Detailed ways

Hereinafter, some of the terms in the embodiments of the present application will be described to facilitate understanding.

1) A terminal, also called a user equipment (UE), a mobile station (MS), or a mobile terminal (MT), is a voice/data connectivity provided to a user. Devices, for example, handheld devices with wireless connectivity, in-vehicle devices, and the like. Currently, some examples of terminals are: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality. (augmented reality, AR) equipment, wireless terminals in industrial control, wireless terminals in self driving, wireless terminals in remote medical surgery, smart grid Wireless terminals, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and the like.

2) The network device is a device that provides wireless services for the terminal, such as a radio access network (RAN) node. A RAN node is a node in a network that connects a terminal to a wireless network. Currently, some examples of RAN nodes are: gNB, transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), and Node B (Node). B, NB), base station controller (BSC), base transceiver station (BTS), home base station (for example, home evolved NodeB, or home Node B, HNB), baseband unit (baseband unit, BBU), or Wifi access point (AP), etc. In addition, in a network structure, the RAN includes a centralized unit (CU) node or a distributed unit (DU) node, in which the functional division on the RAN side is implemented in the CU and the DU, and A plurality of DUs are centrally controlled by one CU. At this time, the RAN node may be a CU node/DU node. The functions of the CU and the DU may be divided according to the protocol layer of the wireless network. For example, the function of the packet data convergence protocol (PDCP) layer is set in the CU, the protocol layer below the PDCP, for example, radio link control. , RLC) and media access control (MAC) functions are set in the DU. The division of the protocol layer is only an example, and can also be divided in other protocol layers, for example, in the RLC layer, the functions of the RLC layer and the above protocol layer are set in the CU, and the functions of the protocol layer below the RLC layer are set in the DU; Alternatively, in a certain protocol layer, for example, a part of the function of the RLC layer and a function of a protocol layer above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are set in the DU. In addition, it may be divided in other manners, for example, according to the delay division, the function that needs to meet the delay requirement is set in the DU, and the function lower than the delay requirement is set in the CU.

3) "Multiple" means two or more, and other quantifiers are similar. "/" describes the association relationship of the associated object, indicating that there can be three kinds of relationships. For example, A/B can indicate that there are three cases where A exists separately, A and B exist at the same time, and B exists separately.

Please refer to FIG. 1 , which is a schematic diagram of a dual connectivity (DC) scenario provided by an embodiment of the present application. As shown in FIG. 1 , the network device 110 and the network device 120 jointly provide services for the terminal 130. The network device 110 is a master node (MN), and the network device 120 is a secondary node (SN). The master node 110 and the core network (CN) 140 have a control plane connection and a user plane connection, and the secondary node 120 and the core network 140 may have a user plane connection or may not have a user plane connection, wherein the S1 is used. -U stands for user plane connection and S1-C stands for control plane connection. When there is no user plane connection between the secondary node 120 and the core network 140, the data of the terminal 130 may be offloaded by the primary node 110 to the secondary node 120 in a Packet Data Convergence Protocol (PDCP) layer. The primary node and the secondary node are also referred to as a primary base station and a secondary base station.

Dual connectivity can be implemented between network devices in the same frequency band or between network devices in different frequency bands. That is, the primary node and the secondary node can work in the same frequency band or in different frequency bands. The frequency band is a spectrum resource, and may be represented by a frequency point in the spectrum resource range (for example, a 3.5 GHz band), and the spectrum resource may include continuous spectrum resources, or may include discontinuous spectrum resources. For example, the frequency band may include an uplink frequency band and a downlink frequency band, and the uplink frequency band and the downlink frequency band may be two discontinuous spectrum resources. For a specific uplink frequency band combination, such as the 1.8 GHz band and the 3.5 GHz band, when the terminal performs uplink transmission on two frequency bands at the same time, a serious inter-modulation signal may cause interference to the downlink reception. It is called an inter-modulation product or inter-modulation degradation (IMD). At this time, the transmission of the terminal on the uplink frequency band of the primary node and the uplink frequency band of the secondary node may be staggered in a time division manner.

In addition, the dual connectivity may be implemented between intra-radio access technology (intra-RAT) network devices or between inter-RAT network devices. For example, a dual connection can be implemented in the scenario of joint networking of LTE (also referred to as 4G) and New Radio (NR) (also referred to as 5G), which is called LTE-NR dual connection, so that the terminal can simultaneously from LTE. And the NR air interface obtains wireless resources for data transmission, and obtains a gain of the transmission rate.

Take the LTE-NR dual connection as an example. Assume that the master node works in the LTE system and the working frequency band is 1.8 GHz. The secondary node works in the NR system and the working frequency band is the 3.5 GHz band. Alternatively, the master node works in the NR system, and the working frequency band is 3.5 GHz band, the secondary node works in the LTE system, and the working frequency band is the 1.8 GHz band. When the terminal sends uplink information to the primary node and the secondary node at the same time, a handover product is generated. When the handover product falls into the downlink frequency band of the LTE, the terminal will interfere with the downlink reception of the terminal in the LTE network, which may result in the terminal being incorrect. Receive downlink information, which affects communication quality.

To this end, the primary node and the secondary node do not perform uplink scheduling on the terminal at the same time, so that the terminal does not simultaneously transmit information in the 1.8 GHz LTE uplink frequency band and the 3.5 GHz NR uplink frequency band. That is, the scheduling of the uplink transmission of the terminal by the network side is staggered, and the offset may be a shift of the time division multiplexing (TDM) mode. Please refer to FIG. 2 , which is a schematic diagram of uplink scheduling in an LTE-NR dual connectivity scenario according to an embodiment of the present application. The uplink scheduling of the terminal by the master node (eg, operating in the LTE system) and the uplink scheduling of the secondary node (eg, operating in the NR system) to the terminal are staggered in the time domain. As shown in FIG. 2, the uplink transmission scheduling of the secondary node to the terminal is in the period of t0-t1 and t2-t3; the uplink transmission scheduling of the primary node to the terminal is in the period of t1-t2 and t3-t4. A simple implementation method is that the primary node and the secondary node both perform semi-persistent scheduling on the terminal, that is, the t0-t1 and t2-t3 periods are the same, and are set to the period T1; the times of t1-t2 and t3-t4 are the same, and the period is set to T2. . The secondary node schedules the uplink transmission of the terminal semi-statically with T1 as the periodicity; the primary node schedules the uplink transmission of the terminal semi-statically with T2 as the periodicity, where T1 and T2 do not overlap in the time domain, that is, staggered.

The above transmission mode is referred to as a first pattern. The first mode is a mode in which the first spectrum resource (or the first frequency band) and the second spectrum resource (or the second frequency band) are staggered in the time domain, that is, staggered for uplink transmission between the terminal and the first network device, and Uplink transmission between the terminal and the second network device. In other words, in the first mode, the uplink transmission of the terminal in the first spectrum resource (or the first frequency band) and the second spectrum resource (or the second frequency band) is staggered in the time domain. In other words, in the first mode, the scheduling of the uplink transmission of the terminal by the network device on the first spectrum resource (or the first frequency band) and the second spectrum resource (or the second frequency band) is staggered in the time domain. The first network device and the second network device jointly provide services for the terminal. The first spectrum resource and the second spectrum resource may be frequency bands in the same network standard, for example, different frequency bands in the LTE or NR system; or may be frequency bands in different network standards, such as different frequency bands in the LTE and NR systems.

