图1是根据一示例性实施例示出的一种实施环境的示意图。该实施环境中主要包括用户设备(User Equipment，UE)110和基站120。该用户设备110可以通过通信网络与该基站120之间进行通信，该用户设备110可以根据本申请实施例提供的方法进行数据传输，该用户设备110为一切能够实现数据传输的设备，在一些实施例中，该用户设备110又可以称为终端；基站可以为演进型基站(evolved Node B，eNB)，也即***移动通信技术(the 4th Generation mobile communication technology，4G)基站；或者5g基站(5th-generation Node B，gNB)，本申请实施例对此不做限定。Fig. 1 is a schematic diagram showing an implementation environment according to an exemplary embodiment. The implementation environment mainly includes a user equipment (User Equipment, UE) 110 and a base station 120. The user equipment 110 can communicate with the base station 120 through a communication network. The user equipment 110 can perform data transmission according to the method provided in the embodiments of the present application. The user equipment 110 is any device capable of data transmission. In some implementations, In an example, the user equipment 110 may also be called a terminal; the base station may be an evolved Node B (eNB), that is, the 4th Generation mobile communication technology (4G) base station; or a 5g base station (5th-generation Node B, gNB), which is not limited in this embodiment of the application.

在本申请实施例中，基站120为用户设备110分配的资源为D-PUR；用户设备110通过该D-PUR向基站120传输目标数据。In this embodiment of the present application, the resource allocated by the base station 120 to the user equipment 110 is D-PUR; the user equipment 110 transmits target data to the base station 120 through the D-PUR.

其中，用户设备110可以为物联网***中的任一用户设备，也可以为物联网***中业务类型单一的用户设备。例如，用户设备110可以为智能水表、智能电表、智能燃气表、温度控制器、湿度控制器等用户设备。在长期演进(Long Term Evolution，LTE)***中，已经引入了小数据传输(Early Data Transmission，EDT)。小数据传输是指用户设备110在空闲状态(idle)、挂起状态(suspend)或者非激活状态(inactive)下进行的上行和/或下行小数据的传输。The user equipment 110 may be any user equipment in the Internet of Things system, or may be a user equipment with a single service type in the Internet of Things system. For example, the user equipment 110 may be user equipment such as a smart water meter, a smart electric meter, a smart gas meter, a temperature controller, and a humidity controller. In the Long Term Evolution (LTE) system, small data transmission (Early Data Transmission, EDT) has been introduced.

其中，小数据可以为数据量较小的数据，也即小数据为数据量小于预设数据量的数据。例如，用户设备110为温度控制器，相应的，小数据可以为温度控制器探测到的温度变化数据。小数据还可以是指定业务类型对应的数据。指定业务类型可以是非即时性业务类型。预设数据量可以根据需要进行设置并更改；在本申请实施例中，对预设数据量不作具体限定；例如，预设数据量可以为5比特或者5兆等。用户设备110通过D-PUR向基站120传输的目标数据可以为上述的小数据。Among them, small data may be data with a small amount of data, that is, small data is data with a data amount less than a preset data amount. For example, the user equipment 110 is a temperature controller, and correspondingly, the small data may be temperature change data detected by the temperature controller. Small data can also be data corresponding to a specified service type. The designated service type may be a non-immediate service type. The preset data amount can be set and changed as needed; in the embodiment of the present application, the preset data amount is not specifically limited; for example, the preset data amount may be 5 bits or 5 megabytes, etc. The target data transmitted by the user equipment 110 to the base station 120 through D-PUR may be the aforementioned small data.

图2是根据一示例性实施例示出的一种数据传输方法的流程图，该方法可以应用于上述实施环境中的用户设备，该方法可以包括如下几个实现步骤：Fig. 2 is a flow chart showing a data transmission method according to an exemplary embodiment. The method can be applied to user equipment in the foregoing implementation environment. The method can include the following implementation steps:

步骤201：用户设备通过第一D-PUR向基站传输目标数据。Step 201: The user equipment transmits target data to the base station through the first D-PUR.

在5G网络中，用户设备可以在任一状态下通过第一D-PUR向基站传输目标数据；用户设备也可以在某些特定状态下，通过第一D-PUR向基站传输目标数据。特定状态可以为空闲状态(idle)、挂起状态(suspend)或者非激活状态(inactive)。相应的，本步骤可以为：当用户设备处于idle、suspend或者inactive的情况下，通过第一D-PUR向基站传输目标数据。In a 5G network, the user equipment may transmit target data to the base station through the first D-PUR in any state; the user equipment may also transmit target data to the base station through the first D-PUR in certain specific states. The specific state can be an idle state (idle), a suspended state (suspend) or an inactive state (inactive). Correspondingly, this step may be: when the user equipment is in idle, suspend or inactive, the target data is transmitted to the base station through the first D-PUR.

