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 embodiments 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.

[0039] 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 (Mobility Management Entity, MME), access mobility management function (Access and Mobility Management Function, AMF), session management function (Session Management Function, SMF), user plane function (User Plane Function, UPF), policy control function (Policy Control Function, PCF), policy and charging rules function unit (Policy and Charging Rules Function, PCRF), edge application service discovery function (Edge Application Server Discovery Function, EASDF), unified data management (Unified Data Management, UDM), unified data storage (Unified Data Repository, UDR), home user server (Home Subscriber Server, HSS), centralized network configuration (CNC), network storage function (Network Repository Function, NRF), network exposure function (Network Exposure Function, NEF), local NEF (Local NEF, or L-NEF), binding support function (Binding Support Function, BSF), application function (Application Function, AF), etc. 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.

[0040] In some embodiments, the terminal and the network side device can refer to Figure 2 As shown, the terminal includes a main communication module and an extremely low power consumption communication module, and the network side device includes a main communication module and an extremely low power consumption communication module. The main communication module and the extremely low power consumption communication module can communicate with each other, and the extremely low power consumption communication module of the terminal can communicate with the extremely low power consumption communication module of the network side device. It should be noted that Figure 2 This is just 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 ultra-low power consumption communication module of the terminal can communicate with the main communication module of the network side device.

[0041] 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.

[0042] In some embodiments, the extremely low power communication module can support extremely low power communication (such as supporting sending signals 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 sending signals 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 above-mentioned extremely low power communication module is a backscatter communication module, the main communication module will naturally excite the extremely low power communication module when sending signals, so the additional backscatter signal generated has almost no additional overhead.

[0043] In some embodiments, the extremely low power communication may include at least one of the following:

[0044] Supports backscatter communication for energy harvesting;

[0045] Support powered backscatter communications;

[0046] Low power reception.

[0047] For example: Ultra-low power communication modules can support energy harvesting, including but not limited to harvesting energy from light, solar energy, wireless signals, etc.

[0048] In addition, the excitation source signal of the backscatter communication may be generated by the terminal itself with the extremely low power consumption communication module or by other devices.

[0049] 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.

[0050] Backscatter communication is the most representative technology for ultra-low power communication. In principle, backscatter communication equipment controls the reflection coefficient of the circuit by adjusting its internal impedance, thereby changing the amplitude, frequency, phase, etc. of the RF signal from other devices or the environment to achieve signal modulation. Typical backscatter communication hardware modules can be as follows: Figure 3 As shown, it includes: antenna unit, energy collection module or energy supply module, microcontroller, signal receiving module, channel coding and modulation module, memory or sensor module, etc. Among them, the signal receiving module is responsible for receiving the downlink signal sent to the backscattering device by the network side device or card reader, etc. Its architecture and technology can reuse the low-power wake-up receiver technology defined in the protocol or newly defined in the future; since the backscattering communication does not actively generate radio frequency signals, its energy consumption is extremely low, usually between tens of microwatts and hundreds of microwatts, and the energy collection module can collect energy such as radio frequency signals, light energy, thermal energy, etc. in the environment to modulate, demodulate and reflect the signal, without having its own energy source such as batteries; it can also be supplied by small energy supply modules such as button batteries, thereby reducing the strength requirements of the energy supply signal. In addition to the above typical components, the backscattering communication technology can integrate low-power amplifier modules to improve the receiving sensitivity and backscattering signal power.

[0051] It should be noted that in the embodiments of the present application, backscatter communication is only an example of extremely low power consumption communication. In the embodiments of the present application, there is no limitation on extremely low power consumption communication. For example, it may be extremely low power consumption communication defined in the protocol, such as communication of a communication module with power consumption ranging from tens of microwatts to hundreds of microwatts.

[0052] In the following, in combination with the accompanying drawings, a communication method, device, and terminal provided in an embodiment of the present application are described in detail through some embodiments and their application scenarios.

[0053] See also Figure 4 , Figure 4 is a flow chart of a communication method provided in an embodiment of the present application, such as Figure 4 As shown, the following steps are included:

[0054] Step 401: The terminal performs communication transmission based on the first communication module;

[0055] 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:

[0056] a protocol layer of the second communication module;

[0057] a protocol layer of the first communication module;

[0058] The first protocol layer is a protocol layer outside the first communication module and the second communication module.