In addition, LTE operates in the frequency band below 3 GHz. In order to introduce more spectrum resources, NR introduces spectrum resources higher than 3 GHz. When the NR works in the frequency band above 3 GHz, the uplink coverage of the NR will be weak, in order to enhance the uplink coverage of the terminal under the NR network device. A method for coexistence of LTE and NR is proposed. The low-frequency LTE uplink spectrum resource is shared with the NR. The terminal can send the NR uplink information to the NR network device through the LTE spectrum resource.

Please refer to FIG. 3 , which is a schematic diagram of LTE and NR being coexistent according to an embodiment of the present application. As shown in FIG. 3, it is assumed that one of the primary node and the secondary node is a network device working in the NR system, for example, a gNB in the NR network, and the other node is a network device in the working LTE system, for example, an LTE network. eNB in. The eNB works on the LTE spectrum resource, the downlink frequency band is F1, and the uplink frequency band is F2; the gNB works on the NR spectrum resource, the downlink frequency band is F3, and the uplink frequency band is F4. At this time, both the LTE network and the NR network can be a TDD system, allowing F1=F2 and F3=F4. For the terminal in the cell of the gNB, the terminal in the central area may still use the NR spectrum resource F4 to send the uplink information of the NR to the gNB; the terminal at the cell edge may send the uplink information of the NR to the gNB by using the LTE spectrum resource F2, because the spectrum The frequency of the F4 is higher and the attenuation is more serious. The terminal at the edge of the cell uses the NR spectrum resource F4 for uplink transmission, which may result in the degradation of the uplink information transmission quality or even the gNB.

At this time, on the LTE spectrum resource F2, LTE and NR are coexisting, or the spectrum resource F2 of LTE is shared by the LTE system and the NR system. In this case, the LTE network device and the NR network device use the spectrum resource F2 in common, and may use the same frequency resource at the same time, thereby causing interference to the transmission of the other party. Therefore, the mode of using the spectrum resource F2 can be negotiated between the two network devices, and the mode can be time-division, such as TDM, or frequency division, such as frequency division multiplexing (FDM).

The above transmission mode is referred to as a second pattern. The second mode is a mode in which the spectrum resource is shared by the first network device and the second network device, where the sharing is sharing of spectrum resources, that is, uplink transmission between the first network device and the terminal, and between the second network device and the terminal. The uplink transmission shares the spectrum resource. That is, the second mode may be a mode in which the first network device and the second network device stagger the uplink communication using the shared spectrum resource with the terminal. In other words, in the second mode, the terminal staggers and uses the shared spectrum resource to perform uplink transmission with the first network device and the second network device. The first network device and the second network device may be network devices of different standards. In this case, the second mode may be understood as a mode in which the first network standard and the second network standard share spectrum resources, and the spectrum resource is an uplink spectrum resource. For example, LTE uplink and NR uplink share LTE spectrum resources.

It can be seen that, in the DC scenario, when the primary node and the secondary node support the sharing of the spectrum resources, the interference between the network devices using different spectrum resources is reduced by setting two transmission modes, that is, the first mode and the second mode. The network side notifies the terminal of the information of the two modes of the transmission, so that the terminal can learn the information of the first mode and the second mode, and then adapt different spectrum resources in advance, reduce the delay of the uplink transmission, and improve the communication efficiency. Further, the information of the two transmission modes may be transmitted between the primary node and the secondary node on the network side, so that when the primary node or the secondary node performs scheduling on the terminal, resources may be configured for the terminal based on the two transmission modes, thereby improving Resource utilization reduces interference caused by resource usage conflicts.

Description will be made below with reference to the drawings.

Please refer to FIG. 4 , which is a schematic diagram of a communication method according to an embodiment of the present application. The communication method can be used in a communication system including a first network device and a second network device that collectively provide services to the terminal. The first network device may be a primary node, and the second network device may be a secondary node; of course, the first network device may be a secondary node, and the second network device may be a primary node. As shown in FIG. 4, the method includes the following steps:

S410: The information of the first mode/the information of the second mode is transmitted between the first network device and the second network device. The information of the first mode is used to indicate the first mode, and the information of the second mode is used to indicate the second mode, where the first mode is used for the first spectrum resource and the second spectrum resource are staggered in the time domain for the terminal and the first mode. An uplink transmission between the network devices and an uplink transmission between the terminal and the second network device, the second mode is used for uplink transmission between the terminal and the first network device, and uplink transmission sharing between the terminal and the second network device The first spectrum resource or the second spectrum resource.

The first mode and the second mode may both be determined by a network device, for example, both determined by the master node and transmitting information of the first mode and information of the second mode to the secondary node, or both determined by the secondary node and the first mode The information and the information of the second mode are sent to the master node. Alternatively, the first mode and the second mode are determined by different network devices, for example, the first mode is determined by the primary node and the information of the first mode is sent to the secondary node, and the second mode is determined by the secondary node and the information of the second mode is determined. Sending to the master node; or conversely, the first mode is determined by the secondary node and transmitting information of the first mode to the master node, and the second mode is determined by the master node and transmitting information of the second mode to the secondary node.

It can be seen that the information of the first mode/the second mode is transmitted between the first network device and the second network device, where the first network device sends the information of the first mode and the information of the second mode to the second network device; Or the second network device sends the information of the first mode and the information of the second mode to the first network device; or the first network device sends the information of the first mode to the second network device, where the second network device The information of the second mode is sent to the first network device; or the information of the second mode is sent by the first network device to the second network device, where the second network device sends the information of the first mode to the first network device. At this time, the first network device and/or the second network device acquire the information of the first mode and the information of the second mode, and thus may perform the following operations:

S420: Generate configuration information, where the configuration information includes information of the first mode and information of the second mode.

S430: Send configuration information to the terminal.

The secondary node may send the configuration information to the terminal through the primary node, or directly send the configuration information to the terminal. For example, if the second network device is a secondary node, the second network device sends the configuration information to the first network device, and the first network device encapsulates the configuration information in the configuration information generated by the first network device and sends the configuration information to the terminal.

After receiving the configuration information, the terminal may transmit the uplink information according to the configuration information, that is, perform the following step S440.

S440: Perform uplink transmission according to the configuration information. That is, the uplink information is sent to the network side, and the uplink information may be sent to the first network device or may be sent to the second network device.

The uplink information may include uplink data and/or uplink signaling, and the content of the application is not limited.

After receiving the configuration information, the terminal may determine, according to the information of the first mode and the second mode, which spectrum resources may be scheduled by the network side, so that the terminal may process in advance to adapt the baseband resource to the corresponding spectrum. Resources, thereby reducing the delay of uplink transmission and improving communication efficiency. The terminal may estimate, according to the historical resource scheduling situation, that the currently adopted transmission mode is the first mode or the second mode, so that the pre-processing is performed according to the estimated transmission mode. Alternatively, the terminal may perform pre-processing on both transmission modes, and adapt the baseband resources to the spectrum resources of the two modes. In addition, the network side can select the target mode notification terminal, and the terminal performs pre-processing according to the target mode, and adapts the baseband resource to the spectrum resource of the target mode. Thus, the processing complexity of the terminal can be reduced, and the delay is further reduced.

The terminal in the LTE-NR dual connection performs data transmission with the primary node and the secondary node at the same time. When the terminal sends uplink data to the NR network device, the terminal may pass the LTE spectrum resource or the NR spectrum resource. However, the terminal does not know when to send uplink information to the LTE network device, and when it will send uplink information to the NR network device, and can only monitor the scheduling information of the LTE network device and the NR network device at the same time. After receiving the scheduling information, the terminal can send the uplink information to the LTE network device or the NR network device on the corresponding time-frequency resource. It can be seen that, in the prior art, the terminal does not know when the network side performs scheduling on which resources, so it is necessary to always monitor the scheduling information of the primary node and the secondary node, and the power consumption is large. After the above solution is adopted, the terminal can understand the usage of the spectrum resources of the two transmission modes, thereby performing targeted monitoring and reducing power consumption.

The network side also sends scheduling information to the terminal, where the scheduling information is used to indicate time-frequency resources for uplink transmission. The scheduling information may be sent by the first network device or by the second network device. The performing uplink transmission by the terminal according to the configuration information includes: the terminal performs pre-processing according to the information of the first mode/the second mode to perform uplink transmission based on the scheduling information. For example, after the terminal learns the first mode and the second mode, according to the historical scheduling situation or the network side notification, determining that the first mode (or the second mode) is the current mode, the current mode is used for pre-processing to perform uplink transmission based on the scheduling information. .

The first mode may be referred to as a DC mode or a TDM mode or the like, and the second mode may be referred to as a shared mode or a coexistence mode or the like. These schema names are exemplary only and are not subject to any restrictions, and other names may be used.

Taking the LTE-NR joint networking as an example, the first mode may be a mode in which the LTE spectrum resource and the NR spectrum resource are staggered in the time domain; the second mode may be a mode in which the LTE uplink and the NR uplink share the LTE spectrum resource. At this time, two transmission modes are transmitted between the primary node and the secondary node: one transmission mode is a mode in which LTE spectrum resources and NR spectrum resources are staggered in the time domain; and the other is LTE uplink and NR uplink shared LTE spectrum resources. Mode.

For the first mode, at least one resource mode may be configured, where each resource mode is used to indicate a resource usage location of a first spectrum resource/second spectrum resource; the resource usage location may be a time domain location. For the second mode, at least one resource mode may be configured, where each resource mode is used to indicate a resource usage location of a shared spectrum resource, where the shared spectrum resource is an uplink transmission between the terminal and the first network device, and a terminal and The first spectrum resource or the second spectrum resource shared by the uplink transmission between the second network devices; the resource usage location may be a time domain location, a frequency domain location, or a time-frequency location.

Taking the LTE-NR joint networking as an example, the resource mode of the first mode may be used to indicate an uplink time domain position of the NR spectrum resource in the first mode, that is, an uplink available timing; that is, a resource of the first mode. The mode may be used to indicate a time domain location or time at which the terminal may perform uplink transmission when the NR network device communicates with the terminal using the NR spectrum resource. The time domain location may be embodied, for example, in the form of a frame, a subframe, a slot, or a symbol. For different Numerology (also known as air interface resource configuration), the time domain size of the frame, subframe, slot, or symbol may be the same or different. The different Numerology means that the air interface parameter has multiple configurations, and the air interface parameter includes, for example, the following parameters: the frequency domain length of the resource element (RE), that is, the subcarrier spacing; the time domain length of the RE, that is, the orthogonal frequency division complex The length of time of the (orthogonal frequency division multiplexing, OFDM) symbol; the number of time resource units in the scheduling time unit; or the cyclic prefix (CP) type of the OFDM symbol, and the like.

The foregoing is only an example. Optionally, the resource mode of the first mode may be used to indicate an uplink time domain location of the LTE spectrum resource in the first mode, that is, an uplink available timing; that is, a resource mode of the first mode. It can be used to indicate a time domain location or time when the terminal can perform uplink transmission when the LTE network device and the terminal use the LTE spectrum resource for communication. Then the time domain location outside the time domain location can be used for communication between the NR network device and the terminal using NR spectrum resources. Alternatively, the resource mode of the first mode may be used to indicate an uplink time domain location of the LTE spectrum resource and an uplink time domain location of the NR spectrum resource in the first mode.

Taking the LTE-NR joint networking as an example, the resource mode of the second mode may be used to indicate a resource location between the NR network device and the terminal in the second mode for uplink transmission using the LTE spectrum resource. The resource location is, for example, a time domain location, and may be embodied in the form of a frame, a subframe, a slot, or a symbol. Or the resource location may be a frequency domain location, and may be embodied in the form of frequency, bandwidth, and the like. Or the resource location may be a time-frequency location, and may be embodied in the form of a physical resource block (PRB), a PRB pair, or a resource block group (RBG).

Optionally, the resource modes for the two transmission modes may be pre-designed, and then a resource mode is selected for communication according to requirements. The demand may be a demand for the first spectrum resource/second spectrum resource of the service type. For example, for the first mode, at least one resource mode may be pre-designed, and the first network device (or the second network device) may configure the first mode to adopt one of the resource modes, and the first mode indicating the resource mode The information is sent to the second network device (or the first network device). For the second mode, at least one resource mode may be pre-designed, and the first network device (or the second network device) may configure the second mode to adopt one of the resource modes, and information indicating the second mode of the resource mode Send to the second network device (or the first network device).

Alternatively, the resource mode for the two transmission modes may be configured by the first network device/second network device according to requirements. The demand may be a demand for the first spectrum resource/second spectrum resource of the service type. For example, for the first mode, the first network device (or the second network device) may configure a resource mode adopted by the first mode, and send information indicating the first mode of the resource mode to the second network device (or the first Network equipment). For the second mode, the first network device (or the second network device) may configure the resource mode adopted by the second mode, and send information indicating the second mode of the resource mode to the second network device (or the first network device) ).

The information of the first mode may be used to indicate one resource mode of the first mode; the information of the second mode may be used to indicate a resource mode of the second mode. For each transmission mode, there may be a corresponding index or identification (ID) to indicate the transmission mode, for example, the index of the first mode is “0”; the index of the second mode is “1”. For the resource mode of the first mode or the second mode, there may be corresponding configuration information to indicate the resource mode. For example, M resource modes of the first mode and resource modes of N of the second mode are pre-configured, wherein M and N are positive integers. Each resource mode has a corresponding number or index, such as 0 to M-1 or 1 to M, 0 to N-1 or 1 to N. The first network device (or the second network device) configures the resource mode of the first mode to be a resource mode corresponding to the number “X”, and sends the number “X” to the second network device (or the first network device), where X ∈[0,M-1] or [1,M]. And the first network device (or the second network device) configures the resource mode of the second mode to be a resource mode corresponding to the number “Y”, and sends the number “Y” to the second network device (or the first network device), where Y∈[0,N-1] or [1,N].

The two types of transmission modes are configured by the first network device, and the information of the two transmission modes is sent to the second network device. For example, the information of the transmission mode may be:

Pattern List

Pattern ID/index[0,1]

Pattern Configuration[X,Y]

Alternatively, the first mode is referred to as a DC pattern, and the second mode is referred to as a sharing pattern. The form of the information of the transmission mode may be, for example:

DC pattern【0】

Configuration【X】

Sharing pattern【1】

Configuration【Y】

It can be seen that the information of the first mode may include a part for indicating the first mode, and may further include a part for indicating a resource mode of the first mode; the information of the second mode may include a part for indicating the second mode, and A portion for indicating a resource mode of the second mode may be included. The form of the above cells is merely an exemplary reference and is not intended to limit the application.

Optionally, the network side may configure the terminal to perform measurement on the cell of the first network device/the second network device. The terminal performs measurement based on the configuration on the network side and reports the measurement result. The measurement result may include, for example, reference signal received power (RSRP) or reference signal received quality (RSRQ). The network side may select the first mode or the second mode as the target mode based on the measurement result. The measurement result may include a measurement result of a cell under the first network device/a measurement result of a cell under the second network device. When the first network device is the master node, the terminal may report the measurement result to the first network device, where the first network device may send all or part of the measurement result to the second network device, so that the second network device determines the target mode, or The target mode can be determined by the first network device based on the measurement results. When the second network device is the master node, the terminal may report the measurement result to the second network device, where the second network device sends all or part of the measurement result to the first network device, so that the first network device determines the target mode, or The target mode is determined by the second network device based on the measurement result. It can be seen that the network device that generates the configuration information and the network device that determines the target mode may be the same network device or different network devices.

Further, the network device that determines the target mode may send the indication information of the target mode to the terminal, and the terminal receives the indication information of the target mode, and may obtain the target mode determined by the network side, thereby pre-adapting the use of the spectrum resource by the target mode. Reduce the delay of uplink transmission and improve communication efficiency. The network device that determines the target mode may directly send the indication information of the target mode to the terminal, or may send the indication information to the terminal through another network device. For example, the first network device determines the target mode, and sends the indication information of the target mode to the terminal directly or through the second network device. The indication information of the target mode is used to indicate the target mode.

Optionally, the foregoing configuration information and the indication information of the target mode may be carried in the same message, for example, in a radio resource control (RRC) message. That is, the first mode and the second mode are configured by the same message to the terminal, and which mode is activated in the same message.

The network side may also not send the indication information of the target mode to the terminal, but activate one of the modes by default, for example, the first mode or the second mode is activated by default.

Optionally, the foregoing configuration information and the indication information of the target mode are sent to the terminal in different messages. For example, the foregoing configuration information is carried in the RRC message, and the indication information of the target mode is carried in the media access control (MAC). In the layer message, for example, a media access control control element (MAC CE). That is, the network side configures the first mode and the second mode to the terminal through the upper layer, and indicates to the terminal which mode is activated by the MAC layer. Compared with the RRC configuration, the MAC layer message indicates that the target mode can implement the uplink spectrum resource conversion more quickly, and then the terminal sends the uplink information on the specific time-frequency resource according to the network-side-based scheduling. The network device that sends the configuration information and the activation indication information may be the same network device or different network devices.

The primary node may send the measurement information to the secondary node during the secondary node addition process to save the number of messages.

In addition, when the primary node determines the information of the first mode/the information of the second mode, the information of the first mode/the information of the second mode may be sent in the process of establishing the secondary node or the interface between the primary node and the secondary node. Give the secondary node. When the secondary node determines the information of the first mode/the information of the second mode, the information of the first mode/the information of the second mode may be sent to the primary in the secondary node adding process or the interface establishing process between the primary node and the secondary node. node.

In another implementation, the network side may directly configure the target mode used by the terminal, so that the terminal performs uplink transmission according to the target mode. At this time, the first network device or the second network device on the network side generates configuration information, where the configuration information includes information of a target mode, where the information of the target mode is used to indicate a resource mode of the target mode. Then, the network side sends the uplink scheduling information, where the uplink scheduling information is used to indicate the time-frequency resource of the uplink transmission. The terminal receives the configuration information, determines the target mode according to the information of the target mode, performs pre-processing, and performs uplink transmission by using the time-frequency resource indicated by the uplink scheduling information.

In a further implementation, the first mode/second mode information may not be transmitted between the first network device and the second network device on the network side, but the first mode information/second mode determined by itself is respectively determined. The information is sent to the terminal. Therefore, the terminal may perform pre-processing according to the information of the first mode and the information of the second mode, to perform uplink transmission when the uplink scheduling information is subsequently received.

The cells in the above configuration information may be located in the same message or in different messages, and the application is not limited.

Optionally, the first network device and the second network device may further transmit capability information, where the capability information is used to indicate that the first network device/the second network device supports the second mode, that is, whether the second mode is supported. . The support capability of the second mode may also be referred to as uplink sharing capability. For example, the first network device sends the first capability information to the second network device, where the first capability information is used to indicate that the first network device supports the second mode. For another example, the second network device sends the second capability information to the first network device, where the second capability information is used to indicate that the second network device supports the second mode. Furthermore, the first network device and the second network device can interact with each other, that is, the first network device sends the first capability information to the second network device, and the second network device sends the capability information to the first network device.

In this way, the first network device and the second network device can know the support capability of the other party for the second mode. When the second mode is not supported by either party, the interaction between the two modes can not be performed to save the operation process. Of course, the first network device and the second network device may support the second mode by default and perform the operations in the above embodiments.

Optionally, the terminal may also notify the network side of the support capability of the second mode. For example, the terminal sends the third capability information to the primary node, where the third capability information is used to indicate the terminal's support capability for the second mode. The support capability of the second mode may also be referred to as uplink sharing capability.

In this way, when the network side knows that the terminal does not support the second mode, the network may not perform the interaction of the subsequent two transmission modes for the terminal to save the operation process. Of course, the network side can default to all terminals supporting the second mode and perform the operations in the above embodiments.

Optionally, due to the change of the terminal service or the movement of the location, the network side may replace the transmission mode configured to the terminal, that is, replace the target mode, so as to better adapt to the current service or location of the terminal. At this time, the above communication method may further include the steps shown in FIG. 5. Please refer to FIG. 5 , which is a schematic diagram of a communication method according to an embodiment of the present application. The method is used to replace a target mode, including the following steps:

S510: The first network device determines a replacement target mode.

For example, the first network device may maintain a policy of replacing the target mode, such as a change in terminal location, moving from the cell edge to the cell center, changing the target mode from the second mode to the first mode; or moving from the cell center to the cell edge, The target mode is changed from the first mode to the second mode. The first network device may determine whether to replace the target mode according to the measurement information reported by the terminal. When you are sure to change the target mode, do the following:

S520: The first network device sends modification request information to the second network device, where the modification request information is used to request to modify the target mode.

When the first network device is a secondary node, the modification request information may be carried in an existing secondary node modification request message.

S530: The second network device sends the modification confirmation information to the first network device.

After receiving the modification request information, the second network device may learn the new target mode, reserve resources according to the new target mode, and return the modification confirmation information to the first network device. The modification confirmation information may be carried in an existing secondary node modification confirmation message.

S540: The network side sends a replacement indication, where the replacement indication is used to indicate that the terminal replaces the target mode. For example, the original transmission mode is the first mode, and the indication is used to instruct the terminal to replace it with the second mode. Alternatively, the original transmission mode is the second mode, and the indication is used to instruct the terminal to replace it with the first mode.

The replacement indication may be sent by the first network device or by the second network device.

Optionally, the first network device may send the replacement indication by using an RRC message, or may carry the replacement indication by using a MAC layer message. The replacement indication may be indication information of a mode to be activated.

In the above embodiment, the first network device determines the replacement target mode as an example. Similarly, the second network device may also determine the replacement target mode. This application is not limited. In addition, the first network device may be a primary node or a secondary node. That is, the replacement target mode may be determined by the primary node, or the replacement target mode may be determined by the secondary node. When the primary node determines the replacement target mode, the primary node notifies the secondary node of the changed mode, and may have the primary node or the secondary node notifying the terminal of the changed mode. When the secondary node determines the replacement target mode, the secondary node notifies the primary node of the changed mode, and may have the primary node or the secondary node notifying the terminal of the changed mode.

It can be seen that the replacement of the target mode can be triggered by the primary node or by the secondary node. And the indication information may be sent by the primary node to the terminal, or may be sent to the terminal by the secondary node (directly or through the primary node). In addition, the replacement indication may be sent to the terminal through a high-level message, such as an RRC message, or may be sent to the terminal through a MAC layer message, such as a MAC CE.

Optionally, after the first network device (or the second network device) determines the information of the first mode/the second mode, the first mode/the second mode may also be modified, mainly referring to modifying the first mode/second mode. The resource mode of the pattern. And transmitting the modified information of the first mode/second mode to the second network device (or the first network device). At this time, the above communication method may further include the steps shown in FIG. 6. Please refer to FIG. 6 , which is a schematic diagram of a communication method according to an embodiment of the present application, where the method is used to modify a first mode/second mode. In this embodiment, the first network device determines the first mode, and determines to modify the second mode as an example, including the following steps:

S610: The first network device determines to modify the first mode.

Modifications here may refer to modifications to the resource pattern. For example, the first network device determines to adjust the resource mode of the first mode from one resource mode to another. It may be a modification of the location of the resource, or it may be a modification of the granularity of the time division, for example from a sub-frame level to a symbol level or a slot level.

S620: The first network device sends modification request information to the second network device, where the modification request information is used to request to modify the first mode.

The modification request information may include information of the first mode for indicating a resource mode of the modified first mode.

S640: The second network device sends the modification confirmation information to the first network device.

The second network device modifies the configuration of the first mode, that is, the resource mode of the first mode, according to the modification request information. In addition, step S630 may be further included: the second network device makes a decision to determine whether to modify the target mode. If the target mode is modified, the information of the target mode to be activated may be carried in the modification confirmation information.

S650: The network side sends a modification indication, where the modification indication is used to instruct the terminal to modify the resource mode of the first mode.

If the second network device determines the modification target mode in step S630, the network side may use the method of sending the target mode in the above embodiment to send the target mode to be activated to the terminal.

The modification indication may be sent by the first network device or by the second network device.

Optionally, the first network device may send the modification indication by using an RRC message, or may carry the modification indication by using a MAC layer message. The modification indication may be information of a mode to be modified, and in this embodiment, information of the modified first mode.

In the foregoing embodiment, the first network device determines that the first mode is modified as an example. Similarly, the first network device may determine to modify the second mode, or the second network device determines to modify the first mode or the second. mode. This application is not limited. In addition, the first network device may be a primary node or a secondary node.

The above is an example of the modification of the first mode. If it is determined to modify the second mode, the second mode may be a modification of the resource location, or may be a modification of the granularity of the time division or the frequency division.

As has been described above, the first mode and the second mode may both be determined by one network device or determined by different network devices. Further, the first mode and the second mode may be terminal specific modes or cell specific modes. The so-called terminal-specific mode is that the transmission mode is independently configured for each terminal; the so-called cell-specific mode is that the transmission mode is independently configured for each cell, and the terminals in the cell are configured with the same transmission mode.

The communication methods in different scenarios are respectively described below with reference to the accompanying drawings.

Please refer to FIG. 7 , which is a schematic diagram of another communication method provided by an embodiment of the present application. In the method, the first mode and the second mode are both determined by the master node, and the first mode and the second mode are terminal specific modes are taken as an example for description. As shown in FIG. 7, the method includes the following steps:

S701: An interface is established between the primary node and the secondary node; or an interface is established between the secondary node and the primary node.

The interface may be referred to as an X2 interface (or an Xn interface) for transmitting information between network devices, for example, for transmitting information between a primary node and a secondary node. The interface establishment process may include: the primary node sends an interface establishment request message to the secondary node; after receiving the interface establishment request, the secondary node sends an interface establishment response message to the primary node.

Optionally, during the interface establishment process, the capability information can be transmitted between the primary node and the secondary node. For example, when the primary node is an LTE network device and the secondary node is an NR network device, the NR secondary node may send capability information to the LTE primary node, where the capability information is used to indicate whether the NR secondary node supports the second mode, that is, whether the LTE spectrum resource sharing is supported. . Further, the LTE master node may also send capability information to the NR secondary node, where the capability information is used to indicate whether the LTE master node supports the second mode, that is, whether the LTE spectrum resource sharing on the NR secondary node is supported; The capability information is not sent to the NR secondary node. By default, when the NR secondary node supports the second mode, the LTE primary node supports the second mode. That is to say, when the NR network device supports the LTE spectrum resource sharing, the LTE network device supports the LTE spectrum resource sharing on the NR network device.

For example, when the secondary node is an LTE network device and the primary node is an NR network device, the NR primary node may send capability information to the LTE secondary node, where the capability information is used to indicate whether the NR primary node supports the second mode, that is, whether the LTE is supported. Spectrum resource sharing. Further, the LTE secondary node may also send capability information to the NR primary node, where the capability information is used to indicate whether the LTE secondary node supports the second mode, that is, whether the LTE spectrum resource sharing on the NR primary node is supported; The capability information is not sent to the NR master node. By default, when the NR master node supports the second mode, the LTE secondary node supports the second mode. That is to say, when the NR network device supports the LTE spectrum resource sharing, the LTE network device supports the LTE spectrum resource sharing on the NR network device.

After the interface between the primary node and the secondary node is established, information can be exchanged between the primary node and the secondary node, for example, the information of the first mode/second mode is exchanged. The above capability information may be transmitted during the interface establishment process. For example, when the primary node sends the capability information to the secondary node, the capability information may be carried in the interface establishment request. When the secondary node sends capability information to the primary node, the capability information may be carried in the interface establishment response. Or you can transfer after the interface is established.

In addition, in addition to transmitting capability information between the primary node and the secondary node, the terminal may also send its own support capability for the second mode to the network side, for example, to the primary node. At this time, the above method further includes the following step S702.

