Detailed ways

In order to have a more detailed understanding of the characteristics and technical content of the embodiments of the present application, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The attached drawings are for reference and explanation purposes only, and are not used to limit the embodiments of the present application.

Non-terrestrial communication network (Non Terrestrial Network, NTN) uses satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's area. For example, general terrestrial communication cannot cover areas where communication equipment cannot be installed, such as oceans, mountains, or deserts, or areas that cannot be covered by communication due to sparse population; while for satellite communication, due to a A satellite can cover a large area of the ground, and the satellite can orbit the earth, so theoretically every corner of the earth can be covered by satellite communications. Secondly, satellite communication has high social value. Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap with developed areas and promoting The development of these areas. Third, the satellite communication distance is long, and the increase of the communication distance will not significantly increase the cost of communication; finally, the stability of satellite communication is high, and it is not restricted by natural disasters.

Communication satellites are classified into Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) satellites, and highly elliptical satellites according to their orbital heights. Orbit (High Elliptical Orbit, HEO) satellites, etc. The following is a brief description of LEO and GEO respectively.

LEO's orbital altitude ranges from 500km to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between terminal devices is generally less than 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirement for the transmission power of the terminal equipment is not high.

The orbital height of GEO is 35786km, and the period of rotation around the earth is 24 hours. The signal propagation delay of single-hop communication between terminal devices is generally 250ms. In order to ensure the coverage of satellites and increase the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form dozens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter. Ground area.

In the NR system, the network device can configure the Discontinuous Reception (DRX) function for the terminal device. The terminal device is allowed to monitor the PDCCH non-continuously, so as to achieve the purpose of saving power for the terminal device. Each Medium Access Control (MAC) entity has a DRX configuration; DRX configuration parameters include:

1) DRX duration timer (drx-onDuration Timer), the duration of the terminal device waking up at the beginning of a DRX cycle (Cycle).

2) DRX slot offset (drx-SlotOffset), the terminal device starts drx-onDuration and the time delay of Timer.

3) DRX deactivation timer (drx-InactivityTimer), when the terminal device receives a PDCCH indicating uplink initial transmission or downlink initial transmission, the terminal device continues to monitor the duration of the PDCCH.

4) DRX downlink retransmission timer (drx-RetransmissionTimerDL): The terminal device monitors the longest duration of the PDCCH indicating downlink retransmission scheduling. Each downlink HARQ process except the broadcast HARQ process corresponds to a DRX-RetransmissionTimerDL.

5) DRX Uplink Retransmission Timer (drx-RetransmissionTimerUL): The terminal device monitors the longest duration of the PDCCH indicating uplink retransmission scheduling. Each uplink HARQ process corresponds to a DRX-RetransmissionTimerUL.

6) DRX long cycle start offset (drx-LongCycleStartOffset): used to configure the long DTX cycle (Long DRX cycle), and the subframe offset at which the Long DRX cycle and the short DRX cycle (Short DRX cycle) start.

7) DRX short cycle (drx-ShortCycle): optional configuration.

8) DRX short cycle timer (drx-ShortCycleTimer): the duration of the terminal device in the Short DRX cycle (and not receiving any PDCCH), which is an optional configuration.

9) drx-HARQ-RTT-TimerDL: The minimum waiting time required for terminal equipment to expect to receive the PDCCH indicating downlink scheduling. Each downlink HARQ process except the broadcast HARQ process corresponds to one DRX-HARQ-RTT-TimerDL;

10) drx-HARQ-RTT-TimerUL: The terminal equipment expects the minimum waiting time required to receive the PDCCH indicating the uplink scheduling. Each uplink HARQ process corresponds to a drx-HARQ-RTT-TimerUL.

If the terminal device is configured with DRX, the terminal device needs to monitor the PDCCH in DRX Active Time. DRX Active Time includes the following situations:

1) Any one of the following 5 timers is running: drx-onDurationTimer, drx-InactivityTimer, drx-RetransmissionTimerDL, drx-RetransmissionTimerUL, and ra-ContentionResolutionTimer.

2) A scheduling request (Scheduling Request, SR) is sent on the PUCCH and is in a pending state.

3) In the process of contention-based random access, the terminal device has not received the PDCCH indication scrambled by the Cell Radio Network Temporary Identifier (C-RNTI) after successfully receiving the random access response. Initial transmission.

A schematic diagram of the DRX cycle of the terminal device, as shown in Figure 1, the terminal device determines the time to start the drx-onDurationTimer according to the current short DRX cycle (Short DRX Cycle) or the long DRX cycle (Long DRX Cycle). The specific regulations are as follows:

1) If the terminal device is currently in Short DRX Cycle, and the current subframe satisfies [(SFN×10)+subframe number]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle); or

2) If the terminal device is currently in Long DRX Cycle, and the current subframe satisfies [(SFN×10)+subframe number] modulo(drx-LongCycle)=drx-StartOffset:

Then the drx-onDurationTimer is started at a time after drx-SlotOffset slots from the beginning of the current subframe.

