In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN.

[0113] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0114] In some embodiments, a core network device may be a single device comprising one or more network elements, or it may be multiple devices or a group of devices, each comprising all or part of the aforementioned one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Protocol Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0115] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0116] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A.

[0117] The embodiments disclosed herein can be applied to 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), 6th generation mobile communication system (6G), 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, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0118] Optionally, for the evolution of future cellular communication systems, the convergence of terrestrial networks (TN) and non-terrestrial networks (NTN) is a potential research direction. Based on this technology, network coverage can be expanded, providing a seamless service experience. In the scenario of TN and NTN network convergence, TN and NTN can achieve optimized resource utilization through spectrum sharing technology. That is, one possible evolutionary direction is that the Internet of Things Non-terrestrial Network (IoT-NTN) shares the spectrum resources of IoT-NT devices under the TN network to maximize resource utilization.

[0119] Optionally, in the communication system, an orthogonal cover code (OCC) technique is introduced for the narrowband physical uplink shared channel (NPUSCH) in the Internet of Things Non-terrestrial Network (IoT NTN) system to enable multi-user multiplexing transmission on the same time-frequency resources, thereby achieving uplink capacity enhancement.

[0120] Optionally, in the embodiments of this disclosure, "orthogonal coverage code (OCC) multiplexing transmission of the first channel" can be understood as follows: when different terminals transmit the first channel, the first channel of each terminal is weighted using the OCC sequence corresponding to that terminal's first channel. Different terminals correspond to different OCC sequences for their first channels; therefore, the weighted first channels obtained after weighting the first channel of each terminal based on the OCC sequence are different. Furthermore, each terminal can transmit its weighted first channel to the network device on the same time-frequency resource. When the network device receives the weighted first channels transmitted by each terminal on the same time-frequency resource, it can perform inverse weighting based on the OCC sequences corresponding to the first channels of each terminal to determine the first channel of each terminal. This achieves OCC multiplexing transmission of multiple terminals on the same time-frequency resource, improving resource utilization and realizing uplink capacity enhancement and system expansion. Under the premise of limited time-frequency resources and limited terminal transmission power, it can support more terminals for uplink transmission, improving uplink transmission efficiency.

[0121] Optionally, the first channel described above can be, for example, a Narrowband Physical Uplink Shared Channel (NPUSCH). NPUSCH can be, for example, a Narrowband Physical Uplink Shared Channel NPUSCH format 1.

[0122] Optionally, the time-domain resource allocation method for NPUSCH is explained as follows: The time-domain resources occupied by NPUSCH transmission can be determined based on the following parameters:

[0123] (1)N RU This indicates the number of Resource Units (RUs). It can be indicated by the Resource assignment field carried in the Downlink Control Information format N0 (DCI format N0) via a row in Table 1 below. Table 1 shows the number of Resource Units allocated to NPUSCH.

[0124] Table 1

[0125] (2)N Rep The number of repetitions is indicated by the Repetition Number field carried in DCI format N0 through a row in Table 2. Table 2 shows the number of repetitions assigned to NPUSCH.

[0126] Table 2

[0127] The number of slots and symbols occupied by a single RU is determined by the terminal by looking up the RU table based on the number of allocated subcarriers for multi-tone transmission. For single-tone transmission, the number of slots occupied by a single RU is fixed at 16.

[0128] Optionally, for single-tone transmission, as shown in Table 3 below, Table 3 illustrates the time-domain resource allocation for single-tone transmission. It shows the number of slots and the number of symbols per slot for different subcarrier spacings (SCS).

[0129] Table 3

[0130] The allocation of frequency domain resources for single-tone frequencies includes:

[0131] For SCS at 3.75 kHz (kilohertz): I sc (I sc (The subcarrier indicator field takes values ​​of 0, ..., 47, and occupies one subcarrier in the frequency domain;)

[0132] For 15kHz SCS: I sc =0, ...,11, the frequency domain occupies one subcarrier.

[0133] Optionally, for multi-tone transmission, as shown in Table 4 below, Table 4 illustrates the time-domain resource allocation for multi-tone. Table 4 shows the number of subcarriers, the number of slots, and the number of symbols per slot corresponding to a 15kHz SCS.

[0134] Table 4

[0135] Table 5 shows the frequency domain resource allocation for multi-tone applications. Rows 12-18 are used for multi-tone frequency domain resource allocation. sc This indicates the set of subcarriers allocated. Reserved indicates reserved bits.