当用户设备处于idle、suspend或者inactive的情况下，基站会为用户设备配置至少一个D-PUR，用户设备可以通过至少一个D-PUR中的第一D-PUR向基站传输目标数据。其中，基站可以周期性的为用户设备配置D-PUR，也可以在用户设备首次接入基站时为用户设备配置D-PUR，也可以在用户设备需要传输目标数据时为用户设备配置D-PUR。在本申请实施例中，对基站为用户设备配置D-PUR的实际方式不作具体限定。并且，基站为用户设备配置D-PUR时，还配置了该D-PUR的持续时间，以及该D-PUR的TB size(Transport Block size，传输块大小)。例如，基站可以每1小时为用户设备配置一次D-PUR，该D-PUR的持续时间可以为1分钟或1小时等，该D-PUR的TB size为能够在该D-PUR上传输的最大数据量。When the user equipment is idle, suspended or inactive, the base station will configure at least one D-PUR for the user equipment, and the user equipment may transmit target data to the base station through the first D-PUR of the at least one D-PUR. Among them, the base station can periodically configure D-PUR for the user equipment, or configure D-PUR for the user equipment when the user equipment accesses the base station for the first time, or configure D-PUR for the user equipment when the user equipment needs to transmit target data. . In the embodiments of the present application, the actual manner in which the base station configures D-PUR for the user equipment is not specifically limited. In addition, when the base station configures the D-PUR for the user equipment, it also configures the duration of the D-PUR and the TB size (Transport Block size) of the D-PUR. For example, the base station can configure D-PUR for the user equipment once every 1 hour, the duration of the D-PUR can be 1 minute or 1 hour, etc. The TB size of the D-PUR is the maximum that can be transmitted on the D-PUR The amount of data.

在本申请实施例中，基站可以每次为用户设备配置一个D-PUR，也可以每次为用户设备配置多个D-PUR。在本申请实施例中，对基站为用户设备配置D-PUR的多少不作具体限定。在一种可能的实现方式中，基站可以根据用户设备的设备类型，为该用户设备配置与该设备类型匹配的至少一个D-PUR。例如，用户设备为智能电表类型；则基站为智能电表配置10个D-PUR；用户设备为控制器，则基站为控制器配置8个D-PUR。在另一种可能的实现方式中，基站还可以根据目标数据的业务类型，为该用户设备配置与该业务类型匹配的至少一个D-PUR。在另一种可能的实现方式中，基站还可以根据该用户设备传输的目标数据的数据量，为该用户设备配置与该数据量匹配的至少一个D-PUR。In the embodiment of the present application, the base station may configure one D-PUR for the user equipment at a time, or may configure multiple D-PURs for the user equipment at a time. In the embodiment of the present application, the number of D-PUR configured by the base station for the user equipment is not specifically limited. In a possible implementation manner, the base station may configure the user equipment with at least one D-PUR matching the equipment type according to the equipment type of the user equipment. For example, if the user equipment is a smart meter type; then the base station configures 10 D-PURs for the smart meter; if the user equipment is a controller, the base station configures 8 D-PURs for the controller. In another possible implementation manner, the base station may also configure at least one D-PUR matching the service type for the user equipment according to the service type of the target data. In another possible implementation manner, the base station may also configure the user equipment with at least one D-PUR matching the data volume according to the data volume of the target data transmitted by the user equipment.

当用户设备处于idle、suspend或者inactive的情况下，向基站传输目标数据之前，用户设备从基站配置的至少一个D-PUR中选择一个D-PUR，为了便于与后续进行重传的D-PUR进行区分，将这次选择的D-PUR称为第一D-PUR。其中，用户设备从基站配置的至少一个D-PUR中选择一个D-PUR的步骤可以为：用户设备可以从基站配置的至少一个D-PUR中随机选择一个D-PUR；也可以从基站配置的至少一个D-PUR中选择一个离上一个被使用的D-PUR最近的D-PUR。When the user equipment is idle, suspend or inactive, before transmitting target data to the base station, the user equipment selects a D-PUR from at least one D-PUR configured by the base station, in order to facilitate the subsequent retransmission of the D-PUR To distinguish, the D-PUR selected this time is called the first D-PUR. The step of the user equipment selecting one D-PUR from the at least one D-PUR configured by the base station may be: the user equipment may randomly select a D-PUR from the at least one D-PUR configured by the base station; it may also be configured from the base station. Select one of the at least one D-PUR that is closest to the last used D-PUR.

用户设备选择出第一D-PUR之后，用户设备通过第一D-PUR，向基站传输目标数据。并且，目标数据可以为控制面(Control Plane，CP)方案中的数据，也可以为用户面(User Plane， UP)方案中的数据。当目标数据为控制面方案中的数据时，参见图3，用户设备向基站传输目标数据的过程可以通过以下步骤(1)至(2)实现，包括：After the user equipment selects the first D-PUR, the user equipment transmits the target data to the base station through the first D-PUR. In addition, the target data can be data in a control plane (CP) solution or data in a user plane (UP) solution. When the target data is the data in the control plane solution, referring to Fig. 3, the process of the user equipment transmitting the target data to the base station can be implemented through the following steps (1) to (2), including:

(1)用户设备通过第一D-PUR向基站发送无线资源控制数据早期传输请求(Radio Resource Control Early Data Request，RRCEarlyDataRequest)。(1) The user equipment sends a radio resource control data early transmission request (Radio Resource Control Early Data Request, RRCEarly Data Request) to the base station through the first D-PUR.

