The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0047] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this disclosure. The communication system may include, but is not limited to, a network-side device and an ATG terminal device. Figure 1 The number and form of the devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure. In actual applications, it may include two or more network-side devices and two or more ATG terminal devices. Figure 1 The communication system 10 shown is exemplified by including a network-side device 101 and an ATG terminal device 102.

[0048] It should be noted that the technical solutions of this disclosure can be applied to various communication systems. For example, Long Term Evolution (LTE) systems, 5th Generation (5G) mobile communication systems, 5G New Radio (NR) systems, or other future new mobile communication systems.

[0049] The network-side device 101 in this disclosure is an entity on the network side used for transmitting or receiving signals. For example, the network-side device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This disclosure does not limit the specific technology or device form used in the network-side device 101. The network-side device 101 provided in this disclosure can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure, the protocol layer of the network-side device 101 can be separated. For example, some protocol layer functions are centrally controlled by the CU, while the remaining part or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0050] The ATG terminal device 102 in this disclosure is a user-side entity used to receive or transmit signals, such as a mobile phone. An ATG terminal device can also be referred to as a user equipment (UE) terminal, mobile station (MS), mobile terminal (MT), etc. An ATG terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. This disclosure does not limit the specific technology or device form used in the ATG terminal device.

[0051] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0052] In addition, the following points are provided to facilitate understanding of the embodiments disclosed herein.

[0053] First, in the embodiments of this disclosure, "for indicating" can include both direct and indirect indication. When describing information as indicating A, it can include that the information carries A, or it can also include that the information directly or indirectly indicates A, without necessarily implying that the information carries A.

[0054] The information indicated by the information is called the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as, but not limited to, directly indicating the information to be indicated, such as the information to be indicated itself or its index. It can also be indirectly indicated by indicating other information, where there is a relationship between the other information and the information to be indicated. It can also indicate only a part of the information to be indicated, while the other parts are known or pre-agreed upon. For example, the indication of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing the indication overhead to some extent.

[0055] The information to be instructed can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This disclosure does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol.

[0056] Second, in the embodiments shown below, the terms "first," "second," and various numerical designations (e.g., #1, #2) are merely distinctions for ease of description and are not intended to limit the scope of the embodiments of this disclosure. For example, "first" and "second" in the embodiments of this disclosure can be used to distinguish types, not to distinguish object content.

[0057] Third, the “protocol” involved in the embodiments of this disclosure may refer to standard protocols in the field of communication, such as LTE protocol, NR protocol, WLAN protocol and related protocols in other communication systems, and this disclosure does not limit it.

[0058] Fourth, "at least one" means one or more, while "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can mean: a, or, b, or, c, or, a and b, or, a and c, or, b and c, or, a, b, and c. Here, a, b, and c can be single or multiple.

[0059] Fifth, this disclosure provides multiple implementation methods to clearly illustrate the technical solutions of this disclosure. Of course, those skilled in the art will understand that the multiple embodiments provided in this disclosure can be executed individually, or in combination with the methods of other embodiments in this disclosure, or individually or in combination with some methods in other related technologies; this disclosure does not limit these aspects.

[0060] Air-to-Ground (ATG) terminal equipment is a special type of terminal equipment, such as that used by aircraft and passengers. The connection between the aircraft and network-side equipment uses a 5G air interface, while the connection between the aircraft and passenger terminal equipment uses a Wi-Fi interface. The link between the ATG terminal equipment and the network-side equipment is considered a service link.

[0061] like Figure 2 As shown, in an air-to-ground scenario, network-side devices (such as the core network) provide an ATG (access node), such as the ATG air interface, to communicate with the aircraft.

[0062] Because the network-side equipment covers a large area, the propagation delay between the ATG terminal equipment and the network-side equipment cannot be ignored. Furthermore, due to the high speed of the aircraft, the Doppler frequency shift is significant, necessitating frequency compensation.

[0063] This disclosure provides an information acquisition method in which an ATG terminal device receives indication information sent by a network-side device. The indication information includes at least one of the following: first location information of the serving cell, second location information of neighboring cells, and scheduling offset information. This enables the ATG terminal device to acquire at least one of the following: first location information of the serving cell, second location information of neighboring cells, and scheduling offset information, in order to autonomously perform time-frequency compensation and improve communication quality.

[0064] The information acquisition method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0065] Please see Figure 3 , Figure 3 This is a flowchart of an information acquisition method provided in an embodiment of this disclosure. For example... Figure 3 As shown, this method is executed by the ATG terminal device, and the method may include, but is not limited to, the following steps:

[0066] S31: Receive indication information sent by the network-side device, wherein the indication information includes at least one of the following: the first location information of the serving cell, the second location information of the neighboring cells, and the scheduling offset information.

[0067] In this embodiment of the disclosure, the ATG terminal device is able to receive instruction information sent by the network-side device.

[0068] The indication information can be used to indicate the first location information of the serving cell, which provides network services to ATG terminal devices and can be the cell that the ATG terminal devices can access.

[0069] In some embodiments, the serving cell may be an ATG cell or a non-terrestrial network (NTN) cell.

[0070] The indication information can be used to indicate the second location information of neighboring cells. The neighboring cells can be cells belonging to the same base station as the serving cell, or cells belonging to different base stations than the serving cell.

[0071] The indication information can be used to indicate the scheduling offset information, which can be Koffset.

[0072] In some embodiments, the ATG terminal device receives indication information sent by the network-side device, and may receive indication information sent by the network-side device via broadcast.

[0073] In some embodiments, the ATG terminal device receives indication information sent by the network-side device, including at least one of the following:

[0074] Receive system information block SIB1 sent by the network-side device, wherein SIB1 includes indication information;

[0075] Receive SIB2 sent by the network-side device, wherein SIB2 includes indication information;

[0076] Receive a new SIB sent by the network-side device, wherein the new SIB includes indication information.

[0077] Understandably, ATG terminal devices can receive SIB19 messages sent by network-side devices to obtain at least one of the following: the first location information of the serving cell, the second location information of neighboring cells, and the scheduling offset information. However, on the one hand, SIB19 is based on a validity duration update mechanism, which is not suitable for ATG cells because their location is fixed. On the other hand, ATG terminal devices do not need to obtain precise location information of ATG cells. The location information bits in SIB19 are large, and the velocity information part is unnecessary, so it is necessary to consider how to reduce the bit overhead of location information. Furthermore, the propagation delay of ATG cells is usually less than 1 millisecond, and the Koffset value of 1 to 1024 milliseconds is not applicable to ATG cells, so it is necessary to consider introducing a finer-grained indication.

[0078] In this embodiment of the disclosure, the ATG terminal device can receive a system information block (SIB) 1 sent by the network-side device, wherein the SIB1 includes indication information. This reduces the bit overhead of location information indication and enables finer-grained indication of scheduling offset information.

[0079] In this embodiment of the disclosure, the ATG terminal device can receive SIB2 sent by the network-side device, wherein SIB2 includes indication information. This reduces the bit overhead of location information indication and enables finer-grained indication of scheduling offset information.

[0080] In this embodiment of the disclosure, the ATG terminal device can receive a new SIB sent by the network-side device, wherein the new SIB includes indication information. This reduces the bit overhead of location information indication and enables finer-grained indication of scheduling offset information.

[0081] For example, the new SIB could be SIB22, or SIB23, or SIB24, or SIB25, etc.

[0082] In some embodiments, if the ATG terminal device receives SIB1 or SIB2 or a new SIB sent by the network-side device, and SIB1 or SIB2 or the new SIB includes the second location information of the neighboring cell, the ATG terminal device can also receive the carrier frequency and cell identifier of the neighboring cell at the same time.

[0083] In some embodiments, when the neighboring cell is an intra-freq neighboring cell, the ATG terminal device can receive SIB3 sent by the network-side device, and the intra-frequency neighboring cell information (IntraFreqNeighCellInfo) of SIB3 includes the second location information of the neighboring cell. Alternatively, when the neighboring cell is an inter-freq neighboring cell, the ATG terminal device can receive SIB4 sent by the network-side device, and the inter-frequency neighboring cell information (InterFreqNeighCellInfo) of SIB4 includes the second location information of the neighboring cell.

[0084] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.

[0085] In some embodiments, the first location information and / or the second location information are indicated using ellipsoidal points.

[0086] In this embodiment of the disclosure, the first location information can be indicated using an ellipsoidal point.

[0087] In this embodiment of the disclosure, the second location information can be indicated using an ellipsoidal point.

[0088] In some embodiments, the ellipsoid point is configured such that the least significant bit of at least one of latitude and longitude is set to 0; or the ellipsoid point is configured to indicate only the first X most significant bits of latitude and the first Y most significant bits of precision, where X and Y are positive integers.

[0089] In this embodiment of the disclosure, the ellipsoid point is configured such that the least significant bit of at least one of the latitude and longitude is set to 0.

[0090] For example, the least significant bit of latitude and longitude is set to 0 to meet accuracy requirements, corresponding to a granularity of approximately X km / m. X is a system-defined value.

[0091] In this embodiment of the disclosure, the ellipsoid points are indicated by only the first X most significant bits of the latitude and the first Y most significant bits of the precision, where X and Y are positive integers.

[0092] For example, only the first X most significant bits of the latitude and the first Y most significant bits of the precision are indicated, where X and Y are system-defined values, such as X being 15 and Y being 16.

[0093] In some embodiments, scheduling offset information is indicated in at least one of the following ways:

[0094] Based on the flag identifier;

[0095] Based on enumeration values;

[0096] Integer-based approach;

[0097] Cell-specific scheduling offset cell (cellSpecificKoffset IE).

[0098] In this embodiment of the disclosure, the scheduling offset information can be indicated using a flag-based method.

[0099] In an exemplary embodiment, if the indication information includes the flag, the scheduling time offset is conventionally set to X milliseconds / slot / number of orthogonal frequency division multiplexing (OFDM) operations, where X can be a decimal or an integer. A decimal X is, for example, 0.1 to 1 (0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8), and an integer X is, for example, 1, 2, 3, 4, 5, 6, ..., 14. If the flag is not included, the scheduling time offset is 0.

[0100] For example, when using the slot method, the subcarrier space (SCS) is set to 15 kHz / 30 kHz.

[0101] In this embodiment of the disclosure, the scheduling offset information can be indicated using an enumeration-based method.

[0102] In the exemplary embodiment, scheduling offset information is indicated using an enumerated value-based approach. Enumerated values ​​include, for example, 0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8, 1, 2, 3, 4, 5, 6, ..., 14. The unit is milliseconds / slot / OFDM number. The number of bits used is less than or equal to 5 bits, for example, 1 to 5 bits are used.

[0103] For example, when using the slot method, the SCS is defined as 15KHz / 30KHz.

[0104] In this embodiment of the disclosure, the scheduling offset information can be indicated in an integer-based manner.

[0105] In the exemplary embodiment, scheduling offset information is indicated using an integer-based method, such as 0 to 100, 0 to 14, 0 to 15, in units of OFDM numbers, or integer multiples of 0.1ms / 0.25ms / 0.5ms.

[0106] In this embodiment of the disclosure, the scheduling offset information can be indicated using cellSpecificKoffset IE.

[0107] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.

[0108] In some embodiments, the scheduling offset information applies to at least one of the following states of the ATG terminal device:

[0109] Connected state;

[0110] Inactive state;

[0111] Idle state.

[0112] In this embodiment of the disclosure, the scheduling offset information applies to the ATG terminal device in the connected state.

[0113] For example, when the ATG terminal device is in a connected state, scheduling offset information can be used.

[0114] In this embodiment of the disclosure, the scheduling offset information applies to the ATG terminal device in an inactive state.

[0115] For example, when the ATG terminal device is in an inactive state, scheduling offset information can be used.

[0116] In this embodiment of the disclosure, the scheduling offset information applies to the ATG terminal device in the idle state.

[0117] For example, when the ATG terminal device is in an idle state, scheduling offset information can be used.

[0118] In some embodiments, if the serving cell is an ATG cell, the ATG terminal device specifies a duration for a specific time delay, wherein the specified duration is the round-trip time (RTT) between the ATG terminal device and the network-side device.

[0119] The specific time includes at least one of the following:

[0120] Startup time of the random access contention resolution timer ra-ContentionResolutionTimer;

[0121] The time of random access to the response window ra-ResponseWindow;

[0122] The start time of the non-continuous reception DRX activation time after sending the scheduling request SR.

[0123] In this embodiment of the disclosure, when the serving cell accessed by the ATG terminal device is an ATG cell, the ATG terminal device can delay the start time RTT of ra-ContentionResolutionTimer.

[0124] In this embodiment of the disclosure, when the serving cell accessed by the ATG terminal device is an ATG cell, the ATG terminal device can adjust the time delay (RTT) of the ra-ResponseWindow.

[0125] In this embodiment of the disclosure, when the serving cell accessed by the ATG terminal device is an ATG cell, the ATG terminal device can delay the start time (RTT) of the non-continuous reception DRX activation time after sending the scheduling request (SR).

[0126] In this embodiment of the disclosure, the network-side device can be an ATG network-side device, and the ATG network-side device may not be regarded as an NTN network-side device.

[0127] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0128] By implementing the embodiments of this disclosure, the ATG terminal device receives indication information sent by the network-side device, wherein the indication information includes at least one of the following: first location information of the serving cell, second location information of neighboring cells, and scheduling offset information. Therefore, the ATG terminal device can obtain at least one of the following: first location information of the serving cell, second location information of neighboring cells, and scheduling offset information, to autonomously perform time-frequency compensation and ensure communication reliability.

[0129] Please see Figure 4 , Figure 4 This is a flowchart of an information updating method provided in an embodiment of this disclosure. Figure 4 As shown, this method is executed by the ATG terminal device, and the method may include, but is not limited to, the following steps:

[0131] S42: Adjust the scheduling offset information according to MAC CE and determine the adjusted target scheduling offset information.

[0132] In this embodiment of the disclosure, the ATG terminal device can receive a media access control element (MAC CE) sent by the network-side device. The MAC CE is used to instruct adjustments to the scheduling offset information.

[0133] In some embodiments, the method for the ATG terminal device to obtain scheduling offset information may be to receive indication information sent by the network-side device.

[0173] Please see Figure 8 , Figure 8 This is a flowchart of an information configuration method provided in an embodiment of this disclosure. For example... Figure 8 As shown, this method is executed by the ATG terminal device, and the method may include, but is not limited to, the following steps:

[0174] S81: The connected ATG terminal device receives configuration information sent by the network-side device. The configuration information is used to instruct the ATG terminal device to use the scheduling offset information.

