It should be understood that the terms "system" and "network" are used interchangeably herein. The term "and/or" is herein merely an association relationship describing an associated object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

The terminology used in the description section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application. The terms "first," "second," "third," and "fourth" and the like in the description and in the claims of this application and in the drawings, are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion.

In this embodiment of the present application, the "protocol" may refer to a standard protocol in the communication field, for example, may include an LTE protocol, an NR protocol, and related protocols applied in a future communication system, which is not limited in this application.

To facilitate a better understanding of embodiments of the present application, high reliability low latency communications (Ultra-Reliable and Low Latency Communication, URLLC) are described in connection with the present application.

The requirements in URLLC support the transmission of traffic in 5G systems, such as industrial automation (Factory automation), transmission automation (Transport Industry), intelligent power (Electrical Power Distribution), etc. In order to support transmission of URLLC traffic, configuration Grant (CG) is enhanced, i.e. a plurality of CG configurations are introduced, and specific configuration and use of CG (e.g. a period supporting slot-level, supporting automatic transmission of CG, etc.) are enhanced.

Release17 (R17) needs to consider supporting URLLC traffic in interference controlled NR-U scenarios. In particular, the manner of use of NR-U CG and ul rrc CG enhancements in NR-U scenarios may be considered, as well as the initial channel occupation time (channel occupancy time, COT) of the frame-based device (Frame Based Equipment, FBE).

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 difference for different CGs is guaranteed by HARQ process number Offset (HARQ-ProcID-Offset 2).

Due to the existence of CG resources and other resource conflicts, in order to ensure that media access control protocol data units (Media Access Control Protocol Data Unit, MAC PDUs) already packetized in CG resources (i.e. non-prioritized MAC PDUs) are not discarded/transmitted as soon as possible, automatic transmission for CG is introduced. 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 automatic transmission (autonomosutx).

If the physical layer priorities are different: with CG and CG collisions, the medium access control (Media Access Control, MAC) layer may instruct the physical layer of one or more MAC PDUs. Similarly, if there is a collision of data (data) and scheduling request (Scheduling Request, SR), the MAC layer may also instruct SR and MAC PDU to the physical layer.

For a better understanding of the embodiments of the present application, NR-U relevant to the present application will be described.

NR-U includes 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 working scenario, the PCell is an LTE licensed spectrum, and the primary and secondary cells (Primary Secondary Cell, PSCell) are NR unlicensed spectrums;

scene C: an independent working scenario, where NR works as an independent cell in unlicensed spectrum;

scene D: an NR single cell scenario, with Uplink (UL) operating in licensed spectrum and Downlink (DL) operating in unlicensed spectrum;

scene E: in a dual connection working scenario, PCell is NR licensed spectrum, and PScell is NR unlicensed spectrum.

Generally, the operating 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 operating on these unlicensed spectrum, such as WiFi, etc. The principle of fairness is that the NR-U cannot have more impact on systems already deployed on unlicensed spectrum (such as WiFi) than 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.

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

category 1, direct transport mechanism:

this mechanism is used on the Transmit (TX) side to transmit quickly 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 of random back-off is not needed:

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 (contention window fixed):

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 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, a base station needs to transmit data to the terminal within a maximum channel occupation time (maximum channel occupancy time, MCOT), if the base station does not preempt a channel, that is, outside the MCOT time, the terminal will not receive the scheduling data from the base station to the terminal.

In NR-U, for uplink transmission initiated by a terminal device, 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 the random access trigger, the terminal device needs to send the first information (Message 1, msg 1) in the four-step random access or the first information (Message a, msg a) in the two-step random access;

Physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission: including upstream data transmission based on a Configuration Grant (CG) and upstream data transmission based on a Dynamic Grant (DG);

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

on the unlicensed band, the terminal device 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 terminal device needs to wait until the next transmission opportunity to perform LBT again. If an LBT failure is detected, information indicating the LBT failure is required for the medium access control (Media Access Control, MAC) layer.

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

The high priority resources are preferentially used for transmission when resource collision occurs. However, in some scenarios, such as when the terminal device works or accesses to an unlicensed frequency band, the LBT is not necessarily successful for the high-priority resource, and in this case, the high-priority resource cannot be transmitted, which causes resource waste.

Based on the above problems, the present application proposes a resource usage scheme, which uses available resources to transmit as much as possible when resource collision occurs, so as to avoid resource waste.

and the terminal equipment reorganizes the MAC PDU corresponding to the second resource, and transmits the MAC PDU aiming at the second resource reorganization packet by using the first resource under the condition that the LBT detection of the first resource is successful.

In this case, the first condition may specifically be:

or alternatively, the process may be performed,

Alternatively, the scheme of example 1 is applicable to terminal devices operating or accessing unlicensed bands.

Therefore, when resources conflict on an unlicensed frequency band, the low-priority resources can be packaged and transmitted, the available resources can be utilized as much as possible for transmission, and the problem of resource waste caused by no resource transmissibility due to LBT failure is avoided.

For example, as shown in FIG. 3, there is a resource conflict between grant resource 1 and grant resource 2, and grant resource 2 has a lower priority than grant resource 1. Authorized resource 1: high priority, but LBT failed; the terminal device packs the grant resource 1, but the detection of the LBT of the grant resource 1 fails, and the MAC PDU for the packet of the grant resource 1 cannot be sent. Authorized resource 2: the priority is low; the terminal equipment packs the authorized resource 2, after the authorized resource 2 LBT is successful, the terminal equipment uses the authorized resource 2 to transmit the MAC PDU for the authorized resource 2 pack, and if the authorized resource 2 LBT fails, the MAC PDU for the authorized resource 2 pack cannot be transmitted.

As another example, as shown in fig. 4, there is a resource conflict between grant resource 1 and grant resource 2, and the priority of grant resource 2 is lower than that of grant resource 1. Authorized resource 1: high priority, but LBT failed; the terminal device packs the grant resource 1, but the detection of the LBT of the grant resource 1 fails, and the MAC PDU for the packet of the grant resource 1 cannot be sent. Authorized resource 2: the priority is low; since grant 1 and grant 2 share HARQ processes, after grant 2 LBT is successful, the terminal device may use grant 2 to transmit MAC PDUs for grant 1 group packets, and if grant 2 LBT fails, the MAC PDUs for grant 1 group packets cannot be sent.

As another example, as shown in fig. 5, there is a resource conflict between grant resource 1 and grant resource 2, and grant resource 2 has a lower priority than grant resource 1.

Optionally, in example 2, the information for the second resource includes, but is not limited to, at least one of:

Alternatively, the scenario of example 2 is applicable to the terminal device operating or accessing licensed bands.

For example, as shown in FIG. 6, there is a resource conflict between grant resource 1 and grant resource 2, and grant resource 2 has a lower priority than grant resource 1. Authorized resource 1: the priority is high, and the authorized resource 1 comprises a group of resources, wherein the repeated resource 1 LBT fails, the repeated resource 2 LBT fails, and the repeated resource 3 LBT also fails; the terminal device packs the grant resource 1, but the LBT detection of each repeated resource in the set of resources included in the grant resource 1 fails, and the terminal device does not use the grant resource 1 to transmit the MAC PDU for the grant resource 1 pack. Authorized resource 2: the priority is low; the Transport Block Size (TBS) of grant resource 2 is different from the Transport Block Size (TBS) of grant resource 1, and therefore, the terminal device does not group grant resource 2 nor transmit using grant resource 2.

As another example, as shown in fig. 7, there is a resource conflict between grant resource 1 and grant resource 2, and the priority of grant resource 2 is lower than that of grant resource 1. Authorized resource 1: the priority is high, and the authorized resource 1 comprises a group of resources, wherein the repeated resource 1 LBT fails, the repeated resource 2 LBT fails, and the repeated resource 3 LBT also fails; the terminal device packs the grant resource 1, but the LBT detection of each repeated resource in the set of resources included in the grant resource 1 fails, and the terminal device does not use the grant resource 1 to transmit the MAC PDU for the grant resource 1 pack. Authorized resource 2: the priority is low, and the authorized resource 2 comprises a group of resources, wherein rv=0 of the repeated resource a and rv=3 of the repeated resource b; after the repetition resource a of the grant resource 2 is at the starting position of the grant resource 1, and rv=0 of the repetition resource a, the terminal device packs the grant resource 2, when the repetition resource a LBT of the grant resource 2 is successful, transmits the MAC PDU for the packet of the grant resource 2, and if the repetition resource a LBT of the grant resource 2 fails, does not transmit the MAC PDU for the packet of the grant resource 2.

It should be noted that, the grant resource 1 in fig. 6 to 7 may be the second resource in the above example 2, and the grant resource 2 may be the first resource in the above example 2.

Therefore, when resources conflict on the authorized frequency band, the low-priority resources can be packaged and transmitted, the available resources can be utilized as much as possible for transmission, and the problem of resource waste caused by no resource transmissibility due to LBT failure is avoided.

Therefore, in the embodiment of the present application, in the case that there is a resource conflict between the first resource and the second resource, the terminal device may group the first resource and/or use the first resource to transmit. That is, when resource collision occurs, the terminal device may pack the low-priority resources and/or use the low-priority resources for transmission, so as to utilize the available resources to transmit as much as possible, thereby avoiding resource waste.
