Description

Technology Field

[0001] [Reference to related applications]

[0002] This application claims priority to Chinese Patent Application No. 202011149169.5, filed in China on October 23, 2020, with the title of the invention "Data transmission method, device and apparatus," and incorporates the entire contents of the application by reference.

[0003] The present disclosure relates to the field of mobile communication technology, and in particular to data transmission methods, devices, and equipment. Background Technology

[0004] In the current transmission mechanism, data packets are passed from the Medium Access Control (MAC) layer to the physical layer and then transmitted to network devices based on configured grant resources; however, transmission of the data packet may be halted after a portion has been transmitted. After transmission of the data packet is halted, the User Equipment (UE) initiates the Configured Grant Timer (CGT) and / or the Configured Grant Retransmission Timer (CGRT) at the MAC layer.

[0005] If a network device successfully receives the data packet, in an NR-unlicensed spectrum (NR-U) scenario, the network side provides Downlink Feedback Information (DFI), indicating that the data has been successfully received; if the network device fails to receive it successfully, in an Industrial Internet of Things (IIoT) scenario, the network side sends a retransmission schedule to the UE. However, because the UE cannot receive the network side's DFI or retransmission schedule due to channel issues or other causes, the UE may only be able to perform data transmission after the timer has expired. This increases transmission delay, and such increased delay can have a severe impact on traffic performance, especially when the traffic is IIoT traffic.

[0090] Among them, the method and apparatus are based on the same application concept, and since the principles by which the method and apparatus solve the problem are similar, the implementation of the apparatus and method may be mutually referenced, and the overlapping parts will not be described in further detail.

[0091] Furthermore, the technical solution provided in the embodiments of the present disclosure may be applied to various systems, and in particular to 5G systems. For example, the applicable systems may be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD) system, a long term evolution advanced (LTE-A) system, a universal mobile telecommunication system (UMTS), a worldwide interoperability for microwave access (WiMAX) system, a 5G New Radio (NR) system, etc. All of these various systems include terminal devices and network devices. The system may further include core network parts such as the Evolved Packet System (EPS) and the 5G system (5GS).

[0092] The terminal device described in the embodiments of the present disclosure may mean a device that provides voice and / or data connectivity to a user, a handheld device having wireless connectivity capabilities, or other processing device connected to a wireless modem processor. In different systems, the name of the user device may not be the same; for example, in a 5G system, the terminal device may be referred to as the user device. The wireless terminal device may communicate with one or more core networks (CN) via a radio access network (RAN), and the wireless terminal device may be a mobile terminal device such as a mobile phone (or "cellular" phone) and a computer equipped with a mobile terminal device, for example, a portable, pocket-type, grip-type, installed inside a computer, or a mobile device mounted on a vehicle, and these exchange language and / or data with the radio access network. For example, devices such as Personal Communication Service (PCS) telephones, wireless telephones, Session Initiated Protocol (SIP) transceivers, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal devices may be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, user devices, etc., but the embodiments of the present disclosure are not limited thereto.

[0093] The network device described in the embodiments of the present disclosure may be a base station, and said base station may include a plurality of cells that provide services for a terminal. Depending on the specific application scenario, the base station may also be referred to as an access point and may be a device that communicates with a wireless terminal device through one or more sectors at an air interface of an access network, or may be called by other names. The network device may be used as a router between the wireless terminal device and the rest of the access network to exchange received air frames and Internet Protocol (IP) packets, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device described in the embodiments of the present disclosure may be a network device (Base Transceiver Station, BTS) in a Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a network device (NodeB) in a Wide-band Code Division Multiple Access (WCDMA), an evolutionary network device (eNB or e-NodeB) in a long-term evolution (LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved node (HeNB), a relay node, a femto base station, a pico base station, etc., but the embodiments of the present disclosure are not limited thereto.In some network structures, network devices may include centralized unit (CU) nodes and distributed unit (DU) nodes, and the centralized unit and the distributed unit may be installed geographically separated.

