Wherein, the method comprises the following steps: the user equipment receives an instruction sent by the network equipment; and under the conditions that the process of the downlink hybrid automatic repeat request is determined to be blocked and the transmission time timer corresponding to the specified downlink hybrid automatic repeat request is determined to be overtime, the user equipment monitors the physical downlink control channel according to the indication signaling. The invention solves the technical problem of overlong downlink scheduling delay caused by that the user equipment needs to wait for a long time to restart the discontinuous reception continuous timer so as to monitor the PDCCH for indicating scheduling after the process of the hybrid automatic repeat request HARQ is recovered to an available HARQ process from the process blockage condition of the hybrid automatic repeat request HARQ in the prior art under the condition of the process blockage of the hybrid automatic repeat request HARQ.
Description
The present invention relates to the field of communications technologies, and in particular, to a method, a device, and a system for communication between a user equipment and a network device.
In Non-Terrestrial communication Network (NTN) technology under study by the existing 3rd Generation Partnership Project (3 GPP), the NTN generally provides communication services to Terrestrial users by means of satellite communication. Compared with the ground cellular network communication, the satellite communication is not limited by user regions and has greater social value, namely, the satellite communication can be covered in remote mountain areas and poor and lagged countries or areas with lower cost, so that people in the areas can enjoy advanced voice communication and mobile internet technologies, the digital gap between the areas and developed areas is favorably reduced, and the development of the areas is promoted; the satellite communication distance is long, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.
Among them, communication satellites are classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Orbit (LEO) satellites, High-elliptic Orbit (HEO) satellites, and the like according to the difference in orbital height. The main studies at the present stage are LEO and GEO.
In 5G communication (New Radio, NR for short), in an existing mechanism, if a transmission time timer (drx-HARQ-RTT-TimerDL) corresponding to a certain hybrid automatic repeat request (HARQ) of a terminal is overtime and downlink data transmitted by using the HARQ process is unsuccessfully decoded, the terminal starts a retransmission timer (drx-retransmission TimerDL) corresponding to the HARQ process.
If the network sets the HARQ feedback functions of all HARQ processes of a User Equipment (UE) to an on state, and the number of uplink/downlink transmission opportunities that can be obtained by the UE within Round Trip Time (RTT) of signal transmission between the network and the UE is greater than the number of uplink/downlink HARQ processes available to the UE, uplink/downlink HARQ process blocking occurs, that is, all uplink/downlink HARQ processes of the UE are used and are in the period of operation of the RTT timer, and at this Time, the network does not have an available HARQ process even if it is expected to schedule uplink/downlink transmission of the UE.
When the RTT timer corresponding to the first used HARQ process times out, for uplink HARQ, the UE starts a discontinuous reception uplink retransmission timer corresponding to the uplink HARQ process, so that the UE can enter a discontinuous reception Active Time (DRX Active Time), and thus the UE can monitor a Physical Downlink Control Channel (PDCCH for short) scheduled by a network. For downlink HARQ, the UE starts the discontinuous reception downlink retransmission timer corresponding to the downlink HARQ process only when the UE feeds back non-acknowledgement (NACK) to the downlink HARQ process, and the UE does not start the discontinuous reception downlink retransmission timer corresponding to the downlink HARQ process if the UE feeds back Acknowledgement (ACK) to the downlink HARQ process. Thus, even if the network desires to schedule downlink transmission for the UE and the UE also has available downlink HARQ processes, the UE needs to wait until the UE starts an activation timer (DRX-onDurationTimer) at the next DRX cycle before scheduling the UE. Especially if the HARQ is blocked for a Long time, the UE may switch to a Long discontinuous reception cycle (Long DRX cycle) due to timeout of a short cycle timer (DRX-short timer) caused by not scheduling for a Long time. Thus, the UE needs to wait longer to start DRX-onduration timer (the duration of UE wake-up at the beginning of one DRX Cycle) into DRX Active Time.
In view of the above problem that in the case of process congestion of hybrid automatic repeat request HARQ, in the prior art, after recovering from the case of process congestion of hybrid automatic repeat request HARQ to an available HARQ process, the ue needs to wait for a long time before restarting the drx persistent timer to monitor the PDCCH indicating scheduling, which results in an excessively long downlink scheduling delay, an effective solution has not been proposed at present.

In an alternative implementation, the method for user equipment communication provided in the embodiment of the present application is as follows:
in the process of implementing the method for user equipment communication provided by the embodiment of the present application, the method can be implemented by three implementation manners, where the three implementation manners include:
the first method is as follows: the network equipment indicates the UE to enter DRX Active Time after the transmission Time timer corresponding to the first downlink HARQ is overtime;

the third method comprises the following steps: and the network equipment indicates the UE to switch to a short discontinuous reception cycle (short DRX cycle) after the transmission time timer corresponding to the first downlink HARQ is overtime.

in the first mode: the RRC message includes: communication parameters of discontinuous reception (related parameters configuring DRX) and configuration parameters of a process of a downlink hybrid automatic repeat request (configuration parameters of a process of downlink HARQ), wherein,
the configuration parameters of the downlink HARQ process comprise: long Discontinuous Reception cycle (Long DRX cycle), active timer (DRX-onDurationTimer), inactive timer (DRX-inactivity timer), transmission time timer (DRX-HARQ-RTT-TimerDL), and retransmission timer (DRX-retransmission TimerDL), where DRX is Discontinuous Reception, i.e., Discontinuous Reception.
The configuration parameters of the downlink HARQ process comprise: and the number of the downlink HARQ processes is equal to the number of the downlink HARQ processes, and the HARQ feedback functions of all the downlink HARQ processes are configured to be in an open state.
In the second mode: the RRC message includes: communication parameters of discontinuous reception (related parameters for configuring DRX), configuration parameters of a process of a downlink hybrid automatic repeat request (configuration parameters of a process of downlink HARQ), and a first timer, wherein,
the configuration parameters of the downlink HARQ process comprise: long DRX cycle, DRX-onDurationTimer, DRX-inactivytytimeter, DRX-HARQ-RTT-TimerDL, DRX-retransmission TimerDL.
The configuration parameters of the downlink HARQ process comprise: the number of the downlink HARQ processes is determined, and the HARQ feedback functions of all the downlink HARQ processes are configured to be in an open state;

Based on the RRC information of the three implementation manners, when the transmission time timer of the process of the downlink hybrid automatic repeat request is expired, the ue enters the discontinuous reception activation time according to the instruction when the transmission time timer of the process of the downlink hybrid automatic repeat request is stopped, and the monitoring on the physical downlink control channel is specifically as follows:
in the first mode, after the network device indicates that the UE times out the transmission Time timer corresponding to the first downlink HARQ process, the UE enters DRX Active Time as follows:
optionally, when it is determined that a process of a downlink hybrid automatic repeat request is blocked and it is determined that a transmission time timer corresponding to a specified downlink hybrid automatic repeat request is overtime, the monitoring, by the user equipment, of the physical downlink control channel according to the indication signaling includes:

The indication instruction specifies that the indication instruction is effective only once, namely after the UE receives the indication instruction, the DRX Active Time is entered when the first Time timeout occurs for DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ.
The embodiment of the application provides two service scenes:
a first service scenario: for a Physical Downlink Shared Channel (PDSCH) transmission of a dynamic scheduling indication:
step 1: when the UE receives the PDCCH indicating that a certain downlink HARQ process is used for PDSCH transmission, the UE stops a retransmission timer (drx-retransmission timer dl) corresponding to the downlink HARQ process.
Step 2: and the UE starts a transmission time timer (drx-HARQ-RTT-TimerDL) corresponding to the downlink HARQ process after finishing the transmission of the ACK/NCAK feedback aiming at the downlink transmission.
And step 3: and if the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process is overtime and the UE feeds back NACK for the downlink transmission, the UE starts the drx-retransmission TimerDL corresponding to the downlink HARQ process.
And 4, step 4: and if the network equipment indicates that the UE enters DRX Active Time after the DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process is overtime and the current downlink HARQ process is the first downlink HARQ process, the UE enters DRX Active Time after the DRX-HARQ-RTT-TimeDL corresponding to the downlink HARQ process is overtime.
Service scene two: for PDSCH transmissions that occur on the configured downlink grant:
step 1: when the UE receives a MAC PDU (MAC Protocol Data unit, Protocol Data unit of the MAC layer) on the configured downlink grant resource, the UE stops drx-retransmission timerdl corresponding to the downlink HARQ process.
Step 2: and the UE starts drx-HARQ-RTT-TimeDL corresponding to the downlink HARQ process after finishing the transmission of the ACK/NCAK feedback aiming at the downlink transmission.
And step 3: and if the drx-HARQ-RTT-TimerDL corresponding to the downlink HARQ process is overtime and the UE feeds back NACK for the downlink transmission, the UE starts the drx-retransmission TimerDL corresponding to the downlink HARQ process.
And 4, step 4: and if the network indicates that the UE enters DRX Active Time after the Time-out of DRX-HARQ-RTT-TimerDL corresponding to the first downlink HARQ process and the current downlink HARQ process is the first downlink HARQ process, the UE enters DRX Active Time after the Time-out of DRX-HARQ-RTT-TimerDL corresponding to the downlink HARQ process.
In an alternative embodiment, as shown in fig. 2, the process is embodied in a first mode by combining the above examples of the present application, and the following examples are taken as examples to illustrate:
