[0024] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] The following is a brief description of some terms involved in the embodiments of the present invention, as shown below:

[0026] 1. Background of Ultra-reliable and Low Latency Communications (URLLC)

[0027] 5G Radio Access Network (RAN) 2URLLC requires support for the transmission of services such as industrial automation (Factory automation), transport automation (Transport Industry), and smart power (Electrical Power Distribution) in the 5G system. In order to support the transmission of URLLC services, the configured grant (CG) is enhanced, that is, multiple CG configurations are introduced, and the specific configuration and use of CG (such as supporting slot-level cycles, supporting automatic transmission of CG, etc.) are enhanced. R17 needs to consider supporting URLLC services in the interference-controlled new generation (communication system) unlicensed (New Radio Unlicensed, NRU) scenario. Specifically, the use of NRU CG and ULRRC CG enhancements can be considered in the NRU scenario. -HarmonizingUL configured-grant enhancements in NRU and URLLC introduced in Rel-16 to be applicable for unlicensed spectrum.

[0028] 2. CG enhancement in URLLC

[0029] To support the high latency requirements of URLLC services, URLLC enhances the CG cycle and supports any slot-level service cycle.

[0030] In order to support multiple URLLC services and high latency requirements of URLLC services, URLLC introduces multiple CGs. Different CGs have different Hybrid Automatic Repeat Request (HARQ) processes, and harq-ProcID-Offset2 is used to ensure that the processes of different CGs are different.

[0031] Due to the conflict between CG resources and other resources, automatic transmission for CG is introduced to ensure that the packaged Media Access Control Protocol Data Unit (MAC PDU) (i.e. Deprioritized MAC PDU) in the CG resources is not discarded / transmitted as soon as possible. For the CG that cannot be transmitted due to resource conflict, the subsequent CG resources in the same HARQ process and the same CG configuration can be used for new transmission. The use of automatic transmission is determined by autonomousTx.

[0032] 3. NRU related background

[0033] NR operates in unlicensed frequency bands and can include the following operating scenarios:

[0034] Scenario A: Carrier aggregation scenario, the primary cell (PCell) is the licensed spectrum, and the secondary cell (SCell) working on the unlicensed spectrum is aggregated through carrier aggregation; Scenario B: Dual connection working scenario, PCell is the Long Term Evolution (LTE) licensed spectrum, and PScell ​​is the NR unlicensed spectrum; Scenario C: Independent working scenario, NR works as an independent cell in the unlicensed spectrum; Scenario D: NR single cell scenario, uplink (UL) works in the licensed spectrum, and downlink (DL) works in the unlicensed spectrum; Scenario E: Dual connection working scenario, PCell is the NR licensed spectrum, and PScell ​​is the NR unlicensed spectrum.

[0035] Generally speaking, the operating frequency bands of NRU are 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. In the unlicensed spectrum, the design of NRU should ensure fairness with other systems that have already worked in these unlicensed spectrums, such as Wireless Fidelity (WiFi). The principle of fairness is that the impact of NRU on systems that have already been deployed in the unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.

[0036] In order to ensure fair coexistence between systems on the unlicensed spectrum, energy detection has been agreed upon as a basic coexistence mechanism. The general energy detection mechanism is the Listen before Talk (LBT) mechanism. The basic principle of this mechanism is that before the base station or terminal (transmitter) transmits data on the unlicensed spectrum, it needs to listen for a period of time as specified. If the listening result indicates that the channel is idle, the transmitter can transmit data to the receiver. If the listening result indicates that the channel is occupied, the transmitter needs to back off for a period of time according to the regulations and continue to listen to the channel until the channel listening result shows that it is idle before transmitting data to the receiver.

[0037] Currently, four channel access mechanisms (category) are defined in NRU, refer to TR 38.889:

[0038] Category 1: Direct transmission mechanism:

[0039] This mechanism is used for the TX side to transmit quickly after the switching gap within the channel occupancy time (COT);

[0040] Switching gap refers to the conversion time from receiving to transmitting, and the typical value is no more than 16us;

[0041] Category 2: LBT mechanism without random back-off

[0042] This mechanism means that the time for UE to monitor the channel is fixed, usually short, such as 25us;

[0043] Category 3: LBT mechanism with random back-off (fixed contention window)

[0044] In the LBT process, the transmission side randomly selects a random value in the contention window to determine the time to listen to the channel;

[0045] Category 4: LBT mechanism with random back-off (contention window is not fixed)

[0046] In the LBT process, the transmission side randomly takes a random value in the contention window to determine the time to listen to the channel. The contention window is variable.

[0047] In summary, for terminal devices, the base station needs to transmit data to the terminal device within the maximum channel occupancy time (MCOT). If the base station does not seize the channel, that is, outside the MCOT time, the terminal device will not receive the scheduling data from the base station to the terminal device.

[0048] 4. Uplink LBT failure in NRU

[0049] Uplink transmission initiated by User Equipment (UE) mainly includes the following categories:

[0050] Scheduling Request (SR): used to request uplink resources;

[0051] Physical Random Access Channel (PRACH) transmission: Due to the triggering of Random Access Channel (RACH), UE needs to send msg1;

[0052] Physical Uplink Shared Channel (PUSCH) transmission: including uplink data transmission based on configured grant and uplink data transmission based on dynamic grant;

[0053] Physical layer signaling transmission: including Acknowledge (ACK) / NACK (Not Acknowledge) feedback, Channel Status Indicator (CSI) reporting, etc.

[0054] On unlicensed bands, before transmitting SR, PRACH or PUSCH, UE needs to use LBT to detect whether the channel is available. If it is not available, that is, LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the MAC layer needs to be notified of the LBT failure.

[0055] 5. CG Enhancement in NRU

[0056] For flexible resource selection, the HARQ process of NRU CG is not calculated according to the formula, but selected by the UE itself. For a CG resource, the Radio Resource Control (RRC) configures a HARQ process set, and the UE can select a HARQ process from the set for this CG transmission. The specific configured HARQ process interval is determined by harq-ProcID-Offset and nrofHARQ-Processes.

[0057] To support back-to-back resource configuration, NRU introduces multiple CGs. Multiple CG configurations can share the HARQ process.

[0058] The configuration grant retransmission timer (cg-RetransmissionTimer) is introduced to support automatic retransmission of resources when CG resources cannot be transmitted due to LBT failure. After the cg-RetransmissionTimer times out, if the configuration grant timer (Configured Grant Timer) has not timed out, the corresponding HARQ process can be retransmitted.

[0059] CG transmission can be interrupted by dynamic scheduling DCI and downlink feedback information (DFI). The specific behavior is shown in Table 1 below:

[0060]

[0061]

[0062] Table 1

[0063] It is undetermined how R17 supports URLLC service transmission using CG resources in NRU interference controlled scenarios, interference uncontrolled scenarios, or partially interference controlled scenarios.

[0139] The triggered SR and the packaged MAC PDU are indicated to the physical layer.

[0140] Implementation method 2: Enhanced usage or configuration method of CG resources corresponding to enhanced URLLC

[0141] Optionally, the method further comprises at least one of the following:

[0142] The CG resource configuration information does not include configuration information of the second timer;

[0143] The terminal device does not start or maintain the second timer;

[0144] The terminal device acquires the second HARQ process by adopting a UE-determined or self-selected manner; exemplarily, the CG position HARQ process under the target CG configuration can be selected by itself.

[0145] The terminal device automatically transmits the second HARQ process, or automatically retransmits the second HARQ process using a second transmission mechanism; optionally, the identifier of the CG resource for transmitting the second HARQ process is the same, or the identifier of the CG resource for transmitting the second HARQ process is different, or the identifier of the CG resource for transmitting the second HARQ process is different and the transport block size (Transport Block Size, TBS) is the same. That is, the same CG resource or different CG resources can be used to automatically retransmit the second HARQ process. Optionally, the CG resource here can be a CG resource corresponding to URLLC or a CG resource corresponding to NRU.

[0146] Exemplarily, for automatic retransmission, autonomousTX transmission is used, and any CG position can be used for transmission, as long as this position selects this HARQ process. If different CG HARQ processes can share the HARQ process, other CGs can also be used. Optionally, other CGs must have the same TBS (either auto resource selection screen or gNB configuration screen). When the first environment is a controlled environment, there is no need to consider LBT failure because the interference is controlled, so there is no pending caused by LBT failure. Downlink LBT failure causes DCI / DFI to fail to come down and requires CG retx timer to trigger retransmission and other problems.

[0147] The terminal device configures the offset of the second HARQ process; or, the terminal device configures the offset 2 of the second HARQ process; optionally, the offset of the HARQ process is the same or different between different CG resources, and the offset2 of the HARQ process is different. Follow NRU, because the process is self-selected, the HARQ process conflict is slightly avoided.

