[0099] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

[0100] The term “comprising” and any variation thereof in the specification and claims of the present disclosure is intended to cover a non-exclusive inclusion, for example, a process, method, system, product or apparatus that includes a list of steps or units need not be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such processes, methods, products or apparatus. In addition, the use of “and / or” in the specification and claims means at least one of the connected objects, for example, A and / or B means three cases including A alone, B alone, and A and B both.

[0101] In the embodiments of the present disclosure, the word “exemplary” or “for example” is used to mean serving as an example, instance or illustration. Any embodiment or design solution described as “exemplary” or “for example” in the embodiments of the present disclosure should not be interpreted as being more preferred or having more advantages than other embodiments or design solutions. Rather, the word “exemplary” or “for example” is used to present the relevant concept in a specific manner.

[0102] In order to better understand the embodiments of the present disclosure, the following technical points are introduced first:

[0103] I. Single Star Scenario

[0104] Referring to Figure 1, the UE can only store and forward data through a single satellite. Specifically, when the UE-Sat service link is available, the UE and the satellite can send and receive data; when the Sat-ground feeder link is available, the satellite and the ground network node can send and receive data.

[0105] II. Regarding the Store & Forward (S&F) satellite operation mode.

[0106] Referring to Figure 2, in step A, the UE and the satellite exchange signaling / data, but the satellite is not simultaneously connected to the terrestrial network (i.e., the satellite can operate a service link without an active feeder link connection). In step B, a connection is established between the satellite and the terrestrial network to enable communication between them. Therefore, the connection between the satellite and the UE changes from step A to step B, where the satellite connects to the terrestrial network.

[0107] III. Regarding the Multiple Satellites scenario.

[0108] The UE can transmit and receive data via multiple satellites, specifically:

[0109] Case 1: When the service link between the UE and satellite 1 is unavailable, the UE can send and receive data with other satellites x. The service link between the UE and satellite x is available (see Figure 3a).

[0110] Case 2: When there is no available feeder link between satellite 1 and the ground network node, but there is an available feeder link between satellite x and the ground network node, satellite 1 can connect to satellite x via an inter-satellite link (ISL), and then connect to the ground network node via satellite x's feeder link, as shown in Figure 3b.

[0111] Referring to Figure 4, an embodiment of this disclosure provides a communication processing method, the execution subject of which may be a terminal, and the specific steps include:

[0112] Step 41: The terminal receives the first information;

[0113] In some embodiments, the terminal receives system information or dedicated signaling, the system information or dedicated signaling carrying first information.

[0114] For example, the terminal receives first information from the first communication device. In some embodiments, the first communication device may be a network-side device (or a non-terrestrial network node) of a non-terrestrial network, such as a satellite in a single-satellite scenario or a multi-satellite scenario.

[0115] In some embodiments, the first information may also be referred to as network auxiliary information.

[0116] Step 42: The terminal determines whether the service link between the terminal and the first communication device is available based on the first information.

[0117] For example, the first information is a 1-bit indication. A 1-bit indication of "1" indicates that the service link between the terminal and the first communication device is available, and a 1-bit indication of "0" indicates that the service link between the terminal and the first communication device is unavailable.

[0118] In some embodiments, determining whether the service link between the terminal and the first communication device is available includes determining whether the service link between the terminal and the first communication device is available at the current time. For example, determining whether the service link between the terminal and the first communication device is unavailable at the current time, or determining whether the service link between the terminal and the first communication device is available at the current time.

[0119] In some embodiments, determining whether the service link between the terminal and the first communication device is available includes determining whether the service link between the terminal and the first communication device is available after a period of time. For example, determining that the service link between the terminal and the first communication device is unavailable after a period of time (i.e., determining that the service link is about to become unavailable), or determining that the service link between the terminal and the first communication device is available after a period of time. It is understood that the above-mentioned period of time is not specifically limited in this disclosure and can be adjusted according to factors such as network configuration, protocol design, and channel conditions.

[0120] In some embodiments, the first information includes at least one of the following:

[0121] 1) Second information, the second information is used to indicate whether the first communication device supports store and forward (S&F), that is, the second information is used to indicate whether the first communication device supports store and forward, or the second information is used to indicate whether the first communication device does not support store and forward;

[0122] For example, the second information is a 1-bit indication. If the 1-bit indication is "1", it means that the first communication device supports store-and-forward. If the 1-bit indication is "0", it means that the first communication device does not support store-and-forward.

[0123] 2) Third information, the third information is used to indicate whether the store-and-forward function of the first communication device is activated, that is, the third information is used to indicate that the store-and-forward function of the first communication device is activated, or the third information is used to indicate that the store-and-forward function of the first communication device is not activated;

[0124] For example, the third information is a 1-bit indication. If the 1-bit indication is "1", it means that the store-and-forward function of the first communication device is activated. If the 1-bit indication is "0", it means that the store-and-forward function of the first communication device is not activated.

[0125] Understandably, the terminal can directly determine whether the service link between itself and the first communication device is available through third information. This third information indicates the activation status of the first communication device's store-and-forward function, allowing the terminal to know whether the service link can successfully transmit data. If the store-and-forward function is activated, smooth data transmission is guaranteed; conversely, if the store-and-forward function is not activated, it may affect the reliability and stability of the service link.

[0126] 3) Ephemeris information;

[0127] In some embodiments, ephemeris information includes, but is not limited to, satellite orbital parameters and satellite status.

[0128] Understandably, a terminal can typically determine the availability of a service link between itself and the first communication device directly based on ephemeris information. This data is crucial for calculating the location and communication quality of the first communication device. By receiving and processing ephemeris data, the terminal can calculate the precise location of the first communication device in the air, assess the status of the communication link with the first communication device, and thus determine whether the link is available.

[0129] In some embodiments, the first communication device includes, but is not limited to, network-side devices that are not part of a terrestrial network, such as a satellite.

[0130] 4) Track circumference information, i.e., the track circumference information of the first communication device;

[0131] Understandably, a terminal can typically determine the availability of a service link between itself and a first communication device based on the orbital circumference information of that first communication device. This data is used to calculate the location and communication quality of the first communication device. Using the orbital circumference information, the terminal can calculate the precise location of the first communication device in the air, assess the status of the communication link with the first communication device, and thus determine whether the link is available.

[0132] In one implementation, the terminal can determine whether the service link between the terminal and the first communication device is available based on the orbital circumference information of the first communication device and auxiliary information. The auxiliary information includes, but is not limited to, the terminal location, antenna pointing, environmental information, and at least one of the other information in the first information.

[0133] 5) Satellite operational cycle information, such as the time required for a satellite to complete one cycle in orbit;

[0134] Understandably, a terminal can typically determine the availability of its service link with the first communication device (i.e., the satellite) based on satellite orbital information. This data is used to calculate the location and communication quality of the first communication device (i.e., the satellite). Through satellite orbital information, the terminal can calculate the precise location of the first communication device (i.e., the satellite) in the air, assess the status of the communication link with it, and thus determine its availability.

[0135] In one implementation, the terminal can determine whether the service link between the terminal and the first communication device is available based on satellite operating cycle information and auxiliary information. The auxiliary information includes, but is not limited to, at least one of satellite position, terminal position, signal quality, communication status, environmental information, and other information in the first information.

[0136] 6) The effective duration of the service link (SL) between the terminal and the first communication device;

[0137] Understandably, the duration of a service link can vary depending on specific system and environmental conditions. Generally, the duration of a single service link depends on various factors such as signal obstruction, weather conditions, and satellite orbital position. Typically, the duration of a service link can range from a few seconds to several minutes.

[0138] It is understandable that the terminal can directly determine whether the service link between the terminal and the satellite is available based on the effective duration of the service link between the terminal and the first communication device.

[0139] In one implementation, the terminal can determine whether the service link between the terminal and the first communication device is available based on the effective duration of the service link between the terminal and the first communication device and auxiliary information. The auxiliary information includes, but is not limited to, at least one of signal quality, communication status, environmental information, and other information in the first information.

[0140] 7) The service link downtime;

[0141] In some embodiments, the service link downtime refers to the point in time when the service link is interrupted or terminated. This point in time depends on the specific circumstances and can be caused by various factors, such as signal interference, equipment failure, changes in satellite orbital position, etc. Therefore, the service link downtime can refer to the moment when the service link ends or disconnects.

[0142] Understandably, the terminal can directly determine whether the service link between the terminal and the satellite is available based on the service link's downtime.

[0143] In one implementation, the terminal can determine whether the service link between the terminal and the first communication device is available based on the service link downtime and auxiliary information. The auxiliary information includes, but is not limited to, signal quality, environmental information, and at least one of the other information in the first information.

