[0002] The present disclosure relates to the field of communication technology, and in particular to an operation decision method, an information transmission method, a terminal device, and a network device. [Background technology]

[0003] In a discontinuous reception (DRX) mode, the terminal device monitors the physical downlink control channel (PDCCH) periodically, rather than continuously; that is, in the DRX mode, a DRX cycle includes an active cycle and an inactive cycle, in which the terminal device monitors the PDCCH in the active cycle and does not monitor the PDCCH in the inactive cycle, thus avoiding the terminal device from monitoring continuously, thereby achieving the purpose of power saving.

[0004] However, in the process of communication between a terminal device and a network device, data needs to be transmitted through the network. However, the terminal device is likely to encounter a situation where there is no network coverage during the active period, and cannot achieve effective monitoring even when in the active period, which makes it likely to waste power. In other words, the power saving effect of the terminal device in DRX mode is poor. Summary of the Invention [Problem to be solved by the invention]

[0025] Referring to FIG. 1, FIG. 1 is a flowchart of an operation decision method provided by an embodiment of the present disclosure, which is executed by a terminal device, and includes the following steps 101-102.

[0026] Step 101: Receive network assistance information and a first state parameter sent from a network device.

[0027] Step 102: Determine an operation of the terminal device based on the network assistance information and the first state parameter.

[0028] It should be noted that the network assistance information may be used to determine a network coverage situation corresponding to the terminal device, and the first state parameter may be understood as a parameter affecting the terminal device state. The network device transmits the network assistance information and the first state parameter to the network device, and the terminal device can determine an operation of the terminal device based on the network assistance information and the first state parameter after receiving the network assistance information and the first state parameter.

The beam information of the non-terrestrial network may be used to determine the effective coverage of the satellite to the terminal device, and further, based on the antenna gain of the beam, the effective coverage of the satellite to the terminal device may be more accurately determined.

[0034] In one embodiment, the step of receiving network assistance information transmitted from the network device comprises: receiving system messages and / or dedicated signaling transmitted from the non-terrestrial network node and / or the other network node and reading network assistance information from the system messages and / or dedicated signaling; receiving a system message and / or dedicated signaling transmitted from the non-terrestrial network node and / or the other network node a plurality of times; and reading the network assistance information from the system message and / or dedicated signaling.

[0035] It should be noted that the other network node may refer to other network nodes other than the non-terrestrial network node. It should be noted that the above network device may be a non-terrestrial network node and / or other network node, and when the memory of the non-terrestrial network node is limited or the size of the transmitted signaling is limited due to the large size of the ephemeris information, it may be transmitted by multiple network nodes, and the network node transmits information of different satellites in batches according to time.

[0036] In one embodiment, the step of receiving a system message and / or dedicated signalling transmitted from the non-terrestrial network node and / or the other network node and reading the network assistance information from the system message and / or the dedicated signalling comprises: The terminal device combines system messages and / or dedicated signaling transmitted from the non-terrestrial network node and / or the other network node to obtain first combination information, and reads network assistance information from the first combination information; The terminal device combines system messages and / or dedicated signaling transmitted from a plurality of non-terrestrial network nodes to obtain second combination information; and reads network assistance information from the second combination information.

[0037] For example, the terminal device obtains a first portion of ephemeris information from satellite network node 1, and obtains a second portion of ephemeris information from satellite network node 2, and combines to obtain the required or complete ephemeris information; Or the terminal device needs to obtain a first part of ephemeris information from the satellite network node 1, and obtain a second part of ephemeris information and a third part of ephemeris information from the satellite network node 2 and the satellite network node 3, respectively, and combine them to obtain the required or complete ephemeris information; Or the terminal device needs to obtain the first part of the ephemeris information from the satellite network node 1, and obtain the second part and the third part of the ephemeris information from the satellite network node 2 and the satellite network node 3 in the T2 time period and the T3 time period, respectively, and combine them to obtain the required or complete ephemeris information; Or the terminal device needs to obtain the first part of the ephemeris information from the satellite network node 1, and then obtain the second part of the ephemeris information and the third part of the ephemeris information from the SIBx (system message x), SIBy (system message y) of the satellite network node 2 and the SIBx of the satellite network node 3 respectively, and combine them to obtain the required or complete ephemeris information; Or, the terminal device obtains information of one transmission period required to obtain necessary or complete ephemeris information from the satellite network node 1, transmits information of a starting position, and the terminal device obtains the first part of ephemeris information, the second part of ephemeris information and the third part of ephemeris information in the T1 time period, the T2 time period and the T3 time period respectively, and combines them to obtain the necessary or complete ephemeris information; Or, the terminal device obtains information of one transmission period required to obtain necessary or complete ephemeris information from the satellite network node 1, transmits information of a starting position, and the terminal device obtains the first part of ephemeris information, the second part of ephemeris information and the third part of ephemeris information from SIBx, SIBy and SIBz in the T1 time period, the T2 time period and the T3 time period, respectively, and combines them to obtain the necessary or complete ephemeris information; Alternatively, the terminal device may obtain information of one transmission period required to obtain the required or complete ephemeris information from the satellite network node 1, transmit information of the starting position, and the terminal device may obtain the first part of the ephemeris information, the second part of the ephemeris information and the third part of the ephemeris information from the SIBx in the T1 time period, the T2 time period and the T3 time period, and combine them to obtain the required or complete ephemeris information.

