[0041] The network-side device 12 may include an access network device or a core network device, wherein the access network device may also be referred to as a radio access network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP), or a wireless fidelity (WiFi) node. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home evolved Node B (home evolved Node B), Transmit / Receive Point (TRP) or other appropriate terms in the relevant field. As long as the same technical effect is achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0042] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (MME), access mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), policy and charging rules function unit (PCRF), edge application service discovery function (EASDF), unified data management (UDM), unified data repository (UDR), home user server (HSS), centralized network configuration (CNC), network storage function (NRF), network exposure function (NEF), local NEF (L-NEF), binding support function (BSF), application function ( It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0043] In some embodiments, the terminal and the network-side device can refer to FIG2 , where the terminal includes a main communication module and an extremely low-power communication module, and the network-side device includes a main communication module and an extremely low-power communication module. The main communication module and the extremely low-power communication module can communicate with each other, and the extremely low-power communication module of the terminal can communicate with the extremely low-power communication module of the network-side device. It should be noted that FIG2 is only an example. For example, in some embodiments, the main communication module of the terminal can communicate with the main communication module of the network-side device. In some embodiments, the extremely low-power communication module of the terminal can communicate with the main communication module of the network-side device.

[0044] In some embodiments, the main communication module can support traditional communication modes (such as 4G, 5G, 6G, etc.) and communication technologies for mobile broadband (MBB) or enhanced mobile broadband (eMBB) scenarios; for example: 5G NR technology that supports orthogonal frequency division multiplex (OFDM) communication, including uplink and / or downlink communication.

[0045] In some embodiments, the extremely low power communication module can support extremely low power communication (such as supporting signal transmission by backscatter) or support low power reception, for example: the extremely low power communication module includes a low power receiving module, such as a low power wake-up receiver. For the signal transmission method by backscatter, the excitation source signal can be generated by the terminal with the extremely low power communication module itself or by other devices. For example: in the case where the extremely low power communication module is a backscatter communication module, the main communication module will naturally stimulate the extremely low power communication module when sending the signal, so the additional backscatter signal generated has almost no additional overhead.

[0046] In some embodiments, the extremely low power communication may include at least one of the following:

[0047] Supports backscatter communication for energy harvesting;

[0048] Support powered backscatter communications;

[0049] Low power reception.

[0050] For example, an ultra-low power communication module can support energy harvesting, including but not limited to harvesting energy from light, solar energy, wireless signals, etc.

[0051] In addition, the excitation source signal of the backscatter communication may be generated by the terminal having the extremely low power consumption communication module itself or by other devices.

[0052] In some embodiments, extremely low power communication may refer to communication whose power consumption is significantly lower than that of the main communication module. For example, communication of a communication module whose power consumption is generally tens of microwatts to hundreds of microwatts is extremely low power communication, while the power consumption of the main communication module is generally tens of milliwatts to thousands of milliwatts, and the cost of the extremely low power communication module is also significantly lower than that of the main communication module.

[0053] Backscatter communication is the most representative technology for ultra-low-power communication. In principle, backscatter communication devices adjust their internal impedance to control the circuit's reflection coefficient, thereby varying the amplitude, frequency, and phase of RF signals from other devices or the environment, achieving signal modulation. A typical backscatter communication hardware module, as shown in Figure 3, includes: an antenna unit, an energy harvesting module or power supply module, a microcontroller, a signal receiving module, a channel coding and modulation module, and a memory or sensor module. The signal receiving module is responsible for receiving downlink signals sent to the backscatter device by network-side devices or card readers. Its architecture and technology can reuse low-power wake-up receiver technology already defined in the protocol or subsequently defined. Because backscatter communication does not actively generate RF signals, its power consumption is extremely low, typically ranging from tens to hundreds of microwatts. The energy harvesting module can harvest environmental energy, such as RF signals, light, and heat, to power the modulation, demodulation, and reflection of the signal, eliminating the need for a dedicated power source such as a battery. Alternatively, it can be powered by a small power supply module, such as a button cell battery, thus reducing the required power signal strength. In addition to the typical building blocks mentioned above, backscatter communication technology can integrate low-power amplifier modules to improve receiving sensitivity and backscatter signal power.

[0054] It should be noted that in the embodiment of the present application, backscatter communication is only an example of extremely low power communication. In the embodiment of the present application, there is no limitation on extremely low power communication. For example, it can be extremely low power communication defined in the protocol, such as communication of a communication module with power consumption of tens to hundreds of microwatts.

[0055] The following describes in detail a communication method, device, and terminal provided by the embodiments of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0056] Please refer to FIG4 , which is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG4 , the method includes the following steps:

[0057] Step 401: The terminal performs communication transmission based on the first communication module;

[0058] Step 402: The terminal performs communication transmission of the second communication module based on a target protocol layer, where the target protocol layer includes at least one of the following:

[0059] a protocol layer of the second communication module;

[0060] a protocol layer of the first communication module;

[0061] The first protocol layer is a protocol layer outside the first communication module and the second communication module.

[0062] In some embodiments, the first communication module may be one of an extremely low-power communication module and a main communication module, and the second communication module may be the other of the extremely low-power communication module and the main communication module. For example, the first communication module may be the main communication module and the second communication module may be the extremely low-power communication module, or the second communication module may be the main communication module and the first communication module may be the extremely low-power communication module. The extremely low-power communication module is a module that supports extremely low-power communication, and the main communication module consumes more power than the extremely low-power communication module.

[0063] In some embodiments, the first communication module and the second communication module are two different ultra-low power communication modules. For example, the first communication module and the second communication module are communication modules capable of transmitting signals in a backscattered manner and a communication module capable of transmitting signals in an actively generated carrier wave manner. For example, the first device is an IoT terminal capable of transmitting signals in two communication modes, such as an IoT terminal capable of transmitting signals in both a backscattered manner and an actively generated carrier wave manner.

[0064] In some implementations, the first communication module and the second communication module may be two completely independent communication modules, or the first communication module and the second communication module may share some or all module contents.

[0065] The above-mentioned terminal performing communication transmission based on the first communication module means that the terminal performs communication transmission based on the protocol layer of the first communication module, wherein the communication transmission includes at least one of sending and receiving.

[0066] The terminal performing communication transmission of the second communication module based on the target protocol layer can be understood as that the protocol layer used in the communication transmission process through the second communication module is the target protocol layer. The communication transmission includes at least one of sending and receiving through the second communication module.

[0067] The first protocol layer is a protocol layer outside the first communication module and the second communication module, which means that the above-mentioned first protocol layer does not belong to the first communication module or the second communication module. The protocol layer can be an additional protocol layer added outside the first communication module and the second communication module, or it can be an existing protocol layer of the terminal.

[0068] The protocol layer of the first communication module included in the above-mentioned target protocol layer may be a partial protocol layer or all protocol layers of the first communication module, wherein, in the case of a partial protocol layer, step 402 may be to perform communication transmission of the second communication module based on the partial protocol layer of the first communication module and the protocol layer of the second communication module; in the case of all protocol layers, step 402 may be to perform communication transmission of the second communication module based on all protocol layers of the first communication module and the protocol layer of the second communication module, and to perform communication transmission of the second communication module based on all protocol layers of the first communication module.

[0069] The above step 402 may include:

[0070] The terminal transmits communication based on the protocol layer of the first communication module and the protocol layer of the second communication module; or,

[0071] The terminal transmits communication based on the first protocol layer and the second communication module of the protocol layer of the first communication module; or,

[0072] The terminal transmits communication based on the first protocol layer and the second communication module's protocol layer; or,

[0073] The terminal transmits communication based on the protocol layer of the first communication module, the first protocol layer and the protocol layer of the second communication module; or

[0074] The terminal transmits communication via the second communication module based on the protocol layer of the first communication module; or

[0075] The terminal performs communication transmission of the second communication module based on the protocol layer of the second communication module.

[0076] In some implementations, the terminal performing communication transmission of the second communication module based on the target protocol layer may be performing transmission processing on the data to be sent based on the target protocol layer.

[0077] In some implementations, the terminal performing communication transmission of the second communication module based on the target protocol layer may be performing data reception-related processing based on the target protocol layer.

[0078] In some embodiments, the protocol layer of the first communication module may also be referred to as the protocol layer or functional layer included in the protocol stack of the first communication module, and the protocol of the second communication module may also be referred to as the protocol layer or functional layer included in the protocol stack of the second communication module.

[0079] It should be noted that step 401 and step 402 may be executed simultaneously or sequentially. FIG4 illustrates an example in which step 401 is executed first and then step 402 .

[0080] In the embodiment of the present application, the above steps enable parallel transmission through the two communication modules, thereby improving the transmission performance of the terminal, such as improving the reliability and rate of terminal transmission, and reducing the energy consumption of the terminal because the same protocol layer can be shared. In addition, because the above-mentioned target protocol layer is used when communicating and transmitting through the second communication module, the second communication module does not need to have all the protocol layers required for communication and transmission, thereby reducing the complexity of the second communication module.

[0081] As an optional implementation manner, the protocol layer of the first communication module includes at least one of the following:

[0082] Application layer, Radio Resource Control (RRC) layer, Service Data Adaptation Protocol (SDAP) layer, Packet Data Convergence Control (PDCP) layer, Radio Link Control (RLC) layer, Medium Access Control (MAC) layer, and Physical (PHY) layer.

[0133] The aforementioned forming of the content submitted by the upper layer into an SDAP PDU and delivering it to the lower layer may include forming an SDAP PDU from the PDU / SDAP SDU submitted by the upper layer and delivering it to the lower layer; the aforementioned forming of the content submitted by the lower layer into a PDU or SDAP SDU and delivering it to the upper layer may include decomposing the SDAP PDU submitted by the lower layer into an upper-layer PDU / SDAP SDU and delivering it to the upper layer. When delivering the PDU / SDU, the PDU / SDU is mapped to the corresponding radio bearer based on QoS-related information such as the Quality of Service (QoS) ID and QoS requirements, or PDUs / SDUs with the same QoS ID or QoS requirements belong to the same QoS flow.

[0134] The sixth function includes at least one of the following:

[0135] Generate user plane data and deliver the PDU corresponding to the user plane data to the lower layer; generate control plane data and deliver the PDU corresponding to the control plane data to the lower layer; restore the data delivered by the lower layer to user plane data; restore the data delivered by the lower layer to control plane data, establish RRC connection; establish secure communication; manage RRC state; perform security functions; manage mobility; configure measurement and report measurement; detect radio link failure and reestablish connection; process target services; manage device state; configure system message; generate system message; broadcast system message.

[0136] Among them, the above security functions may include key management and password management.

[0137] The above mobility management may include handover, context transmission, cell selection and reselection.

[0138] The above-mentioned processing target business can be processing specific business, such as inventory, positioning, control, perception and other businesses of IoT devices.

[0139] The above-mentioned device status management can be IoT device status management, such as enable, disable, energy-related status (such as charging, low battery), etc.

[0140] In the above implementation manner, the protocol layer is used to implement at least one of the above functions, which can be understood as, in some implementation manners, some protocol layers can implement one or more functions, for example: the PHY layer of the second communication module is responsible for the first and second functions, and the MAC layer is responsible for the third to sixth functions.

[0141] In the above implementation, one or more protocol layers can be flexibly configured for the second communication module, and one protocol layer can implement one or more functions, thereby further reducing the complexity of the protocol stack of the second communication module.

[0142] As an optional implementation manner, the terminal processes at least one of the following based on the first collaboration layer:

[0143] Merging the content submitted by the lower layer of the first communication module and the content submitted by the lower layer of the second communication module;

[0144] Splitting the content acquired by the first collaborative layer of the first communication module, and delivering the split content to the lower layer of the first communication module and the lower layer of the second communication module respectively;

[0145] performing data processing on the content submitted by the lower layer of the second communication module according to the content submitted by the lower layer of the first communication module;

[0146] performing data processing on the content submitted by the lower layer of the first communication module according to the content submitted by the lower layer of the second communication module;

[0147] performing a device control operation according to at least one of the content submitted by the lower layer of the first communication module and the content submitted by the lower layer of the second communication module;

[0148] The first collaboration layer is a protocol layer in the protocol layers of the first communication module, or the first collaboration layer is a protocol layer in the protocol layers of the second communication module, or the first collaboration layer is the first protocol layer;

[0149] The lower layer is a protocol layer next to the first collaborative layer.

[0150] The terminal processing the at least one item based on the first collaborative layer may include: during a communication transmission process of the second communication module based on the target protocol layer or during a communication transmission process based on the first communication module, the terminal processing the at least one item based on the first collaborative layer. That is, the terminal performing at least one operation in at least one of step 401 and step 402 based on the first collaborative layer.

[0151] In some embodiments, the above-mentioned terminal may also perform processing based on the first collaborative layer other than steps 401 and 402, such as performing device control operations based on at least one of the content submitted by the lower layer of the first communication module and the content submitted by the lower layer of the second communication module.

[0152] The first collaboration layer is a protocol layer that is used to process data of the first communication module and also to provide services for data of the second communication module. That is, the first collaboration layer needs to have at least one of the above functions in addition to its own functions.

[0153] In some embodiments, the above content includes at least one of the following:

[0154] SDU, PDU, raw data, packet header, signaling.

[0155] For example, the above-mentioned first collaborative layer is used to receive the PDU of the upper-layer entity, split and package it into two SDUs of the lower-layer entities. The lower-layer SDU may carry at least part of the data information of the upper-layer PDU, or may only carry control information; or, receive PDUs submitted from two lower-layer entities and submit a complete SDU to the upper-layer entity.

[0156] In some embodiments, the data processing includes at least one of the following:

[0157] Split, merge, discard, encrypt, and decrypt.

[0158] For example, the first coordination layer is used to perform specified operations such as splitting, merging, discarding, encrypting, and decrypting on a PDU submitted by another lower-layer entity according to the PDU or PDU Header submitted by another lower-layer entity.

[0159] In some embodiments, the device control operation includes at least one of the following:

[0160] Switch the RF front end, wake up the communication module, switch the device status, send specified signals, and receive specified signals.

[0161] For example: the above-mentioned first collaborative layer is used to perform specified operations based on the PDU or PDU Header submitted by at least one lower-layer entity, such as switching the RF front-end, waking up a module, switching the status of the device, sending or receiving a specified signal, wherein the status of the above-mentioned switching device includes but is not limited to the RRC status and the connection management (CM) status.

[0162] In the above embodiment, the above-mentioned first collaborative layer can be the lowest layer of the protocol layer of the first communication module used in the data transmission process of the second communication module. If the protocol layer of the first communication module used in the data transmission process of the second communication module is the RRC layer, SDAP layer, PDCP layer, RLC layer and MAC layer, then the above-mentioned first collaborative layer is the MAC; if the protocol layer of the first communication module used in the data transmission process of the second communication module is the RRC layer, SDAP layer, PDCP layer and RLC layer, then the above-mentioned first collaborative layer is the RLC layer; if the protocol layer of the first communication module used in the data transmission process of the second communication module is the RRC layer, SDAP layer and PDCP layer, then the above-mentioned first collaborative layer is the PDCP layer; if the protocol layer of the first communication module used in the data transmission process of the second communication module is the RRC layer and SDAP layer, then the above-mentioned first collaborative layer is the SDAP layer; if the protocol layer of the first communication module used in the data transmission process of the second communication module is the RRC layer, then the above-mentioned first collaborative layer is the RRC layer.

[0163] In some implementations, the first collaborative layer may be a protocol layer other than the lowest layer among the protocol layers of the first communication module used in the data transmission process of the second communication module.

[0164] The first collaboration layer may be the highest layer among the protocol layers of the first communication module, or may be another protocol layer except the highest layer among the protocol layers of the first communication module.

[0165] The high-layer entity of the first protocol layer may belong to the first communication module or the second communication module, or may be a common module belonging to neither.

[0166] In the above implementation, the integration and collaboration of the first communication module and the second communication module are achieved through the above first collaboration layer, so as to reduce the complexity of the second communication module.

[0167] It should be noted that, in the embodiments of the present application, the protocol layer may also be referred to as a protocol layer entity, a functional layer, or a functional layer entity. In the embodiments of the present application, a protocol layer may have one or more entities. For example, in the case of an ultra-reliable and low-latency communications (URLLC) service, the PDCP layer may have two entities, and the extra entity is used for duplicate transmission. For another example, if a protocol layer is unique in a terminal, the entity may not be reflected in the description of the protocol layer.

[0168] In the above implementation, the functional equivalence of each layer of the first communication module and the second communication module can be achieved. For example, the traditional protocol stack design can be followed, with six functional layers including the PHY layer, the MAC layer, the PDCP layer, the SDAP layer, and the RRC / application layer, which are responsible for the above-mentioned first function, second function, third function, fourth function, fifth function, and sixth function respectively. In order to achieve fusion and collaboration, the first collaboration layer (a high-level entity of one of the communication modules) processes the data submitted from the module and the low-level entity of the other module, and submits data to the module and the low-level entity of the other module. Below the collaboration layer, the functional layers of the two communication modules work independently, while the fusion of data and information exchange occur on the first collaboration layer, thereby reducing the complexity of the second communication module.

[0169] The protocol architecture in the above implementation may be referred to as a master-slave mapping architecture.

[0170] For ease of explanation, the embodiments of the present application are described in the case where both the first communication module and the second communication module have only one protocol stack. However, in some embodiments, the first communication module or the second communication module may have more than one protocol stack in certain circumstances, such as when supporting multiple frequency bands.

[0171] Taking the above-mentioned first collaborative layer as the MAC layer of the first communication module as an example, as shown in Figure 5, the physical layers of the first communication module and the second communication module are independent, and the MAC layer entity of the first communication module is responsible for merging or splitting the data stream, submitting data to the physical layers of the two modules respectively, or receiving data submitted from the physical layers of the two modules.

[0172] Taking the above-mentioned first collaborative layer as the application layer or RRC layer of the first communication module as an example, as shown in Figure 6, the layers below the SDAP layer of the first communication module and the second communication module are independent, and the application layer of the main communication module is responsible for merging or splitting data streams.

[0173] The entity responsible for splitting or merging data streams is the entity that actually performs operations on the data. However, the entity responsible for execution and the entity responsible for logic may not be the same. For example, the operations performed by the MAC layer are informed by a higher layer. For example, the data splitting or merging method is determined at the PDCP layer, and the PDCP tags the data or informs the MAC layer of the splitting or merging method or principle for execution. If the execution entity and the logical entity are not the same entity, the logical entity can be managed by a higher layer or by one of two equivalent entities between different modules.

[0174] The first coordination layer may also be implemented by an entity of any layer between the MAC layer or the RRC layer application layer, such as the RLC layer in FIG7 .

[0175] In the above embodiment, the terminal can have two communication modules that can be used for multiple purposes. For example, the second communication module can be used as a long-term standby module, and the first communication module can be enabled only in high-speed, high-power consumption scenarios; the two communication modules can also be enabled at the same time to increase the communication rate, and through the above-mentioned first collaborative layer, data from different modules can be mapped to the appropriate functional layer for processing.

[0176] As an optional implementation manner, the terminal processes at least one of the following based on the second collaboration layer:

[0177] receiving content forwarded by a peer layer of the second communication module;

[0178] Sending the content matched by the peer layer to the peer layer of the second communication module;

[0179] Splitting and packaging the content received by the second collaborative layer to obtain first content and second content, and sending the first content to a layer below the second collaborative layer of the first communication module, and sending the second content to a peer layer of the second communication module, wherein the second content matches the layer below the peer layer of the second communication module;

[0180] Splitting and packaging the portion of content received by the second collaborative layer to obtain third content, and sending the third content to a layer below the second collaborative layer of the first communication module, and sending another portion of the content received by the second collaborative layer to a peer layer of the second communication module;

[0181] Merging the content forwarded by the peer layer of the second communication module and the content delivered by the next layer of the second collaboration layer of the first communication module;

[0182] performing data processing on the content delivered by the peer layer of the second communication module according to the content delivered by the next layer of the second collaboration layer of the first communication module;

[0183] performing data processing on content delivered by a next layer of the second collaborative layer of the first communication module according to content delivered by a peer layer of the second communication module;

[0184] performing a device control operation based on at least one of content delivered by a peer layer of the second communication module and content delivered by a next layer of the second collaborative layer of the first communication module;

[0185] The second collaboration layer is a protocol layer in the protocol layers of the first communication module, and the peer layer of the second communication module and the second collaboration layer are the same protocol layer.

[0186] Among them, the above content, data processing and device control operations refer to the corresponding description of the above implementation method and are not repeated here.

[0187] The terminal processing the at least one item based on the second collaborative layer may include: during a communication transmission process of the second communication module based on the target protocol layer or during a communication transmission process based on the first communication module, the terminal processing the at least one item based on the second collaborative layer. That is, the terminal performing at least one operation in at least one of step 401 and step 402 based on the second collaborative layer.

[0188] In some embodiments, the above-mentioned terminal may also perform processing based on the second collaborative layer outside of steps 401 and 402, such as performing device control operations based on at least one of the content submitted by the peer layer of the second communication module and the content submitted by the next layer of the second collaborative layer of the first communication module.

[0189] The above-mentioned second collaborative layer can be the lowest layer among the protocol layers of the first communication module used in the data transmission process of the second communication module. In some embodiments, the above-mentioned second collaborative layer can be other protocol layers except the lowest layer among the protocol layers of the first communication module used in the data transmission process of the second communication module.

[0190] The peer layer of the above-mentioned second communication module and the second collaborative layer are the same protocol layer, which can be understood as the second collaborative layer and the peer layer are protocol layers of the same level, such as the second collaborative layer and the peer layer are both MAC layers, or the second collaborative layer and the peer layer are both application layers, the second collaborative layer and the peer layer are both RRC layers, etc.

[0191] In addition to the functions required by the second collaboration layer itself, it is also required to have at least one of the following functions:

[0192] Forwards SDUs, PDUs or raw data, headers, and signaling to the peer layer (also called peer entity);

[0193] Receive SDUs, PDUs or original data, headers, and signaling forwarded by the peer layer;

[0194] Receive the upper-layer PDU, split it, and package it into two SDUs of the lower-layer entity. The lower-layer SDU may carry at least part of the data information of the upper-layer PDU, or it may only carry control information.

[0195] Receive upper-layer PDUs, segment and package them into an SDU for delivery to lower-layer entities, and deliver SDUs, PDUs, or raw data, headers, signaling, etc. to peer entities;

[0196] Perform specified operations on information forwarded from peer entities, such as splitting, merging, discarding, encryption, and decryption, based on the SDU or PDU Header submitted by the lower-layer entity;

[0197] Based on the information forwarded by the peer entity, perform specified operations on the SDU and PDU Header submitted by the lower-layer entity, such as segmentation, merging, discarding, encryption and decryption;

[0198] Perform specified operations based on the SDU or PDU Header submitted by the lower-layer entity, or the SDU, PDU, raw data, header, or signaling forwarded by the peer entity, such as switching the RF front end, waking up a module, switching the device state, and sending or receiving specified signals.

[0199] In the above implementation, the second collaboration layer is used to realize the integration and collaboration of the first communication module and the second communication module, so as to reduce the complexity of the second communication module.

[0200] The protocol architecture in the above implementation may be referred to as a peer-to-peer mapping architecture.

[0201] The above implementation is similar to the above implementation. The functions of each layer of the two communication modules are equivalent. For example, the traditional protocol stack design can be followed, with six functional layers: PHY layer, MAC layer, PDCP layer, SDAP layer and RRC / application layer, which are responsible for the first, second, third, fourth, fifth and sixth functions respectively. The difference is that a certain layer entity of one communication module collaborates and data is integrated with the peer layer entity of the other module. Below the collaborative layer, the functional layers of the two modules work independently, while data integration and information exchange occur on the two collaborative peer layer entities. For example: as shown in Figures 8 to 10, the second collaborative layer is the MAC layer, application layer, RRC layer and PDCP layer.

[0202] In the example shown in FIG8 , the physical layers of the first communication module and the second communication module are independent, and the MAC layer entity of the first communication module is responsible for merging or splitting the data streams. However, unlike the examples shown in FIG5 to FIG7 , the MAC layer entity, on the one hand, delivers a MAC PDU to the physical layer of the module or receives a MAC SDU delivered from the physical layer of the module, and on the other hand, delivers another MAC PDU to the MAC entity of another module or receives a MAC SDU delivered by the MAC entity. The MAC entity responsible for delivering data to a higher-level entity or receiving data from a higher-level entity may need to merge multiple MAC PDUs into one MAC SDU before delivering it upward; or may need to divide one MAC SDU into multiple MAC PDUs before delivering them downward. Additional operations may be performed during the merging and splitting process.

[0203] In the example shown in Figure 9, the layer entities below the SDAP layer of the first and second communication modules are independent. The RRC / application layer of the first and second communication modules collaborate, with the entities of the first communication module responsible for merging or splitting data streams. In fact, this can also be implemented by entities in any layer between the MAC layer and the RRC / application layer, such as the PDCP layer in Figure 10.

[0204] As an optional implementation manner, the terminal performs communication transmission based on the target protocol layer and the protocol layer of the second communication module, including:

[0205] The terminal performs communication transmission based on the protocol layer, the adaptation layer, and the protocol layer of the second communication module, wherein the terminal processes at least one of the following based on the adaptation layer:

[0206] receiving content delivered by the protocol layer of the first communication module;

[0207] Translating the content delivered by the protocol layer of the first communication module into content matching the protocol layer of the second communication module, and delivering the translated content to the protocol layer of the second communication module;

[0208] receiving content delivered by the protocol layer of the second communication module;

[0209] translating the content delivered by the protocol layer of the second communication module into content matching the protocol layer of the first communication module, and delivering the translated content to the protocol layer of the second communication module;

[0210] performing data processing on the content submitted by the protocol layer of the second communication module according to the content submitted by the protocol layer of the first communication module;

[0211] performing data processing on the content submitted by the protocol layer of the first communication module based on the content submitted by the protocol layer of the second communication module;

[0212] A device control operation is performed according to at least one of the content delivered by the protocol layer of the first communication module and the content delivered by the protocol layer of the second communication module.

[0213] Among them, the above content, data processing and device control operations refer to the corresponding description of the above implementation method and are not repeated here.

[0214] The terminal processing the at least one item based on the adaptation layer may include: in a communication transmission process based on the protocol layer of the first communication module, the adaptation layer and the protocol layer of the second communication module, the terminal processing the at least one item based on the adaptation layer.

[0215] In some embodiments, the processing performed by the above-mentioned terminal based on the second collaborative layer can also be processing outside the communication transmission process based on the protocol layer, adaptation layer and protocol layer of the first communication module, such as performing device control operations based on at least one of the content submitted by the protocol layer of the first communication module and the content submitted by the protocol layer of the second communication module.

[0216] The adaptation layer is used to adapt the protocol layer of the first functional module and the protocol layer of the second communication module, such as translating data or signaling between the two communication modules. The adaptation layer can belong to the first communication module or the second communication module, or it can be a protocol layer outside of the first communication module or the second communication module.

[0217] In addition, the adaptation layer entity can be a peer layer of the functional layer responsible for collaboration, or a lower layer of the functional layer entity responsible for collaboration. The other functional layer entity connected to it is called the adapted layer.

[0218] In this embodiment, the adaptation layer is used for at least one of the following:

[0219] Receive SDUs, PDUs or original data, headers, and signaling forwarded by upper-layer or peer-layer entities;

[0220] Receive SDU, PDU or original data, header, and signaling delivered by the adaptation layer entity;

[0221] Translate the SDU, PDU or original data, header, and signaling from the upper or peer layer entity into the SDU, PDU or original data, header, and signaling of the adapted layer entity;

[0222] Translate the SDU, PDU or original data, header, and signaling delivered by the adaptation layer entity into the SDU, PDU or original data, header, and signaling of the peer layer entity.

[0223] In some embodiments, the adaptation layer may also be used to implement the functions of the first collaboration layer or the second collaboration layer.

[0224] In this embodiment, the protocol layer of the above-mentioned second communication module can have one or more functions, such as the second protocol layer (such as the PHY layer) is responsible for the above-mentioned first function and second function, and the third protocol layer (such as the MAC layer) is responsible for the above-mentioned third to sixth functions.

[0225] In this embodiment, the adaptation layer can support the situation where the protocol stack functional division of the second communication module is completely different from that of the first communication module, such as the PHY layer is responsible for the first and second functions, and the MAC layer is responsible for the third to sixth functions, thereby helping to improve the flexibility of the protocol.

[0226] For example: As shown in Figure 11, the various protocol layers of the first communication module are the same as the previous implementation method. The difference is that the PHY layer of the second communication module also has part of the functions of the first function and the second function. In this way, through an adaptation layer, the information delivered to or from the second communication module (including but not limited to PDU, SDU, Header, signaling, data, etc.) is translated into information that can be read or sent by the RLC layer of the first communication module. Similarly, the adaptation layer can also be coordinated at the RRC / application layer. As shown in Figure 12, at this time, the MAC layer of the second communication module may have at least part of the functions of the second to sixth functions. In fact, it can also be implemented in other functional layers, such as the PDCP layer in Figure 13.

[0227] As an optional implementation manner, the terminal processes at least one of the following based on the third collaboration layer:

[0228] receiving content delivered by an upper layer of the third collaborative layer of the first communication module;

[0229] Splitting and packaging a portion of the content submitted by the upper layer of the third collaborative layer of the first communication module, and sending the packaged content to the next layer of the third collaborative layer of the first communication module; and translating another portion of the content submitted by the upper layer of the third collaborative layer of the first communication module into content that matches the protocol layer of the second communication module, and delivering the translated content to the protocol layer of the second communication module;

[0230] receiving content delivered by the protocol layer of the second communication module;

[0231] Translating the content submitted by the protocol layer of the second communication module into content matched by the third collaboration layer of the first communication module, and merging the translated content with the content submitted by the next layer of the third collaboration layer of the first communication module;

[0232] performing data processing on the content submitted by the protocol layer of the second communication module according to the content submitted by the upper layer of the third collaboration layer of the first communication module;

[0233] performing data processing on the content submitted by the third collaboration layer of the first communication module according to the content submitted by the protocol layer of the second communication module;

[0234] Perform a device control operation according to at least one of the content submitted by the upper layer of the third collaboration layer of the first communication module and the content submitted by the protocol layer of the second communication module;

[0235] The third collaboration layer is a protocol layer in the protocol layers of the first communication module.

[0236] Among them, the above content, data processing and device control operations refer to the corresponding description of the above implementation method and are not repeated here.

[0237] The terminal processing the at least one item based on the third collaborative layer may include: during a communication transmission process of the second communication module based on the target protocol layer or during a communication transmission process based on the first communication module, the terminal processing the at least one item based on the third collaborative layer. That is, the terminal performing at least one operation in at least one of step 401 and step 402 based on the third collaborative layer.

[0238] In some embodiments, the processing performed by the above-mentioned terminal based on the third collaborative layer may also be processing outside of steps 401 and 402, such as performing device control operations based on at least one of the content submitted by the upper layer of the third collaborative layer of the first communication module and the content submitted by the protocol layer of the second communication module.

[0239] The above-mentioned third collaborative layer can be the lowest layer among the protocol layers of the first communication module used in the data transmission process of the second communication module. In some embodiments, the above-mentioned third collaborative layer can be other protocol layers except the lowest layer among the protocol layers of the first communication module used in the data transmission process of the second communication module.

[0240] The third collaboration layer has the functions of the collaboration and adaptation layer. For example, the third collaboration layer is used to implement the functions of the adaptation layer, and is also used to implement the functions of the first collaboration layer or the second collaboration layer.

[0241] In this embodiment, the third collaborative layer can support the situation where the protocol stack functional division of the second communication module is completely different from that of the first communication module, which is more conducive to reducing the complexity of the second communication module and can also avoid the introduction of an additional adaptation layer, thereby reducing the collaborative overhead.

[0242] For example, as shown in FIG14 , the RLC layer responsible for coordination in the first communication module has the function of an adaptation layer (wherein the adaptation layer is optional) and can be connected to unequal lower-layer functional entities.

[0243] It should be noted that, in the embodiments of the present application, Figures 5 to 14 are exemplified by illustrating that the first communication module is the main communication module and the second communication module is an extremely low power consumption communication module.

[0244] In this embodiment of the present application, a terminal performs communication transmission based on a first communication module; the terminal performs communication transmission based on a second communication module based on a target protocol layer, where the target protocol layer includes at least one of the following: a protocol layer of the second communication module; a protocol layer of the first communication module; and a first protocol layer, where the first protocol layer is a protocol layer outside of the first and second communication modules. This allows for parallel transmission via the two communication modules, thereby improving the transmission performance of the communication device.

[0245] Please refer to FIG15 , which is a structural diagram of a communication device provided in an embodiment of the present application. As shown in FIG15 , the communication device includes:

[0246] A first physical module 1501 of the first communication module and a second physical module 1502 of the second communication module;

[0247] The first physical module and the second physical module share at least one of an antenna, a baseband and a radio frequency front end; or the first physical module and the second physical module respectively include an independent antenna, a baseband and a radio frequency front end.

[0248] The first physical module 1501 of the first communication module includes an antenna, a baseband, and a radio frequency front end, and the second physical module 1502 of the second communication module includes an antenna, a baseband, and a radio frequency front end.

[0249] Sharing at least one of the antenna, baseband and RF front-end between the above-mentioned first physical module and the second physical module can be understood as at least one of the antenna, baseband and RF front-end between the first physical module and the second physical module is commonly used by these two physical modules.

[0250] In this embodiment, for a shared device, the device has corresponding functions of two modules. For example, for a shared baseband, the baseband has baseband functions of the first communication module and the second communication module.

[0251] The first physical module and the second physical module each include an independent antenna, baseband, and radio frequency front-end, and the two physical modules each include different antennas, basebands, and radio frequency front-ends. FIG15 illustrates an example in which the first physical module and the second physical module each include an independent antenna, baseband, and radio frequency front-end.

[0252] In this embodiment, two communication modules can be used to perform transmission through the first physical module and the second physical module, thereby improving the transmission performance of the communication device.

[0253] In this embodiment, the above-mentioned first communication module and second communication module can be the first communication module and second communication module in the embodiment shown in Figure 4. The relevant descriptions of the first communication module and the second communication module in the embodiment shown in Figure 4 can be applied to this embodiment and are not repeated here.

[0254] In some embodiments, an independent RF front end can provide independent signal transmission / reception channels for different communication modules to reduce mutual interference; an independent baseband can separate the signal processing of the two communication modules and completely shut down the baseband of the first communication module when the first communication module is not working, thereby minimizing power consumption.

[0255] In some implementations, when all hardware of two physical modules are not shared, this can minimize interference between the two modules and improve scheduling freedom.

[0256] In some embodiments, when all hardware of two physical modules is shared, it is equivalent to allowing the first communication module to simultaneously process two signals of the first communication module and the second communication module. When the second communication module is not enabled or has weak performance, the first communication module can take over the processing of the second communication module without switching to the first communication module on the network side, thereby reducing switching overhead.

[0257] As an optional implementation manner, sharing a radio frequency front end between the first physical module and the second physical module includes:

[0258] The first physical module and the second physical module share all or part of the components of the radio frequency front end.

[0259] For example, if the main components of the RF front end include an RF switch, an amplifier, a duplexer, and a filter, then at least one of the RF switch, amplifier, duplexer, and filter may be shared between the first physical module and the second physical module.

[0260] In this implementation, since the first physical module and the second physical module share all or part of the components of the radio frequency front end, the structural flexibility of the communication device can be improved.

[0261] As an optional implementation manner, when the first physical module and the second physical module share a radio frequency front end and an antenna:

[0262] The first baseband of the first physical module is connected to the first RF front end and the first antenna in sequence through a RF switch;

[0263] The second baseband of the second physical module is connected to the first RF front end and the first antenna in sequence through the RF switch.

[0264] In this embodiment, as shown in a of Figure 16 , the first baseband of the first physical module and the second baseband of the second physical module are both connected to the first RF front end and the first antenna in sequence via an RF switch. Figure 16 illustrates an example in which the first communication module is the primary communication module and the second communication module is the ultra-low power module. MR in Figure 16 represents the primary communication module.

[0265] In this implementation, the first physical module and the second physical module can share a radio frequency front end and an antenna, thereby saving hardware overhead of the terminal.

[0266] Optionally, the first RF front end includes: a duplexer, a transmit filter, a receive filter, a first RF switch, a second RF switch, a RF low noise amplifier (LNA), a RF power amplifier (PA), and a signal superposition circuit;

[0267] The first end of the first baseband is connected to the first end of the LNA, the second end of the first baseband is connected to the first end of the PA through the signal superposition circuit, the second end of the LNA is connected to one end of the receive filter through the first RF switch, and the other end of the receive filter is connected to the first antenna through the duplexer.

[0268] A first end of the second baseband is connected to a first end of the LNA, a second end of the second baseband is connected to a first end of the PA through the signal superposition circuit, a second end of the PA is connected to one end of the transmit filter through the second RF switch, and the other end of the transmit filter is connected to the first antenna through the duplexer.

[0269] This implementation can be shown in Figure 17. For the receive link, all components are shared between the two modules, and the received signal enters the baseband of the first and second communication modules simultaneously. For the transmit link, all components are also shared, and the signals generated by the baseband of the first and second communication modules are added and transmitted through the same transmit link. Because the two signals may have different frequency bands, the baseband of both modules must be able to handle signals in at least two frequency bands.

[0270] In this implementation, since the two modules share all components of the receiving link, the complexity of the terminal structure can be reduced.

[0271] Optionally, the first RF front end includes: a duplexer, a transmit filter, a first receive filter, a second receive filter, a first RF switch, a second RF switch, a third RF switch, a fourth RF switch, an LNA, and a PA;

[0272] The first end of the first baseband is connected to the first end of the first receive filter, the second end of the first receive filter is connected to the first end of the LNA via the first RF switch, the second end of the LNA is connected to the first antenna via the duplexer, the second end of the first baseband is connected to the first end of the PA via the second RF switch, the second end of the PA is connected to the first end of the transmit filter via the third RF switch, and the second end of the transmit filter is connected to the first antenna via the duplexer.

[0273] The first end of the second baseband is connected to the first end of the second receive filter, the second end of the second receive filter is connected to the first end of the LNA through the fourth RF switch, and the second end of the second baseband is connected to the first end of the PA through the second RF switch.

[0274] In this implementation, as shown in Figure 18, for the receive link, the LNA is shared and placed before the two RF switches, uniformly amplifying the signal. The signal then passes through two independent RF switches and filters, resulting in two signals that enter the baseband of the first and second communication modules, respectively. For the transmit link, all components are shared, and a single RF switch switches the signal to either the first or second communication module. This design minimizes the baseband overhead of the first and second communication modules, as they only need to process their own signals, minimizing mutual interference.

[0275] Optionally, the first RF front end includes: a duplexer, a first transmit filter, a second transmit filter, a receive filter, a first RF switch, a second RF switch, a third RF switch, an LNA, a first PA, a second PA, and a signal superposition circuit;

[0276] The first end of the first baseband is connected to the first end of the LNA, the second end of the LNA is connected to the first end of the receive filter through the first RF switch, and the second end of the receive filter is connected to the first antenna through the duplexer;

[0277] The second end of the first baseband is connected to the first end of the first PA, the second end of the first PA is connected to the first end of the first transmit filter via the second RF switch, and the second end of the first transmit filter is connected to the first antenna via the signal superposition circuit and the duplexer in sequence;

[0278] A first end of the second baseband is connected to a first end of the LNA, a second end of the second baseband is connected to a first end of the second PA, a second end of the second PA is connected to a first end of the second transmit filter through the third RF switch, and a second end of the second transmit filter is connected to the first antenna in sequence through the signal superposition circuit and the duplexer.

[0279] In this implementation, as shown in Figure 19, all components are shared for the receive link; the transmit link uses independent RF switches, PAs, and filters. Two signals are independently generated, added, and then transmitted through the antenna. In this implementation, the basebands of the first and second communication modules can receive two signals (e.g., signals with different frequency bands) while only needing to generate one signal of their own. This reduces the baseband processing power requirements and thus the baseband overhead.

[0280] As an optional implementation, when a baseband is shared between the first physical module and the second physical module: the baseband is respectively connected to a first end of a radio frequency front end of the first communication module and a first end of a radio frequency front end of the second communication module, a second end of the radio frequency front end of the first communication module is connected to a first antenna of the first communication module, and a second end of the radio frequency front end of the second communication module is connected to the first antenna of the second communication module;

[0281] In this implementation, as shown in c in FIG16 , the first communication module and the second communication module share the same baseband, which can save hardware overhead of the terminal.

[0282] As an optional embodiment, when the antenna is shared between the first physical module and the second physical module: the baseband of the first communication module is connected to the first end of the RF front end of the first communication module, and the second end of the RF front end of the first communication module is connected to the antenna; the baseband of the second communication module is connected to the first end of the RF front end of the second communication module, and the second end of the RF front end of the second communication module is connected to the antenna.

[0283] In this implementation, the first communication module and the second communication module share the same antenna, which can save hardware overhead of the terminal.

[0284] As an optional embodiment, when the RF front end is shared between the first physical module and the second physical module: the baseband of the first communication module is connected to the first end of the RF front end of the first communication module, and the second end of the RF front end is connected to the first antenna of the first communication module; the baseband of the second communication module is connected to the third end of the RF front end, and the fourth end of the RF front end is connected to the second antenna of the second communication module.

[0285] As an optional embodiment, when the antenna and baseband are shared between the first physical module and the second physical module: the first end of the baseband is connected to the first end of the RF front end of the first communication module, and the second end of the RF front end of the first communication module is connected to the antenna; the second end of the baseband is connected to the first end of the RF front end of the second communication module, and the second end of the RF front end of the second communication module is connected to the antenna.

[0286] In this implementation, the first communication module and the second communication module share an antenna and a baseband, which can save hardware overhead of the terminal.

[0287] As an optional embodiment, when the RF front end and baseband are shared between the first physical module and the second physical module: the first end of the baseband is connected to the first end of the RF front end, the second end of the RF front end is connected to the first antenna of the first communication module, and the third end of the RF front end is connected to the second antenna of the second communication module.

[0288] In this implementation, the first communication module and the second communication module share a radio frequency front end and a baseband, which can save hardware overhead of the terminal.

[0289] As an optional implementation, when the antenna, RF front end and baseband are shared between the first physical module and the second physical module: the baseband is connected to the first end of the RF front end, and the second end of the RF front end is connected to the antenna.

[0290] In this implementation, the first communication module and the second communication module share an antenna, a radio frequency front end, and a baseband, which can save hardware overhead of the terminal.