[0094] Multi-Input Multi-Output (MIMO) transmission can be performed between network devices and terminal devices using one or more antennas respectively, and the MIMO transmission can be Single User MIMO (SU-MIMO) or Multi-User MIMO (MU-MIMO). Depending on the type and quantity of antenna combinations, the MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, and can also be diversity transmission, precoding transmission, or beamforming transmission. First, the existing transmission mechanism is described. In a Configured Grant (CG), unlike dynamic scheduling which allocates radio resources once per slot / Transmission Timing Interval (TTI) for a UE (as specified by the Physical Downlink Control Channel (PDCCH)), the Configured Grant supports semi-static configuration of radio resources and can periodically allocate the resources to specific UEs. That is, the network side notifies the UE that a resource is periodically available and can periodically notify the location of the resource through Radio Resource Control (RRC) signaling. The network side may also notify the UE of information such as the location of the resource in the frequency domain, start and end times, and the Modulation Coding Scheme (MCS). By doing so, the network side reduces PDCCH notification overhead through periodic resource allocation.

[0095] The configuration grant scheduling method is applied to Voice Over IP (VoIP) and some Ultra Reliable Low Latency Communications (URLLC) traffic that includes periodic control signaling. Configuration grant is a single uplink scheduling method, and there are two types: type 1 and type 2.

[0096] In Type 1, RRC distributes periodic resources, and after RRC configuration, the resources become active; that is, after the UE receives the RRC configuration message, it can use the resources to transmit uplink data.

[0097] In Type 2, RRC allocates periodic resources, but since the initial state is inactive, the network side must activate the resource via physical layer signaling and deactivate the resource via Downlink Control Information (DCI) after data transmission is terminated. Similarly, configuration information of partial configuration grants can be modified via physical layer signaling, for example, by modifying the resource's location information in the time-frequency domain.

[0098] In the case of CGT, for New Radio (NR), there is no Downlink (DL) feedback for Uplink (UL) data transmission. If UL transmission fails, the network side sends a retransmission scheduling command via PDCCH; however, if the network side were to provide feedback via PDCCH when UL data transmission succeeds, the objective of saving PDCCH overhead cannot be achieved. Therefore, a single CGT is defined, and the corresponding timer starts after the UE transmits a data packet. If the UE receives a retransmission scheduling from the relevant Hybrid Automatic Repeat Request (HARQ) process before the CGT times out, the UE performs the retransmission operation. If the UE does not receive a retransmission scheduling from the network side, the UE recognizes that the data transmission was successful after the CGT times out.

[0099] Regarding CGRT, CGRT was introduced in NR-U because, in NR-U, the Identity Document (ID) of the HARQ process is autonomously selected by the UE, and since retransmission scheduling cannot be performed if the network side cannot receive the UE's data packet, the mechanism introduced in NR-U is for the network side to send feedback signaling (DFI) to the UE. However, since the NR-U channel is preemptive, the UE may not receive the DFI, so CGRT is introduced. The corresponding timer starts after the UE transmits the data packet. If the UE receives the DFI (correct feedback) before the timer expires, the UE stops the timer; if the timer expires and the UE still does not receive the DFI, the UE performs a retransmission operation.

[0100] In existing transmission mechanisms, when a UE's data packet is transmitted from the MAC layer to the physical layer and the physical layer transmits the data packet, there may be instances where the transmission of the current Protocol Data Unit (PDU) is interfered with, for example, by data transmission preemption.

[0101] For example, referring to Fig. 1, data packet A is transmitted from the MAC layer to the physical layer and starts the timer CGT / CGRT, but preemption occurs at the physical layer, that is, the physical layer transmits data B, which has a relatively high priority, first. Due to causes such as the channel, the UE does not receive the DFI for data packet A transmitted by the network side, so the UE can only retransmit data packet A after the timer CGRT has expired, thereby increasing the delay in data transmission.

[0102] As can be seen, existing transmission mechanisms have a problem in which traffic performance is affected when transmission delay increases. To solve the problem existing in existing transmission mechanisms, embodiments of the present disclosure provide a data transmission method, device, and apparatus.

[0103] FIG. 2 illustrates a flowchart of a data transmission method provided in an embodiment of the present disclosure, wherein the method is applied to a user device, wherein the user device includes a MAC layer of the user device and a physical layer of the user device, and the method includes the following steps.

[0104] In step 201, the Media Access Control (MAC) layer of the user device delivers a first data packet to the physical layer of the user device and starts the Config Grant Timer (CGT) and / or Config Grant Retransmission Timer (CGRT).

[0105] The MAC layer of the user device first transmits a first data packet to the physical layer of the user device, causing the physical layer of the user device to transmit the received first data packet to a network device. After transmitting the first data packet to the physical layer of the user device, the MAC layer of the user device may initiate CGT and / or CGRT.

[0106] In step 202, when the MAC layer of the user device determines that the transmission of the first data packet has stopped at the physical layer of the user device, the CGT and / or CGRT is stopped, and after the CGT and / or CGRT is stopped, the first data packet is transmitted.

[0107] After the MAC layer of the user device delivers the first data packet to the physical layer of the user device, if the physical layer of the user device determines that the transmission of the first data packet has stopped, the CGT and / or CGRT may be stopped. Specifically, if the CGT was started after the first data packet was transmitted before, the CGT is stopped; if the CGRT was started after the first data packet was transmitted before, the CGRT is stopped; and if the CGRT and CGT were started after the first data packet was transmitted before, the CGRT and CGT are stopped. After stopping the CGT and / or CGRT, the MAC layer of the user device may transmit the first data packet. By stopping the CGT and / or CGRT and transmitting the first data packet after the CGT and / or CGRT have been stopped, it is possible to avoid performing a data transmission operation after the timer has exceeded the time, ensure that the user device completes the data transmission in advance, and save delay.

[0108] In an embodiment of the present disclosure, when the MAC layer of a user device transmits a first data packet to the physical layer of the user device and, after starting a CGT and / or CGRT, determines that the transmission of the first data packet has stopped at the physical layer of the user device, the CGT and / or CGRT is stopped, and after the CGT and / or CGRT is stopped, the first data packet is transmitted, thereby avoiding performing a data transmission operation after the timer has exceeded the time, ensuring that the user device completes the data transmission in advance, and saving delay.

[0109] In one selectable embodiment of the present disclosure, the method is,

[0110] The method further includes the step of stopping the transmission of the first data packet and feeding back notification information to the MAC layer of the user device when the physical layer of the user device detects a target scenario while transmitting the first data packet.

[0111] Among them, the MAC layer of the user device determines that the transmission of the first data packet is stopped according to the notification information.

[0112] After the MAC layer of the user device transmits the first data packet to the physical layer of the user device, the physical layer of the user device transmits the received first data packet to a network device. If the physical layer of the user device detects a target scenario while transmitting the first data packet, it stops transmitting the first data packet and feeds back notification information to the MAC layer of the user device that the transmission of the first data packet has stopped. After receiving the notification information fed back by the physical layer of the user device, the MAC layer of the user device can know that the transmission of the first data packet has stopped at the physical layer of the user device. At this time, the MAC layer of the user device stops the CGT and / or CGRT, and after the CGT and / or CGRT has stopped, it can transmit the first data packet.

[0118] When the physical layer of a user device transmits a first data packet, if it obtains a second data packet satisfying preset conditions, it may stop transmitting the first data packet to a network device, wherein the second data packet may be another data packet transmitted by the MAC layer of the user device to the physical layer of the user device, or it may be a data packet generated by the physical layer of the user device itself. That is, in the process of the physical layer of the user device transmitting the first data packet to a network device, if it receives a second data packet satisfying preset conditions transmitted by the MAC layer of the user device, it may stop transmitting the first data packet to the network device. Alternatively, in the process of the physical layer of the user device transmitting the first data packet to a network device, if the physical layer of the user device generates a second data packet satisfying preset conditions, it may stop transmitting the first data packet to the network device.

[0119] When the physical layer of a user device transmits a first data packet, if it receives first instruction information instructing the network device to stop transmitting the first data packet, it may stop transmitting the first data packet to the network device. That is, in the process of the physical layer of the user device transmitting a first data packet to a network device, if it receives first instruction information instructing the network device to stop transmitting the first data packet, it may stop transmitting the first data packet to the network device in accordance with the first instruction information transmitted by the network device.

[0120] When the physical layer of a user device receives second instruction information instructing a slot change of the user device transmitted by a network device while transmitting a first data packet, the transmission of the first data packet to the network device may be stopped. That is, in the process of the physical layer of the user device transmitting a first data packet to a network device, if it receives second instruction information instructing a slot change of the user device transmitted by a network device, the transmission of the first data packet to the network device may be stopped in accordance with the second instruction information transmitted by the network device.

[0121] In an embodiment of the present disclosure, based on the acquisition status of a data packet or instructions from a network device, the transmission of a first data packet to a network device may be stopped, and the transmission of the first data packet may be controlled according to a trigger of a user device or a network device.

[0122] In one selectable embodiment of the present disclosure, when the physical layer of the user device obtains a second data packet satisfying a preset condition when transmitting the first data packet, stopping the transmission of the first data packet is

[0123] When the physical layer of the user device transmits the first data packet, the transmission of the first data packet is stopped if the MAC layer of the user device receives the second Media Access Control Protocol Data Unit (MAC PDU) transmitted by the MAC layer of the user device or if the physical layer of the user device generates uplink control information (UCI).

[0124] Among them, the second data packet is the second MAC PDU or the UCI, the first data packet is the first MAC PDU, the first data packet is transmitted to a network device via a first configuration grant resource, the second data packet is transmitted to the network device via a first target uplink resource, the priority of the second data packet is higher than the priority of the first data packet, and / or the priority of the first target uplink resource is higher than the priority of the first configuration grant resource.

[0125] Since all data packets transmitted by the MAC layer of the user device to the physical layer of the user device are MAC PDUs, the first data packet is the first MAC PDU, and if the second data packet is a data packet transmitted by the MAC layer of the user device to the physical layer of the user device, the second data packet is the second MAC PDU. Among these, the first data packet is transmitted to the network device through the first configuration grant resource, and the second data packet is transmitted to the network device through the first target uplink resource, the configuration grant resource is selected from among the uplink resources, and by periodically using the configuration grant resource, it is possible to implement saving PDCCH overhead.

[0126] If the second data packet is the second MAC PDU, the transmission of the first data packet to the network device may be stopped according to the second data packet satisfying preset conditions, and the specific process may be as follows: when the physical layer of the user device transmits the first data packet, the second MAC PDU delivered by the MAC layer of the user device is received, and if the priority of the second MAC PDU is higher than the priority of the first data packet (first MAC PDU), the transmission of the first data packet may be stopped. The specific process may be as follows: when the physical layer of the user device transmits the first data packet, the second MAC PDU delivered by the MAC layer of the user device is received, and if the priority of the first target uplink resource for transmitting the second MAC PDU is higher than the priority of the first configuration grant resource for transmitting the first data packet, the transmission of the first data packet may be stopped. The specific process may also be as follows, but when the physical layer of the user device transmits the first data packet, the MAC layer of the user device receives the second MAC PDU delivered, and if the priority of the first target uplink resource for transmitting the second MAC PDU is higher than the priority of the first configuration grant resource for transmitting the first data packet, and at the same time the priority of the second MAC PDU is higher than the priority of the first data packet, the transmission of the first data packet may be stopped.

[0127] If the second data packet is Uplink Control Information (UCI) generated by the physical layer of the user device, the transmission of the first data packet to the network device may be stopped according to the second data packet satisfying preset conditions. The specific process may be as follows: when the physical layer of the user device transmits the first data packet, UCI is generated, and if the priority of the UCI generated by the physical layer of the user device is higher than the priority of the first data packet (first MAC PDU), the transmission of the first data packet may be stopped. The specific process may also be as follows: when the physical layer of the user device transmits the first data packet, UCI is generated, and if the priority of the first target uplink resource for transmitting the UCI is higher than the priority of the first configuration grant resource for transmitting the first data packet, the transmission of the first data packet may be stopped. The specific process may also be as follows, wherein when the physical layer of the user device transmits the first data packet, a UCI is generated, and if the priority of the first target uplink resource for transmitting the UCI generated by the physical layer of the user device is higher than the priority of the first configuration grant resource for transmitting the first data packet, and at the same time the priority of the UCI generated by the physical layer of the user device is higher than the priority of the first data packet, the transmission of the first data packet may be stopped.

[0128] In an embodiment of the present disclosure, the transmission of a first data packet may be triggered to stop based on the priority of a second MAC PDU and / or the priority of a first target uplink resource for transmitting the second MAC PDU, and the transmission of a first data packet may also be triggered to stop based on the priority of a UCI and / or the priority of a first target uplink resource for transmitting the UCI, and the transmission of a first data packet may be triggered to stop based on a high priority data and / or uplink resource.

[0129] In one selectable embodiment of the present disclosure, when the physical layer of the user device acquires a second data packet satisfying a preset condition when transmitting the first data packet, the method, after stopping the transmission of the first data packet,

[0130] The physical layer of the user device further includes the step of transmitting the second data packet.

[0131] When the physical layer of a user device transmits a first data packet, if it acquires a second data packet satisfying preset conditions, the physical layer of the user device may stop transmitting the first data packet and then transmit the second data packet to a network device. Here, the second data packet satisfying preset conditions is one in which the priority of the data packet is higher than the priority of the first data packet, and / or the priority of the uplink resource for transmitting said data packet is higher than the priority of the uplink resource for transmitting the first data packet. By transmitting the second data packet to the network device, the physical layer of the user device may implement the transmission of a data packet with a higher priority and / or the transmission of a data packet with a higher priority of the uplink resource.

[0132] In one selectable embodiment of the present disclosure, the step of transmitting the first data packet is,

[0133] A step in which the MAC layer of the user device selects a second target uplink resource among at least one uplink resource; and

[0134] The physical layer of the user device transmits the cached first data packet to a network device via the second target uplink resource;

[0135] When the MAC layer of a user device transmits a first data packet, it must first select a second target uplink resource from among at least one uplink resource, and after determining the second target uplink resource, the user device can transmit the first data packet cached in the MAC layer of the user device to a network device through the second target uplink resource. Specifically, after the MAC layer of the user device determines the second target uplink resource, the physical layer of the user device transmits the first data packet cached in the MAC layer of the user device to a network device through the second target uplink resource determined by the MAC layer of the user device.

[0136] In one selectable embodiment of the present disclosure, the first data packet is first transmitted to the network device through a first configuration grant resource; and the step of the MAC layer of the user device selecting a second target uplink resource among at least one uplink resource comprises:

[0137] The MAC layer of the user device selects the second target uplink resource among the at least one uplink resource according to at least one of the modulation and coding scheme (MCS) of the uplink resource and the reliability parameter of the uplink resource; the method includes the step of.

[0138] When the first data packet is first transmitted to a network device, it is transmitted through a first configuration grant resource, and when the MAC layer of the user device selects a second target uplink resource among at least one uplink resource, the second target uplink resource may be selected among at least one uplink resource according to the MCS of the uplink resource, the second target uplink resource may be selected among at least one uplink resource according to the reliability parameter of the uplink resource, and the second target uplink resource may also be selected among at least one uplink resource according to the MCS of the uplink resource and the reliability parameter of the uplink resource. By selecting the second target uplink resource based on at least one of the MCS of the uplink resource and the reliability parameter of the uplink resource, the method of selecting the second target uplink resource is enriched.

[0139] Among them, the MAC layer of the user device selecting the second target uplink resource among the at least one uplink resource according to at least one of the modulation and coding scheme (MCS) of the uplink resource and the reliability parameter of the uplink resource is,

[0140] A method in which the MAC layer of the user device selects, among the at least one uplink resource, the second target uplink resource in which the MCS is lower than or equal to the MCS corresponding to the first configuration grant resource;

[0141] A method in which the MAC layer of the user device selects, among the at least one uplink resource, the second target uplink resource in which the reliability parameter is higher than or equal to the reliability parameter corresponding to the first configuration grant resource; and

[0142] The MAC layer of the user device selects, among the at least one uplink resource, a second target uplink resource in which the MCS is lower than or equal to the MCS corresponding to the first configuration grant resource and the reliability parameter is higher than or equal to the reliability parameter corresponding to the first configuration grant resource; one of the methods is included.

