Detailed Description

So that the manner in which the features and techniques of the embodiments of the present application can be understood in more detail, a more particular description of the application, briefly summarized below, may be had by reference to the appended drawings, which are not intended to be limiting of the embodiments of the present application.

NTN provides communication services to terrestrial users by way of satellite communications. Satellite communications have many unique advantages over terrestrial cellular communications. Firstly, satellite communication is not limited by user regions, for example, general land communication cannot cover areas where communication equipment cannot be set up, such as oceans, mountains, deserts and the like, or communication coverage cannot be performed due to sparse population; for satellite communication, since one satellite can cover a larger area of the ground, and the satellite can orbit around the earth, theoretically every corner of the earth can be covered by satellite communication. And secondly, satellite communication has higher 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 increasing the communication distance does not significantly increase the cost of communication; 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, and high elliptical Orbit (HIGH ELLIPTICAL Orbit, HEO) satellites, etc. according to the Orbit heights. The LEO and GEO are briefly described below, respectively.

The LEO has a track height in the range of 500km to 1500km, with a corresponding track period of about 1.5 hours to 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.

The orbit height of GEO is 35786km and the period of rotation around the earth is 24 hours. 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.

In a New Radio (NR) system, a network device may configure a DRX function for a terminal device. The terminal equipment discontinuously monitors the physical downlink control channel (Physical Downlink Control Channel, PDCCH), so that the purpose of saving electricity of the terminal equipment is achieved. Each medium access control (Medium Access Control, MAC) entity has a DRX configuration; the configuration parameters of DRX include:

1) A DRX duration Timer (DRX-onDuration Timer), the duration for which the terminal device wakes up at the beginning of one DRX Cycle (Cycle).

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

3) And a DRX deactivation timer (DRX-InactyityTimer), wherein after the terminal equipment receives a PDCCH indicating uplink initial transmission or downlink initial transmission, the terminal equipment continues to monitor the duration of the PDCCH.

4) DRX downlink retransmission timer (DRX-RetransmissionTimerDL): the terminal device listens for the longest duration of the PDCCH indicating the downlink retransmission schedule. Each downlink hybrid automatic repeat request (HARQ) process except for the broadcast Hybrid Automatic Repeat reQuest HARQ process corresponds to one DRX-RetransmissionTimerDL.

5) DRX uplink retransmission timer (DRX-RetransmissionTimerUL): the terminal device listens for the longest duration of the PDCCH indicating the uplink retransmission schedule. Each uplink HARQ process corresponds to one DRX-RetransmissionTimerUL.

6) DRX long cycle start offset (DRX-LongCycleStartOffset): for configuring a Long DTX period (Long DRX cycle), and subframe offsets at which the Long DRX cycle and the short DRX cycle (ShortDRX Cycle) start.

7) DRX short cycle (DRX-ShortCycle): is an alternative configuration.

8) DRX short cycle timer (DRX-ShortCycle Timer): the duration that the terminal device is in Short DRX cycle (and does not receive any PDCCH) is an optional configuration.

9) DRX-HARQ-RTT-TimerDL: the terminal equipment expects to receive the minimum waiting time required by the PDCCH indicating the downlink scheduling, and each downlink HARQ process except the broadcast HARQ process corresponds to one DRX-HARQ-RTT-TimerDL;

10 DRX-HARQ-RTT-TimerUL): the terminal device expects to receive the minimum waiting time required for indicating the PDCCH of the uplink scheduling, and each uplink HARQ process corresponds to one drx-HARQ-RTT-TimerUL.

If the terminal device is configured with DRX, the terminal device needs to monitor PDCCH at DRX ACTIVE TIME. DRX ACTIVE TIME includes the following cases:

1) Any one of the following 5 timers is running: DRX-onDuration Timer, DRX-INACTIVITY TIMER, DRX-RetransmissionTimerDL, DRX-RetransmissionTimerUL and ra-ContentionResolution Timer.

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

3) In the contention-based random access procedure, the terminal device has not received one initial transmission of the cell radio network temporary identity (Cell Radio Network Temporary Identifier, C-RNTI) scrambled PDCCH indication after successful reception of the random access response.

As shown in fig. 1, the terminal device determines the time for starting the DRX-onDuration Timer according to the current Short DRX Cycle (Short DRX Cycle) or Long DRX Cycle (Long DRX Cycle), which is specifically defined as follows:

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

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

The drx-onDuration Timer is started at a time after drx-SlotOffset slots at the beginning of the current subframe.

The conditions for starting or restarting the drx-InactvityTimer are as follows:

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

The conditions for starting and stopping drx-RetransmissionTimerDL of the terminal device are as follows:

When the terminal equipment receives a PDCCH indicating downlink transmission or receives a MAC PDU on the configured downlink grant resource, the terminal stops the drx-RetransmissionTimerDL corresponding to the HARQ process. After completing the transmission fed back by the HARQ process for the downlink transmission, the terminal equipment starts the drx-HARQ-RTT-TimerDL corresponding to the HARQ process.