[0175] S82: Use scheduling offset information based on configuration information.

[0176] In this embodiment of the present disclosure, the connected ATG terminal device can receive configuration information sent by the network-side device. The configuration information is used to instruct the ATG terminal device to use scheduling offset information. Based on this, the ATG terminal device can use scheduling offset information according to the configuration information.

[0177] In an exemplary embodiment, when the ATG terminal device uses scheduling offset information based on configuration information, the scheduling time offset indicated by the scheduling offset information is defined as X milliseconds / slot / OFDM number, where X is a decimal or integer. Decimals can be 0.1 to 1 (0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8), and integers can be 1, 2, 3, 4, 5, 6, ..., 14, etc. If the configuration information does not instruct the ATG terminal device to use scheduling offset information, the scheduling time offset indicated by the scheduling offset information is 0.

[0178] In some embodiments, the method for the ATG terminal device to obtain scheduling offset information may be to receive indication information sent by the network-side device. The indication information is used to indicate the scheduling offset information, and the process can be referred to the relevant description in the above embodiments, which will not be repeated here.

[0179] The relevant descriptions of the scheduling offset information can be found in the descriptions in the above embodiments, and will not be repeated here.

[0180] In some embodiments, the connected ATG terminal device receives configuration information sent by the network-side device and can receive an RRC reconfiguration message sent by the network-side device, wherein the RRC reconfiguration message includes configuration information.

[0181] In some embodiments, the connected ATG terminal device receives configuration information sent by the network-side device and can receive a MAC CE sent by the network-side device, wherein the MAC CE includes configuration information.

[0182] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0183] It should be noted that in the embodiments of this disclosure, S81 to S82 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S31 and / or S41 to S42 and / or S51 to S52 and / or S61 to S62 and / or S71 to S72 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0184] By implementing the embodiments of this disclosure, the connected ATG terminal device receives configuration information sent by the network-side device. The configuration information instructs the ATG terminal device to use scheduling offset information; and the scheduling offset information is used according to the configuration information. Thus, the ATG terminal device can dynamically use scheduling offset information based on the configuration information of the network-side device to ensure communication quality.

[0185] Please see Figure 9, Figure 9 This is a flowchart of another information acquisition method provided in this embodiment of the disclosure. For example... Figure 9 As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps:

[0186] S91: Send indication information to the ATG terminal device, wherein the indication information includes at least one of the following: the first location information of the serving cell, the second location information of the neighboring cell, and the scheduling offset information.

[0187] In this embodiment of the disclosure, the network-side device can send instruction information to the ATG terminal device.

[0188] The indication information can be used to indicate the first location information of the serving cell, which provides network services to ATG terminal devices and can be the cell that the ATG terminal devices can access.

[0189] In some embodiments, the serving cell may be an ATG cell or an NTN cell.

[0190] The indication information can be used to indicate the second location information of neighboring cells. The neighboring cells can be cells belonging to the same base station as the serving cell, or cells belonging to different base stations than the serving cell.

[0191] The indication information can be used to indicate the scheduling offset information, which can be Koffset.

[0192] In some embodiments, the network-side device may send instruction information to the ATG terminal device via broadcast.

[0193] In some embodiments, the network-side device sends indication information to the ATG terminal device, including at least one of the following:

[0194] Send SIB1 to the ATG terminal device, wherein SIB1 includes indication information;

[0195] Send SIB2 to the ATG terminal device, wherein SIB2 includes indication information;

[0196] Send a new SIB to the ATG terminal device, wherein the new SIB includes indication information.

[0197] Understandably, network-side devices can send SIB19 to ATG terminal devices, indicating at least one of the following: the first location information of the serving cell, the second location information of neighboring cells, and scheduling offset information. However, on the one hand, SIB19 is based on a validity duration update mechanism, which is not suitable for ATG cells because their locations are fixed. On the other hand, ATG terminal devices do not need to obtain precise location information of ATG cells. The location information bits in SIB19 are large, and the velocity information part is unnecessary, so it is necessary to consider how to reduce the bit overhead of location information. Furthermore, the propagation delay of ATG cells is usually less than 1 millisecond, and the Koffset value of 1 to 1024 milliseconds is not applicable to ATG cells, so it is necessary to consider introducing a finer-grained indication.

[0198] In this embodiment of the disclosure, the network-side device can send SIB1 to the ATG terminal device, wherein SIB1 includes indication information. This reduces the bit overhead of location information indication and enables finer-grained indication of scheduling offset information.

[0199] In this embodiment of the disclosure, the network-side device can send SIB2 to the ATG terminal device, wherein SIB2 includes indication information. This reduces the bit overhead of location information indication and enables finer-grained indication of scheduling offset information.

[0200] In this embodiment of the disclosure, the network-side device can send a new SIB to the ATG terminal device, wherein the new SIB includes indication information. This reduces the bit overhead of location information indication and enables finer-grained indication of scheduling offset information.

[0201] For example, the new SIB could be SIB22, or SIB23, or SIB24, or SIB25, etc.

[0202] In some embodiments, if the network-side device sends SIB1 or SIB2 or a new SIB to the ATG terminal device, wherein SIB1 or SIB2 or the new SIB includes the second location information of the neighboring cell, the network-side device may also send the carrier frequency and cell identifier of the neighboring cell to the ATG terminal device at the same time.

[0203] In some embodiments, when the neighboring cell is an intra-freq neighboring cell, the network-side device may also send SIB3 to the ATG terminal device, wherein the intra-frequency neighboring cell information (IntraFreqNeighCellInfo) of SIB3 includes the second location information of the neighboring cell. Alternatively, when the neighboring cell is an inter-freq neighboring cell, the network-side device may also send SIB4 to the ATG terminal device, wherein the inter-frequency neighboring cell information (InterFreqNeighCellInfo) of SIB4 includes the second location information of the neighboring cell.

[0204] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.

[0205] In some embodiments, the first location information and / or the second location information are indicated using ellipsoidal points.

[0206] In this embodiment of the disclosure, the first location information can be indicated using an ellipsoidal point.

[0207] In this embodiment of the disclosure, the second location information can be indicated using an ellipsoidal point.

[0208] In some embodiments, the ellipsoid point is configured such that the least significant bit of at least one of latitude and longitude is set to 0; or the ellipsoid point is configured to indicate only the first X most significant bits of latitude and the first Y most significant bits of precision, where X and Y are positive integers.

[0209] In this embodiment of the disclosure, the ellipsoid point is configured such that the least significant bit of at least one of the latitude and longitude is set to 0.

[0210] For example, the least significant bit of latitude and longitude is set to 0 to meet accuracy requirements, corresponding to a granularity of approximately X km / m. X is a system-defined value.

[0211] In this embodiment of the disclosure, the ellipsoid points are indicated by only the first X most significant bits of the latitude and the first Y most significant bits of the precision, where X and Y are positive integers.

[0212] For example, only the first X most significant bits of the latitude and the first Y most significant bits of the precision are indicated, where X and Y are system-defined values, such as X being 15 and Y being 16.

[0213] In some embodiments, scheduling offset information is indicated in at least one of the following ways:

[0214] Based on the flag identifier;

[0215] Based on enumeration values;

[0216] Integer-based approach;

[0217] Cell-specific scheduling offset cell (cellSpecificKoffset IE).

[0218] In this embodiment of the disclosure, the scheduling offset information can be indicated using a flag-based method.

[0219] In an exemplary embodiment, if the indication information includes the flag, the scheduling time offset is conventionally set to X milliseconds / slot / number of orthogonal frequency division multiplexing (OFDM) operations, where X can be a decimal or an integer. A decimal X is, for example, 0.1 to 1 (0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8), and an integer X is, for example, 1, 2, 3, 4, 5, 6, ..., 14. If the flag is not included, the scheduling time offset is 0.

[0220] For example, when using the slot method, the subcarrier space (SCS) is set to 15 kHz / 30 kHz.

[0221] In this embodiment of the disclosure, the scheduling offset information can be indicated using an enumeration-based method.

[0222] In the exemplary embodiment, scheduling offset information is indicated using an enumerated value-based approach. Enumerated values ​​include, for example, 0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8, 1, 2, 3, 4, 5, 6, ..., 14. The unit is milliseconds / slot / OFDM number. The number of bits used is less than or equal to 5 bits, for example, 1 to 5 bits are used.

[0223] For example, when using the slot method, the SCS is defined as 15KHz / 30KHz.

[0224] In this embodiment of the disclosure, the scheduling offset information can be indicated in an integer-based manner.

[0225] In the exemplary embodiment, scheduling offset information is indicated using an integer-based method, such as 0 to 100, 0 to 14, 0 to 15, in units of OFDM numbers, or integer multiples of 0.1ms / 0.25ms / 0.5ms.

[0226] In this embodiment of the disclosure, the scheduling offset information can be indicated using cellSpecificKoffset IE.

[0227] It should be noted that the above embodiments are not exhaustive, but only illustrative of some embodiments. Furthermore, the above embodiments can be implemented individually or in combination. The above embodiments are only illustrative and are not intended to limit the scope of protection of the embodiments disclosed herein.

[0228] In some embodiments, the network-side device sends a MAC CE to the ATG terminal device, which is used to indicate that the scheduling offset information should be adjusted.

[0229] In this embodiment of the disclosure, the network-side device can send a MAC CE to the ATG terminal device. The MAC CE is used to indicate that the scheduling offset information should be adjusted.

[0230] In this embodiment of the disclosure, the network-side device can be an ATG network-side device, and the ATG network-side device may not be regarded as an NTN network-side device.

