Depending on the context, words used herein may be interpreted as meaning "when," "when," or "in response to a determination."

[0035] Please refer to Figure 1A This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1A As shown, the wireless communication system is a communication system based on cellular mobile communication technology. This wireless communication system may include: a plurality of UEs 11 and a plurality of access devices 12. In some embodiments, the communication system may further include: one or more core network devices, in... Figure 1A Core network equipment is not shown. This core network equipment includes, but is not limited to, Mobile Management Entity (MME) or Access Management Function (AMF).

[0036] UE 11 can be a device that provides voice and / or data connectivity to a user. UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). UE 11 can be an IoT UE, such as a sensor device, a mobile phone (or cellular phone), and a computer with an IoT UE. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE 11 can also be a device in an unmanned aerial vehicle (UAV). Alternatively, UE 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, UE 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0037] Access device 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be the next generation after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0038] The access device 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, the access device 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When the access device 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DUs). The central unit is equipped with a protocol stack of the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of the access device 12.

[0039] Access device 12 and UE 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0040] In the research of wireless communication technology, satellite communication is considered an important aspect of the future development of wireless communication technology. Satellite communication refers to communication using satellites as relays by terrestrial radio communication equipment, or communication using wireless communication equipment mounted on satellites. A satellite communication system consists of a satellite component and a ground component. The characteristics of satellite communication are: large communication range; communication can be conducted between any two points within the coverage area of ​​the satellite's emitted radio waves; and it is less affected by land-based disasters (high reliability). As a supplement to the current terrestrial cellular communication system, satellite communication can offer the following advantages:

[0041] Extended coverage: For areas that cannot be covered by current cellular communication systems or where the cost of coverage is too high, such as oceans, deserts, and remote mountainous areas, satellite communication can be used to solve the communication problem.

[0042] Emergency communications: In extreme situations such as disasters like earthquakes that render cellular communication infrastructure unavailable, satellite communications can be used to quickly establish communication connections.

[0043] Provides industry applications: For example, for latency-sensitive services that require long-distance transmission, satellite communication can be used to reduce the latency of service transmission.

[0044] It is foreseeable that in future wireless communication systems, satellite communication systems and terrestrial cellular communication systems will gradually achieve deep integration, truly realizing the Internet of Everything. In satellite communication systems, the long propagation distance leads to significant discrepancies in uplink and downlink timing. Terminals need to rely on Global Navigation Satellite System (GNSS) measurements and other auxiliary information to maintain uplink synchronization.

[0045] In satellite communication scenarios, the long signal transmission distance between the transmitter and receiver results in significant data transmission time. Uplink (UL) and downlink (DL) time slots with the same time slot number at a base station may or may not be aligned in the time domain. For example... Figure 1B As shown, the nth uplink and nth downlink time slots of the base station are aligned in the time domain. There is a timing advance (TA) between the nth UL time slot and the nth DL time slot of the UE. Figure 1C As shown, the nth DL time slot of the base station is earlier than the nth UL time slot. Obviously, the uplink and downlink time slots with the same sequence number of the base station are not aligned in the time domain. At this time, there is a TA between the UE's UL time slot and DL time slot.

[0046] Figure 1D As shown, the beams emitted by the NTN equipment on satellites 1, 2, and 3 can all cover the area where the terminal is located. To improve transmission bandwidth or enhance data transmission reliability, the terminal can perform carrier aggregation. The different carriers in the carrier aggregation can be different beams from the same satellite or service beams from different satellites.

[0047] like Figure 2A As shown, this disclosure provides an information processing method, which is executed by a UE, the method comprising:

[0048] S1110: Receive configuration information; wherein the configuration information indicates at least a first carrier; the first carrier includes: multiple carriers belonging to the NTN device;

[0049] S1120: Determine the second carrier based on the configuration information.

[0050] The second carrier can be used for carrier aggregation or dual connectivity of the UE.

[0051] The UE can be any type of communication device, such as... Figure 1A The UE shown can include: mobile phones, tablets, wearable devices, in-vehicle devices, smart home devices, smart office devices, or flight devices, etc.

[0052] For example, configuration information sent by an NTN device is received, which may be carried in an RRC message, a MAC layer message, or downlink control information (DCI).

[0053] The configuration information indicates at least that the UE can use multiple carriers for carrier aggregation or dual connectivity.

[0054] These multiple first carriers are carriers belonging to NTN devices, i.e., NTN carriers, which are carriers used by the NTN network.

[0055] For example, different first carriers may come from the same NTN device or from different NTN devices.

[0056] Carrier aggregation, when a UE supports carrier aggregation, allows two or more carriers belonging to the same Radio Access Technology (RAT) to be used simultaneously as the UE's serving carriers, thereby increasing transmission bandwidth and transmission rate.

[0057] Dual connectivity means that when a UE supports dual connectivity, it can establish connections with two or more cells simultaneously. These cells can support the same or different RATs, and each cell can communicate with the UE through one or more carriers.

[0058] It is worth noting that carrier aggregation and dual connectivity can be performed simultaneously or at different times.

[0059] The NTN device can be any air device of the NTN. For example, the air device may include an NTN access device or an NTN relay device. It is worth noting that the first carrier can be a carrier of one or more NTN devices.

[0060] The UE can select some or all of the multiple first carriers for carrier aggregation and / or dual connectivity.

[0061] Thus, UEs accessing the NTN can also increase transmission bandwidth and improve transmission rate based on carrier aggregation and / or dual connectivity.

[0062] In some embodiments, the configuration information includes:

[0063] First carrier information, indicating the first carrier;

[0064] First-time information indicates the availability time of the first carrier.

[0065] For example, the first carrier information may include at least one of the following:

[0066] Carrier identifier, wherein one carrier identifier indicates a first carrier;

[0067] Carrier group identifier, wherein a carrier group identifier indicates a carrier group, and a carrier group includes one or more carriers;

[0068] A carrier set identifier, wherein a carrier set identifier indicates a carrier set, a carrier set may include: one or more carrier groups, or one or more carriers.

[0069] As another example, the first carrier information may include: frequency information of the first carrier. Exemplarily, this frequency information may indicate the frequency point number of the carrier, the number of the band width part (BWP), the number of the subcarrier, etc. In some embodiments, the frequency information may include: the frequency value of the center frequency and the bandwidth value, etc.

[0070] In summary, the first carrier information can be any information that can determine the first carrier.

[0071] In some embodiments, the configuration information may include first carrier information separately, and the availability time of each first carrier may be confirmed according to the protocol; alternatively, the UE may consider the time period between receiving the configuration information and the preset signaling as the availability time of the first carrier. The preset signaling may indicate carriers whose first carriers can no longer be used.

[0072] The first time information can be any information that can determine the availability time of the first carrier. This first time information can be optional information in the configuration information.

[0073] For example, the first time information may include duration information. For instance, after receiving the configuration information, the UE may consider the time at which the configuration information is received as the start time of the first carrier's available time. Since the duration information indicates the available duration, the start time offset in the time domain by an amount equal to the available duration indicated by the duration information can determine the end time of the first carrier's available time.

[0074] As another example, the first time information may include: start time information. The start and end time information respectively indicates the start and end times of the available time of the first carrier.

[0075] Again, by way of example, the first time information may include: termination time information, indicating the end time of the available time. In this case, the start time of the available time may be determined according to predefined rules such as protocol agreements, or determined by a start instruction sent by the NTN device.

[0076] For example, the available time of the first carrier can be determined based on a preset area, such as the tracking area (TA) or cell group where the UE is currently located, covered by the first carrier. The UE may move within this preset area, and different UEs may be located at different points within the preset area; for example, some UEs may be located at the edge of the preset area, while others may be located in the middle. Therefore, the time range during which UEs at different locations can use the first carrier to communicate with the network side varies. Multiple cells within a cell group may be distributed adjacently on the ground surface.

[0077] In some instances, NTN can provide continuous or discontinuous coverage of the ground. If NTN provides discontinuous coverage, some areas on the ground may not have NTN network signal coverage during certain time periods. The aforementioned first time information can be the time range within which the network signal of the NTN device to which the first carrier belongs can cover a preset area.

[0078] In some embodiments, determining the second carrier based on the configuration information includes: selecting a second carrier that meets preset conditions from the first carrier based on the configuration information.

[0079] For example, the preset condition may be a carrier aggregation condition or a dual-connection condition. In this approach, the UE selects a second carrier from the first carrier that meets the preset condition.

[0080] For example, if the condition information of the preset conditions can limit the carrier attributes that can be used as the second carrier, then at least the first carrier that can be used as the second carrier can be selected based on the carrier attributes of the first carrier.

[0081] In some other embodiments, determining the second carrier based on the configuration information includes: removing the first carrier that does not meet the preset conditions based on the configuration information.

[0082] In this embodiment, the UE selects a second carrier that does not meet the conditions from the first carrier, and the remaining first carrier is the second carrier that meets the preset conditions.

[0083] For example, the condition information of the preset conditions limits the carrier attributes that cannot be used as the second carrier. In this case, the first carrier that cannot be used as the second carrier can be excluded based on the carrier attributes of the first carrier, and the remaining first carrier is the carrier that can be used for UE carrier aggregation and / or dual connectivity.

[0084] In some embodiments, the second carrier includes at least one of the following:

[0085] The orbital altitude of any NTN device to which the second carrier belongs is within a first range; the relative distance between the UE and the NTN device to which the second carrier belongs is within a second range;

[0086] The timing quantity corresponding to the second carrier is within the third range.