[0148] When the terminal device transmits the CG resource, or when transmitting data of the second HARQ process, the terminal device carries the second UCI, where the second UCI includes at least the second HARQ process;

[0149] The terminal device does not receive or does not expect to receive the second DFI;

[0150] The terminal device receives the second DFI and ignores the second DFI, that is, does not follow the DFI;

[0151] The terminal device receives the second DFI and performs a corresponding operation according to the second DFI, that is, follow DFI;

[0152] The terminal device supports or uses a transmission mode across time slot boundaries; exemplarily, because the allocated resources are fragmented or insufficient to support the required number of transmissions, cross-slot-boundary is supported.

[0153] The terminal device assembles a MAC PDU for each conflicting resource;

[0154] indicating the grouped MAC PDUs to the physical layer; and,

[0155] The triggered SR and the packaged MAC PDU are indicated to the physical layer.

[0156] Exemplarily, for conflicting resources, each resource is packaged into a MAC PDU, or the packaged MAC PDUs are all indicated to the physical layer, or the packaged MAC PDUs and the triggered SR are all indicated to the physical layer (URLLC enhancement, but not necessarily required, and there is no interference when the first environment is a controlled environment).

[0157] 2. CG resources corresponding to NRU

[0158] Implementation 3: CG resource usage or configuration corresponding to legacy NRU

[0159] 1) Uplink LBT failure in NRU

[0160] Uplink transmission initiated by User Equipment (UE) mainly includes the following categories:

[0161] Scheduling Request (SR): used to request uplink resources;

[0162] Physical Random Access Channel (PRACH) transmission: Due to the triggering of Random Access Channel (RACH), UE needs to send msg1;

[0163] Physical Uplink Shared Channel (PUSCH) transmission: including uplink data transmission based on configured grant and uplink data transmission based on dynamic grant;

[0164] Physical layer signaling transmission: including Acknowledge (ACK) / NACK (Not Acknowledge) feedback, Channel Status Indicator (CSI) reporting, etc.

[0165] On unlicensed bands, before transmitting SR, PRACH or PUSCH, UE needs to use LBT to detect whether the channel is available. If it is not available, that is, LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the MAC layer needs to be notified of the LBT failure.

[0166] 2) CG enhancement in NRU

[0167] For flexible resource selection, the HARQ process of NRU CG is not calculated according to the formula, but selected by the UE itself. For a CG resource, the Radio Resource Control (RRC) configures a HARQ process set, and the UE can select a HARQ process from the set for this CG transmission. The specific configured HARQ process interval is determined by harq-ProcID-Offset and nrofHARQ-Processes.

[0168] To support back-to-back resource configuration, NRU introduces multiple CGs. Multiple CG configurations can share the HARQ process.

[0169] The configuration grant retransmission timer (cg-RetransmissionTimer) is introduced to support automatic retransmission of resources when CG resources cannot be transmitted due to LBT failure. After the cg-RetransmissionTimer times out, if the configuration grant timer (Configured Grant Timer) has not timed out, the corresponding HARQ process can be retransmitted.

[0170] CG transmission can be interrupted by dynamic scheduling DCI and downlink feedback information (DFI). The specific behavior is shown in Table 1 above and will not be repeated here.

[0176] The terminal device automatically transmits / retransmits the third HARQ process, or uses the first transmission mechanism to automatically transmit / retransmit the third HARQ process; exemplarily, autonomousTX transmission is used for automatic retransmission. (When the first environment is a controlled environment, there is no need to consider LBT failure, because interference is controlled, so there is no pending caused by LBT failure, and downlink LBT failure causes DCI / DFI to fail to come down and requires CG retx timer to trigger retransmission and other issues).

[0177] When the terminal device performs transmission or automatic transmission on the low-priority MAC PDU / low-priority resources, or on the third HARQ process, it does not set or modify the pending state of the third HARQ process, and / or does not restart or start the timer; exemplarily, when resources are transmitted, it is not necessary to modify the pending state of the third HARQ process, and / or the CG retx timer is not started.

[0178] The terminal device configures the offset of the third HARQ process; or, the terminal device configures the offset 2 of the third HARQ process; optionally, the offset of the HARQ process is the same or different between different CG resources, and the offset2 of the HARQ process is different. follow NRU, because the process is self-selected, the HARQ process conflict is slightly avoided.

[0188] Implementation method 5: Corresponding to the enhanced NRU CG resource usage or configuration method (supporting URLLC)

[0189] Optionally, the method further comprises at least one of the following:

In an available CG, the pending HARQ process is transmitted. (When the first environment is a controlled environment, there is no need to consider LBT failure because the interference is controlled, so there is no pending caused by LBT failure. Downlink LBT failure causes DCI / DFI to fail to come down and requires CG retx timer and other triggering retransmissions.)

The terminal device of the embodiment of the present application can implement any one of the implementation modes of the above method. Figure 6 As shown, it is a schematic diagram of another embodiment of a terminal device in an embodiment of the present invention. The terminal device is described by taking a mobile phone as an example, and may include: a radio frequency (RF) circuit 610, a memory 620, an input unit 630, a display unit 640, a sensor 650, an audio circuit 660, a wireless fidelity (WiFi) module 670, a processor 680, and a power supply 690. Among them, the RF circuit 610 includes a receiver 614 and a transmitter 612. Those skilled in the art can understand that Figure 6 The mobile phone structure shown in the figure does not constitute a limitation on the mobile phone, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0295] Combine the following Figure 6 A detailed introduction to the various components of the mobile phone:

[0296] The RF circuit 610 can be used for receiving and sending signals during information transmission or calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 680 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 610 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 610 can also communicate with the network and other devices through wireless communication. The above wireless communication can use any communication standard or protocol, including but not limited to the global system of mobile communication (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), long term evolution (LTE), email, short messaging service (SMS), etc.

[0297] The memory 620 can be used to store software programs and modules. The processor 680 executes various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory 620. The memory 620 can mainly include a program storage area and a data storage area, wherein the program storage area can store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc.; the data storage area can store data created according to the use of the mobile phone (such as audio data, a phone book, etc.), etc. In addition, the memory 620 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage devices.

[0298] The input unit 630 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile phone. Specifically, the input unit 630 may include a touch panel 631 and other input devices 632. The touch panel 631, also known as a touch screen, can collect the user's touch operation on or near it (such as the user's operation on the touch panel 631 or near the touch panel 631 using any suitable object or accessory such as a finger, stylus, etc.), and drive the corresponding connection device according to a pre-set program. Optionally, the touch panel 631 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into contact coordinates, and then sends it to the processor 680, and can receive and execute commands sent by the processor 680. In addition, the touch panel 631 can be implemented in various types such as resistive, capacitive, infrared, and surface acoustic waves. In addition to the touch panel 631, the input unit 630 may also include other input devices 632. Specifically, the other input devices 632 may include but are not limited to one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, etc.

The display unit 640 may include a display panel 641. Optionally, the display panel 641 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch panel 631 may cover the display panel 641. When the touch panel 631 detects a touch operation on or near it, it is transmitted to the processor 680 to determine the type of touch event. Subsequently, the processor 680 provides a corresponding visual output on the display panel 641 according to the type of touch event. Although in Figure 6 In the embodiment, the touch panel 631 and the display panel 641 are used as two independent components to realize the input and output functions of the mobile phone, but in some embodiments, the touch panel 631 and the display panel 641 can be integrated to realize the input and output functions of the mobile phone.

[0300] The mobile phone may also include at least one sensor 650, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 641 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 641 and / or the backlight when the mobile phone is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that can be configured in the mobile phone, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be repeated here.

[0301] The audio circuit 660, the speaker 661, and the microphone 662 can provide an audio interface between the user and the mobile phone. The audio circuit 660 can transmit the received audio data to the speaker 661 after converting the received audio data into an electrical signal, which is converted into a sound signal for output; on the other hand, the microphone 662 converts the collected sound signal into an electrical signal, which is received by the audio circuit 660 and converted into audio data, and then the audio data is output to the processor 680 for processing, and then sent to another mobile phone through the RF circuit 610, or the audio data is output to the memory 620 for further processing.

[0302] WiFi is a short-range wireless transmission technology. The mobile phone can help users send and receive emails, browse web pages and access streaming media through the WiFi module 670. It provides users with wireless broadband Internet access. Figure 6 A WiFi module 670 is shown, but it is understandable that it is not an essential component of the mobile phone and can be omitted as needed without changing the essence of the invention.

[0303] The processor 680 is the control center of the mobile phone. It uses various interfaces and lines to connect various parts of the entire mobile phone. By running or executing software programs and / or modules stored in the memory 620, and calling data stored in the memory 620, it executes various functions of the mobile phone and processes data, thereby monitoring the mobile phone as a whole. Optionally, the processor 680 may include one or more processing units; preferably, the processor 680 may integrate an application processor and a modem processor, wherein the application processor mainly processes the operating system, user interface, and application programs, and the modem processor mainly processes wireless communications. It is understandable that the above-mentioned modem processor may not be integrated into the processor 680.

[0304] The mobile phone also includes a power supply 690 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 680 through a power management system, so that the power management system can manage charging, discharging, power consumption management, etc. Although not shown, the mobile phone can also include a camera, a Bluetooth module, etc., which will not be described in detail here.
