE-NR-capability, the UE-NR-capability comprises a 5G capability parameter supported by the UE, and the CA capability supported by the UE is also reported through the UE-NR-capability.

Currently, in a 5G NR system, a reporting structure of a defined UE-NR-capability includes a Feature set (Feature Sets), for example, as shown in an exemplary reporting structure of fig. 2, the Feature Sets include 4 lists of definitions of a downlink Feature set (Feature set downlink), an uplink Feature set (Feature set), a downlink carrier Feature set (component carrier, CC), and an uplink carrier Feature set (Feature set uplink percc), which are first-level structures in a Feature set structure, the Feature set downlink perceiv and the Feature set downlink perceiv uplink perck are first-level structures in the Feature set downlink, and the Feature set downlink perc and the Feature set downlink perceiv are second-level structures in the Feature set downlink structure, and each downlink carrier Feature set comprises a set of uplink parameters, and each downlink carrier Feature set (Feature set) includes one or more uplink parameters, and each downlink carrier Feature set (Feature set downlink carrier) includes a set of downlink multiple uplink perceiv downlink perceiv-downlink perceiv, and each downlink carrier Feature set includes one set of downlink parameters, and each downlink carrier Feature set of downlink carrier features set downlink carrier features, downlink carrier features set, downlink carrier features, downlink.

Wherein, the FeatureSetDownlinkPerCC includes a parameter (supported subcarriersspacingdd L) indicating a downlink subcarrier spacing supported by a carrier, and the featureuplinkpercc includes a parameter (supported subcarriersspacinu L) indicating an uplink subcarrier spacing supported by a carrier, at present, a plurality of subcarrier spacings (SCS) are defined in 5G, a terminal may support a plurality of SCS, each SCS corresponds to one featuretaildownlinlercc and featureuplinkpercc, and each featureupunlinkpercc and featureuplinkpercc can only correspond to one SCS, so that when a terminal reports capabilities, the terminal needs to report the capabilities of the terminal completely, and traverse various combinations, resulting in very complex configuration.

Based on this, the embodiment of the present application provides a method for reporting terminal capability, and provides a new reporting structure to solve the problem of complex capability information configuration in the prior art. The method for reporting the terminal capability provided in the embodiments of the present application is described in detail below with reference to specific embodiments.

The method for reporting the terminal capability provided by the embodiment of the application is suitable for a communication system shown in fig. 1. Referring to fig. 3, the specific process of the method includes:

step 301, the network device sends a terminal capability query message to the terminal.

Wherein the terminal capability query message is for requesting the terminal to transmit a capability of a specific Radio Access Technology (RAT).

The terminal capability query message may include one or more RATs (e.g., evolved public terrestrial radio access (E-UTRA), public terrestrial radio access (UTRA), New Radio (NR), E-UTRA-NR), which indicate that the terminal capability information under the RAT is requested. For example, when querying the terminal capability of 5G, the network device needs to specify the access technology as NR.

Step 302, the terminal sends terminal capability information to the network device, wherein the terminal capability information includes at least one first information and at least one second information; any one of the first information includes a frequency band capability parameter set supported by the terminal, any one of the second information includes a first carrier capability parameter set supported by the terminal, and the first carrier capability parameter set includes a set of subcarrier intervals of consecutive carriers supported by the terminal.

Illustratively, the first information and the second information may be actually as follows:

case a 1: the first information is a downlink feature set (FeatureSetDownlink), and the second information is the same downlink carrier feature set (sameffeaturesetdowdownlinkcc).

Case a 2: the first information is an uplink feature set (featurestapplink), and the second information is a same uplink carrier feature set (sameffeaturestapplinkcc).

In a specific manner, in the above case a1, the set of frequency band capability parameters supported by the terminal included in the first information is combined to be a set of downlink capability parameters of a frequency band supported by the terminal; and the first carrier capability parameter set supported by the terminal and included in the second information is a downlink capability parameter set of the carrier supported by the terminal.

