Detailed Description

The following description of the technical solutions according to the embodiments of the present invention will be given with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

The following description will be given of the related art, and terms, according to the embodiments of the present invention, as follows:

1. background on Ultra-reliable and Low Latency Communications, URLLC related low latency communications the demand in 5G radio access networks (Radio Access Network, RAN) 2URLLC supports industrial automation (Factory automation), transmission automation (Transport Industry), transmission of intelligent power (Electrical Power Distribution) and other traffic in 5G systems. In order to support transmission of URLLC service, configuration Grant (CG) is enhanced, i.e. a plurality of CG configurations are introduced, and specific configuration and use of CG (e.g. supporting slot-level (slot-level) period, supporting automatic transmission of CG, etc.) are enhanced. R17 needs to consider supporting URLLC traffic in a new generation (communication system) unlicensed (New Radio Unlicensed, NRU) scenario with interference control. In particular, the manner of use of NRU CG and ul rrc CG enhancements in NRU scenarios may be considered (Harmonizing UL configured-grant enhancements in NRU and URLLC introduced in Rel-16-to be applicable for unlicensed spectrum).

2. CG enhancement in URLLC

In order to support the high delay requirement of URLLC service, the URLLC enhances CG period and supports the service period of any slot-level.

To support the high latency requirements of multiple URLLC services and URLLC services, URLLC incorporates multiple (multiple) CGs. Hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) processes for different CG configurations are different, and the process for different CGs is guaranteed to be different by HARQ-ProcID-Offset 2.

Due to the existence of CG resources and other resource conflicts, automatic transmission for CG is introduced in order to ensure that already packetized media access control protocol data units (Medium Access Control Protocol Data Unit, MAC PDU) (i.e. Deprioritized MAC PDU) in CG resources are not discarded/transmitted as soon as possible. For CG of the packet MAC PDU, which cannot be transmitted due to resource collision, a new transmission may be performed using CG resources in the same CG configuration of the subsequent same HARQ process. The use of automatic transmission is determined by autonomosutx.

3. NRU-related background

The NR operates in an unlicensed band and may include several operating scenarios:

scene a: a carrier aggregation scene, in which a Primary Cell (PCell) is a licensed spectrum, and Secondary cells (scells) working on an unlicensed spectrum are aggregated by a carrier aggregation mode; scene B: in a dual connection operating scenario, PCell is a long term evolution (Long Term Evolution, LTE) licensed spectrum, and PScell is an NR unlicensed spectrum; scene C: an independent working scenario, where NR works as an independent cell in unlicensed spectrum; scene D: NR single cell scene, uplink (UL) works in authorized spectrum, downlink (DL) works in unlicensed spectrum; scene E: in a dual connection working scenario, PCell is NR licensed spectrum, and PScell is NR unlicensed spectrum.

In general, the operating Band (Band) of NRU is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. On unlicensed spectrum, NRU should be designed to ensure fairness with other systems already operating on these unlicensed spectrum, such as wireless fidelity (Wireless Fidelity, wiFi) and the like. The principle of fairness is that NRU's impact on systems already deployed on unlicensed spectrum (such as WiFi) cannot exceed the impact between these systems.

In order to ensure fair coexistence between systems on unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. A general energy detection mechanism is a listen-before-transmit (Listen before talk, LBT) mechanism, whose basic principle is: a base station or terminal (transmitting end) needs to listen for a period of time as specified before transmitting data on the unlicensed spectrum. If the result of interception indicates that the channel is in an idle state, the transmitting end can transmit data to the receiving end. If the interception result indicates that the channel is in an occupied state, the transmission end needs to intercept the channel again according to a set back-off period, and knows that the channel interception result is in an idle state, and then the transmission end can transmit data to the receiving end.

Currently, four channel access mechanisms (category) are defined in NRU, reference TR 38.889:

category 1: direct transmission mechanism

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

switching gap refers to the Switching time for receiving a transmission, typically no more than 16us;

category 2: LBT mechanism without random back-off

This mechanism means that the time for the UE to listen to the channel is deterministic, typically relatively short, such as 25us;

category 3: LBT mechanism of random back-off (fixed contention window)

In the LBT procedure, the transmitting side randomly goes a random value in the contention window to determine the time to listen to the channel;

category 4: LBT mechanism of random back-off (contention window is not fixed)

In the LBT procedure, the transmission side randomly takes a random value in the contention window to determine the time to listen to the channel, and the contention window is variable.

To sum up, for a terminal device, a base station needs to transmit data to the terminal device within a maximum channel occupation time (maximum channel occupancy time, MCOT), if the base station does not occupy a channel, that is, outside the MCOT time, the terminal device will not receive the scheduling data of the base station to the terminal device.

4. Uplink LBT failure in NRU

For uplink transmission initiated by a User Equipment (UE), there are mainly the following categories:

scheduling request (Scheduling Request, SR): for requesting uplink resources;

physical random access channel (Physical Random Access Channel, PRACH) transmission: due to random access channel (Random Access Channel, RACH) trigger, the UE needs to transmit msg1;

physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission: including upstream data transmission based on configuration grant (configured grant) and upstream data transmission based on dynamic grant (dynamic grant);

physical layer signaling: including Acknowledgement (ACK)/non-acknowledgement (NACK) feedback, channel state indication (Channel Status Indicator, CSI) reporting, etc.;

on the unlicensed band, the UE needs to listen to whether the channel is available with LBT before transmitting SR, PRACH or PUSCH, and if not, i.e. LBT fails, the UE needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, information of LBT failure needs to be notified to the MAC layer.

5. CG enhancement in NRU

For flexible resource selection, the HARQ process of NRU CG is not formulated, but the UE selects itself. For one CG resource, the radio resource control (Radio Resource Control, RRC) configures a set of HARQ processes, from which the UE can select one HARQ process for the current CG transmission. The specifically configured HARQ process interval is determined by HARQ-ProcID-Offset and nrofHARQ-Processes.

To support back-to-back resource allocation, NRU introduced multiple CG. Multiple CG configurations may share HARQ processes.

A configuration grant weight timer (CG-retransmission timer) was introduced to support automatic retransmission of CG resources when the resources cannot be transmitted due to LBT failure. After cg-retransmission timer times out, if the configured grant timer (Configured Grant Timer) does not time out, the corresponding HARQ process may be retransmitted.

CG transmissions may be interrupted by dynamically scheduled DCI and downlink feedback indications (downlink feedback information, DFI). The specific behavior is shown in table 1 below:

TABLE 1

	DFI＝ACK	DFI＝NACK	DFI＝new tx	DFI＝retx	CG timer expires
CG timer	Stop	No impact	Start/Restart	Start/Restart	None
CG retx timer	Stop	Stop	Stop	Stop	Stops

In order to solve the above problems, embodiments of the present invention provide a wireless communication method, a terminal device, and a network device, which can determine behaviors of the terminal device and the network device based on a configuration situation of a CG retransmission timer.

Example two

In the case that CG retx timer is not configured, the UE does not expect the network to send DFI messages; in the case of configuring CG retx timer, the network device may send a DFI message.

The specific implementation flow is as follows:

(1) The network device configures CG resources for the UE, for which may include at least one of:

(1.1) configuring an HARQ process ID pool corresponding to the CG resource. For example, the resource corresponds to HARQ process 1,2,3;

(1.2) configuring a CG timer;

(1.3) configuring CG retx timer.

Alternatively, if CG retx timer is configured, the network device may send DFI to the UE;

alternatively, if the CG retx timer is not configured, the UE does not expect to receive the DFI sent by the network.

(2) The UE receives CG configuration information of the network equipment, and configures and uses corresponding CG resources.

Alternatively, if CG retx timer is configured, the UE expects the network device to send a DFI message. Correspondingly, if the UE receives the DFI, the UE may stop CG retx timer according to the DFI and use R16NRU for automatic retransmission.

Alternatively, if CG retx timer is not configured, the UE does not expect the network to send DFI messages. Accordingly, if the UE receives the DFI, the UE may ignore the DFI indication.

In the second embodiment of the invention, a mode of binding the CG retx timer configuration condition and the DFI is provided, the realization of the UE and the network equipment is simplified, and the problem of uncertain terminal equipment behaviors when the CG retx timer is not configured is avoided.

Example III

If the UE receives the DFI without configuring the CG retx timer, the UE ignores the DFI, or the UE considers the MAC PDU to be acquired and/or performs automatic transmission if the first condition is satisfied.

The specific implementation flow is as follows:

(1) The network device configures CG resources for the UE, and for the CG resources, may specifically include at least one of:

(1.2) configuring a CG timer; (CG retx timer is not configured).

Alternatively, if CG retx timer is configured, the UE stops CG timer according to DFI, and the UE may use the provisions in R16NRU to implement automatic retransmission.

Alternatively, if CG retx timer is not configured, the UE receives DFI, and the UE behavior may be one of the following:

the UE ignores the DFI;

the UE considers the MAC PDU to be acquired and/or performs an automatic transmission (R16 URLLC automatic transmission);

in case the above first condition is fulfilled, the UE considers that the MAC PDU is acquired and/or performs an automatic transmission (R16 URLLC automatic transmission).

In the third embodiment of the present invention, a manner of not binding CG retx timer configuration and DFI is provided, that is, specific behavior of UE when CG retx timer is not configured, but DFI is received is clarified. One is to ignore DFI, so as to simplify UE behavior, and the other is to automatically transmit MAC PDU of corresponding HARQ process to avoid packet loss.

Example IV

If the CG retx timer is not configured, if an LBT failure indication is received from the bottom layer, the resource is considered to be a low priority resource and/or transmission corresponding to the grouped MAC PDU is not executed. Further, in the case that CG retx timer is not configured and autonomosutx is configured, if an LBT failure indication is received from the bottom layer, the resource is considered to be a low priority resource and/or transmission corresponding to a grouped MAC PDU is not performed.

The specific implementation flow is as follows:

(1.2) configuring a CG timer; (CG retx timer is not configured).

(2) And the UE receives CG configuration information of the network, and configures and uses corresponding CG resources.

Optionally, if CG retx timer is configured, if the CG resource group is good, but the LBT failure indication of the bottom layer is received, the HARQ process corresponding to the MAC PDU is set to pending, and retransmission is performed at the next available CG resource position. Optionally, if the CG retx timer is not configured, if the MAC PDU is grouped for the CG resource but the LBT failure indication of the bottom layer is received, the resource (CG) is considered to be a low priority resource and/or transmission corresponding to the grouped MAC PDU is not performed. Further, in the case that CG retx timer is not configured and autonomousTX is configured, if an LBT failure indication is received from the bottom layer, the resource is considered to be a low priority resource and/or transmission corresponding to a grouped MAC PDU is not performed.

Accordingly, at the next available CG resource, the grouped MAC PDU is transmitted (i.e. automatic transmission is performed) using the CG resource

Wherein, the available CG resources are: the high priority resource, the same resource size as the grouped MAC PDU, is configured with autonomousTX, and the grouped MAC PDU transmission is not performed.

In the fourth embodiment of the present invention, a method is provided in which uplink CG (UL CG) resource group packets (MAC PD) cannot be transmitted due to LBT failure, and the subsequent available CG resources are used for automatic transmission, so as to avoid the problem of packet loss after the group.

For example, in the embodiment of the present invention, the terminal device may be a mobile phone, as shown in fig. 6, where the mobile phone may include: radio Frequency (RF) circuitry 610, memory 620, input unit 630, display unit 640, sensor 650, audio circuitry 660, wireless fidelity (wireless fidelity, wiFi) module 670, processor 680, and power supply 690. The radio frequency circuit 610 includes a receiver 611 and a transmitter 612. Those skilled in the art will appreciate that the handset configuration shown in fig. 6 is not limiting of the handset and may include more or fewer components than shown, or may combine certain components, or may be arranged in a different arrangement of components.

The RF circuit 610 may be configured to receive and transmit signals during a message or a call, and in particular, receive downlink information of a base station and process the downlink information with the processor 680; in addition, the data of the design uplink is sent to the base station. Typically, the RF circuitry 610 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (low noise amplifier, LNA), a duplexer, and the like. In addition, the RF circuitry 610 may also communicate with networks and other devices via wireless communications. The wireless communications may use any communication standard or protocol including, but not limited to, global system for mobile communications (global system of mobile communication, GSM), general packet radio service (general packet radio service, GPRS), code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), long term evolution (long term evolution, LTE), email, short message service (short messaging service, SMS), and the like.

The memory 620 may be used to store software programs and modules, and the processor 680 may perform various functional applications and data processing of the cellular phone by executing the software programs and modules stored in the memory 620.

Alternatively, the touch panel 631 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch azimuth of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 680 and can receive commands from the processor 680 and execute them. In addition, the touch panel 631 may be implemented in various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 630 may include other input devices 632 in addition to the touch panel 631.

Although in fig. 6, the touch panel 631 and the display panel 641 are two independent components to implement the input and input functions of the mobile phone, in some embodiments, the touch panel 631 and the display panel 641 may be integrated to implement the input and output functions of the mobile phone.

Specifically, the light sensor may include an ambient light sensor that may adjust the brightness of the display panel 641 according to the brightness of ambient light, and a proximity sensor that may turn off the display panel 641 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the acceleration in all directions (generally three axes), and can detect the gravity and direction when stationary, and can be used for applications of recognizing the gesture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer gesture calibration), vibration recognition related functions (such as pedometer and knocking), and the like; other sensors such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc. that may also be configured with the handset are not described in detail herein.

Audio circuitry 660, speaker 661, microphone 662 may provide an audio interface between a user and the handset. The audio circuit 660 may transmit the received electrical signal converted from audio data to the speaker 661, and the electrical signal is converted into a sound signal by the speaker 661 to be output; on the other hand, microphone 662 converts the collected sound signals into electrical signals, which are received by audio circuit 660 and converted into audio data, which are processed by audio data output processor 680 for transmission to, for example, another cell phone via RF circuit 610, or which are output to memory 620 for further processing.

WiFi belongs to a short-distance wireless transmission technology, and a mobile phone can help a user to send and receive emails, browse webpages, access streaming media and the like through a WiFi module 670, so that wireless broadband Internet access is provided for the user. Although fig. 6 shows a WiFi module 670, it is understood that it does not belong to the necessary constitution of the mobile phone, and can be omitted entirely as required within the scope of not changing the essence of the invention.

Processor 680 is a control center of the handset, connects various parts of the entire handset using various interfaces and lines, and performs various functions and processes of the handset by running or executing software programs and/or modules stored in memory 620, and invoking data stored in memory 620, thereby performing overall monitoring of the handset. Optionally, processor 680 may include one or more processing units; preferably, the processor 680 may integrate an application processor that primarily handles operating systems, user interfaces, applications, etc., with a modem processor that primarily handles wireless communications.
