Description

[0001] This application is a divisional application of Chinese patent application filed on February 26, 2020, with application number 202010121574.X and title "Data Transmission Method and Apparatus". Technical Field

[0002] This application relates to the field of mobile communication technology, and in particular to a data transmission method and device. Background Technology

[0003] In Long Term Evolution (LTE) systems, when a User Equipment (UE) requires data services, it connects to the wireless network to establish a Radio Resource Control (RRC) connection and a dedicated Data Radio Bearer (DRB) for data transmission. After the UE enters the connected state, the network device allocates necessary configuration parameters for data transmission. Once the UE completes data transmission, it enters the idle state. The network device then releases all configuration parameters of the UE upon entering the idle state. If the UE wishes to re-establish data services, the network device will re-allocate configuration parameters for it.

[0004] In practical applications, some UEs transmit data multiple times within a period of time. For this type of service requirement, if the above transmission mechanism is used, an RRC connection needs to be established for each data transmission, and then released only after the data transmission is completed. When a UE repeatedly transmits data, it inevitably leads to a large amount of signaling interaction, causing excessive signaling load on network equipment and reducing data transmission efficiency. To address this technical issue, in the 5G New Radio (NR) system, after completing data transmission, the UE does not enter an idle state, but rather a new state, namely the inactive state. After entering the inactive state, the UE does not transmit data with the network equipment, but periodically receives paging. Both the network equipment and the UE retain the configuration parameters assigned to the UE. When the UE needs to transmit data, it can quickly enter the connected state using the saved configuration parameters, thereby improving data transmission efficiency.

[0005] In addition to the mechanism of transmitting data after the UE enters the connected state, the NR system introduces two other data transmission mechanisms for UEs in an inactive state: Method 1: The UE carries the data in the MSGA (Message A) sent during the two-step random access process, or the MSG3 sent during the four-step random access process; Method 2: The network device pre-configures transmission resources on the Physical Uplink Shared Channel (PUSCH) for the UE. When the UE is in an idle or inactive state, it can use these resources to transmit data if needed. However, how to rationally select the appropriate data transmission method for a UE in an inactive state when data needs to be transmitted remains to be solved. Summary of the Invention

[0096] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0097] The embodiments of this application can be applied to various communication systems, such as: Advanced Long Term Evolution (LTE-A) systems, New Radio (NR) systems, evolution systems of NR systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), next-generation communication systems, or other communication systems, etc.

[0098] Traditional communication systems typically support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communication but also, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC) communication, and vehicle-to-vehicle (V2V) communication. The embodiments of this application can also be applied to these communication systems.

[0099] Optionally, the communication system in this application embodiment can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) network deployment scenario.

[0100] The embodiments of this application do not limit the spectrum to which the application is applied. For example, the embodiments of this application can be applied to licensed spectrum or unlicensed spectrum.

[0101] Reference Figure 1 , Figure 1 This is a schematic diagram of the architecture of a wireless communication system provided in an embodiment of this application. The wireless communication system provided in this embodiment includes a UE101 and a network device 102.

[0102] Optionally, UE101 can refer to various forms of user equipment, access terminal, user unit, user station, mobile station, mobile station (MS), remote station, remote terminal, mobile device, terminal equipment, wireless communication equipment, user agent, or user device. It can also be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, Wireless Local Loop (WLL) station, PDA, handheld device with wireless communication capabilities, computing device, or other processing device connected to a wireless modem, vehicle-mounted device, wearable device, terminal equipment in future 5G networks, or terminal equipment in future evolved Public Land Mobile Networks (PLMNs), etc. This application embodiment does not limit this, as long as the UE101 can wirelessly communicate with network device 102.

[0103] In this application embodiment, the one-way communication link from the access network to the UE is defined as the downlink, the data transmitted on the downlink is called downlink data, and the transmission direction of the downlink data is called the downlink direction; while the one-way communication link from the UE to the access network is defined as the uplink, the data transmitted on the uplink is called uplink data, and the transmission direction of the uplink data is called the uplink direction.