S702: The terminal reports capability information to the primary node, where the capability information is used to indicate the terminal's support capability for the second mode, that is, whether the second mode is supported. In this embodiment, the capability information is used to indicate whether the terminal supports the sharing mode, that is, whether to support spectrum resource sharing, for example, whether to support sending NR information on the LTE spectrum resource.

The step S702 is an optional step, and can replace the capability information that the master node can acquire the terminal from the core network.

In addition, the network side may not acquire the capability information of the terminal, and the default terminal supports the second mode.

In this embodiment and other embodiments of the present application, the support capability of the terminal or the network device for the second mode may be referred to as an uplink sharing capability.

S703: The master node sends a measurement configuration message to the terminal, where the measurement configuration message is used to configure the terminal to measure on the network side.

S704: The terminal performs measurement according to the measurement configuration message, and obtains the measurement result and reports the result to the master node.

The measurement configuration message may include a configuration of the measurement object, for example, configuring a measurement of a frequency point, which may correspond to a cell of the primary node or a cell of the secondary node. The measurement configuration message may also include a configuration for measuring the report, such as a reporting period, or a reporting condition, and the like. The measurement result may include reference signal received power (RSRP) or reference signal received quality (RSRQ). The configuration and reporting of the measurement can be performed by using the existing measurement configuration and reporting mode. The measurement configuration and reporting can also be performed according to the evolution of the technology.

S705: The primary node sends an add request message to the secondary node, where the add request message is used to request to add the secondary node.

The master node may send the information of the first mode and the information of the second mode to the secondary node in the add request message. The description about the information of the first mode and the information of the second mode is the same as the above embodiment. In this embodiment, the first mode is used for LTE spectrum resources and NR spectrum resources are staggered in the time domain for uplink transmission between the terminal and the LTE network device and the NR network device. The second mode is for uplink transmission between the NR network device and the terminal to share LTE spectrum resources. The LTE network device is the primary node, and the NR network device is the secondary node; or the LTE network device is the secondary node, and the NR network device is the primary node.

The information of the first mode is further used to indicate a resource mode of the first mode, and the information of the second mode is further used to indicate a resource mode of the second mode. The description of the resource mode of the first mode and the resource mode of the second mode is the same as the above embodiment. In this embodiment, the resource mode of the first mode is used to indicate the scenario of the first mode, that is, the LTE spectrum resource and the NR spectrum resource are staggered in the time domain for uplink between the terminal and the LTE network device and the NR network device. In the transmission scenario, when the NR network device communicates with the terminal using the NR spectrum resource, the terminal can perform the time domain location of the uplink transmission. The time domain location may be embodied, for example, in the form of a frame, a subframe, a slot, or a symbol. The resource mode of the second mode is used to indicate that in the scenario of the second mode, that is, in the scenario that the uplink transmission between the NR network device and the terminal shares the LTE spectrum resource, the NR network device and the terminal use the LTE spectrum resource for uplink transmission. Resource location. The resource location is, for example, a time domain location, and may be embodied in the form of a frame, a subframe, a slot, or a symbol. Or the resource location may be a frequency domain location, and may be embodied in the form of frequency, bandwidth, and the like. Or the resource location may be a time-frequency location, and may be embodied in the form of a physical resource block (PRB), a PRB pair, or a resource block group (RBG).

In addition, the form of the first mode information transmitted by the master node to the secondary node and the information of the second mode information is the same as the description of the above embodiment. For example, the index of the first mode, the number of the resource mode of the first mode, the index of the second mode, and the number of the resource mode of the second mode.

Optionally, the primary node may also send the measurement result reported by the terminal to the secondary node, and the measurement result sent to the secondary node may be all or part of the measurement result reported by the terminal, and the partial measurement result includes, for example, the cell under the secondary node. Measurement results, such as RSRP, RSRQ, or path loss information. The measurement result sent to the secondary node is referred to as measurement information, and the measurement information may be carried in the addition request message to save the number of messages. Of course, the measurement information can also be sent independently of the add request message.

S706: The secondary node determines the target mode.

The secondary node may select a target mode based on measurement information sent by the primary node. Prior to this, the secondary node may determine the cell serving the terminal based on the measurement information, that is, the serving cell; and determine, according to the measurement information, whether the terminal is located at the center or the edge of the serving cell. For example, when the measurement information includes measurement results of multiple cells, the cell with the best quality of service in the measurement result is selected as the serving cell. Then, it is determined whether the measurement result of the serving cell meets the preset condition. When the preset condition is met, the terminal is located at the center of the serving cell. When the preset condition is not met, the terminal is located at the edge of the serving cell. The preset condition is, for example, an RSRP or RSRQ threshold. When the RSRP or RSRQ in the measurement result is greater than or equal to the threshold, the terminal is located at the center of the serving cell; when the RSRP or RSRQ in the measurement result is less than the threshold value The terminal is located at the edge of the serving cell.

For the terminal located at the cell center, the secondary node may select the NR spectrum resource for uplink transmission, and for the terminal located at the cell edge, the secondary node may select the LTE spectrum resource for uplink transmission. Assuming that the secondary node is an NR network device, the secondary node configures the NR spectrum resource for the uplink transmission or the LTE spectrum resource for the uplink transmission based on the measurement information. If the NR spectrum resource is selected to perform uplink communication with the terminal, the terminal is uplink-scheduled according to the first mode, that is, the terminal is allocated resources for uplink transmission; if the LTE spectrum resource is selected for uplink communication with the terminal, the second is followed. The mode performs uplink scheduling on the terminal, that is, allocates resources for uplink transmission to the terminal.

The secondary node may send the time-frequency resource allocated to the terminal and the information of the target mode to the terminal, so that the terminal may perform pre-processing according to the target mode to perform uplink transmission on the allocated time-frequency resource. At this time, the secondary node generates configuration information, and the configuration information may include information of a target mode, where the information of the target mode is used to indicate a resource mode of the target mode. The terminal receives the configuration information, determines a target resource mode according to the information of the target mode, performs pre-processing based on the target resource mode, and receives uplink scheduling information sent by the network side, and determines time-frequency resources for uplink transmission according to the uplink scheduling information, and The uplink transmission is performed on the time-frequency resource.

Alternatively, the secondary node may send the information of the first mode and the information of the second mode to the terminal, and send the indication information of the selected target mode to the terminal, where the indication information is used to indicate the target mode selected by the secondary node, so that the terminal The target mode is determined according to the information of the target mode, and the information of the target mode may be used only to indicate the target mode without indicating the resource mode. The terminal may determine, according to the indication information of the target mode, that the first mode or the second mode is the target mode, where the information of the first mode and the information of the second mode are used for both the indication mode and the resource mode, so that the target mode may be determined. Resource model. At this time, the secondary node generates configuration information, where the configuration information includes information of the first mode and information of the second mode. The indication information of the target mode may be carried in the configuration information or may be sent separately. The terminal receives the configuration information, and determines a target mode according to the indication information of the target mode. When the target mode is the first mode, determining a resource mode of the first mode according to the information of the first mode, and performing pre-processing to perform uplink by using the resource mode. Transmitting; when the target mode is the second mode, determining a resource mode of the second mode according to the information of the second mode, and performing pre-processing by using the resource mode for uplink transmission. The information of the first mode may include an identifier or an index of the first mode, a number or an index of the resource mode of the first mode; the information of the second mode may include an identifier or an index of the second mode, a number of the resource mode of the second mode, or index. The indication information of the target mode may be an identifier or an index of the target mode, or is 1-bit information. When the information is the first value, the target mode is indicated as the first mode, and when the information is the second value, the target mode is indicated as The second mode.

