Before describing the usage method of the configuration authorization timer provided by the embodiment of the present application in detail, the related communication technology related to the embodiment of the present application is described.

NTN communication technology:

currently, 3GPP is researching NTN communication technology, and NTN generally provides communication services to terrestrial users by adopting a satellite communication manner. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication increases without significant increase in communication distance. And finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into Low Earth Orbit (LEO) satellites, medium Earth Orbit (MEO) satellites, geosynchronous Orbit (Geostationary Earth Orbit, GEO) satellites, high elliptical Orbit (High Elliptical Orbit, HEO) satellites, and the like according to the Orbit heights. LEO and GEO are the main studies at the present stage. In LEO, the low orbit satellite has a height range of 500 km-1500 km, and the corresponding orbit period is about 1.5 hours-2 hours. The signal propagation delay for single hop communications between terminal devices is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the terminal equipment is not high. In GEO, geosynchronous orbit satellites have an orbit height of 35786km and a period of 24 hours around the earth. The signal propagation delay for single hop communications between terminal devices is typically 250ms. In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

5G NR HARQ mechanism:

the 5G NR communication system includes a two-stage retransmission mechanism, i.e., an HARQ mechanism of a MAC layer and an ARQ mechanism of an RLC layer. The retransmission process of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and complemented by the retransmission function of the RLC layer. In addition, the HARQ mechanism of the MAC layer can provide fast data retransmission, and the automatic retransmission request (Automatic Repeat request, ARQ) mechanism of the RLC layer can provide reliable data transmission.

Specifically, HARQ uses Stop-and-Wait Protocol (Stop-and-Wait Protocol) to transmit data. In the stop-and-wait protocol, after the transmitting end transmits a Transport Block (TB), the transmitting end stops waiting for acknowledgement information, and the receiving end uses 1 bit of information to determine whether the TB is positive (ACK) or Negative (NACK). However, the sender stops waiting for acknowledgements after each transmission, resulting in low data throughput. Thus, 5G NR uses multiple parallel HARQ processes. While one HARQ process is waiting for acknowledgement information, the transmitting end may continue to transmit data using another HARQ process. The multiple parallel HARQ processes together form a HARQ entity (entity) and the HARQ entity incorporates a de-equalization protocol allowing continuous transmission of data. In addition, the HARQ processes include an uplink HARQ process and a downlink HARQ process. The uplink HARQ process is aimed at uplink data transmission, and the downlink HARQ process is aimed at downlink data transmission, and the uplink HARQ process and the downlink HARQ process are mutually independent.

The current NR protocol specifies that the terminal device has a respective HARQ entity for each serving cell. Each HARQ entity maintains a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes, and each uplink and downlink carrier supports a maximum of 16 HARQ processes. The network device may indicate the maximum number of HARQ processes to the terminal device through RRC signaling semi-static configuration according to the network deployment scenario. If the network device does not provide the corresponding configuration parameters, the number of HARQ processes supported by each carrier in the downlink is 8, and the maximum number of HARQ processes supported by each carrier in the uplink is 16 all the time. Each HARQ process corresponds to a HARQ process number (ID). For terminal equipment which does not support downlink space division multiplexing, each downlink HARQ process can only process 1 TB at the same time; for terminal devices supporting downlink space division multiplexing, each downlink HARQ process may process 1 or 2 TBs simultaneously. Each uplink HARQ process of the terminal device simultaneously processes 1 TB. HARQ protocols are classified into two types, synchronous (synchronous) and asynchronous (asynchous) in the time domain, and into two types, non-adaptive and adaptive in the frequency domain, whereas in a 5G NR communication system, an asynchronous adaptive HARQ mechanism is used for both uplink and downlink. Wherein asynchronous HARQ means that data retransmission can occur at any time, i.e. the time interval between the retransmission of the same TB and the last transmission is not fixed, i.e. HARQ processes can be used in any order. Synchronous HARQ means that data retransmission occurs at a fixed time, i.e. the time interval between retransmission of the same TB and the last transmission is fixed, i.e. only a certain HARQ process can be used in a certain subframe. Adaptive HARQ means that the frequency domain resources and modulation and coding strategy (Modulation and Coding Scheme, MCS) used for data retransmission can be changed. Non-adaptive HARQ means that data retransmission must use the same frequency domain resources and MCS as the last transmission (data new transmission or last data retransmission).

Configuring upstream grants (Configured Uplink Grant):

to better serve periodic traffic, the concept of pre-configured resources is introduced, downstream called Semi-persistent scheduling (Semi-Persistent Scheduling, SPS) and upstream called configured upstream grant. Wherein, the NR communication system supports the transmission of the following two types of uplink configuration grants: physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission based on a first type of configuration grant (configured grant Type 1) and PUSCH transmission based on a second type of configuration grant (Configured Grant Type 1). In PUSCH transmission based on the grant of the first type of configuration, transmission resources and transmission parameters including time domain resources, frequency domain resources, period of time domain resources, MCS, repetition number, frequency hopping, HARQ process number, and the like are configured by the network RRC. After receiving the RRC configuration, the terminal device may immediately use the configured transmission parameters to perform PUSCH transmission on the configured time-frequency resource. In PUSCH transmission based on the second type of configuration grant, the following method needs to be adopted for resource configuration: first, transmission resources and transmission parameters including a period (periodicity), a repetition number (repK), a frequency hopping, the number of HARQ processes, etc. of time domain resources are configured by the network RRC. Then, a second type of PUSCH transmission based on configuration grant is activated by PDCCH scrambled with a configuration scheduling radio network temporary identity (Configured Scheduling Radio Network Tempory Identity, CS-RNTI), and simultaneously transmission resources including time domain resources, frequency domain resources, MCS, etc. and transmission parameters are configured. When the terminal equipment receives the RRC configuration, the transmission resource and the transmission parameter of the RRC configuration cannot be immediately used for carrying out the PUSCH transmission, and the PUSCH transmission can be carried out only after the corresponding PDCCH activation and configuration are received.

In the case that the network device configures a certain number of HARQ process IDs for configuring uplink grant, since the maximum number of HARQ processes that the terminal device can configure is 16, the terminal device uses these HARQ process IDs to perform uplink transmission on the resources for configuring the uplink grant indication in a polling manner. It is assumed that the HARQ process ID used by the resource configuring the uplink grant indication at time t0 is identical to the HARQ process ID used at time t1, i.e., HARQ ID i. The terminal device packs 1 MAC PDU (Protocol Data Unit ), MAC PDU1, at time t0 and stores MAC PDU1 in the buffer of HARQ ID i. By time t1, since the same HARQ process is used as time t0, the MAC PDU coming at time t1 will overwrite (flush) the MAC PDU1 buffered in HARQ ID i, even though MAC PDU1 has not been successfully transmitted at this time. Therefore, the NR system introduces a configuration grant timer (configurable granttmer) for the HARQ process, and the MAC PDU stored or buffered in the HARQ process cannot be covered until the corresponding configurable granttmer for the HARQ process expires. The maintenance mode of the configurable granttmer comprises the following steps: if the terminal equipment performs uplink transmission on a DCI scheduled resource in the PDCCH, and an HARQ process used for the uplink transmission can be used for configuring uplink authorized transmission, the terminal equipment starts or restarts a configurable GrantTimer corresponding to the HARQ process; if the terminal equipment performs uplink transmission on the resource configured with the uplink authorization indication, the terminal equipment starts or restarts the configurable GrantTimer corresponding to the HARQ process; if the terminal receives the PDCCH indication configured grant Type 2 to activate, the terminal device stops the running configurable GrantTimer.

In a 5G NR communication system, propagation delay of a communication signal is greatly increased. In order to ensure that the signal propagation delay greatly increases the reliability and continuity of the data transmission without increasing the number of hybrid automatic repeat request (Hybrid Automatic Repeat Request, HARQ) processes, the 3GPP organization is currently discussing schemes for turning on or off the HARQ feedback function of the HARQ processes, which may include: the network device may configure whether to turn on the HARQ feedback function; if the HARQ function is turned off, the terminal device may not need to send HARQ feedback for the PDSCH to the network device; in the case of closing the HARQ feedback function, HARQ retransmission may still be supported in order to ensure data transmission reliability; the method can be used for configuring the starting or closing of the HARQ feedback functions based on the terminal equipment or based on the HARQ processes, in the configuration mode based on the terminal equipment, the HARQ feedback functions of all the HARQ processes of the terminal equipment can be configured to be simultaneously in the starting or closing state, and in the configuration mode based on the HARQ processes, the HARQ feedback functions of one part of the HARQ processes can be configured to be in the starting state, and the HARQ feedback functions of the other part of the HARQ processes can be configured to be in the closing state; for the configuration that the HARQ feedback function is turned on or off, both RRC configuration and DCI indication may be used. The RRC signaling may semi-statically configure which HARQ process or processes turn off or turn on the HARQ feedback function, and the DCI may dynamically indicate whether a certain dynamic scheduling turns off or on the HARQ feedback function of which HARQ process.

The NR communication system supports the HARQ mechanism and introduces configurable granttmer of HARQ processes, and the configuration of configurable granttmer is mainly based on Round-Trip Time (RTT) and scheduling delay of signal transmission between the terminal device and the network device. If the NR communication system is to support the switching on or off based on the HARQ feedback function, the time required to wait for the retransmission schedule is not the same for the HARQ process switching off the HARQ function and the HARQ process switching on the HARQ function. In addition, how the HARQ feedback function of turning on or off the HARQ process affects the configuration mode and the usage method of the configuration grant timer corresponding to the HARQ process needs further research.

In view of the above-mentioned problems, the following describes the execution steps of the method for configuring the use of the grant timer from the point of view of the method example, referring to fig. 2. Fig. 2 is a flowchart of a method for configuring an authorization timer according to an embodiment of the present application, where the method includes:

step 210, the terminal device 110 transmits the first data of the uplink HARQ process on the first uplink resource.

In one possible example, terminal device 110 may receive first configuration information from network device 120. The first configuration information includes a first state information configuring a state of an HARQ feedback function of an uplink grant and an uplink HARQ process. Further, the first state information may include that the state of the HARQ feedback function of the uplink HARQ process is an on state, or may include that the state of the HARQ feedback function of the uplink HARQ process is an off state.

Specifically, in the case where the first state information is in the on state, the network device 120 needs to indicate whether to perform new transmission or retransmission when scheduling uplink transmission to the terminal device 110 next time after receiving the PUSCH, where the new transmission represents that the last PUSCH is received as ACK, and the retransmission represents that the last PUSCH is received as NACK. It can be appreciated that after the terminal device 110 transmits data to the network device 120 through PUSCH, the network device 120 needs to decode the data first and then confirm HARQ feedback information of the data. If the HARQ feedback information is a NACK message, the network device needs to retransmit the data through scheduling of the PDCCH, increasing the time required to wait for retransmission scheduling.

Specifically, in the case where the first state information is in the off state, the network device 120 may schedule uplink transmission to the terminal device 110 without waiting for the result of PUSCH decoding. It will be appreciated that after the terminal device 110 transmits data to the network device 120 through PUSCH, the network device 120 may retransmit the data directly through scheduling of PDCCH without decoding the data to confirm HARQ feedback information of the data, which is beneficial to reduce the time required to wait for retransmission scheduling. In addition, in the case of turning off the HARQ feedback function, HARQ retransmission is still supported in order to ensure reliability of data transmission. That is, when data retransmission is required, the state of the HARQ feedback function of the uplink HARQ process may be configured through the network.

Specifically, the first configuration information may include RRC configuration information, which may include uplink HARQ process configuration parameters including the number of uplink HARQ processes, a state of an HARQ feedback function of each uplink HARQ process (on HARQ feedback function or off HARQ feedback function), and the like. The RRC configuration information may include configuration uplink grant parameters including CS-RNTI, the number of uplink HARQ processes reserved for configuration uplink grant, a resource period for configuration uplink grant, and a configurable grant timer corresponding to the uplink HARQ processes. The RRC configuration information may also include relevant parameters for configuring discontinuous reception (Discontinuous Reception, DRX) including a DRX cycle, a duration Timer (onduration Timer), a DRX inactivity Timer (DRX-inactivity Timer), a DRX retransmission Timer (DRX-retransmission Timer), and a DRX HARQ RTT Timer (DRX-HARQ-RTT-Timer). In addition, the RRC configuration information may configure at least one uplink bandwidth Part (BWP) for each serving cell of the terminal device 110, and configure at least one configuration uplink grant for each BWP of the at least one uplink BWP.

For example, the RRC configuration information configures 4 HARQ processes, i.e., HARQ ID 0, HARQ ID 1, HARQ ID 2, and HARQ ID 3, for the terminal device 110, and each HARQ process corresponds to a configurable granttmer. Wherein, the states of the HARQ feedback functions of HARQ ID 0 and HARQ ID 1 are in an off state, and the states of the HARQ feedback functions of HARQ ID 2 and HARQ ID 3 are in an on state. Then, one uplink BWP is configured for the serving cell of the terminal device 110, and 2 configuration uplink grants are configured for the uplink BWP, wherein one configuration uplink grant may use HARQ ID 0 and HARQ ID 1, and the other configuration uplink grant may use HARQ ID 2 and HARQ ID 3.

Further, the first configuration information may be grant configuration information (configured grant configuration) configured by the RRC through higher layer signaling. Parameters in the configured grant configuration include time domain resources, frequency domain resources, a period (periodicity) of the time domain resources, MCS, antenna ports, sounding reference signal (Sounding Reference Signal, SRS) resource indication, demodulation reference signal (DeModulation Reference Signal, DMRS), repetition number (repK), redundancy version (repK-RV) of repetition, frequency hopping, power control, etc., the number of uplink HARQ processes, a state of HARQ feedback function of the uplink HARQ process (on HARQ feedback function or off HARQ feedback function), etc.

In one possible example, the first uplink resource may include a resource configuring an uplink grant indication or a DCI scheduled resource in the PDCCH. It may be appreciated that the terminal device 110 may transmit the first data of the uplink HARQ process on the resource configured with the uplink grant indication, or may transmit the first data of the uplink HARQ process on the resource scheduled by the DCI in the PDCCH. Furthermore, unlike dynamically scheduled resources, terminal device 110 may use the resources indicated by the configured uplink grant for uplink transmissions all the time and periodically until it is reconfigured by the network. That is, the terminal device 110 may perform uplink transmission at the same time-frequency resource location every fixed period.

Specifically, for the terminal device 110 to transmit the first data of the uplink HARQ process on the first uplink resource, it may be understood that the terminal device 110 may newly transmit the first data of the uplink HARQ process on the first uplink resource, or may retransmit the first data of the uplink HARQ process.

Step 220, the terminal device 110 performs a control operation of the configuration grant timer for the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process.

Specifically, in the case where the first uplink resource is a resource scheduled by DCI in the PDCCH, step 220 may be understood as that if the terminal device 110 receives DCI in the PDCCH indicating to schedule uplink primary transmission or retransmission, and the uplink HARQ process used in the current uplink transmission may be used to configure uplink authorized uplink transmission, the terminal device 110 performs a control operation of the configurable grant timer of the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process used in the current uplink transmission.

Specifically, in the case that the first uplink resource is a resource configured with an uplink grant indication, step 220 may be understood that if the terminal device 110 performs uplink transmission on the resource configured with the uplink grant indication, the terminal device 110 performs the control operation of the configurable granttmer of the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process used in the current uplink transmission.

In one possible example, the terminal device 110 performing the control operation of the configuration grant timer for the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process may include the following operations: executing a control operation for the configurable granttmer of the uplink HARQ process in case that the state of the HARQ feedback function of the uplink HARQ process is not changed with respect to the first state information; or, in a case where the state of the HARQ feedback function of the uplink HARQ process is changed with respect to the first state information, performing a control operation for the configurable grant timer of the uplink HARQ process.

Specifically, if the DCI in the PDCCH does not change the HARQ feedback function of the uplink HARQ process in the first configuration information, the terminal device 110 performs a control operation for configurable grant timer of the HARQ process. Or, if the DCI in the PDCCH has changed the HARQ feedback function of the uplink HARQ process in the first configuration information, the terminal device 110 performs a control operation for configurable grant timer of the HARQ process.

It can be seen that the control operation of the configurational grant timer for the uplink HARQ process is performed by determining whether the state of the HARQ feedback function of the uplink HARQ process is changed relative to the first state information of the uplink HARQ process in the first configuration information, which is favorable for implementing the configuration mode and the usage method of the configuration grant timer for the uplink HARQ process according to determining whether the state of the HARQ feedback function of the uplink HARQ process is changed when the NR communication system considers to turn on or off the HARQ feedback function of the uplink HARQ process.

In one possible example, the terminal device 110 performing the control operation of the configuration grant timer for the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process may include the following operations: executing control operation of configurable GrantTimer for the uplink HARQ process under the condition that the first state information is in an on state; or, in case the first state information is in the off state, performing a control operation for configurable granttmer of the uplink HARQ process. It can be understood that whether the HARQ feedback function of the uplink HARQ process configured by the first configuration information is turned on or off performs the control operation for the configurable grant timer of the uplink HARQ process.

It can be seen that the control operation of the configurable granttmer for the uplink HARQ process is performed by whether the HARQ feedback function of the uplink HARQ process configured by the network is turned on or off, which is favorable for implementing the configuration mode and the usage method of the configuration grant timer for the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process configured by the network under the condition that the NR communication system considers the HARQ feedback function of the uplink HARQ process to be turned on or off.

In one possible example, terminal device 110 may receive DCI from network device 120 in a PDCCH in which the uplink HARQ process is scheduled, the DCI in the PDCCH including the first indication information.

The first indication information may be used to indicate that the state of the HARQ feedback function of the uplink HARQ process is second state information, where the second state information is the same as or different from the first state information.

Further, the first indication information may be used to indicate that the state of the HARQ feedback function of the uplink HARQ process is the second state information in the current transmission process of the first data of the uplink HARQ process, or may be used to indicate that the state of the HARQ feedback function of the uplink HARQ process is the second state information in the current transmission process of the first data of the uplink HARQ process and the subsequent transmission process of the uplink HARQ process. It can be understood that, when the state of the HARQ feedback function of the configured uplink HARQ process in the first configuration information needs to be changed, the DCI may change only the state of the HARQ feedback function of the uplink HARQ process in the current transmission of the first data of the uplink HARQ process, or may change the state of the HARQ feedback function of the uplink HARQ process in the current transmission of the first data of the uplink HARQ process and the subsequent transmission. Compared with the transmission of the first data only, one DCI can change the transmission of the first data of the uplink HARQ process and the state of the HARQ feedback function of the uplink HARQ process of the subsequent transmission, which is beneficial to saving the PDCCH resource of the network under the state that the HARQ feedback function of the uplink HARQ process is also required to be changed in the subsequent transmission. In the case of changing only the transmission procedure of the first data at this time, if the network needs to change the state of the HARQ feedback function for multiple transmissions, it is necessary to transmit indication information for changing the state of the HARQ feedback function in multiple DCIs, which also increases PDCCH resource overhead.

Specifically, the current first data transmission in the uplink HARQ process may be understood as a new transmission or retransmission of the first data in the uplink HARQ process on the first uplink resource, and the subsequent transmission in the uplink HARQ process may be understood as a new transmission or retransmission of the first data in the uplink HARQ process and other data after the first data in the uplink HARQ process on the resource scheduled by the network.

For example, first, the network device 120 sends RRC configuration information to the terminal device 110, where the RRC configuration information includes 1 uplink HARQ process and 1 configuration uplink grant, the uplink HARQ process number is HARQ ID 0, and the state of the HARQ feedback function of the HARQ ID 0 is an on state. Next, the terminal device 110 newly transmits the first data on the resource indicated by the configured uplink grant, and the uplink transmission of the first data uses HARQ ID 0. At this time, the state of the HARQ feedback function of HARQ ID 0 is an on state in the initial transmission of the first data. Then, when the terminal device 110 receives the retransmission of the DCI scheduled first data in the PDCCH, the terminal device 110 retransmits the first data on the DCI scheduled resource in the PDCCH. At this time, if the DCI in the PDCCH can only indicate that the state of the HARQ feedback function of HARQ ID 0 is an off state during the current transmission of the first data of HARQ ID 0, the state of the HARQ feedback function indicating HARQ ID 0 is changed to an on state in which RRC signaling is configured when the next retransmission of the first data is also required. If the DCI in the PDCCH may indicate that the state of the HARQ feedback function of HARQ ID 0 is in the off state during the current transmission of the first data and the subsequent transmission of HARQ ID 0, the state of the HARQ feedback function of HARQ ID 0 is still in the off state when the next retransmission of the first data is required.

It can be seen that by considering whether the indication information in one DCI changes the state of the HARQ feedback function of the uplink HARQ process in the current transmission of the uplink HARQ process or in the current transmission and the subsequent transmission of the uplink HARQ process, the DCI function in the PDCCH is further extended, so as to meet the needs of different communication scenarios in the 5G NR communication system. In addition, considering whether the indication information in one DCI indicates to change the state of the HARQ feedback function of the uplink HARQ process in the current transmission and the subsequent transmission of the uplink HARQ process is also beneficial to saving the overhead of PDCCH resources.

Further, the terminal device 110 performing the control operation of the configuration grant timer for the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process may include the following operations: and executing control operation of the configuration grant timer for the uplink HARQ process according to the first state information and the second state information. It can be understood that whether to change the state of the HARQ feedback function of the uplink HARQ process is indicated by DCI in the PDCCH to perform a control operation for configurable grant timer of the uplink HARQ process.

As can be seen, since the network device can indicate the state of the HARQ feedback function of the uplink HARQ process through the DCI in the PDCCH, the control operation of configurable grant timer for the uplink HARQ process is performed through the state of the HARQ feedback function of the uplink HARQ process indicated by the DCI in the pdcsu, which is beneficial to further ensuring that the terminal device can use configurable grant timer according to the relevant configuration and scheduling operation of the network device.

Further, the terminal device 110 performing the control operation of the configuration grant timer for the uplink HARQ process according to the first state information and the second state information may include the following operations: executing control operation of a configuration grant timer for the uplink HARQ process under the condition that the first state information is different from the second state information; or, in the case that the first state information is the same as the second state information, performing a control operation of the configuration grant timer for the uplink HARQ process. It can be appreciated that the control operation for configurable granttmer of the uplink HARQ process is performed according to the relation of the second state information and the first state information.

For example, the network device 120 sends RRC configuration information to the terminal device 110, where the RRC configuration information includes 1 uplink HARQ process and 1 configuration uplink grant, the uplink HARQ process number is HARQ ID 0, and the state of the HARQ feedback function of the HARQ ID 0 is an on state. Then, the terminal device 110 receives the DCI dynamic scheduling HARQ ID 0 uplink PUSCH in the PDCCH to transmit the first data, and the configured uplink grant also configures HARQ ID 0. If the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is an off state, the terminal device 110 transmits first data using HARQ ID 0 on the DCI dynamic scheduling resource in the PDCCH, and performs a control operation of configurable grant timer corresponding to HARQ ID 0. Or if the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is still in the on state, the terminal device 110 transmits the first data using HARQ ID 0 on the DCI dynamically scheduled resource in the PDCCH, and performs the control operation of the configurable grant timer corresponding to HARQ ID 0. And whether the state of the HARQ feedback function of HARQ ID 0 is changed at the present transmission or at the present transmission and at the subsequent transmission is indicated for DCI in the PDCCH, similar to the above example.

As can be seen, since the network device can change the state of the HARQ feedback function of the uplink HARQ process through DCI in the PDCCH, and determine whether the state of the HARQ feedback function of the uplink HARQ process is changed relative to the first state information configured by the first configuration information, to perform the control operation of configurable grant timer for the uplink HARQ process, it is beneficial to further ensure that the terminal device can use the configuration grant timer corresponding to the relevant configuration and scheduling operation of the network device.

In one possible example, the control operation of the configuration grant timer of the uplink HARQ process may include any one of the following: starting a configuration grant timer of the uplink HARQ process, restarting the configuration grant timer of the uplink HARQ process or stopping the configuration grant timer of the uplink HARQ process. It can be understood that, according to whether the HARQ feedback status information of the configured uplink HARQ process in the first configuration information is on or off, the configurable grant timer operation of the uplink HARQ process is correspondingly started, restarted or stopped. Or, according to whether the DCI in the PDCCH changes the state of the HARQ feedback function of the configured uplink HARQ process in the first configuration information, correspondingly starting, restarting or stopping the configurational GrantTimer operation of the uplink HARQ process.

In one possible example, the first configuration information may further include a configuration grant timer value for the uplink HARQ process.

The configuration grant timer value is used for indicating the running duration of the configuration grant timer of the uplink HARQ process, and the configuration grant timer value comprises a first parameter value and a second parameter value.

In one possible example, terminal device 110 may further include the following operations: under the condition that the first state information is in an open state, starting or restarting a configuration grant timer of the uplink HARQ process, and setting the configuration grant timer of the uplink HARQ process as a first parameter value; and under the condition that the first state information is in a closed state, starting or restarting the configuration grant timer of the uplink HARQ process, and setting the configuration grant timer of the uplink HARQ process to be a second parameter value.

Further, in the case of considering RTT and network scheduling delay of signal transmission between the terminal device and the network device, for the uplink HARQ process for starting the HARQ feedback function, a larger configurable grant timer value may be configured. In the case of considering only the network scheduling delay of the signal transmission between the terminal device and the network device, a smaller configurable granttmer value may be configured for the uplink HARQ process that closes the HARQ feedback function.

For example, the network device 120 sends RRC configuration information to the terminal device 110, where the RRC configuration information includes 2 uplink HARQ processes, 1 configuration uplink grant, and a configurable granttmer value of the 2 uplink HARQ processes, each of the 2 uplink HARQ processes has one configurable granttmer, the 2 uplink HARQ process numbers are HARQ ID 0 and HARQ ID 1, respectively, the state of the HARQ feedback function of HARQ ID 0 is an on state, the state of the HARQ feedback function of HARQ ID 1 is an off state, and the configurable granttmer value includes a first parameter value and a second parameter value. Next, if the terminal device 110 transmits the first data on the resource indicated by the configured uplink grant, the uplink transmission of the first data uses HARQ ID 0. Since the state of the HARQ feedback function of HARQ ID 0 is an on state during the initial transmission of the first data, the terminal device 110 starts or restarts the configurable granttmer of HARQ ID 0 and sets the configurable granttmer to the first parameter value. If the terminal device 110 transmits the first data on the resource indicated by the configured uplink grant, the uplink transmission of the first data uses HARQ ID 1. Since the state of the HARQ feedback function of HARQ ID 1 is the off state during the initial transmission of the first data, the terminal device 110 starts or restarts the configurable granttmer of HARQ ID 1 and sets the configurable granttmer to the second parameter value.

It can be seen that starting or restarting the configurable granttmer of the uplink HARQ process according to the state of the HARQ feedback function of the network configured uplink HARQ process, and setting the configurable granttmer value for the corresponding configurable granttmer is beneficial to further implementing the configuration mode and the use method of the configuration grant timer of the uplink HARQ process according to the state of the HARQ feedback function of the network configured uplink HARQ process.

In one possible example, terminal device 110 may further include the following operations: under the condition that the first state information is the same as the second state information, starting or restarting a configuration grant timer of the uplink HARQ process, and setting the configuration grant timer of the uplink HARQ process as a first parameter value; and under the condition that the first state information is different from the second state information, starting or restarting the configuration grant timer of the uplink HARQ process, and setting the configuration grant timer of the uplink HARQ process to be a second parameter value.

For example, please refer to fig. 3. First, the network device 120 sends RRC configuration information to the terminal device 110, where the RRC configuration information includes 2 uplink HARQ processes, 1 configuration uplink grant, and a configurable granttmer value of the 2 uplink HARQ processes, each of the 2 uplink HARQ processes has one configurable granttmer, the 2 uplink HARQ processes are HARQ ID 0 and HARQ ID 1, a state of a HARQ feedback function of HARQ ID 0 is an on state, and a state of a HARQ feedback function of HARQ ID 1 is an off state, and the configurable granttmer value includes a first parameter value and a second parameter value. The terminal device 110 uses the 2 uplink HARQ process numbers to perform uplink transmission on the resources indicated by the configured uplink grant in a polling manner. Next, the terminal device 110 transmits an initial transmission of first data on the resource indicated by the configured uplink grant, and the uplink transmission of the first data uses HARQ ID 0. Since the state of the HARQ feedback function of HARQ ID 0 is an on state during the initial transmission of the first data, the terminal device 110 starts configurable granttmer of HARQ ID 0 and sets configurable granttmer to the first parameter value. Then, the terminal device 110 receives the uplink PUSCH of the DCI dynamic scheduling HARQ ID 0 in the PDCCH to retransmit the first data. Since the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is still in the on state, the terminal device 110 retransmits the first data using HARQ ID 0 on the first resource dynamically scheduled by the DCI in the PDCCH, and restarts the configurable grant timer of HARQ ID 0. At this time configurable granttmer is still the first parameter value. Again, the terminal device 110 receives the uplink PUSCH of DCI dynamic scheduling HARQ ID 0 in the PDCCH to newly transmit the second data. Since the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is in the off state, the terminal device 110 uses HARQ ID 0 to retransmit the second data on the second resource dynamically scheduled by the DCI in the PDCCH, restarts the configurable grant timer of HARQ ID 0, and sets the configurable grant timer to the second parameter value. Finally, the terminal device 110 receives the uplink PUSCH of the DCI dynamic scheduling HARQ ID 0 in the PDCCH to retransmit the second data. If the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is an on state, the terminal device 110 retransmits the second data using HARQ ID 0 on the third resource dynamically scheduled by the DCI in the PDCCH, restarts the configurable grant timer of HARQ ID 0, and sets the configurable grant timer to the first parameter value. And if the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is still in the off state, the terminal device 110 retransmits the second data using HARQ ID 0 on the third resource dynamically scheduled by the DCI in the PDCCH, and restarts the configurable grant timer of HARQ ID 0, where the configurable grant timer is still the second parameter value. And whether the state of the HARQ feedback function of HARQ ID 0 is changed for the DCI in the PDCCH indicates whether the current transmission of HARQ ID 0 or the current and subsequent transmissions of HARQ ID is similar to the above example.

It can be seen that, under the condition that DCI in the PDCCH is received, the configurable grant timer of the uplink HARQ process is started or restarted by determining whether the state of the HARQ feedback function of the uplink HARQ process is changed relative to the first state information configured by the first configuration information, and setting a configurable grant timer value for the corresponding configurable grant timer is beneficial to further implementing the configuration mode and the usage method of the configuration grant timer of the uplink HARQ process according to determining whether the state of the HARQ feedback function of the uplink HARQ process is changed.

In one possible example, the configuration grant timer for the uplink HARQ process includes a first configuration grant timer and a second configuration grant timer.

Further, the terminal device 110 performing the control operation of the configuration grant timer for the uplink HARQ process according to the first state information may include the following operations: starting or restarting the first configuration authorization timer under the condition that the first state information is in an on state, and setting the first configuration authorization timer as a first parameter value; stopping the second configuration grant timer if the second configuration grant timer is running; or, in the case that the first state information is in the off state, starting or restarting the second configuration authorization timer, and setting the second configuration authorization timer to the second parameter value; the first configuration grant timer is stopped in the event that the first configuration grant timer is running.

For example, the network device 120 sends RRC configuration information to the terminal device 110, where the RRC configuration information includes 2 uplink HARQ processes, 1 configured uplink grant and a configurable grant timer value, each of the 2 uplink HARQ processes has 2 configurable grant timers, i.e. a first configurable grant timer and a second configurable grant timer, the 2 uplink HARQ process numbers are HARQ ID 0 and HARQ ID 1, respectively, the state of the HARQ feedback function of HARQ ID 0 is an on state, the state of the HARQ feedback function of HARQ ID 1 is an off state, and the configurable grant timer includes a first parameter value and a second parameter value. Next, when the terminal device 110 transmits the first data on the resource to which the uplink grant indication is configured, the uplink transmission of the first data uses HARQ ID 0. Since the state of the HARQ feedback function of HARQ ID 0 is an on state during transmission of the first data, the terminal device 110 starts or restarts the first configurable granttmer of HARQ ID 0 and sets the first configurable granttmer to the first parameter value. If the second configurable granttmer of HARQ ID 0 is running, the second configurable granttmer is stopped. Alternatively, when the terminal device 110 transmits the first data on the resource indicated by the configured uplink grant, the uplink transmission of the first data uses HARQ ID 1. Since the state of the HARQ feedback function of HARQ ID 1 is the off state during the transmission of the first data, terminal device 110 starts or restarts the second configurable granttmer of HARQ ID 1 and sets the second configurable granttmer to the second parameter value. If the first configurable granttmer of HARQ ID 1 is running, the first configurable granttmer is stopped.

It can be seen that, the corresponding configurable granttmer is selected from the configurable granttmer of the uplink HARQ process through the state of the HARQ feedback function of the uplink HARQ process configured by the network to be started or restarted, and the corresponding configurable granttmer value is set for the configurable granttmer, which is favorable for further realizing the configuration mode and the use method of the configuration grant timer of the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process configured by the network.

Further, the terminal device 110 performing the control operation of the configuration grant timer for the uplink HARQ process according to the first indication information may include the following operations: starting or restarting the first configuration authorization timer and setting the first configuration authorization timer to a first parameter value under the condition that the first state information is the same as the second state information; stopping the second configuration grant timer if the second configuration grant timer is running; or, if the first state information is different from the second state information, starting or restarting the second configuration authorization timer, and setting the second configuration authorization timer to a second parameter value; the first configuration grant timer is stopped in the event that the first configuration grant timer is running.

For example, please refer to fig. 4. First, the network device 120 sends RRC configuration information to the terminal device 110, where the RRC configuration information includes 2 uplink HARQ processes, 1 configuration uplink grant, and a configurable granttmer value of the 2 uplink HARQ processes, each of the 2 uplink HARQ processes has 2 configurable granttmers, i.e., a first configurable granttmer and a second configurable granttmer, the 2 uplink HARQ processes are HARQ ID 0 and HARQ ID 1, the state of the HARQ feedback function of HARQ ID 0 is an on state, the state of the HARQ feedback function of HARQ ID 1 is an off state, and the configurable granttmer value includes a first parameter value and a second parameter value. The terminal device 110 uses the 2 uplink HARQ process numbers to perform uplink transmission on the resources indicated by the configured uplink grant in a polling manner. Next, the terminal device 110 newly transmits the first data on the resource indicated by the configured uplink grant, and the uplink transmission of the first data uses HARQ ID 0. Since the state of the HARQ feedback function of HARQ ID 0 is an on state during the new transmission of the first data, the terminal device 110 starts the first configurable granttmer of HARQ ID 0 and sets the first configurable granttmer to the first parameter value. Then, the terminal device 110 receives the uplink PUSCH of the DCI dynamic scheduling HARQ ID 0 in the PDCCH to retransmit the first data. Since the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is still in the on state, the terminal device 110 retransmits the first data using HARQ ID 0 on the first resource dynamically scheduled by the DCI in the PDCCH, and restarts the first configurable grant timer of HARQ ID 0. The first configurable granttmer is still at the first parameter value. Again, the terminal device 110 receives the uplink PUSCH of DCI dynamic scheduling HARQ ID 0 in the PDCCH to newly transmit the second data. Since the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is in the off state, the terminal device 110 uses HARQ ID 0 to newly transmit second data on a second resource dynamically scheduled by the DCI in the PDCCH, starts a second configurable granttmer of HARQ ID 0, sets the second configurable granttmer to a second parameter value, and stops the first configurable granttmer of HARQ ID 0. Finally, the terminal device 110 receives the uplink PUSCH of the DCI dynamic scheduling HARQ ID 0 in the PDCCH to retransmit the second data. If the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is an on state, the terminal device 110 retransmits the second data using HARQ ID 0 on the third resource of the DCI dynamic scheduling in the PDCCH, starts the first configurable granttmer of HARQ ID 0, sets the first configurable granttmer to the first parameter value or the second parameter value, and stops the second configurable granttmer of HARQ ID 0. And if the DCI in the PDCCH indicates that the state of the HARQ feedback function of HARQ ID 0 is still in the off state, the terminal device 110 retransmits the second data using HARQ ID 0 on the third resource dynamically scheduled by the DCI in the PDCCH, and restarts the second configurable grant timer of HARQ ID 0, where the configurable grant timer is still the second parameter value. And whether the state of the HARQ feedback function of HARQ ID 0 is changed for the DCI in the PDCCH indicates whether the current transmission of HARQ ID 0 or the current and subsequent transmissions of HARQ ID 0 is similar to the above example.

It can be seen that, in the method for using the configuration grant timer described in the embodiment of the present application, in the case that the first data of the uplink HARQ process is transmitted on the first uplink resource configured by the network, the terminal device executes the control operation of the configuration grant timer of the uplink HARQ process according to the state of the HARQ feedback function of the uplink HARQ process, and is beneficial to implementing the configuration mode and the use method of the configuration grant timer of the uplink HARQ process in the case that the NR communication system considers to turn on or off the HARQ feedback function of the uplink HARQ process, and to ensuring that the terminal device can use the configuration grant timer accordingly according to the relevant configuration and scheduling operation of the network device.