[0059] 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 is the main communication module, and the second communication module is the extremely low power communication module, or the second communication module is the main communication module, and the first communication module is the extremely low power communication module. The extremely low power communication module is a module that supports extremely low power communication, and the power consumption of the main communication module is higher than that of the extremely low power communication module.

[0060] In some embodiments, the first communication module and the second communication module are two different extremely low power consumption communication modules. For example, the first communication module and the second communication module are communication modules that can send signals in the form of backscattering and actively generate carrier waves. For example, the first device is an IoT terminal with two communication modes, such as an IoT terminal that can send signals in the form of backscattering and actively generate carrier waves.

[0061] 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 part or all of the module contents.

[0062] 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.

[0063] The above-mentioned terminal performs communication transmission of the second communication module based on the target protocol layer, which can be understood as the protocol layer used in the communication transmission process through the second communication module is the above-mentioned target protocol layer. Wherein, the communication transmission includes at least one of sending and receiving through the second communication module.

[0064] The first protocol layer is a protocol layer outside the first communication module and the second communication module, which means that the 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.

[0065] 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, and 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.

[0066] The above step 402 may include:

[0067] The terminal transmits communication of the second communication module based on the protocol layer of the first communication module and the protocol layer of the second communication module; or,

[0068] 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,

[0069] The terminal transmits communication based on the first protocol layer and the second communication module's protocol layer; or,

[0070] 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

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

[0072] The terminal transmits the communication of the second communication module based on the protocol layer of the second communication module.

[0073] 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.

[0074] 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.

[0075] In some implementations, 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.

[0076] It should be noted that step 401 and step 402 may be performed simultaneously or sequentially. Figure 4 An example is given in which step 401 is executed first and then step 402 is executed.

[0077] In the embodiment of the present application, the above steps can realize parallel transmission through two communication modules, thereby improving the transmission performance of the terminal, such as improving the reliability and rate of terminal transmission, and because the same protocol layer can be shared, the energy consumption of the terminal can also be reduced. In addition, since the above target protocol layer is used when the communication transmission is performed through the second communication module, it can be realized that the second communication module does not need to have all the protocol layers required for communication transmission, thereby reducing the complexity of the second communication module.

Wherein, when submitting the PDU / SDU, according to the quality of service (Quality of Service, QoS) ID, QoS requirements and other QoS-related information, the PDU / SDU is mapped to the corresponding wireless bearer, or the PDU / SDU with the same QoS ID or QoS requirement belongs to the same QoS flow (QoSFlow).

[0136] 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.

[0137] 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 function and the second function, and the MAC layer is responsible for the third to sixth functions.

[0138] 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.

[0139] As an optional implementation manner, the terminal processes at least one of the following based on the first collaborative layer:

[0140] 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;

[0141] Segmenting the content acquired by the first collaborative layer of the first communication module, and transmitting the segmented content to the lower layer of the first communication module and the lower layer of the second communication module respectively;

[0142] 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;

[0143] 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;

[0144] 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;

[0145] 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;

[0146] The lower layer is a next protocol layer of the first collaborative layer.

[0147] The terminal processing at least one of the above items based on the first collaborative layer may include: in the process of the terminal performing communication transmission of the second communication module based on the target protocol layer or in the process of performing communication transmission based on the first communication module, the terminal processes at least one of the above items based on the first collaborative layer. That is, the terminal performs at least one of the above operations based on the first collaborative layer in at least one of step 401 and step 402.

[0148] In some embodiments, the terminal may perform processing based on the first collaborative layer other than step 401 and step 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.

[0149] The first collaboration layer is a protocol layer that is used to provide services for the data of the second communication module in addition to processing the data of the first communication module itself. That is, the first collaboration layer needs to have at least one of the above functions in addition to the functions it needs to have.

[0150] In some embodiments, the above content includes at least one of the following:

[0151] SDU, PDU, raw data, packet header, signaling.

[0152] For example, the above-mentioned first collaborative layer is used to receive the upper-layer entity PDU, 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.

[0153] In some embodiments, the data processing includes at least one of the following:

[0154] Split, merge, discard, encrypt, and decrypt.

[0155] For example, the first coordination layer is used to perform specified operations such as splitting, merging, discarding, encrypting, decrypting, etc. on a PDU submitted by another lower-layer entity according to a PDU or PDU Header submitted by another lower-layer entity.

[0156] In some embodiments, the device control operation includes at least one of the following:

[0157] Switch the RF front end, wake up the communication module, switch the device status, send the specified signal, and receive the specified signal.

[0158] For example: the first collaborative layer is used to perform specified operations according to 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 state of the device, sending or receiving a specified signal, wherein the state of the switching device includes but is not limited to the RRC state and the connection management (CM) state.

[0159] In the above implementation manner, the above-mentioned first collaborative layer may be the lowest layer of the protocol layers of the first communication module used in the data transmission process of the second communication module. If the protocol layers of the first communication module used in the data transmission process of the second communication module are RRC layer, SDAP layer, PDCP layer, RLC layer and MAC layer, then the above-mentioned first collaborative layer is MAC; if the protocol layers of the first communication module used in the data transmission process of the second communication module are RRC layer, SDAP layer, PDCP layer and RLC layer, then the above-mentioned first collaborative layer is RLC layer; if the protocol layers of the first communication module used in the data transmission process of the second communication module are RRC layer, SDAP layer and PDCP layer, then the above-mentioned first collaborative layer is PDCP layer; if the protocol layers of the first communication module used in the data transmission process of the second communication module are RRC layer and SDAP layer, then the above-mentioned first collaborative layer is SDAP layer; if the protocol layer of the first communication module used in the data transmission process of the second communication module is RRC layer, then the above-mentioned first collaborative layer is RRC layer.

[0160] 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.

[0161] The first collaboration layer may be the highest layer among the protocol layers of the first communication module, and the first collaboration layer may also be other protocol layers except the highest layer among the protocol layers of the first communication module.

[0162] The high-level 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 of them.

[0163] 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 to reduce the complexity of the second communication module.

[0164] 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 certain protocol layer is unique in the terminal, the relevant description of the protocol layer may not reflect the entity.

[0165] 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 entities of the other module, and submits data to the module and the low-level entities of the other module. Below the collaboration layer, the functional layers of the two communication modules work independently, and the fusion of data and information exchange occur on the first collaboration layer, thereby reducing the complexity of the second communication module.

[0166] The protocol architecture in the above implementation may be referred to as a master-slave mapping architecture.

[0167] For ease of explanation, in the embodiments of the present application, the first communication module and the second communication module are described as having only one protocol stack. However, in some implementations, 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.

[0168] Taking the MAC layer of the first communication module as an example, Figure 5 As shown, 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 by the physical layers of the two modules.

[0169] Taking the above-mentioned first collaborative layer as the application layer or RRC layer of the first communication module as an example, Figure 6As shown, 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 the data stream.

[0170] The entity responsible for data flow segmentation or merging is the entity that performs actual operations on data, while the entity responsible for execution and the entity responsible for logic may not be the same. For example, the operation performed by the MAC layer is informed by a higher layer, such as determining the data segmentation or merging method at the PDCP layer, and the PDCP labels the data or informs the MAC layer of the segmentation or merging method or principle for execution. In the case where the execution entity and the logical entity are not the same entity, the logical entity may be the responsibility of a higher layer; or one of the two equivalent entities between different modules may be responsible.

[0171] The first coordination layer can also be implemented by an entity of any layer between the MAC layer or the RRC layer application layer, such as Figure 7 RLC layer.

[0172] In the above implementation mode, the terminal can have two communication modules for multiple uses. 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.

[0173] As an optional implementation manner, the terminal processes at least one of the following based on the second collaboration layer:

[0174] Receiving content forwarded by a peer layer of the second communication module;

[0175] Sending the content matched by the peer layer to the peer layer of the second communication module;

[0176] 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 next layer of 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 next layer of the peer layer of the second communication module;

[0177] Splitting and packaging part of the 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 part of the content received by the second collaborative layer to a peer layer of the second communication module;

[0178] 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;

[0179] 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;

[0180] According to the content delivered by the peer layer of the second communication module, data processing is performed on the content delivered by the next layer of the second collaboration layer of the first communication module;

[0181] Performing a device control operation according to 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;

[0182] The second collaboration layer is a protocol layer in the protocol layer of the first communication module, and the peer layer of the second communication module and the second collaboration layer are the same protocol layer.

[0183] Among them, the above content, data processing and device control operations refer to the corresponding description of the above implementation methods and are not repeated here.

[0184] The terminal processing the at least one of the above items based on the second collaborative layer may include: in the communication transmission process of the second communication module based on the target protocol layer or in the communication transmission process based on the first communication module, the terminal processes the at least one of the above items based on the second collaborative layer. That is, the terminal performs the at least one operation based on the second collaborative layer in at least one of step 401 and step 402.

[0185] In some embodiments, the above-mentioned terminal may also perform processing based on the second collaborative layer outside of step 401 and step 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.

[0186] The above-mentioned second collaborative layer may 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 may 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.

[0187] 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.

[0188] In addition to the functions required by itself, the second collaboration layer must also have at least one of the following functions:

[0189] Forwards SDUs, PDUs or raw data, headers, and signaling to the peer layer (also called peer entity);

[0190] Receive SDU, PDU or original data, header, and signaling forwarded by the peer layer;

[0191] Receive an upper layer PDU, split and package it into two SDUs of lower layer entities, where the lower layer SDU may carry at least part of the data information of the upper layer PDU, or may only carry control information;

[0192] Receive upper layer PDU, split and package it into 1 SDU for lower layer entity, and SDU, PDU, or raw data, header, signaling, etc. delivered to peer entity;

[0193] According to the SDU or PDU Header submitted by the lower-layer entity, perform specified operations on the information forwarded from the peer entity, such as segmentation, merging, discarding, encryption and decryption, etc.

[0194] According to 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, etc.

[0195] Perform specified operations based on the SDU or PDU Header submitted by the lower-layer entity, or the SDU, PDU, original data, header or signaling forwarded by the peer entity, such as switching the RF front end, waking up a module, switching the status of the device, sending or receiving a specified signal.

[0196] In the above implementation, the integration and coordination of the first communication module and the second communication module are achieved through the second coordination layer, so as to reduce the complexity of the second communication module.

[0197] The protocol architecture in the above implementation may be referred to as a peer-to-peer mapping architecture.

[0198] 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 including 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 another 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: Figures 8 to 10As shown, the second coordinated layers are the MAC layer, application layer, RRC layer and PDCP layer.

[0199] Among them, Figure 8 In the example shown, 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, but is not related to the Figures 5 to 7 The difference from the example shown is that 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. Among them, 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 it 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.

[0200] exist Fig. 9 In the example shown, the layer entities below the SDAP layer of the first communication module and the second communication module are independent, the RRC / application layer of the first communication module and the RRC / application layer of the second communication module cooperate, and the entity of the first communication module is responsible for merging or splitting the data stream. In fact, it can also be implemented by the entity of any layer between the MAC layer and the RRC / application layer, such as Fig.10 PDCP layer.

[0201] 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:

[0202] The terminal performs communication transmission based on the protocol layer, the adaptation layer of the first communication module, and the protocol layer of the second communication module, wherein the terminal processes at least one of the following based on the adaptation layer:

[0203] receiving content delivered by the protocol layer of the first communication module;

[0204] Translating the content submitted by the protocol layer of the first communication module into content matched by the protocol layer of the second communication module, and delivering the translated content to the protocol layer of the second communication module;

[0205] receiving content submitted by the protocol layer of the second communication module;

[0206] Translating the content submitted by the protocol layer of the second communication module into content matched by the protocol layer of the first communication module, and delivering the translated content to the protocol layer of the second communication module;

[0207] 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;

[0208] According to the content submitted by the protocol layer of the second communication module, data processing is performed on the content submitted by the protocol layer of the partial content of the first communication module;

[0209] 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.

[0210] Among them, the above content, data processing and device control operations refer to the corresponding description of the above implementation methods and are not repeated here.

[0211] The terminal processing at least one of the above items based on the adaptation layer may include: in the process of communication transmission 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 at least one of the above items based on the adaptation layer.

[0212] In some embodiments, the processing performed by the above-mentioned terminal based on the second collaborative layer may 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.

[0213] 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 may belong to the first communication module or the second communication module, or may be a protocol layer outside the first communication module or the second communication module.

[0214] In addition, the adaptation layer entity may be a peer layer of the functional layer responsible for coordination, or a lower layer of the functional layer entity responsible for coordination, and the other functional layer entity connected thereto is called an adapted layer.

[0215] In this embodiment, the above-mentioned adaptation layer is used for at least one of the following:

[0216] Receive SDU, PDU or original data, header, signaling forwarded by upper layer or peer layer entity;

[0217] Receive SDU, PDU or original data, header, signaling delivered by the adaptation layer entity;

[0218] Translate the SDU, PDU or original data, header, signaling from the upper layer or peer layer entity into the SDU, PDU or original data, header, signaling of the adapted layer entity;

[0219] 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.

[0220] In some implementations, the adaptation layer may also be used to implement the functions of the first coordination layer or the second coordination layer.

[0221] In this embodiment, the protocol layer of the above-mentioned second communication module may have one or more functions, such as the second protocol layer (such as PHY layer) is responsible for the above-mentioned first function and second function, and the third protocol layer (such as MAC layer) is responsible for the above-mentioned third to sixth functions.

[0222] In this implementation, the adaptation layer can support the situation where the functional division of the protocol stack 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.

[0223] For example: Fig.11 As shown, the various protocol layers of the first communication module are the same as the previous implementation, except that the PHY layer of the second communication module has both the first function and part of the second function, so that 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 RRC / application layer can also be coordinated with the adaptation layer for collaboration, such as Fig.12 As shown, 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 Fig.13 PDCP layer.

[0224] As an optional implementation manner, the terminal processes at least one of the following based on the third collaboration layer:

[0225] receiving content delivered by an upper layer of the third collaboration layer of the first communication module;

[0226] Splitting and packaging part 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 part of the content submitted by the upper layer of the third collaborative 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;

[0227] receiving content submitted by the protocol layer of the second communication module;

[0228] Translating the content submitted by the protocol layer of the second communication module into content matched by the third coordination layer of the first communication module, and merging the translated content with the content submitted by the next layer of the third coordination layer of the first communication module;

[0229] 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;

[0230] performing data processing on the content submitted by the third coordination layer of the first communication module according to the content submitted by the protocol layer of the second communication module;

[0231] Execute 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;

[0232] The third collaboration layer is a protocol layer in the protocol layers of the first communication module.

[0233] Among them, the above content, data processing and device control operations refer to the corresponding description of the above implementation methods and are not repeated here.

[0234] The terminal processing the at least one of the above items based on the third collaborative layer may include: in the communication transmission process of the second communication module based on the target protocol layer or in the communication transmission process based on the first communication module, the terminal processes the at least one of the above items based on the third collaborative layer. That is, the terminal performs the at least one operation based on the third collaborative layer in at least one of step 401 and step 402.

[0235] In some embodiments, the processing performed by the above-mentioned terminal based on the third collaborative layer may also be processing outside of step 401 and step 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.

[0236] The third collaborative layer may 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 third collaborative layer may 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.

[0237] 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.

[0238] In this implementation, the third collaboration 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 collaboration overhead.

[0239] For example: Fig.14 As shown, 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.

[0240] It should be noted that in the embodiments of this application Figures 5 to 14 The following example is taken as follows: the first communication module is a main communication module, and the second communication module is an extremely low power consumption communication module.

[0241] In the embodiment of the present application, the terminal performs communication transmission based on the first communication module; the terminal performs communication transmission of the second communication module based on the target protocol layer, and the target protocol layer includes at least one of the following: the protocol layer of the second communication module; the protocol layer of the first communication module; the first protocol layer, and the first protocol layer is a protocol layer outside the first communication module and the second communication module. In this way, parallel transmission can be achieved through two communication modules, thereby improving the transmission performance of the communication device.

[0242] See also Fig.15 , Fig.15 is a structural diagram of a communication device provided in an embodiment of the present application, such as Fig.15 As shown, including:

[0243] A first physical module 1501 of the first communication module and a second physical module 1502 of the second communication module;

[0244] 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.

[0245] 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.

[0246] 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.

[0247] 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.

[0248] The first physical module and the second physical module respectively include independent antennas, basebands and radio frequency front ends, and the two physical modules respectively include different antennas, basebands and radio frequency front ends. Fig.15 An example is given in which the first physical module and the second physical module respectively include independent antennas, basebands, and radio frequency front ends.

[0249] 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.

[0250] In this embodiment, the first communication module and the second communication module may be Figure 4 The first communication module and the second communication module in the embodiment shown, Figure 4 The related descriptions of the first communication module and the second communication module in the illustrated embodiment can be applied to this embodiment and will not be described in detail here.

[0251] 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 can completely shut down the baseband of the first communication module when the first communication module is not working, thereby minimizing power consumption.

[0252] In some implementations, when all hardware of two physical modules are not shared, this can minimize the interference between the two modules and improve the degree of freedom of scheduling.

[0253] In some embodiments, when all hardware of two physical modules are 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.

[0254] As an optional implementation manner, the sharing of a radio frequency front end between the first physical module and the second physical module includes:

[0255] The first physical module and the second physical module share all or part of the components of the radio frequency front end.

[0256] For example: the main components of the RF front end include an RF switch (Switch), an amplifier, a duplexer and a filter (Filter), then at least one of the RF switch (Switch), amplifier, duplexer and filter (Filter) is shared between the first physical module and the second physical module.

[0257] 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.

[0258] As an optional implementation manner, when a radio frequency front end and an antenna are shared between the first physical module and the second physical module:

[0259] 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;

[0260] 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.

[0261] In this embodiment, the Fig.16 As shown in a, the first baseband of the first physical module and the second baseband of the second physical module are connected to the first RF front end and the first antenna in sequence through the RF switch. Fig.16 Take the first communication module as the main communication module and the second communication module as the extremely low power consumption module as an example. Fig.16 MR stands for main communication module

[0262] 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.

[0263] 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 (Low Noise Amplifier, LNA), a RF power amplifier (power amplifier, PA) and a signal superposition circuit;

[0264] 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 receiving filter through the first RF switch, and the other end of the receiving filter is connected to the first antenna through the duplexer;

[0265] The first end of the second baseband is connected to the first end of the LNA, the second end of the second baseband is connected to the first end of the PA through the signal superposition circuit, the 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.

[0266] This embodiment can be Fig.17 As shown, for the receiving link, all components of the two modules are shared, and the received signal enters the baseband of the first communication module and the second communication module at the same time; for the transmitting link, all components are also shared, and the signals generated by the baseband of the first communication module and the second communication module are added and sent out through the same transmitting link. Since the two signals may have different frequency bands, the baseband of the two modules must at least be able to handle signals in two frequency bands.

[0267] In this implementation, since the two modules share all components of the receiving link, the complexity of the terminal structure can be reduced.

[0268] 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;

[0269] Wherein, the first end of the first baseband is connected to the first end of the first receiving filter, the second end of the first receiving filter is connected to the first end of the LNA through the first RF switch, the second end of the LNA is connected to the first antenna through the duplexer, the second end of the first baseband is connected to the first end of the PA through the second RF switch, the second end of the PA is connected to the first end of the transmitting filter through the third RF switch, and the second end of the transmitting filter is connected to the first antenna through the duplexer;

[0270] 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.

[0271] This implementation method, such as Fig.18As shown, for the receiving link, the LNA is shared and placed before the two RF switches to uniformly amplify the signal, and then pass through two independent RF switches and filters to obtain two signals, which enter the baseband of the first communication module and the second communication module respectively; for the transmitting link, all components are shared and switched to the first communication module or the second communication module through an RF switch. Such a design can minimize the overhead of the baseband of the first communication module and the second communication module, because they only need to process their own signals and have less mutual interference.

[0272] 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;

[0273] 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 receiving filter through the first RF switch, and the second end of the receiving filter is connected to the first antenna through the duplexer;

[0274] 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 through the second RF switch, and the second end of the first transmit filter is connected to the first antenna through the signal superposition circuit and the duplexer in sequence;

[0275] The first end of the second baseband is connected to the first end of the LNA, the second end of the second baseband is connected to the first end of the second PA, the second end of the second PA is connected to the first end of the second transmit filter through the third RF switch, and the second end of the second transmit filter is connected to the first antenna through the signal superposition circuit and the duplexer in sequence.

[0276] In this embodiment, if Fig.19 As shown, for the receiving link, all components are shared; the transmitting link uses independent RF switches, PAs and filters, and the two signals are independently generated, added and then sent out through the antenna. In this implementation, the baseband of the first communication module and the second communication module can receive two signals (for example, two signals with different frequency bands), and only needs to generate one signal of its own, which has a lower requirement on the baseband processing capability and reduces the baseband overhead.

[0277] As an optional implementation, in the case where the 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 a first antenna of the second communication module;

[0278] In this embodiment, if Fig.16 As shown in c, the first communication module and the second communication module share the same baseband, which can save the hardware overhead of the terminal.

[0282] As an optional implementation, 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.

[0283] 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.

[0284] As an optional implementation, 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.