[0231] In some embodiments, the MAC CE can reuse the MAC CE (used to indicate target scheduling offset information) in related technologies, or a new MAC CE can be defined. If it is a newly defined MAC CE, its unit is the number of OFDMs or the number of slots, but based on SCS = 30 or 60 or 120, or 240KHz, or the unit is 0.1 / 0.2 / 0.25 / 0.5 milliseconds.

[0232] In some embodiments, if the network-side device does not send indication information to the ATG terminal device through SIB19, it updates the indication information using a system message update notification mechanism.

[0233] In this embodiment of the disclosure, the network-side device sends indication information to the ATG terminal device. If the indication information is not sent to the ATG terminal device through SIB19, for example, through at least one of SIB1, SIB2, or a new SIB, the indication information can be updated using a system message update notification mechanism.

[0234] For example, the instruction information can be updated through a paging mechanism.

[0235] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

This enables the ATG terminal device to obtain at least one of the following: first location information of the serving cell, second location information of neighboring cells, and scheduling offset information, in order to autonomously perform time-frequency compensation and ensure communication reliability.

[0247] It should be noted that in the embodiments of this disclosure, S101 to S102 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S91 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0248] By implementing the embodiments of this disclosure, the network-side device sends indication information to the ATG terminal device.

The network-side device also receives TAs reported by the ATG terminal device during the connection establishment random access phase, or during the connection restoration random access phase, or during the connection reconstruction random access phase. This enables the ATG terminal device to dynamically report TAs, thereby ensuring communication quality.

[0249] Please see Figure 11 , Figure 11 This is a flowchart of another TA reporting method provided in this disclosure embodiment. For example... Figure 11 As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps:

[0250] S111: Send a handover command to the ATG terminal device. The handover command is used to instruct the ATG terminal device to hand over to the target cell.

[0253] The handover command includes a TA reporting instruction, which instructs the ATG terminal device to report a TA to the network-side device.

[0254] Based on this, ATG terminal devices can access the target cell according to handover commands. The network-side equipment can receive the TA (Transmission Address) reported by the ATG terminal device during the handover process.

[0255] In this embodiment of the disclosure, the network-side device can be an ATG network-side device, and the ATG network-side device may not be regarded as an NTN network-side device.

[0256] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

The embodiments of this disclosure do not limit this.

[0258] By implementing the embodiments of this disclosure, the network-side device sends a handover command to the ATG terminal device. The handover command instructs the ATG terminal device to hand over to the target cell. The handover command includes a TA reporting instruction, which instructs the ATG terminal device to report its TA to the network-side device. The network-side device also receives the TA reported by the ATG terminal device during the process of accessing the target cell according to the handover command. This enables the ATG terminal device to dynamically report its TA, thereby ensuring communication quality.

[0259] Please see Figure 12 , Figure 12 This is a flowchart of another TA reporting method provided in this disclosure embodiment. For example... Figure 12 As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps:

[0263] In some embodiments, if the change in the current first TA relative to the previously reported second TA is greater than a trigger threshold, the ATG terminal device may report a first TA to the network-side device.

[0264] In some embodiments, if an ATG terminal device receives a connection reconfiguration message from a network-side device when there is no previously reported second TA, and the connection reconfiguration message includes a trigger threshold for TA reporting, the device can directly report the current first TA to the network-side device. Thus, the network-side device can receive the current first TA reported by the ATG terminal device when there is no previously reported second TA.

[0265] In this embodiment of the disclosure, the network-side device can be an ATG network-side device, and the ATG network-side device may not be regarded as an NTN network-side device.

[0266] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0267] It should be noted that in the embodiments of this disclosure, S121 to S122 can be implemented individually or in combination with any other step in the embodiments of this disclosure, such as in combination with S91 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0268] By implementing the embodiments of this disclosure, the network-side device sends a connection reconfiguration message to the ATG terminal device, wherein the connection reconfiguration message includes a trigger threshold for TA reporting; receives the first TA reported by the ATG terminal device when the change in the current first TA relative to the previously reported second TA is greater than the trigger threshold; or receives the current first TA reported by the ATG terminal device when the previously reported second TA does not exist. Therefore, the ATG terminal device can dynamically report TAs to ensure communication quality.

[0269] Please see Figure 13 , Figure 13 This is a flowchart of another information configuration method provided in an embodiment of this disclosure. For example... Figure 13 As shown, this method is executed by a network-side device, and the method may include, but is not limited to, the following steps:

[0270] S131: Send configuration information to the ATG terminal device in the connected state. The configuration information is used to instruct the ATG terminal device to use the scheduling offset information.

[0271] In this embodiment of the disclosure, the network-side device can send configuration information to the connected ATG terminal device. The configuration information is used to instruct the ATG terminal device to use the scheduling offset information. Based on this, the ATG terminal device can use the scheduling offset information according to the configuration information.

[0272] In an exemplary embodiment, when the ATG terminal device uses scheduling offset information based on configuration information, the scheduling time offset indicated by the scheduling offset information is defined as X milliseconds / slot / OFDM number, where X is a decimal or integer. Decimals can be 0.1 to 1 (0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8), and integers can be 1, 2, 3, 4, 5, 6, ..., 14, etc. If the configuration information does not instruct the ATG terminal device to use scheduling offset information, the scheduling time offset indicated by the scheduling offset information is 0.

[0273] In some embodiments, the method for the ATG terminal device to obtain scheduling offset information may be to receive indication information sent by the network-side device. The indication information is used to indicate the scheduling offset information, and the process can be referred to the relevant description in the above embodiments, which will not be repeated here.

[0274] The relevant descriptions of the scheduling offset information can be found in the descriptions in the above embodiments, and will not be repeated here.

[0275] In some embodiments, the network-side device sends configuration information to the connected ATG terminal device, and may send an RRC reconfiguration message to the connected ATG terminal device, wherein the RRC reconfiguration message includes configuration information.

[0276] In some embodiments, when a connected ATG terminal device receives configuration information sent by a network-side device, it can send a MAC CE to the connected ATG terminal device, wherein the MAC CE includes configuration information.

[0277] In this implementation or embodiment, unless there is a contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or examples can be arbitrarily combined, and can be arbitrarily combined with other implementations or embodiments.

[0278] It should be noted that in the embodiments of this disclosure, S131 can be implemented alone or in combination with any other step in the embodiments of this disclosure, such as in combination with S91 and / or S101 to S102 and / or S111 to S112 and / or S121 to S122 in the embodiments of this disclosure. The embodiments of this disclosure do not limit this.

[0279] By implementing the embodiments of this disclosure, the network-side device sends configuration information to the ATG terminal device in a connected state. This configuration information instructs the ATG terminal device to use scheduling offset information. Therefore, the ATG terminal device can dynamically use the scheduling offset information based on the network-side device's configuration information to ensure communication quality.

[0280] To facilitate understanding of the embodiments of this disclosure, an exemplary embodiment is provided.

[0281] In the exemplary embodiment, due to the large coverage area of ​​the network-side equipment (e.g., ATG gNB), the propagation delay between the ATG terminal device and the ATG gNB cannot be ignored. Furthermore, due to the high speed of the aircraft and the large Doppler frequency shift, frequency compensation is also necessary. By broadcasting its location to the ATG gNB, the ATG terminal device can calculate the air interface propagation delay between them based on its own location and the ATG gNB's location, and compensate for the frequency offset based on its own speed, thereby achieving the effect of autonomous time-frequency compensation by the ATG terminal device.

[0282] The network-side equipment is considered to broadcast the location information (first location information of the serving cell and / or second location information of neighboring cells) and Koffset information (scheduling offset information) of ATG cells. However, the broadcasting method for the location and Koffset information is not clearly defined. If the location and Koffset information from SIB19 are reused, firstly, SIB19 is based on a validity duration update mechanism, which is not suitable for ATG cells because their location is fixed. Secondly, ATG cells do not need to broadcast precise location information, and the existing SIB19 has a large number of bits for location information, and the velocity information portion is not needed. Therefore, it is necessary to consider how to reduce the bit overhead of the location information. Furthermore, the propagation delay of ATG cells is usually less than 1 millisecond, and the existing Koffset values ​​of 1 to 1024 milliseconds are not applicable to ATG cells. It is necessary to consider introducing a finer-grained indication.

[0283] In addition, if the ATG cell does not belong to the NTN cell, it is necessary to further consider the impact of the terminal device -gNB RTT on the MAC timer, the connection state Koffset update mechanism, and the ATG terminal device TA reporting mechanism for the ATG cell.

[0284] In some embodiments, the ATG terminal device receives serving cell (base station) location information (first location information of the serving cell, hereinafter the same) broadcast by the cell, or scheduling offset information, or location information of neighboring cells (first location information of the neighboring cells, hereinafter the same).

[0285] Optionally, the cell can broadcast its location information and scheduling offset information via system messages SIB1, SIB2, or a new SIB such as SIB22, SIB23, SIB24, SIB25, etc. (currently, NR system messages are defined up to SIB21). The scheduling offset information is also known as Koffset.

[0286] Optionally, the indication information applies to ATG terminal devices accessing ATG cells.

[0287] Optionally, the cell broadcast instruction information may further include TA reporting instructions to enable TA (timing advanced) reporting during the random access phase of connection establishment / connection recovery / connection reconstruction.

[0288] Optionally, the location information of neighboring cells is carried in the IntraFreqNeighCellInfo of SIB3 for intra-freq cells, and in the InterFreqNeighCellInfo of SIB4 for inter-freq cells.

[0289] Optionally, the location information of neighboring cells can be carried in a new SIB or in SIB1 / 2. If carried in SIB1 / 2 or a new SIB, the carrier frequency and cell identifier of the cell must also be indicated.

[0290] In some embodiments, location information (first location information of the serving cell and / or second location information of neighboring cells) is indicated using an Ellipsoid-Point approach.

[0291] In some embodiments, when using the Ellipsoid-Point method, the definition in TS 37.355 can be adopted: The least significant bits of degreesLatitude and degreesLongitude are set to 0 to meet the accuracy requirement corresponds to a granularity of approximately X km / meter. X is a system-defined value.

[0292] In some embodiments, the Ellipsoid-Point approach can be similar to the definition in TS 37.355, but only indicates the first X MSBs of degreesLatitude and the first Y MSBs of degreesLongitude. X and Y are system-defined values, such as X=15 and Y=16.

[0293] In some embodiments, the scheduling offset information indication includes one or more of the following methods:

[0294] The flag-based approach: If the system message contains the flag, the scheduling time offset is defined as X milliseconds / slot / OFDM number, where X is a decimal or integer. Decimals are ranges from 0.1 to 1 (0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8), and integers are 1, 2, 3, 4, 5, 6, ..., 14. If the flag is not included, the scheduling time offset is 0. For the slot-based approach, the SCS is defined as 15kHz / 30kHz.

[0295] Based on enumerated values: Enumerated values ​​include, for example, 0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8, 1, 2, 3, 4, 5, 6, ..., 14. The unit is milliseconds / slot / OFDM number. The number of bits used is less than or equal to 5 bits, for example, using 1 to 5 bits. For the slot-based method, the SCS is conventionally set to 15kHz / 30kHz.

[0296] Integer-based methods: for example, 0~100, 0~14, 0~15, in units of OFDM numbers, or integer multiples of 0.1ms / 0.25ms / 0.5ms;

[0297] Use the existing cellSpecificKoffset IE.

[0298] In some embodiments, the scheduling offset information applies to one or more of the following states: idle state, inactive state, and connected state.

[0299] In some embodiments, the ATG terminal device receives a Differential Koffset MAC CE sent by the base station, and the MAC CE can be used by the ATG cell to adjust the Koffset of the ATG terminal device.

[0300] Optionally, this method applies to cases where ATG cells are not considered NTN cells.

[0301] Optionally, the ATG terminal device dynamically adjusts the Koffset received from system messages based on the Differential Koffset MAC CE.

[0302] Optionally, the Differential Koffset MAC CE may reuse an existing Differential Koffset MAC CE or define a new MAC CE. If it is a newly defined MAC CE, its unit is the number of OFDMs or the number of slots, but based on SCS = 30, 60, 120, or 240 kHz. Or the unit is 0.1 / 0.2 / 0.25 / 0.5 milliseconds.

[0303] In some embodiments, if the ATG terminal device receives a TA report instruction broadcast by the cell, the ATG terminal device reports a TA during the random access phase of connection establishment, connection recovery, or connection reconstruction.

[0304] Optionally, this method applies to cases where ATG cells are not considered NTN cells.

[0305] In some embodiments, if the ATG terminal device receives a TA report instruction in the handover command, the ATG terminal device reports a TA when accessing the target cell.

[0306] Optionally, this method applies to cases where ATG cells are not considered NTN cells.

[0307] In some embodiments, the base station configures the trigger threshold for TA report of ATG terminal device through connection reconfiguration message. If the change in the current TA of ATG terminal device relative to the last reported TA is greater than the threshold, ATG terminal device triggers TA reporting.

[0308] Optionally, this method applies to cases where ATG cells are not considered NTN cells.

[0309] In some embodiments, if the connected ATG terminal device has not reported TA and the network is configured with a TA report threshold, the ATG terminal device triggers the reporting of TA.

[0310] Optionally, this method applies to cases where ATG cells are not considered NTN cells.

[0311] In some embodiments, the connected ATG terminal device receives a scheduling offset enable indication (configuration information) sent by the base station, and the ATG terminal device uses the scheduling offset after receiving the message (configuration information).

[0312] Optionally, if scheduling offset is enabled, the scheduling time offset is defined as X milliseconds / slot / OFDM number, where X is a decimal or integer. Decimals are such as 0.1 to 1 (0.1, 0.2, 0.25, 0.4, 0.5, 0.75, 0.8), and integers are such as 1, 2, 3, 4, 5, 6, ..., 14, etc. If scheduling offset is disabled, the scheduling time offset is 0.

[0313] Optionally, the scheduling offset enable indication (configuration information) can be expressed as an RRC reconfiguration message or a MAC CE.

[0314] In some embodiments, if the information broadcast by the base station is not broadcast via SIB19, its updates are made through the system message update notification mechanism, i.e., paging.

[0315] In some embodiments, if an ATG terminal device accesses an ATG cell, the startup time delay for one or more of the following terminal devices—gNB RTT—is as follows:

[0316] ra-ContentionResolutionTimer

[0317] ra-ResponseWindow

[0318] DRX active time start time after ATG terminal device sends SR

[0319] Optionally, this method applies to cases where ATG cells are not considered NTN cells.