该RRCEarlyDataRequest包括该用户设备的设备标识、建立原因值establishmentCause、专用非接入层(Non-Access Stratrum,NAS)消息dedicatedInfoNAS。The RRCEarlyDataRequest includes the device identifier of the user equipment, the establishment cause value establishmentCause, and the dedicated Non-Access Stratum (NAS) message dedicatedInfoNAS.

其中，设备标识可以为临时移动用户标识(Serving-Temporary Mobile Subscriber Identity，S-TMSI)。该establishmentCause用于表示用户设备的访问类型；dedicatedInfoNAS携带该目标数据。The device identifier may be a temporary mobile subscriber identity (Serving-Temporary Mobile Subscriber Identity, S-TMSI). The establishmentCause is used to indicate the access type of the user equipment; the dedicatedInfoNAS carries the target data.

如果基站接收到用户设备的目标数据，且目标数据是完整的，则基站会向用户设备返回用于指示传输成功的控制消息；如果基站接收到该目标数据，但目标数据是不完整的，则基站会向用户设备返回用于指示传输失败的控制消息；如果基站没有接收到该目标数据，则基站不会向用户设备返回任何消息。相应的，步骤(1)之后，还包括步骤(2)：If the base station receives the target data of the user equipment and the target data is complete, the base station will return to the user equipment a control message indicating the success of the transmission; if the base station receives the target data but the target data is incomplete, then The base station will return a control message for indicating transmission failure to the user equipment; if the base station does not receive the target data, the base station will not return any message to the user equipment. Correspondingly, after step (1), it also includes step (2):

(2)基站向用户设备返回控制消息。(2) The base station returns a control message to the user equipment.

该控制消息可以为RRC(Radio Resource Control，无线资源控制)消息；并且，当目标数据传输成功时，该控制消息可以为无线资源控制数据早期传输完成(Radio Resource Control Early Data Complete，RRCEarlyDataComplete)消息。该RRCEarlyDataComplete消息用于指示目标数据传输成功；并且，该RRCEarlyDataComplete消息可以携带专用的下行NAS消息；该下行NAS消息携带待传输的下行数据。当目标数据传输失败时，该控制消息可以为无线资源控制连接拒绝(Radio Resource Control Connection Reject，RRCConnectionReject)消息，该RRCConnectionReject消息指示目标数据传输失败。The control message may be an RRC (Radio Resource Control, Radio Resource Control) message; and, when the target data is successfully transmitted, the control message may be a Radio Resource Control Early Data Complete (RRCEarlyDataComplete) message. The RRCEarlyDataComplete message is used to indicate that the target data is successfully transmitted; and the RRCEarlyDataComplete message may carry a dedicated downlink NAS message; the downlink NAS message carries the downlink data to be transmitted. When the target data transmission fails, the control message may be a Radio Resource Control Connection Reject (RRCConnectionReject) message, and the RRCConnectionReject message indicates that the target data transmission fails.

当目标数据为用户面方案中的数据时，参见图4，用户设备向基站传输目标数据的过程可以通过以下步骤(A)至(B)实现，包括：When the target data is the data in the user plane solution, referring to Figure 4, the process of the user equipment transmitting the target data to the base station can be implemented through the following steps (A) to (B), including:

(A)用户设备通过第一D-PUR向基站发送无线资源控制连接恢复请求(Radio Resource Control Connection Resume Request，RRCConnectionResumeRequest)和目标数据。(A) The user equipment sends a radio resource control connection recovery request (Radio Resource Control Connection Resume Request, RRCConnectionResumeRequest) and target data to the base station through the first D-PUR.

该RRCConnectionResumeRequest包括用户设备的设备标识、恢复原因值(resumeCause)和恢复消息完整性认证码(short Resume Message Authentication Code Integrity，shortResumeMAC-I)。The RRCConnectionResumeRequest includes the device identifier of the user equipment, the resume cause value (resumeCause), and the resume message integrity authentication code (short Resume Message Authentication Code Integrity, shortResumeMAC-I).

其中，该设备标识可以为该设备的resumeID，恢复原因值用于表示用户设备的访问类型，恢复消息完整性认证码用于识别和验证用户设备。The device identifier may be the resumeID of the device, the recovery reason value is used to indicate the access type of the user equipment, and the recovery message integrity authentication code is used to identify and verify the user equipment.

(B)基站向用户设备返回控制消息。(B) The base station returns a control message to the user equipment.

控制消息可以为RRC消息；并且，当目标数据传输成功时，该控制消息可以为无线资源控制连接释放(Radio Resource Control Connection Release，RRCConnectionRelease)消息和待传输的下行数据。其中，该RRCConnectionRelease消息可以包括释放原因值releaseCause、用户设备的设备标识、下一跳链接计数器(Next Hop Chaining Counter，NCC)。当目标数据传输失败时，该控制消息可以为RRCConnectionReject消息。The control message may be an RRC message; and, when the target data is successfully transmitted, the control message may be a radio resource control connection release (Radio Resource Control Connection Release, RRCConnectionRelease) message and downlink data to be transmitted. The RRCConnectionRelease message may include the release cause value releaseCause, the device identifier of the user equipment, and the Next Hop Chaining Counter (NCC). When the target data transmission fails, the control message may be an RRCConnectionReject message.

在本申请实施例中，用户设备可以直接通过D-PUR向基站传输目标数据，不需要向基站发送随机接入请求，接收基站的随机接入响应后，再向基站传输目标数据，简化了接入步骤，能够提高数据的传输效率。In the embodiment of the present application, the user equipment can directly transmit target data to the base station through D-PUR without sending a random access request to the base station. After receiving the random access response from the base station, the user equipment transmits the target data to the base station, which simplifies the connection. Entering steps can improve the efficiency of data transmission.

需要说明的一点是，目标数据存储在缓冲区中，以在目标数据传输失败时从缓冲区中提取目标数据，重新向基站传输该目标数据。其中，缓冲区可以为HARQ buffer(Hybrid Automatic Repeat request buffer，混合自动重传请求缓冲区)。相应的，用户设备可以将目标数据以MACPDU(Media Access Control Packet Data Unit，媒体接入控制层协议数据单元)的形式，存储到HARQ buffer中。其中，用户设备可以在向基站传输目标数据时，将目标数据存储在缓冲区中；也可以在向基站传输目标数据之后，将目标数据存储在缓冲区中；也可以在向基站传输目标数据之前，将目标数据存储在缓冲区中，在本申请实施例中，不对存储目标数据的时间做具体限定。One point that needs to be explained is that the target data is stored in the buffer, so that when the target data transmission fails, the target data is extracted from the buffer, and the target data is retransmitted to the base station. Among them, the buffer may be HARQ buffer (Hybrid Automatic Repeat request buffer, hybrid automatic repeat request buffer). Correspondingly, the user equipment may store the target data in the HARQ buffer in the form of MACPDU (Media Access Control Packet Data Unit, Media Access Control Layer Protocol Data Unit). Among them, the user equipment may store the target data in the buffer when transmitting the target data to the base station; it may also store the target data in the buffer after transmitting the target data to the base station; or it may store the target data in the buffer before transmitting the target data to the base station. , The target data is stored in the buffer. In the embodiment of the present application, the time for storing the target data is not specifically limited.

在本申请实施例中，在目标数据传输失败时，用户设备还可以从缓冲区中提取目标数据，进而进行目标数据的重传，提高了目标数据传输的可靠性。In the embodiment of the present application, when the target data transmission fails, the user equipment can also extract the target data from the buffer, and then retransmit the target data, which improves the reliability of the target data transmission.

需要说明的另一点是，在本申请实施例中，如果目标数据传输失败，用户设备可以自动选取D-PUR进行目标数据的重传；因此，步骤201可以是用户设备首次向基站传输目标数据的过程，也可以为用户设备向基站重新传输目标数据的过程。Another point that needs to be explained is that in this embodiment of the application, if the target data transmission fails, the user equipment can automatically select D-PUR to retransmit the target data; therefore, step 201 may be the first time the user equipment transmits the target data to the base station. The process can also be a process in which the user equipment retransmits the target data to the base station.

步骤202：用户设备确定目标数据的传输结果，该传输结果为传输成功或者传输失败。Step 202: The user equipment determines the transmission result of the target data, and the transmission result is the transmission success or the transmission failure.

用户设备向基站传输目标数据之后，基站会根据对目标数据的接收结果，向用户设备返回控制消息或者不返回任何消息。因此，用户设备可以根据预设时长内基站的反馈信息确定目标数据的传输结果。After the user equipment transmits the target data to the base station, the base station will return a control message to the user equipment or not return any message according to the result of receiving the target data. Therefore, the user equipment can determine the target data transmission result according to the feedback information of the base station within the preset time period.

第一种实现方式，如果用户设备没有接收到基站返回的反馈信息，则认为此次的目标数据传输失败；相应的，本步骤可以为：如果用户设备向基站传输目标数据之后的预设时长内没有接收到基站返回的反馈信息，则用户设备确定目标数据传输失败。In the first implementation manner, if the user equipment does not receive the feedback information returned by the base station, it is considered that the target data transmission this time has failed; accordingly, this step can be: if the user equipment transmits the target data to the base station within a preset period of time If the feedback information returned by the base station is not received, the user equipment determines that the target data transmission fails.

其中，预设时长的控制可以通过定时器来实现，当用户设备向基站传输目标数据时，启动定时器，该定时器的定时时长为该预设时长。若定时器超时，用户设备还未收到基站的反馈信息，则用户设备确定目标数据传输失败；若定时器未超时，用户设备接收到基站的反馈信息，则用户设备可以根据基站的反馈信息，确定目标数据的传输结果为传输成功或者传输失败。当目标数据传输成功或者传输失败时，停止定时器。Wherein, the control of the preset duration may be realized by a timer. When the user equipment transmits target data to the base station, the timer is started, and the timing duration of the timer is the preset duration. If the timer expires and the user equipment has not received the feedback information from the base station, the user equipment determines that the target data transmission has failed; if the timer does not expire and the user equipment receives the feedback information from the base station, the user equipment can, according to the feedback information from the base station, Determine whether the transmission result of the target data is successful or failed. When the target data transmission is successful or the transmission fails, the timer is stopped.

在本申请实施例中，用户设备根据预设时长内基站的反馈信息确定目标数据是否传输失败，较为简单。In the embodiment of the present application, it is relatively simple for the user equipment to determine whether the target data transmission fails according to the feedback information of the base station within the preset time period.

第二种实现方式，如果用户设备接收到基站返回的反馈信息，则根据反馈信息，确定目标数据的传输结果。相应的，本步骤可以为：如果用户设备向基站传输目标数据之后的预设时长内接收到基站返回的用于指示目标数据传输失败的控制消息，则用户设备确定目标数据传输失败。In the second implementation manner, if the user equipment receives the feedback information returned by the base station, it determines the transmission result of the target data according to the feedback information. Correspondingly, this step may be as follows: if the user equipment receives a control message returned by the base station within a preset period of time after transmitting the target data to the base station for indicating the target data transmission failure, the user equipment determines that the target data transmission fails.

其中，在一种可能的实现方式中，控制消息包括RRC消息，用户设备可以根据RRC消息，确定目标数据的传输结果。例如，RRC消息可以为控制面方案中的RRCEarlyDataComplete消息，该RRCEarlyDataComplete消息指示目标数据传输成功。RRC消息还可以为用户面方案中的RRCConnectionRelease消息，该RRCConnectionRelease消息指示目标数据传输成功。RRC消息还可以为RRCConnectionReject消息，该RRCConnectionReject消息用于指示目标数据传输失败。Among them, in a possible implementation manner, the control message includes an RRC message, and the user equipment can determine the transmission result of the target data according to the RRC message. For example, the RRC message may be an RRCEarlyDataComplete message in the control plane solution, and the RRCEarlyDataComplete message indicates that the target data transmission is successful. The RRC message may also be an RRCConnectionRelease message in the user plane solution, and the RRCConnectionRelease message indicates that the target data transmission is successful. The RRC message may also be an RRCConnectionReject message, and the RRCConnectionReject message is used to indicate that the target data transmission fails.

基站可以通过PDCCH(Physical Downlink Control Channel，物理下行控制信道)向用户发送控制消息；用户设备监听PDCCH调度，PDCCH可以调度PDSCH(Physical Downlink Shared Channel，物理下行共享信道)，根据PDSCH中包括的RRC消息，确定目标数据的传输结果。相应的，如果用户设备向基站传输目标数据之后的预设时长内接收到基站返回的用于指示目标数据传输失败的控制消息，则用户设备确定目标数据传输失败的步骤可以为：如果用户设备向基站传输目标数据之后的预设时长内接收到基站通过物理下行控制信道PDCCH发送的物理下行共享信道PDSCH消息，且PDSCH消息中包括用于指示目标数据传输失败的RRC消息时，确定目标数据传输失败。The base station can send control messages to the user through the PDCCH (Physical Downlink Control Channel); the user equipment monitors the PDCCH scheduling, and the PDCCH can schedule the PDSCH (Physical Downlink Shared Channel) according to the RRC message included in the PDSCH , To determine the transmission result of the target data. Correspondingly, if the user equipment receives the control message returned by the base station for indicating the failure of the target data transmission within a preset time period after the user equipment transmits the target data to the base station, the step of the user equipment determining that the target data transmission fails may be: When the base station receives the physical downlink shared channel PDSCH message sent by the base station through the physical downlink control channel PDCCH within a preset time period after the base station transmits the target data, and the PDSCH message includes an RRC message for indicating the target data transmission failure, it is determined that the target data transmission fails .

在本申请实施例中，用户设备可以通过基站发送的控制消息确定目标数据传输成功或者传输失败，从而根据目标数据的传输结果重新传输或者停止传输目标数据，提高数据传输的效率和数据传输的可靠性。In the embodiment of the present application, the user equipment can determine whether the target data transmission succeeds or fails through the control message sent by the base station, thereby retransmitting or stopping the transmission of the target data according to the transmission result of the target data, thereby improving the efficiency of data transmission and the reliability of data transmission. Sex.

其中，在另一种可能的实现方式中，基站可以通过PDCCH调度的上行重传向基站重新传输目标数据。用户设备监听PDCCH调度，PDCCH可以调度上行重传，用户设备可以通过PDCCH指示的动态资源向基站重新传输目标数据。其中，控制消息包括上行重传控制消息，相应的，用户设备根据上行重传控制消息，向基站重新传输目标数据的步骤可以为：如果用户设备向基站传输目标数据之后的预设时长内接收到基站发送的PDCCH消息，且PDCCH 消息中包括用于指示目标数据传输失败的上行重传控制消息，且上行重传控制消息中包括UL grant(Uplink grant，上行调度许可)的资源标识；通过UL grant的资源标识对应的UL grant资源向基站重新传输目标数据。Among them, in another possible implementation manner, the base station may retransmit the target data to the base station through the uplink retransmission scheduled by the PDCCH. The user equipment monitors the PDCCH scheduling, the PDCCH can schedule uplink retransmission, and the user equipment can retransmit target data to the base station through the dynamic resources indicated by the PDCCH. Wherein, the control message includes an uplink retransmission control message. Correspondingly, the step of the user equipment retransmitting the target data to the base station according to the uplink retransmission control message may be as follows: if the user equipment transmits the target data to the base station within a preset time period after receiving the target data The PDCCH message sent by the base station, and the PDCCH message includes an uplink retransmission control message for indicating the failure of target data transmission, and the uplink retransmission control message includes the resource identifier of UL grant (Uplink grant, uplink scheduling permission); through UL grant The UL grant resource corresponding to the resource identifier retransmits the target data to the base station.

在本申请实施例中，用户设备也可以根据基站发送的上行重传控制消息，获取基站为用户设备配置的动态资源，向基站重新传输目标数据，提高数据传输的可靠性。In the embodiment of the present application, the user equipment may also obtain the dynamic resources configured by the base station for the user equipment according to the uplink retransmission control message sent by the base station, and retransmit the target data to the base station, thereby improving the reliability of data transmission.

需要说明的一点是，如果用户设备确定目标数据的传输结果为传输成功，则用户设备不再执行步骤203和步骤204；如果用户设备确定目标数据的传输结果为传输失败，用户设备才执行步骤203和步骤204。It should be noted that if the user equipment determines that the transmission result of the target data is a successful transmission, the user equipment does not perform

steps

203 and 204; if the user equipment determines that the transmission result of the target data is a transmission failure, the user equipment only executes step 203 And step 204.

步骤203：如果目标数据传输失败，用户设备获取第二D-PUR。Step 203: If the target data transmission fails, the user equipment obtains the second D-PUR.

如果目标数据传输失败，用户设备能够自行获取第二D-PUR，通过该第二D-PUR重新向基站传输目标数据。用户设备获取第二D-PUR时，主要有以下两种情况：If the target data transmission fails, the user equipment can acquire the second D-PUR by itself, and retransmit the target data to the base station through the second D-PUR. When the user equipment obtains the second D-PUR, there are mainly the following two situations:

第一：当前，基站为用户设备配置的D-PUR中仍有可用的D-PUR。First: Currently, there are still available D-PURs among the D-PURs configured by the base station for the user equipment.

相应的，用户设备获取第二D-PUR的步骤可以为：如果第一D-PUR所属的多个D-PUR中存在可用的D-PUR，用户设备从多个D-PUR中选择可用的第二D-PUR。Correspondingly, the step for the user equipment to obtain the second D-PUR may be: if there are available D-PURs among the multiple D-PURs to which the first D-PUR belongs, the user equipment selects the available first D-PUR from the multiple D-PURs Two D-PUR.

在本申请实施例中，如果目标数据传输失败，用户设备能够自行获取可用的D-PUR，向基站重新传输目标数据，不需要基站再为用户设备分配动态资源，能够有效利用现有资源，减少数据丢失，提高数据传输的可靠性。In the embodiment of this application, if the target data transmission fails, the user equipment can obtain the available D-PUR on its own and retransmit the target data to the base station. There is no need for the base station to allocate dynamic resources to the user equipment, which can effectively utilize existing resources and reduce Data loss improves the reliability of data transmission.

其中，可用的D-PUR可能有多个，用户设备从多个可用的D-PUR中选择一个可用的第二D-PUR即可。用户设备可以从多个可用的D-PUR中随机选择一个可用的第二D-PUR，也可以选择最近可用的D-PUR。相应的，用户设备从多个D-PUR中选择可用的第二D-PUR的步骤可以为：用户设备从多个D-PUR中选择离第一D-PUR最近，且未使用的第二D-PUR。Among them, there may be multiple available D-PURs, and the user equipment may select one available second D-PUR from multiple available D-PURs. The user equipment can randomly select an available second D-PUR from multiple available D-PURs, or can select the most recently available D-PUR. Correspondingly, the step of the user equipment selecting the available second D-PUR from the multiple D-PURs may be: the user equipment selects the unused second D-PUR closest to the first D-PUR from the multiple D-PURs -PUR.

在本申请实施例中，用户设备从多个D-PUR中选择最近可用的D-PUR，能够快速获取D-PUR，向基站重新传输目标数据，提高数据传输的效率。In the embodiment of the present application, the user equipment selects the most recently available D-PUR from a plurality of D-PURs, can quickly obtain the D-PUR, retransmit the target data to the base station, and improve the efficiency of data transmission.

用户设备也可以根据D-PUR的TB size和目标数据的数据量，选择可用的D-PUR。相应的，用户设备从多个D-PUR中选择可用的第二D-PUR的步骤还可以为：用户设备根据目标数据的数据量，从多个D-PUR中选择与目标数据的数据量匹配的，且未使用的第二D-PUR。例如，用户设备可以根据D-PUR的TB size，即D-PUR能够传输的最大数据量，以及目标数据的数据量，从多个D-PUR中选择TB size略大于目标数据的数据量，且未使用的第二D-PUR。The user equipment can also select the available D-PUR according to the TB size of the D-PUR and the data volume of the target data. Correspondingly, the step of the user equipment selecting the available second D-PUR from the multiple D-PURs may also be: the user equipment selects the data volume of the target data from the multiple D-PURs according to the data volume of the target data. The second D-PUR that is not used. For example, the user equipment can select from multiple D-PURs a TB size slightly larger than the data amount of the target data according to the TB size of the D-PUR, that is, the maximum data volume that the D-PUR can transmit and the data volume of the target data, and Unused second D-PUR.

在本申请实施例中，用户设备根据目标数据的数据量选择与目标数据的数据量匹配的D-PUR，不仅能够保证目标数据通过D-PUR完整的传输，提高数据传输的可靠性，还能够合理利用资源，减少资源浪费。In the embodiment of the present application, the user equipment selects the D-PUR matching the data volume of the target data according to the data volume of the target data, which can not only ensure the complete transmission of the target data through the D-PUR, and improve the reliability of data transmission, but also Use resources rationally and reduce waste of resources.

第二：当前，基站为用户设备配置的D-PUR中没有可用的D-PUR。Second: Currently, there is no available D-PUR among the D-PUR configured by the base station for the user equipment.

如果当前基站为用户设备配置的D-PUR中没有可用的D-PUR，用户设备可以接收基站为用户设备重新分配的D-PUR，从基站为用户设备重新分配的D-PUR中选择可用的D-PUR。相应的，用户设备获取第二D-PUR的步骤还可以为：如果第一D-PUR所属的多个D-PUR中不存在可用的D-PUR，用户设备接收基站重新分配的D-PUR；从基站重新分配的D-PUR中选择可用的第二D-PUR。If there is no available D-PUR in the D-PUR configured by the base station for the user equipment, the user equipment can receive the D-PUR re-allocated by the base station for the user equipment, and select the available D-PUR from the D-PUR re-allocated for the user equipment by the base station. -PUR. Correspondingly, the step for the user equipment to obtain the second D-PUR may also be: if there is no available D-PUR among the multiple D-PURs to which the first D-PUR belongs, the user equipment receives the D-PUR re-allocated by the base station; Select the available second D-PUR from the D-PUR re-allocated by the base station.

如果第一D-PUR所属的多个D-PUR中不存在可用的D-PUR，用户设备可以向基站发送配置请求，用于请求基站重新配置可用的D-PUR；基站响应用户设备的配置请求，为用户设备重新分配至少一个可用的D-PUR；用户设备接收基站重新分配的至少一个D-PUR，从基站重新分配的至少一个D-PUR中选择可用的第二D-PUR。其中，用户设备可以从基站重新分配的至少一个D-PUR中随机选择一个可用的第二D-PUR；用户设备也可以从基站重新分配的至少一个D-PUR中选择一个离上一个被使用的D-PUR最近的第二D-PUR；用户设备也可以从基站重新分配的至少一个D-PUR中选择与目标数据的数据量匹配的第二D-PUR。If there is no available D-PUR among the multiple D-PURs to which the first D-PUR belongs, the user equipment may send a configuration request to the base station to request the base station to reconfigure the available D-PUR; the base station responds to the configuration request of the user equipment , Re-allocate at least one available D-PUR for the user equipment; the user equipment receives the at least one D-PUR re-allocated by the base station, and selects the available second D-PUR from the at least one D-PUR re-allocated by the base station. Among them, the user equipment can randomly select an available second D-PUR from the at least one D-PUR re-allocated by the base station; the user equipment can also select a second D-PUR that is less than the last used D-PUR from the at least one D-PUR re-allocated by the base station. The second D-PUR closest to the D-PUR; the user equipment may also select the second D-PUR matching the data amount of the target data from at least one D-PUR re-allocated by the base station.

在本申请实施例中，如果没有可用的D-PUR，用户设备还可以选择基站为用户设备重新配置的D-PUR，继续向基站重新传输目标数据，减少数据丢失，提高数据传输的可靠性。In the embodiment of this application, if there is no available D-PUR, the user equipment can also select the D-PUR reconfigured by the base station for the user equipment, and continue to retransmit the target data to the base station, reducing data loss and improving the reliability of data transmission.

步骤204、用户设备通过第二D-PUR向基站重新传输目标数据。Step 204: The user equipment retransmits the target data to the base station through the second D-PUR.

缓冲区中存储有目标数据，相应的，本步骤可以为：用户设备从缓冲区中提取传输失败的目标数据，通过第二D-PUR向基站重新传输目标数据。其中，缓冲区可以为HARQ buffer。用户设备通过第二D-PUR向基站重新传输目标数据的步骤与步骤201相似，在此不再赘述。The target data is stored in the buffer. Correspondingly, this step may be: the user equipment extracts the target data whose transmission fails from the buffer, and retransmits the target data to the base station through the second D-PUR. Among them, the buffer can be HARQ buffer. The step for the user equipment to retransmit the target data to the base station through the second D-PUR is similar to step 201, and will not be repeated here.

需要说明的一点是，如果目标数据重传成功，则用户设备可以向基站传输下一个目标数据；如果目标数据重传失败，则用户设备还可以获取第三D-PUR，通过第三D-PUR向基站重新传输该目标数据，直到目标数据传输成功；或者目标数据的传输次数达到预设次数为止。其中，用户设备确定目标数据是否重传成功的步骤和用户设备确定目标数据是否传输成功的步骤相似；并且，用户设备获取第三D-PUR的步骤和用户设备获取第二D-PUR的步骤相似，在此不再进行赘述。One thing to note is that if the target data retransmission is successful, the user equipment can transmit the next target data to the base station; if the target data retransmission fails, the user equipment can also obtain the third D-PUR through the third D-PUR The target data is retransmitted to the base station until the target data is successfully transmitted; or the number of target data transmissions reaches the preset number of times. Wherein, the step of determining whether the target data is retransmitted successfully by the user equipment is similar to the step of determining whether the target data is successfully transmitted by the user equipment; and the step of obtaining the third D-PUR by the user equipment is similar to the step of obtaining the second D-PUR by the user equipment , I won’t repeat it here.

需要说明的另一点是，用户设备还可以及时删除缓冲区中的目标数据；其中，用户删除缓冲区中的目标数据的实际有以下三种：Another point that needs to be explained is that the user equipment can also delete the target data in the buffer in a timely manner; among them, the user actually deletes the target data in the buffer in the following three ways:

第一：当目标数据传输成功时，用户设备删除缓冲区中的目标数据。First: When the target data is successfully transmitted, the user equipment deletes the target data in the buffer.

当目标数据传输成功时，用户设备不需要继续缓存该目标数据，因此可以删除缓冲区中的目标数据，从而释放缓冲区的存储空间，便于存储其他没有传输成功的数据。When the target data transmission is successful, the user equipment does not need to continue to cache the target data, so the target data in the buffer can be deleted, thereby freeing up the storage space of the buffer and facilitating storage of other data that has not been successfully transmitted.

第二：当多个D-PUR中不存在可用的D-PUR时，用户设备删除缓冲区中的目标数据。Second: When there is no available D-PUR among the multiple D-PURs, the user equipment deletes the target data in the buffer.

如果基站当前为用户设备配置的多个D-PUR中不存在可用的D-PUR，目标数据无法通过D-PUR向基站重新传输数据，则用户设备可以删除缓冲区中的目标数据。If there is no available D-PUR among the multiple D-PURs currently configured by the base station for the user equipment, and the target data cannot be retransmitted to the base station through the D-PUR, the user equipment may delete the target data in the buffer.

需要说明的一点是，当多个D-PUR中不存在可用的D-PUR时，用户设备也可以先不删除缓冲区中的目标数据，接收基站为用户设备重新配置的D-PUR，通过该重新配置的D-PUR向基站传输目标数据，直到目标数据传输成功时，才删除缓冲区中的目标数据。One thing to note is that when there is no available D-PUR among multiple D-PURs, the user equipment can also receive the D-PUR reconfigured by the base station for the user equipment without deleting the target data in the buffer. The reconfigured D-PUR transmits target data to the base station, and does not delete the target data in the buffer until the target data transmission is successful.

在本申请实施例中，在没有可用的D-PUR时，用户设备可以删除缓冲区中的目标数据，不再向基站重新传输目标数据，减少传输失败的目标数据对资源的持续占用，减少资源浪费。用户设备也可以接收基站为用户设备重新配置的D-PUR，再通过重新配置的D-PUR，向基站重新传输目标数据，减少数据丢失，提高数据传输的可靠性。In the embodiment of the present application, when there is no available D-PUR, the user equipment can delete the target data in the buffer and no longer retransmit the target data to the base station, reducing the continuous occupation of resources by the target data that fails to transmit, and reducing resources waste. The user equipment may also receive the D-PUR reconfigured by the base station for the user equipment, and then retransmit the target data to the base station through the reconfigured D-PUR, thereby reducing data loss and improving the reliability of data transmission.

第三：当目标数据的重传次数达到预设次数时，用户设备删除缓冲区中的目标数据。Third: When the number of retransmissions of the target data reaches the preset number of times, the user equipment deletes the target data in the buffer.

用户设备还可以控制目标数据的重传次数，当目标数据的重传次数达到预设次数时，用户设备不再向基站重新传输该目标数据，删除缓冲区中的目标数据。预设次数可以为一个设置的合理数值，例如，预设次数为5、10等合理数值；预设次数也可以根据时延和定时器的超时时间进行设定，在此不做具体限定。The user equipment can also control the number of retransmissions of the target data.