[0104] Optionally, network device 102, also known as public mobile communication network device, is the interface device for UE101 to access the Internet. It is also a form of radio station, which refers to a radio transceiver station that transmits information with UE101 within a certain radio coverage area. It includes base stations (BS), also known as base station equipment, which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in 2G networks, devices providing base station functionality include Base Transceiver Stations (BTS); in 3G networks, NodeBs; in 4G networks, evolved NodeBs (eNBs); in Wireless Local Area Networks (WLANs), access points (APs) provide base station functionality; in 5G NR, gNBs provide base station functionality, and further evolved NodeBs (ng-eNBs) provide base station functionality. The gNB and UE communicate using NR technology, while the ng-eNB and UE communicate using Evolved Universal Terrestrial Radio Access (E-UTRA) technology. Both gNBs and ng-eNBs can connect to the 5G core network. The network device 102 in this embodiment also includes devices providing base station functionality in future new communication systems.

[0105] In one feasible implementation, the network device can send uplink scheduling information (UL Grant) to the UE via downlink control information (DCI) to instruct the uplink physical shared channel (PUSCH) to transmit data so that the UE can send data.

[0106] Optionally, the UL grant may include the following information:

[0107] Resource allocation information (Resource block assignment and hopping resource allocation);

[0108] Modulation and coding scheme and redundancy version information: used to specify the modulation and coding scheme (MCS), redundancy version (RV) of the corresponding PUSCH transmission, and to determine the transport block size (TBsize).

[0109] New data indicator: Used to determine whether the current transmission is a new transmission or a retransmission;

[0110] TPC commands for scheduling PUSCH: used for PUSCH power control;

[0111] HARQ process number: Used to specify the HARQ process corresponding to the current transfer.

[0112] In addition, for uplink transmission, there are generally two types of pre-configured / semi-static resource configuration methods:

[0113] Pre-configuration (pre-authorization) method 1: Configuration via Radio Resource Control (RRC) layer signaling (IE Configured Grant Config).

[0114] Pre-configuration (pre-authorization) method 2: The DCI instructs the activation and deactivation of uplink pre-configured / semi-static resources. Some of the configuration parameters required are configured in advance by the network device through RRC signaling in IE Configured GrantConfig, but they need to be activated by the DCI before they can be used.

[0115] Optionally, the embodiments of this application can be applied to various periodic services. The network device can use semi-static scheduling (SPS) or pre-configured grant (CG) to configure periodic transmission resources for the UE.

[0116] Optionally, the embodiments of this application can also be applied to non-periodic services.

[0117] In communication systems that incorporate carrier aggregation, the carriers used for aggregation are called component carriers (CCs), also known as serving cells. These include primary component carriers / cells (PCCs / PCells) and secondary component carriers / cells (SCCs / SCells). A communication system with carrier aggregation must contain at least one primary serving cell and one secondary serving cell, with the primary serving cell always active.

[0118] In this embodiment of the application, when the UE is in an idle or inactive state, if it needs to initiate data transmission, it needs to perform a random access procedure to transition to a connected state. For details, please refer to... Figure 2 , Figure 2 This application provides a signaling illustration of state transition in the data transmission method provided in the embodiments of this application. Figure 1 In this embodiment of the application, the process of the UE transitioning from an idle state or an inactive state to a connected state includes:

[0119] Step 1: The UE selects an SSB or CSI-RS from the eligible Synchronization Signal (SS) / Physical Broadcast Channel (PBCH) resource blocks (SSBs) or Channel State Information Reference Signals (CSI-RS), and then selects a preamble sequence to send the random access preamble sequence, Msg1, on the allowed time-frequency resources.

[0120] Step 2: The UE receives the random access response sent by the network device, namely Msg2: Random AccessResponse, which contains TA information (Timing Advance).

[0121] Step 3: The UE uses the authorization received in Msg2 to send the scheduled transmission information, namely Msg3: ScheduledTransmission.

[0122] Step 4: If the UE receives the conflict resolution information, namely Msg4: Contention Resolution, it considers the conflict resolution successful and the random access process successful. If it does not receive scheduling from the base station within a certain period of time, it considers the conflict resolution to have failed.

[0123] To accelerate the random access process, reduce latency, and decrease the number of messages, a two-step random access process is proposed. For details, please refer to [link / reference needed]. Figure 3 , Figure 3 This application provides a signaling illustration of state transition in the data transmission method provided in the embodiments of this application. Figure 2 .

[0124] Figure 3 In MsgA, MsgA contains the original Msg1 and Msg3 information, namely the preamble sent on the Physical Random Access Channel (PRACH) and the payload sent on the Physical Uplink Shared Channel (PUSCH); MsgB contains Msg2 and Msg4 information.

[0125] In this embodiment of the application, in order to send data in a disconnected state, the data to be transmitted can be sent in addition to the RRC message in Msg3 or MsgA; or the UE’s data to be transmitted and the UE’s identification information can be sent only in MSG3 or MSGA.

[0126] For a UE in an idle or inactive state, if data to be transmitted is generated in the UE, there are three possible data transmission methods: Method 1: The UE transmits the data in the MSGA sent by the UE during the two-step random access process, or the MSG3 sent by the UE during the four-step random access process; Method 2: The UE transmits data based on the transmission resources pre-configured by the network device; Method 3: The UE transmits data after migrating to the connected state. However, there is currently a lack of a solution that can reasonably select the appropriate data transmission method.

[0127] To address the aforementioned technical problems, this application provides a data transmission method. When the UE is in an idle or inactive state, if data to be transmitted is generated in the UE, the number of bits of the data to be transmitted in the UE is determined. Then, the target transmission method corresponding to the number of bits in the transmission configuration information is determined, and the data to be transmitted is transmitted according to the target transmission method. Since the amount of data transmitted during random access is generally small, and the amount of data transmitted based on the transmission resources pre-configured by the network device depends on the size of the pre-configured resources, while the amount of data transmitted after the UE migrates to the connected state is usually unlimited, when the UE is in an idle or inactive state and has data to be transmitted, the number of bits of the data to be transmitted can help the UE select a suitable data transmission method.

[0128] Based on the above theory, this application proposes a data transmission method, referring to... Figure 4 , Figure 4 This is a flowchart illustrating the data transmission method provided in the embodiments of this application. Figure 1 The execution subject of this embodiment is Figure 1 The UE in the illustrated embodiment. Figure 4 As shown, the method includes:

[0129] S401. Determine the number of bits of data to be transmitted in the UE.

[0130] In this embodiment, before the UE enters the idle or inactive state, the network device can pre-configure transmission resources (PUR) on the PUSCH for the UE. When the UE is in the idle or inactive state, if data to be transmitted is detected in the UE, the number of bits of data to be transmitted in the UE is determined. The UE's determination of the number of bits to be transmitted is an implementation of the UE and can be implemented in different ways, such as the UE determining the data submitted by the application layer to the access layer for transmission, and the UE's access layer determining the number of bits of data to be transmitted.

[0131] S402. Determine the target transmission method corresponding to the above number of bits in the transmission configuration information. The target transmission method includes any one of the following: the UE transmits data based on a random access procedure, the UE transmits data based on transmission resources pre-configured by the network device, or the UE transmits data after migrating to the connected state.

[0132] In this embodiment of the application, the UE can determine the above-mentioned transmission configuration information based on its own configured data transmission mechanism or from the indication information sent by the network device. The transmission configuration information includes the transmission mode corresponding to the number of bits in each value range.

[0133] Once the UE determines the number of bits of the data to be transmitted, it can determine the target transmission method corresponding to the number of bits of the data to be transmitted based on the aforementioned transmission configuration information.

[0134] For example, assuming the number of bits in the above transmission configuration information is less than 200 bits, the UE performs data transmission based on the random access procedure; when the number of bits is greater than or equal to 200 bits and less than 1000 bits, the UE performs data transmission based on the transmission resources pre-configured by the network device; when the number of bits is greater than or equal to 1000 bits, the UE performs data transmission after transitioning to the connected state. Therefore, if the UE determines that the number of bits of data to be transmitted is 800 bits, it can determine that the target transmission method is data transmission based on the transmission resources pre-configured by the network device.

[0135] S403. Transmit the data to be transmitted according to the target transmission method.

[0136] In this embodiment, when the target transmission method is data transmission by the UE based on a random access procedure, the UE can carry the data to be transmitted in the MSGA sent by the UE in a two-step random access procedure or the MSG3 sent by the UE in a four-step random access procedure and send it to the network device; when the target transmission method is data transmission by the UE based on the transmission resources pre-configured by the network device, the UE carries the data to be transmitted on the pre-configured transmission resources and sends it to the network device; when the target transmission method is data transmission after the UE has migrated to the connected state, the UE first migrates from the idle state or the inactive state to the connected state, and then sends the data to be transmitted to the network device through the established connection.

[0137] The data transmission method provided in this application, when the UE is in an idle or inactive state, if data to be transmitted is generated in the UE, determines the number of bits of the data to be transmitted in the UE; then, it determines the target transmission method corresponding to the number of bits in the transmission configuration information, and transmits the data to be transmitted according to the target transmission method. The target transmission method includes any one of the following: the UE transmits data based on a random access procedure, the UE transmits data based on transmission resources pre-configured by the network device, and the UE transmits data after migrating to a connected state. The amount of data that can be transmitted through a random access procedure is generally relatively small, the amount of data transmitted based on transmission resources pre-configured by the network device depends on the size of the pre-configured resources, and the amount of data transmitted after the UE migrates to a connected state is usually unlimited. That is, the above-mentioned target transmission methods are suitable for transmitting data with different bit counts. Therefore, when the UE is in an idle or inactive state and has data to be transmitted, the number of bits of the data to be transmitted helps the UE select a suitable data transmission method, improving data transmission efficiency.

[0138] Based on the content described in the above embodiments, referring to Figure 5 , Figure 5 This is a flowchart illustrating the data transmission method provided in the embodiments of this application. Figure 2 The execution subject of this embodiment is Figure 1 The UE in the illustrated embodiment. Figure 5 As shown, the method includes:

[0139] S501. Obtain the transmission configuration information from the network device.

[0140] In one feasible implementation, the UE receives a Radio Resource Control (RRC) release message from the network device, the RRC release message including the aforementioned transmission configuration information.

[0141] Optionally, the network may use an RRC release message to migrate the UE to an idle or inactive state. The aforementioned transmission configuration information can be configured in this RRC release message, and the transmission configuration information can be different for each UE.

[0142] In another feasible implementation, the UE receives a System Information Block (SIB) from the network device, which includes the aforementioned transmission configuration information.

[0143] Optionally, idle or inactive UEs may select or reselect a cell based on cell measurement reselection parameters and camp on a cell. When a cell is reselected to a new cell, the UE needs to read the SIB to obtain the relevant information of the cell, where the SIB contains the aforementioned transmission configuration information.

[0144] S502. Determine the number of bits of data to be transmitted in the UE.

[0145] S503. Based on the transmission configuration information, determine the target transmission mode corresponding to the above number of bits. The target transmission mode includes any one of the following modes: the UE transmits data based on a random access procedure, the UE transmits data based on transmission resources pre-configured by the network device, or the UE transmits data after migrating to the connected state.

[0146] S504. Transmit the data to be transmitted according to the target transmission method.

[0147] In this embodiment, after the UE obtains transmission configuration information from the network device, when the UE is in an idle or inactive state and has data to be transmitted, it can determine the target transmission method corresponding to the number of bits of the data to be transmitted based on the transmission configuration information, and transmit the data to be transmitted according to the target transmission method. The network device can flexibly configure the aforementioned transmission configuration information according to data transmission requirements, thereby enabling the UE to select a reasonable data transmission method for data transmission.

[0148] Based on the content described in the above embodiments, referring to Figure 6 , Figure 6 This is a flowchart illustrating a data transmission method provided in an embodiment of this application. Figure 3 .

[0149] When the UE is in an idle or inactive state, if data that needs to be transmitted is detected to be generated in the UE, the above data transmission method includes:

[0150] S601. Determine the number of bits of data to be transmitted in the UE.

[0151] S602. Determine whether the pre-configured transmission resources meet the preset transmission conditions. If the pre-configured transmission resources meet the preset transmission conditions, execute steps S603 to S604; otherwise, execute step S605.

[0152] Steps S601 and S602 can be implemented in parallel.

[0153] Optionally, the above-mentioned preset transmission conditions are any one or more of the following transmission conditions:

[0154] First, the pre-configured transmission resources are associated with the services corresponding to the data to be transmitted.

[0155] Understandably, the services provided by a UE will differ depending on the application it is running. After establishing an RRC connection and completing authentication upon accessing the network, the UE can establish one or more Data Radio Bearers (DRBs) according to service requirements. For each DRB, the UE can report the characteristics of each service via UE Auxiliary Information Messages, such as the data packet generation period, the data packet generation time offset (start time within a period), and the data packet size. This allows the network device to pre-configure the transmission resources corresponding to each DRB for the UE, or to pre-configure multiple DRBs corresponding to one transmission resource for the UE. It is worth noting that the network device can pre-configure the corresponding transmission resources according to the logical channel carrying the DRB.

[0156] If the pre-configured transmission resources are inconsistent with the pre-configured transmission resources of the DRB corresponding to the data to be transmitted, it can be considered that the pre-configured transmission resources are not associated with the service corresponding to the data to be transmitted. In this case, the UE cannot transmit the data to be transmitted based on the pre-configured transmission resources.

[0157] Optionally, when the pre-configured transmission resources are not associated with the service corresponding to the data to be transmitted, the UE can choose to migrate to the connected state before transmitting the data to be transmitted.

[0158] Second, the time interval between the start time of the pre-configured transmission resources and the generation time of the data to be transmitted is less than the preset time.

[0159] It is understandable that when the UE generates data to be transmitted, if the time interval between the generation time of the data to be transmitted and the time domain start time of the pre-configured transmission resource is long, the UE will need to wait a long time before transmitting the data to be transmitted if it still uses the transmission resource. This will inevitably lead to a large delay in data transmission and affect the user experience.

[0160] Optionally, when the time interval between the start time of the pre-configured transmission resources and the generation time of the data to be transmitted is greater than or equal to a preset time, the UE may choose to migrate to the connected state before transmitting the aforementioned data to be transmitted.

[0161] Third, the serving cell corresponding to the pre-configured transmission resources is the serving cell where the UE is currently camped.

[0162] It is understandable that since the UE can only use the transmission resource to send data when it is camped in the serving cell corresponding to the pre-configured transmission resource, the UE cannot transmit the data to be transmitted based on the pre-configured transmission resource when the serving cell currently camped by the UE is different from the serving cell corresponding to the pre-configured transmission resource.

[0163] Optionally, when the serving cell where the UE is currently camped is different from the serving cell corresponding to the pre-configured transmission resources, the UE can choose to migrate to the connected state before transmitting the data to be transmitted.

[0164] Fourth, the serving cell corresponding to the pre-configured transmission resources is the serving cell where the UE is currently camped, and the UE measures that the signal quality of one or more beams corresponding to the pre-configured transmission resources of the network device exceeds a preset threshold.

[0165] When configuring transmission resources, network devices can configure one or more beams corresponding to those transmission resources. A serving cell can have one or more beams; for example, a cell can have multiple SSBs, each represented by a different SSB index. When a UE is in the serving cell, it can receive signals from one or more SSBs. Network devices typically do not apply pre-configured transmission resources to all SSBs, as this would consume too many radio resources. Network devices can pre-configure transmission resources corresponding to one or more SSBs. Only when the UE measures that the signal quality of these one or more SSBs exceeds a preset threshold can the pre-configured transmission resources be applied for uplink data transmission.

[0166] 5. The UE's moving speed is lower than the preset speed threshold.

[0167] If the UE can determine its own speed, when the UE is moving very fast, the pre-configured transmission resources cannot adapt well to the rapid changes in the radio link, and therefore are not suitable for transmitting uplink data. Pre-configured transmission resources can only be applied when the UE's speed is below a preset speed threshold.

[0168] Additionally, if the network device is configured with Timing Advance (TA), then when TA is active, steps S603 to S604 are executed; otherwise, step S605 is executed.

[0169] S603. Based on the transmission configuration information, determine the target transmission mode corresponding to the number of bits. The target transmission mode includes any one of the following: the UE transmits data based on a random access procedure, the UE transmits data based on transmission resources pre-configured by the network device, or the UE transmits data after migrating to the connected state.

[0170] S604. Transmit the data to be transmitted according to the target transmission method.

[0171] S605. Data transmission is performed after the UE migrates to the connected state.

[0172] In this embodiment of the application, when the UE is in an idle state or an inactive state, if data to be sent is detected in the UE, the UE first determines whether the pre-configured transmission resources meet the preset transmission conditions. If they do, the UE determines the target transmission method corresponding to the number of bits of the data to be transmitted in the UE and according to the transmission configuration information. If they do not meet the conditions, it means that the UE cannot currently use the pre-configured transmission resources, and then migrates to the connected state to transmit data, thereby ensuring the reliability of data transmission.

[0173] Based on the content described in the above embodiments, in one feasible implementation of this application, the transmission configuration information includes a first threshold and a second threshold, as well as transmission selection methods corresponding to the first and second thresholds. The first threshold is less than the second threshold; the transmission selection methods corresponding to the first and second thresholds include:

[0174] Method a: When the target number of bits is less than the first threshold, the UE selects to transmit data based on the random access procedure.

[0175] Method b: When the target number of bits is greater than or equal to the first threshold and less than the second threshold, the UE selects to transmit data based on the transmission resources pre-configured by the network device.

[0176] Method c: When the target number of bits is greater than or equal to the second threshold, the UE chooses to migrate to the connected state before transmitting data.

[0177] Reference Figure 7 , Figure 7 This is a flowchart illustrating a data transmission method provided in an embodiment of this application. Figure 4 In this embodiment, when the UE is in an idle or inactive state, if data to be transmitted is detected to be generated in the UE, the above data transmission method includes:

[0178] S701. Determine the number of bits of data to be transmitted in the UE.

[0179] S702. Determine whether the pre-configured transmission resources meet the preset transmission conditions. If the pre-configured transmission resources meet the preset transmission conditions, execute steps S703 to S706; otherwise, execute step S707.

[0180] Steps S701 and S702 can be performed in parallel.

[0181] S703. When the number of bits mentioned above is less than the first threshold, the target transmission mode is determined to be data transmission by the UE based on the random access procedure.

[0182] S704. When the number of bits mentioned above is greater than or equal to the first threshold and less than the second threshold, the target transmission mode is determined to be data transmission by the UE based on the transmission resources pre-configured by the network device.

[0183] S705. When the number of bits mentioned above is greater than or equal to the second threshold, the target transmission mode is determined to be data transmission after the UE migrates to the connected state.

[0184] S706. Transmit the data to be transmitted according to the target transmission method.

[0185] S707: Data transmission is performed after the UE migrates to the connected state.

[0186] Understandably, when the number of bits of data to be transmitted is small, if the UE chooses to transmit data based on the transmission resources pre-configured by the network device, the small amount of data transmission causes the UE to occupy the entire pre-configured transmission resources. Since the pre-configured transmission resources can be shared by multiple UEs, a small amount of data occupying the entire pre-configured transmission resources will cause data transmission failures for other UEs, thereby affecting the spectrum efficiency of the entire communication system.

[0187] However, when the number of bits of data to be transmitted is large, exceeding the maximum amount of data that the pre-configured transmission resources can transmit, data transmission may fail, affecting the reliability of data transmission.

[0188] In this embodiment, the network device can reasonably configure the aforementioned transmission configuration information based on the size of the transmission resources configured for the UE. When the number of bits of data to be transmitted is small, the UE chooses to transmit data based on a random access procedure, which can avoid the UE occupying the entire pre-configured transmission resources due to a small amount of data transmission. When the number of bits of data to be transmitted is large, the UE chooses to migrate to the connected state before transmitting data, thereby ensuring the reliability of data transmission.

[0189] In this embodiment, if the pre-configured transmission resources meet the preset transmission conditions, it can be determined whether the number of bits of the data to be transmitted is less than a first threshold. If it is less than the first threshold, the target transmission mode is determined to be data transmission by the UE based on a random access procedure; if it is greater than or equal to the first threshold, data transmission is performed after migrating to the connected state. The process of the UE migrating to the connected state is an existing implementation and will not be described in detail here.

[0190] Based on the content described in the above embodiments, in another feasible embodiment of this application, the transmission configuration information includes a first threshold and a transmission selection method corresponding to the first threshold; wherein, the transmission selection method corresponding to the first threshold includes:

[0191] Method d: When the target number of bits is less than the first threshold, the UE selects to transmit data based on the random access procedure.

[0192] Method e: When the target number of bits is greater than or equal to the first threshold, the UE selects to transmit data based on the transmission resources pre-configured by the network device.

[0195] S802. Determine whether the pre-configured transmission resources meet the preset transmission conditions. If the pre-configured transmission resources meet the preset transmission conditions, execute steps S803 to S805; otherwise, execute step S806.

[0199] S805. Transmit the data to be transmitted according to the target transmission method.

[0200] S806. Data transmission is performed after the UE migrates to the connected state.

[0201] In this embodiment of the application, when the maximum amount of data that can be transmitted by the transmission resources pre-configured by the network device for the UE can meet the maximum demand of the UE's current service to be transmitted, the UE can choose to transmit data based on the random access procedure when the target number of bits is less than the first threshold; when the target number of bits is greater than or equal to the first threshold, the UE can choose to transmit data based on the transmission resources pre-configured by the network device, thereby avoiding the UE occupying the entire pre-configured transmission resources due to a small amount of data transmission.

[0202] Based on the content described in the above embodiments, in another feasible implementation of this application, the transmission configuration information includes a second threshold and a transmission selection method corresponding to the second threshold; wherein, the transmission selection method corresponding to the second threshold includes:

[0203] Method g: When the target number of bits is less than the second threshold, the UE selects to transmit data based on the transmission resources pre-configured by the network device.

[0204] Method h: When the target number of bits is greater than or equal to the second threshold, the UE chooses to migrate to the connected state before transmitting data.

[0206] S901. Determine the number of bits of data to be transmitted in the UE.

[0207] S902. Determine whether the pre-configured transmission resources meet the preset transmission conditions. If the pre-configured transmission resources meet the preset transmission conditions, execute steps S903 to S905; otherwise, execute step S906.

[0208] Optionally, steps S901 and S902 can be implemented in parallel.

[0209] S903. When the number of bits mentioned above is less than the second threshold, the target transmission mode is determined to be that the UE transmits data based on the transmission resources pre-configured by the network device.

[0210] S904. When the number of bits mentioned above is greater than or equal to the second threshold, the target transmission mode is determined to be data transmission after the UE migrates to the connected state.

[0211] S905. Transmit the data to be transmitted according to the target transmission method.

[0212] S906. Data transmission is performed after the UE migrates to the connected state.

[0213] It is understandable that when the number of bits of data to be transmitted is large, exceeding the maximum amount of data that the pre-configured transmission resources can transmit, data transmission may fail, affecting the reliability of data transmission.

[0214] In this embodiment, the network device can reasonably configure the above transmission configuration information based on the size of the transmission resources configured for the UE. When the number of bits of the data to be transmitted is large, the UE can choose to migrate to the connected state before transmitting the data, thereby ensuring the reliability of data transmission.