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

The conditions for starting and stopping drx-RetransmissionTimerUL of the terminal device are as follows:

When the terminal equipment receives a PDCCH indicating uplink transmission or when the terminal equipment transmits a MAC PDU on the configured uplink authorized resource, the terminal equipment stops the drx-RetransmissionTimerUL corresponding to the HARQ process. After finishing the first repetition transmission (repetition) of the PUSCH, the terminal device starts the drx-HARQ-RTT-TimerUL corresponding to the HARQ process.

If the timer drx-HARQ-RTT-TimerUL corresponding to a certain HARQ of the terminal equipment is timed out, the terminal equipment starts the drx-RetransmissionTimerUL corresponding to the HARQ process.

The NR system supports network devices to configure synchronization signal block (Synchronization Signal Block, SSB) measurements and channel state indication reference signal (Channel Status Indicator REFERENCE SIGNAL, CSI-RS) measurements for connected terminal devices. For SSB measurement, the network equipment configures SSB frequency points associated with a measurement object for the terminal equipment; since the NR system supports transmission of a plurality of different subcarrier spacings, the SSB subcarrier spacings related to the measurement need to be indicated in the measurement object. For CSI-RS measurement, a reference frequency point for mapping the CSI-RS to a physical resource is configured in a measurement object. For the measurement configuration of the SSB reference signal, time window information of the SSB measurement, that is, SSB measurement timing configuration (SS/PBCH block measurement timing configuration, SMTC) information is additionally indicated in the measurement object. Further, the network device may also instruct the terminal device as to which SSBs to measure (e.g., SSB-ToMeasure) within the SMTC. For measurement configuration of the CSI-RS reference signal, the measurement object comprises configuration of the CSI-RS resource.

For terrestrial cellular networks, the TS38.133 protocol defines measurement requirements (requirements) for radio link detection, such as beam failure detection (Beam Failuer Detection, BFD) and radio link monitoring (Radio Link Monitoring, RLM), which can be divided into two cases, DRX configured and DRX not configured for the terminal device. Taking BFD measurement as an example, the terminal device needs to complete detecting whether the radio link quality on the reference signal (REFERENCE SIGNAL, RS) resource is below the threshold Q _{out_LR} within a 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 at least separated by a time T _{Indication_interval_BFD}. Wherein, T _{Evaluate_BFD} represents an evaluation time corresponding to the quality of the wireless link, and T _{Indication_interval_BFD} represents a time interval for evaluating the quality of the wireless link adjacent to two times.

When the DRX is not configured, the value of T _{Indication_interval_BFD} is max (2 ms, T _SSB-RS,M) or max (2 ms, 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 period is greater than 320ms, the value of T _{Indication_interval_BFD} is the DRX period.

The values of T _{Evaluate_BFD_SSB} are similar to those of T _{Indication_interval_BFD}, as shown in Table 1 below. When DRX is not configured, T _{Evaluate_BFD_SSB} takes the maximum of the two SSB periods of 50ms and 5P times as the requirement for BFD measurement; when DRX is configured, the measured requirement may be a multiple of the DRX cycle.

TABLE 1

When the terminal device is configured with DRX, measurement requirements for radio resource management (Radio Resource Management, RRM) in the terrestrial cellular network are: several DRX cycles evaluate one BFD/RLM measurement, such measurement requirement does not affect connection management of relatively low speed terminal devices and may achieve power saving purposes. However, in satellite networks, especially LEO satellites, the relative speed with respect to the ground is very fast, which in this case may result in too fast a channel quality change if the measurement result is still evaluated once with several DRX cycles, and there is no correlation between the sampling points at different moments, so that the channel quality cannot be tracked timely and accurately, and the evaluated measurement result deviates from the real-time channel quality.

Taking BFD by the terminal device based on the SSB reference signal as an example, the description is given for the second time (T _{Evaluate_BFD}) related to the SSB reference signal period:

If DRX is not configured, the measurement requirement may include a second time (T _{Evaluate_BFD}) equal to N ₁*T_SSB-RS; where T _SSB-RS is the SSB reference signal period, N ₁ may be a protocol predefined constant, and N ₁ is a positive integer.

If DRX is configured, the second time (T _{Evaluate_BFD}) may be equal to N ₂*T_SSB-RS during the first DRX configuration interval. The first DRX configuration interval may be DRX cycle_1 or less; where T _SSB-RS is the SSB reference signal period, N ₂ may be a protocol predefined constant, and N ₂ is a positive integer.

If DRX is configured, the second time (T _{Evaluate_BFD}) may be equal to N ₃*T_SSB-RS in a second DRX configuration interval. The second DRX configuration interval may be drx_cycle_1 < DRX cycle_2; where T _SSB-RS is the SSB reference signal period, N ₃ may be a protocol predefined constant, and N ₃ is a positive integer.

Similarly, if DRX is configured, the second time (T _{Evaluate_BFD}) may be equal to N _n+1*T_SSB-RS in the nth DRX configuration interval. The nth DRX configuration interval may be DRX cycle > drx_cycle_n-1; where T _SSB-RS is the SSB reference signal period, N _n+1 may be a protocol predefined constant, and N _n+1 is a positive integer.
