Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] In Long Term Evolution-Advanced (LTE-A), when a terminal device supports multiple carrier aggregation (CA) combinations, if the number of supported CA combinations exceeds the maximum CA combination limit of 128 that the network device can query, there is a problem that the maximum number of CA combinations currently supported by the network cannot be reported to the network device, thus affecting the data transmission rate between the terminal device and the network device. Carrier aggregation refers to combining two or more component carriers (CCs) together to support greater transmission bandwidth.

[0003] Therefore, improving the data transmission rate between terminal devices and network devices has become an urgent problem to be solved. Summary of the Invention

[0004] This application provides a communication method and related apparatus, which is beneficial to improving the data transmission rate between terminal devices and network devices.

[0005] In a first aspect, embodiments of this application provide a communication method, which is described from the perspective of a terminal device or a device such as a chip or processor in the terminal device, and the method includes:

[0006] Receive capability information reporting request messages from network devices;

[0007] Send the first frequency band information and the first carrier aggregation (CA) combination information to the network device;

[0008] The first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first public land mobile network PLMN or the first mobile network number MNC; the first PLMN is the PLMN of the cell selected by the terminal device, and the first MNC is the MNC corresponding to the first PLMN.

[0009] In this embodiment of the application, after receiving a capability information reporting request message from a network device, the terminal device can report the first frequency band information and the first CA combination information supported by the terminal device under the network corresponding to the USIM card to the network device. This is beneficial for the network device to obtain the maximum CA combination information that both can support based on the frequency band information and CA combination information reported by the terminal device, thereby improving the data transmission rate between the terminal device and the network device.

[0010] In an optional implementation, before receiving a capability information reporting request message from a network device, the method further includes: determining whether a first PLMN or a first MNC exists in first information; the first information stores frequency band information and CA combination information supported by the terminal device under different communication networks corresponding to different PLMNs or different MNCs; in response to the existence of the first PLMN or the first MNC in the first information, obtaining the first frequency band information and the first CA combination information from the first information.

[0011] In this embodiment, if the terminal device determines that the first PLMN or the first MNC exists in the first information, it can filter the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first PLMN or the first MNC from the first information. This helps to avoid the reporting of invalid frequency band information and invalid CA combination information, thereby increasing the probability that the terminal device reports the maximum CA combination information supported under the current network, and further improving the data transmission rate between the terminal device and the network device.

[0012] In one optional implementation, after obtaining the first frequency band information and the first CA combination information from the first information, the method further includes: storing the obtained first frequency band information and CA combination information in a first container;

[0013] Sending first frequency band information and first carrier aggregation (CA) combination information to a network device includes: sending the first frequency band information and first CA combination information in a first container to the network device.

[0014] In this embodiment, the terminal device can store the first frequency band information and the first CA combination information obtained from the first information in a first container. In this way, after receiving a capability information reporting request message from the network device, the terminal device does not need to obtain the first frequency band information and the first CA combination information, but can send the first frequency band information and the first CA combination information in the first container to the network device. This can improve the rate at which the terminal device reports the first frequency band information and the CA combination information and reduce latency.

[0015] In an optional implementation, the method further includes: in response to the first PLMN or the first MNC not existing in the first information, after receiving a capability information reporting request message from the network device, sequentially sending the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capabilities of the frequency band information and CA combination information supported by the terminal device, until the maximum value of the frequency band information and CA combination information queried by the network device is reached.

[0016] In this embodiment, the terminal device reports the frequency band information and CA combination information it supports to the network device in descending order of the capabilities of the frequency band information and CA combination information it supports. This can increase the probability that the terminal device reports the maximum CA combination information supported under the current network, thereby improving the data transmission rate between the terminal device and the network device.

[0017] In one optional implementation, in response to the capability information reporting request message not including the frequency band to be reported, the step of sending the first frequency band information and the first CA combination information to the network device is performed; or, the step of sending the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capability of the frequency band information and CA combination information supported by the terminal device is performed until the maximum value of the frequency band information and CA combination information queried by the network device is reached.

[0018] In an optional implementation, the method further includes: in response to the capability information reporting request message including a frequency band to be reported, sending second CA combination information to the network device; the second CA combination information is determined by the terminal device based on the frequency band to be reported.

[0019] In an optional implementation, the method further includes: determining first information based on the frequency band information and CA combination information supported by the terminal device in the communication networks corresponding to multiple different PLMNs or different MNCs; and storing the first information.

