[0154] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102.

[0155] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

[0156] In some embodiments, network device 102 may include at least one of access network device and core network device.

[0157] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0158] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. 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. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0159] 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.

[0160] 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).

[0161] 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.

[0162] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0163] 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).

[0164] Optionally, in a non-terrestrial network (NTN), uplink capacity enhancement can be performed to simultaneously serve more terminals. Reasons for uplink capacity enhancement may include at least one of the following: limited frequency band resources for the NTN network; satellite-covered cell radii are typically larger, resulting in more terminals within the same cell compared to a terrestrial network (TN); and the transmission distance between the terminal and the satellite is relatively long, requiring more blind retransmissions in the NTN network to improve cell coverage and transmission performance under limited terminal transmit power, thus wasting spectrum resources and reducing spectrum efficiency.

[0165] 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.

[0166] Optionally, if the terminal supports Demodulation Reference Signal (DMRS) bundling, it can report the duration of phase continuity that can be maintained during DMRS bundling to the network device (e.g., gNB). For example, the duration of phase continuity that can be maintained can be reported through the maxDurationDMRS-Bundling-r17 parameter. For example, n4 and n8 can be specified in the maxDurationDMRS-Bundling-r17 parameter, where n4 represents 4 slots and n8 represents 8 slots, without limitation.

[0167] Optionally, network devices (e.g., gNBs) can configure the window length of the phase continuity time domain window (TDW) for terminals that support DMRS-bundling functionality. The network device (e.g., gNB) can determine an appropriate time slot based on the value of the maxDurationDMRS-Bundling-r17 parameter reported by the terminal, and configure the number of time slots to the terminal via the pusch-TimeDomainWindowLength-r17 parameter.

[0168] Optionally, when the terminal transmits data via the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH) based on dmrs-bundling, it needs to maintain phase continuity. Specifically, the value of the pusch-TimeDomainWindowLength-r17 parameter configured by the network device (e.g., gNB) should not exceed the terminal's capabilities; that is, it should not exceed the duration reported by the terminal based on the maxDurationDMRS-Bundling-r17 parameter.

[0169] Optionally, when performing OCC demultiplexing, the receiver assumes that the channels between different time-domain resources to which the modulation symbol is spread are consistent. Therefore, when transmitting through a channel based on OCC multiplexing, the transmitter must ensure that the transmission on different time-domain resources within the OCC sequence length is phase continuous. That is, the terminal needs to determine a phase continuity maintenance window and maintain the phase continuity of the channel within the phase continuity maintenance window when transmitting the channel based on OCC multiplexing, so as to ensure that the network device can correctly perform OCC demultiplexing of the channel and improve communication performance.

[0170] Alternatively, in embodiments of this disclosure, the time window may also be referred to as a time domain window, time window, window, phase continuity maintenance window, etc.

[0171] Optionally, in the embodiments of this disclosure, the duration of the time window may also be referred to as the window length, window size, etc., and there is no limitation thereto.

[0172] Alternatively, in embodiments of this disclosure, the OCC sequence length may also be referred to as OCC length, OCC multiplexing user number, etc.

[0173] Alternatively, in embodiments of this disclosure, the indicator field may also be referred to as an indicator field, field, indicator value, parameter, etc.

[0174] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the embodiment of the present disclosure relates to a communication method that can be used in a communication system 100. The communication system 100 may include a terminal and a network device, which are not limited thereto. The above method includes:

[0175] Step S2101: The terminal sends the first information to the network device.

[0176] Optionally, in some embodiments, the terminal is, for example, a UE, and the network device is, for example, a base station (e.g., a gNB).

[0177] Optionally, in some embodiments, the first information can be used to enable the network device to determine the terminal's ability to maintain phase continuity. That is, the terminal can indicate its ability to maintain phase continuity by reporting the first information to the network device. The network device can then learn about the terminal's ability to maintain phase continuity by receiving the first information reported by the terminal.

[0178] Optionally, in some embodiments, the ability of the terminal to maintain phase continuity may be, for example, the terminal supporting at least one first duration for maintaining phase continuity, the OCC multiplexing method supported by the terminal, the OCC sequence length of the OCC multiplexing method supported by the terminal, etc., and there are no limitations on this.

[0179] Optionally, in some embodiments, the first information includes at least one of the following: first indication information, OCC multiplexing mode supported by the terminal, second indication information, and at least one first duration; wherein, the first indication information is used to indicate that the terminal has the ability to maintain phase continuity, the second indication information is used to indicate the OCC sequence length of the OCC multiplexing mode supported by the terminal, and the first duration is used for the terminal to maintain phase continuity during OCC multiplexing transmission of the first channel. Therefore, the terminal's ability to maintain phase continuity can be effectively indicated to the network device, enabling the network device to determine a first time window suitable for OCC multiplexing transmission of the first channel based on the terminal's ability to maintain phase continuity. Furthermore, the content included in the first information can be customized according to the communication scenario requirements, allowing for flexible application of multiple indication methods, thus effectively adapting to personalized communication scenarios and improving application flexibility.

[0180] Optionally, in some embodiments, the first indication information described above may be used to indicate the forward characteristics supported by the terminal (DMRS bundling based on PUSCH repetition type A (or DMRS-bundling for PUSCH repetition type A)), and / or the first indication information may also be used to indicate the second duration of phase continuity that the terminal can maintain during DMRS-bundling.

[0181] Optionally, in some embodiments, the terminal may report first indication information to the network device when reporting OCC multiplexing transmission of the supporting channel (e.g., NRPUSCHOCC multiplexing).

[0182] Optionally, in some embodiments, the first indication information includes at least one of the following: a first indication field and a second indication field; wherein the first indication field is used to indicate at least one second duration supported by the terminal, the second duration being used for the terminal to maintain phase continuity based on the demodulation reference signal (DMRS) bundling function, and the second indication field is used to indicate that the terminal supports the DMRS bundling function based on repetitive transmission type A. This ensures phase continuity when the terminal performs OCC multiplexing transmission of the channel, and also ensures that the network device can correctly schedule and decode the OCC multiplexing of the channel.

[0183] Optionally, in some embodiments, the first indication field may be, for example, the maxDurationDMRS-Bundling-r17 parameter.

[0184] Optionally, in some embodiments, the second indication field may be, for example, the dmrs-BundlingPUSCH-RepTypeA-r17 parameter.

[0185] For example, when a terminal reports support for OCC multiplexing transmission of a channel (e.g., NRPUSCHOCC multiplexing), it can report supported forward characteristics including: DMRS-bundlingforPUSCHrepetitiontypeA. Alternatively, when reporting support for OCC multiplexing transmission of a channel (e.g., NRPUSCHOCC multiplexing), the terminal can simultaneously report dmrs-BundlingPUSCH-RepTypeA-r17 and / or maxDurationDMRS-Bundling-r17. Based on this approach, phase continuity can be guaranteed when the terminal performs OCC multiplexing transmission of the channel, while ensuring that the network can schedule and correctly decode appropriate channel OCC multiplexing. In other words, in this approach, the terminal supports performing OCC multiplexing transmission of the channel (e.g., NRPUSCHOCC multiplexing) by reporting the dmrs-BundlingPUSCH-RepTypeA-r17 parameter and / or maxDurationDMRS-Bundling-r17 parameter.

[0186] Optionally, the interpretation of the value of the maxDurationDMRS-Bundling-r17 parameter can be found in the "Interpretation of Window Length Reported by Terminal" in the following embodiment, and there are no restrictions on this.

[0187] Optionally, in some embodiments, the OCC multiplexing methods supported by the terminal include at least one of the following: mapping a sequence value of an OCC sequence to at least one symbol; mapping a sequence value of an OCC sequence to one time slot; mapping a sequence value of an OCC sequence to at least two non-contiguous time slots, wherein the interval between two adjacent non-contiguous time slots mapped by the same sequence value is L-1 time slots, where L is the length of the OCC sequence; or mapping a sequence value of an OCC sequence to at least one symbol within a symbol group. This ensures the performance of OCC multiplexing transmission of the channel, thereby improving communication performance.

[0188] Alternatively, in some embodiments, the OCC multiplexing scheme may also be referred to as OCCscheme or OCCmultiplexingscheme.

[0189] Optionally, in some embodiments, when the terminal performs OCC multiplexing transmission of the channel, a sequence value of the OCC sequence can be mapped to at least one symbol. This OCC multiplexing transmission method can be referred to as symbol-level OCC multiplexing (Inter-symbol). In other embodiments, a sequence value of the OCC sequence can be mapped to a time slot. This OCC multiplexing transmission method can be referred to as slot-level OCC multiplexing (Inter-slot). Mapping a sequence value of the OCC sequence to a time slot can be, for example, assuming the OCC sequence length is 2, then OCCsequence = [w1, w2], where w1 or w2 represents the sequence value. Further, w1 can be mapped to the data symbol transmitted in slot 1, and w2 can be mapped to the data symbol transmitted in slot 2.

[0190] Optionally, in some embodiments, the slot-level OCC multiplexing method may also be, for example, mapping one sequence value of the OCC sequence to at least two non-contiguous time slots, wherein the interval between two adjacent non-contiguous time slots mapped by the same sequence value is L-1 time slots, where L is the length of the OCC sequence. This method may also be called Inter-2 slot.

[0191] Optionally, in some embodiments, a sequence value of an OCC sequence is mapped to at least one symbol within a symbol group, a method that may also be referred to as an Intra-symbol group.

[0192] Optionally, the aforementioned second indication information can be used to indicate the OCC sequence length of the OCC multiplexing method supported by the terminal. Optionally, since an OCC multiplexing method can correspond to one or more OCC sequence lengths, the terminal can indicate the OCC sequence length of the OCC multiplexing method supported by the terminal by reporting the second indication information to the network device.

[0193] Optionally, in some embodiments, the second indication information includes at least one of the following: at least one third indication field, a fourth indication field, and a fifth indication field; wherein, the third indication field is used to indicate whether the terminal supports one OCC sequence length of the OCC multiplexing method; the fourth indication field is used to indicate at least one OCC sequence length supported by the terminal among multiple OCC sequence lengths of the OCC multiplexing method; and the fifth indication field is used to indicate the maximum OCC sequence length supported by the terminal among multiple OCC sequence lengths of the OCC multiplexing method. Therefore, the terminal can select an appropriate reporting method to report the supported OCC sequence lengths, and the network device can effectively know the OCC sequence lengths supported by the terminal, thereby ensuring the reception performance of channel OCC multiplexing and improving communication performance.

[0194] Optionally, in some embodiments, the second indication information may include one or more third indication fields. Each third indication field is used to indicate the length of an OCC sequence in the OCC multiplexing method. The third indication field can be configured to a value indicating that the terminal supports the OCC multiplexing method for that OCC sequence length, or it can be configured to another value indicating that the terminal does not support the OCC multiplexing method for that OCC sequence length. There is no limitation on this. That is, by including at least one third indication field in the second indication information, the system can report whether the terminal supports each OCC sequence length separately.

[0195] Optionally, in some embodiments, the second indication information may include a fourth indication field, which may jointly indicate one or more OCC sequence lengths supported by the terminal. That is, by including a fourth indication field in the second indication information, at least one OCC sequence length supported by the terminal among multiple OCC sequence lengths of the jointly reported OCC multiplexing method can be achieved.

[0196] Optionally, in some embodiments, the second indication information may include a fifth indication field, which may indicate the maximum OCC sequence length supported by the terminal among multiple OCC sequence lengths of the OCC multiplexing method. That is, by including the fifth indication field in the second indication information, the maximum OCC sequence length supported by the terminal among multiple OCC sequence lengths of the reported OCC multiplexing method is achieved.

[0197] Optionally, in some embodiments, the OCC sequence length supported by the terminal described above may include at least one of the following: 2, 4, or 5. The unit of OCC sequence length can be "number". Thus, when the OCC sequence length is 2, 4, or 5, the transmission and reception performance of channel OCC multiplexing can be ensured, thereby improving communication performance.

[0198] Optionally, in some embodiments, the OCC multiplexing mode supported by the terminal is associated with a first duration; and / or, the OCC sequence length supported by the terminal is associated with a first duration; and / or, the subcarrier spacing (SCS) of the first channel is associated with a first duration; and / or, the number of subcarriers of the first channel is associated with a first duration. This allows the terminal to implicitly indicate the supported first duration to the network device by reporting the supported OCC multiplexing mode and / or OCC sequence length, or the network device can determine the first duration associated with the subcarrier spacing (SCS) of the first channel and / or the number of subcarriers of the first channel. The first duration is used to maintain phase continuity during the OCC multiplexing transmission of the first channel, thereby enabling the network device to configure a suitable first time window for the terminal based on the implicitly reported first duration. The first time window is used to maintain phase continuity during the OCC multiplexing transmission of the first channel.

[0199] Optionally, in some embodiments, the first channel described above may include at least one of the following: a Narrowband Physical Uplink Shared Channel (NPUSCH) of format 1 (or referred to as NPUSCH format 1), a Narrowband Physical Random Access Channel (NPRACH), or a Physical Uplink Shared Channel (PUSCH). This allows for the application of customized first channels, supporting the maintenance of phase continuity in the transmission of the first channel during various possible first channel OCC multiplexing transmissions, while ensuring that network devices can correctly schedule and decode various possible first channel OCC multiplexings.

[0200] Optionally, in some embodiments, the transmission type of NPUSCH in format 1 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.

[0201] Optionally, in some embodiments, the subcarrier spacing (SCS) of Format 1 NPUSCH includes at least one of the following: 3.75 kHz; 15 kHz. This first channel, applicable to various possible subcarrier spacings, ensures good transmission performance when transmitting the first channel with various possible subcarrier spacings based on OCC multiplexing, effectively expanding communication application scenarios.

[0202] For example, for OCC multiplexing, the window size for phase continuity maintenance supported by the terminal is bound to the OCC length corresponding to the OCC multiplexing method supported by the terminal. For example, by reporting the supported OCC multiplexing scheme and / or supported OCC length, the terminal can implicitly determine the window length of its phase continuity maintenance window. The supported OCC scheme and / or OCC length may include at least one combination of the following:

[0203] For PUSCH, the terminal may support at least one of the following OCC schemes and / or OCC lengths: Inter-slot, OCC2; Inter-slot, OCC4.

[0204] For NPUSCH, the terminal may support at least one of the following OCC schemes and / or OCC lengths:

[0205] For Multi-tone, it includes at least one of the following: Inter-slot, OCC2; Inter-2slot, OCC2; Inter-slot, OCC4; Inter-2slot, OCC4.

[0206] For Single-tone, it should include at least one of the following:

[0207] For a 3.75kHz SCS, it includes at least one of the following: Inter-symbol, OCC2; Inter-symbol, OCC4.

[0208] For a 15kHz SCS, it corresponds to at least one of the following: Inter-slot, OCC2; Inter-2slot, OCC2.

[0209] For NPRACH, the terminal may support at least one of the following OCC schemes and / or OCC lengths: Intra-symbol group, OCC2, OCC4, OCC5, etc.

[0210] For example, different terminals may support different OCC schemes. If a specific terminal supports a certain OCC scheme, it can support all OCC lengths under that OCC scheme. Furthermore, different terminals may support different OCC lengths (e.g., UE#1 supports OCC2, UE#2 supports OCC4, or UE#1 supports both OCC2 and OCC4, UE#2 supports OCC2). In this approach, the OCC length supported by the terminal can be determined through at least one of the following three methods:

[0211] Optionally, in some embodiments, the terminal can report to the base station using independent parameters (an optional example of the third indication field described above). For example, the terminal can report whether it supports OCC2 or OCC4 using an independent FG (an optional example of the third indication field described above). That is, OCC2 and OCC4 can be reported to the gNB separately using separate parameters. Taking Inter-slot OCC multiplexing as an example, a possible Radio Resource Control (RRC) reporting signaling design could include, for example, Inter-slot-occ2 ENUMERATED{supported} and / or Inter-slot-occ4 ENUMERATED{supported} in the RRC reporting signaling.