[0136] Table 5

[0137] Optionally, unlike the uplink transmission of LTE and NR systems, Narrowband Internet of Things (NB-IoT) terminals do not transmit Sounding Reference Signals (SRS). However, for in-band deployment, the uplink transmission of NB-IoT terminals needs to circumvent the transmission of SRS in the LTE system. Therefore, to address the collision between the uplink transmission of NB-IoT terminals and the SRS transmission of LTE, the following conflict resolution method is introduced:

[0138] When the `npusch-AllSymbols-r13` parameter (or alternatively, the `npusch-AllSymbols` parameter) is configured as false, it indicates that NPUSCH overlaps with LTE SRS transmission. In this case, when the NB-IoT terminal maps NPUSCH to a resource element (RE), NPUSCH transmission will no longer occur on the Single Carrier-Frequency Division Multiple Access (SC-FDMA) symbols overlapping with SRS. However, the overlapping symbols will still be counted within the NPUSCH resources.

[0139] When npusch-AllSymbols-r13 (or the npusch-AllSymbols parameter) is configured as true, or when npusch-AllSymbols-r13 (or the npusch-AllSymbols parameter) is not configured, it means that all symbols assigned to NPUSCH can be used for NPUSCH transmission.

[0140] Optionally, when the uplink transmission of the NB-IoT terminal overlaps with the SRS transmission of LTE, the network device can indicate the resource location of SRS in LTE to the NB-IoT terminal through the srs-SubframeConfig parameter in the Radio Resource Control (RRC) signaling, so that the NB-IoT terminal can perform punching operation.

[0141] Alternatively, the SRS can be, for example, a cell-specific channel sounding reference signal (SRS).

[0142] Optionally, for LTE SRS, time-frequency domain resource mapping can be performed in the following manner. The method for determining LTE SRS frequency domain resources is explained below:

[0143] For example, the number of resource blocks (RBs) occupied in the frequency domain can be indicated by Table 6 below, where m SRS,b and N b In the values ​​b = 0, 1, 2, 3, the uplink bandwidth is... The range of values ​​for is: Among them, C SRS Indicates SRS bandwidth configuration, m SRS,b N represents the number of RBs used for transmitting SRS. b This indicates the number of partitions for the SRS transmission resources.

[0144] Table 6

[0145] For example, the number of resource blocks (RBs) occupied in the frequency domain can be indicated by Table 7 below, where the uplink bandwidth value is... The range of values ​​for is:

[0146] Table 7

[0147] Optionally, the above C SRS It can be configured through the cell-level parameter srs-BandwidthConfig, B SRS This can be configured via the terminal-level parameter `srs-Bandwidth`. Based on this, the number of RBs occupied by the SRS sent by the terminal can be determined. For example, if the network device (eNB) indicates C... SRS =0, then in B SRS When the value is 0 to 3, the number of RBs occupied by a terminal (UE) transmitting SRS is shown in Figure 1B. Figure 1B is a schematic diagram of the number of RBs occupied by a terminal transmitting SRS in an embodiment of this disclosure.

[0148] Optionally, within an RB, SRS resource mapping can also be performed through a comb structure, supporting a number of users {2, 4} for comb mapping.

[0149] Optionally, the method for determining LTE SRS time-domain resources is explained as follows:

[0150] In the time domain, the subframe location of cell-specific SRS can be determined by the srs-SubframeConfig parameter broadcast by the network device (eNB) via system messages. This srs-SubframeConfig parameter is indicated in one row of Table 8. For IoT-NTN, only frame structure type 1 SRS needs to be considered. Table 8 shows the SRS subframe configuration for frame structure type 1.

[0151] Table 8

[0152] Alternatively, T can be selected from a specific row in Table 8. SFC (Configured period), transmission offset (i.e., Δ) SFCThe subframe position for transmitting SRS can be determined using the following formula:

[0153] Where, n s For slot indexing, one slot in an LTE system occupies 7 time-domain symbols. For example, when the srs-SubframeConfig indicator is set to 7, it indicates that the SRS transmission period is 5 subframes. SRS is transmitted in the first and second subframes within each period. Furthermore, within a subframe, SRS is only transmitted on the last time-domain symbol of each subframe. The function represents the floor function, and mod() represents the modulo function.

[0154] Optionally, as shown in Figure 1C, which is a schematic diagram of a resource mapping method, taking a single-tone 3.75kHz SCS as an example, assume that {w0, w1} are mapped to time-domain symbols {symbol#0, symbol#1} respectively. The data symbols transmitted on time-domain symbol symbol#1 are the spread (i.e., repetition) of the data symbols transmitted on symbol#0. When symbol#0 overlaps with the SRS and is dropped, the data symbols transmitted by the two terminals on the symbol pair {symbol#0, symbol#1} will no longer be orthogonal. For example, UE#0 needs to transmit {1, -1} and UE#1 needs to transmit {1, 1}. Because the transmission on symbol#0 is dropped, UE#0's transmission becomes {NA, -1} and UE#1's transmission becomes {NA, 1}. The orthogonality of the data transmission of the two UEs on the two symbols is destroyed, and the network device cannot resolve the overlapping data symbols of the two UEs on symbol#2. This will affect the transmission performance of orthogonal coverage code (OCC) multiplexing transmission in the channel. The resource mapping method for DMRS in Figure 1C for a single-tone 3.75kHz SCS is only an example and is not intended to be limiting.

[0155] Figure 2A is an interactive schematic diagram of a communication control method according to an embodiment of the present disclosure. As shown in Figure 2A, the embodiment of the present disclosure relates to a communication control method, which can be used in a communication system 100, and is not limited thereto. The above method includes:

[0156] In step S2101, the network device sends first information, which includes: first indication information and second indication information.

[0157] The first information is used to determine the first time-domain resource. The first time-domain resource is used to transmit the first channel based on orthogonal coverage code (OCC). The first time-domain resource may include several time-domain symbols, and the terminal can use the first time-domain resource corresponding to several time-domain symbols to transmit the first channel based on orthogonal coverage code (OCC).

[0158] Optionally, in some embodiments, the terminal may be, for example, an NB-IoT terminal, and there is no limitation thereto.

[0159] Optionally, in some embodiments, the network device can send first information to the terminal, and the terminal can receive the first information and determine the first time domain resource based on the first information.

[0160] Optionally, in some embodiments, the first information can be carried in RRC signaling. The network device can send RRC signaling to the terminal, and the terminal can receive the RRC signaling and obtain the first information from the RRC signaling to determine the first time domain resource based on the first information.

[0161] Optionally, in some embodiments, the first information may include both first indication information and second indication information. The number of first information pieces can be one or more, and they may be contained within the same first information piece: both first indication information and second indication information. Alternatively, different first information pieces may each contain both first indication information and second indication information. For example, first information A contains first indication information, and first information B contains second indication information. There is no limitation in this regard.

[0162] The first indication information is used to configure or activate the first item. The first item indicates that the first channel is transmitted based on OCC multiplexing. Optionally, in some embodiments, if the first item is configured or activated, it indicates that the network device instructs the terminal to transmit the first channel based on OCC multiplexing.

[0163] Optionally, in some embodiments, the network device can instruct the terminal to transmit the first channel based on OCC multiplexing by sending first information to the terminal, including first indication information in the first information. Optionally, in some embodiments, the terminal can receive the first information sent by the network device, and the first information may include the first indication information, then the terminal knows that it needs to transmit the first channel based on OCC multiplexing based on the indication from the network device.

[0164] The second indication information indicates the number of time-domain units, which is used to determine the third time-domain resource. The third time-domain resource refers to the time-domain resource configured by the network device for the terminal. The terminal can determine the first time-domain resource actually used to transmit the first channel based on the third time-domain resource configured by the network device. Optionally, in some embodiments, the third time-domain resource configured by the network device may conflict with the time-domain resource mapped to the first signal. Therefore, to ensure the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel, the terminal can determine the first time-domain resource actually used to transmit the first channel to improve the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel.

[0165] Optionally, in some embodiments, the second indication information may specifically indicate the number of time domain units (e.g., time slots). The network device may also indicate the starting position of the resource to the terminal. The terminal calculates the third time domain resource by combining the starting position and the number of time domain units, and determines whether to directly use the third time domain resource to send the first channel in accordance with certain rules. For details, please refer to the following embodiments.

[0166] Optionally, in some embodiments, the first channel is a format 1 narrowband physical uplink shared channel (NPUSCH). This effectively improves the transmission performance of format 1 NPUSCH multiplexing using orthogonal coverage code (OCC).

[0167] Optionally, in some embodiments, the transmission type of the first channel includes at least one of the following: single-tone transmission; multi-tone transmission. This ensures the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel under various transmission types, thereby effectively expanding communication application scenarios and improving communication transmission performance.

[0168] Optionally, in some embodiments, the subcarrier spacing (SCS) of the first channel includes at least one of the following: 3.75 kHz; 15 kHz. This allows for a first channel applicable to various possible subcarrier spacings, ensuring good transmission performance when transmitting first channels with various possible subcarrier spacings based on OCC multiplexing, effectively expanding communication application scenarios.

[0169] Optionally, in some other embodiments, step S2101 may not be performed, that is, the network device may not send the first information to the terminal, and the terminal may determine the first information based on the protocol agreement, without any restrictions.

[0170] In step S2102, the terminal determines the third time domain resource based on the first instruction information and the second instruction information.

[0171] The third time domain resource refers to the time domain resource configured by the network device for the terminal. The terminal can determine the first time domain resource used to actually transmit the first channel based on the third time domain resource configured by the network device for the terminal.

[0172] Optionally, in some embodiments, when the terminal determines that the first information contains the first indication information, it learns that the first channel needs to be transmitted based on OCC multiplexing.

[0173] Optionally, in some embodiments, the second indication information may specifically indicate the number of time domain units (e.g., slots). The terminal may determine the starting position of the resource (e.g., indicated by a network device) and then calculate the third time domain resource by combining the starting position and the number of time domain units. There are no restrictions on this.

[0174] Optionally, in this embodiment, an application can be made under the following preconditions: the terminal does not support being simultaneously configured or activated for the first and second content items; and / or, the terminal does not expect to be simultaneously configured or activated for the first and second content items; and / or, the protocol stipulates that the simultaneous configuration or activation of the first and second content items for the terminal is not allowed; wherein, the configuration or activation of the first content item indicates that the first channel is transmitted based on OCC multiplexing; the configuration or activation of the second content item indicates that the third time-domain resources allocated for the first channel overlap with the second time-domain resources. This effectively avoids resource overlap between the uplink transmission of the NB-IoT terminal and the SRS transmission of LTE, thereby significantly improving the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel, increasing resource utilization, enhancing uplink capacity and expanding system capacity, supporting more terminals for uplink transmission, and improving uplink transmission efficiency.

[0175] Alternatively, in some embodiments, the aforementioned "preconditions" may be agreed upon by an agreement, and there are no restrictions on this.

[0176] The configuration or activation of the second item indicates an overlap between the third time-domain resources allocated to the first channel and the second time-domain resources. Optionally, in some embodiments, the second item is configured or activated, for example, by the aforementioned npusch-AllSymbols-r13 parameter (or alternatively, the npusch-AllSymbols parameter). That is, when the npusch-AllSymbols-r13 parameter (or alternatively, the npusch-AllSymbols parameter) is configured as false, it indicates an overlap between NPUSCH and LTE SRS transmission, which is not restrictive.

[0177] The second time-domain resource is used to map the first signal. The first signal is, for example, a Channel Sounding Reference Signal (SRS). The first signal can be transmitted by other terminals in the LTE system. For example, the second time-domain resource refers to the time-domain resource mapped by the LTE SRS transmission. The LTE SRS transmission can be transmitted by other terminals in the LTE system, which are different from the "NB-IoT terminal" in this embodiment.

[0178] Optionally, in some embodiments, the first signal is a cell-specific channel sounding reference signal (SRS). This effectively avoids resource overlap between the terminal's first channel orthogonal coverage code (OCC) multiplexing transmission and the SRS transmission in LTE, significantly reducing interference introduced by SRS transmission to the first channel's OCC multiplexing transmission, thereby improving the transmission performance of the first channel's OCC multiplexing transmission.

[0179] In other words, in this embodiment, the network device may not configure or activate the first and second items simultaneously for the terminal, or the protocol may stipulate that the terminal does not expect (or does not support, or does not allow) the simultaneous configuration or activation of the first and second items. In the above description, the first information may include first indication information, through which the network device instructs the terminal to transmit the first channel based on OCC multiplexing. In this case, the second item will not be configured or activated simultaneously for the terminal, indicating that the third time-domain resources allocated to the first channel do not overlap with the second time-domain resources. Therefore, the first time-domain resources actually used to transmit the first signal can be determined based on the following method.

[0180] In step S2103, the terminal determines the third time domain resource as the first time domain resource.

[0181] In other words, in this embodiment, the terminal can calculate the third time-domain resource based on the second indication information sent by the network device, and know that the network device has indicated the first indication information, thus knowing that the first channel is transmitted based on OCC multiplexing. Furthermore, if the terminal does not expect (or does not support, or does not allow) the simultaneous configuration or activation of the first and second items, then if the first item has already been configured or activated for the terminal, the second item will not be configured or activated simultaneously. In this case, it indicates that the third and second time-domain resources do not overlap, and the terminal can directly determine the third time-domain resource as the first time-domain resource to use the first time-domain resource to transmit the first channel. Therefore, the efficiency of determining the first time-domain resource can be significantly improved, supporting improved transmission efficiency of the first channel.

[0182] In step S2104, the terminal sends the first channel according to the first time domain resource.

[0183] Optionally, in some embodiments, after determining the third time-domain resource as the first time-domain resource, the terminal can use the first time-domain resource to transmit the first channel. For example, the terminal can transmit the first channel based on NPUSCH of OCC multiplexing transmission format 1 on the first time-domain resource. This ensures that there is no overlap between the first and second time-domain resources. The second time-domain resource is used to transmit the first signal, which can effectively avoid the overlap between the terminal's orthogonal coverage code OCC multiplexing transmission of the first channel and the transmission of the first signal, greatly reducing the interference introduced by the first signal transmission to the orthogonal coverage code OCC multiplexing transmission of the first channel, thereby improving the transmission performance of the orthogonal coverage code OCC multiplexing transmission of the first channel.

[0184] The communication control method disclosed in this embodiment may include at least one of steps S2101 to S2104. For example, steps S2101, S2102, S2103, and S2104 may be implemented as independent embodiments, steps S2101+S2102 may be implemented as independent embodiments, steps S2102+S2103 may be implemented as independent embodiments, steps S2101+S2102+S2103 may be implemented as independent embodiments, steps S2102+S2103+S2104 may be implemented as independent embodiments, and so on, but are not limited thereto.

