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.

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 divided 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 New Radio (NR) system, the network device can configure the DRX function for the terminal device. The terminal device is allowed to monitor the physical downlink control channel (Physical Downlink Control Channel, 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-onDuration Timer, the duration of the terminal device waking up at the beginning of a DRX cycle (Cycle).

2) DRX-SlotOffset (DRX-SlotOffset), the terminal device starts DRX-onDuration Timer delay.

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. Except for the broadcast Hybrid Automatic Repeat reQuest (HARQ) process, each downlink 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 being in the Short DRX cycle (and not receiving any PDCCH) is an optional configuration.

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

10) DRX-HARQ-RTT-TimerUL: The minimum waiting time required for the terminal device to expect 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 to start or restart drx-InactivityTimer are:

If the terminal receives a PDCCH indicating downlink or uplink initial transmission, the terminal 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.

The NR system supports network devices to configure synchronization signal block (Synchronization Signal Block, SSB) measurement and channel status indicator reference signal (Channel Status Indicator Reference Signal, CSI-RS) measurement for connected terminal devices. For SSB measurement, the network device configures the SSB frequency associated with the measurement object for the terminal device; since the NR system supports the transmission of multiple different sub-carrier intervals, the measurement object needs to indicate the measurement-related SSB sub-carrier interval. For CSI-RS measurement, a reference frequency point that maps CSI-RS to physical resources is configured in the measurement object. For the measurement configuration of the SSB reference signal, the measurement object additionally indicates the time window information of the SSB measurement, that is, the SSB measurement timing configuration (SS/PBCH block measurement timing configuration, SMTC) information. Further, the network device may also instruct the terminal device to measure which SSBs in the SMTC (for example, SSB-ToMeasure) and other information. For the measurement configuration of the CSI-RS reference signal, the measurement object includes the configuration of the CSI-RS resource.

For terrestrial cellular networks, the TS38.133 protocol defines the measurement requirements for wireless link detection (Beam Failuer Detection, BFD) and radio link monitoring (Radio Link Monitoring, RLM). The measurement requirements can be divided into There are two situations when DRX is configured for terminal equipment and DRX is not configured. Taking BFD measurement as an example, the terminal device needs to detect whether the radio link quality on the reference signal (Reference Signal, RS) resource is lower than the threshold Q _{out_LR within the time T Evaluate_BFD} . If the RS signal quality is lower than Q _{out_LR} , the terminal device needs to send an L1 beam failure indication to the higher layer. Two consecutive L1 indications are separated by at least T _{Indication_interval_BFD} time. Among them, T _{Evaluate_BFD} represents the evaluation time corresponding to the quality of the radio link, and T _{Indication_interval_BFD} represents the time interval for evaluating the quality of the two adjacent radio links.

When DRX is not configured, _{the value of T Indication_interval_BFD} is max (2ms, T _{SSB-RS, M} ) or max (2ms, T _{CSI-RS, M} );

When configuring DRX, if the DRX cycle is less than or equal to 320ms, _{the value of T Indication_interval_BFD} is Max(1.5*DRX_cycle_length,1.5*T _SSB-RS,M ) or Max(1.5*DRX_cycle_length,1.5*T _CSI-RS,M );

If the DRX cycle is greater than 320ms, _{the value of T Indication_interval_BFD} is the DRX cycle.

The value of T _{Evaluate_BFD_SSB} is similar to the value of T _{Indication_interval_BFD} , as shown in Table 1 below. When DRX is not configured, T _{Evaluate_BFD_SSB} takes the maximum value of 50ms and 5P times the SSB period as the BFD measurement requirement; when DRX is configured, the measured requirement can be several times the DRX period.

Table 1

When the terminal device is configured with DRX, the measurement requirement of Radio Resource Management (RRM) in the terrestrial cellular network is: BFD/RLM measurement is evaluated once in several DRX cycles, and such measurement requirement will not affect relatively low-speed terminals Device connection management, and can achieve the purpose of power saving. However, in the satellite network, the relative speed of LEO satellites relative to the ground is very fast. At this time, if the measurement results are still evaluated in a few DRX cycles, it is likely that the channel quality changes too fast, and the sampling points at different times are different. With relevance, the channel quality cannot be tracked in time and accurately, and the evaluated measurement result deviates from the true real-time channel quality.
