[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on March 26, 2024, with application number 202410359364.2 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0004] Current terminal devices (such as mobile phones) include not only the common single-SIM phones, but also a large number of dual-SIM dual-standby phones. Dual-SIM dual-standby refers to a phone that can accommodate two subscriber identification module (SIM) cards / universal integrated circuit cards (UICC), and both cards can be in standby mode simultaneously. Accordingly, there are the concepts of dual-SIM dual standby dual communication (abbreviated as dual-SIM dual communication) and dual-SIM dual standby single communication (dual-SIM single communication). Dual-SIM dual communication and dual-SIM single communication can also be considered two operating modes of a terminal device. The so-called "single communication" or "dual communication" refers to whether the two SIM cards in a phone can perform services simultaneously (for example, both cards can make calls at the same time). If the two SIM cards in a phone can perform services simultaneously, then the phone is dual-SIM dual communication. If the two SIM cards in a phone cannot perform services simultaneously, then the phone is dual-SIM single communication.

[0005] For a terminal device of a dual-SIM dual-standby mobile phone, if the scheduling of the network device does not match the actual working mode of the terminal device, the communication performance of the terminal device will be low. Summary of the Invention

[0006] The embodiments of the present application provide a communication method and apparatus for enabling a network device to schedule a terminal device according to an actual working mode of the terminal device to improve communication performance.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] In a first aspect, embodiments of the present application provide a communication method, which is applied to a terminal side, for example, a terminal device or a component (such as a circuit, a chip, or a chip system) in the terminal device. For ease of description, the following example uses the method applied to a terminal device, where the terminal device has two user equipment identities.

[0009] The communication method includes: a terminal device sending first information to a network device, receiving second information from the network device, and sending uplink information to the network device based on the second information. The first information is used to instruct the terminal device to send information in a first frequency band using a first method, where the first method is a time division multiplexing method or a dual-SIM dual-pass method. The second information includes scheduling information of the terminal device, and the second information is associated with the first information.

[0010] The first information is used to instruct the terminal device to transmit information in the first frequency band using the first method. This can also be understood as indicating that the terminal device desires the network device to schedule the terminal device using time-division multiplexing or dual-SIM dual-pass. In this method, a terminal device with two user identities can report to the network device the time-division multiplexing or dual-SIM dual-pass mode it is actually using. Accordingly, the network device schedules the terminal device according to the method reported by the terminal device. This method allows the network device to schedule the terminal device according to its actual operating mode, thereby improving communication performance.

[0011] In one implementation, the terminal device communicates with the network device through the first cell using two user identities. It can also be understood that the two user identities of the terminal device are in the same cell.

[0012] In one implementation, the two user identities include a first user identity and a second user identity, and the first information includes one or more of the following: first indication information or first time information. The first indication information indicates whether uplink radio frequency switching of the first user identity will cause downlink transmission interruption of the second user identity. The first time information indicates the interval between the switching of the two user identities.

[0013] The first information may also include information that assists the network device in scheduling the terminal device. For example, the first information may include first instruction information to assist the network device in synchronizing with the terminal device to reduce the risk of uplink radio frequency switching of the first user identity interrupting downlink transmission of the second user identity. For another example, the first information may also include first time information to ensure that the terminal device has sufficient processing time for the two user identities to switch.

[0014] In one implementation, the method further includes: the terminal device sending third information to the network device, where the third information is used to indicate the priority of the two user identities, or the third information is used to indicate the size of the time domain resources required by each of the two user identities.

[0015] The third information can assist network devices in properly scheduling terminal devices to improve their communication performance. For example, when resources are limited, scheduling of high-priority user identities can be prioritized, thereby ensuring normal communication for these high-priority user identities. For another example, resources can be appropriately allocated between two user identities based on their respective time domain resource requirements to best meet their actual needs.

[0016] In one implementation, the first information is used to instruct the terminal device to send information in a first frequency band in a first manner, including: the first information is used to instruct the terminal device to send information in a first frequency band combination in at least one manner, wherein at least one manner has a corresponding relationship with the frequency band included in the first frequency band combination, and the first frequency band combination includes the first frequency band.

[0017] In this method, the terminal device reports to the network device the communication mode used on each frequency band within the frequency band combination (such as time division multiplexing mode or dual-card dual-pass mode), so that the network device schedules the terminal device in a certain frequency band with the corresponding communication mode to ensure the communication performance of the terminal device as much as possible.

[0018] In one implementation, the first information is included in the capability information of the terminal device, or the first information is carried in a radio resource control (RRC) message or a terminal device assistance information (UAI) message.

[0019] The solution lists the carrying method of the first information, and does not limit the specific method used. For example, the communication method used (such as time division multiplexing or dual-SIM dual-channel) can be regarded as a capability of the terminal device and notified to the network device through capability information.

[0020] In a second aspect, embodiments of the present application provide a communication method, which is applied to a network side, for example, a network device or a component (such as a circuit, a chip, or a chip system) in the network device. For ease of description, the following takes the application of the method to a network device as an example.

[0021] The communication method includes: a network device receiving first information from a terminal device and sending second information. The first information is used to instruct the terminal device to send information in a first frequency band using a first mode. The terminal device has two user identities, and the first mode is a time division multiplexing mode or a dual-SIM dual-pass mode. The second information is used to instruct the terminal device to send uplink information using the first mode.

[0022] In one implementation, the network device communicates with two user identities of the terminal device through the first cell.

[0023] In one implementation, the two user identities of a terminal device include a first user identity and a second user identity, and the first information includes one or more of the following: first indication information or first time information. The first indication information indicates whether uplink radio frequency switching of the first user identity will cause downlink transmission interruption of the second user identity. The first time information indicates the interval between switching between the two user identities of the terminal device.

[0024] In one implementation, the method further includes: the network device receives third information from the terminal device, where the third information is used to indicate the priority of the two user identities of the terminal device, or the third information is used to indicate the size of the time domain resources required by the two user identities of the terminal device.

[0025] In one implementation, the first information is used to instruct a terminal device to transmit information in a first frequency band in a first manner, including: the first information is used to instruct the terminal device to transmit information in a first frequency band combination in at least one manner. The at least one manner corresponds to a frequency band included in the first frequency band combination, and the first frequency band combination includes the first frequency band.

[0026] In one implementation, the first information is included in the capability information of the terminal device; or, the first information is carried in an RRC message or a UAI message.

[0027] The beneficial effects of the second aspect and its various implementations can refer to the beneficial effects of the first aspect and its various implementations, and will not be repeated here.

[0028] In a third aspect, embodiments of the present application provide a communication method, which is applied to a terminal side, for example, a terminal device or a component (such as a circuit, a chip, or a chip system) in the terminal device. For ease of description, the following example uses the method applied to a terminal device, where the terminal device has two user device identities, for example, a first user identity and a second user identity.

[0029] The communication method includes: a terminal device reselects from a first cell to a second cell, and receives a paging message as a first user identity and a second user identity, wherein the second cell does not support the first user identity acting as a proxy for the second user identity to receive the paging message.

[0030] In this solution, when a terminal device moves from one cell to another, it can receive paging messages as both the first and second user identities by default. Compared to receiving paging messages as one user identity on behalf of another, this can reduce missed paging messages, thereby ensuring normal communication for the terminal device.

[0031] In one implementation, the method further includes: the terminal device receiving second indication information from the network device, where the second indication information is used to indicate that the second cell does not support the first user identity acting as a proxy for the second user identity to receive a paging message.

[0032] In this solution, the terminal device can determine whether to receive paging messages as one user identity on behalf of another user identity based on the second indication information. For example, if the second cell does not support the first user identity receiving paging messages on behalf of the second user identity, the terminal device can receive paging messages as the first user identity and the second user identity, thereby reducing missed paging messages. For another example, if the second cell supports the first user identity receiving paging messages on behalf of the second user identity, the terminal device can receive paging messages as the first user identity on behalf of the second user identity, thereby reducing the power consumption of the terminal device.

[0033] In a fourth aspect, embodiments of the present application provide a communication method, which is applied to a terminal side, for example, a terminal device or a component (such as a circuit, a chip, or a chip system) in the terminal device. For ease of description, the following example uses the method applied to a terminal device, where the terminal device has two user device identities, for example, a first user identity and a second user identity.

[0034] The communication method includes: a terminal device reselecting from a first cell to a second cell, and receiving a paging message as a first user identity and a second user identity. The first user identity is in the first cell, the second user identity is in the second cell, and the first and second cells are within the same paging range. Alternatively, the first user identity is in the first cell, the second user identity is in the second cell, and the first cell is within a first paging range and the second cell is within a second paging range.

[0035] The paging range can also be understood as a group of tracking areas (TA) or a group of routing areas (RA). When the two user identities of the terminal device are not in the same cell and are in the same TA / RA list, the terminal device receives the paging message as two user identities. Compared with the case where the terminal device receives the paging message through one user identity acting as another user identity, it can avoid losing the cell-level system message, thereby ensuring the normal communication of the terminal device as much as possible. Similarly, when the two user identities of the terminal device are not in the same cell and are not in the same TA / RA list, the terminal device receives the paging message as two user identities. Compared with the case where the terminal device receives the paging message through one user identity acting as another user identity, it can avoid losing the paging message, thereby ensuring the normal communication of the terminal device as much as possible.

[0036] In a fifth aspect, an embodiment of the present application provides a communication method that can be performed by a first communication device and a second communication device. The first communication device has the function of implementing the behavior in the method example of the first aspect. For example, the first communication device includes corresponding means (means) or modules or units for executing the method of the first aspect, and the modules or means or units can be implemented by software and / or hardware. The second communication device has the function of implementing the behavior in the method example of the second aspect. For example, the second communication device includes corresponding means (means) or modules or units for executing the method of the second aspect, and the modules or means or units can be implemented by software and / or hardware. The following takes the first communication device as a terminal device and the second communication device as a network device as an example.

[0037] The communication method includes: a terminal device sends first information to a network device, the first information is used to instruct the terminal device to send information in a first frequency band in a first manner, the first manner being a time division multiplexing manner or a dual-card dual-pass manner; the network device sends second information to the terminal device, the second information is used to instruct the terminal device to send uplink information in the first manner; the terminal device sends uplink information to the network device in the first manner.

[0038] Regarding the beneficial effects of the fifth aspect, reference may be made to the beneficial effects of the first aspect and its various implementation methods, which will not be repeated here.

For example, the communication device: includes a processing unit (sometimes also referred to as a processing module or processor) and / or a transceiver unit (sometimes also referred to as a transceiver module or transceiver). The transceiver unit can realize the sending function and the receiving function. When the transceiver unit realizes the sending function, it can be called a sending unit (sometimes also referred to as a sending module).

The sending unit and the receiving unit can be the same functional unit, which is called a transceiver unit, and the functional unit can realize the sending function and the receiving function; or, the sending unit and the receiving unit can be different functional units, and the transceiver unit is a general term for these functional units. These units (modules) can perform the corresponding functions in the method examples of any aspect of the first aspect to the fourth aspect above.

[0059] The technical solutions provided in the embodiments of the present application can be applied to various wireless communication systems. For example, the method provided in the embodiments of the present application can be applied to communication systems related to the 3rd Generation Partnership Project (3GPP), such as long term evolution (LTE), the sixth generation (5G) mobile communication system (such as new radio (NR) communication system), or can also be applied to future mobile communication systems or other similar communication systems. Other similar communication systems may include wireless fidelity (WIFI), vehicle to everything (V2X), Internet of Things (IoT) system, narrowband Internet of Things (NB-IoT) system, and the like.

[0060] Please refer to Figure 1, which shows a communication system applicable to an embodiment of the present application. The communication system includes a wireless access network 100 and a core network. Optionally, the communication system may also include the Internet.

[0061] The wireless access network 100 may include at least one network device and at least one terminal device. For example, the wireless access network 100 includes two network devices 110a and 110b and terminal devices 120a through 120j. The network architecture shown in FIG1 is for illustration only; the number of terminal devices and / or network devices may be fewer or greater. The communication system described in the embodiments of the present application is intended to more clearly illustrate the technical solutions of the embodiments of the present application and does not constitute a limitation on the communication systems to which the embodiments of the present application are applicable. For example, the communication system may also include other devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1. ​​The network architecture and application scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. Persons skilled in the art will appreciate that, as network architectures evolve and new application scenarios emerge, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems. When applying the technical solutions of the embodiments of the present application to other communication systems, the devices, components, modules, etc. in the embodiments may be replaced with corresponding devices, components, and modules in other communication systems without limitation.

[0062] The network devices involved in the embodiments of the present application are mainly access network devices. Therefore, in the following text, unless otherwise specified, the "network devices" referred to are radio access network (RAN) devices, which can be referred to as access network devices for short. RAN can be a 3GPP-related cellular system, for example, a 5G mobile communication system, or a future-oriented evolution system (such as a 6G mobile communication system). RAN can also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (cloud radio access network, CRAN), or a virtualized radio access network (virtualized RAN, vRAN), etc. RAN can also be a communication system that is a fusion of two or more of the above systems. RAN devices can also be referred to as RAN nodes, RAN entities, or access nodes, etc.

[0063] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), or a base station in a future mobile communication system. A RAN node can be a macro base station, a micro base station, an indoor station, a relay node, a donor node / host node, or a wireless controller. A RAN node can also be a server, a wearable device, a vehicle, or an onboard device. For example, a RAN node in V2X technology can be a roadside unit (RSU).

[0064] In another possible scenario, the RAN node may be a module or unit that performs part of the functions of the base station; or multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, and different RAN nodes respectively perform part of the functions of the base station. For example, the RAN node may be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The functions of the CU may be implemented by one entity, or by different entities. For example, the functions of the CU may be further divided, that is, the control plane and the user plane may be separated and implemented by different entities, namely the control plane CU entity (i.e., CU-control plane (CP) entity) and the user plane CU entity (i.e., CU-user plane (UP) entity). The CU-CP entity and the CU-UP entity may be coupled with the DU to jointly perform the functions of the RAN node. The CU and DU may be set separately, or may be included in the same network element, such as the baseband unit (BBU).

[0065] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0066] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (such as the RRC layer) and / or the service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the radio link control (RLC), the media access control (MAC) layer, and / or the physical (PHY) layer, etc.). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (such as the RLC layer, the MAC layer, and / or the PHY layer, etc.). For a detailed description of each of the above protocol layers, please refer to the relevant technical specifications of 3GPP or the technical specifications of other applicable communication protocols. The above division of the processing functions of the CU and DU according to the protocol layer is only an example, and can also be divided in other ways, which is not limited by this application. For example, in one design, the CU or DU can also be divided into parts with partial processing functions of the protocol layer. In one design, part of the RLC layer functions and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU.

[0067] In the embodiments of the present application, the device for implementing the functions of the network device can be the network device itself, or a device that can support the network device to implement the functions, such as a chip system or a combination of devices or components that can implement the functions of the network device, which can be installed in the network device. The embodiments of the present application do not limit the specific technology and specific device form used by the network device.

[0068] Terminal devices, also known as terminals, user equipment (UE), mobile stations, or mobile terminals, etc. In the embodiments of the present application, anything that can communicate data with a base station can be considered a terminal device. Terminal devices can be widely used in various scenarios, such as device-to-device (D2D) communication, V2X communication, machine-type communication (MTC), IoT, virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, or smart city. For example, the terminal device can be: a mobile phone, a computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a robotic arm, a camera, a robot, or a smart home device (such as a TV, air conditioner, vacuum cleaner, speaker, set-top box), a relay, a customer premise equipment (CPE), a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a robotic arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0069] The various terminal devices introduced above, if located on a vehicle (for example, placed / installed in a vehicle), can all be considered as on-board terminal devices. The on-board terminal device can be an on-board module, on-board module, on-board component, on-board chip or on-board unit built into the vehicle as one or more components or units, and the vehicle can implement the method of the present application through the built-in on-board module, on-board module, on-board component, on-board chip or on-board unit. The on-board terminal device can be a complete vehicle device, an on-board module, a vehicle, an on-board unit (OBU), an RSU, a telematics box (T-box), a chip or a system on chip (SOC), etc. The above chip or SOC can be installed in a vehicle, an OBU, an RSU or a T-box.

[0070] In the embodiments of the present application, the device for implementing the functions of the terminal device can be the terminal device itself, or a device capable of supporting the terminal device in implementing the functions, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device, which can be installed in the terminal device. The embodiments of the present application do not limit the specific technology and specific device form used by the terminal device.

[0071] The network architecture / system and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. A person skilled in the art will appreciate that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are equally applicable to similar technical problems.

[0072] Current terminal devices (such as mobile phones) include not only common single-SIM phones, but also a large number of dual-SIM dual-standby phones on the market. Dual-SIM dual-standby means that the mobile phone has two user identities, and the two user identities can be on standby at the same time. "User identity" (such as the first user identity or the second user identity, etc.) is a logical concept. For example, "user identity" can correspond to a SIM card, subscriber information, a virtual SIM card, a user identifier (such as an international mobile subscriber identity (IMSI), or a temporary mobile subscriber identity (TMSI), etc.). From the perspective of the network side, different "user identities" logically correspond to different communication entities served by the network side, such as the UE in 4G and 5G systems. For example, a terminal device that supports two user identities can be regarded as two communication entities for the network side. For another example, when the "user identity" corresponds to a SIM card or subscriber information, the network side will identify two terminal devices that support different SIM cards or different subscriber information as two different communication entities, and will also identify the same terminal device that supports multiple different SIM cards or multiple subscriber information as multiple different communication entities, even if in fact, the terminal device that supports multiple different SIM cards or multiple subscriber information is only one physical entity.

[0073] In the embodiments of this application, the "user identity" corresponding to the SIM card will be mainly used as an example for explanation. For example, the SIM card can be understood as the key for the terminal device to access the mobile network. For the sake of convenience of description, the SIM card and its evolution are collectively referred to as SIM card in the embodiments of this application. For example, the SIM card can be an identity card for a global system for mobile communications (GSM) digital mobile phone user, which is used to store the user's identity code and key and support the GSM system to authenticate the user; for another example, the SIM card can also be a universal subscriber identity module (USIM), which can also be called an upgraded SIM card. From this perspective, dual-SIM dual standby means that two SIM cards can be inserted into the mobile phone, and the two cards can be on standby at the same time.

[0074] The two SIM cards in a mobile phone can belong to the same or different mobile operators and the same or different standards, including NR, LTE, wideband code division multiple access (WCDMA), time division multiple access (TDMA) 2000, or GSM.

[0075] For mobile phones that support inserting two SIM cards, they also support dual SIM dual standby mode. Mobile phones in dual SIM dual standby mode can generally be set to the following situations: <1> , only SIM1 card is enabled; <2> , only SIM2 card is enabled; <3> , dual SIM cards are turned on. Among them, dual SIM dual standby with different cards supporting different standards is also called dual-network dual standby or dual-mode dual standby. There is also the concept of dual SIM dual standby dual pass / dual SIM dual pass (dual SIM dual active, DSDA), or dual SIM dual standby single pass / dual SIM single pass. The so-called "single pass" or "dual pass" refers to whether the two cards in a mobile phone can perform services at the same time (for example, two cards can make calls at the same time). If the two cards in a mobile phone can perform services at the same time, then the mobile phone is dual SIM dual pass, and if the two cards in a mobile phone cannot perform services at the same time, then the mobile phone is dual SIM single pass. In the embodiment of the present application, "single pass" or "dual pass" refers to the transmission from the terminal device to the network device.

[0076] Dual-SIM single-call allows two SIM cards to maintain RRC connections with the network simultaneously, switching between them using time division multiplexing (TDM). TDM means that only one user identity is available at a time, and the two user identities occupy the wireless / RF module in different time periods. For example, the time that SIM1 and SIM2 in a mobile phone occupy the wireless / RF module can be specified. To support flexible TDM, the base station can configure the operating time of the two SIM cards in each phone according to the needs of each phone.

[0077] Dual-SIM dual-channel can maintain the RRC connection of two SIM cards with the network at the same time, and the two SIM cards occupy the wireless / RF module independently, and both SIM cards can be used at the same time.

[0078] Dual-SIM dual-pass and TDM can be considered two communication modes / operating modes for terminal devices. The mode adopted by the terminal device depends primarily on its capabilities. For example, a network device schedules a terminal device to perform uplink transmission on a certain frequency band. Assume that the frequency band resource size is 1 terabyte. If both user identities of the terminal device require more than 1 terabyte for uplink transmission, then the frequency band resources configured by the network device are insufficient. In this case, the terminal device performs uplink transmission using TDM.

[0079] Currently, the communication mode used by a terminal device is determined by the terminal device itself, and the network device is unaware of it. Consequently, when the network device calls the terminal device, the communication mode does not match the actual communication mode used by the terminal device, resulting in low communication performance for the terminal device. For example, due to limited radio frequency resources, the first user identity of the terminal device performs uplink transmission, while the second user identity does not. If the network device does not receive an uplink transmission from the second user identity for a long period of time, it may deem the terminal device's transmission abnormal and may release the terminal device's RRC connection, or the terminal device may request cell reestablishment. This process repeats, resulting in low communication performance for the terminal device.

[0080] In order to solve the above technical problems, the present invention provides a solution in which a terminal device can notify a network device of the communication mode it uses, so that the network device schedules the terminal device according to the communication mode actually used by the terminal device, thereby maximizing the communication performance of the terminal device.

[0081] The solution provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0082] In the embodiments of the present application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination end of the information is XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source end of the information is YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface. In other words, sending and receiving can be carried out between devices, for example, between a network device and a terminal device, or can be carried out within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, a line or an interface.

[0083] In the embodiments of this application, "when," "if," and "if" all indicate that the device will perform a corresponding action under certain objective circumstances. They do not limit the time, do not require the device to perform a judgment action when implemented, and do not imply any other limitations. Unless otherwise specified, "if" and "if" are interchangeable, and "when" and "under the circumstances" are interchangeable. "When" and "if" are interchangeable.

[0084] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0085] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plural" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. For example, A / B means: A or B. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0086] In the embodiments of this application, ordinal numbers such as "first" and "second" are used to distinguish multiple objects and are not used to define the size, content, order, timing, priority, or importance of multiple objects. For example, the first user identity and the second user identity refer to two different user identities, but do not indicate differences in content, priority, or importance between the two user identities.

[0087] The following takes the application of the communication method provided in the embodiment of the present application to the network architecture shown in Figure 1 as an example, and the following takes the application embodiment of the communication method provided by the network device and the terminal device as an example to introduce the communication method. The steps performed by the network device can be implemented by the RAN device itself, or by components in the RAN device (such as baseband chips, or other processing units or processor modules). For example, the network device can be the network device in Figure 1, such as the network device 110a, or it can be a chip (system) in the network device in Figure 1. The steps performed by the terminal device can be implemented by the terminal device itself, or by components in the terminal device (such as chips, processing units, or processor modules). The terminal device can be the terminal device shown in Figure 1, such as the terminal device 120a, or it can be a chip (system) in the terminal device in Figure 1.

[0088] Please refer to Figure 2, which is a flow chart of a communication method 200 provided in an embodiment of the present application. Figure 2 introduces the method from the perspective of interaction between a network device and a terminal device. It should be understood that the communication method 200 can also be implemented by other devices, such as a chip or communication device with communication functions. It should be noted that the embodiment of the present application only takes execution by a network device and a terminal device as an example, and is not limited to a network device and a terminal device. For example, the embodiment of the present application can also be executed by more terminal devices. When more terminal devices are involved, each of the more terminal devices executes the same process.

[0089] It should be noted that in the embodiments of the present application, the terminal device supports two user identities. For ease of description, the following example uses the terminal device supporting a first user identity and a second user identity. The first user identity can be understood as the user identity of the terminal device after the SIM1 card is installed, and the second user identity can be understood as the user identity of the terminal device after the SIM2 card is installed. In other possible embodiments, if the terminal device can support the installation of more than two SIM cards, the terminal device can also support more than two user identities, for example, the terminal device can support three or four user identities.

[0090] When the user identity of the terminal device is the first user identity, from the perspective of the network side, the terminal device can be understood as a user (from the perspective of the protocol, it is a terminal device, for example, called the first user); when the user identity of the terminal device is the second user identity, from the perspective of the network side, the terminal device can be understood as another user (for example, called the second user). The terminal device can be registered on the first network as the first user identity, and registered on the second network as the second user identity. In an embodiment of the present application, the terminal device supports one user identity, which can also be described as the terminal device having one user identity. Similarly, the terminal device supports two user identities, which can also be described as the terminal device having two user identities.

[0091] In the various embodiments of this application, "the terminal device as the first user identity" can be understood as "the first user identity of the terminal device" or "the terminal device with the first user identity". The three descriptions indicate the same content and are interchangeable. Similarly, "the terminal device as the second user identity" can be understood as "the terminal device with the second user identity" or "the second user identity of the terminal device". The three descriptions indicate the same content and are interchangeable.

[0092] In addition, it should be noted that the first user identity and the second user identity access the same network device, or the first user identity and the second user identity reside in the same cell, or the first user identity and the second user identity access the same cell. When the terminal device is in the RRC connected state, the RRC idle state or the RRC inactive state, the first user identity and the second user identity are both in the same cell. Taking the example that the first user identity and the second user identity are both in the first cell, the terminal device communicates with the network device in the first cell as the first user identity, and the terminal device also communicates with the network device in the first cell as the second user identity.

[0093] As shown in FIG2 , the process of the communication method 200 includes the following steps.

[0094] S201: A terminal device sends first information to a network device, where the first information is used to instruct the terminal device to send information in a first manner and in a first frequency band. Correspondingly, the network device receives the first information from the terminal device.

[0095] The terminal device supports a first user identity and a second user identity, and the first user identity and the second user identity belong to the same mobile operator. The first user identity and the second user identity may belong to the same standard, for example, the first user identity and the second user identity both belong to the LTE standard, and the network device may be an eNB; or the first user identity and the second user identity may belong to different standards, for example, the first user identity belongs to the LTE standard, the second user identity belongs to the NR standard, and the network device may be a gNB.

[0096] The first frequency band may be a frequency band supported by the terminal device. The frequency band may also be referred to as a frequency band, and each frequency band corresponds to a frequency range. Each frequency band in each frequency band combination may include one or more continuous or non-continuous carriers. In an embodiment of the present application, a frequency band may also be a frequency / frequency point. The frequency band supported by the terminal device is determined by the capabilities of the terminal device. Depending on the capabilities of the terminal device, the frequency band supported by the terminal device may also be different. The capabilities of the terminal device include the frequency bands supported by the terminal device, frequency band combinations (band combination, BC), etc. The frequency band combination can be used to express the carrier aggregation (CA) and dual connectivity (DC) capabilities supported by the UE. CA refers to providing services to the terminal device through multiple carriers at the same time, and providing services to the terminal device at the same time by aggregating multiple CCs. Due to the large number of frequency bands and frequency band combinations defined by the protocol, in order to enable the network device to schedule the terminal device according to the capabilities of the terminal device, the terminal device may report frequency band capabilities, frequency band combination capabilities, etc.

[0097] The first information is used to instruct the terminal device to transmit information in the first frequency band in the first manner. It can also be understood that the first information can be used to indicate that the terminal device expects the network device to schedule the terminal device to transmit information in the first frequency band in the first manner; alternatively, the first information can indicate that the communication mode / operating mode of the terminal device is the first mode. The first mode is the TDM mode or the DSDA mode. Based on the first information, the network device can determine that the terminal device adopts the first mode, thereby scheduling the terminal device according to the first mode to improve the communication performance of the terminal device.

[0098] The first frequency band may be a frequency band within a frequency band combination. In this case, the first information used to instruct the terminal device to send information in the first frequency band in a first manner includes: the first information is used to indicate the communication method used by the terminal device to send information on each frequency band within the frequency band combination. For example, the first information instructs the terminal device to send information in the first frequency band combination in at least one manner, wherein the at least one manner corresponds to the frequency bands included in the first frequency band combination, and the first frequency band combination includes the first frequency band. Accordingly, the network device schedules the terminal device in a corresponding communication method in a certain frequency band to maximize the communication performance of the terminal device.

[0099] In a possible scenario, the uplink transmission of one user identity may affect the downlink transmission of another user identity. For example, two user identities of a terminal device share the same radio frequency channel, and the uplink radio frequency switching of the first user identity may interrupt the downlink transmission of the second user identity. In order to reduce the impact that the uplink transmission of one user identity may have on the downlink transmission of another user identity, the first information may also include a first indication information to indicate whether the downlink transmission of the second user identity will be interrupted when the first user identity performs uplink radio frequency switching / uplink transmission. Accordingly, the network device schedules the two user identities of the terminal device according to the first indication information, and when scheduling the first user identity to perform uplink radio frequency switching / uplink transmission, the second user identity of the terminal device is not scheduled to perform downlink transmission. The first indication information indicating whether the downlink transmission of the second user identity will be interrupted when the first user identity performs uplink radio frequency switching / uplink transmission includes: the first indication information indicates whether the downlink transmission of the second user identity on frequency band N will be interrupted during the period when the first user identity performs uplink radio frequency switching.

[0100] Furthermore, given that radio frequency switching requires a certain amount of time, to allow sufficient processing time for the terminal device's two user identities to switch, the first information may also include first time information, which may indicate the required interval between the two user identity switches of the terminal device. Accordingly, the network device schedules the terminal device based on the first time information, ensuring that the interval between the two user identity switches is at least the duration indicated by the first time information. Optionally, if the first information does not include the first time information, it may be assumed that no interval is required between the two user identity switches.

[0101] In a possible scenario, resources are limited. If the network device independently decides to allocate resources to the two user identities of a terminal device, it may not be able to meet the actual needs of a user identity. For example, if the terminal device's first user identity is used for voice services, and the terminal device's second user identity is used for data services, if the network device prioritizes the first user identity and allocates more resources, it may cause the second user identity's data services to be interrupted, or even prevent the second user identity from being scheduled.

[0102] To this end, in an embodiment of the present application, the terminal device may also send a third message to the network device to assist the network device in reasonably allocating resources for the two user identities of the terminal device so as to meet the actual scheduling needs of the two user identities as much as possible.

[0103] For example, the third information may indicate the priority / scheduling priority of the two user identities. Accordingly, the network device allocates resources to the two user identities based on the third information, giving priority to the user identity with a higher priority, so as to meet the actual scheduling needs of the two user identities as much as possible.

[0104] For another example, the third information may indicate the time domain resource requirements of the two user identities. For example, the third information may indicate the time slot ratios required by the first user identity and the second user identity, respectively. For example, the third information may indicate that the time slot ratio required by the first user identity is 30%, and the time slot ratio required by the second user identity is 50%. Accordingly, the network device allocates resources to the two user identities based on the third information, thereby meeting the actual scheduling needs of the two user identities.

[0105] It should be noted that the third information and the first information can be carried in the same signaling or in different signalings, and this embodiment of the present application does not limit this.

[0106] In an embodiment of the present application, the terminal device may execute S201 as the first user and / or the second user. That is, the terminal device may send the first information to the network device as the first user, or send the first information to the network device as the second user; or the terminal device may send the first information to the network device as the first user and the second user. The terminal device may send the first information during the registration process with the network device, or may send the first information to the network device through dynamic signaling when entering the RRC connected state.

[0107] Please refer to Figure 3A, which is a flow chart of a terminal device sending first information to a network device according to an embodiment of the present application. Figure 3A takes the example of a terminal device sending first information during the registration process with a network device.

[0108] S301a. The network device sends an identifier (ID) of a first user identity to the terminal device.

[0109] The terminal device requests registration from the network device as the first user. The network device responds to the registration request. If the first user successfully registers with the network device, the network device feeds back the ID of the first user to the terminal device.

[0110] S302a: The terminal device sends capability information of the terminal device to the network device as the first user, where the capability information includes first information.

[0111] Accordingly, the network device receives the capability information of the terminal device and can determine the first information from the capability information of the terminal device.

[0112] The content indicated by the first information can be used as a capability of the terminal device. Accordingly, the first information can be included in the capability information of the terminal device. For example, the first information is included in the frequency band (per band) capability information of the terminal device as a newly added element in the capability information element "RF-Parameters->supportedBandListNR->BandNR", as indicated in bold in the following code.

[0113] When the first information also includes the first indication information, accordingly, "RF-Parameters->supportedBandListNR->BandNR" may be:

[0114] Among them, "uplinkTxSwitchingPeriod" represents the first time information, and "uplinkTxSwitching-DL-Interruption bitmap" represents the first indication information, which is implemented in the form of a bitmap bitmap, and one bit in the bitmap corresponds to one carrier / frequency band. Among them, the corresponding bit in the bitmap is "1", indicating that the uplink transmission of the first user identity will cause the downlink transmission of the second user identity on the frequency band corresponding to the bit to be interrupted; the corresponding bit in the bitmap is "0", indicating that the uplink transmission of the first user identity will not cause the downlink transmission of the second user identity on the frequency band corresponding to the bit to be interrupted. Alternatively, the corresponding bit in the bitmap is "0", indicating that the uplink transmission of the first user identity will cause the downlink transmission of the second user identity on the frequency band corresponding to the bit to be interrupted; the corresponding bit in the bitmap is "1", indicating that the uplink transmission of the first user identity will not cause the downlink transmission of the second user identity on the frequency band corresponding to the bit to be interrupted.

[0115] When the first information and the third information are carried in the same signaling, the third information can also be included in the capability information of the terminal device. Taking the third information indicating the priority of two user identities as an example, "RF-Parameters->supportedBandListNR->BandNR" can be:

[0116] Taking the third information indicating the priority of two user identities as an example, "RF-Parameters->supportedBandListNR->BandNR" can be:

[0117] S303a: The network device sends the ID of the second user identity to the terminal device.

[0118] The terminal device requests registration from the network device as the second user. The network device responds to the registration request. If the second user successfully registers with the network device, the network device feeds back the ID of the second user to the terminal device.

[0119] S304a: The terminal device sends capability information of the terminal device to the network device as the second user, where the capability information includes the first information.

[0120] The terminal device sending the first information to the network device as the second user can refer to the aforementioned terminal device sending the first information to the network device as the first user. For details, please refer to the relevant content in the aforementioned S302a, which will not be repeated here.

[0121] S305a. The terminal device sends the ID of the second user identity to the network device as the first user identity.

[0122] The terminal device sends the ID of the second user identity to the network device as the first user identity, so that the network device determines that the first user identity and the second user identity are two user identities of the same terminal device.

[0123] It should be noted that when the capability information of the terminal device in S302a includes the first information, the capability information of the terminal device in S304a may or may not include the first information. When the capability information of the terminal device in S304a includes the first information, the capability information of the terminal device in S302a may or may not include the first information. Figure 3A takes the example that the capability information of the terminal devices in S302a and S304a both include the first information. S305a is executed after S301a and S303a, and the execution order of S305a, S302a, and S304a is not limited.

[0124] Please refer to Figure 3B, which is another flow diagram of a terminal device sending first information to a network device according to an embodiment of the present application. Figure 3B takes the example of a terminal device entering an RRC connected state and sending the first information to the network device via dynamic signaling.

[0125] S301b: The terminal device sends a registration request to the network device as the first user. Correspondingly, the network device receives the registration request.

[0126] The registration request is used to request the first user identity to register with the network device. The difference from S301a is that the registration request does not include the first information.

[0127] S302b: The network device sends the ID of the first user identity to the terminal device. This is the same as S302a and will not be repeated here.

[0128] S303b: The terminal device sends a registration request to the network device as the second user. Correspondingly, the network device receives the registration request.

[0129] The registration request is used to request the second user identity to register with the network device. The difference from S303a is that the registration request does not include the first information.

[0130] S304b: The network device sends the ID of the second user identity to the terminal device. This is the same as S304a and will not be repeated here.

[0131] S305b: The terminal device sends the ID of the second user identity to the network device as the first user identity. This is the same as S305a and will not be repeated here.

[0132] The terminal device sends the ID of the second user identity to the network device as the first user identity, so that the network device determines that the first user identity and the second user identity are two user identities of the same terminal device.

[0133] S306b. After the terminal device establishes an RRC connection state as the first user, it sends the first information to the network device.

[0134] The first information may be carried in an RRC message or a UAI message. Taking the first information carried in a UAI message as an example, the UAI message may include a band and a corresponding working mode. Accordingly, there are:

[0135] S307b. After the terminal device establishes an RRC connection state as the second user, it sends the first information to the network device.

[0136] The implementation manner in which the terminal device sends the first information as the second user is the same as the implementation manner in which the terminal device discovers the first information as the first user, and will not be repeated here.

[0137] It should be noted that either S306b or S307b can be selected for execution, or both S306b and S307b can be executed. FIG3A takes the execution of both S306b and S307b as an example.

[0138] Optionally, in the process of FIG3B , after receiving the first information, the network device may feed back a prohibition timer to the terminal device, and the terminal device will no longer send the first information before the timer prohibits, thereby avoiding the terminal device from frequently reporting the first information.

[0139] S202: The network device sends second information to the terminal device. Correspondingly, the terminal device receives the second information from the network device.

[0140] The network device receives the first information and can schedule the terminal device according to the first information. For example, the network device can send second information to the terminal device, where the second information includes scheduling information of the terminal device. For example, the network device determines from the first information that the terminal device sends information in a first manner on a first frequency band, and then the network device schedules the terminal device to send uplink information in the first manner. The uplink information can be a physical uplink shared channel (PUSCH), a physical uplink control channel (PUCCH), SRS, etc.

[0141] The second information may be downlink control information (DCI), which carries scheduling information of the terminal device. The scheduling information of the terminal device includes information such as time domain resources and frequency domain resources allocated by the network device to the terminal device. Taking the first mode as the TDM mode as an example, the time domain resources allocated by the network device to the two user identities of the terminal device do not overlap. When the first mode is the DSDA mode, the time domain resources allocated by the network device to the two user identities of the terminal device may overlap, so that the communication delay of the two user identities can be minimized.

[0142] S203. The terminal device sends uplink information on the first frequency band.

[0143] The terminal device sends uplink information on the first frequency band according to the second information.

[0144] In the communication method 200 described above, the terminal device notifies the network device of the communication mode to be used, so that the network device schedules the terminal device based on the terminal device's communication mode. Compared to a scenario where the network device is unaware of the terminal device's communication mode and independently schedules the terminal device, this method reduces the impact on communication between the two user identities of the terminal device and improves the terminal device's communication performance.

[0145] Considering that two user identities belong to the same terminal device, to reduce power consumption, it is proposed that one user identity can be used to proxy paging messages for the other. However, in some scenarios, the terminal device may move to a cell that does not support proxy paging messages for one user identity. In this case, if one user identity is still used to proxy paging messages for the other user identity, the other user identity will never receive paging messages and will be unable to carry out normal business.

[0146] If a cell supports receiving paging messages through one user identity as a proxy for another user identity, it can be considered that the cell supports paging sharing and can also be called a paging sharing cell. In the embodiment of the present application, when the terminal device moves to a cell that does not support paging sharing, paging sharing is canceled or paging sharing is not effective. "Canceling paging sharing or paging sharing not taking effect" actually means canceling the receipt of paging messages by one user identity as a proxy for another user identity, and restoring the receipt of paging messages by each of the two user identities. In this way, some user identities can be prevented from missing paging messages.

[0147] Please refer to Figure 4, which is a flowchart of a communication method 400 provided in an embodiment of the present application. Figure 4 describes the method from the perspective of interaction between a network device and a terminal device. The terminal device supports two user identities. The following example uses the terminal device supporting a first user identity and a second user identity. Furthermore, the terminal device is configured to allow the first user identity to act as a proxy for the second user identity to receive paging messages. As shown in Figure 4, the process of communication method 400 includes the following steps.

[0148] S401. The terminal device reselects from the first cell to the second cell.

[0149] S402: The terminal device receives a paging message as a first user and a second user.

[0150] The second cell is the cell in which the terminal device is currently stationed. When the terminal device reselects from the first cell to the second cell, paging sharing / proxy may be canceled by default or paging sharing may be disabled by default. For example, when the terminal device reselects from the first cell to the second cell, the terminal device receives paging messages as the first user and the second user. The terminal device receives paging messages as the first user and the second user, that is, the terminal device receives paging messages through the first user and the second user.

[0151] Alternatively, when a terminal device reselects from a first cell to a second cell, it may determine whether the second cell supports the terminal device receiving paging messages as a first user on behalf of a second user. If the second cell does not support the terminal device receiving paging messages as a first user on behalf of a second user, the terminal device reselects to the second cell and receives paging messages as the first user and the second user. If the second cell supports the terminal device receiving paging messages as a first user on behalf of a second user, the terminal device reselects to the second cell and receives paging messages as a first user on behalf of the second user, thereby reducing energy consumption of the terminal device.

[0152] It should be noted that when the terminal device reselects from the first cell to the second cell and enters the RRC connection state again, it can negotiate with the network device to determine whether to enable paging sharing, or determine whether to receive paging messages as the first user on behalf of the second user, so as to save the power consumption of the terminal device as much as possible.

[0153] Optionally, before S402, the network device may indicate to the terminal device cells that support paging sharing or cells that do not support paging sharing. For example, before S402, S400 may be executed. Since S400 is not required, it is indicated by a dotted line in FIG4.

[0154] S400: The network device sends second indication information to the terminal device. The second indication information may indicate whether the second cell supports the first user identity to act as a proxy for the second user identity to receive a paging message.

[0155] The second indication information may indicate cells that support paging sharing or cells that do not support paging sharing. For example, the second indication information indicates a cell list, and all cells in the list support paging sharing. If the list does not include the second cell, then the second cell does not support paging sharing. For another example, the second indication information indicates a cell list, and all cells in the list do not support paging sharing. If the list includes the second cell, then the second cell does not support paging sharing.

[0156] Optionally, the second indication information may be carried in a system message.

[0157] Please refer to Figure 5, which is a schematic diagram of a flow chart of a communication method 500 provided in an embodiment of the present application. Figure 5 describes the method from the perspective of interaction between a network device and a terminal device. The terminal device supports two user identities. The following example uses the terminal device supporting a first user identity and a second user identity. Furthermore, the terminal device is configured to allow the first user identity to act as a proxy for the second user identity to receive paging messages. As shown in Figure 5, the flow of communication method 500 includes the following steps.

[0158] S501. The terminal device reselects from the first cell to the second cell.

[0159] S502: The terminal device receives a paging message as a first user and a second user.

[0160] In one scenario, after the terminal device reselects a cell, the two user identities may not be in the same cell, but the cells where the two user identities are located belong to the same paging range. The paging range includes TA or RA. The two cells belong to the same paging range, which can be replaced by the two cells belonging to the same TA / RA list. For example, after the terminal device switches from the first cell to the second cell, the first user identity of the terminal device is in the first cell, and the second user identity is in the second cell, but the first cell and the second cell belong to the same TA / RA list. In this scenario, if one user identity is used to proxy another user identity to receive paging, the cell-level system message may be lost. For example, for example, the system message of the cell where the second user identity is located (such as the first cell) has changed, but the network device sends a paging message and the terminal device receives it as a proxy for the first user identity, and the system message of the cell where the second user identity is located will be missed.

[0161] Therefore, after the terminal device reselects a cell, if the two user identities of the terminal device are not in the same cell and the cells where the two user identities are located belong to the same TA / RA list, the terminal device cancels paging sharing / proxy and receives paging messages as the first user identity and the second user identity. After the terminal device enters the RRC connection state again, it can negotiate with the network device to determine whether to enable paging sharing, or determine whether to use the first user identity to proxy the second user identity to receive paging messages, so as to save the power consumption of the terminal device as much as possible. Optionally, the terminal device still uses the first user identity to proxy the second user identity to receive paging messages. However, the second user identity receives the paging message forwarded from the first user identity, and the second user identity updates the system message.

[0162] In another scenario, after the terminal device reselects a cell, the two user identities may not be in the same cell, and the cells where the two user identities are located do not belong to the same TA / RA list. In this case, if one user identity is used to receive a paging message on behalf of another user identity, the other user identity will lose the paging message. Therefore, in this case, the terminal device also cancels paging sharing / proxy and receives paging messages as the first user identity and the second user identity. After the terminal device enters the RRC connection state again, it can negotiate with the network device to determine whether to enable paging sharing, or determine whether to use the first user identity to receive the paging message on behalf of the second user identity, so as to save the power consumption of the terminal device as much as possible.