[0038] The above methods may be used in partial or complete combination.

[0039] The above information may be provided to the terminal device by the non-terrestrial network, the terrestrial network and / or the core network.

[0040] Due to the large size of the ephemeris information, when the memory of a non-terrestrial network node is limited or the size of the signaling to be transmitted is limited, it is transmitted by multiple network nodes and combined by a terminal device to obtain auxiliary information such as the positions and beams of more satellites.

[0041] In one embodiment, the step of receiving a system message and / or dedicated signalling transmitted from the non-terrestrial network node and / or the other network node a plurality of times and reading the network assistance information from the system message and / or dedicated signalling comprises: a terminal device receiving a system message and / or dedicated signaling transmitted from a non-terrestrial network node multiple times, combining the system message and / or dedicated signaling to obtain third combination information, and reading network assistance information from the third combination information; the terminal device transmitting the system messages and / or dedicated signalings transmitted from other network nodes multiple times and combining them to obtain fourth combination information, and reading the network assistance information from the fourth combination information; The method includes at least one of the steps of: receiving, by the terminal device, system messages and / or dedicated signaling transmitted from the non-terrestrial network node and the other network node a plurality of times, combining them to obtain fifth combination information, and reading network assistance information from the fifth combination information.

[0042] That is, in this embodiment, the information of different satellites is sent in batches by the network nodes according to time, and then combined by the terminal device to obtain auxiliary information such as the positions and beams of more satellites.

[0043] In one embodiment, a method for receiving a short message sent from a network device, the short message including a first identifier indicating whether information related to a non-terrestrial network is available, wherein the terminal device obtains network assistance information based on the first identifier; Receive a plurality of first association relationships including system messages of segments of network assistance information broadcast by the network device in a system message; and obtain network assistance information based on the first association relationships by the terminal device, the first association relationships including a number and / or an order indicating at least one system message of the segments of network assistance information; receiving a second association relationship including a system message of at least one segment of network assistance information broadcast in the system message by the plurality of network devices; Receive an SIB broadcast by a network device, and the SIB includes a first field, where the terminal device performs the following steps based on the information indicated by the first field: the SIB contains network aiding information or does not contain network aiding information; Whether the network auxiliary information contained in the SIB is complete or partial; The location of the segment of network assistance information included in the SIB in the network assistance information; whether the network assistance information segment contained in the SIB is followed by a related network assistance information segment; determining at least one of: the SIB is the last SIB containing ephemeris information or is not the last SIB containing ephemeris information; Here, the second association relationship is: Other network device information carrying the location of a segment of network auxiliary information; Number of segments of network auxiliary information, Number of satellites and / or satellite information; the SIB number in which the segment of network auxiliary information is located; Here, the terminal device obtains the network assistance information based on the second association relationship.

[0044] The short message may include a first identifier, and the first identifier may indicate network assistance information, and the terminal device may obtain the network assistance information based on the indication of the first identifier. The broadcast association relationship is an association relationship of a plurality of SIBs, and a SIB in the plurality of SIBs includes some network assistance information, and the terminal device may obtain the network assistance information based on the association relationship. Also, the network device may receive a SIB broadcasted by the network device, and the SIB may include a first field, for example, a sib-Seg field, and the terminal device may, based on the information indicated by the field, Whether the SIB includes network auxiliary information; Whether the network assistance information contained in the SIB is complete or partial; The location of a portion of the network assistance information included in the SIB in the network assistance information; whether the network assistance information segment included in the SIB has a subsequent related network assistance information segment; The SIB can be determined to be at least one of the last SIB containing ephemeris information or not the last SIB containing ephemeris information, e.g., if set to true, it indicates that there are related SIBs broadcasting ephemeris information after this one, and if set to false, it indicates that this is the last SIB containing ephemeris information.

[0045] Specifically, for example, a new identifier is added to the short message to indicate whether or not there is satellite information, and the terminal obtains related ephemeris information according to the instruction from the identifier, The network node broadcasts in the system information a correlation relationship of a plurality of information messages including ephemeris information, and the terminal device obtains the related ephemeris information according to the correlation relationship; A field (e.g., sib-Seg) is added to system messages containing ephemeris information, which, when set to true, indicates that there are further SIBs broadcasting ephemeris information, and, when set to false, indicates that this is the last SIB containing ephemeris information.

[0046] In one embodiment, the DRX parameters include a time length of a plurality of timers for DRX, the plurality of timers including a DRX inactivity timer, the DRX inactivity timer being turned on when the terminal device receives a physical downlink control channel (PDCCH) and the PDCCH indicates a new data transmission; The step of determining an operation of the terminal device based on the network assistance information and the first state parameter includes: entering an inactive state if, during operation of the DRX inactivity timer, it is determined based on network assistance information that no beam is available during the operation period of the DRX inactivity timer; during operation of the DRX inactivity timer, if it is determined based on the network assistance information that a duration length during which there is no available beam in the operation period of the DRX inactivity timer is shorter than the time length of the DRX inactivity timer and longer than a first time length, the terminal device enters an inactive state, and if the duration length during which there is no available beam in the operation period of the DRX inactivity timer expires, the terminal device enters an active state; maintaining a current active state when it is determined, based on network assistance information, during operation of the DRX inactivity timer that a duration during which there is no available beam during the operation period of the DRX inactivity timer is equal to or less than a first duration.

[0047] As shown in FIG. 2, the DRX inactivity timer, i.e., the drx-InactivityTimer, is turned on when a physical downlink control channel (PDCCH) is received and indicates that it is a new data transmission, and enters a sleep state (inactive state) when it times out. During the operation of the drx-InactivityTimer, if it detects that there is no available beam in combination with the network assistance information sent from the network device, it enters the sleep state in advance. If the duration nonB1 of no available beam is equal to or greater than the first time k1 during the middle of the operation of the drx-InactivityTimer, it enters the sleep state, the timer is not reset, continues to operate, and is woken up after the end of nonB1, and enters the valid state (active state). If the duration nonB1 of no available beam is smaller than k1 during the middle of the operation of the drx-InactivityTimer, it does not enter the sleep state, and maintains the current active state. That is, in this embodiment, not only the DRX inactivity timer but also the network assistance information is taken into consideration, and whether there is an available beam can be determined based on the network assistance information, and the terminal device can combine the DRX inactivity timer and the network assistance information to perform state switching, thereby improving the power saving effect of the terminal device. As an example, the first time length may be the sum of a processing time length for the terminal device to process the received downlink data and a hybrid automatic repeat request (HARQ) feedback time length, or may be the time length of a downlink DRX retransmission timer.

[0048] In one embodiment, the plurality of timers include a DRX Hybrid Automatic Repeat Request (HARQ) Round Trip Time (RTT) timer and a DRX retransmission timer, the DRX HARQ RTT timer being turned on when the terminal device erroneously decodes a received Physical Downlink Shared Channel (PDSCH); The step of determining an operation of the terminal device based on the network assistance information and the first state parameter includes: maintaining a current inactive state when it is determined, during operation of the DRX HARQ RTT timer, that a duration during which no beam is available within a first period is equal to or greater than a second period based on network assistance information, and not starting a DRX retransmission timer when the DRX HARQ RTT timer times out and is reset; and if, during operation of the DRX HARQ RTT timer, it is determined based on the network assistance information that the duration for which there is no available beam within the first time period is shorter than the second time period, maintaining the current inactive state, and if the DRX HARQ RTT timer times out and is reset, starting a DRX retransmission timer.

[0049] Here, the first period is the sum of the operation period of the DRX HARQ RTT timer and the second period, the start time of the second period is the timeout time of the DRX HARQ RTT timer, and the end time of the second period is the sum of the timeout time and the time length of the DRX retransmission timer. DRX HARQ RTT timer.

[0050] The DRX retransmission timer is drx-RetransmissionTimer, the DRX HARQ round trip time (RTT) timer is drx-HARQ-RTT-Timer, and the DRX-HARQ-RTT-Timer is turned on when the PDSCH is decoded in error. For example, the downlink drx-HARQ-RTT-Timer may be understood in a physical sense as the retransmission scheduling of the downlink process is scheduled after the timer, and the scheduling window is within the drx-RetransmissionTimerDL (downlink DRX retransmission timer). During the operation of the timer-drx-HARQ-RTT-TimerDL, in combination with the network assistance information sent from the network device, if it detects that there is no available beam and the duration of no available beam nonB2 is equal to or greater than K2, the DRX HARQ RTT timer maintains the current sleep state, the timer is reset, and the drx-RetransmissionTimerDL is not started. That is, in this embodiment, not only the DRX HARQ RTT timer but also the network assistance information is taken into consideration, and whether or not there is an available beam can be determined based on the network assistance information, and the terminal device can combine the DRX HARQ RTT timer and the network assistance information to switch states, thereby improving the power saving effect of the terminal device. As an example, the second time length may be the sum of the time length of the DRX HARQ RTT timer and the time length of the DRX retransmission timer.

[0051] In one embodiment, the step of determining an operation of the terminal device based on the network assistance information and the first state parameter includes: entering an inactive state if, during operation of the DRX retransmission timer, it is determined based on network assistance information that no beam is available during the operation period of the DRX retransmission timer; entering an inactive state if, during operation of the DRX retransmission timer, it is determined based on the network assistance information that a duration during which there is no available beam in the operation period of the DRX retransmission timer is shorter than a time length of the DRX retransmission timer and longer than a third time length, and entering an active state if the duration during which there is no available beam in the operation period of the DRX retransmission timer has expired; maintaining the current active state when, during operation of the DRX retransmission timer, it is determined based on network assistance information that the duration during which there is no available beam during the operation period of the DRX retransmission timer is equal to or less than a third time period.

[0052] As shown in FIG. 3, the drx-RetransmissionTimerDL is turned on after the drx-HARQ-RTT-TimerDL is timed out, and the drx-HARQ-RTT-TimerDL is turned on after the transmission of the PDSCH (Physical Downlink Shared Channel) HARQ-ACK (Hybrid Automatic Repeat request ACK) feedback completes the last symbol, and each downlink process corresponds to one drx-HARQ-RTT-TimerDL / drx-RetransmissionTimerDL. During the operation of the drx-RetransmissionTimerDL, in combination with the network assistance information sent from the network device, if it detects that there is no available beam, it goes into a sleep state in advance. In the middle of the drx-RetransmissionTimerDL operation, if the duration length nonB3 of no available beam is equal to or greater than K3, it goes into a sleep state, the timer is not reset, and it continues to operate and is woken up after the end of nonB3, and enters the active state. In the middle of the operation of drx-RetransmissionTimerDL, if the duration length nonB3 during which there is no available beam is smaller than k3, the device does not enter the sleep state and maintains the current active state. That is, in this embodiment, not only the DRX retransmission timer but also the network assistance information is taken into consideration, and it is possible to determine whether there is an available beam based on the network assistance information, and the terminal device can combine the DRX retransmission timer and the network assistance information to perform state switching and improve the power saving effect of the terminal device. As an example, the third time length is the sum of the processing time length for the previous terminal device to process the received downlink data and the hybrid automatic repeat request (HARQ) feedback time length.

[0053] In one embodiment, the plurality of timers further includes a first timer, the first timer being turned on after the terminal device sends a schedule request (SR); The step of determining an operation of the terminal device based on the network assistance information and the first state parameter includes: entering an inactive state if, during operation of the first timer, it is determined based on the network assistance information that no beam is available during the operation period of the first timer; controlling the terminal device to enter an inactive state when it is determined during operation of the first timer based on the network assistance information that a duration during which there is no available beam in the operation period of the first timer is shorter than the time length of the first timer and longer than a fourth time length, and to enter an active state when the duration during which there is no available beam in the operation period of the first timer has expired; and maintaining the current active state when, during operation of the first timer, it is determined based on network assistance information that the duration during which there is no available beam during the operation period of the first timer is equal to or less than a fourth time period.

[0054] As shown in FIG. 4, DCI refers to Downlink Control Information, that is, downlink control information. After a scheduling request (SR) is transmitted, before receiving new uplink data scheduling, the SR is in Pending state, and this period also belongs to Active Time. If the duration nonB4 of no available beam during the middle of the operation of the first timer is equal to or greater than K4, the timer goes into a sleep state, the timer is not reset, continues to operate, and is woken up after the end of nonB4, and goes into an active state. If the duration nonB4 of no available beam during the middle of the operation of the first timer is smaller than K, the timer does not go into a sleep state and maintains the current active state. That is, in this embodiment, not only the first timer but also the network assistance information is taken into consideration, and it is possible to determine whether there is an available beam based on the network assistance information, and the terminal device can combine the first timer and the network assistance information to switch states, thereby improving the power saving effect of the terminal device. As an example, the fourth time length is the time length from the transmission of the target schedule request to the reception of uplink scheduling corresponding to the target schedule request.

[0055] In one embodiment, the method comprises: The terminal device calculates a paging timing corresponding to the terminal device based on the paging parameters; The method further includes a step of: if it is determined based on the network assistance information that the duration length during which there is no available beam at the paging timing corresponding to the terminal device is shorter than the time length of one paging timing, the terminal device remains in an active state and receives the paging message; or, if it is determined that the duration length during which there is no available beam at the paging timing corresponding to the terminal device is equal to or longer than the time length of one paging timing, the terminal device enters an inactive state and stops receiving the paging message.

[0056] That is, in this embodiment, the duration length during which there is no available beam at the paging timing corresponding to the terminal device, determined by the network auxiliary information, is compared with the time length of one paging timing, and the state is switched based on the comparison result, that is, if the duration length during which there is no available beam at the paging timing corresponding to the terminal device is shorter than the time length of one paging timing, the terminal device maintains an active state and receives a paging message, or if it is determined that the duration length during which there is no available beam at the paging timing corresponding to the terminal device is equal to or longer than the time length of one paging timing, the terminal device enters an inactive state and stops receiving paging messages, thus improving the power saving effect of the terminal device.

[0057] Referring to FIG. 5, FIG. 5 is a flowchart of an information transmission method provided by an embodiment of the present disclosure, which is performed by a network device, and includes the following steps 501-502.

[0058] Step 501: Determine a first state parameter based on a service characteristic of a terminal device.

[0059] Step 502: Send network assistance information and a first state parameter to a terminal device.

[0060] In one embodiment, the network assistance information comprises: Location information for non-terrestrial networks, Orbit information for non-terrestrial networks, beam information of a non-terrestrial network, and the beam information of the non-terrestrial network includes at least one of Antenna gain information for non-terrestrial networks at a specified time; Antenna gain information of non-terrestrial networks at a specified location; and antenna gain information of the ground-based network at the non-specified lowest point distance.

[0061] In one embodiment, the step of transmitting the network assistance information and the first state parameter to the terminal device comprises: sending a system message and / or dedicated signaling including network assistance information to a terminal device; and transmitting a system message and / or dedicated signaling including the network assistance information to the terminal device a number of times.

[0062] In one embodiment, the step of transmitting network assistance information to the terminal device comprises: sending a short message to a terminal device, the short message including a first identifier indicating whether there is information related to a non-terrestrial network, the first identifier being used by the terminal device to obtain network assistance information based on the first identifier; broadcasting a plurality of first association relations including a segment of network assistance information to a terminal device through a system message, the first association relations being used by the terminal device to obtain the network assistance information based on the association relations; and broadcasting the SIB including the first field to the terminal device, wherein the information indicated by the first field is determined by the terminal device based on the information indicated by the first field. the SIB contains network aiding information or does not contain network aiding information; Whether the network auxiliary information contained in the SIB is complete or partial; The location of the segment of network assistance information included in the SIB in the network assistance information; whether the network assistance information segment contained in the SIB is followed by a related network assistance information segment; The SIB is used to determine at least one of: that it is the last SIB containing ephemeris information; or that it is not the last SIB containing ephemeris information.

[0063] The process of the above method is specifically described below by a specific example.

[0064] With the continuous development of satellite antenna technology, most of the current wide satellite systems use multi-spot beam satellites to improve the system capacity, and the current multi-spot beam satellite communication system designs the frequency multiplexing of each beam in the load, and the radio frequency power has no fixed allocation method. Multi-beam antenna technology, as one of the essential technologies for wideband satellite communication systems, has been widely applied in many actual satellite communication systems. The traditional multi-beam satellite allocates the bandwidth and power evenly to each spot beam, but the allocation and needs of the ground service are uneven, so the resource utilization rate of the satellite system is low and the actual communication capacity is greatly reduced. In order to solve the problem of the mismatch between the satellite resource needs and the configuration, beam hopping (beam hopping, BH) has been developed on the basis of the traditional multi-beam, as shown in Figure 6 and Figure 7. The flexible allocation method of allocating the entire satellite bandwidth to the beams in units of time slots can better meet the needs of different services of each beam. Satellite beam hopping technology can allocate resources in four dimensions: space, time, frequency and power, and has shown excellent applicability in high-throughput satellite systems due to its excellent flexibility, resource utilization efficiency and ability to dynamically change according to ground services. In Figure 6, LEO is low-earth orbit satellite and Unit is unit.

[0065] Regarding the DRX cycle, as shown in Fig. 8, the terminal device is awake during the active period (on duration) and is in a sleep state during the sleep period (opportunity for DRX). The terminal device in the sleep state can receive not only the PDCCH but also data of other physical channels, for example, PDSCH and ACK / NACK.

[0066] A network device notifies a terminal device of DRX parameters through RRCconnectionReconfig (RRC connection setup signaling) and may also notify through RRCconnectionSetup (RRC connection establishment) signaling. Some basic timers are described as follows: 1) onDurationTimer: the number of PDCCH subframes to be continuously monitored from the start of one DRX cycle. 2) drx-InactivityTimer: the number of consecutive PDCCH subframes that the terminal remains in the active state after successfully decoding one PDCCH indicating the first transmitted uplink downlink data. 3) drx-RetransmissionTimer: the number of PDCCH subframes to be continuously monitored from the subframe where the terminal expects to receive a downlink retransmission. 4) longDRX-CycleStartoffset: specifies longDRX-cycle and drxstartffset. 5) shortDRX-cycle: the number of consecutive subframes of a shortDRX cycle. 6) drxShortCycleTimer: Specifies how long the terminal uses the short DRX cycle. The value is a multiple of the short DRX cycle.

[0067] This application mainly provides a DRX function operation performed using satellite beam hopping, and takes the case where the network device is a satellite base station as an example.

[0068] First, the satellite base station 1 determines for one terminal device (UE) (or one or more services of one UE) to use beam information at different times, for example, in a multi-beam satellite system, a beamforming antenna generates K point beams in a coverage area, and the total bandwidth is Mtotal, and a satellite using BH technology allocates the system total bandwidth to each point beam in slot units, for example, a time window with a slot length of P1, and the minimum slot allocation unit is Slot, and the system allocates a corresponding number of slots according to the needs and current load conditions of different services of each beam, that is, the service of the UE is allocated m+k slots within the length of P1, and is a beam at m slots and b beam at k slots, or the co-covering satellite base station 2 determines the beam information for one UE (or one or more services of one UE) to use at different times.

[0069] Prior to this, in a scenario where spectrum is shared between a mobile network and a satellite network, the two types of base stations may negotiate the format between point beams in advance, and the point beam patterns (images) on both sides may be orthogonal. In another aspect, due to the mobility of the UE, it is necessary to introduce a dynamic beam pattern orthogonal solution. Since the two networks are interoperated between operators, dynamic interaction between the networks becomes difficult. Therefore, the UE can simultaneously receive signals from two network devices, and when it is found that the network device 1 transmits a point beam other than a static pattern, it notifies the network device 2 through Medium Access Control (MAC) / DCI signaling and carries power value information, and the network device 2 determines whether to modify the transmission of the point beam according to the report from the UE. In addition, the satellite base station can allocate slots corresponding to point beams based on the service needs of terminal devices within its coverage and the current load situation of the base station, and transmit point beam information covering the UE to the UE, i.e., the point beam information includes a point beam sequence and slots allocated for the point beam sequence, and the slots of the point beam sequence are allocated by the satellite base station based on the service needs of terminals covered by the multiple point beams of the network device and the current load situation of the network device.

[0070] Then, the satellite base station 1 determines the DRX parameters based on the service characteristics of the UE.

[0071] The satellite base station 1 may transmit the determined beam information and DRX parameters to the terminal device UE, and in this application, the state in which the UE does not monitor PDCCH scheduling is called a sleep state, and the opposite is called an active state.

[0072] The terminal device improves the power saving effect by determining the state of the terminal device based on the transmitted point beam information and DRX parameters, i.e., by using the beam hopping usage information and DRX parameters, in combination with the redesigned DRX function and the use of a UE-side timer, the terminal device determines the state of the terminal device to improve the power saving effect.
