Detailed ways

The technical solutions in the present application will be described below with reference to the accompanying drawings.

The technical solution of the embodiment of the present application can be applied to various wireless communication systems or networks, for example, a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, and a wideband code. Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) System, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) communication system, the fifth generation of the future ( 5th Generation, 5G) system or New Radio (NR).

The terminal device in this embodiment of the present application may refer to an access terminal, a user equipment, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or User device. The terminal device may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), with wireless communication. Functional handheld devices, computing devices or other processing devices connected to wireless modems, in-vehicle devices, wearable devices, terminal devices in future 5G networks, or in the future evolution of the Public Land Mobile Network (PLMN) The terminal device and the like are not limited in this embodiment of the present application.

In the embodiment of the present application, the base station may be a base station (Base Transceiver Station, BTS) in a GSM or CDMA system, or may be a base station (NodeB, NB) in a WCDMA system, or may be an evolved base station in an LTE system (Evolutional NodeB). The eNB or the eNodeB) may also be a wireless controller in a Cloud Radio Access Network (CRAN) scenario, or the base station may be a relay station, an access point, an in-vehicle device, a wearable device, and a future 5G network. The base station in the base station or the base station in the future evolved PLMN network, for example, a new radio (NR) base station, is not limited in the embodiment of the present application. The base station may provide wireless cell signal coverage and serve the terminal device with one or more cells.

For ease of understanding, a number of terms referred to in this application are briefly introduced first.

Band: Generally speaking, it is a range of frequencies. For example, in the communication protocol, in order to make reference for the network operator and the equipment vendor, according to the actual situation of the spectrum resources of each country, the spectrum resources are divided into specific multiple ranges, and corresponding to a number, as a frequency band. For example, the actual physical spectrum range of LTE band 38 is 2570 MHz - 2620 MHz, and the physical spectrum range of LTE band 40 is 2300 MHz - 2400 MHz.

Carrier: The carrier frequency allocated to a terminal device can be used for communication frequency resources of signal transmission. The carrier can occupy a certain bandwidth and is located in the frequency band. Taking the LTE system as an example, the maximum carrier bandwidth of LTE is 20M, which can also be divided into 1.4M, 3M, 5M, or 10M. For example, the user camps on a cell with a cell ID of 0, and the cell corresponds to a carrier with a band of 38, a center frequency of 2585 M, and a bandwidth of 20 M.

This application is applicable to the scenario of carrier aggregation. FIG. 1 shows a carrier aggregation scenario of an embodiment of the present application. Carrier aggregation refers to the aggregation of two or more component carriers (CCs) to transmit data to achieve a larger transmission bandwidth. The terminal device can determine that up to several carriers can be used for uplink and downlink transmission according to the size of the capability. The CA function can support continuous or non-contiguous carrier aggregation and support intra-band or cross-band carrier aggregation. Further, the present application is also applicable to a dual connectivity scenario. The terminal device can use carrier aggregation for data transmission with a single base station. Alternatively, the terminal device may also use carrier aggregation for data transmission with multiple base stations. A typical implementation of the latter is to aggregate the carrier of one macro base station and the carriers of several micro base stations, and the micro base station needs to be connected with the macro base station through the backhaul link, and performs strict system time synchronization with the macro base station. .

FIG. 2 shows a dual connectivity scenario of an embodiment of the present application. Dual connectivity improves throughput by aggregating radio resources from different base stations. Generally, a dual connectivity scenario may include a primary base station and at least one secondary base station. The primary base station and the secondary base station can be connected through a communication interface. In the dual connectivity scenario, the primary base station and the secondary base station can jointly serve the terminal device. In other words, for the same session established by the terminal device and the core network, the primary base station and the secondary base station can simultaneously perform data transmission with the terminal device. In a possible scenario, the primary base station can be responsible for the control plane signaling flow and the user plane data transmission with the terminal device, and the secondary base station only needs to be responsible for the user plane data transmission with the terminal device. That is, the primary base station can establish a data resource bearer (DRB) and a signaling resource bearer (SRB) with the terminal device, and the secondary base station only needs to establish a DRB with the terminal device. Alternatively, in another possible scenario, each of the primary base station and the secondary base station may be responsible for control plane transmission and user plane data transmission with the terminal device. That is, the primary base station can establish a DRB and an SRB with the terminal device, and the secondary base station can also establish a DRB and an SRB with the terminal device.

The common feature of carrier aggregation and dual connectivity technology is that terminal devices transmit data through one or more base stations through multiple aggregated carriers. The difference is that the scheduling of multiple carriers in carrier aggregation is performed by one base station or the scheduler of the base station. In the dual connectivity scenario, the scheduler of the primary base station and the secondary base station respectively manage carriers on the respective base stations, so Coordinate with each other. Wherein, the function of the above scheduler may be a functional entity executed by a processor of the base station. Exemplarily, the dual connectivity scenario mentioned in this embodiment may be considered as a special case of a carrier aggregation scenario. In one example, the carrier aggregation scenario manages resources on lower layer protocols with lower user data transmission delays. The dual connectivity scenario manages resources on higher layer protocols and the user data transmission delay is higher. There are other differences between carrier aggregation and dual connectivity technologies, which are not repeated here.

FIG. 3 is a schematic structural diagram of an apparatus 300 for reporting capability information of a terminal device according to an embodiment of the present application. The device 300 can be a terminal device, or a device placed within the terminal device, such as a functional device or circuit board that does not include a housing. The apparatus 300 can be adapted for use in the application environment described in Figures 1, 2 or other portions of the embodiments of the present application. For ease of illustration, FIG. 3 shows only the main components of device 300. As shown in FIG. 3, the apparatus 300 includes a processor 301, a memory 302, a communication circuit 303, an antenna 304, and an input and output device 305. Further, the terminal device 300 may further include a bus system, and the processor 301, the memory 302, the communication circuit 303, the antenna 304, and the input/output device 305 are connected by a bus system. The processor 301 is mainly used for processing communication protocols and communication data, and controlling the entire device 300, executing software programs, and processing data of the software programs. The memory 302 is mainly used for storing software programs and data, for example, storing the above communication process. The data used. The communication circuit 303 is mainly used for converting a baseband signal and a radio frequency signal and processing the radio frequency signal. Communication circuit 303 is also referred to as a transceiver, radio frequency circuit, or radio frequency unit. The antenna 304 is mainly used for transmitting and receiving radio frequency signals in the form of electromagnetic waves. The input/output device 305, such as a touch screen, a display screen, a keyboard light, etc., is mainly used for receiving data input by a user and outputting data to the user. For example, the antenna 304 and the communication circuit 303 having the transceiving function may also be regarded as a transceiver of the device 300, or as a transceiver, a transceiver, or the like.

As described above, the terminal device needs to report the capability of the terminal device after accessing the wireless communication network, such as the base station, whether it is a carrier aggregation or a dual connectivity scenario. FIG. 4 shows a process interaction diagram of capability reporting by the terminal device. As shown in FIG. 4, in the S401 part, a base station in a wireless communication network may send a terminal device capability query message to a terminal device in its coverage area, or may also be referred to as a UE capability enquiry message. Indicates the ability of the terminal device to report itself. In the S402 part, after receiving the terminal device capability query message, the terminal device may send the terminal device capability information to the base station, or may be referred to as UE capability information, and carry the CA capability supported by the terminal device therein. Information, the CA capability information includes a CA band combination supported by the terminal device. It should be noted that the CA capability information in the embodiment of the present application can be applied to both a scenario of carrier aggregation and a dual connectivity scenario.

The CA band combination can refer to the combination of frequency band and carrier aggregation. In other words, the CA band combination can be used to indicate a carrier aggregation configuration corresponding to at least one frequency band. The CA configuration may refer to a combination of a CA operating band (s) and a CA bandwidth class (es). The CA operating band may refer to one or more operating bands used for carrier aggregation. The CA Bandwidth Classification may refer to a classification defined by the aggregated transmission bandwidth configuration and the maximum number of carriers for the one or more operating bands. The CA configuration can also be used to indicate other types of configuration information, such as supporting configuration information such as continuous CA in a frequency band or discontinuous CA in a frequency band. In some examples, the CA band combination can be used to indicate at least one of the following: the number of aggregated carriers, the maximum supported carrier bandwidth, the frequency band or combination of frequency bands, the intra-band intra-band continuous CA, and the discontinuous CA in the frequency band. Or inter-band CA. The maximum supported carrier bandwidth described above may refer to the maximum bandwidth of the supported aggregated carriers. Further, according to the support capability or the network specification of the terminal device, the cross-band CA can also be divided into two scenarios, such as spanning two frequency bands, spanning three frequency bands, or spanning four frequency bands. When the number of supported aggregate carriers is greater than 3, it also includes: cross-band CA and continuous CA combination in the frequency band, cross-band CA and discontinuous CA combination in the frequency band. For example, three carriers can be supported across band 1 and band 3 across the band CA and two of the carriers are supported for continuous CA within band 1. Or support 3 carriers in band 1 and band 3 across the band CA and support 2 of them in the band 1 discontinuous CA. Moreover, in some examples, the CA band combination can also indicate whether a certain band supports CA.

Depending on the type of terminal device, the types of CA band combinations supported by them vary. Typically, an end device can support a combination of CA bands supported by multiple carriers or countries. And the more frequency bands supported by the terminal device, the more types of CA band combinations that it may support. Therefore, the number of CA band combinations supported by the terminal device is considerable. For example, suppose the terminal device supports bands 1, 2, 3, 4, 5, 7, 8, 12, 17, 20, 38, 39, 40, 41 and various CA band combinations in these bands and across frequency bands. Table, its supported CA band combination can be more than 200 kinds.

As an example, for two complete bands of band 1 (downstream 2110 MHz - 2170 MHz) and band 3 (downstream 1805 MHz - 1880 MHz), the CA band combinations allowed by the protocol may include the following types of index indications:

CA_1C: Maximum 40M bandwidth, two carriers, continuous CA in band 1.

CA_1A-1A: Maximum 40M bandwidth, two carriers, non-continuous CA in band 1.

CA_3B: Maximum 10M bandwidth, continuous CA within band 3.

CA_3C: Maximum 40M bandwidth, two carriers, continuous CA in band 3.

CA_3A-3A: Maximum 40M bandwidth, two carriers, non-continuous CA in band 3.

CA_1A-3A: Maximum 40M bandwidth, two carriers, band 1 and band 3 cross-band CA.

CA_1A-1A-3A: Maximum 60M bandwidth, three carriers, band 1 and band 3 cross-band CA, where two carriers are discontinuous in band 1.

CA_1A-3A-3A: Maximum 60M bandwidth, three carriers, band 1 and band 3 cross-band CA, where two carriers are discontinuous in band 3.

CA_1A-3C:: Maximum 60M bandwidth, three carriers, band 1 and band 3 cross-band CA, where two carriers are consecutive in band 3.

CA_1A-1A-3C: Maximum 80M bandwidth, four carriers, band 1 and band 3 cross-band CA, where two carriers are discontinuous in band 1, and two carriers are continuous in band 3.

In addition, for the dual connectivity scenario, the above cross-band combinations will be divided into new combinations depending on the primary carrier. Each combination is a specific setting. The above embodiment is only an example, and includes a CA band combination corresponding to other frequency bands in actual application.

Generally, the frequency band that the network operator is allowed to operate is derived from the authorization of the country where the operator is located. Usually, an operator only has several frequency bands, and may only have a part of the bandwidth in a certain frequency band, not all the frequency bands. For example, for an operator, it only has four bands of 38, 39, 40, and 41 bands. And the operator can selectively own only part of the bandwidth of the band 40,41. Correspondingly, the CA band combination supported by the operator is also limited to the CA band combination corresponding to the four frequency bands.

In the related art, the terminal device may determine a frequency band supported by an operator or a country to which the currently camped wireless communication network belongs, and report only the CA band combination in the above frequency band. For example, the terminal device supports more than 200 combinations of CA bands. However, the current carrier only has the spectrum resources of the band 1 and the band 3, and the filtered terminal device only needs to report the combination of the CA bands involved in the band 1 and the band 3. The terminal device may determine, according to the system message sent by the base station, the operator or country to which the currently camped network belongs. For example, in an LTE system, the system message may be a Public Land Mobile Network (PLMN) identity list information in a system information block type.

The PLMN takes the form of a mobile country code (MCC) + mobile network code (MNC). The MCC is used to uniquely identify the country to which the mobile terminal user belongs. The MCC is usually represented by 3 digits. For example, China is 460. The MNC is used to identify the mobile network to which the mobile terminal user belongs. Generally, the same operator in a certain country can own one or more PLMNs, but different operators cannot share the same PLMN. That is, each PLMN must be assigned a unique MNC. For example, China Mobile uses 00, 02, 04, 07, China Unicom GSM system uses 01, 06, 09, China Telecom CDMA system uses 03, 05, Telecom 4G uses 11, and China Railcom uses 20.

For example, China Mobile's PLMN is 46000, 46002, 46004, 46007, and China Unicom's PLMN is 46001, 46006, 46009. The frequency bands supported may be different for different PLMNs owned by the same carrier. If there is only one carrier in a country, it can also determine the country to which the terminal device currently resides. Then, the CA band combination in the frequency band corresponding to the MCC supported by the terminal device is reported in the terminal device capability information.

However, the operator may only have a part of the bandwidth of the supported frequency band. For example, although the operator supports the band 1 and the band 3, it may only have the 20 M continuous bandwidth of the band 1 and the 20 M continuous bandwidth of the band 3, and the network is configured according to the 20 M bandwidth. . In the foregoing CA band combination, only the CA band combination of CA_1A-3A can be supported in the communication, and the reporting of the remaining CA band combinations is redundant. Or, the operator may be limited by the specifications of the network. For example, if the current network does not support carriers of more than 3 carriers, the reporting of the combination of CA bands supporting more than three carrier aggregations is redundant. In other words, it is not necessary to report the various aggregation scenarios supported by each frequency band.

In contrast to the above analysis, in order to avoid the terminal device reporting excessive CA band combination, resources are wasted. More importantly, in order to avoid the terminal device's inability to parse the terminal device capability information due to excessive volume of the terminal device capability information, and causing compatibility problems. The embodiments of the present application are directed to a method for reporting terminal device capability information and assisting in reporting terminal device capability information, which can simplify the number of CA band combinations in the reported terminal device capability information, thereby saving air interface resources and also enhancing Network compatibility.

FIG. 5 is a schematic diagram of interaction of a method 500 for reporting terminal device capability information according to an embodiment of the present application. The method 500 can be performed by a terminal device and a base station. The method 500 can be applied to a carrier aggregation scenario or a dual connectivity scenario. The method 500 shows a process in which the terminal device reports the terminal device capability information and the base station assists in reporting the terminal device capability information. As shown in FIG. 5, method 500 includes:

S501. The wireless communication network sends a communication message to the terminal device, and accordingly, the terminal device receives the communication message from the wireless communication network. The wireless communication network may optionally include an access network and a core network. The access network includes a base station, which is used to implement coverage of a cell signal and serves the terminal device by using a cell and a carrier. For details, refer to the foregoing. The core network includes a core network device. The core network device may include, for example, a user plane function (UPF) entity, an access and Mobility Management function (AMF), and a session management function (SMF). entity.

The communication message received by the terminal device may specifically come from a base station in the wireless communication network. The communication message is generated by the base station or is a communication message received by the base station from the core network and forwarded by the base station. Optionally, if the macro base station and the micro base station cooperate to transmit in a carrier aggregation scenario, the base station may be a macro base station. In a dual connectivity scenario, the base station may be a primary base station or a secondary base station.

In the case that the communication message is from an access network, such as the base station, the communication message may be radio resource control (RRC) layer signaling. For example, the communication message can be a system message or a terminal device capability query message. In case the communication message is from the core network, the communication message may be non-access stratum (NAS) signaling.

S502. The terminal device determines, according to the communication message, a first set of CA frequency bands supported by the wireless communication network. The first CA band combination set may include a CA band combination actually supported by the current wireless communication network. For example, for the same carrier, depending on the policies deployed in different regions, the networks in different regions actually support different frequency bands and CA band combinations.

Optionally, the terminal device may determine the first set of CA frequency bands in two ways. In the first mode, the communication message may include the first set of CA band combinations. The terminal device directly acquires the first CA frequency band combination set by using the communication message.
