The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0053] It should be understood that the "indication" mentioned in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0054] In the description of the embodiments of the present application, the term "corresponding" may indicate a direct or indirect correspondence between two items, or an association relationship between the two items, or a relationship between indication and being indicated, configuration and being configured, and the like.

[0055] The fifth generation mobile communication technology (5-Generation, 5G) radio access network (Radio Access Network, RAN) 2URLLC requires support for the transmission of industrial automation (Factory automation), transmission automation (TransportIndustry), smart power (Electrical Power Distribution) and other services in the 5G system. In order to support the transmission of URLLC services, the 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.

[0056] Release 17 (R17) needs to consider supporting URLLC services in interference-controlled NR-U scenarios. Specifically, the enhanced use of NR-U CG and ULRRC CG in NR-U scenarios can be considered.

[0057] To support the high latency requirements of URLLC services, URLLC enhances the CG cycle and supports any slot-level service cycle.

[0058] 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 the harq-ProcID-Offset2 field is used to ensure that the processes of different CGs are different.

[0059] Due to the conflict between CG resources and other resources, automatic transmission for CG is introduced to ensure that the Media Access Control Protocol Data Unit (MAC PDU) (i.e., non-prioritized MAC PDU) that has been packaged 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 the automatic transmission (autonomousTx) field.

[0060] It should be noted that NR-U includes the following working scenarios:

[0061] Scenario A: Carrier aggregation scenario, the primary cell (PCell) is the licensed spectrum, and the secondary cells (SCell) working on the unlicensed spectrum are aggregated through carrier aggregation;

[0062] Scenario B: Dual-connectivity working scenario, PCell is LTE licensed spectrum, and Primary Secondary Cell (PSCell) is NR unlicensed spectrum;

[0063] Scenario C: Independent working scenario, NR works as an independent cell in unlicensed spectrum;

[0064] Scenario D: NR single-cell scenario, the uplink (UL) works in the licensed spectrum and the downlink (DL) works in the unlicensed spectrum;

[0065] Scenario E: Dual-connectivity working scenario, PCell is NR licensed spectrum, and PScell ​​is NR unlicensed spectrum.

[0066] Generally speaking, the operating frequency bands of NR-U are 5GHz unlicensed spectrum and 6GHz unlicensed spectrum. In the unlicensed spectrum, the design of NR-U should ensure fairness with other systems that have already worked in these unlicensed spectrums, such as Wireless Fidelity (Wi-Fi). The principle of fairness is that the impact of NR-U on systems that have already been deployed in the unlicensed spectrum (such as Wi-Fi) cannot exceed the impact between these systems.

[0067] 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.

[0068] The following four channel access mechanisms (category) are defined in NR-U.

[0069] Category 1: Direct transmission mechanism:

[0070] This mechanism is used by the transmit (TX) side to quickly transmit after the switching gap within the channel occupancy time (COT);

[0071] Switching gap refers to the conversion time from receiving to transmitting, and the typical value is no more than 16us.

[0072] Category 2: LBT mechanism without random back-off:

[0073] This mechanism means that the time that the terminal device listens to the channel is fixed, usually short, such as 25us.

[0074] Category 3: LBT mechanism with random back-off (fixed contention window):

[0075] 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.

[0076] Category 4: LBT mechanism with random back-off (contention window is not fixed):

[0077] 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.

[0078] In summary, for the terminal, the base station needs to transmit data to the terminal within the maximum channel occupancy time (MCOT). If the base station does not seize the channel, that is, outside the MCOT time, the terminal will not receive the scheduling data from the base station to the terminal.

[0079] For uplink transmission initiated by terminal devices, there are mainly the following categories:

[0080] Scheduling request (SR): used to request uplink resources;

[0081] Physical Random Access Channel (PRACH) transmission: Due to the triggering of the Random Access Channel (RACH), the terminal device needs to send the first message (message 1, Msg 1) in the four-step random access;

[0082] Physical Uplink Shared Channel (PUSCH) transmission: including CG-based uplink data transmission and dynamic grant-based uplink data transmission;

[0083] Physical layer signaling transmission: including Acknowledgement (ACK) / Negative Acknowledgement (NACK) feedback, Channel State Information (CSI) reporting, etc.

[0084] On unlicensed bands, before transmitting SR, PRACH or PUSCH, the terminal device needs to use LBT to monitor whether the channel is available. If it is not available, that is, LBT fails, the terminal device needs to wait until the next transmission opportunity to perform LBT again. If LBT failure is detected, the media access control (MAC) layer needs to be notified of the LBT failure.

[0085] For flexible resource selection, the HARQ process of NR-U CG is not calculated according to the formula, but is selected by the terminal device itself. For a CG resource, the Radio Resource Control (RRC) configures a HARQ process set, and the terminal device can select a HARQ process from the set for this CG transmission. The specific configured HARQ process interval is determined by the harq-ProcID-Offset field and the nrofHARQ-Processes field.

[0086] NR-U introduces multiple CGs. Multiple CG configurations can share the HARQ process.

[0087] The CG retransmission timer (CG retx Timer) 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 CG timer (CG Timer) has not timed out, the corresponding HARQ process can be retransmitted.

[0088] CG transmission can be interrupted by dynamic scheduling of downlink control information (Downlink Control Information, DCI) and downlink feedback information (Downlink Feedback Information, DFI), as shown in Table 1 below.

[0089] Table 1

[0090]

[0091] It should be noted that, in the above Table 1, DFI=ACK means that DFI indicates ACK, DFI=NACK means that DFI indicates NACK, DCI=new transmission means that DCI indicates new transmission, and DCI=retransmission means that DCI indicates retransmission.

[0092] In order to support URLLC services in interference-controlled NR-U scenarios, the CG scheduling method is enhanced and NR-U CG resources and ULRRC CG resources are introduced. However, how to reasonably use NR-U CG resources and ULRRC CG resources, and how to use DFI by terminal devices in scenarios where NR-U CG resources and ULRRC CG resources coexist, is still an urgent problem to be solved.

[0093] Based on the above problems, this application proposes a solution for using CG resources. When receiving DFI, for URLLC CG resources, the terminal device ignores DFI; and / or, for NR-U CG resources, the terminal device uses DFI. Thus, in the scenario where NR-U CG resources and ULLRRC CG resources coexist, the terminal device can reasonably use DFI to improve communication performance.

[0094] The technical solution of the present application is described in detail below through specific embodiments.

[0096] S210, when receiving DFI,

[0097] For the first type of CG resources, the terminal device ignores the DFI; and / or,

[0098] For the second type of CG resources, the terminal device uses the DFI.

[0102] Of course, the first type of CG resources may also be other types of CG resources, and the second type of CG resources may also be other types of CG resources, which is not limited in the embodiments of the present application.

[0103] In the embodiment of the present application, the use of DFI by the terminal device can be understood as: the terminal device can transmit on the NR-U CG resource based on the DFI indication; or, the terminal device can use the NR-U CG resource for transmission based on the DFI indication. For example, as described in Table 1 above, based on the DFI indication, the CG Timer and the CG retx Timer will respond accordingly to control the transmission on the NR-U CG resource.