[0020] In this embodiment, the terminal device can determine the first information and store the first information. This is beneficial for the terminal device to directly obtain the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first PLMN or the first MNC from the first information when it determines that the first PLMN or the first MNC exists in the first information.

[0021] In an optional implementation, the method further includes: if the number of frequency band information and CA combination information sent to the network device does not reach the maximum value of frequency band information and CA combination information that the network device can query, then the third frequency band information and third CA combination information are sent to the network device in descending order of their capabilities, until the maximum value of frequency band information and CA combination information that the network device can query is reached; wherein, the third frequency band information and third CA combination information are frequency band information and CA combination information other than the first frequency band information and first CA combination information supported by the terminal device.

[0022] Secondly, embodiments of this application provide a communication method, which is described from the perspective of a network device or a device such as a chip or processor in the network device. The method includes:

[0023] Send a capability information reporting request message to the terminal device;

[0024] Receive first frequency band information and first carrier aggregation (CA) combination information from the terminal device;

[0025] The first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first public land mobile network PLMN or the first mobile network number MNC;

[0026] The first PLMN is the PLMN of the cell selected by the terminal device, and the first MNC is the MNC corresponding to the first PLMN.

[0027] In this embodiment, by receiving the segment information and CA combination information supported under the current network reported by the terminal device, the network device can obtain the maximum CA combination information that the two can support, thereby improving the data transmission rate between the terminal device and the network device.

[0028] In an optional implementation, the method further includes: sequentially receiving frequency band information and CA combination information supported by the terminal device; the frequency band information and CA combination information supported by the terminal device are sorted in descending order of capability.

[0029] In this embodiment, since the frequency band information and CA combination information supported by the terminal device are sorted in descending order of capability, the network device can obtain the maximum CA combination information supported by both by receiving the frequency band information and CA combination information supported by the terminal device in sequence, which is beneficial to improving the data transmission rate between the terminal device and the network device.

[0030] In one optional implementation, if the capability information reporting request message does not include the frequency band to be reported, the step of receiving the first frequency band information and the first CA combination information from the terminal device is performed; or, the step of sequentially receiving the frequency band information and CA combination information supported by the terminal device is performed.

[0031] In an optional implementation, the method further includes: receiving second CA combination information from a terminal device when the capability information reporting request message includes a frequency band to be reported; the second CA combination information is determined by the terminal device based on the frequency band to be reported.

[0032] In an optional implementation, the method further includes: if the number of frequency band information and CA combination information received from the terminal device in the first frequency band information and the first CA combination information does not reach the maximum value of frequency band information and CA combination information queried by the network device, then the third frequency band information and the third CA combination information received from the terminal device are received sequentially; wherein, the third frequency band information and the third CA combination information are frequency band information and CA combination information other than the first frequency band information and the first CA combination information supported by the terminal device; the third frequency band information and the third CA combination information have been sorted in descending order of capability.

[0060] In this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document indicates that the preceding and following related objects have an "or" relationship.

[0061] "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or multiple items.

[0065] Please see Figure 1 , Figure 1This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Figure 1 The device configurations shown are for illustrative purposes and do not constitute a limitation on the embodiments of this application. Figure 1 As shown, the communication system may include at least one terminal device (shown as an example including terminal device 101 in the figure) and at least one network device (shown as an example including network device 102 in the figure).

[0066] In this application, the terminal equipment is a device that supports LTE-A and standard evolution, and can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), access terminal equipment, vehicle-mounted terminal equipment, industrial control terminal equipment, UE unit, UE station, mobile station, mobile station, remote station, remote terminal equipment, mobile device, UE terminal equipment, wireless communication equipment, smart terminal equipment, UE agent, or UE device, etc. The terminal equipment can be fixed or mobile.

[0067] Optionally, the terminal device can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can be deployed on water (such as ships); and it can also be deployed in the air (such as airplanes, balloons and satellites).

[0068] It should be noted that the terminal device can support at least one wireless communication technology, such as Long-Term Evolution (LTE), New Radio (NR), 6G, or next-generation wireless communication technology. For example, terminal devices can be mobile phones, tablets, desktop computers, laptops, all-in-one computers, in-vehicle terminals, virtual reality (VR) terminal devices, augmented reality (AR) terminal devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, wearable devices, terminal devices in next-generation communication systems such as NR networks, terminal devices in future mobile communication networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc.