[0185] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0186] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0187] In this embodiment, the network device sends first information, which includes first indication information and second indication information. The terminal determines a third time-domain resource based on the first and second indication information, and uses the third time-domain resource as the first time-domain resource. Based on the first time-domain resource, it then sends a first channel. This significantly improves the efficiency of determining the first time-domain resource, supporting improved transmission efficiency of the first channel. Furthermore, it ensures that the first and second time-domain resources do not overlap. The second time-domain resource is used to transmit the first signal, ensuring that the orthogonal coverage code (OCC) multiplexing transmission of the first channel does not overlap with the first signal transmission. This greatly reduces interference introduced by the first signal transmission to the orthogonal coverage code (OCC) multiplexing transmission of the first channel, thereby improving the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel.

[0188] It should be noted that in the following embodiments, the descriptions of the same or corresponding terms and method steps as in the above embodiments can be found in the above embodiments, and will not be repeated here.

[0189] Figure 2B is an interactive schematic diagram of a communication control method according to another embodiment of the present disclosure. As shown in Figure 2B, the embodiments of the present disclosure relate to a communication control method, which can be used in a communication system 100, and are not limited thereto. The above method includes:

[0190] In step S2201, the network device sends first information, which includes: first indication information and third indication information.

[0191] For a detailed description of the first information and the first instruction information, please refer to the above embodiments, which will not be repeated here.

[0192] The third indication information is used to configure or activate the second item. If the second item is configured or activated, it indicates that the third time-domain resources allocated to the first channel overlap with the second time-domain resources.

[0193] The second time-domain resource is used to map the first signal. The first signal is, for example, a Channel Sounding Reference Signal (SRS). The first signal can be transmitted by other terminals in the LTE system. For example, the second time-domain resource refers to the time-domain resource mapped by the LTE SRS transmission. The LTE SRS transmission can be transmitted by other terminals in the LTE system, which are different from the "NB-IoT terminal" in this embodiment.

[0194] The configuration or activation of the second item indicates an overlap between the third time-domain resources allocated to the first channel and the second time-domain resources. Optionally, in some embodiments, the second item is configured or activated, for example, by the aforementioned npusch-AllSymbols-r13 parameter (or alternatively, the npusch-AllSymbols parameter). That is, when the npusch-AllSymbols-r13 parameter (or alternatively, the npusch-AllSymbols parameter) is configured as false, it indicates an overlap between NPUSCH and LTE SRS transmission, which is not restrictive.

[0195] Optionally, in some embodiments, the third indication information may include the aforementioned npusch-AllSymbols-r13 parameter (or may be the npusch-AllSymbols parameter), and the npusch-AllSymbols-r13 parameter (or may be the npusch-AllSymbols parameter) is configured to be false.

[0196] Optionally, in this embodiment, an application can be made under the following precondition: the terminal supports the simultaneous configuration or activation of the first and second content items; and / or, the protocol stipulates that the terminal is allowed to simultaneously configure or activate the first and second content items; wherein, the configuration or activation of the first content item indicates that the first channel is transmitted based on OCC multiplexing; the configuration or activation of the second content item indicates that the third time-domain resources allocated for the first channel overlap with the second time-domain resources.

[0197] Alternatively, in some embodiments, the aforementioned "preconditions" may be agreed upon by an agreement, and there are no restrictions on this.

[0198] In other words, in this embodiment, the network device can simultaneously configure or activate the first and second content items for the terminal, or the protocol stipulates that the terminal supports (or allows) the simultaneous configuration or activation of the first and second content items. In the above description, the first information may include first indication information and third indication information, namely: the network device instructs the terminal to transmit the first channel based on OCC multiplexing using the first indication information, and the network device indicates, through the third indication information, that the third time-domain resource allocated for the first channel overlaps with the second time-domain resource. At this time, the terminal can determine the first time-domain resource actually used to transmit the first signal based on the following method.

[0199] In step S2202, the terminal determines the first time domain resource based on the first information.

[0200] Optionally, in some embodiments, the determination of the first time-domain resource based on the first information can be achieved using the following two methods:

[0201] In the first method, the first information further includes: second indication information, which indicates the number of time-domain units. The number of time-domain units is used to determine the third time-domain resource, and the third time-domain resource overlaps with the second time-domain resource. Determining the first time-domain resource based on the first information includes: calculating the first time-domain resource based on the number of time-domain units, wherein the first time-domain resource does not include the overlapping portion. This method can significantly improve the efficiency of determining the first time-domain resource and make the method of determining the first time-domain resource effectively applicable to various possible configurations or activation situations. In various communication scenarios, it ensures that the orthogonal coverage code (OCC) multiplexing transmission of the first channel of the terminal does not overlap with the first signal transmission, thereby improving the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel.

[0202] In other words, if the terminal learns that the network device has provided both first and third instruction information, that the first channel needs to be multiplexed based on OCC, and that the third time-domain resource overlaps with the second time-domain resource, then the terminal can calculate the third time-domain resource based on the second instruction information sent by the network device. Specifically, when calculating the third time-domain resource using the "number of time-domain units" indicated in the second instruction information, the terminal can skip the resources corresponding to the "overlapping portion," ensuring that the calculated first time-domain resource does not include the overlapping portion. In this first implementation, this is equivalent to postponing the transmission of the first channel.

[0203] For example, with LTE SRS, T SFCExamples are provided for NPUSCH with SCS of 2, offset of 0, and a single-tone 3.75kHz SCS. Figure 2C illustrates the time-domain resource location mapping in an embodiment of this disclosure when NPUSCH transmission is not delayed. Figure 2D illustrates the time-domain resource location mapping in an embodiment of this disclosure when NPUSCH transmission is delayed. In the delayed transmission method shown in Figure 2D, NPUSCH can be transmitted after the resource location of the collision symbol, that is, the starting position of NPUSCH transmission is delayed until after the "collision symbol". When determining the starting position of NPUSCH, based on the characteristic that the SCS of NPUSCH is 3.75kHz, the starting position of NPUSCH can be determined to be after the resource location of the "collision symbol", and at a resource location two symbols away. Figure 2E illustrates another time-domain resource location mapping in an embodiment of this disclosure when NPUSCH transmission is delayed. In the delayed transmission method shown in Figure 2E, the starting position of the NPUSCH can be kept unchanged, the resource position where the "Collision symbol" is located can be determined, and the first part of the NPUSCH can be transmitted. The resource position mapped to the first part of the NPUSCH can be before the resource position where the "Collision symbol" is located, and the transmission of the second part of the NPUSCH can be delayed. When determining the starting position of the second part of the NPUSCH, based on the characteristic that the SCS of the NPUSCH is 3.75kHz, the starting position of the second part of the NPUSCH can be determined to be after the resource position where the "Collision symbol" is located, and at a resource position two symbols apart. In the second delayed transmission method, it is equivalent to the NPUSCH being truncated during transmission.

[0204] In the second approach, the first information further includes a fourth indication information. This fourth indication information is used to determine the second time-domain resource. In the process of determining the first time-domain resource based on the first information, the terminal can determine a fourth time-domain resource that does not overlap with the second time-domain resource and designate it as the first time-domain resource. This significantly improves the efficiency and flexibility of determining the first time-domain resource, and makes the method of determining the first time-domain resource effectively applicable to various possible configurations or activation situations. In various communication scenarios, it ensures that the orthogonal coverage code (OCC) multiplexing transmission of the terminal's first channel does not overlap with the first signal transmission, thereby improving the transmission performance of the orthogonal coverage code (OCC) multiplexing transmission of the first channel.

[0205] In other words, if the terminal learns that the network device has indicated the first and third indications, that the first channel needs to be multiplexed based on OCC, and that the third time-domain resource overlaps with the second time-domain resource, then the terminal can determine the second time-domain resource mapped by the first signal based on the fourth indication sent by the network device. During this process, when the terminal calculates the third time-domain resource based on the "number of time-domain units" indicated by the network device, it can determine the fourth time-domain resource within the third time-domain resource that does not overlap with the second time-domain resource as the first time-domain resource. In the second implementation, this is equivalent to performing a drop operation on the transmission of the first channel.

[0206] For example, consider an NPUSCH with LTE SRS, Tsfc=2, offset=0, and a Single-tone 3.75kHz SCS. Figure 2F illustrates one time-domain resource location mapping when performing NPUSCH discarding in this embodiment. In Figure 2F, based on the NPUSCH's 3.75kHz SCS, a portion of the NPUSCH mapped to the resource locations of the four symbols before and after the "Collision symbol" can be discarded. Figure 2G illustrates another time-domain resource location mapping when performing NPUSCH discarding in this embodiment. In Figure 2G, a portion of the NPUSCH mapped to the resource location containing the "Collision symbol" can be discarded.

[0207] In step S2203, the terminal sends the first channel according to the first time domain resource.

[0208] Optionally, in some embodiments, after determining the first time domain resource based on the above method, the terminal can use the first time domain resource to send the first channel.

[0209] Optionally, in some embodiments, after determining the first time-domain resource, the terminal can use the first time-domain resource to transmit the first channel. For example, the terminal can transmit the first channel based on NPUSCH of OCC multiplexing format 1 on the first time-domain resource. This ensures that there is no overlap between the first and second time-domain resources. The second time-domain resource is used to transmit the first signal, which can effectively avoid the overlap between the terminal's orthogonal coverage code OCC multiplexing transmission of the first channel and the transmission of the first signal, greatly reducing the interference introduced by the first signal transmission to the orthogonal coverage code OCC multiplexing transmission of the first channel, thereby improving the transmission performance of the orthogonal coverage code OCC multiplexing transmission of the first channel.

[0210] Optionally, in some embodiments, when the terminal transmits the first channel according to the first time domain resources, it may discard at least some of the multiple information bits corresponding to the first channel, and / or perform rate matching processing on the multiple information bits corresponding to the first channel, and transmit the processed first channel according to the first time domain resources. This enables optimized transmission of the first channel, effectively improving the correctness of OCC-based multiplexing transmission of the first channel, and effectively ensuring communication transmission performance.

[0211] Optionally, in some embodiments, when the terminal transmits the first channel according to the first time domain resources, it may discard at least some of the information bits among the multiple information bits corresponding to the first channel, and transmit the processed first channel according to the first time domain resources.

[0212] Optionally, in some embodiments, when the terminal transmits the first channel according to the first time domain resources, it may perform rate matching processing on multiple information bits corresponding to the first channel, and transmit the processed first channel according to the first time domain resources.

[0213] The communication control method involved in the embodiments of this disclosure may include at least one of steps S2201 to S2203. For example, steps S2201, S2202, and S2203 may be implemented as independent embodiments, steps S2201+S2202 may be implemented as independent embodiments, steps S2202+S2203 may be implemented as independent embodiments, steps S2201+S2203 may be implemented as independent embodiments, etc., but not limited thereto.

[0214] In the embodiments disclosed herein, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations in other embodiments.

[0215] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0216] In this embodiment, the network device sends first information, which includes first indication information and third indication information. The terminal learns from the first indication information that it needs to transmit the first channel based on OCC multiplexing, and from the third indication information that the third time-domain resource overlaps with the second time-domain resource. The terminal can then determine the first time-domain resource based on the first information and transmit the first channel accordingly. In determining the first time-domain resource based on the first information, either the first or second method described above can be used. This significantly improves the efficiency of determining the first time-domain resource, supporting improved transmission efficiency of the first channel. Furthermore, ensuring that the first and second time-domain resources do not overlap, and that the second time-domain resource is used to transmit the first signal, ensures that the terminal's orthogonal coverage code OCC multiplexing transmission of the first channel does not overlap with the first signal transmission. This significantly reduces interference introduced by the first signal transmission to the orthogonal coverage code OCC multiplexing transmission of the first channel, thereby improving the transmission performance of the orthogonal coverage code OCC multiplexing transmission of the first channel.

[0217] Optionally, in some embodiments of this disclosure, the OCC of the first channel is mapped to a first time-domain resource. This effectively improves the correctness of OCC multiplexing transmission of the first channel, enabling network devices to parse data symbols transmitted by the terminal and improving communication transmission performance.

[0218] Optionally, in some embodiments of this disclosure, the terminal expects the number of available time-domain symbols in the first time-domain resources to meet a certain condition, wherein the available time-domain symbols are used for data transmission, and the data does not include: the first signal and the demodulation reference signal DMRS of the first channel. This effectively improves the resource utilization of the first channel based on OCC multiplexing transmission and effectively ensures the correct orthogonal coverage code OCC multiplexing transmission of the first channel, thereby improving the performance of the communication system.

[0219] Optionally, in some embodiments of this disclosure, the condition includes: mod(N, OCC length) = 0; where N represents the number of available time-domain symbols, OCC length represents the OCC length used by the terminal, and mod() represents the modulo function. This effectively improves the resource utilization of the first channel based on OCC multiplexing transmission and effectively ensures the correct orthogonal coverage code OCC multiplexing transmission of the first channel, thereby improving the performance of the communication system.

[0220] For example, using the first channel as a narrowband physical uplink shared channel NPUSCH (NPUSCH format 1) as an example, for a terminal performing NPUSCH format 1 OCC multiplexing, it is expected that the number of available time-domain symbols N will satisfy mod(N,OCC length) = 0, where N represents the number of available time-domain symbols, OCC length represents the OCC length used by the terminal, mod() represents the modulo function, and the data transmitted by the available time-domain symbols does not include: LTE SRS and NPUSCH demodulation reference signal (DMRS).

[0221] Optionally, in some embodiments of this disclosure, the number of available time-domain symbols in the first time-domain resources is determined to meet a condition based on the third time-domain resources allocated to the first channel and / or the period and transmission offset of the first signal. The available time-domain symbols are used for data transmission, and the data does not include the first signal and the DMRS of the first channel. Therefore, resource utilization of the first channel based on OCC multiplexing transmission can be ensured based on resource allocation, thereby supporting applications in personalized communication scenarios and enabling correct OCC multiplexing transmission of the first channel in various possible communication scenarios.

[0222] For example, taking the first channel as NPUSCH format 1, for a terminal performing NPUSCH format 1 OCC multiplexing, it can support NPUSCH format 1 resource allocation that satisfies mod(N,OCC length) = 0, or the related LTE SRS (an optional example of the first signal) period configuration and transmission offset. Specifically, for example, assuming that the transmission of NPUSCH format 1 of single-tone 3.75kHz SCS starts from subframe #0 in SFN#0, and the number of allocated resource units (RUs) is 1 (taking OCC spreading independently within all RUs in one repetition as an example), then it does not support resource configurations with an LTE SRS period configuration of 5 and transmission offsets of {0}, {1}, {0,1}, etc.

[0293] The following is an exemplary description of the above method.

[0294] Optionally, the following embodiments are available:

[0295] The example uses an IoT-NTN terminal.

[0296] To address the technical problem of potential collisions between uplink transmission of NB-IoT terminals and SRS transmission of LTE in this disclosure embodiment, at least one of the following methods can be used:

[0297] Optionally, in some embodiments, it is not supported to configure npusch-AllSymbols-r13 as false and NPUSCH format 1 OCC multiplexing simultaneously.

[0298] Optionally, in some embodiments, the IoT-NTN terminal does not expect to be configured with both npusch-AllSymbols-r13 set to false and NPUSCH format 1 OCC multiplexing simultaneously. Alternatively, the IoT-NTN terminal does not expect to have NPUSCH format 1 OCC multiplexing activated while npusch-AllSymbols-r13 is configured to false. Or, the IoT-NTN terminal does not expect to have npusch-AllSymbols-r13 set to false while NPUSCH format 1 OCC multiplexing is configured or activated.

[0299] Optionally, in some embodiments, it is permissible to configure npusch-AllSymbols-r13 to false and NPUSCH format 1 OCC multiplexing simultaneously. Further, various optional implementations are available:

[0300] Optionally, in some embodiments, implementation method one can be used: when the NPUSCH format 1 performing OCC multiplexing conflicts with LTE SRS on certain time domain symbols, postponing processing is performed on the transmission of NPUSCH format 1.

[0301] Optionally, in some embodiments, based on method one: when the LTE SRS conflicts with NPUSCH format 1 performing OCC multiplexing on some time-domain symbols, the corresponding resources are no longer counted as NPUSCH format 1 resources. That is, the transmission of NPUSCH format 1 will be delayed.

[0302] Optionally, in some embodiments, based on method one: OCC code mapping (cover) is performed on the resource where NPUSCH format 1 mapping is actually performed. That is, OCC code mapping (cover) skips the resource where the LTE SRS is located.

[0303] Optionally, in some embodiments, implementation method two can be used: when NPUSCH format 1 performing OCC multiplexing conflicts with LTE SRS on certain time domain symbols, the transmission of NPUSCH format 1 is dropped. That is, the resources on the corresponding time domain symbols will not be transmitted using NPUSCH format 1, but will still be treated as resources mapped by NPUSCH format 1. Two different processing methods can be used: dropping and rate-matching.

[0304] Optionally, in some embodiments, based on method two, the OCC code is mapped (covered) on the resource where NPUSCH format 1 mapping is actually performed, that is, the OCC code mapping (covered) will skip the resource where LTE SRS is located.

[0305] Optionally, in some embodiments, a possible situation is that the symbol length at the end of the time domain of NPUSCH format 1 for OCC multiplexing is insufficient for the OCC length, or the number of available time domain symbols N in NPUSCH format 1 does not satisfy: mod(N,OCC length)=0.

[0306] Based on this, the following optional implementation methods can be performed:

[0307] Optionally, in some embodiments, for IoT-NTN terminals performing NPUSCH format 1 OCC multiplexing, it is not expected that the configured number of available time-domain symbols N will not satisfy mod(N,OCC length) = 0, where N is the number of available time-domain symbols for data transmission after excluding LTE SRS / NPUSCH DMRS, etc. Alternatively, resource allocation for NPUSCH format 1 that does not satisfy mod(N,OCC length) = 0, or the associated periodic configuration of LTE SRS, is not supported. For example, assuming that the transmission of NPUSCH format 1 in single-tone 3.75kHz SCS starts from subframe #0 in SFN#0, and the number of allocated resource units (RUs) is 1 (taking OCC spreading independently within all RUs in one repetition as an example), then resource configurations with a periodic configuration of 5 for LTE SRS and transmission offsets of {0}, {1}, {0,1}, etc., are not supported.

[0308] Optionally, in some embodiments, the above-described optional implementation methods are applicable to OCC multiplexing multi-user multiplexing transmission modes for at least one of the following channels:

[0309] Single-tone NPUSCH format 1 with 3.75kHz SCS;

[0310] Single-tone NPUSCH format 1 with 15kHz SCS;

[0311] Multi-tone NPUSCH format 1.

[0312] The method provided in this disclosure can support the efficient operation of the NPUSCH format 1 OCC multiplexing mechanism in the IoT-NTN system, and can guarantee the link transmission performance and realize system expansion. Thus, under the premise of limited time and frequency resources and limited terminal transmission power, it can support more terminals to perform uplink transmission and improve uplink transmission efficiency.

[0313] This disclosure also provides embodiments of an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Alternatively, another apparatus is provided that includes units or modules for implementing the steps performed by a network device (e.g., a RAN) in any of the above methods.

[0314] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0315] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