For example, when the first set of carrier capability parameters is the set of downlink capability parameters of carriers supported by the terminal, the set of first carrier capability parameters may include a set of supported downlink subcarrier intervals (supported scsggroupd L), a supported downlink bandwidth (supported bandwidth d L), whether a downlink 90MHz bandwidth (channellw-90 MHz) is supported, a maximum multiple-In-multiple-Out (MIMO) layer number (maxNumberM IMO-L ayersPDSCH) supported by a physical downlink shared channel, and a supported downlink modulation order (supported modulation order L).

In another specific manner, in the case a2, the set of frequency band capability parameters supported by the terminal included in the first information is combined to be an uplink capability parameter set of a frequency band supported by the terminal; and the first carrier capability parameter set supported by the terminal and included in the second information is an uplink capability parameter set of the carrier supported by the terminal.

For example, when the first set of carrier capability parameters is the set of uplink capability parameters of carriers supported by the terminal, the set of first carrier capability parameters may include a set of supported uplink subcarrier intervals (supported scsggroupu L), a supported uplink bandwidth (supported bandwidth u L), whether an uplink 90MHz bandwidth is supported (channelBW-90MHz), a maximum MIMO layer number supported by a Physical Uplink Shared Channel (PUSCH) (MIMO-CB-PUSCH) in case of codebook-based precoding, a maximum MIMO layer number supported by a PUSCH (maxnumberbmimo-L eye rsnon CB-PUSCH) in case of non-codebook precoding, a supported uplink modulation order (supported modulanorderu L), an auxiliary uplink band, and a non-auxiliary uplink band concurrence (simultaneousTxSU L-non su L).

In practice, various subcarrier spacings are defined at 5G NR, for example, 15kHz/30kHz/60kHz/120kHz/240kHz and the like. Since the terminal may support more than one subcarrier interval, the configuration of the capability information may be simplified and the configuration complexity may be reduced by reporting the combination of the subcarrier intervals supported by the terminal, that is, by reporting the combination of the first set of carrier capability parameters in a manner of including the set of subcarrier intervals of consecutive carriers supported by the terminal.

Specifically, N pieces of the first information and one piece of the second information are associated, where the N pieces of the first information and one piece of the second information are associated such that each piece of the N pieces of the first information includes an identifier corresponding to the one piece of the second information, where the N pieces of the first information are one or more pieces of the at least one piece of the first information.

For example, when the first information and the second information meet the condition a1, the identifier corresponding to the one second information included in the N pieces of first information may be SameFeatureSetPerDownlinkCC-Id; when the first information and the second information conform to the condition a2, the identifier corresponding to the one piece of the second information included in the N pieces of first information may be samefeaturesetperapplinkcc-Id.

In the foregoing case, the N pieces of first information are associated with one piece of second information, that is, when the N pieces of first information are associated with the same piece of second information, the same piece of second information may be associated, and the associated piece of second information may report the subcarrier intervals supported by the terminal together, so that parameter combination may be implemented, and configuration information may be saved.

In one example, when the at least one piece of second information is a plurality of pieces of second information, the first carrier capability parameters in the first carrier capability parameter sets respectively contained in every two pieces of second information are not identical. For example, when the subcarrier spacing supported by the terminal is 15kHz/30kHz/60kHz/120kHz, the first carrier capability parameter in the first set of carrier capability parameters included in one of the second messages may include a set of 15kHz/30kHz, and the first carrier capability parameter in the first set of carrier capability parameters included in one of the second messages may include 60kHz/120 kHz. For another example, the subcarrier spacing sets included in the first set of carrier capability parameters are the same, while other parameters are not exactly the same. Or many other examples, which are not listed here.

Specifically, the terminal capability information may further include at least one third information, where any one of the third information includes a second carrier capability parameter set supported by the terminal, and the second carrier capability parameter set includes one subcarrier interval supported by the terminal.

In one implementation, in the scenario of the above case a1, the third information may be a downlink carrier characteristic set (featuretaillinkpercc), and accordingly, the second set of carrier capability parameters may be a set of downlink capability parameters of carriers supported by the terminal.

In another implementation, in the scenario of the above case a2, the third information may be an uplink carrier characteristic set (featureuplinkpercc), and accordingly, the second set of carrier capability parameters may be an uplink capability parameter set of carriers supported by the terminal, for example, the second set of carrier capability parameters may include a supported uplink subcarrier spacing (supported subcarrier spacing u L), a supported bandwidth width u L, a channlbw-90 mhz, a mimo-CB-PUSCH, a maxnumbermmimo-L anyersnon CB-PUSCH, a supported modulationderu L, and a simulta neouttx L-non su L.

Specifically, each of the M pieces of first information is associated with a group of the third information, where each of the M pieces of first information is associated with a group of the third information as an identifier corresponding to each of the group of the third information included in each of the M pieces of first information; the M pieces of first information are part of the at least one piece of first information.

For example, when there are a plurality of subcarrier intervals supported by the terminal, since each of the third information only includes one subcarrier interval, in this case, one of the M pieces of first information is associated with one set of the third information, so that the terminal capability information is completely reported.

Illustratively, when the first information and the third information meet the condition a1, a corresponding identifier of one of the third information may be FeatureSetDownlinkPerCC-Id; when the first information and the third information meet the condition a2, an identifier corresponding to one of the third information may be FeatureSetUplinkPerCC-Id.

By adopting the method for reporting the terminal capability provided by the embodiment of the application, the terminal receives the terminal capability query message from the network equipment and then sends the terminal capability information to the network equipment, wherein the terminal capability information comprises at least one first information and at least one second information; any one of the first information includes a frequency band capability parameter set supported by the terminal, any one of the second information includes a first carrier capability parameter set supported by the terminal, and the first carrier capability parameter set includes a set of subcarrier intervals of consecutive carriers supported by the terminal. In the method, the terminal capability information is reported by reporting the set of the subcarrier intervals of the continuous carriers supported by the terminal, so that the problem of ensuring the complete reporting by traversing the combination of various SCSs can be avoided, the configuration of the terminal capability information is simplified, and the configuration complexity is reduced.

Based on the above embodiments, in some specific examples, the terminal capability information reported by the terminal may be as follows:

in a specific example, FeatureSets carry a set of frequency band capability parameters and a set of carrier capability parameters (shown in fig. 2) supported by the UE, in this embodiment, for the downlink, in order to support parameter combination, a samefatersetserdownlinkcc may be defined in the FeatureSets by extending, in the FeatureSets, the samefatersetserdownlinkcc which is composed of several samefatersetsetpdown uplink ccs (i.e., the second information related to the present application), and each of the samefatersetsetpdown uplink ccs represents the same set of downlink parameters supported by a group of all consecutive carriers (i.e., the first set of carrier capability parameters supported by the terminal related to the present application).

Wherein, the samefeedperspedlinkcc is a newly added cell structure, and compared with the feaffetedlinekpercc (shown in detail in fig. 2), the first parameter of the samefeedperspedlinkcc is changed into an SCS set (subcarrierspacecinkset) of consecutive downlink carriers supported by the terminal, and the subcarrierspacekset can be defined as a string of bits, and each bit represents an SCS; other parameters in the structure are the same as defined in FeatureSetDownlinkPerCC.

In FeatureSetDownlink, an original cell FeatureSet L istPerDownlink CC is changed into an optional cell, and simultaneously, a selection (CHOICE) option of a newly added cell FeatureSetDownlink CC L ist is changed, and another CHOICE option is newly added, wherein the selection option is SameFeatureSetPerDownlink CC.

In summary, the downlink structure of the terminal capability information may be as shown in fig. 4.

In another specific example, FeatureSets carry a frequency band capability parameter set and a carrier capability parameter set (see fig. 2 in detail), in this embodiment, for uplink, to support parameter combination, a samefatersetseruplikcc may be defined in FeatureSets in an extended manner, where the samefatersetseruplikcc is composed of several samefatersetseruplikccs (i.e., second information related to this application), and each of the samefatersetseruplikccs represents the same uplink parameter set supported by a group of all continuous carriers (i.e., a first carrier capability parameter set supported by the terminal related to this application).

Wherein, the samefeedputuplinkcc is a newly added cell structure, and compared with the feaffetesuplinkcc (shown in detail in fig. 2), the first parameter of the samefeedputuplinkcc is changed into an SCS set (subcarriersspacinkset) of continuous uplink carriers supported by the terminal, and the subcarriersspacinkset is defined as a string of bits, and each bit represents an SCS; other parameters in the structure are the same as defined in FeatureSetUplinkPerCC.

In FeatureSetprimink, the original cell FeatureSet L istPeruplinkCC is changed into an optional cell, and simultaneously changed into a CHOICE option of the newly added cell FeatureSetpriminkCC L ist, and the newly added CHOICE option is SameFeatureSetpriminkCC.

In summary, the uplink structure of the terminal capability information may be as shown in fig. 5.

In another specific example, in this example, SameFeatureSetPerDownlink CC (i.e., the second information to which the present application relates) is directly defined in FeatureSetDownlink structure, and is in the same order as FeatureSet L istPerDownlink CC.

In another specific example, in this example, SameFeatureSetPeruplinkCC (i.e., the second information to which this application relates) is defined directly in FeatureSetUplink structure, in the same level as FeatureSet L istPeruplinkCC.

Based on the above embodiments, the effect of adopting the structure of the existing terminal capability information and adopting the structure of the terminal capability information proposed by the embodiments of the present application is described in a specific scenario. For example, a specific scenario is that the terminal only supports n1 frequency bands and one CA combination n1C (downlink continuous 2CC of n1 frequency bands), n1 downlink supports two SCS of 15kHz/30kHz, and each carrier of other downlink parameters is the same; the uplink does not support CA, and SCS supports 15kHz/30 kHz.

Specifically, fig. 8a shows a schematic situation of a terminal capability information structure (FeatureSets) reported when the existing terminal capability information is reported. Fig. 8b shows a schematic situation of a terminal capability information structure (FeatureSets) reported when the terminal capability information proposed in the embodiment of the present application is reported.

As can be seen from fig. 8a, each FeatureSetDownlinkPerCC and FeatureSetUplinkPerCC can only correspond to one SCS, and if the terminal capabilities are reported completely, various combinations need to be traversed, which results in very complex configuration. As can be seen from fig. 8b, compared with the reporting situation of fig. 8a, the configuration is simplified significantly. Therefore, by using the method for reporting terminal capability provided by the embodiment of the present application, the terminal capability information is reported by reporting the set of subcarrier intervals of continuous carriers supported by the terminal, so that the problem of traversing combinations of various SCS to ensure complete reporting can be avoided, the configuration of the terminal capability information is simplified, and the configuration complexity is reduced.

The terminal capability information further includes at least one third information, any one of the third information includes a second carrier capability parameter set supported by the terminal, and the second carrier capability parameter set includes a subcarrier interval supported by the terminal.

Specifically, each of the M pieces of first information is associated with a group of the third information, where each of the M pieces of first information is associated with a group of the third information as an identifier corresponding to each of the M pieces of first information included in the group of the third information; the M pieces of the first information are partial first information in the at least one piece of the first information.

Illustratively, when the at least one piece of the second information is a plurality of pieces of the second information, the first carrier capability parameters in the first carrier capability parameter sets respectively contained in every two pieces of the second information are not identical.

In one example, the set of frequency band capability parameters supported by the terminal included in the first information is a set of downlink capability parameters of a frequency band supported by the terminal; the first set of carrier capability parameters supported by the terminal included in the second information is a set of downlink capability parameters of carriers supported by the terminal.

Wherein N pieces of the first information are associated with one piece of the second information, where the N pieces of the first information and one piece of the second information are associated such that each piece of the N pieces of the first information includes an identifier corresponding to the one piece of the second information, where the N pieces of the first information are one or more pieces of the at least one piece of the first information.

Illustratively, the terminal capability information further includes at least one third information, any one of the third information includes a second carrier capability parameter set supported by the terminal, and the second carrier capability parameter set includes one subcarrier interval supported by the terminal.