[0087] The second carrier here is the carrier mentioned above used for UE carrier aggregation or dual connectivity.

[0088] NTN devices at different orbital altitudes have different transmission delays (i.e., timings) relative to the same location on the ground. To enable UEs to better implement carrier aggregation, the orbital altitudes of multiple NTN devices belonging to secondary carriers should be similar. This way, the difference between uplink and downlink timings between the UE and the NTN devices is small, facilitating signaling and / or data transmission between the UE and the network side based on carrier aggregation or dual connectivity.

[0089] For example, the orbital height difference between the NTN devices to which the two second carriers belong can be between 8 km and 12 km. For example, the orbital height difference between the NTN devices to which the two second carriers belong can be less than or equal to 10 km.

[0090] If the distance difference between the UE and different NTN devices is small, the latency difference between the UE communicating with the NTN devices on the two carriers will be approximately the same. Therefore, the requirements for the UE's carrier aggregation and / or dual connectivity capabilities are relatively low. Thus, it is acceptable to require that the relative distance between the UE and the NTN devices on the second carrier both be within a second range. The difference between the upper and lower limits of the second range can be 8 km to 12 km, specifically 10 km.

[0091] The timing parameters here include, but are not limited to, Timing Advance (TA) and other delay parameters. For example, these other delay parameters include, but are not limited to, the Timing Offset (Koffset). This Timing Offset can be used to determine the transmission timing for the following channels:

[0092] The transmission timing of the Physical Uplink Shared Channel (PUSCH) scheduled by Downlink Control Information (DCI); this transmission timing includes, but is not limited to, Channel State Information (CSI) on the PUSCH and / or the timing of service data transmission on the PUSCH.

[0093] PUSCH transmission timing authorized and scheduled by Random Access Response (RAR);

[0094] Timing of Hybrid Automatic Repeat Request-Acknowledge character (HARQ) transmission on the Physical Uplink Control Channel (PUCCH);

[0095] CSI reference source timing;

[0096] Timing of non-periodic sounding reference signal (SRS) transmission.

[0097] Of course, the above are just examples to illustrate transmission delay, and the actual implementation is not limited to the examples above.

[0098] The distance between the UE and the NTN device (e.g., the NTN's air device) is an important variable that determines the transmission delay. In order to achieve carrier aggregation or dual connectivity for the UE, in this embodiment of the disclosure, we do not need to focus on the orbital altitude of the NTN device, but rather on the relative distance between the NTN device and the UE. If the difference between the relative distances between the NTN devices and the UE to which any two carriers belong is within a second range, then the two carriers can be used as the second carrier for UE carrier aggregation / or dual connectivity.

[0099] In other embodiments, the timing difference between the NTN device and the UE on any two carriers is very small, for example, the timing difference is within a third range. This indicates that the UE can simultaneously perform uplink and / or downlink transmissions based on these two carriers, meaning that these two carriers meet the requirements of carrier aggregation and / or dual connectivity. For example, the timing difference between the TAs of the NTN devices corresponding to any two second carriers used by the UE for carrier aggregation or dual connectivity is within 8µs to 12µs, such as 10µs.

[0100] The above are merely examples illustrating carriers that meet the second preset condition; specific implementations are not limited to the examples above.

[0101] For example, the aforementioned information processing method may include at least one of the following:

[0102] Based on the configuration information, the first carrier whose orbital height of the corresponding NTN device is within a first range is determined as the second carrier;

[0103] Based on the configuration information, the first carrier whose relative distance between the corresponding NTN device and the UE is within a second range is determined as the second carrier;

[0104] Based on the configuration information, the first carrier with the corresponding timing quantity located in the third range is determined as the second carrier.

[0105] For example, the timing quantity corresponding to the second carrier is within the third range, including:

[0106] The difference between the uplink timing parameters corresponding to any two second carriers is less than the first threshold;

[0107] And / or,

[0108] The difference between the downlink timing adjustment parameters corresponding to any two second carriers is less than the second threshold.

[0109] The uplink timing parameter can be either the TA or Koffset transmitted by the UE uplink. The downlink timing parameter can be either the TA or Koffset received by the UE downlink.

[0110] In some embodiments, the first threshold and the second threshold may be equal or unequal. For example, the first threshold and / or the second threshold may both be 5µs, 6µs, 7µs, or 10µs, etc.

[0111] The UE can select multiple second carriers with a difference of uplink timing less than a first threshold to perform uplink transmission based on carrier aggregation or dual connectivity, in order to increase transmission bandwidth and / or obtain frequency gain.

[0112] The UE can select multiple second carriers with a difference of downlink timing less than a second threshold to perform downlink transmission based on carrier aggregation or dual connectivity, in order to increase transmission bandwidth and / or obtain frequency gain.

[0113] For example, determining the first carrier whose corresponding timing quantity is located in the third range as the second carrier based on the configuration information includes:

[0114] Based on the configuration information, the first carrier whose corresponding uplink timing difference is less than the first threshold is determined as the second carrier;

[0115] And / or,

[0116] Based on the configuration information, the first carrier whose downlink timing difference is less than the second threshold is determined as the second carrier.

[0117] like Figure 2B As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE), the method comprising:

[0118] S1210: Receive configuration information; wherein the configuration information indicates at least a first carrier; the first carrier includes: multiple carriers of the NTN device;

[0119] S1220: Determine the second carrier based on the configuration information.

[0120] S1230: Based on the second carrier, transmit indication information, wherein the indication information is at least used to determine the second carrier.

[0121] In this embodiment of the disclosure, if the UE selects a second carrier, it will report the relevant information (i.e., indication information) of the selected second carrier to the NTN device.

[0122] This indication information can be carried by RRC messages, MAC messages, or Uplink Control Information (UCI) sent by the UE. The RRC message can be an RRC connection request message, an RRC recovery request message, or an RRC connection re-establishment request message, etc. The MAC message can be a MAC control element (CE).

[0123] By sending indication information, the NTN device can know that the UE has selected two or more second carriers for carrier aggregation and / or establishing dual connectivity, so that the NTN device can further perform related scheduling.

[0124] In some embodiments, the indication information is used at least to determine the second carrier.

[0125] The indication information may include second carrier information, which can be used by the NTN device to determine the second carrier.

[0126] For example, the second carrier information may include a carrier identifier, which can be used by the NTN device to determine the second carrier.

[0127] As another example, the second carrier information may include: a carrier set identifier and / or frequency information.

[0128] If the indication information indicates the second carrier, then the UE directly informs the NTN device of the second carrier it has selected.

[0129] In some other embodiments, the indication information indicates at least the first carrier other than the second carrier.

[0130] Since the configuration information comes from the NTN device, and this configuration information can be used to determine the first carrier, if the indication information indicates a first carrier other than the second carrier, then the remaining first carrier is the second carrier. That is, after receiving the indication information, the NTN device can determine the second carrier by combining the configuration information and the indication information.

[0131] In some embodiments, the indication information further includes:

[0132] The second time information indicates the time range during which the UE uses the second carrier.

[0133] The second time information may be: the UE determines the time period for the second carrier to be used for carrier aggregation and / or dual connectivity based on its own location, the operating trajectory information of the NTN device and / or the first time information, and uses the second time information to indicate the time period.

[0134] For example, the time period indicated by the second time information may be a sub-time period of the time period indicated by the first time information, and / or the time period indicated by the second time information may be partially within the time period indicated by the first time information and partially outside the time period indicated by the first time information.

[0135] like Figure 2C As shown, this disclosure provides an information processing method, which is executed by a user equipment (UE), the method comprising:

[0136] S1310: Receive timing adjustment information, wherein the timing adjustment information is used to adjust the timing amount corresponding to one or more second carriers.

[0137] The second carrier may be one or more serving carriers of the UE. Multiple second carriers may be carriers from different NTN devices, or different carriers from the same NTN device. For example, the second carrier may be a carrier for carrier aggregation and / or dual connectivity of the UE.

[0138] In one embodiment, the timing adjustment information may include the adjusted timing amount. Thus, after receiving the timing adjustment information, the UE can determine the adjusted timing amount by decoding the timing adjustment information.

[0139] In another embodiment, the timing adjustment information may indicate timing adjustment parameters such as adjustment amount or adjustment ratio for timing quantities corresponding to one or more second carriers. The adjustment amount (also called timing adjustment quantity) and adjustment ratio may be the timing adjustment parameters indicated by the timing adjustment information. The timing adjustment parameters can be directly used to adjust the timing quantity.

[0140] For example, after receiving the timing adjustment information, the UE needs to calculate the updated timing amount based on the timing adjustment parameter and the current timing amount. For instance, assuming the timing adjustment parameter is an adjustment amount, the UE, after receiving the adjustment value, needs to perform addition or subtraction operations between the adjustment amount and the current timing amount to calculate the updated timing amount. Alternatively, assuming the timing adjustment parameter is an adjustment ratio, the UE, after receiving the adjustment ratio, needs to perform multiplication operations between the adjustment ratio and the current timing amount to obtain the product, which is the updated timing amount.

[0141] This timing adjustment information can be used to adjust the uplink timing amount corresponding to one or more second carriers.

[0142] This timing adjustment information can also be used to adjust the downlink timing amount corresponding to one or more second carriers.

[0143] This timing adjustment information can be carried in any downlink message. This downlink message can be an RRC message, a MAC message, or a DCI message.