The indication information of the target mode may be an activation indication. The activation indication is used to instruct the terminal to use the target mode. The time-frequency resource indicated by the uplink scheduling information is an uplink resource, and may include at least one of the following: a physical random access channel (PRACH) resource, a physical uplink shared channel (PUSCH) resource, and a sounding reference. A sounding reference signal (SRS) resource and a physical uplink control channel (PUCCH) resource.

When the secondary node is an NR network device, the configuration information may be an NR RRC message, and the NR RRC message may be sent to the primary node in the form of a container, and the primary node does not parse the container, and is carried in the primary node. The RRC message is sent to the terminal.

For example, the configuration information generated by the secondary node is used as an example. The configuration information may be generated by the primary node and sent to the terminal. The implementation process is the same as the above description, and details are not described herein.

S707: The secondary node sends a response message of adding a request message to the primary node, for example, adding a request acknowledgement message.

The above configuration information may be carried in the add request acknowledgement message and sent to the master node.

Optionally, the secondary node may send the selected communication mode to the primary node, that is, the secondary node notifies the primary node of the target mode. At this time, the secondary node sends the indication information of the target mode to the primary node, where the indication information of the target mode is used to indicate the target mode, for example, the identifier or index of the target mode. For example, the primary node labels the first mode with the identifier 1 and the second mode with the identifier 2. When the secondary node configures the NR spectrum resource for the terminal, the identifier 1 corresponding to the first mode is returned to the primary node. If the secondary node does not inform the primary node of the selected mode, the primary node needs to reserve resources corresponding to the two sets of modes. At this time, resources on the primary node side are wasted. When the secondary node informs the primary node of the target mode, the primary node can reserve only the resources of the target mode, thereby reducing resource waste. Of course, if the primary node selects the target mode, the primary node may notify the secondary node of the selected target mode to reduce resource waste on the secondary node side.

The secondary node may carry the identity or index of the target mode in the add request acknowledgement message. When the above configuration information is sent to the master node in the form of a container, the indication information of the target mode is sent independently of the configuration information, and the configuration information may further include information of the target mode. When the master node can parse the above configuration information, the indication information of the target mode can be sent only in the configuration information.

S708: The master node sends an RRC connection reconfiguration message to the terminal.

The master node receives the add request acknowledgement message sent by the slave node, and resolves the configuration information sent by the slave node, and sends the configuration information to the terminal. For example, the configuration information is an NR RRC configuration message, and the primary node sends the RRC RRC connection configuration message generated by the primary node to the terminal.

In addition, the master node parses out the indication information of the target mode sent by the secondary node, and according to the indication information, the master node can know which part of the uplink resource can be used by itself, to avoid interference with the secondary node.

S709: The terminal sends an RRC connection reconfiguration complete message to the primary node.

After receiving the RRC connection reconfiguration message, the terminal performs the configuration of the primary node and the secondary node respectively. After the configuration is complete, the terminal reverts to the LTE RRC connection reconfiguration complete message. The RRC RRC Connection Reconfiguration Complete message may carry an NR RRC Configuration Complete message.

S710: The primary node sends a secondary node configuration completion message to the secondary node.

The NR RRC configuration complete message generated by the terminal is carried in the secondary node configuration completion message.

Then, the terminal can access the secondary node. The terminal can complete the access between the secondary node and the secondary node according to the configuration of the NR secondary node. If the secondary node is configured with the uplink resource of the NR spectrum, the terminal accesses the NR secondary node in the NR spectrum; if the secondary node configures the uplink resource of the LTE spectrum, the terminal accesses the NR secondary node in the LTE spectrum.

This embodiment is described by taking the master node as an LTE network device and the secondary node as an NR network device as an example. Alternatively, the master node is an NR network device, and the secondary node is an LTE network device, and the master node performs a target mode decision, which is implemented in the same manner as the above embodiment, and details are not described herein. The configuration information generated by the master node may be directly Send to the terminal.

In addition, the decision of the target mode can also be performed by the LTE network device, whether the LTE network device is a primary node or a secondary node.

The information of the first mode and the information of the second mode are transmitted in the configuration flow of initially adding the secondary node, and both transmission modes are determined (or configured) by the primary node. In the following embodiments, both transmission modes are determined (or configured) by the secondary node, and the secondary node provides information of the two transmission modes to the primary node.

The communication method provided by this embodiment includes the respective steps as shown in FIG. Different from the above embodiment, in step S705, the add request message does not carry the information of the first mode and the information of the second mode, but in step S707, the information of the first mode and the second mode are performed by the secondary node. The information is sent to the master node. At this time, the add request message may carry the measurement information.

In addition, the master node may parse the configuration information generated by the secondary node, and when the configuration information includes the information of the first mode and the information of the second mode, the secondary node may use the configuration information to information about the first mode and the information of the second mode. Send to the primary node. If the primary node cannot parse the configuration information generated by the secondary node, the secondary node sends the information of the first mode and the information of the second mode to the primary node independently of the configuration information. In addition, with the above embodiment, the secondary node may also send the indication information of the target mode to the primary node independently of the configuration information.

It can be seen that in the embodiment, both the first mode and the second mode are determined by the secondary node, and the parent node decides which mode to use, that is, determines the target mode. Therefore, the information of the first mode, the information of the second mode, and the indication information of the target mode are carried in the add request acknowledgement message.

In the above embodiment, both transmission modes are determined by one network device (primary node or secondary node). In this embodiment, one transmission mode is determined by the primary node, and the other transmission mode is determined by the secondary node. For example, the master node determines the first mode, the secondary node determines the second mode, or the master node determines the second mode, and the master node determines the first mode. Here, the second mode is determined by the master node, and the master node determines the first mode as an example for description. The communication method of this embodiment includes the respective steps as shown in FIG. Different from the above embodiment, the master node and the secondary node exchange information of the respective determined transmission modes. For example, in step S705, the add request message carries the information of the second mode, and in step S707, the information of the first mode is carried in the request confirmation message. At this time, the add request message may carry the measurement information.

In addition, in the above embodiment, the secondary node may further send the indication information of the target mode to the primary node. The indication information of the target mode may be sent to the primary node independently of the configuration information, and the configuration information may also include the indication information of the target mode.

It can be seen that in the embodiment, the two transmission modes are respectively determined by the primary node and the secondary node, and the secondary node decides which mode to use, that is, determines the target mode.

In the above embodiment, the transmission mode is terminal-specific, and is adapted to transmit information of the mode during the secondary node addition process. If the transmission mode is cell-specific, it is more suitable for transmitting the information of the mode in the interface establishment process (ie, the process shown in step S701 above). For example, the first mode is cell specific and the second mode is terminal specific. If the primary node determines the first mode, the primary node sends the information of the first mode to the secondary node during the interface establishment process, and the information of the first mode may be carried in the interface establishment request message, for example. If the secondary node determines the first mode, the secondary node sends the information of the first mode to the primary node during the interface establishment process, and the information of the first mode may be carried in the interface establishment response message, for example. If the primary node determines the second mode, the primary node sends the information of the second mode to the secondary node in the secondary node adding process, and the information of the second mode may be carried in the secondary node addition request message, for example. If the secondary node determines the second mode, the information of the second mode is sent to the primary node during the secondary node adding process, and the information of the second mode may be carried in the secondary node addition request acknowledgement message, for example. Only the transmission process of the mode information different from the above embodiment is described. For the description of the other processes and the above embodiments, details are not described herein again.

As another example, the first mode and the second mode are both cell specific. If the master node determines the first mode and the second mode, the master node sends the information of the first mode and the second mode to the secondary node during the interface establishment process, where the information of the first mode and the second mode may be carried in, for example, In the interface setup request message. If the secondary node determines the first mode and the second mode, the secondary node sends the information of the first mode and the second mode to the primary node during the interface establishment process, where the information of the first mode and the second mode may be carried in, for example, The interface is built in response to the message. If the primary node determines the first mode, and the secondary node determines the second mode, the primary node sends the information of the first mode to the secondary node during the interface establishment process, where the information of the first mode may be carried in the interface establishment request message, for example. The secondary node sends the information of the second mode to the primary node during the interface establishment process, and the information of the second mode may be carried in the interface establishment response message, for example. If the primary node determines the second mode, the secondary node determines the first mode, and the primary node sends the information of the second mode to the secondary node during the interface establishment process, where the information of the second mode may be carried in the interface establishment request message, for example. The information of the first mode is sent to the master node in the interface establishment process, and the information of the first mode may be carried in the interface setup response message, for example. Only the transmission process of the mode information different from the above embodiment is described. For the description of the other processes and the above embodiments, details are not described herein again.

In the above embodiment, the secondary node decision target mode is described as an example. In addition, the target node may also be determined by the target node, and the indication information of the target mode of the decision may be sent to the secondary node. The implementation is the same as the above description, and will not be described here.

In the above embodiment, the LTE network device is the master node, the NR network device is the secondary node, and the NR secondary node determines the target mode as an example for description. In this embodiment, the NR network device is the master node, and the LTE network device is the secondary node. At this time, the target mode can be determined by the NR master node as an example for description. With the above embodiments, the two transmission modes may be determined by the primary node or the secondary node, or may be determined by the primary node and the secondary node, respectively. And the two transmission modes may be terminal-specific; they may also be cell-specific; or one is terminal-specific and one is cell-specific. The transmission between the primary node and the secondary node in the transmission mode information in different cases is the same as that in the above embodiment, and details are not described herein again.

Please refer to FIG. 8 , which is a schematic diagram of still another communication method according to an embodiment of the present application. As shown in FIG. 8, the method includes the following steps:

S801: An interface is established between the primary node and the secondary node; or an interface is established between the secondary node and the primary node.

S802: The terminal reports capability information to the primary node, where the capability information is used to indicate that the terminal supports the second mode, that is, whether the second mode is supported. In this embodiment, the capability information is used to indicate whether the terminal shares the mode, that is, whether to support spectrum resource sharing, for example, whether to support sending NR information on the LTE spectrum resource.

S803: The master node sends a measurement configuration message to the terminal, where the measurement configuration message is used to configure the terminal to measure on the network side.

S804: The terminal performs measurement according to the measurement configuration message, and reports the measurement result to the primary node.

S805: The primary node sends an add request message to the secondary node, where the add request message is used to request to add the secondary node.

S806: The master node determines the target mode.

S807: The secondary node sends a response message of adding a request message to the primary node, for example, adding a request acknowledgement message.

S808: The master node sends an RRC connection reconfiguration message to the terminal.

S809: The terminal sends an RRC connection reconfiguration complete message to the primary node.

S810: The primary node sends a secondary node configuration completion message to the secondary node.

The difference between this embodiment and the above embodiment is that the target mode is determined by the master node. When both transmission modes are determined by the master node, the master node may determine the target mode before transmitting the add request message (step S805), and carry the information of the target mode in the add request message. That is, step S806 may be before step S805, and thus, the target mode may be notified to the secondary node in the addition request message, thereby saving message overhead. Of course, step S806 can be performed after step S805, or at the same time. If the target mode is to be notified to the secondary node, it is implemented by other messages or new messages. The master node notifies the secondary node of the target mode, and allows the secondary node to reserve the time-frequency resource corresponding to the mode selected by the primary node, and the time-frequency resource corresponding to the unselected mode can be used normally, thereby reducing resource waste.

When both transmission modes are determined by the secondary node, or one of them is determined by the secondary node, after the primary node acquires the transmission mode determined by the secondary node from the secondary node, the above step S806 is performed. For example, the secondary node sends the transmission mode determined by the secondary node to the primary node by adding a request acknowledgement message. Then, the master node determines the target mode based on the measurement information, that is, performs the above step S806.

The master node generates configuration information, and the configuration information is sent to the terminal in the RRC connection reconfiguration message in step S808. The description of the configuration information is the same as the above embodiment, and details are not described herein again.

The secondary node generates an RRC configuration message, and sends the RRC configuration message to the primary node in the add request acknowledgement message. The RRC configuration message may be sent to the master node in the form of a container. The master node generates an RRC connection reconfiguration message, where the RRC connection reconfiguration message includes an RRC configuration message generated by the secondary node and configuration information generated by the master node for the terminal, where the configuration information includes information of the first mode and information of the second mode. Optionally, the indication information of the target mode may also be included.

In the above embodiment, the NR master node decision target mode is taken as an example for description. In addition, the target mode may also be determined by the LTE secondary node, and the indication information of the target mode of the decision may be sent to the primary node. The implementation is the same as the above description, and details are not described herein again.

After the secondary node addition process is completed, the primary node may modify the acknowledged transmission mode, and the secondary node may modify the acknowledged transmission mode. The modification process is the same as the description of the embodiment shown in FIG. 6 above, and details are not described herein again. When the transmission mode is modified, if the primary node determines to modify the target mode, the indication information of the target mode may be sent to the terminal in the RRC connection reconfiguration process shown in FIG. 7 or FIG. 8. If the modified target mode is to modify the transmission mode of the resource mode, the information of the target mode may be sent to the terminal, and the information of the target mode is used to indicate the resource mode of the target mode and the target mode. For example, if the master node determines to modify the resource mode of the first mode, and determines that the modified first mode is the target mode, the information of the target mode may be sent to the terminal. For example, configuration information may be generated, and the configuration information is carried in the RRC connection reconfiguration message of step S708 or S808 and sent to the terminal.

In addition, the target node can modify the target mode, that is, the embodiment shown in FIG. 7 and FIG. 8 can be combined with the embodiment shown in FIG. 7, and details are not described herein again.
