[0099] Both the terminal device and the base station device can perform beamforming, but embodiments of the present application are not limited thereto. In some embodiments, the terminal can perform or not perform beamforming. Also, the base station can perform or not perform beamforming. That is, only one of the terminal and the base station can perform beamforming, or neither of the terminal and the base station can perform beamforming. In the present application, a beam refers to a spatial flow of a signal in a wireless channel, which is formed by one or more antennas or antenna elements, and such a forming process can be referred to as beamforming.

[0100] In addition, the term network side or network device side refers to one side of the network, which can be a certain base station or can include one or more network devices as described above. The term terminal side or terminal device refers to one side of a user or terminal, which can be a certain UE or can include one or more terminal devices as described above.

[0101] Embodiments of the present application provide a data transmission method, which can be applied to the terminal device side as described above, and as shown in Figure 1 The data transmission method can include the following steps in some embodiments of the present application:

[0102] Step 101, negotiating a data bearer control mode with a network device, and obtaining a negotiation result.

[0103] Step 102, matching a target bearer control mode according to the negotiation result and a specified attribute of to-be-transmitted data.

[0104] Step 103, transmitting the to-be-transmitted data according to the target bearer control mode.

[0105] In embodiments of the present application, the terminal device can negotiate a data bearer control mode with the network side. On this basis, the terminal device can match an appropriate data bearer control mode from the negotiation result according to a specified attribute of to-be-transmitted data. In this way, through the way of negotiating the data bearer control mode by both parties, the terminal device can adaptively match an appropriate data bearer control mode, thereby improving the adaptive ability of the terminal device to transmit user data to the network device. In some embodiments of the present application, the data bearer control mode can include supported data bearer control modes (i.e., which data bearer control modes are supported) and allowed switching modes of the data bearer control mode (i.e., which switching between data bearer control modes is supported). The data bearer control mode can include a user plane (UP) and a control plane (CP), etc. The functions of the user plane can include, for example, bearing user data (such as web pages, video streams, VoIP voice, etc.) and directly serving terminal applications. The functions of the control plane can include, for example, transmitting signaling messages, such as connection establishment, authentication, mobility management (such as handover), resource allocation, etc.

[0106] In some embodiments of this application, the negotiation method for the data bearer control method between the terminal device and the network device can be customized. For example, the terminal device and the network device may exchange the data bearer control methods they support, or the network device may inform the terminal device of the data bearer control methods it supports (while the terminal device may choose not to inform the network device of the data bearer control methods it supports).

[0107] Because it is a negotiation, the negotiation result obtained by the terminal device can include data bearer control methods supported by both parties. The terminal device can match a suitable data bearer control method from the negotiation result (i.e., data bearer control methods supported by both parties) according to the specified attributes of the data to be transmitted (i.e., user data to be transmitted). In this way, through this negotiation of data bearer control methods between the two parties, the terminal device can adaptively match a suitable data bearer control method, thereby improving the adaptive ability of the terminal device to transmit user data to the network device.

[0108] In some embodiments of this application, the terminal device can negotiate the data bearer control method with the network device (e.g., the core network on the network side) at a first designated time. This reduces the implementation cost of negotiating the data bearer control method between the terminal and the network side, and avoids the impact on transmission performance caused by incorrect selection of the data bearer control method, thus achieving a balance between transmission efficiency, transmission energy consumption, and transmission performance. In some embodiments of this application, the first designated time includes the registration or attachment process with the network device. By choosing to negotiate the data bearer control method with the network device during the registration or attachment process, negotiation efficiency can be further improved.

[0109] refer to Figure 2 As shown, in some embodiments of this application, negotiating the data bearer control method with the network device at a first specified time may include the following steps:

[0110] Step 201: Send a registration request or an attach request to the network device. The registration request or the attach request includes: first indication information representing the data bearer control mode supported by the terminal.

[0111] In some embodiments of this application, for LTE (4G) application scenarios, since the attach process is a separate process independent of the registration process, the terminal device can negotiate the data bearer control method with the network side during the attach process. In this scenario, the terminal device can send an attach request to the network device, which includes: first indication information representing the data bearer control method supported by the terminal.

[0112] For example, in some embodiments of this application, taking the negotiation of data bearer control mode during the attach process as an example, the first indication information can be carried in the UE network capability field of the attach request. The first indication information can be represented by a corresponding Boolean algebra array, which can further save signaling overhead.

[0113] For example, in an exemplary embodiment of this application, the first instruction information can be defined according to Table 1 as shown below:

[0114] Table 1

[0115]

[0116] Based on Table 1 above, if the terminal device supports user plane data transmission and control plane transmission, and the terminal device supports handover between the control plane and the user plane, then the UE network capability field in the attach request can be supplemented with a field {1,1,1} represented by a Boolean algebra array.

[0117] In other embodiments of this application, for 5G application scenarios, since the attach function is integrated into the registration process, the terminal device can negotiate the data bearer control method with the network side during the registration process with the network device. In this scenario, the terminal device can send a registration request to the core network, which includes: first indication information representing the data bearer control method supported by the terminal.

[0118] Step 202: Receive the registration response or attachment response returned by the network device, wherein the registration response or the attachment response contains: second indication information characterizing the data bearer control mode supported by the network device.

[0119] In some embodiments of this application, in response to an attach request, the network device may return a corresponding attach response (ATTACH ACCEPT); the attach response includes: second indication information characterizing the data bearer control mode supported by the network device.

[0120] For example, in some embodiments of this application, taking the negotiation of data bearer control mode during the attach process as an example, the second indication information may be included in the network feature support field (EPS) in the attach response, where EPS stands for Evolved Packet System. The second indication information may also be represented by a corresponding Boolean algebra array to further save signaling overhead.

[0121] For example, in an exemplary embodiment of this application, the second instruction information can be defined according to Table 2 as shown below:

[0122] Table 2

[0123]

[0124] refer to Figure 3 As shown, in some embodiments of this application, matching the target bearer control method according to the negotiation result and the specified attributes of the data to be transmitted may include the following steps:

[0125] Step 301: Determine the intersection of the data bearer control methods supported by both parties based on the negotiation results.

[0126] In some embodiments of this application, both parties learn about each other's data bearer control methods through negotiation. Therefore, the negotiation result is that both parties know their own data bearer control methods and the other party's data bearer control methods.

[0127] For example, in an exemplary embodiment of this application, if the terminal only supports user plane data transmission and does not support switching between the control plane and the user plane; and the network side supports both user plane data transmission and control plane transmission, and supports switching between the control plane and the user plane; then the intersection of the data bearer control methods supported by both parties is: only user plane data transmission is supported between the terminal and the network side.

[0128] Step 302: Based on the comparison relationship between the specified attributes of the data to be transmitted and the threshold, match the target bearer control method from the intersection of the data bearer control methods.

[0129] In some embodiments of this application, the specified attribute includes a first attribute (e.g., data volume or service rate); the elements in the intersection of the data bearer control methods include the user plane and / or the control plane; the step of matching the target bearer control method from the intersection of the data bearer control methods based on the comparison relationship between the specified attribute of the data to be transmitted and the threshold may include:

[0130] (1) If the first attribute of the data to be transmitted is not less than the first threshold, then the target bearer control mode of the data to be transmitted is selected as the user plane to improve the transmission efficiency.

[0131] (2) If the first attribute of the data to be transmitted is less than the first threshold, the target bearer control mode of the data to be transmitted is selected as the control plane to save transmission overhead.

[0132] In other embodiments of this application, the specified attribute includes a second attribute (e.g., data priority or data sensitivity level); the elements in the intersection of the data bearer control methods include the user plane and / or the control plane; the step of matching the target bearer control method from the intersection of the data bearer control methods based on the comparison relationship between the specified attribute of the data to be transmitted and the threshold includes:

[0133] (1) If the second attribute of the data to be transmitted is not less than the second threshold, the target bearer control mode of the data to be transmitted is selected as the control plane to ensure that, in the case of limited network resources, high-priority data to be transmitted can be transmitted first, or data to be transmitted with high sensitivity level can be transmitted securely.

[0134] (2) If the second attribute of the data to be transmitted is less than the second threshold, then the target bearer control mode of the data to be transmitted is selected as user plane.

[0135] In some embodiments of this application, the first and second thresholds described above can be user-defined, and the user-defined thresholds can be stored as configuration files in the non-volatile memory (NVM) of the terminal device. After the terminal device is powered on, it can read the thresholds from the NVM configuration files and store them in local parameters.

[0136] In some embodiments of this application, transmitting the data to be transmitted according to the target bearer control method means that: after determining the target bearer control method, if the target bearer control method is control plane, the terminal device can initiate a control plane bearer service request (CONTROL PLANE SERVICE REQUEST) to the network device (e.g., a base station on the network side), and carry user data in the user data field of the CONTROL PLANE SERVICE REQUEST signaling, thereby realizing the transmission of user data through the control plane bearer. Similarly, if the target bearer control method is user plane, the terminal device can initiate a service request (SERVICE REQUEST), instructing the network to establish a user plane bearer, and perform data transmission accordingly.

[0137] This application provides another data transmission method, which can be applied to the aforementioned terminal device side, see reference. Figure 4 As shown, in some embodiments of this application, the data transmission method may include the following steps:

[0138] Step 401: Negotiate the data bearer control method with the network device at the first designated time and obtain the negotiation result.

[0139] In some embodiments of this application, the first designated timing includes the registration process with the network device or the attachment process.

[0140] Step 402: Match the target bearer control method according to the negotiation result and the specified attributes of the data to be transmitted.

[0141] Step 403: Transmit the data to be transmitted according to the target bearer control method.

[0142] Step 404: Receive the bearer control mode switching instruction sent by the network device at a second specified time.

[0143] In some embodiments of this application, the network device may send a bearer control mode switching instruction to the network device at a second specified time to instruct the terminal device to perform a bearer mode switching.

[0144] In some embodiments of this application, the network device may send a bearer control mode switching indication to the terminal device at a second specified time via a RadioResourceControlConnectionReconfiguration message. That is, the bearer control mode switching indication (which can be explicit or implicit) is carried in the RRC connection reconfiguration message. For example, in an exemplary embodiment of this application, the bearer control mode switching indication may be carried in an RRCConnectionReconfiguration-NB message.

[0145] In some embodiments of this application, the bearer control mode switching indication can be an indication to release the current Data Radio Bearer (DRB). For example, if the current DRB is a user plane bearer, the terminal device is instructed to release the user plane bearer to switch to a control plane bearer (this example assumes that both the terminal and the network side support both user plane and control plane, and both support switching between user plane and control plane). After the terminal device releases the DRB and replies with RRCConnectionReconfigurationComplete-NB, the terminal device will switch the data transmission from the user plane to the control plane. At this time, the terminal device can continue to transmit user data through uplink / downlink direct transmission messages ULInformationTransfer-NB / DLInformationTransfer-NB.

[0146] In other embodiments of this application, the bearer control mode switching indication may also be an indication to create a new data radio bearer, that is, to instruct the terminal device to create a new data bearer control mode. For example, if the current DRB is a control plane bearer, the terminal device is instructed to create a user plane to switch the data bearer to the user plane (here, we take the example that both the terminal and the network side support both the user plane and the control plane, and both support switching between the user plane and the control plane). After the DRB is established, the terminal device replies with RRCConnectionReconfigurationComplete-NB and switches the data transmission from the control plane to the user plane, and then continues to transmit data through the user plane DRB.

[0147] The second specified timing can be pre-configured. For example, in some embodiments of this application, the second specified timing may include, but is not limited to, changes in the device status of the terminal device or changes in the network load status.

[0148] In some embodiments of this application, a change in device state can refer to the terminal device transitioning from one state to another. For example, in an exemplary embodiment of this application, taking the terminal's battery status as an example, if the terminal device switches from normal mode to energy-saving mode, the network device can instruct the terminal device to switch the data bearer from the user plane to the control plane via a bearer control method switching instruction (here, it is assumed that both the terminal and the network side support both the user plane and the control plane, and both support switching between the user plane and the control plane), in order to save the terminal device's energy consumption. In another exemplary embodiment of this application, taking the terminal's location status as an example, if the terminal device moves from the cell center area to the cell edge area, the network device can instruct the terminal device to switch the data bearer from the user plane to the control plane via a bearer control method switching instruction (here, it is assumed that both the terminal and the network side support both the user plane and the control plane, and both support switching between the user plane and the control plane), in order to ensure the transmission continuity of the terminal device in the cell edge area.

[0149] In some embodiments of this application, a change in network load state can refer to, for example, the network changing from an idle state to a busy state, or from a busy state to an idle state. For example, in an exemplary embodiment of this application, when the network changes from an idle state to a busy state, the network device can instruct the terminal device to switch the data bearer from the user plane to the control plane through a bearer control method switching instruction (here, it is taken as an example that both the terminal and the network side support the user plane and the control plane, and both support switching between the user plane and the control plane), so as to achieve load balancing in scenarios where network resources are limited.

[0150] In some embodiments of this application, when the second specified timing arrives, the network side can determine whether to send a bearer control mode switching indication based on the negotiation result. For example, in an exemplary embodiment of this application, if it is determined based on the negotiation result that the terminal device does not support bearer mode switching, the network side can choose not to send a bearer control mode switching indication to save signaling resources.

[0151] Step 405: Switch the data bearer control mode according to the bearer control mode switching instruction.

[0152] In some embodiments of this application, the terminal device can release the currently established DRB and rebuild a new DRB (different from the currently released DRB) according to the bearer control mode switching instruction.

[0153] Step 406: Continue transmitting the data to be transmitted according to the switched data bearer control mode.

[0154] pass Figure 4 The illustrated embodiment can improve the dynamic adaptive capability of terminal devices when transmitting user data to network devices, and maintain a dynamic balance between transmission efficiency, transmission energy consumption and transmission performance.

[0169] Step 603: Send a bearer control mode switching instruction to the terminal device at the second specified time.

[0177] Step 604: Receive the data to be transmitted by the terminal device according to the switched data bearer control mode.