[0144] In this embodiment of the disclosure, the reporting of timing adjustment information can be used by the UE to adjust the uplink timing amount and / or the downlink timing amount, thereby making the timing amount most suitable for the UE relative to the location of the NTN device to which the second carrier belongs.

[0145] It is worth noting that this information processing method can be implemented alone or in combination with any of the aforementioned technical solutions. For example, this information processing method can be combined with the aforementioned... Figure 2A and / or Figure 2B The information processing methods shown are implemented in combination.

[0146] In some embodiments, receiving timing adjustment information includes:

[0147] Receive scheduling information containing the timing adjustment information and scheduling instructions;

[0148] The scheduling instruction is used to schedule the transmission of the UE.

[0149] The scheduling instruction can be a scheduling instruction for uplink transmission and / or a scheduling instruction for downlink transmission of the UE.

[0150] The scheduling instruction may be a scheduling instruction for PUSCH transmission and / or PUCCH transmission; or, the scheduling instruction may be a scheduling instruction for PDSCH transmission and / or PDCCH transmission.

[0151] By including timing adjustment information and scheduling instructions together in the scheduling information, the NTN device carries timing adjustment information when performing transmission scheduling. This allows the UE to execute the uplink and / or downlink transmissions scheduled by the scheduling instructions based on the timing adjustment information, thereby saving signaling overhead.

[0152] For example, the scheduling information can be carried in the DCI, so that the timing of the UE's use of each second carrier can be dynamically and in a timely manner through the DCI.

[0153] In some embodiments, the timing adjustment information includes one or more first information fields;

[0154] One of the first information fields is used to indicate a timing adjustment parameter; wherein the timing adjustment parameter is used to adjust the timing amount.

[0155] In this embodiment, the information indicated by one of the first information fields corresponds to a timing adjustment parameter, which can be used to adjust the timing amount corresponding to part or all of the second carrier.

[0156] The first information field may include one or more bits. A bit value in the first information field may indicate a timing adjustment parameter.

[0157] Thus, if the UE is configured with X second carriers, the timing adjustment information may include Y first information fields. Here, X can be any positive integer, and Y is a positive integer less than or equal to X.

[0158] In one embodiment, a first information field corresponds to a second carrier; that is, the timing adjustment parameters carried by the first information field are used to adjust the timing amount corresponding to the second carrier. In this way, the NTN device can flexibly adjust the timing amount of each second carrier according to the movement of each NTN device and / or changes in the wireless environment.

[0159] In another embodiment, one of the first information fields indicates one timing adjustment parameter, which can be used to adjust the timing amounts corresponding to multiple second carriers, for example, it can be used to adjust the timing amounts corresponding to all second carriers. This is applicable to situations where multiple second carrier systems are being adjusted. For example, if the NTN devices to which the multiple second carriers belong are of the same type of airborne equipment, then the timing adjustments corresponding to the multiple second carriers can be indicated by a single first information field. The type of airborne equipment is adapted to the satellite type; for example, if the satellites corresponding to the multiple second carriers are all geostationary satellites, low-Earth orbit satellites, and / or high-Earth orbit satellites, then the timing adjustments corresponding to the multiple second satellites can be indicated by a single first information field.

[0160] For example, the timing adjustment parameter may be: the adjustment ratio of the timing amount, and / or the timing adjustment amount.

[0161] Table 1 shows a schematic diagram of a timing adjustment amount indicated by a first information field.

[0162] 00 Timed adjustment amount A 01 Timed adjustment quantity B 10 Timed adjustment amount C 11 Timed adjustment amount D

[0163] Table 1

[0164] Any row in Table 1 can be used alone or in combination with other rows.

[0165] In some embodiments, the timing adjustment information includes a second information field;

[0166] Any indication value carried in the second information field corresponds to a timing adjustment parameter group; wherein, the timing adjustment parameter group includes one or more timing adjustment parameters; any timing adjustment parameter in the timing adjustment parameter group corresponds to one or more of the second carriers.

[0167] The timing adjustment parameter can be either a timing adjustment percentage or a timing adjustment amount.

[0168] For example, a timing adjustment parameter group may include a timing adjustment parameter. This timing adjustment parameter can be used to adjust the timing amount of all second carriers.

[0169] As an example, a timing adjustment parameter group may include multiple timing adjustment parameters. A timing adjustment parameter can be used to determine the timing amount of one or more second carriers. For example, a timing adjustment parameter can be used for a timing adjustment amount or a timing adjustment ratio of a second carrier. Table 2 shows an example of an indication value used for a timing adjustment parameter group.

[0170]

[0171] Table 2

[0172] For example, when the indication value is 01, the timing adjustment parameter group includes a timing adjustment amount A, which can be used for timing adjustment of all second carriers or for timing adjustment of a specific second carrier among multiple second carriers.

[0173] For example, timing adjustment A, timing adjustment B, timing adjustment C, and timing adjustment D can each correspond to different second carriers, or they can correspond to the same second carrier in different scenarios.

[0174] Any row in Table 2 can be used alone or in combination with other rows.

[0175] In this embodiment of the disclosure, timing adjustment parameters of multiple second carriers can be indicated at once through a second information field, thereby further reducing signaling overhead.

[0176] like Figure 3A As shown, this disclosure provides an information processing method, which is executed by an NTN device, the method comprising:

[0177] S2110: Send configuration information; wherein the configuration information indicates at least a first carrier; the first carrier is a carrier aggregation or dual-connection alternative carrier; the first carrier includes: multiple carriers from different non-terrestrial network NTN devices; and / or multiple carriers from the same NTN device.

[0178] The NTN device can be an airborne NTN device. This airborne device can be an NTN access device located in the air or an NTN airborne relay device.

[0179] This configuration information can be an RRC message, a MAC message, or a DCI message, etc.

[0180] By sending configuration information, the UE can select a second carrier from multiple alternative first carriers for carrier aggregation or dual connectivity. In this way, UEs accessing the NTN can also increase transmission bandwidth and improve transmission rate based on carrier aggregation and / or dual connectivity.

[0181] In some embodiments, the configuration information includes:

[0182] First carrier information, indicating the first carrier;

[0183] First-time information indicates the availability time of the first carrier.

[0184] For example, the first carrier information may include at least one of the following:

[0185] Carrier identifier, wherein one carrier identifier indicates a first carrier;

[0186] Carrier group identifier, wherein a carrier group identifier indicates a carrier group, and a carrier group includes one or more carriers;

[0187] A carrier set identifier, wherein a carrier set identifier indicates a carrier set, a carrier set may include: one or more carrier groups, or one or more carriers.

[0188] As another example, the first carrier information may include: frequency information of the first carrier. For example, the frequency information may indicate the carrier's frequency point and / or subcarrier spacing, etc.

[0189] In summary, the first carrier information can be any information that can determine the first carrier.

[0190] In some embodiments, the configuration information may include first carrier information separately, and the availability time of each first carrier may be confirmed according to the protocol or determined according to default rules; alternatively, the UE may consider the time period between receiving the configuration information and the preset signaling as the availability time of the first carrier. The preset signaling may indicate carriers whose first carriers can no longer be used.

[0191] The first time information can be any information that can determine the availability time of the first carrier. This first time information can be optional information in the configuration information.

[0192] For example, the first time information may include duration information. For instance, after receiving the configuration information, the UE may consider the time at which the configuration information is received as the start time of the first carrier's available time. Since the duration information indicates the available duration, the start time offset in the time domain by an amount equal to the available duration indicated by the duration information can determine the end time of the first carrier's available time.

[0193] As another example, the first time information may include: start time information. The start and end time information respectively indicates the start and end times of the available time of the first carrier.

[0194] Again, by way of example, the first time information may include: termination time information, indicating the end time of the available time. In this case, the start time of the available time may be determined according to predefined rules such as protocol agreements, or determined by a start instruction sent by the NTN device.

[0195] For example, the availability time of the first carrier can be determined based on a preset area such as the tracking area (TA) or cell group where the UE is currently located. The UE may move within this preset area, and different UEs may be located at different points within the preset area; for example, some UEs may be located at the edge of the preset area, while others may be located in the middle. Therefore, the time range during which UEs at different locations can use the first carrier to communicate with the network side varies.

[0196] In some instances, NTN can provide continuous or discontinuous coverage of the ground. If NTN provides discontinuous coverage, some areas on the ground may not have NTN network signal coverage during certain time periods. The aforementioned first time information can be the time range within which the network signal transmitted by the NTN device to which the first carrier belongs can cover a preset area.

[0197] This disclosure provides an information processing method, executed by an NTN device, the method comprising:

[0198] Receive indication information, wherein the indication information indicates that the NTN device determines a second carrier for UE carrier aggregation or dual connectivity; the second carrier is a carrier of the NTN device.

[0199] It is worth noting that this embodiment can be executed alone or in conjunction with other methods. Figure 3A The illustrated embodiments are implemented in combination. With Figure 3A When combining embodiments as shown, the second carrier may be part or all of the first carrier indicated by the configuration information.

[0200] This indication information comes from the UE. NTN equipment can receive RRC messages, MAC layer messages, or uplink control information that contain this indication information.

[0201] In some embodiments, the indication information indicates the second carrier;

[0202] In some embodiments, if the indication information directly indicates the second carrier, then the UE directly informs the NTN device of the second carrier it has selected through the indication information.

[0203] In some other embodiments, the indication information indicates at least the first carrier other than the second carrier. In this embodiment, the indication information is equivalent to indirectly indicating the second carrier.

[0204] For example, the indication information may include second carrier information.

[0205] In one embodiment, the second carrier information may include: a carrier identifier.

[0206] The carrier identifier can indicate a second carrier, or a first carrier other than the second carrier. Here, the first carrier other than the second carrier can be referred to as the third carrier. If the carrier identifier indicates a third carrier, the NTN device, after receiving the indication information, will determine the second carrier based on the configuration information and the indication information.

[0207] In another embodiment, the second carrier information may include: a carrier set identifier and / or frequency information, which can be used to determine a second carrier, or a first carrier other than the second carrier.

[0208] This frequency information may include the frequency point number and / or the BWP number, etc.

[0209] In some embodiments, the indication information further includes:

[0210] The second time information indicates the time range during which the UE uses the second carrier.

[0211] The second time information may be: the UE determines the time period for the second carrier to be used for carrier aggregation and / or dual connectivity based on its own location, the operating trajectory information of the NTN device and / or the first time information, and uses the second time information to indicate the time period.

[0212] For example, the time period indicated by the second time information may be a sub-time period of the time period indicated by the first time information, and / or the time period indicated by the second time information may be partially within the time period indicated by the first time information and partially outside the time period indicated by the first time information.

[0213] In summary, the time period indicated by the second time information can be the time period during which the second carrier can be used for UE carrier aggregation and / or establishing dual connectivity. This facilitates subsequent scheduling of UE carrier aggregation and / or dual connectivity by the NTN device based on the second time information.

[0214] like Figure 3B As shown, this disclosure provides an information processing method, which is executed by an NTN device, the method comprising:

[0215] S2210: Send timing adjustment information, wherein the timing adjustment information is used to adjust the timing amount corresponding to one or more second carriers.

[0216] The second carrier may be the UE's serving carrier. The serving carrier may include the primary cell carrier and / or the secondary cell carrier.

[0217] For example, the second carrier may be a carrier for the UE to perform carrier aggregation and / or establish dual connectivity.

[0218] The timing adjustment information may include the timing adjustment amount and / or the timing adjustment ratio.

[0219] This timing adjustment information can be sent by the NTN device to the UE for timing adjustment of UE transmission based on carrier aggregation and / or dual connectivity.

[0220] For example, sending timing adjustment information includes:

[0221] Send scheduling information containing the timing adjustment information and scheduling instructions;

[0222] The scheduling instruction is used to schedule the transmission of the UE.

[0223] The scheduling instruction can be a scheduling instruction for uplink transmission and / or a scheduling instruction for downlink transmission of the UE.

[0224] The scheduling instruction may be a scheduling instruction for PUSCH transmission and / or PUCCH transmission; or, the scheduling instruction may be a scheduling instruction for PDSCH transmission and / or PDCCH transmission.

[0225] By including timing adjustment information and scheduling instructions together in the scheduling information, the NTN device carries timing adjustment information when performing transmission scheduling. This allows the UE to schedule uplink and / or downlink transmissions according to the timing adjustment information and the transmission scheduling instructions, thereby saving signaling overhead.

[0226] For example, the scheduling information can be carried in the DCI, so that the timing of the UE's use of each second carrier can be dynamically and in a timely manner through the DCI.

[0227] In some embodiments, the timing adjustment information includes one or more first information fields;

[0228] In some embodiments, the timing adjustment information includes one or more first information fields;

[0229] One of the first information fields is used to indicate the timing adjustment parameters of one or more second carriers, that is, the information indicated by the first information field is the same for the timing adjustment parameters of multiple second carriers.

[0230] The first information field may include one or more bits. A bit value in the first information field may indicate a timing adjustment parameter.

[0231] Thus, if the UE is configured with X second carriers, the timing adjustment information may include Y first information fields. Here, X can be any positive integer, and Y is a positive integer less than or equal to X.

[0232] For example, a first information field corresponds to a second carrier, so that the NTN device can flexibly adjust the timing of each second carrier according to the movement of each NTN device and / or changes in the wireless environment.

[0233] For example, one of the first information fields is used to indicate one of the timing adjustment parameters. This timing adjustment parameter can be used for some or all of the second carriers, in which case it is applicable to the adjustment of multiple second carrier systems. For example, if the NTN equipment to which the multiple second carriers belong is of the same type of airborne equipment, then the adjustment of the timing amount corresponding to the multiple second carriers can be indicated by a single first information field. The type of airborne equipment is adapted to the satellite type; for example, if the satellites corresponding to the multiple second carriers are all geostationary satellites, low-Earth orbit satellites, and / or high-Earth orbit satellites, then the adjustment of the timing amount corresponding to the multiple second satellites can be indicated by a single first information field.

[0234] For example, the timing adjustment parameter may be: the adjustment ratio of the timing amount, and / or the adjustment of the timing amount.

[0235] In some embodiments, the timing adjustment information includes a second information field;

[0236] Any indication value carried in the second information field corresponds to a timing adjustment parameter group; wherein, the timing adjustment parameter group includes one or more timing adjustment parameters; any timing adjustment parameter in the timing adjustment parameter group corresponds to one or more of the second carriers.

[0237] The timing adjustment parameter can be either a timing adjustment percentage or a timing adjustment amount.

[0238] For example, a timing adjustment parameter group may include a timing adjustment parameter. This timing adjustment parameter can be used to adjust the timing amount of all second carriers.

[0239] Furthermore, by way of example, a timing adjustment parameter group may include one or more timing adjustment parameters. A timing adjustment parameter can be used to determine the timing amount of one or more second carriers. By way of example, a timing adjustment parameter can be used for the timing adjustment amount or timing adjustment ratio of a second carrier. The embodiments of this disclosure provide a scheduling method for multiple satellites or multiple beams of a single satellite serving a UE in a satellite communication scenario, which can efficiently perform data scheduling and improve the data transmission rate of the UE.

[0240] In the embodiments disclosed herein, it is assumed that a satellite operates on one carrier wave. Of course, based on the same principle, a satellite can also operate on multiple carrier waves.

[0241] The UE receives configuration information from the base station and determines the aggregated carrier information. The configuration information includes at least frequency range information and / or identification information of the candidate carriers. This candidate carrier is also known as the alternative carrier, or the aforementioned first carrier.

[0242] In one embodiment, the UE receives configuration information from the base station to determine aggregated carrier information. The configuration information may be carried by higher-layer signaling (such as RRC signaling), MAC CE, or physical-layer signaling such as DCI. For example, the UE receives configuration information carried by the base station's RRC signaling to determine a candidate carrier set, and activates a portion of the carriers in the second carrier set via higher-layer signaling (such as MAC CE). The UE performs data scheduling on the determined portion of the carriers. Further, the configuration information also includes information about the available time range of the first carrier.

[0243] In one embodiment, the UE receives configuration information from the base station, determines a second carrier set and available time information, determines the identifier information of the carriers to be actually aggregated, and reports the identifier information of the actually aggregated carriers to the base station. The base station determines the carriers to be aggregated based on the information reported by the UE.

[0244] In one embodiment, the UE receives configuration information from the base station, determines the ephemeris information of the satellite corresponding to the second carrier, and if the UE determines that the first satellite does not meet the aggregation conditions, it reports the second satellite or reports an indication to deactivate the first satellite. The satellite here refers to one of the aforementioned NTN devices.

[0245] In some cases, when the base station updates the satellites corresponding to carriers available for carrier aggregation, the UE re-receives the base station's configuration information to determine the new satellite set. The determination that a satellite does not meet the aggregation conditions may be based on the altitude difference between the target satellite's orbital altitude and the orbital altitudes of the other satellites exceeding a predetermined range, or the timing difference between the timing of a satellite and the timing of other satellites exceeding a specific range.

[0246] The UE receives scheduling information from the base station to determine how to perform data transmission on multiple satellites.

[0247] The scheduling information carries timing adjustment information in the information field of the predefined or configurable location. This timing adjustment information can also be called timing value information.

[0248] The timing indication information is used by the UE to determine the timing adjustment of data transmission on different satellites. The bit length of the information field is predefined or defined by the base station's configuration information. The timing indication information can be uplink transmission timing adjustment parameters or downlink reception timing adjustment parameters. When the timing indication information indicates uplink transmission timing adjustment parameters, the UE needs to adjust its uplink transmission timing according to the timing indication information when performing uplink transmission for the corresponding satellite. When the timing indication information indicates downlink reception timing adjustment parameters, the UE needs to adjust its downlink data reception timing according to the indication information when performing downlink data reception for the target satellite.

[0249] The UE receives configuration information from the base station to determine the configuration set of timing indication information. For example, the configuration information determines the timing amount to be used through the information field, as shown in Table 3.

[0250]

[0251] Table 3

[0252] Furthermore, when data transmission on multiple satellites can be scheduled simultaneously using a single scheduling message, the information field can determine timing adjustments on multiple satellites using either individual or joint instructions.

[0253] In the case of individual instructions, the scheduling information contains multiple independent information fields, each indicating timing adjustment parameters for a satellite. The UE determines the timing adjustment parameters for the satellite according to predefined rules. The timing adjustment parameters carried in this information field can be used to adjust the timing of one or more carriers of a satellite.

[0254] In the case of joint instruction, the UE determines the timing adjustment parameters for multiple satellites through an information field. The UE receives the timing adjustment parameters from the base station, determines the timing relationship to be used based on the information field, and determines the final timing amount to be used based on the timing relationship. The UE determines the timing adjustment parameters for multiple satellites based on predefined rules, as shown in Table 4.
