[0036] The embodiments of the present disclosure provide an information processing method, a terminal, a network device, a communication system, and a storage medium.
[0037] In a first aspect, an embodiment of the present disclosure proposes an information processing method, which is applied to a network device, including: sending first information, where the first information is used to indicate the timing advance of the UL transmission of the terminal; wherein the first information includes an offset value, and wherein the timing advance of the uplink UL transmission of the terminal is determined based on the offset value and the TA of the terminal.
[0038] In the above embodiment, the first information can be sent to the terminal through the network device to inform the terminal of the timing advance of the UL transmission; the terminal can perform uplink transmission at an appropriate time when using the TDD mode in the NTN, thereby reducing the occurrence of uplink and downlink confusion on the terminal side; for example, reducing the occurrence of a situation where the UL transmission time slot is ahead of the DL time slot that schedules the UL transmission.
[0039] In addition, the offset value can be carried by the first information so that the terminal can increase the offset value on the basis of TA (that is, shift the time unit of the offset value back on the time unit of TA), thereby reducing the uplink and downlink confusion on the terminal side without reconfiguring the switching point interval between the downlink and uplink of the terminal; in this way, the reduction of the uplink and downlink confusion on the terminal side can be achieved more conveniently, and the impact and complexity on the wireless communication standard can be reduced.
[0040] In combination with some embodiments of the first aspect, in some embodiments, sending the first information includes at least one of the following: a system message, an RRC, and a MAC CE.
[0041] In the above embodiment, the terminal can send the first information through multiple signaling methods, thereby being applicable to more application scenarios. In addition, the first information can be sent by multiplexing system messages, RRC signaling, or MAC CE, thereby improving the utilization rate of system messages, RRC signaling, or MAC CE.
[0042] In combination with some embodiments of the first aspect, in some embodiments, the offset value is for each base station, where the base station corresponds to at least one cell; or, the offset value is for each cell, where the cell corresponds to one or more terminals; or, the offset value is for each terminal.
[0043] In the above embodiment, the same offset value can be configured for the same base station, so that all terminals within the base station can determine the timing advance based on the offset value, thereby reducing the signaling overhead of configuring the offset value. Alternatively, the same offset value can be configured for terminals within the same cell, so that all terminals within the cell can determine the timing advance based on the offset value, thereby reducing the signaling overhead of configuring the offset value. Alternatively, the offset value can be configured for each terminal, thereby achieving personalized configuration and meeting the needs of the terminal.
[0044] In conjunction with some embodiments of the first aspect, in some embodiments, the UL transmission includes at least one of the following:

[0049] In combination with some embodiments of the first aspect, in some embodiments, the sum of the offset value and the first time is greater than or equal to TA; wherein the first time is the interval time between the downlink DL transmission and UL transmission of the terminal.
[0050] In the above embodiment, if the sum of the offset value and the first time is greater than or equal to TA, the UL and DL of the terminal will not be aligned in the time domain, thereby solving the problem of uplink and downlink confusion of the terminal, that is, the problem of UL transmission delay being ahead of the DL time slot for scheduling the UL transmission can be solved.

[0121] In some embodiments, the core network device may be a single device including a first network element, a second network element, etc., or may be a plurality of devices or a group of devices, each including all or part of the first network element and the second network element.

[0123] In some embodiments, the specific architecture of the NTN network is shown in Figure 1B. There are two types: transparent and regenerative. In a transparent architecture, the satellite performs transparent forwarding, meaning that communications between the base station and the user equipment (UE) are forwarded via the satellite. Generally, the NTN gateway and the base station are assumed to be very close together, so they can be roughly considered to be in the same location. In a regenerative architecture, a portion of the base station (Distributed Unit, DU) or the entire base station is located on the satellite, providing data processing capabilities. The user equipment (UE) is typically a terminal.
[0124] In some embodiments, timing advance (TA) is used for UE (i.e., UE uplink transmission, which is a negative offset between the start time of the UE receiving the downlink subframe and the start time of the uplink subframe transmission. To ensure the orthogonality of uplink transmission, the base station requires that the time at which signals from different UEs on the same subframe but different frequency domain resources arrive at the base station is substantially aligned. To ensure time synchronization on the receiving side (e.g., the base station side), the UE side needs to perform uplink time pre-compensation, i.e., timing advance. Optionally, the UE side in the NTN network fully compensates for uplink and downlink delays, specifically including the delay from the satellite to the reference point (RP) and the delay from the UE to the satellite; the location of the reference point can be any point on the satellite, base station, or feeder link. Optionally, the delay from the satellite to the reference point RP is indicated by the base station, and the delay from the UE to the satellite is calculated using the UE's global navigation satellite system (GNSS) positioning and satellite ephemeris.
[0125] In some embodiments, the NTN uplink timing advance calculation formula is as follows: TA =(N TA +N TA,UE-specific +N TA,common +N TA,offset )×T c Where, Tc is the time unit; N TA Based on the random access message MSG2 / MSGB and the timing advance command (Timing Advance Command) of the Media Access Control (MAC) control element (CE), the N TA In the Physical Random Access Channel (PRACH), it can be defined as 0; N TA,UE-specific is the delay from UE to satellite, the N TA,UE-specific It can be the delay measured by UE based on GNSS positioning and satellite ephemeris; N TA,common is the time delay from the satellite to the reference point, the N TA,common Can be notified via the network side; N TA,offset is a fixed offset. Optionally, T TA Support N TA,UE-specific 0 (ie, the reference point is on the satellite). Optionally, as shown in FIG1C , a schematic diagram of NTN parameters is provided; the NTN parameters include N TA,UE-specific and N TA,common wait.
[0126] In NTN, the TA value is large and may be greater than K0, K1, and K2, which will cause confusion in the timing relationship. For example, if the TA value is used in the timing advance, the UE's uplink (UL) transmission time slot will be ahead of the downlink (DL) time slot that schedules the UL transmission. Optionally, k0 refers to the time slot interval between the downlink control information (DCI) and the physical downlink shared channel (PDSCH) it schedules; k1 refers to the time slot interval between the PDSCH and its hybrid automatic repeat request-ACKnowledgement (HARQ-ACK) feedback; and k2 refers to the time slot interval between the uplink scheduled DCI and the physical uplink shared channel (PUSCH) it schedules. Therefore, a new offset value (K_offset) can be introduced. The UE's uplink transmission has an additional offset value (K_offset) on the original basis, which will avoid the problem of confusion in the UE's uplink and downlink timing relationship.
[0127] In some embodiments, the duplexing method used in the NTN is frequency division duplexing (FDD). Due to the large latency of the NTN, the timing advance in the NTN is also large, especially for the transparent satellite architecture currently under discussion. For example, when the satellite altitude is 600 kilometers (km), the UE needs to compensate for a TA value of at least 8 milliseconds (ms), which poses a significant challenge to the use of time division duplexing (TDD) technology in the NTN. For a regenerative satellite architecture, that is, when the gNB is located on the satellite, the TA value is significantly reduced. For example, when the gNB is located on a satellite at 600 km, the TA value is at least 4 ms. Furthermore, for high altitude platforms (HAPS), the TA value is relatively small, such as 0.13 ms for a 20 km altitude HAPS. Therefore, the use of TDD is more promising for low-orbit satellites, HAPS, and unmanned aerial vehicles (UAVs) in regenerative architectures.
[0128] In some embodiments, when the NTN uses TDD mode and the reference point (RP) is not on the gNB side, uplink and downlink interference may occur on the gNB side. For example, when the transmission delay (e.g., round-trip time (RTT)) between the UE and the gNB is 2 slots and the TA is 1 slot, the interference caused by TDD mode on the gNB side is shown in Figure 1D. In Figure 1D, "F" represents the uplink / downlink transition point interval (gap), which indicates the time interval between the uplink (UL) and downlink. In Figure 1D, when the transmission delay between the UE and the base station is 2 slots, the delay between the gNB DL to the UE DL is 1 slot, and the delay between the UE UL to the gNB UL is 1 slot. When the TA is 1 slot, the UE UL is one slot ahead of the UE DL. As a result, the n-frames of the gNB DL and gNB UL are misaligned. As shown in Figure 1D , the time slot corresponding to the UL marked by the oval circle on the gNB DL and the time slot corresponding to the UL marked by the circle on the gNB UL indicate that the gNB DL's understanding of UL (i.e., uplink transmission) in this gNB is inconsistent with the actual UL in the gNB UL. Furthermore, as can be seen from the box in Figure 1D , the time slot of the UL marked by the box in the gNB DL will be used for DL in the gNB UL, that is, the use of TDD in the NTN will cause interference to the uplink and downlink on the gNB side.
[0129] In some embodiments, when the NTN network uses TDD and the uplink and downlink frame alignment point is on the gNB, the TA value of the NTN network is significantly larger than that of the terrestrial network. Therefore, when TDD is used in the NTN network, the UE's timing advance (TA) may be too large, causing uplink and downlink confusion on the UE side. For example, when the transmission delay (RTT) between the UE and the gNB is 2 slots, the uplink and downlink transition point interval (gap) is 1 slot, and TA is equal to the RTT, the interference caused to the UE using TDD in the NTN using TDD is shown in Figure 1E. In Figure 1E, "F" represents the uplink and downlink transition point interval (gap). In Figure 1E, when the transmission delay between the UE and the base station is 2 slots, the delay between the gNB DL to the UE DL is 1 slot, and the delay between the UE UL to the gNB UL is 1 slot. When the TA is 2 slots, the UE UL is 2 slots ahead of the UE DL. Thus, the gNB DL and gNB UL frames are aligned. As shown in Figure 1E , the time slot corresponding to the UL marked by the oval circle on the UE DL and the time slot corresponding to the UL marked by the circle on the UE UL can be seen that the UL circled in the UE UL will be two time slots ahead of the UL circled in the UE DL; and as can be seen from the box in Figure 1E , the time slot of the UL marked by the box in the UE DL corresponds to the DL on the UE DL, that is, the use of TDD in the NTN will cause up and down confusion on the UE side.
[0130] Generally, the above-mentioned UL refers to the time slot corresponding to UL transmission, and DL refers to the time slot corresponding to DL transmission.
[0131] In some embodiments, since only FDD duplex mode is considered, K_offset is not used for Configured Grant Type 1 (CG1) and Configured Grant Type 2 (CG2) or some other UL transmissions; so when timing advance is applied to these UL transmissions, there will still be a problem of uplink and downlink confusion on the UE side.
[0132] Optionally, GC1: uplink transmission authorization is provided by the Radio Resource Control (RRC) layer, and the UE stores the configuration and uses it as authorization configuration.
[0133] Optionally, CG2: Uplink transmission authorization is provided by the Physical Downlink Control Channel (PDCCH), and the configuration is stored or cleared according to the indication of activation or deactivation of the configuration by the layer 1 signal (L1Signalling).

[0139] In some embodiments, the terminal receives a system message sent by a network device, wherein the system message includes first information.
[0140] In some embodiments, the network device sends RRC signaling to the terminal, wherein the RRC signaling includes the first information. Optionally, the RRC signaling can be any type of RRC signaling, such as an RRC configuration message or an RRC reconfiguration message.
[0141] In some embodiments, the terminal receives RRC signaling sent by the network device, wherein the RRC signaling includes first information.
[0142] In some embodiments, the network device sends a MAC CE to the terminal, where the MAC CE includes first information.
[0143] In some embodiments, the terminal receives a MAC CE sent by a network device, where the MAC CE includes first information.
[0144] In some embodiments, the first information is used to indicate a timing advance of UL transmission of the terminal. Optionally, the terminal performs UL transmission after the timing advance.
[0145] In some embodiments, the first information is used to indicate a timing advance of UE transmission of a terminal in the NTN.
[0146] In some embodiments, the name of the first information is not limited, and it can be, for example, configuration information, indication information, timing advance configuration information or indication information, etc.
[0147] Optionally, the timing advance is at least one time slot, for example, 1 time slot, 2 time slots, or 3 time slots.
[0148] Optionally, the timing advance is at least one symbol, for example, 1 symbol, 2 symbols, or 3 symbols.
[0149] Optionally, the timing advance is a third duration, which is any time, for example, 1 ms, 2 ms, or 5 ms.
[0150] Optionally, the name of the timing advance is not limited, and it can be, for example, advance time or timing advance value.
[0151] Optionally, the UL transmission of the UE may be a UL transmission of a first configured grant type. The first configured grant type may be configured grant type 1 (CG1) in the previous embodiment.
[0152] Optionally, the UL transmission of the UE may be a UL transmission of a second configuration authorization type. The second configuration authorization type may be configuration authorization type 2 (CG2) in the previous embodiment.
[0153] Optionally, the UL transmission of the UE may be a UL transmission that does not use an offset value, or the UE transmission may be a UL transmission that does not use a timing advance.
[0154] In some embodiments, the first information includes an offset value, and the timing advance is determined based on the offset value and the timing advance (TA).
[0155] Optionally, the timing advance is an advance time.
[0156] Optionally, the timing advance may be replaced by the first timing advance, and the TA may be replaced by the second timing advance.
[0157] Optionally, the timing advance may be replaced by the first advance time, and TA may be replaced by the second advance time.
[0158] Optionally, the timing advance can be the time required for the terminal to advance when aligning the timing of the base station in the NTN. For example, the uplink transmission (gNB UL) and downlink transmission (gNB DL) of the base station (gNB) are timing aligned, that is, the frames marked n in the gNB UL and gNB DL in Figure 1E are aligned. Furthermore, as shown in Figure 1E , there is a transmission delay between the gNB UL and the UE downlink transmission (UE DL). The UE uplink transmission timing advance (TA) needs to take into account the transmission delay from the UE to the satellite so that the uplink transmissions of different UEs can reach the gNB within a predetermined time range. For example, if the transmission delay is 2 time slots, the TA of the UE's uplink transmission is 2 time slots.
[0159] For example, when the NTN network uses TDD, the reference point is located on the gNB side, and an offset value (K_offset) is used; if the difference between the TA value and the offset value (K_offset) is less than or equal to the uplink / downlink switch point interval (i.e., K_offset + uplink / downlink switch point interval is greater than or equal to TA), the uplink / downlink confusion problem on the UE side can be resolved. For example, when the TA value is 2 time slots, K_offset is 1 slot, the uplink / downlink switch point interval is equal to 1 slot, and k1 is equal to 2 slots, the transmission of HARQ feedback for PDSCH can be shown in Figure 2B. In Figure 2B, "F" represents the uplink / downlink switch point interval (gap). In Figure 2B , when the transmission delay between the UE and the base station is two slots, the delay between the gNB DL and UE DL is one slot, and the delay between the UE UL and gNB UL is one slot. When the TA is two slots, the UE UL is two slots ahead of the UE DL. This ensures that the n frames of the gNB DL and gNB UL are aligned. Before the TA is increased by K_offset, this can be seen in Figure 1E . After K_offset is added to the TA, it can be seen as shown in Figure 2B; as shown in Figure 2B, the time slot corresponding to the UL marked by the oval circle on the UE DL and the time slot corresponding to the UL marked by the circle on the UE UL, the UL circled in the UE UL will be advanced by 1 time slot. And as shown in the box in Figure 2B, the time slot of the UL marked by the box in the UE DL corresponds to F on the UE DL, so the use of TDD in the NTN will not cause confusion in the uplink and downlink of the UE, that is, the use of the offset value (K_offset) can solve the problem of UE uplink and downlink confusion.
[0160] Optionally, the timing advance may be at least one time slot, at least one symbol, or a fourth time duration; the fourth time duration may be any time.

[0164] Optionally, the network device includes core network equipment and / or access network equipment, etc.; the access network equipment may include a base station.
[0165] Optionally, the offset value is specific to each cell, where each cell corresponds to one or more terminals.

For example, if the sum of the offset value and the first time is equal to TA, as shown in FIG2B , the UE DL corresponding to the first UL time slot of the UE UL is F, and no uplink or downlink confusion (or interference) is caused. If the sum of the offset value and the first time is greater than TA, then in FIG2B , the UE DL corresponding to the first UL time slot of the UE UL is also UL, and no uplink or downlink confusion (or interference) is caused.
[0173] Optionally, the first time is the interval time between downlink DL transmission and UL transmission of the terminal.
[0174] Optionally, the first time may be the uplink / downlink switching point gap in the previous embodiment.

[0176] Optionally, the first time may be at least one of the following: at least one time slot, at least one symbol, and a second time length. Optionally, the second time length may be any time; for example, the second time length may be 1ms, 3ms, or 5ms.
[0177] Step S2102: The network device sends second information to the terminal.
[0178] In some embodiments, the terminal receives second information sent by the network device.
[0179] In some embodiments, the second information is used by the terminal to determine the uplink and downlink transmission cycles, or the second information is used by the terminal to re-determine the uplink and downlink transmission cycles.
[0180] In some embodiments, the name of the second information is not limited, and it can be, for example, configuration information, or uplink and downlink transmission cycle configuration information, etc.
[0181] Optionally, the second information is used by the terminal to determine that when the uplink and downlink transmission period of the terminal is less than or equal to a predetermined duration, a predetermined multiple of the uplink and downlink transmission period is used for transmission.
[0182] Optionally, the second information is used by the terminal to determine that the first ratio is less than or equal to a predetermined ratio, and to use a predetermined multiple of the uplink and downlink transmission period for transmission, wherein the first ratio is the ratio of the terminal's UL transmission to the uplink and downlink transmission period.
[0183] Optionally, the predetermined duration may be a plurality of time slots, or a plurality of symbols, or a fifth duration. The fifth duration may be any duration, for example, 3 ms, 5 ms, or 10 ms.
[0184] Optionally, the predetermined duration may be configured by the network device, or the predetermined duration may be determined based on a user input operation, or the predetermined duration may be based on a protocol agreement.
[0185] Optionally, the predetermined multiple is an integer greater than 1. Optionally, the predetermined multiple is a real number greater than 1. For example, the predetermined multiple is 2, etc.
[0186] Optionally, the predetermined ratio is a value greater than 0 and less than or equal to 1. For example, the predetermined ratio is a value greater than or equal to 0.5 and less than or equal to 1.
[0187] Optionally, the predetermined ratio may be configured by the network device, or the predetermined ratio may be determined based on a user input operation, or the predetermined ratio may be based on a protocol agreement.
[0188] Step S2103: The terminal performs the first operation.
[0189] In some embodiments, the first operation includes performing UL transmission and / or determining an uplink and downlink transmission cycle.
[0190] In some embodiments, the terminal determines to perform UL transmission after a timing advance.
[0191] In some embodiments, when the uplink and downlink transmission period of the terminal is less than or equal to a predetermined duration, a predetermined multiple of the uplink and downlink transmission period is used for transmission; wherein the predetermined multiple is an integer greater than 1.
[0192] In some embodiments, the first ratio is less than or equal to a predetermined ratio, and transmission is performed using a predetermined multiple of uplink and downlink transmission cycles, wherein the first ratio is the ratio of the terminal's UL transmission to the uplink and downlink transmission cycles.
[0193] Exemplarily, as shown in FIG2C , the uplink and downlink transmission periodicity (DL-UL-Transmission Periodicity) of the terminal is 14 time slots, which is less than or equal to the predetermined duration, and the terminal re-determines the uplink and downlink transmission periodicity to be twice the previous uplink and downlink transmission periodicity.
[0194] For example, as shown in FIG2C , the time slot of the UL transmission of the terminal exceeds 2 time slots, the uplink and downlink transmission periodicity (DL-UL-Transmission Periodicity) is 14 time slots, and the first ratio of the terminal (approximately 0.143) is less than the predetermined ratio (for example, 0.5); the terminal re-determines the uplink and downlink transmission periodicity to be twice the previous uplink and downlink transmission period.
[0195] For example, if the UL transmission time originally transmitted by the terminal exceeds a predetermined duration, the terminal uses a predetermined multiple of the uplink and downlink transmission period for transmission. The predetermined duration may be a time unit such as a time slot, a symbol, or a second, a millisecond, or the like.
[0196] In some optional embodiments, the terminal determines the timing advance.

[0300] The present disclosure relates to an information processing method that takes into account the use of TDD in NTN. The method includes:
[0301] In some embodiments, for UL transmissions configured with Grant Type 1 (CG1) or Grant Type 2 (CG2) in Rel-17 and Rel-18, or other transmissions that do not use K_offset, a K_offset offset value is introduced; the UE's uplink transmission is incremented by the K_offset based on the original offset value, and the UE's timing advance is used in the time slot after the K_offset is incremented. Optionally, the K_offset is the offset value in the previous embodiment; the UE can be the terminal in the previous embodiment.
