Description

Cross-reference to Related Applications

[0001] This application claims the priority of Chinese Patent Application No. 202111666582.3 filed in China on December 31, 2021, the entire content of which is incorporated herein by reference.

Technical Field

[0002] This disclosure relates to the field of communication technologies, and particularly to an operation decision method, an information transmission method, a terminal device, and a network device.

Background Art

[0003] In the discontinuous reception (DRX) mode, the terminal device does not continuously monitor the physical downlink control channel (PDCCH), but monitors it periodically. That is, in the DRX mode, the DRX cycle includes an active period and an inactive period. In the active period, the terminal device monitors the PDCCH, and in the inactive period, it does not monitor the PDCCH. In this way, it is possible to avoid the terminal device from continuously monitoring, thereby achieving the purpose of power saving.

[0004] However, in the process of communication between the terminal device and the network device, it is necessary for the network to transmit data. However, it is easy for the terminal device to have no network coverage in the active period, and it is impossible to achieve effective monitoring even when entering the active period, so power waste is likely to occur. That is, the power saving effect of the terminal device in the DRX mode is poor.

[0025] Referring to Figure 1, Figure 1 is a flowchart of an operation determination method provided by an embodiment of the present disclosure, the method being performed by a terminal device, the method comprising the following steps 101-102.

[0026] Step 101: Receive network auxiliary information and first state parameters sent from the network device.

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

[0028] Network auxiliary information may be used to determine the network coverage status corresponding to the terminal device, and the first state parameter may be understood as a parameter that affects the terminal device state. Network devices transmit network auxiliary information and the first state parameter to other network devices, and after the terminal device receives the network auxiliary information and the first state parameter, it can decide on an operation for the terminal device based on the network auxiliary information and the first state parameter. Deciding on an operation for the terminal device may mean deciding for the terminal device to enter a specific state.

[0029] In one example, the first state parameter is determined based on the service characteristics of the terminal device, and the first state parameter is, Discontinuous reception DRX parameters, Includes at least one of the paging parameters.

[0030] In this embodiment, in the process of determining the operation of the terminal device, not only the first state parameter but also network auxiliary information transmitted by the network device is considered, and the operation of the terminal device is determined by combining the network auxiliary information and the first state parameter, thereby improving the accuracy of determining the operation of the terminal device, and since the operation of the terminal device affects the amount of electricity consumed by the terminal device, the power saving effect of the terminal device can be improved.

[0031] In one embodiment, network auxiliary information is Location information of at least one non-terrestrial network, Orbital information of at least one non-terrestrial network, The beam information of at least one non-terrestrial network, which includes at least one of the beam information of at least one non-terrestrial network, Antenna gain information of at least one non-terrestrial network at a specified time, Antenna gain information of at least one non-terrestrial network at a specified location, It includes at least one of the following: antenna gain information of at least one non-terrestrial network at a distance to a specified minimum point.

[0032] Network auxiliary information is, The validity period and / or update cycle of location information for at least one non-terrestrial network, The validity period and / or update cycle of orbital information for at least one non-terrestrial network, The at least one of the validity period and / or update cycle of beam information for at least one non-terrestrial network is further included.

[0033] The location information of the non-terrestrial network (e.g., satellite) may be satellite position coordinate information such as longitude, latitude, height, and / or angle, or it may be first, second, and / or third time derivative information of the satellite's motion. The orbital information may be temporary or average orbital information. The terminal device can use the location information of the non-terrestrial network and the location information of the terminal device itself to estimate the effective coverage of the terminal device by the satellite, that is, to determine the coverage status, and the effective coverage can be determined by at least one of the following pieces of information: when the satellite starts providing coverage to the terminal device, when the satellite stops providing coverage to the terminal device, the time period during which the satellite provides coverage to the terminal device, and the time period during which the satellite cannot provide coverage to the terminal device. The effective coverage of the satellite to the terminal device can be determined using beam information of the non-terrestrial network, and furthermore, the effective coverage of the satellite to the terminal device can be determined more accurately based on the antenna gain of the beam.

[0034] In one embodiment, the step of receiving network auxiliary information transmitted from a network device is: The steps include receiving system messages and / or dedicated signaling transmitted from a non-terrestrial network node and / or other network nodes, and reading network auxiliary information from the system messages and / or dedicated signaling, The process includes at least one of the following steps: receiving multiple system messages and / or dedicated signaling transmitted from a non-terrestrial network node and / or other network node, and reading network auxiliary information from the system messages and / or dedicated signaling.

[0035] Note that "other network nodes" may refer to network nodes other than non-terrestrial network nodes. Furthermore, the above network device may be a non-terrestrial network node and / or other network nodes, and if 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 nodes may transmit information from different satellites in batches at different times.

[0036] In one embodiment, the steps of receiving system messages and / or dedicated signaling transmitted from a non-terrestrial network node and / or other network nodes, and reading network auxiliary information from the system messages and / or dedicated signaling, The terminal device combines system messages and / or dedicated signaling transmitted from a non-terrestrial network node and / or other network nodes to obtain first combination information, and reads network auxiliary information from the first combination information. The process includes at least one of the following steps: a terminal device combines system messages and / or dedicated signaling transmitted from multiple non-terrestrial network nodes to obtain second combination information, and reading network auxiliary information from the second combination information.

[0037] For example, a terminal device obtains a first part of ephemeris information from satellite network node 1, then obtains a second part of ephemeris information from satellite network node 2, and combines them to obtain the necessary or complete ephemeris information. Alternatively, the terminal device needs to obtain the first part of the ephemeris information from satellite network node 1, and the second part of the ephemeris information and the third part of the ephemeris information from satellite network node 2 and satellite network node 3, respectively, and then combine them to obtain the necessary or complete ephemeris information. Alternatively, the terminal device needs to obtain the first part of the ephemeris information from satellite network node 1, and the second and third parts of the ephemeris information from satellite network node 2 and satellite network node 3 during the T2 and T3 time zones, respectively, and then combine them to obtain the necessary or complete ephemeris information. Alternatively, the terminal device must obtain the first part of the ephemeris information from satellite network node 1, and then subsequently obtain the second part of the ephemeris information and the third part of the ephemeris information from the SIBx (system message x) and SIBy (system message y) of satellite network node 2, and the SIBx of satellite network node 3, respectively, and combine them to obtain the necessary or complete ephemeris information. Alternatively, the terminal device obtains information for one transmission cycle necessary to obtain the required or complete ephemeris information from satellite network node 1, transmits the starting position information, and the terminal device obtains the first part of the ephemeris information, the second part of the ephemeris information, and the third part of the ephemeris information in the T1, T2, and T3 time periods, respectively, and combines them to obtain the required or complete ephemeris information. Alternatively, the terminal device obtains information for one transmission cycle necessary to obtain the required or complete ephemeris information from satellite network node 1, transmits the starting position information, and the terminal device can obtain the first part of the ephemeris information, the second part of the ephemeris information, and the third part of the ephemeris information from SIBx, SIBy, and SIBz in the T1, T2, and T3 time zones, respectively, and combines them to obtain the required or complete ephemeris information. Alternatively, the terminal device obtains information for one transmission cycle necessary to obtain the required or complete ephemeris information from satellite network node 1, transmits information for 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 SIBx during the T1, T2, and T3 time periods, and combine them to obtain the required or complete ephemeris information.

[0038] Furthermore, the above methods may be used in combination in part or in combination in all form.

[0039] The above information can be communicated to terminal devices via non-terrestrial networks, terrestrial networks, and / or core networks.

[0040] Due to the large size of ephemeris information, when the memory of non-terrestrial network nodes is limited or the size of the signaling that can be transmitted is limited, multiple network nodes transmit the information, and terminal devices combine it to obtain more auxiliary information such as satellite positions and beams.

[0041] In one embodiment, the steps of receiving system messages and / or dedicated signaling transmitted from a non-terrestrial network node and / or other network nodes multiple times, and reading network auxiliary information from the system messages and / or dedicated signaling, are as follows: The terminal device receives multiple system messages and / or dedicated signaling transmitted from a non-terrestrial network node, combines them to obtain third combined information, and reads network auxiliary information from the third combined information. The terminal device transmits system messages and / or dedicated signaling sent from other network nodes multiple times, combines them to obtain fourth combination information, and reads network auxiliary information from the fourth combination information. The terminal device includes at least one of the following steps: receiving system messages and / or dedicated signaling transmitted from a non-terrestrial network node and other network nodes multiple times, combining them to obtain fifth combined information, and reading network auxiliary information from the fifth combined information.

[0042] In other words, in this embodiment, network nodes transmit information from different satellites in batches at different times, and terminal devices combine this information to obtain auxiliary information such as the positions and beams of more satellites.

[0043] In one embodiment, a short message is received from a network device, and the short message includes a first identifier indicating whether or not there is information related to a non-terrestrial network, where the terminal device obtains network auxiliary information based on the first identifier. A network device receives multiple first associations, each containing a system message for a segment of network auxiliary information, which the network device has broadcast in a system message; a terminal device obtains network auxiliary information based on the first associations, where the first associations include a number and / or sequence indicating a system message for at least one segment of network auxiliary information; Multiple network devices have received a second association that includes a system message containing at least one segment of network auxiliary information broadcast in a system message. A network device receives a broadcasted SIB, and the SIB contains a first field, where the terminal device, based on the information indicated by the first field, The SIB may or may not contain network auxiliary information. Is the network support information included in the SIB complete or incomplete? In network auxiliary information, the location of the network auxiliary information segment included in the SIB. The network auxiliary information segment included in the SIB may then determine whether or not there are related network auxiliary information segments. The SIB determines at least one of the following: it is the last SIB containing ephemeris information, or it is not the last SIB containing ephemeris information. Here, the second related relationship is: Other network device information that carries the location of the network auxiliary information segment, Number of segments of network auxiliary information, Number of satellites and / or satellite information, The SIB number where the network auxiliary information segment is located includes at least one of the following: Here, the terminal device obtains network auxiliary information based on the second association.

[0044] A short message may include a first identifier, which can indicate network auxiliary information, and a terminal device can obtain the network auxiliary information based on the indication of the first identifier. A broadcast association is an association of multiple SIBs, where each SIB contains some network auxiliary information, and a terminal device can obtain the network auxiliary information based on the association. A network device may also receive a broadcasted SIB, which may include a first field, for example, a sib-Seg field, and the terminal device can obtain the information indicated by the field. Whether or not the SIB contains network support information, Whether the network support information included in the SIB is complete or incomplete, The location of some of the network auxiliary information included in the SIB in the network auxiliary information, The network auxiliary information segment included in the SIB may then determine whether or not there are related network auxiliary information segments. The SIB can be determined to be either the last SIB containing ephemeris information or not the last SIB containing ephemeris information. For example, setting this to true indicates that there are related SIBs that broadcast ephemeris information after this one, while setting it to false indicates that this is the last SIB containing ephemeris information.

[0045] Specifically, for example, by adding a new identifier to a Short Message, it indicates whether or not there is satellite information, and the terminal retrieves the relevant ephemeris information based on the instructions from that identifier. The network node broadcasts the relationships between multiple informational messages, including ephemeris information, in the system information, and the terminal device retrieves the relevant ephemeris information based on these relationships. A field (e.g., sib-Seg) is added to system messages containing ephemeris information. Setting this field to true indicates that there will be other SIBs broadcasting ephemeris information later, while setting it to false indicates that this is the last SIB containing ephemeris information.

[0046] In one embodiment, the DRX parameter includes the duration of multiple timers of the DRX, the multiple timers include a DRX inactive timer, the DRX inactive timer is turned on when a terminal device receives a physical downlink control channel (PDCCH) and the PDCCH instructs a new data transmission. The step of determining the operation of a terminal device based on network auxiliary information and a first state parameter is: During the operation of the DRX inactive timer, if it is determined, based on network auxiliary information, that there are no beams available during the DRX inactive timer's operating period, the step is to enter an inactive state. During the operation of the DRX inactive timer, if, based on network auxiliary information, it is determined that the duration for which there are no available beams during the DRX inactive timer's operating period is less than the DRX inactive timer's duration and longer than a first duration, the terminal device enters an inactive state. If the duration for which there are no available beams during the DRX inactive timer's operating period ends, the device enters an active state. The procedure includes one of the following steps: during the operation of the DRX inactive timer, if it is determined, based on network auxiliary information, that the duration for which there are no available beams during the DRX inactive timer's operating period is less than or equal to a first duration, maintain the current active state.

[0047] As shown in Figure 2, the DRX Inactivity Timer, or drx-InactivityTimer, turns on when it receives a Physical Downlink Control Channel (PDCCH) and indicates that it is a new data transmission. When it times out, it enters a sleep state (inactive state). During drx-InactivityTimer operation, if it detects that there are no available beams in combination with network auxiliary information transmitted from network devices, it enters a sleep state in advance. In the middle of drx-InactivityTimer operation, if the duration of no available beams (nonB1) is greater than or equal to the first time length k1, it enters a sleep state, the timer is not reset, and it continues to operate. After nonB1 ends, it wakes up and enters an active state. In the middle of drx-InactivityTimer operation, if the duration of no available beams (nonB1) is less than k1, it does not enter a sleep state and maintains its current active state. In other words, in this embodiment, not only the DRX inactive timer but also network auxiliary information is considered, and it is possible to determine whether or not there is an available beam based on the network auxiliary information. The terminal device can perform state switching by combining the DRX inactive timer and network auxiliary information, thereby improving the power saving effect of the terminal device. As an example, the first time length may be the sum of the processing time length for the terminal device to process the received downlink data and the Hybrid Automatic Retransmission Request (HARQ) feedback time length, or it may be the time length of the downlink DRX retransmission timer.

[0048] In one embodiment, the 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 if the terminal device incorrectly decodes the received Physical Downlink Shared Channel (PDSCH), The step of determining the operation of a terminal device based on network auxiliary information and a first state parameter is: During the operation of the DRX HARQ RTT timer, if it is determined, based on network auxiliary information, that the duration for which there are no available beams within the first period is greater than or equal to the second duration, the current inactive state is maintained, and if the DRX HARQ RTT timer times out and is reset, the DRX retransmission timer is not started. The DRX HARQ RTT timer includes the step of maintaining its current inactive state if, during operation, it is determined based on network auxiliary information that the duration for which no beams are available within a first period is shorter than a second time length, and activating the DRX retransmission timer if the DRX HARQ RTT timer times out and is reset.

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

[0050] The DRX retransmission timer is drx-RetransmissionTimer, and the DRX HARQ round-trip time (RTT) timer is drx-RetransmissionTimer, and the DRX-HARQ-RTT-Timer is drx-RetransmissionTimer, which turns on if the PDSCH is misdecoded. For example, the downlink drx-HARQ-RTT-Timer may be understood in a physical sense as the retransmission scheduling of the downlink process being scheduled after the timer, and the scheduling window being within drx-RetransmissionTimerDL (downlink DRX retransmission timer). During the operation of timer-drx-HARQ-RTT-TimerDL, in combination with network auxiliary information sent from the network device, if it is detected that there are no available beams and the duration of no available beams nonB2 is K2 or greater, the DRX HARQ RTT timer maintains its current sleep state, the timer is reset, and drx-RetransmissionTimerDL is not invoked. In other words, in this embodiment, not only the DRX HARQ RTT timer but also network auxiliary information is considered, and it is possible to determine whether or not there is an available beam based on the network auxiliary information. The terminal device can perform state switching by combining the DRX HARQ RTT timer and network auxiliary information, 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 the operation of a terminal device based on network auxiliary information and a first state parameter is: During the operation of the DRX retransmission timer, if it is determined, based on network auxiliary information, that there are no beams available during the DRX retransmission timer's operating period, the timer enters an inactive state. During the operation of the DRX retransmission timer, if, based on network auxiliary information, it is determined that the duration for which no beams are available during the DRX retransmission timer's operating period is less than the DRX retransmission timer's duration and longer than the third duration, the timer enters an inactive state. If the duration for which no beams are available during the DRX retransmission timer's operating period ends, the timer enters an active state. The DRX retransmission timer includes one of the following steps: if, during operation of the DRX retransmission timer, it is determined, based on network auxiliary information, that the duration for which there are no available beams during the DRX retransmission timer's operating period is less than or equal to three hours, maintain the current active state.

[0052] As shown in Figure 3, the drx-RetransmissionTimerDL turns on after the drx-HARQ-RTT-TimerDL times out, and the drx-HARQ-RTT-TimerDL turns on after the transmission of PDSCH (Physical Downlink Shared Channel) HARQ-ACK (Hybrid Automatic Repeat request ACK) feedback completes the last symbol, with each downlink process corresponding to one drx-HARQ-RTT-TimerDL / drx-RetransmissionTimerDL. During the operation of the drx-RetransmissionTimerDL, if it detects that there are no available beams in combination with network auxiliary information sent from the network device, it enters a sleep state beforehand. In the middle of the operation of the drx-RetransmissionTimerDL, if the duration of no available beams (nonB3) is K3 or longer, it enters a sleep state, the timer is not reset, and it continues to operate until it wakes up after nonB3 ends and enters the active state. During the mid-term operation of drx-RetransmissionTimerDL, if the duration nonB3 (when no beam is available) is less than k3, the device does not enter sleep mode and maintains its current active state. In other words, in this embodiment, not only the DRX retransmission timer but also network auxiliary information is considered, and the presence or absence of an available beam can be determined based on the network auxiliary information. The terminal device can then switch states by combining the DRX retransmission timer and network auxiliary information, thereby improving the power saving effect of the terminal device. As an example, the third time length is the sum of the processing time for the downlink data received by the previous terminal device and the Hybrid Automatic Retransmission Request (HARQ) feedback time.

[0053] In one embodiment, the plurality of timers further include a first timer, which is turned on after a terminal device sends a schedule request (SR). The step of determining the operation of a terminal device based on network auxiliary information and a first state parameter is: During the operation of the first timer, if it is determined, based on network auxiliary information, that there are no beams available during the operating period of the first timer, the timer enters an inactive state. During the operation of the first timer, if, based on network auxiliary information, it is determined that the duration for which there are no available beams during the operation period of the first timer is shorter than the duration of the first timer and longer than the fourth duration, the terminal device is controlled to enter an inactive state, and when the duration for which there are no available beams during the operation period of the first timer ends, the device enters an active state. The operation of the first timer includes one of the following steps: if, during the operation of the first timer, it is determined based on network auxiliary information that the duration for which there are no available beams during the operation period of the first timer is less than or equal to the fourth duration, maintain the current active state.

[0054] As shown in Figure 4, DCI refers to Downlink Control Information, which is downlink control information. After a scheduling request (SR) is sent, and before a new uplink data scheduling is received, the SR is in a pending state. This period also belongs to the Active Time. If, during the middle of the operation of the first timer, the duration nonB4 (the period during which no beams are available) is K4 or greater, the device enters a sleep state. The timer is not reset and continues to operate, waking up after nonB4 ends and entering the active state. If, during the middle of the operation of the first timer, the duration nonB4 (the period during which no beams are available) is less than K, the device does not enter a sleep state and maintains its current active state. In other words, in this embodiment, not only the first timer but also network auxiliary information is considered, and it is possible to determine whether or not there are available beams based on the network auxiliary information. The terminal device can combine the first timer and network auxiliary information to switch states and improve the power saving effect of the terminal device. As an example, the fourth time length is the time from when the terminal device sends a target scheduling request until when it receives the uplink scheduling corresponding to the target scheduling request.

[0055] In one embodiment, the method is: The terminal device calculates the corresponding paging timing based on the paging parameters, The further steps include: if, based on network auxiliary information, it is determined that the duration for which there are no available beams for a paging timing corresponding to the terminal device is shorter than the duration of one paging timing, the terminal device remains active and receives paging messages; or if it is determined that the duration for which there are no available beams for a paging timing corresponding to the terminal device is longer than or equal to the duration of one paging timing, the terminal device enters an inactive state and stops receiving paging messages.

[0056] In other words, in this embodiment, the duration for which there are no available beams for the paging timing corresponding to the terminal device, as determined by network auxiliary information, is compared with the duration of one paging timing, and the state is switched based on the comparison result. Specifically, if the duration for which there are no available beams for the paging timing corresponding to the terminal device is shorter than the duration of one paging timing, the terminal device remains active and receives paging messages. Alternatively, if it is determined that the duration for which there are no available beams for the paging timing corresponding to the terminal device is greater than or equal to the duration of one paging timing, the terminal device enters an inactive state and stops receiving paging messages. In this way, the power saving effect of the terminal device can be improved.

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

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

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

[0060] In one embodiment, network auxiliary information is Location information of non-terrestrial networks, Orbital information for non-terrestrial networks, The beam information of a non-terrestrial network includes at least one of the following, and the beam information of a non-terrestrial network is Antenna gain information for non-terrestrial networks at a specified time. Antenna gain information for non-terrestrial networks at a specified location. It includes at least one of the following: antenna gain information of a terrestrial network at a distance to an unspecified minimum point.

[0061] In one embodiment, the step of transmitting network auxiliary information and a first state parameter to a terminal device is: The steps include sending a system message and / or dedicated signaling containing network support information to a terminal device, The process includes sending system messages and / or dedicated signaling containing network support information to a terminal device multiple times.

[0062] In one embodiment, the step of sending network auxiliary information to a terminal device is: A step of sending a short message to a terminal device, wherein the short message includes a first identifier indicating whether or not it contains information related to a non-terrestrial network, and the first identifier is used by the terminal device to obtain network auxiliary information based on the first identifier. A step of broadcasting a plurality of first associations, including a system message for a segment of network auxiliary information, to a terminal device via a system message, wherein the first associations are used by the terminal device to obtain network auxiliary information based on the associations. The process further includes one of the following steps: broadcasting an SIB containing a first field to a terminal device, wherein the information indicated by the first field is used by the terminal device based on the information indicated by the first field. The SIB may or may not contain network auxiliary information. Is the network support information included in the SIB complete or incomplete? In network auxiliary information, the location of the network auxiliary information segment included in the SIB. The network auxiliary information segment included in the SIB may then determine whether or not there are related network auxiliary information segments. The SIB is used to determine at least one of the following: 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 will be specifically explained below with reference to one concrete example.

[0064] With the continuous development of satellite antenna technology, most current wideband satellite systems utilize multi-spot beam satellites to improve system capacity. Current multi-spot beam satellite communication systems are designed with frequency multiplexing of each beam under load, and there is no fixed allocation method for radio frequency power. Multi-beam antenna technology is one of the essential technologies for broadband satellite communication systems and is widely applied in many actual satellite communication systems. Conventional multi-beam satellites allocate bandwidth and power equally to each spot beam, but because the allocation and needs of ground services are uneven, the resource utilization rate of the satellite system is low, and the actual communication capacity is significantly reduced. To solve the problem of the mismatch between satellite resource needs and configuration, beam hopping (BH) has developed based on conventional multi-beam, as shown in Figures 6 and 7. The flexible allocation method of allocating the entire satellite bandwidth to beams in time slot units can better meet the different service needs of each beam. Satellite beamhopping technology can allocate resources in four dimensions: space, time, frequency, and power. Its superior flexibility, resource utilization efficiency, and ability to dynamically change in response to ground services make it highly applicable to high-throughput satellite systems. In Figure 6, LEO stands for low-earth orbit satellite, and Unit stands for Unit.

[0065] Regarding the DRX cycle, as shown in Figure 8, terminal devices are activated during the active period (on duration) and are in a sleep state during the sleep period (opportunity for DRX). While in sleep mode, terminal devices do not receive only PDCCH but can receive data from other physical channels, such as PDSCH and ACK / NACK.

[0066] Network devices may notify a terminal device of its DRX parameters through RRCconnectionReconfig (RRC connection setup signaling) and also through RRCconnectionSetup (RRC connection establishment) signaling. Several basic timers are described below: 1) onDurationTimer: The number of PDCCH subframes to monitor continuously from the start of one DRX cycle. 2) drx-InactivityTimer: The number of consecutive PDCCH subframes that the terminal remains active after successfully decoding one PDCCH representing the first transmitted uplink-downlink data. 3) drx-RetransmissionTimer: The number of PDCCH subframes to monitor continuously from the subframe from which the terminal expects to receive a downlink retransmission. 4) longDRX-CycleStartoffset: Specifies longDRX-cycle and drxstartoffset. 5) shortDRX-cycle: The number of consecutive subframes in a shortDRX cycle. 6) drxShortCycleTimer: Specifies how often the terminal will use a short DRX cycle. This value is a multiple of the short DRX cycle.

[0067] This application primarily provides DRX function operations performed using satellite beamhopping, illustrating the case where the network device is a satellite base station as an example.

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

[0069] Prior to this, in scenarios where the spectrum is shared between mobile and satellite networks, the two types of base stations may pre-consult on the format between point beams and orthogonalize the point beam patterns (images) on both sides. In another embodiment, due to the mobility of the UE, a dynamic beam pattern orthogonal solution needs to be introduced. Since the two networks are coordinated between operators, dynamic communication between networks becomes difficult. Therefore, the UE can receive signals from both network devices simultaneously, and when it is determined that network device 1 has transmitted a point beam other than a static pattern, it notifies network device 2 via Medium Access Control (MAC) / DCI signaling and carries power value information, and network device 2 decides whether or not to correct the transmission of the point beam based on the report from the UE. Furthermore, a 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 status of the base station, and transmit point beam information covering the UE to the UE, that is, the point beam information includes a point beam sequence and the slots allocated for the point beam sequence, the slots of the point beam sequence obtained by the satellite base station based on the service needs of terminals covered by multiple point beams of the network device and the current load status of the network device.

[0070] Next, 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. In this application, the state in which the UE does not monitor PDCCH scheduling is referred to as the sleep state, and the opposite state is referred to as the active state.

[0072] The terminal device improves power saving by determining its state based on transmitted point beam information and DRX parameters; specifically, it improves power saving by determining the state of the terminal device using beam hopping usage information and DRX parameters, in combination with the redesigned DRX functionality and the use of timers on the UE side.
