In order to facilitate a better understanding of the embodiments of the present application, the ultra-reliable and low latency communication (Ultra-Reliable and Low Latency Communication, URLLC) related to the present application is described.

The URLLC needs to support the transmission of services such as Factory automation, Transport Industry, and Electrical Power Distribution in the 5G system. In order to support the transmission of URLLC services, the Configuration Grant (CG) is enhanced, that is, multiple CG configurations are introduced, as well as the specific configuration and use of CGs (such as supporting slot-level period, Support for automatic transfer of CG, etc.) has been enhanced.

Release 17 (Release17, R17) needs to consider supporting the URLLC service in the interference-controlled NR-U scenario. Specifically, in the NR-U scenario, the enhanced usage of NR-UC CG and ULRRC CG can be considered, and the initial channel occupancy time (COT) of Frame Based Equipment (FBE) can be considered.

To support the high latency requirements of URLLC services, URLLC enhances the CG cycle to support any slot-level service cycle.

In order to support multiple URLLC services and high latency requirements of URLLC services, URLLC introduces multiple (multiple) CGs. The hybrid automatic repeat request (HARQ) process of different CG configurations is different, and the process of different CGs is guaranteed to be different through the HARQ process ID offset (harq-ProcID-Offset2).

Due to the conflict between CG resources and other resources, in order to ensure that the media access control protocol data units (Media Access Control Protocol Data Unit, MAC PDU) (ie, non-prioritized (Deprioritized) MAC PDUs) that have been packaged in the CG resources are not used. Discard/transmit as soon as possible, automatic transmission for CG was introduced. For the CG of the group of MAC PDUs that cannot be transmitted due to resource conflict, the subsequent CG resources of the same HARQ process and the same CG configuration can be used for new transmission. The use of automatic transmission is determined by automatic transmission (autonomousTx).

If the priorities of the physical layers are different: there is a conflict between the CG and the CG, the media access control (Media Access Control, MAC) layer may indicate one or more MAC PDUs to the physical layer. Similarly, if there is a conflict between data (data) and scheduling request (Scheduling Request, SR), the MAC layer can also indicate the SR and MAC PDU to the physical layer.

To facilitate a better understanding of the embodiments of the present application, NR-Us related to the present application are described.

NR-U includes the following working scenarios:

Scenario A: Carrier aggregation scenario, the primary cell (Primary Cell, PCell) is the licensed spectrum, and the secondary cells (Secondary Cell, SCell) working on the unlicensed spectrum are aggregated through carrier aggregation;

Scenario B: Dual-connection working scenario, PCell is LTE licensed spectrum, Primary Secondary Cell (PSCell) is NR unlicensed spectrum;

Scenario C: Independent working scenario, NR works as an independent cell in unlicensed spectrum;

Scenario D: NR single-cell scenario, the uplink (Uplink, UL) works in the licensed spectrum, and the downlink (Downlink, DL) works in the unlicensed spectrum;

Scenario E: Dual-connection working scenario, PCell is NR licensed spectrum, PScell is NR unlicensed spectrum.

Generally speaking, the working frequency band (Band) of NR-U is 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. On unlicensed spectrum, the design of NR-U should ensure fairness with other systems already working on these unlicensed spectrum, such as WiFi. The principle of fairness is that NR-U cannot affect systems already deployed on unlicensed spectrum (such as WiFi) more than between those systems.

To ensure fair coexistence among systems on unlicensed spectrum, energy detection has been agreed as a basic coexistence mechanism. The general energy detection mechanism is the Listen Before Talk (LBT) mechanism. The basic principle of this mechanism is: before the base station or terminal (transmitter) transmits data on the unlicensed spectrum, it needs to listen for a period of time according to regulations. time. If the result of listening indicates that the channel is in an idle state, the transmitting end can transmit data to the receiving end. If the listening result indicates that the channel is in an occupied state, the transmitting end needs to roll back for a period of time and continue to listen to the channel according to the regulations. Only when the channel listening result is in an idle state can data be transmitted to the receiving end.

Four channel access mechanisms (category) are currently defined in NR-U:

Category 1, direct transfer mechanism:

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

Switching gap refers to the conversion time when the transmission is received, and the typical value is not more than 16us;

Category 2, LBT mechanism that does not require random back-off:

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

Category 3, LBT mechanism of random back-off (fixed competition window):

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

Category 4, LBT mechanism of random back-off (the competition window is not fixed):

In the LBT process, the transmitting side randomly selects 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 the terminal, the base station needs to transmit data to the terminal within the maximum channel occupancy time (MCOT) time. If the base station does not preempt the channel, that is, outside the MCOT time, the terminal will not. After receiving the scheduling data from the base station to the terminal.

In NR-U, the uplink transmission initiated by terminal equipment mainly includes the following categories:

Scheduling request (SR): used to request uplink resources;

Physical Random Access Channel (PRACH) transmission: Due to the random access trigger, the terminal device needs to send the first message (Message1, Msg 1) in the four-step random access or the first message in the two-step random access. The first message (Message A, Msg A);

Physical Uplink Shared Channel (PUSCH) transmission: including uplink data transmission based on configured grant (CG) and uplink data transmission based on dynamic grant (DG);

Physical layer signaling transmission: including acknowledgement (Acknowledgement, ACK)/negative acknowledgement (Negative Acknowledgement, NACK) feedback, channel state information (Channel State Information, CSI) reporting, etc.;

On the unlicensed frequency band, the terminal device needs to use LBT to monitor whether the channel is available before transmitting SR, PRACH or PUSCH. If it is not available, that is, the LBT fails, the terminal device needs to wait until the next transmission opportunity to perform LBT again. If the LBT failure is detected, the information of the LBT failure needs to be notified to the Media Access Control (Media Access Control, MAC) layer.

In release 16 (release16, R16), it is considered that only one resource that needs to be transmitted is indicated from the MAC layer to the physical layer.

In the event of resource conflict, high-priority resources are preferentially used for transmission. However, in some scenarios, such as when a terminal device works or accesses an unlicensed frequency band, the LBT of high-priority resources may not be successful. In this case, high-priority resources still cannot be transmitted, resulting in a waste of resources.

Based on the above-mentioned problems, the present application proposes a resource usage scheme, when resource conflict occurs, the available resources are used for transmission as much as possible to avoid resource waste.
