[0061] In response to the description in the background art section, this application proposes to implement HPUE (High Power User Equipment) using the dual transmission frequency bands of ENDC (E-UTRAN New Radio–Dual Connectivity) technology. In this way, the terminal device can simultaneously transmit the data to be transmitted (i.e., uplink data) on multiple different frequency bands. Thus, the secondary network node on the network side can receive the uplink data of the corresponding frequency and then forward it to the primary network node. The primary network node combines the received uplink data of the corresponding frequency with the uplink data forwarded by the secondary network node to improve the signal quality of the uplink data and reliably and accurately obtain the target transmission data transmitted by the terminal device, without adding any hardware cost to the terminal device, and reducing the linearity index requirements for the PA (Power Amplifier) of the terminal device and the index requirements for the TX SAW (surface acoustic wave) output by the PA.

[0062] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the protection scope of this application.

[0063] Refer to Figure 1, is a schematic structural diagram of an optional example of the communication processing system proposed in this application. The system may include but is not limited to: at least one terminal device 110, a main network node 120, at least one secondary network node 130, and a control node 140, where:

[0064] The terminal device 110 may include but is not limited to: smartphones, tablets, wearable devices, laptops, smart watches, Augmented Reality (AR) devices, Virtual Reality (VR) devices, in-vehicle devices, robots, intelligent medical devices, intelligent transportation devices, desktop computers, etc., which can be determined according to the communication processing application scenario. This application does not limit the device type and quantity of the terminal device 110 included in the communication processing system.

[0065] In the application of a communication network architecture such as the ENDC technology and the 3GPP (3rd Generation Partnership Project) network structure, the E-UTRAN radio access network usually consists of multiple eNodeBs (Evolved NodeBs, denoted as network nodes). Each network node can independently manage the terminal devices within the coverage of its respective cell and the radio resources of the cell. This application does not elaborate on the implementation methods for managing the terminal devices and radio resources of each network node.

[0066] Among the multiple network nodes in the communication processing system, the network node connected to the control node 130 can be determined as the main network node 120. For example, Figure 2 in the 3GPP LTE Dual-Connectivity (DC) network structure shown, the MeNB that provides the S1-MME (Mobility Management Entity) connection; the network node connected to the main network node and providing additional resources is determined as the secondary network node 130, such as Figure 2 the SeNB shown. Between the main network node 120 and the secondary network node 130, data and signaling can be transmitted through the X2 interface. Each network node involved in the embodiments of this application may include but is not limited to network devices such as base stations. This application does not elaborate on the device configuration parameters of each network node.

[0067] The control node 140 can be used to process application data and signaling in the communication processing system, and implement communication control and management of network nodes and terminal devices, such as access control, mobility management, attachment and detachment of terminal devices, session management, selection of SGW (Serving GateWay) and PGW (Packet Data Network GateWay) to implement user data packet forwarding, etc. In the embodiments of this application, after obtaining the inter-frequency transmission request message sent by the terminal device, the control node can determine whether the terminal device supports the inter-frequency transmission mode, whether the main network node supports the uplink inter-frequency reception function, etc. This application does not elaborate on the processing content implemented by the control node 140 in the communication processing method proposed in this application, and it can be determined according to the situation.

[0068] Combined with the Figure 2 network structure shown above, the control node 140 may include an MME node, that is, a key control node of the 3GPP protocol LTE access network. Data transmission between the main network node 120 and the control node 140 can be realized through the control plane link of S1-MME to achieve data transmission between the access network and the core network. This application does not limit the node types and their quantities included in the control node 140 in the communication processing system. In other types of network structures, the control node 140 may be other devices in the core network that provide network signaling management and control. This application does not give detailed examples one by one here.

[0069] In the actual application of this application, the above terminal device 110 can access the main network node 120 and at least one secondary network node 130 to form at least two uplink communication links. In this way, when the terminal device moves to the cell edge position and is in a weak field communication environment, in order to ensure the quality of uplink data communication, radio frequency signals carrying the same data to be transmitted can be simultaneously transmitted at different frequencies through the at least two uplink communication links. The implementation process can refer to the description of the corresponding part of the method embodiment below.

[0070] Based on the above analysis, in the Figure 3 LTE dual-connection network structure in 3GPP, the data plane radio bearer can be served by MeNB (MCG (Master Cell Group) bearer) or SeNB independently (SCG (Secondary Cell Group) bearer), or served by MeNB and SeNB simultaneously (Split Bearer). The required bearer mode can be flexibly selected according to actual communication requirements. For example, in order to increase the downlink rate of the terminal device, the user capacity of the cell, and seamless handover between different cells (data does not drop the connection), the split bearer mode can be selected to implement the transmission of downlink data.