The conditions for the terminal device to start or restart drx-InactivityTimer are:

If the terminal device receives a PDCCH indicating downlink or uplink initial transmission, the terminal device starts or restarts the drx-InactivityTimer.

The conditions for the terminal device to start and stop drx-RetransmissionTimerDL are:

When the terminal device receives a PDCCH indicating downlink transmission, or when the terminal device receives a MAC PDU on the configured downlink authorized resource, the terminal stops the drx-RetransmissionTimerDL corresponding to the HARQ process. The terminal device starts the drx-HARQ-RTT-TimerDL corresponding to the HARQ process after completing the transmission of the HARQ process feedback for this downlink transmission.

If the timer drx-HARQ-RTT-TimerDL corresponding to a certain HARQ of the terminal device times out, and the downlink data transmitted using this HARQ process is not successfully decoded, the terminal device starts the drx-RetransmissionTimerDL corresponding to the HARQ process.

The conditions for terminal equipment to start and stop drx-RetransmissionTimerUL are:

When the terminal device receives a PDCCH indicating uplink transmission, or when the terminal device sends a MAC PDU on the configured uplink authorization resource, the terminal device stops the drx-RetransmissionTimerUL corresponding to the HARQ process. The terminal device starts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process after completing the first repetition of this PUSCH.

If the timer drx-HARQ-RTT-TimerUL corresponding to a certain HARQ of the terminal device times out, the terminal device starts the drx-RetransmissionTimerUL corresponding to this HARQ process.

According to the above DRX process, it can be seen that after the terminal device completes the uplink transmission or completes the HARQ process feedback for the downlink transmission, it will first start a DRX HARQ RTT timer (for the uplink transmission is drx-HARQ-RTT-TimerUL, for the downlink transmission It is drx-HARQ-RTT-TimerDL), the terminal device is in the dormant state during the running of the DRX HARQ RTT timer and does not monitor the PDCCH. After the DRX HARQ RTT timer expires, the terminal device starts monitoring the uplink retransmission schedule or determines whether to start monitoring the downlink retransmission schedule according to the feedback of the HARQ process. Among them, drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL are semi-statically configured by network equipment through radio resource control (Radio Resource Control, RRC) signaling.

In the NR system, both the uplink transmission and the downlink transmission support the HARQ mechanism; therefore, the drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL two timers are used in the DRX process. The duration of these two timers is It characterizes the minimum time interval required by the terminal from the uplink transmission to receiving the retransmission schedule issued by the network device; the minimum time interval includes the round trip delay (RTT) and the processing time of the network device. In NTN, the signal propagation delay between terminal equipment and satellites has increased significantly. In order to enable network equipment to more accurately control drx-HARQ-RTT-TimerUL and drx-HARQ-RTT-TimerDL, it can be targeted at drx-HARQ-RTT- The start of TimerUL and drx-HARQ-RTT-TimerDL introduces a time offset (offset), that is, after the terminal device completes PUSCH transmission or NACK feedback for downlink reception, drx-HARQ-RTT-TimerUL is started after another offset. Or drx-HARQ-RTT-TimerDL.

Compared with the cellular network used in the traditional NR system, the signal propagation delay between the terminal equipment and the satellite in NTN has increased significantly. In order not to increase the number of HARQ processes and ensure the continuity of data transmission, the standardization process is currently under discussion to enable or The HARQ plan was closed, and the following clear conclusions were formed:

(1) The network equipment can be configured to enable the HARQ function.

(2) If the HARQ function is turned off, the terminal device does not need to send HARQ feedback for the PDSCH to the network device.

(3) When HARQ feedback is turned off, in order to ensure the reliability of data transmission, HARQ retransmission is still supported.

(4) The configuration of enabling or disabling the HARQ function can be performed based on the terminal device or the HARQ process. For the configuration based on the terminal device, that is, the HARQ function of all HARQ processes of the configuration terminal device is in the on or off state at the same time. For the HARQ process-based configuration method, that is, for multiple HARQ processes of a terminal device, the HARQ function of some of the HARQ processes can be configured to be in the on state, and the HARQ function of the other part of the HARQ process is to be in the off state.

However, for scenarios where the HARQ function is switched from on to off, or the HARQ function is switched from off to on, in order to simplify the processing flow of the communication system, it is not clear what operations the terminal device needs to perform; and the HARQ function is switched from on to off, or In the scenario where the HARQ function is switched from off to on, how to implement the DRX process has not yet been clarified.
