The exemplary embodiments of this application and the descriptions thereof are used to explain this application and do not constitute an improper limitation on this application. In the accompanying drawings:.

The present invention is defined by the attached independent claims. Advantageous embodiments are described in the attached dependent claims. Embodiments and/or examples mentioned in the description that do not fall under the scope of the claims are useful for understanding the present invention. To make the objectives, technical solutions, and advantages of this application clearer, the following clearly and completely describes the technical solutions of this application with reference to specific embodiments of this application and the corresponding accompanying drawings. Apparently, the described embodiments are merely some rather than all of the embodiments of this application.

It should be understood that, the technical solutions of the embodiments of the present disclosure may be applied to various communications systems, for example: a global system for mobile communications (Global System of Mobile communication, GSM), a code division multiple address (Code Division Multiple Access, CDMA) system, a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, a general packet radio service (General Packet Radio Service, GPRS), a long term evolution (Long Term Evolution, LTE) system, an LTE frequency division duplex (Frequency Division Duplex, FDD) system, an LTE time division duplex (Time Division Duplex, TDD) system, a universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), a Worldwide Interoperability for Microwave Access (Worldwide Interoperability for Microwave Access, WiMAX) communications system, a <NUM> system, a new radio (New Radio, NR) system, or a subsequent evolved communications system.

In the embodiments of the present disclosure, a terminal device may include but is not limited to a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal), a mobile telephone (Mobile Telephone), a user equipment (User Equipment, UE), a handset (handset), a portable device (portable equipment), a vehicle (vehicle), and the like. The terminal device may communicate with one or more core networks by using a radio access network (Radio Access Network, RAN). For example, the terminal device may be a mobile phone (or referred to as a "cellular" phone), or a computer having a wireless communication function; or the terminal device may be a portable, pocket-sized, handheld, computer built-in, or in-vehicle mobile apparatus.

In the embodiments of the present disclosure, a network device is an apparatus that is deployed in a radio access network and that is used to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various types of macro base stations, micro base stations, relay nodes, and access points. In systems using different radio access technologies, names of devices having a base station function may be different. For example, such a device is called an evolved NodeB (evolved NodeB, eNB or eNodeB) in an LTE network, a Node B (Node B) in a 3rd generation (3rd Generation, <NUM>) network, or a network device in a subsequent evolved communications system (for example, a next generation base station (next generation node base station, gNB)), but the use of the words does not constitute a restriction.

As shown in <FIG>, an embodiment of the present disclosure provides a wireless communication method <NUM>. The method is executed by a terminal device, and the terminal device is equipped with a plurality of smart cards simultaneously, for example, two, three, or more. The method includes the following step:
S102: Send a message, where the message is used to indicate that a plurality of UEs have an association relationship.

The terminal device in the embodiments of this specification refers to a physical terminal device equipped with a plurality of smart cards.

The UE provided in the embodiments of this specification may refer to functions of communication transmitting-receiving protocols corresponding to a smart card, for example, protocol stacks including Non-Access Stratum (Non-Access Stratum, NAS), Radio Resource Control (Radio Resource Control, RRC), Packet Data Convergence Protocol (Packet Data Convergence Protocol, PDCP), and Radio Link Control (Radio Link Control, RLC). Each UE can independently receive a dispatching, configuration, or power control command from a network device, and receive and send data under the control of the network device. That is, the UE may be a protocol entity corresponding to a smart card in the terminal device plus the smart card. According to the invention, the smart cards that the terminal device is equipped with have a one-to-one correspondence with the UEs in this step.

Therefore, it may be understood that one terminal device is a physical carrier of a plurality of logical UE functions, and each logical UE function corresponds to one smart card. In the embodiments of this specification, the logical UE function is also referred to as a UE corresponding to a smart card.

The smart card in the embodiments of this specification may also be referred to as a SIM card, or the like. In addition, the smart card in the embodiments of this specification may be an entity card, or may be a virtual card, for example, an embedded-SIM (embedded-SIM, eSIM) card.

In this step, the terminal device can send the message via at least one of the UEs. If at least two UEs each send a message (which is not encompassed by the wording of the claims, but is considered as useful for understanding the invention), functions of the messages sent by the at least two UEs may be the same, for example, may be used to indicate that the UEs corresponding to the smart cards that the terminal device is equipped with have an association relationship, or may be used to indicate that the UEs share a capability of the terminal device.

According to the invention, the message is specifically used to indicate that the UEs share a capability of the terminal device. In this way, after receiving the message, the network device learns that the UEs have an association relationship, that is, the network device learns that the terminal device is equipped with the smart cards. Therefore, the network device subsequently takes the maximum sending power of the terminal device into consideration based on the capability of the terminal device when performing uplink scheduling for the UEs, so that the sum of transmission rates of the UEs is smaller than or equal to the maximum transmission rate of the terminal device, avoiding problems such as data loss.

Before this embodiment of the present disclosure is implemented, the terminal device reports capability information via at least one of the UEs. The reported capability includes but is not limited to the following: the maximum data rate (max data rate) supported by the terminal device, which can be obtained by the network device through calculation based on a supported band or supported band combinations (band combinations) that are reported; and an uplink transmit power supported by the terminal device, which can be obtained by the network device based on reported UE power class (ue-PowerClass). According to the invention the capability of the terminal device also comprises a buffer size of the terminal device.

For ease of differentiation, the UE that sends the message in this embodiment may be referred to as a first UE. A UE other than the first UE of the terminal device is referred to as a second UE. That is, the second UE does not send messages. In a specific example, there is one first UE, and one or more second UEs. In another specific example not encompassed by the wording of the claims, there are a plurality of first UEs. To improve transmission reliability of first messages, the first UEs each send a first message. There may be one or more, or, in examples not encompassed by the wording of the claims, zero second UEs.

The message includes an identifier of the second UE, for example, a cell radio network temporary identifier (Cell Radio Network Temporary Identifier, C-RNTI) allocated by a serving cell for the second UE, an international mobile subscriber identity (International Mobile Subscriber Identity, IMSI) of the second UE, or a temporary mobile subscriber identity (System Architecture Evolution Temporary Mobile Subscriber Identity, SAE-Temporary Mobile Subscriber Identity, S-TMSI) of the second UE obtained by a second UE NAS entity from the network side.

Optionally, after the sending a message, the method may further include the following step: receiving a response message, where the response message is used to indicate whether the message is successfully received. In this way, when the network device fails to receive the message, the terminal device can perform operations such as a message retransmission.

According to the wireless communication method provided in this embodiment of the present disclosure, the terminal device equipped with the smart cards sends the message to the network device, and the message is used to indicate that the UEs have an association relationship. In this way, the network device subsequently takes the maximum sending power of the terminal device into consideration based on the capability of the terminal device when performing uplink scheduling for the UEs, so that the sum of transmission rates of the UEs is smaller than or equal to the maximum transmission rate of the terminal device, avoiding problems such as data loss.

Based on the embodiment shown in <FIG>, optionally, the sending a message in step S102 includes: sending the message when at least two of the UEs are in an RRC connected state. Each smart card of the terminal device corresponds to a UE.

In the foregoing embodiments, the sending a message in step S102 includes: sending the message via at least one of the UEs (according to the invention the message is sent by only a first logical UE function). Functions of messages sent by the UEs may be the same, to improve message transmission reliability.

In the foregoing embodiments, public land mobile networks (Public Land Mobile Network, PLMN) to which the terminal device is connected via the UEs are the same. In this way, when network devices to which the UEs are connected are different, the network devices directly perform communication and coordination, and further dispatch different UEs of the terminal device. Certainly, in a special case, when PLMNs to which the UEs are connected are different, different operators can coordinate to dispatch different UEs of the terminal device.

That PLMNs to which the UEs are connected are the same may specifically be:.

There is at least one same registered PLMN or equivalent PLMN for the UEs. For example, registered PLMNs and equivalent PLMNs of the UEs are all the same. Alternatively, there is one same registered PLMN or equivalent PLMN for the UEs.

The message in the foregoing embodiments may specifically include at least one of the following: an identifier of a second UE;.

Considering that the message is sent by the first UE, the network device can learn the identifier of the first UE and the identifier of the first cell. To reduce signaling overheads, the message includes the identifier of the second UE. Alternatively, when a cell to which the terminal device is connected via the first UE and a cell to which the terminal device is connected via the second UE are different, the message includes the identifier of the second UE and the identifier of the second cell, as according to the claimed invention.

The identifier of the UE mentioned above may specifically be a C-RNTI, an IMSI, an S-TMSI, or the like.

Optionally, cells to which the terminal device is connected via the UEs are the same; or cells to which the terminal device is connected via the UEs are different.

The following describes the wireless communication method provided in this embodiment of the present disclosure in detail with reference to a specific embodiment. In the embodiment, the first UE and the second UE are connected to a same serving cell, a UE ID (for example, a C-RNTI, an IMSI, an S-TMSI, or the like) of the first UE is A, and a UE ID of the second UE is B.

The first UE reports, to the network device, that the first UE and another UE that is in an RRC connected state share the capability of the terminal device and the ID of the second UE is B. Certainly, if the terminal device has a plurality of second UEs, UE IDs of the second UEs can be reported at a time.

Alternatively, the terminal device has two UEs (first UE and second UE) that are in a connected state and that share a capability of the terminal device, and UE IDs of the two UEs are A and B, respectively.

After receiving the reported information, the network device leans that the first UE and the second UE share the capability of the terminal device, and based on this, performs subsequent operations such as dispatching and power control on the two UEs.

In another embodiment (second embodiment), serving cells to which the first UE and the second UE are connected are different: the first UE is connected to a cell X, and a UE ID (for example, a C-RNTI, an IMSI, an S-TMSI, or the like) of the first UE is A; and the second UE is connected to a cell Y, and a UE ID of the second UE is B.

The first UE reports, to the network device, that the first UE and another UE that is in an RRC connected state (the second UE) share a capability of the terminal device, the second UE is connected to the cell Y, and the UE ID of the second UE is B.

Alternatively, the terminal device has two UEs (a first UE and a second UE) that are in a connected state and that share a capability of the terminal device, cell IDs of the two UEs are X and Y, respectively; and UE IDs of the two UEs are A and B, respectively.

After receiving the reported information, the network device leans that the first UE and the second UE share the capability of the terminal device, and based on this, performs subsequent operations such as dispatching and power control on the two UEs. Optionally, when the cell X and the cell Y do not belong to a same network device, network devices need to perform coordination.