[0071] As Figure 3 shown, after the downlink data sent by the control node of the core network is sent to the main network node, combined with the functions of each layer such as PDCP (Packet Data Convergence Protocol), RLC (Radio Link Control), and MAC (Medium Access Control) included in the air interface protocol stack, the air interface data (i.e., downlink data) can be split into two bearers at the PDCP layer of the main network node MeNB. One path of downlink data continues to be sent to the RLC layer of the main network node and is sent to the terminal device UE through the MAC layer. The other path of downlink data can be sent to the RLC layer of the secondary network node SeNB through the X2 interface and is sent to the terminal device UE through the MAC layer of SeNB. Then, the terminal device UE combines the downlink data sent from different eNBs, which helps to improve user performance, increase the overall throughput of users, and reduce the handover delay.

[0072] Based on the ENDC function supported by the terminal device described above, that is, supporting the simultaneous transmission power of two different frequency bands, in order to improve the transmission signal quality of the terminal device, improve the transmission reliability of its uplink data, and reduce the requirements for the linear index of the PA and the index requirements of the TX SAW, compared with the data upload method in which the main network node sends the uplink data transmitted by the terminal device to the control node, this application proposes that the terminal device enters the inter-frequency transmission mode, so that the terminal device accesses the main network node and at least one secondary network node respectively. In this way, after the terminal device simultaneously transmits the uplink data on multiple different frequency bands (such as Figure 3 taking two frequency bands as an example for illustration) (different from the above-mentioned split bearer mode), both the main network node and the secondary network node can detect the uplink data corresponding to the frequency. The secondary network node then sends the detected uplink data to the main network node, and the PDCP layer of the main network node combines and processes the two paths of uplink data with different frequencies to accurately obtain the content of the uplink data sent by the terminal device.

[0073] It should be understood that Figure 1 the structure of the communication processing system shown does not constitute a limitation on the communication processing system in the embodiments of this application. In practical applications, the system may include more Figure 1 nodes / devices than those shown, and this application does not list them one by one here.

[0074] Referring to Figure 4 , it is a schematic flowchart of an optional example of the communication processing method proposed by this application. This method can be applied to the communication processing system described above, and the terminal device in the system can execute the communication processing method described in this embodiment, such as Figure 4As shown, the method may include:

[0075] Step S41, determining that the terminal device enters the inter-frequency transmission mode; in the inter-frequency transmission mode, the terminal device accesses the main network node and at least one secondary network node respectively;

[0076] In the embodiments of the present application, when the terminal device supports the inter-frequency HPUE function, in order to improve the quality of the radio frequency signal transmitted by the terminal device, for example, when the terminal device is in a weak-field communication environment, the terminal device can be controlled to enter the inter-frequency transmission mode, that is, a transmission mode that supports the simultaneous transmission function of multiple radio frequency signals with different frequencies carrying the same data to be transmitted. To realize the transmission of multiple radio frequency signals with different frequencies to the network side, on the basis of accessing the main network node, the terminal device will also access at least one secondary network node to form multiple uplink communication links. The present application does not limit the implementation method of constructing these multiple uplink communication links and the control method of the inter-frequency transmission mode of the terminal device, etc.

[0077] Step S42, obtaining multiple radio frequency signals with different frequencies carrying the same data to be transmitted;

[0078] Combined with the above description of the technical solution of the present application, after the terminal device enters the inter-frequency transmission mode and determines the data to be transmitted, a power amplifier (PA) with different configuration parameters can be used to process the same data to be transmitted after modulation to obtain multiple radio frequency signals with different frequencies. The present application does not elaborate on the implementation method of the terminal device obtaining any radio frequency signal with a frequency carrying the data to be transmitted.

[0079] Among them, for multiple different frequencies of the data to be transmitted, it can be determined in advance through negotiation between the terminal device and each network node, such as determining according to information such as the relative positions between the terminal device and the main network node and the secondary network node, and their respective network configuration parameters / performance. The present application does not elaborate on the implementation process.

[0080] Step S43, sending the multiple radio frequency signals with different frequencies to the main network node and the secondary network node configured with the corresponding frequencies, so that the secondary network node transmits the received radio frequency signal to the main network node, and the main network node performs merging processing on the received multiple radio frequency signals with different frequencies to obtain the target transmission data.

[0081] After the terminal device obtains multiple RF signals of different frequencies carrying the same data to be transmitted according to the above method, it can simultaneously transmit these multiple RF signals at these multiple different frequencies through at least one transmitter (such as an antenna). In this case, the terminal device has accessed the main network node and at least one secondary network node. Different network nodes can support one frequency band. Thus, the RF receivers (such as antennas) of the main network node and the secondary network node can receive the RF signals corresponding to the frequencies of the supported frequency bands. For example, the main network node can receive the RF signal of the first frequency, and the secondary network node can receive the RF signal of the second frequency. The data to be transmitted carried by these two RF signals is the same, but affected by the communication environment where the terminal device is located, it may affect the quality of the RF signals received by each network node, resulting in the possibility that each network node may not be able to obtain the complete and accurate content of the data to be transmitted.

[0082] To improve the quality of the RF signal and ensure communication reliability, after the secondary network node receives the RF signal corresponding to its supported frequency band, it will forward the RF signal to the main network node. At this time, the main network node receives the RF signal from the terminal device corresponding to its own frequency. Then, it can perform a combining process on the RF signals of different frequencies carrying the same data to be transmitted, enhancing the intensity of the RF signals carrying the same data content, so as to accurately identify the data content of the data to be transmitted carried by the enhanced RF signal, that is, obtain the target transmission data.

[0083] Among them, regarding the communication protocol based on which the terminal device sends uplink data to the core network by accessing the main network node and at least one secondary network node, reference can be made to the Figure 3 heterogeneous frequency HPUE function implementation process shown above. The embodiments of the present application will not elaborate on this here.

[0084] In summary, in the embodiments of the present application, without increasing any hardware costs for the terminal device, the requirements for the linearity index of the PA of the terminal device and the index requirements for the TXSAW output by the PA are reduced to lower the hardware cost and improve the quality of the RF signal. The control terminal device will enter the heterogeneous frequency transmission mode, and the terminal device will respectively access the main network node and at least one secondary network node to form at least two uplink communication links. For any data to be transmitted, the terminal device will obtain multiple RF signals of different frequencies carrying the same data to be transmitted, and send them to the main network node and the secondary network node configured with the corresponding frequencies. The secondary network node will forward the received RF signal to the main network node, and the main network node will perform a combining process on these multiple RF signals of different frequencies received, accurately obtaining the target transmission data transmitted by the terminal device, ensuring the reliability and accuracy of the uplink data transmission of the terminal device.

[0085] Refer to Figure 5, which is a schematic flowchart of another optional example of the communication processing method proposed in this application. This embodiment can be a description of an optional refined implementation method of the communication processing method described in the above embodiments, and this refined embodiment is still described from the perspective of the terminal device, but is not limited to this refined implementation method. For example, Figure 5 As shown, the method may include:

[0086] Step S51, determine that the condition for different-frequency transmission is met, and send an access request message to the secondary network node corresponding to the signal coverage area to which the terminal device belongs;

[0087] In the embodiments of this application, the above-mentioned condition for different-frequency transmission may include but is not limited to: the communication area where the terminal device is located belongs to a weak field area of the wireless communication network, such as the terminal device moves to the edge position of the serving cell, etc.; support the terminal device to implement the different-frequency high-power user equipment (HPUE) function. Among them, in this different-frequency HPUE function, the terminal device supports the different-frequency transmission mode, and the primary network node supports uplink different-frequency reception. That is to say, this different-frequency HPUE function requires the cooperation of the terminal device and the primary network node to implement, and the implementation process can refer to the description of the corresponding embodiments below, and this embodiment will not be elaborated here.

[0088] As described in the above content of the condition for different-frequency transmission, when the condition for different-frequency transmission is met in the current communication environment of the terminal device, in order to ensure the communication quality, it is necessary to control the terminal device to switch from the single-frequency transmission mode to the different-frequency transmission mode, so that it can transmit multiple radio frequency signals of different frequencies for the same data to be transmitted. It can be seen that in order to support the terminal device to enter the different-frequency transmission mode to work, the terminal device needs to establish a corresponding number of multiple uplink communication links with the network side. That is to say, in addition to the one uplink communication link formed by the terminal device accessing the primary network node, at least one secondary network node needs to be accessed to form other uplink communication links.

[0089] Based on this, when the terminal device needs to enter the different-frequency transmission mode, it can send an access request message to the secondary network node corresponding to the signal coverage area to which it belongs to request access to this secondary network node and expand the uplink communication link of the terminal device. This application does not limit the content of this access request message and its communication transmission method, and can implement the message transmission between the terminal device and the network node according to the communication network type and the communication protocol it follows, etc. This embodiment will not be elaborated here.

[0090] In the actual application of this application, after receiving the above access request message, the secondary network node can parse the access request message to obtain message content such as the device identifier of the terminal device, and thus determine whether to allow the terminal device to access the secondary network node. In this implementation process, limited by information such as the network resources of the secondary network node itself and the maximum load it can support, as well as the access device management requirements of the entire communication processing system for the secondary network node, these information can be combined to determine whether to allow the terminal device to access. This application does not elaborate on this implementation process.

[0091] Step S52: Receive the access response message feedback by the secondary network node and access the secondary network node;

[0092] In the embodiment of this application, when the terminal device needs to enter the inter-frequency transmission mode, it can send an inter-frequency transmission application message to the control node on the network side. The control node determines that the inter-frequency transmission condition is met and allows the terminal device to access at least one secondary network node to support it in completing the inter-frequency transmission of multiple radio frequency signals carrying the same data to be transmitted. For this result, the control node can, based on the X2 interface between the primary network node and each secondary network node, send an access indication message for this terminal device to the corresponding secondary network node, or the primary network node can, based on the inter-frequency transmission support response message for this terminal device sent by the control node, send an access indication message for this terminal device to the connected secondary network node to indicate that the secondary network node is allowed to access this terminal device. This application does not limit the content and representation method of this access indication message.

[0093] In this way, after the secondary network node receives the access request message sent by any terminal device, it can determine whether to access this terminal device according to the content of the obtained access indication message. If it allows access to this terminal device, it can feedback a corresponding access response message to this terminal device. When the terminal device receives this access response message, it can access this secondary network node, but it is not limited to this implementation method for the terminal device to request access to the secondary network node.

[0094] It can be understood that if the above secondary network node determines not to allow access to this terminal device based on the access indication message, it can feedback a rejection access message to this terminal device. The terminal device can accordingly send an access application message for this secondary network node to the primary network node to apply for access to this secondary network node. When obtaining the access authorization of this secondary network node, the primary network node can re-send an access indication message to this secondary network node. After that, the terminal device can request access to this secondary network node according to the above method. Optionally, in the case where the secondary network node does not allow access to this terminal device, it can also apply for access to other secondary network nodes, and the implementation process is similar. This application embodiment does not elaborate on this here.

[0095] Step S53: Through negotiation between the terminal device and the accessed primary network node and secondary network node respectively, different frequencies at which the terminal device transmits data to the primary network node and the secondary network node are obtained.

[0096] Since each network node in the communication processing system can support a single frequency band, and the frequency bands supported by different network nodes can be different or there can be some overlapping frequency bands to ensure that a terminal device at any location can access at least one network node to meet the communication requirements of the terminal device, the present application does not limit the frequency bands supported by each network node, and can be determined according to information such as the network configuration parameters possessed by the network node itself.

[0097] Based on this, in the case where the terminal device accesses the primary network node and the secondary network node, in order to support subsequent different-frequency transmission of the same data to be transmitted by the terminal device, multiple frequencies based on which the terminal device transmits data can be determined based on information such as the transmission frequency band supported by the terminal device, the frequency band supported by the network node itself, and the occupied frequency band. That is, during the negotiation process between the terminal device and the primary network node and the secondary network node, multiple transmission frequencies for the terminal device can be determined based on information such as the supported frequency bands and idle frequency bands of each device, but it is not limited to this method of determining the transmission frequency.

[0098] It should be understood that during the negotiation process between the terminal device and the primary network node or the secondary network node, multiple transmission frequencies of the current terminal device can be determined through multiple message interactions, and the present application does not elaborate on the message interaction method and implementation process.

[0099] Step S54: According to the different frequencies, adjust the configuration parameters of multiple power amplifiers in the terminal device.

[0100] Step S55: Control multiple power amplifiers with the adjusted configuration parameters to process the same data to be transmitted respectively, and obtain multiple radio frequency signals with different frequencies.

[0101] For the data to be transmitted by the terminal device, usually after being modulated by a data modem, the radio frequency transceiver converts the modulated data into a radio frequency signal to be transmitted. Then, in order to be able to transmit at different frequencies, different configured power amplifiers can process the same data to be transmitted respectively. After the terminal device obtains multiple different frequencies (i.e., transmission frequencies) for the data to be transmitted, the configuration parameters of multiple power amplifiers with the same quantity can be adjusted respectively according to these multiple different frequencies, so that each power amplifier processes the input data to be transmitted and can obtain a radio frequency signal of one frequency. The present application does not elaborate on the implementation method of how to adjust the configuration parameters of the power amplifier so that it can perform power amplification processing on the input data and obtain a radio frequency signal of a certain frequency.

[0102] Step S56: Transmit multiple RF signals with different frequencies to the primary network node and the secondary network node configured with corresponding frequencies, so that the secondary network node transmits the received RF signals to the primary network node, and the primary network node performs a combining process on the multiple received RF signals with different frequencies to obtain target transmission data.

[0103] Following the above analysis, by using multiple power amplifiers with different configuration parameters to process the same data to be transmitted respectively, multiple RF signals with different frequencies can be obtained, and these multiple RF signals carry the same content of the data to be transmitted. Subsequently, transmitters such as antennas supporting multiple frequency bands can simultaneously transmit the RF signals output by the multiple power amplifiers at the multiple determined frequencies. Then, the signal receivers (such as at least one antenna) of the above-mentioned primary network node and secondary network node can detect the RF signals within the supported frequency bands existing within their respective signal coverage ranges.

[0104] Exemplarily, if the terminal device can simultaneously transmit RF signals carrying the same data to be transmitted at the first frequency and the second frequency, where the first frequency belongs to the frequency band supported by the primary network node and the second frequency belongs to the frequency band supported by the secondary network node, then the primary network node can obtain the RF signal at the first frequency, and the secondary network node can obtain the RF signal at the second frequency. The secondary network node forwards it to the primary network node through the X2 interface, and the primary network node performs an alignment and combining process on the RF signal at the first frequency and the RF signal at the second frequency to enhance the signal strength of the RF signal carrying the data to be transmitted and reliably and accurately obtain the target transmission data.

[0105] In summary, in the embodiments of the present application, when the terminal device meets the condition of different-frequency transmission and sends the data to be transmitted to the network side, in order to improve the communication quality and ensure the reliability and accuracy of data transmission, on the basis of the terminal device accessing the primary network node, the terminal device can also access the secondary network node corresponding to the signal coverage range to which it belongs, so that the terminal device forms multiple uplink communication links. After negotiating and determining the frequencies at which the terminal device transmits data through different uplink communication links, the terminal device can obtain multiple RF signals with different frequencies carrying the same data to be transmitted through multiple power amplifiers, and simultaneously transmit them to the primary network node and the secondary network node supporting the corresponding frequency bands. Then, the secondary network node sends the received RF signals to the primary network node, so that the primary network node obtains multiple RF signals with different frequencies carrying the same data to be transmitted. After combining processing, the signal strength of the RF signal is increased to accurately obtain the target transmission data that the terminal device needs to upload.

[0106] It can be seen that the inter-frequency HPUE provided by the communication processing method proposed in this application reduces the requirements for the linearity index of the PA and the requirements for index parameters such as the power capacity and temperature drift of the peripheral SAW, and does not increase the hardware cost of the terminal device.

[0107] Referring to Figure 6 , which is a signaling flow diagram of another optional example of the communication processing method proposed in this application. This method can describe another optional refined implementation manner of the communication processing method proposed in the above embodiment. For example, Figure 6 As shown, the method may include:

[0108] Step S61, the terminal device accesses the main network node;

[0109] In the embodiment of the present application, to ensure the basic communication requirements of the terminal device, after the terminal device enters the mobile communication network, it will request to access the mobile communication network. After the access request is verified to be qualified, it will usually access the main network node of the mobile communication network. The implementation process of how the terminal device accesses the main network node (i.e., the network attachment process of the terminal device) is not described in detail in this embodiment.

[0110] Step S62, the terminal device sends a transmission request message including inter-frequency transmission request information for the data to be transmitted to the main network node;

[0111] Step S63, the main network node transmits the inter-frequency transmission request information to the control node;

[0112] When the terminal device transmits data uplink, in order to improve the signal quality, especially in a weak field communication environment, the inter-frequency HPUE function of the terminal device can be used for data transmission. For this reason, to ensure the reliability of inter-frequency transmission, the terminal device can first apply for inter-frequency transmission to the network side, and the network side control node determines whether to support the terminal device to adopt the inter-frequency transmission mode. Therefore, the terminal device can send inter-frequency transmission request information to the control node through the main network node to request to adopt the inter-frequency transmission mode to realize the transmission of the subsequent data to be transmitted.

[0113] Among them, the above inter-frequency transmission request information may include the device identifier of the terminal device itself, location information, network configuration parameters, inter-frequency transmission request, etc. After the main network node forwards the inter-frequency transmission request information to the control node, the control node can also obtain information such as the node identifier of the main network node accessed by the terminal device, so that the control node can determine whether the terminal device and the main network node support inter-frequency transmission based on this. This application does not limit the content of the above inter-frequency transmission request information and the transmission method of the transmission request message composed of it, and it can be determined according to the situation.

[0114] Step S64: The control node responds to the inter-frequency transmission request information, determines that the terminal device meets the inter-frequency transmission condition, and generates an inter-frequency transmission support response message.

[0115] Step S65: The control node feeds back the inter-frequency transmission support response message to the primary network node.

[0116] When the control node receives the inter-frequency transmission request information reported by the primary network node, it can obtain the device identifier of the terminal device requesting inter-frequency transmission, the node identifier of the primary network node, and may even include information such as the node identifier of the secondary network node to which the terminal device requests access. Subsequently, based on the obtained device identifier / node identifier, it can query the radio capabilities of the corresponding terminal device and network node, determine whether the terminal device supports the ENDC function, whether the primary network node supports uplink inter-frequency reception function, and further determine whether to support the inter-frequency transmission of the terminal device, that is, whether to support inter-frequency HPUE. This application does not limit the implementation method of how the control node learns the radio capabilities of the terminal device and network node respectively.

[0117] Optionally, each time the terminal device camps on the network, the terminal device can report its radio capabilities, enabling the control node in the mobile communication network to timely learn the latest radio capabilities of the terminal device. In this way, when the terminal device requests to transmit uplink data, it can determine whether to use the single-frequency transmission mode or the inter-frequency transmission mode based on the known radio capabilities of the terminal device and network node, and send uplink data to the network side to ensure the reliability and accuracy of uplink data transmission and improve the signal quality.

[0118] In some other embodiments, the terminal device generally supports the single-frequency transmission mode, that is, the terminal device sends one or more radio frequency signals (i.e., uplink data) of the same frequency through an uplink communication link established with the primary network node. Therefore, in this embodiment, when the terminal device needs to start the inter-frequency transmission mode, the control node can verify whether the terminal device and the primary network node support inter-frequency HPUE in accordance with but not limited to the manner described above, and accordingly respond to the inter-frequency transmission request message from the terminal device. This application does not limit the query method and execution stage of the radio capabilities of the terminal device and network node, including but not limited to the several implementation methods described in the context, and can be flexibly determined according to the actual situation.

[0119] The control node determines that the terminal device meets the condition for inter-frequency transmission according to the method described above. In the case of supporting inter-frequency transmission, a corresponding response message for supporting inter-frequency transmission can be generated and fed back to the main network node to inform the main network node that the terminal device requesting inter-frequency transmission this time can enter the inter-frequency transmission mode. In some embodiments, the main network node can also determine, from the response message for supporting inter-frequency transmission, the secondary network node to which the terminal device requesting inter-frequency transmission this time can be connected, so as to subsequently instruct the secondary network node to allow the terminal device to access, etc. This application places no restrictions on the content and representation of the above response message for supporting inter-frequency transmission.

[0120] Step S66: The main network node responds to the response message for supporting inter-frequency transmission and determines the secondary network node corresponding to the signal coverage area to which the terminal device belongs;

[0121] In the actual application of this application, the secondary network node corresponding to the signal coverage area to which the terminal device belongs can be actively reported by the terminal device when requesting inter-frequency transmission, or determined by the control node when determining that the terminal device supports inter-frequency transmission, or determined by the main network node after learning that the terminal device supports inter-frequency transmission, based on the connection relationship between the network nodes in the access network and the position relationship between the terminal device and each network node, etc. The implementation method of step S66 can be flexibly determined according to communication requirements.

[0122] Step S67: The main network node sends an access indication message to the secondary network node;

[0123] Step S68: The main network node feeds back an inter-frequency transmission indication message for the secondary network node to the terminal device;

[0124] Step S69: The terminal device sends an access request message to the secondary network node;

[0125] Step S610: The secondary network node responds to the access request message according to the access indication message and feeds back an access response message to the terminal device;

[0126] Step S611: The terminal device receives the access response message and accesses the secondary network node;

[0127] In the case of determining that the terminal device supports inter-frequency transmission, based on the X2 connection method between the main network node and each secondary network node, the main network node can send an access indication message to the secondary network node corresponding to the signal coverage area to which the terminal device belongs, so as to instruct the secondary network node to respond to the access request message of the terminal device and allow the terminal device to access the secondary network node.

[0128] In the embodiments of the present application, the master network node can inform the terminal device that it can initiate inter-frequency HPUE by means of feeding back an inter-frequency transmission indication message to the terminal device, and at the same time, it can also inform the terminal device of the secondary network node that the terminal device can access to implement the inter-frequency HPUE. In this way, the terminal device can send an access request message to the secondary network node in a targeted manner to request access to the secondary network node.

[0129] In still some other embodiments, the inter-frequency transmission indication message fed back by the master network node can also be only used to inform the terminal device that it supports inter-frequency transmission. After that, the terminal device itself determines the secondary network node corresponding to its signal coverage area, and then sends an access request message to the secondary network node. Optionally, when the terminal device needs to enter the inter-frequency transmission mode, the access request message can also be directly sent to the secondary network node corresponding to its signal coverage area, and wait for the secondary network node to determine whether to allow the terminal device to access according to but not limited to the method described above. The implementation process is not described in detail in this application.

[0130] Step S612, the terminal device simultaneously transmits radio frequency signals of multiple different frequencies carrying the same data to be transmitted;

[0131] In the case where the terminal device accesses the master network node and at least one secondary network node respectively according to but not limited to the method described above to form multiple uplink communication links, for any data to be transmitted, the terminal device can obtain radio frequency signals of multiple different frequencies, and the data to be transmitted carried by these multiple radio frequency signals is the same. These multiple radio frequency signals are simultaneously transmitted through one or more antennas. The implementation process can refer to the corresponding part of the context embodiments, and is not described in detail in this embodiment.

[0132] Step S613, the master network node receives the radio frequency signal of the corresponding frequency transmitted by the terminal device;

[0133] Step S614, the secondary network node receives the radio frequency signal of the corresponding frequency transmitted by the terminal device;

[0134] In the embodiments of the present application, the master network node and each secondary network node in the mobile communication network can support a single frequency band. In this way, for the multiple radio frequency signals simultaneously transmitted by the terminal device at different frequencies (including the frequency band supported by the master network node and the frequency bands supported by at least one secondary network node), a network node supporting the corresponding frequency band can receive one radio frequency signal. The implementation process of how the network node obtains the radio frequency signal transmitted by the terminal device is not described in detail in this application.

[0135] Step S615, the secondary network node forwards the received radio frequency signal to the master network node through the X2 interface;

[0136] Step S616, the main network node combines the multiple RF signals of different frequencies carrying the same data to be transmitted received, and obtains the target transmission data.

[0137] Referring to Figure 3 the network structure shown, since the frequencies of the RF signals received by the main network node and the secondary network node from the terminal device are different, in the current communication environment, the quality of the RF signals received by these two network nodes is often different. However, since the data to be transmitted carried by the multiple RF signals is the same, the main network node aligns and combines these multiple RF signals, which can increase the signal strength of the RF signals corresponding to each content carrying the data to be transmitted. Compared with the RF signal directly received by the main network node, the signal quality of the combined RF signal is improved, and the target transmission data of the terminal device can be reliably and accurately obtained subsequently, ensuring the communication quality.

[0138] It can be seen that the different-frequency HPUE used by the terminal device in this application is formed by multiple TX transmission channels. The network side combines the RF signals of different frequencies carrying the same data to be transmitted, improving the signal quality. On the basis of ensuring the communication quality, the linearity requirement for the power amplifier PA and the index requirement for the peripheral SAW are reduced. For example, the 26dB requirement for realizing HPUE can be reduced by 3dB, solving the problem that increasing these index requirements leads to an increase in the hardware cost of the terminal device.

[0139] Referring to Figure 7 , which is a schematic flowchart of another optional example of the communication processing method proposed in this application. This embodiment can describe an optional implementation method for determining the condition for different-frequency transmission in the communication processing method described in the above embodiment. For other implementation steps of this communication processing method, reference can be made to the corresponding parts of the above embodiment, and this embodiment will not be elaborated. As Figure 7 shown, the implementation method for determining the condition for different-frequency transmission proposed in this embodiment may include but is not limited to:

[0140] Step S71, the main network node sends a wireless capability query request message to the accessed terminal device;

[0141] Step S72, the terminal device responds to the wireless capability query request message and obtains its own wireless capability information;

[0142] Step S73, the terminal device sends the wireless capability information to the main network node;

[0143] Combined with the above description of the related content of the inter-frequency transmission conditions, the terminal device can report the capabilities of inter-frequency HPUE when camping on the network to determine whether the terminal device supports ENDC, whether the main network node on the network side supports uplink inter-frequency reception, and can combine and process the received radio frequency signals of different frequencies to improve the quality of radio frequency signals. Therefore, after the terminal device camps on the network and accesses the main network node, in order to understand the radio capabilities of the terminal device, such as the list of supported frequencies, carrier aggregation CA frequency band combinations, dual-connection DC carrier combinations, and other air interface resources, the main network node can send a radio capability query request message to the terminal device to request a query of the radio capabilities of the terminal device.

[0144] After receiving the radio capability query request message sent by the network side, the terminal device can determine the radio capability information it has according to its current configuration and then feedback it to the main network node. This application does not limit the content of the radio capability information and its query method, which can be determined according to the situation.

[0145] Step S74, the main network node determines the radio capability identifier for the terminal device based on the radio capability information;

[0146] Step S75, the main network node sends the radio capability identifier to the control node;

[0147] Step S76, the control node determines whether the terminal device supports the inter-frequency transmission mode and whether the main network node supports uplink inter-frequency reception based on the radio capability identifier, and generates an inter-frequency transmission capability indication message;

[0148] After obtaining the radio capability information of each accessed terminal device by the main network node according to the method described above but not limited to it, the main network node can generate corresponding radio capability identifiers (Indication Capability) and send them to the control node. The control node stores the radio capability information of each terminal device that has camped on the network. This application does not limit the storage method of the radio capability information of each terminal device.

[0149] In addition, for each network node of the mobile communication network, when joining the mobile communication network, the network node can report its own radio capability information (such as the supported frequency band list, the communication protocols it has, the radio resources it has, the radio resource usage situation, etc.) to the control node for storage, and at the same time can determine whether the network node supports the uplink inter-frequency reception function according to this. The implementation process is not described in detail in this application.

[0150] In a scenario where any terminal device requests to transmit data on a different frequency, after the control node receives the different-frequency transmission request message sent by the terminal device, it can query whether the terminal device supports the different-frequency transmission mode, that is, whether the terminal device supports ENDC, based on the wireless capability identifier of the terminal device. At the same time, the control node can also query whether the master network node supports uplink different-frequency reception, and then generate a different-frequency transmission capability indication message according to the query results to indicate whether the terminal device supports ENDC and whether the master network node supports uplink different-frequency reception. This application places no restrictions on the content and representation method of the different-frequency transmission capability indication message.

[0151] Step S77, the control node sends the different-frequency transmission capability indication message to the master network node;

[0152] Step S78, the master network node feeds back the different-frequency transmission capability indication message to the terminal device;

[0153] Step S79, the terminal device determines whether it supports the terminal device to implement the different-frequency HPUE function according to the different-frequency transmission capability indication message.

[0154] When the uplink service of the terminal device needs to perform uplink different-frequency HPUE and requests the different-frequency HPUE function from the network side according to the method described above, after the control node queries the wireless capability of the terminal device and the uplink data reception capability of the master network node, it can adopt the method of feeding back the different-frequency transmission capability indication message and forward it to the terminal device by the master network node. In this way, after the terminal device determines that it supports the terminal device to implement the different-frequency HPUE function according to the content of the different-frequency transmission capability indication message, it enters the different-frequency transmission mode. For any data to be transmitted, multiple radio frequency signals are simultaneously transmitted on different frequencies, and the secondary network node forwards one received radio frequency signal to the master network node, and the master network node combines and processes these multiple radio frequency signals with different frequencies to improve the signal quality.

[0155] In some other embodiments proposed in this application, in order to reduce the waste of air interface resources, after the terminal device camps on the network, the terminal device can actively report wireless capability information to the network side and store it in the control node (such as MME) for direct query when needed later; or, according to the method described above, the network node issues a wireless capability query request message to actively obtain the wireless capability information of the accessed terminal device and then send it to the control node for storage for subsequent query to determine whether the terminal device supports ENDC. This application places no restrictions on the implementation method of the wireless capability reporting of the terminal device and can be determined according to the situation.

[0192] Referring to Figure 10 , it is a schematic hardware structure diagram of an optional example of a computer device applicable to the communication processing method proposed in the present application. The computer device can be a terminal device or a network node, such as Figure 10 shown, the computer device may include: a communication module 101, at least one memory 102, and at least one processor 103, where:
