Herein, "a" means not only "only this one" but also "more than one" case.
It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
In addition, in the description of the present application, the terms "first," "second," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following description will explain the specific embodiments of the present invention with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the invention, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.
One of the key points in the NTN technology is that the satellite can inform the current position of the communication terminal in real time in an ephemeris mode, so that the communication terminal can calculate the distance between the satellite and the satellite, and further calculate the transmission delay and Doppler frequency offset of an air interface to realize uplink and downlink communication transmission between the communication terminal and a network. If the communication terminal cannot acquire the latest position of the satellite, especially for a low orbit satellite with a high motion speed, the uplink and downlink transmission of the communication terminal is in high probability of error.
Since the NB-IOT is a half duplex system and the priority of SIB31-NB update is highest, the uplink traffic to be or in progress must be suspended when the communication terminal updates SIB 31-NB. After the SIB31-NB is successfully read, the communication terminal cancels the uplink service before, and all uplink HARQ buffers are emptied, if the base station does not schedule uplink any more, the communication terminal monitors NPDCCH in a connection state until the T-PollRetransmit-NB-r13 timer is overtime, and then the uplink flow can be triggered again. However, because the network side generally configures a larger value for the T-PollRetransmit-NB-r13, the time delay of the uplink service is greatly increased, an intuitive feeling of "cut-off" of the service is provided for the user, and in addition, the communication terminal side needs to monitor NPDCCH all the time before the T-PollRetransmit-NB-r13 timer times out, which greatly wastes the power consumption of the communication terminal.
If the uplink data service is sent continuously after the timeout of T317, the SIB31-NB is deferred to be updated in the next period, the protocol is not in accordance with the R17, the timeout of T317 means the uplink is out of step, and the uplink is not significant from the perspective of the protocol; in addition, the priority of the connection state collection SIB31-NB is lowered, so that a new problem is brought, namely, if the delayed SIB31-NB collides with the subsequent uplink service, the SIB31-NB always avoids uplink data and cannot be updated later, and if the ephemeris taken by the terminal cannot be updated on time, the operation of the whole NTN communication link is affected.
Based on the problems, the application designs a scheme for quickly recovering uplink data after the SIB31-NB is updated by the communication terminal in a connection state according to different scenes, and simultaneously can also consider possible scheduling of the network side after the SIB31-NB is updated by the terminal side, monitor NPDCCH continuously, and realize the effect of not missing any possible network scheduling. In one embodiment of the present application, as shown in fig. 1, the present application provides a non-terrestrial network communication method based on NB-IOT, comprising the steps of:
S200, when a timeout condition exists in the process that the communication terminal receives satellite ephemeris data through system broadcasting, the buffer data of the hybrid automatic repeat request is reserved.
Specifically, in the NB-IOT network, the ephemeris data of the satellite is notified to the UE through the SIB31-NB of the system message added by R17. For the network side, SIB31-NB is broadcast periodically, but for the communication terminal side, a SIB31-NB that has been read successfully has an effective time, where the effective time is configured by a parameter ul-SyncValidityDuration-R17 in SIB31-NB, and the R17 protocol 36.331 defines a T317 timer to manage the effective time, in this embodiment, if T317 times out, it is considered that the connected terminal loses uplink synchronization, i.e., in the existing scheme, the terminal needs to empty uplink hybrid automatic repeat request buffer data (HARQ buffer) at this time, any uplink service cannot be started any more, and the terminal in the connected state must actively receive a new SIB31-NB until SIB31-NB is updated successfully and resumes the uplink synchronization state again.
S300, the communication terminal monitors the physical downlink control channel in a preset buffer waiting period.
Specifically, the communication terminal designs a buffer waiting period after the SIB31-NB is updated successfully, so that the communication terminal continuously monitors the service of the physical downlink control channel (NEW PHYSICAL Downlink Control Channel, NPDCCH) in the period, and does not miss the scheduling situation possibly existing in the network.
S410, when the network scheduling information is monitored in the buffer waiting period, corresponding uplink and downlink data transmission is executed according to the network scheduling information.
S420, when the network scheduling information is not monitored in the buffer waiting period, the communication terminal immediately sends a scheduling request flow.
Specifically, the scheduling request flow is used for requesting to recover uplink data transmission with the base station.
According to the non-ground network communication method based on the NB-IOT, the buffer waiting period is set, so that the communication terminal can monitor network scheduling information continuously in the period, scheduling possibly existing in a network is prevented from being missed, corresponding control schemes are executed in different network environments in a self-adaptive mode, and meanwhile the autonomous activity of the communication terminal is improved.
In some embodiments, the timeout conditions include a first timeout condition in which the communication terminal is about to perform or the ongoing connection state random access procedure is interrupted, a second timeout condition in which the uplink schedule has been received by the communication terminal but the uplink data is not successfully transmitted, and a third timeout condition in which the communication terminal is interrupted in the ongoing uplink data transmission. The application designs the communication scheme aiming at the three overtime conditions, so that the terminal can rapidly schedule according to the terminal side under the overtime conditions.
In some embodiments, when the timeout condition is the first timeout condition or the second timeout condition, the base station does not receive the uplink data packet of the communication terminal, and after the SIB31-NB is successfully updated, the communication terminal immediately re-performs the connection state random access procedure, and when the network scheduling information is monitored in the buffer waiting period, the communication terminal immediately performs the corresponding uplink and downlink data transmission according to the network scheduling information, and cancels the upcoming connection state random access procedure.
Here, a period between the current time and the preset MSG information transmission time may be taken as the buffer waiting period, for example, a period between the current time and the MSG1 transmission time may be taken as the buffer waiting period.
In some embodiments, when the timeout condition is the third timeout condition, since the uplink transmission may be interrupted immediately after the beginning or after a period of time, and the uplink data of the NB-IOT is repeatedly transmitted, the base station may not have decoded the packet of uplink data or may have decoded the packet of uplink data, so that after the terminal succeeds in reading the SIB31-NB, the scheduling behavior of the network cannot be predicted. In order to avoid possible uplink scheduling conflict with the network side, the communication terminal monitors the physical downlink control channel in a buffer waiting period after reading the SIB31-NB, and if the scheduling can be monitored, the communication terminal listens to the scheduling of the network to continue uplink and downlink data transmission. For example, after reading SIB31-NB, the communication terminal actively starts periodicBSR-Timer-r13 Timer and retxBSR-Timer-r13 Timer, and the communication terminal continues to monitor the physical downlink control channel during the running period of periodicBSR-Timer-r13 Timer and retxBSR-Timer-r13 Timer. However, if the scheduling of the network is not monitored all the time, the timers such as periodicBSR-Timer-r13 or retxBSR-Timer-r13 are overtime, the terminal is actively triggered to initiate the scheduling request flow to resume the uplink transmission, so that the condition that the terminal can only wait for the T-PollRetransmit-NB-r13 overtime in a connection state to resume the uplink transmission service is avoided.
In one embodiment, as shown in fig. 2, the non-terrestrial network communication method based on NB-IOT provided by the present application further includes the steps of, before a timeout condition exists in a process of receiving satellite ephemeris data by a communication terminal through system broadcasting in step S200:
S100, the communication terminal reads the SIB31-NB in a service idle period in a preset period before a timeout condition exists, and immediately executes the next satellite ephemeris data receiving period after decoding the SIB31-NB in the service idle period.
Specifically, for the network side, SIB31-NB is periodically broadcast all the time, and deferring to read SIB31-NB may cause the terminal to take old ephemeris and make the communication link possibly fail to work normally, but reading SIB31-NB in advance has no influence on the communication link, the communication terminal starts to attempt to read SIB31-NB in advance in a service idle period in a period of time before the timeout of T317 timer, and since NB-IOT is a half duplex system, this service idle period needs to avoid a period of time of uplink transmission; if the communication terminal successfully decodes the SIB31-NB in the service idle time, namely the ephemeris of the satellite is updated in advance, and immediately restarts the T317, the problem of service interruption caused by overtime of the T317 is avoided.
In one embodiment, as shown in fig. 3, in combination with the above embodiment, the present application takes the first timeout condition and the second timeout condition as scenario a, the third timeout condition as scenario B, and designs a complete non-terrestrial network communication process in combination with the preprocessing process.
In one embodiment, the present application further provides a communication terminal, where the communication terminal includes a processor and a memory, and the processor implements operations performed by the NB-IOT-based non-terrestrial network communication method according to control instructions stored in the memory.
In one embodiment, the present application also provides a storage medium having at least one instruction stored therein, the instruction being loaded and executed by a processor to implement the operations performed by the NB-IOT based non-terrestrial network communication method described above. For example, the storage medium may be read-only memory (ROM), random-access memory (RAM), compact disk read-only (CD-ROM), magnetic tape, floppy disk, optical data storage device, etc.