[0144] 8) Satellite sensing information;

[0145] In some embodiments, the sensing information may include, but is not limited to, at least one of the following: satellite position, orbit information, communication status, attitude information, and environmental information.

[0146] In some embodiments, communication status refers to the satellite's operational status, such as whether the connection was successful and the data transmission rate.

[0147] In some embodiments, attitude information refers to at least one of the satellite's position, orientation, attitude, and motion.

[0148] In some embodiments, environmental information includes, but is not limited to, atmospheric pressure, humidity, and temperature.

[0149] Understandably, the terminal can directly determine whether the service link between the terminal and the satellite is available based on the satellite's sensing information.

[0150] In one implementation, the terminal can determine whether the service link between the terminal and the first communication device is available based on the satellite's sensing information and auxiliary information. The auxiliary information includes, but is not limited to, signal quality, environmental information, and at least one of the other information in the first information.

[0151] 9) Fourth information;

[0152] In some embodiments, the fourth information is used to indicate whether there is a communication link between the first communication device and other communication devices (other network-side devices of non-terrestrial networks). For example, the fourth information is used to indicate whether there is an inter-satellite link (ISL), that is, the fourth information is used to indicate that an ISL exists, or the fifth information is used to indicate that an ISL does not exist.

[0153] In some embodiments, the fourth information is used to indicate whether the communication link between the first communication device and other communication devices is available. For example, the fourth information is used to indicate that the inter-satellite link is available, or the fifth information is used to indicate that the inter-satellite link is unavailable.

[0154] For example, the first communication device and other communication devices can be different satellites in a multi-satellite scenario. In this disclosure, the terminal can determine whether the service link between the terminal and the first communication device is available based on the first information received from the first communication device, avoiding the problem of service quality degradation caused by the inability to determine whether the service link is available, enhancing the stability and performance of the communication connection, improving user experience and system efficiency.

[0155] It is understandable that the terminal can directly determine whether the service link between the terminal and the satellite is available based on the fourth information indicating whether there is a communication link between the first communication device and other communication devices (other network-side devices of non-terrestrial networks).

[0156] In one implementation, the terminal can determine whether the service link between the terminal and the first communication device is available based on the fourth information and auxiliary information. The auxiliary information includes, but is not limited to, the satellite's location, signal quality, environmental information, the terminal's status, and at least one of the other information in the first information.

[0157] In one embodiment of this disclosure, the terminal determines whether the service link between the terminal and the first communication device is available based on first information, including:

[0158] Based on the first information, the terminal determines the remaining service time of the service link between the terminal and the first communication device;

[0159] If the remaining service time of the service link is less than or equal to the propagation delay between the terminal and the first communication device (e.g., UE-Sat), the terminal determines that the service link is unavailable (e.g., determines that the service link is about to become unavailable), and the terminal terminates UL data transmission.

[0160] In some embodiments, the remaining service time of a service link refers to the length of time from the current moment that the service link will remain available. This length of time depends on various factors, including signal strength, interference levels, weather conditions, equipment status, and satellite orbital position. Typically, the terminal device can estimate the remaining service time of the service link based on the first information.

[0161] In some embodiments, the remaining service time of a service link may also be referred to as the remaining effective communication duration of the service link.

[0162] In one embodiment of this disclosure, the terminal determines whether the service link between the terminal and the first communication device is available based on first information, including:

[0163] Based on the first information, the terminal determines the service link cessation time between the terminal and the first communication device;

[0164] If the current time reaches the service link's service stop time, the terminal determines that the service link is unavailable (e.g., it determines that the service link is about to become unavailable), and the terminal terminates uplink (UL) data transmission.

[0165] Typically, the terminal device can estimate the downtime of the service link based on the initial information.

[0166] In one embodiment of this disclosure, the method further includes at least one of the following:

[0167] If the service link is determined to be unavailable, the terminal side terminates uplink data transmission;

[0168] If the terminal determines that the service link is unavailable, the terminal may send fifth information to the first communication device. This fifth information is used to notify the first communication device to terminate downlink data transmission and / or to notify the first communication device of the service link's time information. For example, the time information includes remaining service time and / or service termination time. In some embodiments, the fifth information includes at least one of the following:

[0169] 1) The sixth information is used to indicate that the service link between the terminal and the first communication device is disabled; for example, a specific bit value (such as 0 or 1) or a specific command / instruction is used to indicate the stop or disabled status of the service link.

[0170] 2) The remaining service time of the service link;

[0171] 3) The service stop time of the service link.

[0172] For earth-moving cells, the remaining service time or service stop time of a service link is calculated per UE, and each UE reports the remaining service time or service stop time of its UE-specific service link.

[0173] In one embodiment of this disclosure, the terminal receives a first reporting configuration sent by a first communication device, the first reporting configuration being used to configure the terminal to report fifth information.

[0174] In some embodiments, the first reporting configuration may also be referred to as the service link status reporting configuration.

[0175] In one embodiment of this disclosure, the method further includes:

[0176] The terminal sends a scheduling request (SR), which includes a seventh piece of information. The seventh piece of information is used to notify the first communication device of the amount of data to be sent in the terminal's buffer.

[0177] For example, the terminal sends a scheduling request to the first communication device.

[0178] In some embodiments, the data to be sent in the buffer area may be data that the terminal has pre-assembled to send. If the service link is available, the terminal immediately performs UL data transmission.

[0179] In some embodiments, the seventh piece of information may be a Buffer Status Reporting (BSR) request.

[0180] In some embodiments, the seventh information includes index information, which corresponds to the data volume range of the buffer status report. For example, different index information corresponds to different data volume ranges of the BSR.

[0181] Table 1:

[0182] When the service link is available, the terminal can directly include the BSR request in the SR. Specifically, the BSR data volume range is predefined (as shown in Table 1), and the SR directly includes the corresponding index information. After receiving it, the first communication device directly configures the transmission resources that can carry the upper limit of the data volume range corresponding to the index information.

[0183] Referring to Table 1, the data range of the BSR corresponding to Index 1 is range 1, and the data range of the BSR corresponding to Index 2 is range 2.

[0184] In one embodiment of this disclosure, the method further includes:

[0185] The terminal receives downlink control information (DCI), which includes an eighth piece of information. The eighth piece of information is used for at least one of the following: scheduling multiple uplink data and / or signaling, and scheduling multiple downlink data and / or signaling.

[0186] In some embodiments, the DCI has a new DCI format that can schedule both uplink and downlink, carrying eighth information corresponding to multiple DL and / or UL data in a Physical Downlink Control Channel (PDCCH).

[0187] In some embodiments, the eighth information may also be referred to as scheduling information.

[0188] In some embodiments, the eighth information may include at least one of the following:

[0189] 1) Resources required for DL ​​and / or UL transmissions, such as the resources required for each DL and / or UL transmission;

[0190] 2) The process step index corresponding to DL and / or UL transmission, for example, the process step index corresponding to each DL and / or UL transmission;

[0191] In some embodiments, an index may be a number or identifier used to uniquely identify, distinguish, or index a specific process step.

[0192] 3) Ninth information, which is used to indicate whether data transmission can be completed within the time when the current service link is available, that is, the ninth information is used to indicate whether data transmission can be completed within the time when the current service link is available, or the ninth information is used to indicate whether data transmission cannot be completed within the time when the current service link is available.

[0193] For example, the ninth information is a 1-bit indication. A 1-bit indication of "1" means that data transmission can be completed within the time when the current service link is available, and a 1-bit indication of "0" means that data transmission cannot be completed within the time when the current service link is available.

[0194] 4) Termination of transmission instruction.

[0195] For example, the termination indication is a 1-bit indication, where "1" indicates termination of transmission.

[0196] Referring to Figure 6, one embodiment: for example, for a random access procedure, the specific steps are as follows:

[0197] Step 1: The terminal sends a preamble on the Random Access (RA) resources configured on the first communication device;

[0198] Step 2: After receiving the preamble sent by the terminal, the first communication device directly includes the scheduling information of message 2 (msg2), message 3 (msg3), or message 4 (msg4) in a Physical Downlink Control Channel (PDCCH). The scheduling information corresponding to msg3 includes termination transmission information, indicating that msg3 is the last message that can be transmitted within the available time of this service link, and suspends this random access information.

[0199] Step 3: The terminal receives the scheduling information sent by the first communication device, receives or sends data on the corresponding resource, and knows through the information termination transmission indication that the current RA can only complete the transmission of msg3. Then the terminal suspends this random access information and continues to execute the transmission of msg4 when the service link becomes available again.