[0143] When selecting a second target uplink resource based on at least one of the MCS of the uplink resource and the reliability parameter of the uplink resource, one of the following methods may be adopted.

[0144] The MAC layer of the user device may select an uplink resource among at least one uplink resource whose MCS is lower than or equal to the MCS corresponding to the first configuration grant resource, and the selected uplink resource may be set as the second target uplink resource, and at least two uplink resources that meet the requirements according to the MCS may be selected, and when at least two uplink resources that meet the requirements according to the MCS are selected, the first selected uplink resource may be confirmed as the second target uplink resource, and the second target uplink resource may also be selected from among at least two uplink resources that meet the requirements based on a preset strategy.

[0145] The MAC layer of the user device selects an uplink resource among at least one uplink resource whose reliability parameter is higher than or equal to the reliability parameter corresponding to the first configuration grant resource, and sets the selected uplink resource as the second target uplink resource. When selecting at least two uplink resources that meet the requirements according to the reliability parameter, the first selected uplink resource can be confirmed as the second target uplink resource. Additionally, the second target uplink resource can be selected from among at least two uplink resources that meet the requirements based on a preset strategy.

[0146] The MAC layer of the user device selects an uplink resource among at least one uplink resource in which the MCS is lower than or equal to the MCS corresponding to the first configuration grant resource and the reliability parameter is higher than or equal to the reliability parameter corresponding to the first configuration grant resource, and sets the selected uplink resource as the second target uplink resource. When selecting at least two uplink resources that meet the requirements according to the MCS and reliability parameter, the first selected uplink resource can be confirmed as the second target uplink resource. Additionally, the second target uplink resource can be selected from among at least two uplink resources that meet the requirements based on a preset strategy.

[0147] Among these, what needs to be explained is that, due to the reduction in MCS, the reliability of the uplink resource is higher; therefore, an uplink resource is selected whose MCS is lower than or equal to the MCS corresponding to the first configured grant resource. The reliability parameter may be a parameter configured by the network device for the uplink resource, and the higher the reliability, the higher the reliability; for example, it may be a parameter of some level such as 0, 1, 2, or 3. Among these, 0 indicates the lowest reliability, and the higher the number, the higher the reliability.

[0148] In an embodiment of the present disclosure, by selecting a second target uplink resource among uplink resources based on at least one of the MCS and reliability parameters, it is possible to implement the selection of a highly reliable resource on the basis of enriching the selection method of the second target uplink resource.

[0149] In one selectable embodiment of the present disclosure, after the MAC layer of the user device initiates the CGT and / or the CGRT, the method,

[0150] The method further includes the step of setting the MAC layer of the user device to a non-suspended state capable of performing a Hybrid Automatic Retransmission Request (HARQ) process;

[0151] After the MAC layer of the user device stops the CGT and / or CGRT, the method,

[0152] The MAC layer of the user device further includes the step of setting the HARQ process to a paused state in which data to be transmitted is cached; and

[0153] Among them, the MAC layer of the user device sets the HARQ process to a paused state and then transmits the first data packet.

[0154] After initiating the CGT and / or CGRT, the MAC layer of the user device must set the HARQ process to a non-suspended state capable of performing transmission, and by setting the state of the HARQ process, indicate that data in the HARQ cache has already been transmitted. After stopping the CGT and / or CGRT, the MAC layer of the user device must set the HARQ process to a suspended state in which data to be transmitted is cached, and by setting the state of the HARQ process, indicate that there is data to be transmitted in the HARQ cache, and after setting the HARQ process to a suspended state in which data to be transmitted is cached, the cached first data packet can be transmitted.

[0155] Below, a data transmission method provided in an embodiment of the present disclosure is described through two specific steps. When the physical layer of a user device transmits a first data packet and acquires a second data packet satisfying preset conditions, specific steps of the data transmission method may be referenced in FIG. 3.