[0069] Furthermore, the terminal device may also include a device with transceiver functions, such as a chip system. The chip system may include chips, but may also include other discrete components.

[0070] In this application, the network device can be a device used for communication with terminal devices, responsible for radio resource management (RRM), quality of service (QoS) management, data compression and encryption, data transmission and reception, etc. on the air interface side. The network device can be a base station (BS) in a communication system or a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, base stations (BTS) in Global System for Mobile Communication (GSM) or Code Division Multiple Access (CDMA) communication systems, node B (NB) in Wideband Code Division Multiple Access (WCDMA) communication systems, evolved node B (eNB or eNodeB) in LTE communication systems, next generation evolved node B (ng-eNB) in NR communication systems, next generation node B (gNB) in NR communication systems, master node (MN) in dual-link architecture, and secondary node (SN) in dual-link architecture are not specifically limited in this regard.

[0071] Optionally, network equipment can also be other equipment in the core network (CN), such as access and mobility management function (AMF), user plan function (UPF), etc.; it can also be access point (AP) in wireless local area network (WLAN), relay station, communication equipment in future evolved PLMN network, communication equipment in non-terrestrial network (NTN) network, etc.

[0072] Optionally, the network device may include means for providing wireless communication capabilities to terminal devices, such as a chip system. For example, a chip system may include a chip, and may also include other discrete components.

[0073] It should be noted that in some network deployments, a network device can be a standalone node to implement all the functions of the aforementioned base station. This can include centralized units (CUs) and distributed units (DUs), such as gNB-CU and gNB-DU; it can also include active antenna units (AAUs). The CU can implement some of the network device's functions, and the DU can also implement some of its functions. For example, the CU is responsible for handling non-real-time protocols and services, implementing the functions of the Radio Resource Control (RRC) layer, Service Data Adaptation Protocol (SDAP) layer, and Packet Data Convergence Protocol (PDCP) layer. The DU is responsible for handling physical layer protocols and real-time services, implementing the functions of the Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and Physical (PHY) layer. Additionally, the AAU can implement some physical layer processing functions, radio frequency processing, and related functions of the active antenna. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this network deployment, higher-layer signaling (such as RRC layer signaling) can be considered to be sent by the DU, or jointly by the DU and AAU. It is understood that network devices can include at least one of CU, DU, and AAU. Furthermore, the CU can be classified as a network device in the radio access network (RAN), or it can be classified as a network device in the core network; no specific limitation is made in this regard.

[0074] Optionally, the network device may have mobility characteristics; for example, the network device may be a mobile device. Optionally, the network device may be a satellite or a balloon station. For example, the satellite may be a low Earth orbit (LEO) satellite, a medium Earth orbit (MEO) satellite, a geostationary earthorbit (GEO) satellite, or a high elliptical orbit (HEO) satellite. Optionally, the network device may also be a base station located on land, water, or other similar locations. This network device includes network device 102.

[0075] First, some concepts involved in the embodiments of this application will be briefly explained.

[0076] 1. Carrier aggregation (CA)

[0077] CA (Carrier A) aggregates two or more component carriers (CCs) together to support a larger transmission bandwidth (up to 100MHz). Each CC has a maximum bandwidth of 20MHz.

[0078] Optionally, CA can support aggregation between different CCs.

[0079] 2. Public Land Mobile Network (PLMN)

[0080] In a particular country or region, a specific type of cellular mobile communication network operated by a particular operator is called a PLMN. A PLMN is a network established and operated by the government or a government-approved operator to provide terrestrial mobile communication services to the public. A PLMN can interconnect with other communication networks such as the Public Switched Telephone Network (PSTN) to form a communication network on a regional or national scale.

[0081] 3. Mobile network code (MNC)

[0082] MNC is used to identify the mobile communication network to which a mobile user belongs, and consists of 2 to 3 digits.

[0083] Within the same country, if there are multiple PLMNs (generally, one operator corresponds to one PLMN in a country), they can be distinguished by their MNC. For example, China Mobile's MNC is 00 or 02; China Unicom's MNC is 01, and so on.

[0084] 4. Universal Subscriber Identity Module (USIM) Card

[0085] A USIM card, also known as an upgraded SIM card, is a component of the 3rd generation (3G) network of the Universal Mobile Telecommunication System (UMTS). Compared to a SIM card, a USIM card not only supports more applications but also features upgraded security algorithms and adds card authentication capabilities to the network.

[0086] 5. International Mobile Subscriber Identification Number (IMSI)

[0087] The IMSI is an identifier that distinguishes mobile users. It is stored in the SIM card or USIM card and can be used to identify valid information about mobile users. The total length of the IMSI does not exceed 15 digits, and it also uses the numbers 0 to 9. It includes a 3-digit mobile country code (MCC) and a 2-3 digit MNC.

[0088] The resources of the MCC (Mobile Control Center) are allocated and managed uniformly by the ITU (International Telecommunication Union) and can be used to identify the country to which a mobile user belongs. For example, China's MCC is 460.

[0089] Optionally, the relevant explanation of MNC can be found in the description above, and will not be repeated here.

[0090] The communication method provided in the embodiments of this application will be described in detail below.

[0091] Please see Figure 2 , Figure 2 This is a flowchart illustrating a communication method provided in an embodiment of this application. For example... Figure 2 As shown, the communication method may include, but is not limited to, the following steps:

[0092] S201. The network device sends a capability information reporting request message to the terminal device, and the terminal device receives the capability information reporting request message from the network device.

[0093] Optionally, the capability information reporting request message is a capability information query message (UECAPABILITYENQUIRY).

[0094] S202. The terminal device sends the first frequency band information and the first carrier aggregation CA combination information to the network device. Correspondingly, the network device receives the first frequency band information and the first carrier aggregation CA combination information from the terminal device. The first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first public land mobile network PLMN or the first mobile network number MNC. The first PLMN is the PLMN of the cell selected by the terminal device, and the first MNC is the MNC corresponding to the first PLMN.

[0095] For example, assuming that the terminal device supports frequency band information 1 to frequency band information 50 and CA combination information 1 to CA combination information 50 respectively in the communication network corresponding to the first PLMN or the first MNC, the terminal device can send frequency band information 1 to frequency band information 50 and CA combination information 1 to CA combination information 50 to the network device.

[0096] Optionally, the first PLMN can also be called the Home Public Land Mobile Network (HPLMN).

[0097] In one alternative implementation, the terminal device may obtain the first PLMN based on the system information block 1 (SIB1) message.

[0098] Optionally, the terminal device may determine the first PLMN and the first MNC based on the corresponding IMSI of the USIM card in the terminal device.

[0099] In one optional implementation, if the number of frequency band information and CA combination information sent to the network device does not reach the maximum value for frequency band information and CA combination information queried by the network device, then the third frequency band information and third CA combination information can be sent to the network device sequentially in descending order of capability, until the maximum value for frequency band information and CA combination information queried by the network device is reached. Correspondingly, the network device sequentially receives the third frequency band information and third CA combination information from the terminal device, which has been sorted in descending order of capability. Here, the third frequency band information and third CA combination information are frequency band information and CA combination information other than the first frequency band information and first CA combination information supported by the terminal device.

[0100] Optionally, in scenarios where network devices query terminal device capability information using 3GPP protocol R10 and earlier versions, the maximum value for querying frequency band information and CA combination information is 128.

[0101] For example, suppose the maximum number of frequency band information and CA combination information that a network device can query is 128, and the terminal device sends 100 frequency band information and CA combination information to the network device in the first frequency band information and the first CA combination information. In this case, since the number of CA combination information (100) in the first frequency band information and the first CA combination information does not reach the maximum number of frequency band information and CA combination information that the network device can query (128), the terminal device can send another 128-100=28 third frequency band information and third CA combination information to the network device in descending order of the capabilities of the third frequency band information and the third CA combination information.

[0102] In this embodiment of the application, since the spectrum resources under different networks (or operators) are limited and relatively fixed, after receiving the capability information reporting request message from the network device, the terminal device can combine the characteristic that the spectrum resources under different networks are limited and relatively fixed, and report the frequency band information and CA combination information supported by the terminal device under the current network to the network device. This is beneficial for the network device to obtain the maximum CA combination information that both can support, and thus helps to improve the data transmission rate between the terminal device and the network device.