[0200] In this disclosure, the terminal can determine whether the service link between the terminal and the first communication device is available based on the first information received from the first communication device. This allows the terminal to notify the system to react quickly and take timely measures to reduce potential delays when it determines that the service link is unavailable. Secondly, in the event of a service link unavailable, the terminal can stop transmitting data or notify the first communication device to terminate downlink data transmission and / or notify the first communication device of the service link's time information, avoiding accidental data loss or transmission errors during transmission. Thirdly, the terminal's ability to promptly disconnect invalid service link connections helps maintain the overall connection stability and prevents instability caused by frequent connection interruptions or fluctuations. Finally, the terminal's ability to avoid transmitting data on unreliable links effectively saves bandwidth and other communication resources, ensuring the rational allocation and utilization of resources.

[0201] Referring to Figure 5, an embodiment of this disclosure provides a communication processing method. The executing entity may be a first communication device, which includes, but is not limited to, network-side devices that are not part of a terrestrial network, such as a satellite.

A 1-bit indication of "1" indicates that the service link between the terminal and the first communication device is available, and a 1-bit indication of "0" indicates that the service link between the terminal and the first communication device is unavailable.

[0204] For example, the tenth information is a 1-bit indication, and this 1-bit indication of "1" indicates that the second communication device is notified to terminate the downlink transmission.

[0205] It is understandable that the above "availability" includes whether it is available at the current time or after a period of time.

[0206] In some embodiments, time information includes remaining service time and / or service stop time.

[0207] In some embodiments, the second communication device is a network-side device (or a terrestrial network node) of the terrestrial network. For example, the terminal accesses the terrestrial network through the first communication device and the second communication device.

[0220] In some embodiments, the fourth information is used to indicate whether there is a communication link between the first communication device and other communication devices. For example, the fourth information is used to indicate whether there is an inter-satellite link (ISL), that is, the fourth information is used to indicate whether an ISL exists or not.

[0221] In some embodiments, the fourth information is used to indicate whether the communication link between the first communication device and other communication devices is available. For example, the fourth information is used to indicate that the inter-satellite link is available, or the fourth information is used to indicate that the inter-satellite link is unavailable.

[0222] In one embodiment of this disclosure, the method further includes:

[0235] In some embodiments, the first communication device determines whether the remaining effective duration of the feeder link is greater than or equal to the propagation delay between the first communication device and the second communication device (i.e., between satellite and ground). If not, the first communication device terminates UL data transmission and sends the tenth information to the terminal.

[0236] In other words, the first communication device determines whether the remaining effective duration of the feeder link is long enough to cover the propagation delay between the first and second communication devices (satellite and ground). If the determination finds that the remaining effective duration of the feeder link is insufficient to cover the propagation delay between the two devices, the first communication device will terminate uplink (UL) data transmission to ensure a valid communication link and reduce the possibility of communication interruption.

[0243] In this disclosure, the first communication device sends first information to the terminal to determine whether the service link is available. The terminal can determine whether the service link between the terminal and the first communication device is available based on the first information received from the first communication device. In this way, when the terminal determines that the service link is unavailable, it can notify the system to react quickly and take timely measures to reduce possible delays. Secondly, in the case of unavailable service links, the terminal can stop transmitting data or notify the first communication device to terminate downlink data transmission and / or notify the first communication device of the time information of the service link, avoiding accidental data loss or transmission errors during transmission. Thirdly, the terminal can promptly disconnect invalid service link connections, which helps maintain the stability of the overall connection and prevents the decrease in stability caused by frequent connection interruptions or fluctuations. Finally, the terminal can avoid transmitting data on unreliable links, which can effectively save bandwidth and other communication resources and ensure the rational allocation and utilization of resources.

[0244] In this disclosure, the first communication device sends tenth information to the second communication device. The tenth information is used to notify the second communication device to terminate downlink transmission and / or to notify the second communication device of the power supply link timing information. This enables the second communication device to respond quickly and terminate downlink transmission or adjust the power supply link timing information, thereby optimizing the communication link between the first and second communication devices, ensuring communication quality and stability, reducing latency and packet loss rate, and thus improving data transmission performance.

[0245] Referring to Figure 7, an embodiment of this disclosure provides a communication processing method applied to a second communication device, the specific steps of which include:
