[0136] The embodiments disclosed herein can be applied to Non-terrestrial Networks (NTN), Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Narrow Band-IoT (NB-IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0137] In some embodiments, a non-terrestrial network (NTN) is an important technology introduced by the 5th generation mobile communication system (5G). It provides wireless resources through satellites (or UAS platforms, where UAS stands for unmanned aircraft system) instead of ground base stations, as shown in Figure 1A. The link between the satellite and the terminal is called the service link.

[0138] In NTN, uplink capacity enhancement is considered for the following reasons in order to serve more users simultaneously:

[0139] 1. Limited frequency band resources are available for NTN;

[0140] 2. Satellites cover a larger cell radius, allowing for more users within a single cell compared to terrestrial networks;

[0141] 3. The transmission distance between the terminal and the satellite is relatively long. Under the premise of limited terminal transmission power, in order to improve cell coverage and transmission performance, the NTN network often needs to perform more blind retransmissions, which will greatly waste spectrum resources and reduce spectrum efficiency.

[0142] Therefore, we consider using multi-user multiplexing based on orthogonal cover code (OCC) to enhance uplink capacity.

[0143] The terminal can pre-compensate for time and frequency drift caused by the satellite's motion relative to the Earth.

[0144] In some embodiments, the terminal can perform pre-compensation for Doppler time drift and Doppler frequency drift caused by the satellite's motion relative to the Earth based on timing advance (TA) segmentation. In addition, the terminal can report the time gap required for pre-compensation based on its own capabilities. This is mainly because NB-IoT modules in traditional terrestrial networks (TN) undergo hardware and software optimization to save terminal costs. Such terminals require a certain physical adjustment delay when adjusting TA; therefore, reserving a certain time gap helps reduce the cost and implementation complexity of NTN NB-IoT terminals. During the time gap, the terminal does not transmit or receive uplink or downlink data.

[0145] In some embodiments, the aforementioned time interval not only reduces implementation complexity but also prevents signal overlap between segments when the TA2 of the next TA segmentation is greater than the TA1 of the current TA segmentation. In other words, the terminal will not perform any uplink transmissions during the aforementioned time interval.

[0146] In some embodiments, it is assumed that the uplink channel of the last slot transmitted by the terminal before the TA adjustment is located at slot#n, and the start time of the next segmentation of the terminal after the TA adjustment is: slot#n + time gap, where slot#n is the time determined based on the new TA.

[0147] It should be noted that even if no uplink transmission is performed within the time interval used for TA pre-compensation, this time interval is still counted within the transmission mapping resources of the uplink channel.

[0148] In summary, in some embodiments, one issue to consider for OCC multiplexing of narrowband uplink channels is that although the time interval between TA segments is not transmitted in the uplink channel, it is still included in the uplink channel transmission resources. Therefore, the impact of the time interval between segments on OCC multiplexing needs to be considered. Inappropriate multiplexing methods may disrupt the orthogonality between the data of two UEs. As an example, as shown in Figure 1B, assume that there are 4 UEs in the current user group performing slot-based OCC multiplexing, the OCC sequence length (OCC length = 4), the OCC sequence used by the current UE is (1, -1, -1, 1), the TA segment length is 8 slots (TA seg. = 8 slots), and the time interval is 2 slots (N_gap = 2 slots). That is, the positions of the 9th and 10th slots in Figure 1B are TA segments. The time interval between segmentations results in OCC multiplexing on the time-domain resources corresponding to the length of the second OCC sequence. Since some slots (the 9th and 10th slots) have their data dropped, orthogonal multiplexing between multiple users cannot be achieved (i.e., -1, -1, 1 are not orthogonal to the remaining three values ​​of the OCC sequences of other users). Therefore, an effective solution needs to be considered to address the problem of the orthogonality of multi-user multiplexing being violated due to the time interval between segments.

[0149] The information transmission method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0150] Figure 2A is an interactive schematic diagram of an information sending method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to an information sending method, which includes:

[0151] In step S2101, network device 101 sends the first information.

[0152] In some embodiments, terminal 102 receives the aforementioned first information.

[0153] In some embodiments, the first information is used to configure the terminal 102 to transmit time-frequency domain resources corresponding to the narrowband uplink channel.

[0154] In some embodiments, the first information described above is used to indicate at least one of the following: available time-domain resources; available frequency-domain resources.

[0155] In some embodiments, the time-domain and / or frequency-domain resources indicated by the first information above include the time interval between every two timing advance (TA) segments.

[0156] In some embodiments, the time-domain and / or frequency-domain resources indicated by the first information above do not include the time interval between every two TA segments.

[0157] In some embodiments, the name of the first information is not limited, and it may be, for example, “resource indication”, “resource configuration”, “resource allocation”, “time domain resource allocation”, “frequency domain resource allocation”, etc.

[0158] In step S2102, network device 101 sends the second information.

[0159] In some embodiments, terminal 102 receives the aforementioned second information.

[0160] In some embodiments, the second information described above is used to configure the terminal 102 to perform time-frequency offset pre-compensation based on the timing advance TA segment.

[0161] In some embodiments, the second information described above may include at least one of the first parameter and the second parameter.

[0162] In some embodiments, the first parameter is used to indicate the length of the time interval between every two TA segments, wherein the time interval is not used for terminal 102 to transmit data.

[0163] Optionally, the length of the time interval indicated by the second parameter can be a time-domain symbol, a time slot, or a subframe.

[0164] In some embodiments, the second parameter described above is used to indicate the length of each TA segment.

[0165] In some embodiments, the name of the second information is not limited, and may be, for example, “configuration information”, “uplink configuration”, “TA segment configuration”, “uplink segment configuration”, “Radio Resources Control (RRC)”, etc.

[0166] In some embodiments, the first parameter mentioned above can be configured using the Information Element (IE) "uplinkSegmentedPrecompensationGaps-r17".

[0167] In some embodiments, the second parameter described above can be configured using the information element "npusch-TxDuration-r17(NPUSCH transmission duration)" or "nprach-TxDuration-r17(NPRACH transmission duration)".

[0168] In some embodiments, terminal 102 may also send third information, which indicates the minimum length of the time interval between every two TA segments supported by terminal 102.

[0169] Optionally, the minimum length of the time interval indicated by the third information can be a time-domain symbol, a time slot, or a subframe.

[0170] In some embodiments, the name of the aforementioned third information is not limited, and it may be, for example, "capability information", "terminal capability", "segmented pre-compensation interval", etc.

[0171] In some embodiments, the aforementioned third information can be configured using the information element "ntn-SegmentedPrecompensationGaps-r17 (NTN segmented precompensation interval)".

[0172] In some embodiments, network device 101 may determine the second parameter to be sent to terminal 102 based on the aforementioned third information.

[0173] In some embodiments, the length of the time interval indicated by the first parameter is greater than or equal to the length of the time interval indicated by the third information.

[0174] In step S2103, terminal 102 sends a narrowband uplink channel based on OCC multiplexing.

[0175] In some embodiments, network device 101 receives the aforementioned narrowband uplink channel based on OCC multiplexing.

[0176] In some embodiments, the aforementioned narrowband uplink channel includes at least one of the following: Narrow-band Physical Uplink Shared Channel (NPUSCH); Narrow-band Physical Random Access Channel (NPRACH).

[0177] In some embodiments, the NPUSCH described above includes at least one of the following: a single-tone NPUSCH; or a multi-tone NPUSCH.

[0178] In some embodiments, the NPRACH described above includes at least one of the following: single-tone NPRACH; multi-tone NPRACH.

[0179] In some embodiments, terminal 102 can transmit the aforementioned narrowband uplink channel based on OCC multiplexing, based on first information and first and second parameters in second information. Terminal 102 can determine the time-frequency domain resources corresponding to the narrowband uplink channel based on the first information and first and second parameters in the second information. The time-frequency domain resources corresponding to the narrowband uplink channel do not include the aforementioned time interval. Furthermore, the first and second parameters are the same for multiple terminals within the same user group. The same user group refers to a user group using the same OCC multiplexing, meaning that multiple terminals within the same user group transmit the narrowband uplink channel using the same time-frequency domain resources.

[0180] Optionally, the terminal 102 performing OCC multiplexing of the narrowband uplink channel expects that the first and second parameters of multiple terminals belonging to the same user group are the same, wherein the time-frequency domain resources corresponding to the narrowband uplink channel transmitted by multiple terminals in the same user group are the same.

[0181] Optionally, terminal 102 may also send third information, which indicates the minimum length of the time interval between every two TA segments supported by terminal 102.

[0182] Optionally, the minimum length of the time interval indicated by the third information can be a time-domain symbol, a time slot, or a subframe.

[0183] Optionally, network device 101 may determine the second parameter to be sent to terminal 102 based on the aforementioned third information.

[0184] Optionally, the length of the time interval indicated by the second parameter is greater than or equal to the length of the time interval indicated by the third information.

[0185] That is, the time-frequency domain resources indicated by the first information above for the transmission of the narrowband uplink channel can be postponed based on the time interval between the TA segments, and the modulation symbols of the narrowband uplink channel transmitted by the terminal 102 based on OCC multiplexing will also be postponed.

[0186] Furthermore, the OCC sequence will cover the time slots where data is actually transmitted, but the time domain resources corresponding to the time interval will not be overwritten with the values ​​in the OCC sequence.

[0187] As an example, the above embodiment can be illustrated in Figure 2B. Assume that the current user group has 4 UEs performing slot-based OCC multiplexing, the OCC sequence length is 4, the OCC sequence used by the current UE is (1,-1,-1,1), the TA segment length is 8 slots (TA seg. = 8 slots), and the time interval is 1 slot (N_gap = 1 slot). That is, the positions of slots 9, 18, and 27 in Figure 2B are all time intervals between TA segmentations. The positions of the above time intervals are not included in the time-frequency domain resources corresponding to narrowband uplink channel transmission.

[0188] In some embodiments, terminal 102 can transmit the aforementioned narrowband uplink channel based on OCC multiplexing, based on first information and first and second parameters in second information. The length of the OCC sequence used by terminal 102 is determined based on the first and second parameters, and the time-domain length of each OCC multiplexing block. The time-frequency domain resources corresponding to the narrowband uplink channel may include the aforementioned time interval. Furthermore, the first and second parameters are identical for multiple terminals within the same user group. The same user group refers to a user group with the same OCC multiplexing, and multiple terminals within the same user group transmit narrowband uplink channels with identical time-frequency domain resources.

[0189] Optionally, terminal 102 uses the original OCC sequence on OCC multiplexing blocks that do not include the aforementioned time interval, and uses a newly added OCC sequence on OCC multiplexing blocks that include the aforementioned time interval.

[0190] Optionally, the terminal 102 performing OCC multiplexing of the narrowband uplink channel expects that the first and second parameters of multiple terminals belonging to the same user group are the same, wherein the time-frequency domain resources corresponding to the narrowband uplink channel transmitted by multiple terminals in the same user group are the same.

[0191] In other words, when the upper terminal 102 transmits a narrowband uplink channel based on OCC multiplexing, it can design a new OCC sequence of a new length (e.g., an OCC sequence of length 3, etc.) based on the position of the aforementioned time interval.

[0192] As an example, the above method can be illustrated in Figure 2C. Assume the UE performs slot-based OCC multiplexing, the configured OCC sequence length is 4, and the current UE uses the OCC sequence (1, -1, -1, 1) in the time domain for each OCC multiplexing block. The TA segment length is 8 slots (TA segment = 8 slots), and the time interval is 2 slots (N_gap = 2 slots). That is, slots 9, 10, 19, and 20 in Figure 2C represent the time interval between TA segmentations. Based on this, the 4 OCC multiplexing blocks occupying the first 8 slots do not include this time interval, so the original OCC sequence (1, -1, -1, 1) can be used. Of the four OCC multiplexed blocks occupying time slots 9-16, including this time interval, the data on the OCC multiplexed block occupying time slots 9-10 was dropped. Therefore, the remaining three OCC multiplexed blocks need to use a new OCC sequence of length 3 to maintain orthogonality with other terminals. Furthermore, in the case described in the example above, the maximum number of users that can be included in this user group is 3, which is determined by the minimum length of the OCC sequence used.

[0193] Optionally, a new OCC sequence of length can be designed by generating a cyclic shift sequence. For example: sequence#0 = [s(0), s(1), s(2), ..., s(k)], where k = 0, ..., M-1, s(k) = exp(j*2pi*k / M), where M is the length of the OCC; further, for the k-th value of sequence#i, we have: s(k) = s((k+i)modM). That is, first determine one sequence (sequence length M), and the remaining M-1 sequences can be obtained by cyclic shifting the sequence, thus constructing an orthogonal sequence.

[0194] In some embodiments, terminal 102 does not expect the first parameter to be included in the second information. Terminal 102 can transmit the narrowband uplink channel based on OCC multiplexing based on the first information and the second information.

[0195] Optionally, the terminal 102 performing OCC multiplexing of the narrowband uplink channel does not expect the network device 102 to configure the time interval between segments when performing time-frequency offset pre-compensation based on TA segments.

[0196] Optionally, the time interval between every two TA segments is set to 0.

[0197] Optionally, there is no time interval between any two TA segments.

[0198] Optionally, terminal 102 may choose not to send third information to network device 101, that is, not to report the segmentation interval capability.

[0199] Optionally, when terminal 102 does not send third information to network device 101, network device 101 defaults to the length of the aforementioned time interval being 0.

[0200] In some embodiments, terminal 102 does not expect the second information to include the first parameter and the second parameter. Terminal 102 can send the aforementioned narrowband uplink channel based on OCC multiplexing based on the first information.

[0201] Optionally, the terminal 102 performing OCC multiplexing of the narrowband uplink channel may not use time-frequency offset pre-compensation based on TA segmentation and may not expect the network device 102 to configure the relevant parameters of the uplink segmentation for it.

[0202] Optionally, the terminal 102 that performs OCC multiplexing of the narrowband uplink channel may employ time-frequency offset pre-compensation based on time slots.

[0203] Optionally, terminal 102 may choose not to send third information to network device 101, that is, not to report the segmentation interval capability.

[0204] Optionally, when terminal 102 does not send third information to network device 101, network device 101 defaults to the length of the aforementioned time interval being 0.

[0205] In some embodiments, terminal 102 can transmit the aforementioned narrowband uplink channel based on OCC multiplexing, based on first information and first and second parameters in second information. The time-frequency domain resources corresponding to the narrowband uplink channel may include the aforementioned time interval. The OCC multiplexing is based on repetition of the narrowband uplink channel; or, the OCC multiplexing is based on a redundant version (RV) of the narrowband uplink channel.

[0206] Optionally, the terminal 102 that performs time-frequency offset pre-compensation based on TA segmentation can use repetition-based OCC multiplexing or RV-based OCC multiplexing.

[0207] In some embodiments, terminal 102 can transmit the aforementioned narrowband uplink channel based on OCC multiplexing, based on first information and first and second parameters in second information. The time-frequency domain resources corresponding to the narrowband uplink channel may include the aforementioned time interval. The aforementioned OCC multiplexing is based on multiplexing multiple time slots.

[0208] Optionally, the terminal 102 that performs time-frequency offset pre-compensation based on TA segments can employ OCC multiplexing based on multiple time slots.

[0209] Optionally, the value of the first parameter can be a slot; or, the value of the first parameter can be a symbol; or, the terminal 102 does not expect the first parameter to be included in the second information.

[0210] Optionally, terminal 102 may send third information to network device 101, the third information being used to indicate the minimum length of the time interval between every two TA segments supported by terminal 102, the minimum length of the time interval supported by terminal 102 being one time domain symbol or one slot.

[0211] Optionally, the length of the time interval indicated by the first parameter is greater than or equal to the length of the time interval indicated by the third information.

[0212] Optionally, terminal 102 may choose not to send third information to network device 101, that is, not to report the segmentation interval capability.

[0213] Optionally, when terminal 102 does not send third information to network device 101, network device 101 defaults to the length of the aforementioned time interval being 0.

[0214] Optionally, in the above embodiments, the terminal 102 performing narrowband uplink channel OCC multiplexing may consider performing time-frequency offset pre-compensation based on TA segmentation, and may be configured with time intervals between segments. However, there are limitations on the OCC multiplexing methods applicable to different time interval parameters. For example, if the time interval length is one slot, it may be applied at most to repetition-based OCC multiplexing, or RV-based OCC multiplexing, or OCC multiplexing based on multiple slots. If the time interval length is one symbol, it can be applied to repetition-based OCC multiplexing, RV-based OCC multiplexing, OCC multiplexing based on multiple slots, OCC multiplexing based on a single slot, and so on.

[0249] Figure 5 is a flowchart illustrating an information transmission method according to an embodiment of the present disclosure. As shown in Figure 5, the method involved in this embodiment of the present disclosure is used in a communication system 100, and the method includes:

[0250] In step S5101, network device 101 sends first information to terminal 102. The first information is used to configure the time-frequency domain resources corresponding to the narrowband uplink channel.