[0156] In step 301, the MAC layer of the user device generates a first MAC PDU, transmits the first MAC PDU to the physical layer of the user device, and initiates a CGT and / or CGRT to set the HARQ process state to a non-suspended state capable of performing transmission.

[0157] In step 302, the physical layer of the user device transmits the first MAC PDU to the network device through the first configuration grant resource.

[0158] In step 303, when the physical layer of the user device receives the second data packet transmitted by the MAC layer of the user device or when the physical layer of the user device generates the second data packet, the transmission of the first MAC PDU is stopped and the transmission of the second data packet is performed, wherein the priority of the second data packet is higher than the priority of the first MAC PDU, and / or the priority of the first target uplink resource for transmitting the second data packet is higher than the priority of the first configuration grant resource for transmitting the first MAC PDU, and the second data packet is the second MAC PDU or a UCI.

[0159] In step 304, the physical layer of the user device feeds back notification information that the transmission of the first MAC PDU has stopped to the MAC layer of the user device.

[0160] In step 305, the MAC layer of the user device determines, based on the notification information, that the transmission of the first MAC PDU at the physical layer of the user device has stopped, stops the CGT and / or CGRT, and sets the HARQ process to a paused state in which the data to be transmitted is cached.

[0161] In step 306, the MAC layer of the user device selects a second target uplink resource and transmits a first MAC PDU on the second target uplink resource.

[0162] Among them, a transmission mechanism corresponding to the above-described implementation step can be referenced in FIG. 4, and a data packet is transmitted from the MAC layer to the physical layer to initiate CGT and CGRT, but because a transmission interruption occurs at the physical layer (the physical layer transmits other data first or stops the current data transmission according to the instructions of the network device), the MAC layer closes the CGT and CGRT and transmits the data packet to reduce the delay in data transmission.

[0163] When the physical layer of a user device transmits a first data packet, if it receives a first instruction information instructing the network device to stop transmitting the first data packet transmitted or a second instruction information instructing the user device to change its slot, specific steps of the data transmission method may be referenced in FIG. 5.

[0164] In step 501, the MAC layer of the user device generates a first MAC PDU, transmits the first MAC PDU to the physical layer of the user device, and initiates a CGT and / or CGRT to set the HARQ process state to a non-suspended state capable of performing transmission.

[0165] In step 502, the physical layer of the user device transmits the first MAC PDU to the network device through the first configuration grant resource.

[0166] In step 503, if the physical layer of the user device receives first instruction information instructing the interruption of transmission of the first MAC PDU transmitted by the network device, or receives second instruction information instructing the change of the slot of the user device transmitted by the network device, the transmission of the first MAC PDU is stopped.

[0167] In step 504, the physical layer of the user device feeds back notification information to the MAC layer of the user device that the transmission of the first MAC PDU has stopped.

[0168] In step 505, the MAC layer of the user device determines, based on the notification information, that the transmission of the first MAC PDU at the physical layer of the user device has stopped, stops the CGT and / or CGRT, and sets the HARQ process to a paused state in which the data to be transmitted is cached.

[0169] In step 506, the MAC layer of the user device selects a second target uplink resource and transmits a first MAC PDU on the second target uplink resource.

[0170] Among them, the transmission mechanism corresponding to the corresponding implementation step may be referenced in FIG. 4.

[0171] The above describes the entire process of implementing a data transmission method provided in an embodiment of the present disclosure. After the MAC layer of a user device transmits a first data packet to the physical layer of the user device and initiates a CGT and / or CGRT, if the physical layer of the user device determines that the transmission of the first data packet has stopped, the CGT and / or CGRT is stopped and the first data packet is transmitted. This prevents the data transmission operation from being performed after the timer has exceeded the time, ensures that the user device completes the data transmission in advance, and saves delay. Furthermore, the present disclosure can control the cessation of transmission of the first data packet according to a trigger of the user device or network device, and can implement the selection of a highly reliable resource based on enriching the selection method of the second target uplink resource.