[0103] Specifically, using the embodiments of this application, when the number of frequency band information and CA combination information supported by the terminal device under the current network is greater than the maximum value of frequency band information and CA combination information queried by the network device, by avoiding the reporting of invalid frequency band information and invalid CA combination information, the probability of the terminal device reporting the maximum CA combination information supported under the current network can be increased. This is beneficial for the network device to obtain the maximum CA combination information that both can support, thereby improving the data transmission rate between the terminal device and the network device. When the number of frequency band information and CA combination information supported by the terminal device under the current network is less than or equal to the maximum value of frequency band information and CA combination information queried by the network device, the network device can obtain the maximum CA combination information supported by the terminal device under the current network. Therefore, the network device's configuration of the terminal device and the network device can reach the maximum capabilities of the terminal device and the network device, thereby improving the data transmission rate between the terminal device and the network device.

[0104] Please see Figure 3 , Figure 3This is a flowchart illustrating another communication method provided in an embodiment of this application. Figure 2 The difference in the communication methods shown is that, Figure 3 The communication method described also illustrates how the terminal device determines whether the first PLMN or the first MNC exists in the first information. For example... Figure 3 As shown, the communication method may include, but is not limited to, the following steps:

[0105] S301. The terminal device determines whether the first PLMN or the first MNC exists in the first information. The first PLMN is the PLMN of the cell selected by the terminal device, and the first MNC is the MNC corresponding to the first PLMN. If yes, then execute steps S302a to S304; if no, then execute step S302b.

[0106] The first information stores the frequency band information and CA combination information supported by the terminal device under different PLMNs or different MNCs in their respective communication networks.

[0107] Optionally, the relevant descriptions of the first PLMN and the first MNC can be found in the relevant descriptions in the aforementioned step S201, and will not be repeated here.

[0108] In an optional implementation, before step S301, the terminal device may further determine the first information based on the frequency band information and CA combination information supported by the communication networks corresponding to different PLMNs or different MNCs; and store the first information.

[0109] Optionally, the terminal device can distinguish specific operators or countries locally based on different PLMNs or different MNCs, and store the frequency band information and CA combination and information supported by the terminal device under the corresponding communication network of that operator or country.

[0110] S302a. The terminal device obtains the first frequency band information and the first CA combination information from the first information. The first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first PLMN or the first MNC.

[0111] In other words, the terminal device can execute step S302a in response to the existence of the first PLMN or the first MNC in the first information.

[0112] For example, suppose the first information includes the frequency band information and CA combination information supported by the terminal device under the network with MNC 00 (corresponding to China Mobile), and the frequency band information and CA combination information supported by the terminal device under the network with MNC 01 (corresponding to China Unicom). If the first MNC is 00, that is, the MNC in the IMSI corresponding to the USIM card in the terminal device is 00, then the terminal device can determine that the first MNC exists in the first information. In this case, the terminal device can obtain the first frequency band information and the first CA combination information from the first information. At this time, the first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the network corresponding to MNC 00 (i.e., China Mobile).

[0113] In one optional implementation, after step S302a, the terminal device may further store the acquired first frequency band information and first CA combination information in a first container.

[0114] S303. The terminal device receives a capability information reporting request message from the network device. Correspondingly, the network device sends a capability information reporting request message to the terminal device.

[0115] S304. The terminal device sends the first frequency band information and the first CA combination information to the network device, and the network device receives the first frequency band information and the first CA combination information from the terminal device.

[0116] In an optional implementation, the relevant description of step S304 can be found in the description of step S202 above, and will not be repeated here.

[0117] In an optional implementation, after step S302a, if the terminal device stores the acquired first frequency band information and first CA combination information in a first container, then after receiving a capability information reporting request message from the network device, the terminal device can send the first frequency band information and first CA combination information from the first container to the network device. This avoids the problem of the terminal device failing to report the maximum CA combination information supported under the current network in a timely manner due to limitations in the network device's query method.

[0118] S302b: The terminal device receives a capability information reporting request message from the network device, and in turn, the network device sends a capability information reporting request message to the terminal device.

[0119] S305. The terminal device sends the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capability of the terminal device to support frequency band information and CA combination information, until the maximum value of the frequency band information and CA combination information queried by the network device is reached. Correspondingly, the network device receives the frequency band information and CA combination information supported by the terminal device in sequence.

[0120] Among them, the frequency band information and CA combination information supported by the terminal devices received by the network devices in sequence have been sorted in descending order of capability.

[0121] In other words, in response to the fact that the first PLMN or the first MNC does not exist in the first information, after receiving the capability information reporting request message from the network device, the terminal device may send the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capability of the frequency band information and CA combination information supported by the terminal device, until the maximum value of the frequency band information and CA combination information queried by the network device is reached.

[0122] For example, suppose the maximum value of frequency band information and CA combination information queried by the network device is 128. The first information includes the frequency band information and CA combination information supported by the terminal device under the network with MNC 00 (corresponding to China Mobile), and the frequency band information and CA combination information supported by the terminal device under the network with MNC 01 (corresponding to China Unicom). If the first MNC is 11 (corresponding to China Telecom), that is, the MNC in the IMSI corresponding to the USIM card in the terminal device is 11, then the terminal device can determine that the first MNC does not exist in the first information. In this case, after receiving the capability information reporting request message from the network device, the terminal device can send 128 pieces of frequency band information and CA combination information supported by the terminal device to the network device in descending order of capability, according to the frequency band information and CA combination information supported by the terminal device.

[0123] In this embodiment, if the terminal device determines that the first PLMN or the first MNC does not exist in the first information, it may, in response to a capability information reporting request message from the network device, sequentially report the frequency band information and CA combination information supported by the terminal device to the network device in descending order of their supported capabilities. This increases the probability that the terminal device will report the maximum CA combination information supported under the current network, thereby helping the network device obtain the maximum CA combination information that both can support, and ultimately improving the data transmission rate between the terminal device and the network device.

[0124] Please see Figure 4Example 4 is a flowchart illustrating another communication method provided in an embodiment of this application. Figure 3 The difference in the communication methods shown is that, Figure 4 In the communication method shown, the terminal device further determines whether the received capability information reporting request message includes the frequency band to be reported. For example... Figure 4 As shown, the communication method may include, but is not limited to, the following steps:

[0125] S401. The terminal device determines the first information based on the frequency band information and CA combination information supported by the communication networks corresponding to different PLMNs or different MNCs.

[0126] S402, The terminal device stores the first information.

[0127] S403. The terminal device determines whether the first PLMN or the first MNC exists in the first information. The first PLMN is the PLMN of the cell selected by the terminal device, and the first MNC is the MNC corresponding to the first PLMN. If yes, then execute step S404a; otherwise, execute step S404b.

[0128] S404a. The terminal device obtains the first frequency band information and the first CA combination information from the first information. The first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first PLMN or the first MNC.

[0129] In an optional implementation, the relevant descriptions of steps S403 and S404a can be found in the descriptions of steps S301 and S302a above, and will not be repeated here.

[0130] In one alternative implementation, steps S405 to S407b may also be performed after step S404a.

[0131] S405. The terminal device receives a capability information reporting request message from the network device. In response, the network device sends a capability information reporting request message to the terminal device.

[0132] S406. The terminal device determines whether the capability information reporting request message includes the frequency band to be reported; if yes, proceed to step S407a; if no, proceed to step S407b.

[0133] Optionally, whether the capability information reporting request message includes the frequency band to be reported can be determined by the terminal device based on the elements in the capability information reporting request message. For example, the capability information reporting request message includes Universal Terrestrial Radio Access (UTRA), Evolved-UTMS Terrestrial Radio Access (EUTRA), GSM EDGE Radio Access Network-CS (GERAN-CS) in the circuit-switched domain (CS), GSM EDGE Radio Access Network-PS (GERAN-PS) in the packet-switched domain (PS), Code Division Multiple Access 2000-1x Radio Transfers Technology (CDMA2000-1xRTT), and new radio technologies. If the capability information reporting request message includes information such as radio (NR), it indicates that the requested frequency band is not included in the capability information reporting request message. If the capability information reporting request message also includes requested frequency band information in addition to UTRA, EUTRA, GERAN-CS, GERAN-PS, CDMA2000-1xRTT, and NR, it indicates that the capability information reporting request message includes the requested frequency band. For example, the requested frequency band information can be the frequency band information (requested Frequency Bands) required in 3GPP protocol R11 version and above.

[0134] S407a. The terminal device sends the second CA combination information to the network device. Correspondingly, the network device receives the second CA combination information from the terminal device, which is determined by the terminal device based on the frequency band to be reported.

[0135] In other words, the terminal device can send the second CA combination information to the network device in response to the capability information reporting request message including the frequency band to be reported; correspondingly, the network device can receive the second CA combination information from the terminal device when the capability information reporting request message includes the frequency band to be reported.

[0136] S407b: The terminal device sends the first frequency band information and the first CA combination information to the network device, and the network device receives the first frequency band information and the first CA combination information from the terminal device.

[0137] In other words, the terminal device may send the first frequency band information and the first CA combination information to the network device in response to the capability information reporting request message not including the frequency band to be reported; correspondingly, the network device may receive the first frequency band information and the first CA combination information from the terminal device when the capability information reporting request message does not include the frequency band to be reported.

[0138] In an optional implementation, the relevant description of step S407b can be found in the description of step S304 above, and will not be repeated here.

[0139] S404b: The terminal device receives a capability information reporting request message from the network device, and in turn, the network device sends a capability information reporting request message to the terminal device.

[0140] In one alternative implementation, steps S408 to S409b may also be performed after step S404b.

[0141] S408. The terminal device determines whether the capability information reporting request message includes the frequency band to be reported; if yes, proceed to step S409a; if no, proceed to step S409b.

[0142] S409a. The terminal device sends the second CA combination information to the network device. Correspondingly, the network device receives the second CA combination information from the terminal device. The second CA combination information is determined by the terminal device based on the frequency band that is required to be reported.

[0143] S409b: The terminal device sends the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capability of the terminal device to support frequency band information and CA combination information, until the maximum value of the frequency band information and CA combination information queried by the network device is reached. Correspondingly, the network device receives the frequency band information and CA combination information supported by the terminal device in sequence.

[0144] In other words, in response to a capability information reporting request message that does not include the requested frequency band, the terminal device can sequentially send the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capabilities of the frequency band information and CA combination information supported by the terminal device, until the maximum value of the frequency band information and CA combination information queried by the network device is reached; correspondingly, the network device can sequentially receive the frequency band information and CA combination information supported by the terminal device even if the capability information reporting request message does not include the requested frequency band.

[0145] In an optional implementation, the relevant description of step S409 can be found in the description of step S305 above, and will not be repeated here.

[0146] In this embodiment of the application, either step S404b or step S405 can be executed. Specifically, if the terminal device determines that the first PLMN or the first MNC does not exist in the first information, it executes step S404b; if it determines that the first PLMN or the first MNC exists in the first information, it can execute step S405 after executing step S404a.

[0147] In this embodiment, after receiving a capability information reporting request message from a network device, if the terminal device determines that the capability reporting request message does not include the frequency band to be reported, it can send the first frequency band information and the first CA combination information to the network device. Alternatively, it can send the frequency band information and CA combination information supported by the terminal device to the network device in descending order of their supported capabilities, until the maximum value of the frequency band information and CA combination information queried by the network device is reached. This allows the network device to obtain the maximum supported CA combination information based on the frequency band information and CA combination information reported by the terminal device, thereby improving the data transmission rate between the terminal device and the network device.

[0148] Furthermore, in scenarios where the terminal device supports more than 128 CA combination information, but the network device only queries 128 CA combination information (i.e., the maximum number of frequency band information and CA combination information queried by the network device is 128), the communication method provided in this application embodiment, compared to the method where the terminal device randomly reports the CA combination information supported by the terminal device to the network device after receiving a capability information reporting request message from the network device, not only increases the probability of the terminal device reporting the maximum CA combination information supported under the current network, but also avoids the problem that the reported CA combination information is not supported by the current network (for example, if the current network is the China Telecom network, the CA combination information supported by the terminal device randomly reported by the terminal device only includes the CA combination information supported by the terminal device under the China Mobile and China Unicom networks, in which case the CA combination information randomly reported by the terminal device is not supported by the current network). This is beneficial to improving the data transmission rate between the terminal device and the network device, and thus improving the user's experience when transmitting data.

[0149] Furthermore, compared to the method where, after receiving a capability information reporting request message from a network device, the terminal device reports CA combination information to the network device sequentially according to the order of CA combination information supported by the terminal device in a single frequency band (band), where the priority of downlink transmission (DL) 2CC is higher than that of DL 3CC, and the priority of DL 3CC is higher than that of uplink transmission (UL) CA, the communication method provided in this application can reduce the probability that the terminal device will miss reporting the maximum CA combination information supported by the terminal device in the current network and the uplink transmission CA combination information. This is beneficial for the network device to obtain the maximum CA combination information that both can support based on the frequency band information and CA combination information reported by the terminal device, thereby improving the data transmission rate of the terminal device and the network device.

[0150] Among them, DL 2CC means that the downlink transmission capability information is the aggregation of 2 CCs; DL 3CC means that the downlink transmission capability information is the aggregation of 3 CCs; UL CA means that the uplink transmission capability information is the combination of CA information.

[0151] This application also provides another communication method, with... Figure 2 , Figure 3 and Figure 4The difference in the communication method shown is that, in this method, the terminal device can determine a first frequency band list (e.g., frequency band list A) based on the frequency band information supported by the terminal device in communication networks corresponding to multiple different PLMNs or different MNCs. This first frequency band list stores the frequency band combination information supported by the terminal device in communication networks corresponding to different PLMNs or different MNCs. In response to the existence of the first PLMN or the first MNC in the first frequency band list, the terminal device obtains a second frequency band list (e.g., frequency band list X) from the first frequency band list. This second frequency band list includes the frequency band combination information supported by the terminal device in the communication network corresponding to the first PLMN or the first MNC. The first PLMN is the PLMN in the IMSI corresponding to the USIM card in the terminal device, and the first MNC is the MNC in the IMSI corresponding to the USIM card in the terminal device. The terminal device receives a capability information reporting request message from the network device, and correspondingly, the network device sends a capability information reporting request message to the terminal device. The terminal device sends dual connectivity (DC) frequency band combination information to the network device according to the second frequency band list, and correspondingly, the network device receives the DC frequency band combination information.

[0152] Optionally, this communication method can be applied to 5G (5th-Generation Mobile Communication) scenarios.

[0153] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of a communication device provided in an embodiment of this application. Figure 5 As shown, the communication device may include a receiving unit 501 and a transmitting unit 502.

[0162] In this embodiment, the sending unit 502 is further configured to: respond to the capability information reporting request message not including the frequency band to be reported, perform the step of sending the first frequency band information and the first CA combination information to the network device; or, perform the step of sequentially sending the frequency band information and CA combination information supported by the terminal device to the network device in descending order of the capability of the frequency band information and CA combination information supported by the terminal device, until the maximum value of the frequency band information and CA combination information queried by the network device is reached.

[0163] In this embodiment, the sending unit 502 is further configured to: in response to the capability information reporting request message including a frequency band to be reported, send second CA combination information to the network device; the second CA combination information is determined by the terminal device based on the frequency band to be reported.

[0164] In this embodiment, the communication device may further include a storage unit 505.

[0166] In this embodiment, if the number of frequency band information and CA combination information sent to the network device does not reach the maximum value of the frequency band information and CA combination information queried by the network device, the sending unit 502 is further configured to send the third frequency band information and the third CA combination information to the network device in descending order of the capabilities of the third frequency band information and the third CA combination information until the maximum value of the frequency band information and CA combination information queried by the network device is reached; wherein, the third frequency band information and the third CA combination information are frequency band information and CA combination information other than the first frequency band information and the first CA combination information supported by the terminal device.

[0167] In another alternative implementation, the communication device is used to perform the operations of the network device in the above-described communication method, for example:

[0168] The sending unit 502 is used to send a capability information reporting request message to the terminal device;

[0169] The receiving unit 501 is used to receive first frequency band information and first carrier aggregation (CA) combination information from the terminal device;

[0170] The first frequency band information and the first CA combination information are the frequency band information and CA combination information supported by the terminal device under the communication network corresponding to the first public land mobile network PLMN or the first mobile network number MNC;

[0171] The first PLMN is the PLMN of the cell selected by the terminal device, and the first MNC is the MNC corresponding to the first PLMN.

[0172] In this embodiment, the receiving unit 501 is further configured to: sequentially receive frequency band information and CA combination information supported by the terminal device; the frequency band information and CA combination information supported by the terminal device have been sorted in descending order of capability.

[0173] In this embodiment, the receiving unit 501 is further configured to: perform the step of receiving first frequency band information and first CA combination information from the terminal device when the capability information reporting request message does not include the frequency band to be reported; or, perform the step of sequentially receiving frequency band information and CA combination information supported by the terminal device.

[0175] In this embodiment, if the number of frequency band information and CA combination information received from the first frequency band information and the first CA combination information from the terminal device does not reach the maximum value of frequency band information and CA combination information queried by the network device, the receiving unit 501 is further configured to sequentially receive the third frequency band information and the third CA combination information from the terminal device; wherein, the third frequency band information and the third CA combination information are frequency band information and CA combination information other than the first frequency band information and the first CA combination information supported by the terminal device; the third frequency band information and the third CA combination information have been sorted in descending order of capability.