[0212] The “Inter-slot-occ2 ENUMERATED{supported}” above is an optional example of the third indicator field, used to indicate the OCC sequence length 2 (OCC2) under the OCC multiplexing mode (Inter-slot) supported by the terminal. “Inter-slot-occ4 ENUMERATED{supported}” is another optional example of the third indicator field, used to indicate the OCC sequence length 4 (OCC4) under the OCC multiplexing mode (Inter-slot) supported by the terminal.

[0213] Optionally, in some embodiments, the terminal may report multiple OCClength values. For example, the terminal reports the following (an optional example of the fourth indication field mentioned above): OCClength::=SEQUENCE{ OCC2 BOOLEANOPTIONAL, OCC4 BOOLEAN OPTIONAL};

[0214] Among them, based on the aforementioned content, the OCC sequence lengths supported by the joint instruction terminal are OCC2 and OCC4.

[0215] Optionally, in some embodiments, the terminal reports the longest supported OCClength value (an optional example of the maximum OCC sequence length mentioned above). For example, the terminal may report the following (an optional example of the fifth indication field mentioned above):

[0216] OCC length::=ENUMERATED{n2, n4};

[0217] In this mode, if the terminal reports support for OCClength=4, it implicitly indicates that the terminal also supports OCC2. Alternatively, if the terminal reports support for OCClength=4, it implicitly indicates that the terminal also supports OCC2 under the same OCC scheme (i.e., if the terminal reports a value of N, it implicitly reports that the terminal supports any OCC length less than or equal to N).

[0218] Optionally, the above-mentioned OCClength reporting method can be for the same OCCscheme, while different OCCschemes and / or the OCClength supported by the uplink multi-user multiplexing channel can be reported separately with independent parameters.

[0219] Optionally, in some embodiments, the terminal may include at least one first duration supported by the terminal in the first information. The first duration is used by the terminal to maintain phase continuity of the first channel OCC multiplexing transmission. That is, the terminal may report to the network device, through the first information, at least one supported first duration that can maintain phase continuity of the first channel OCC multiplexing transmission.

[0220] Optionally, in some embodiments, the terminal may report a new parameter to the network device to indicate at least one first duration supported by the terminal.

[0221] Optionally, in some embodiments, when reporting at least one first duration, the terminal may report the first duration based on at least one of a sixth indication field, a seventh indication field, an eighth indication field, and a ninth indication field. For example, the sixth indication field indicates a general first duration; the seventh indication field indicates a first duration associated with the subcarrier spacing (SCS); the eighth indication field indicates a first duration associated with the number of subcarriers; and the ninth indication field indicates a first duration associated with the OCC multiplexing method. Thus, the terminal can flexibly report one or more supported first durations using various possible methods, enabling the network device to effectively determine the terminal's ability to maintain phase continuity.

[0222] Optionally, in some embodiments, the terminal may include a sixth indication field in the first information to indicate a first duration, which may be common. For example, for a specific Narrowband Internet of Things Non-terrestrial Network (NB-IoT) terminal, for different OCC schemes (inter-symbol, inter-slot, inter-2-slot) supported by the terminal, a window length of a common phase continuity maintenance (an optional example of the aforementioned first duration) may be reported; or for different transmission channels (NPUSCH or NPRACH) transmitted by the terminal, a window length of a common phase continuity maintenance (an optional example of the aforementioned first duration) may be reported; or for different SCSs (3.75kHz SCS, 15kHz SCS) supported by the terminal... The terminal can report a window length for a common phase continuity maintenance (an optional example of the first duration mentioned above); or for different numbers of subcarriers (tones, e.g., single-tone, multi-tone (3, 6, 12)) supported by the terminal, it can report a window length for a common phase continuity maintenance (an optional example of the first duration mentioned above), without any restrictions.

[0223] Optionally, in some embodiments, the terminal may include a seventh indication field in the first information, which indicates a first duration associated with the subcarrier spacing (SCS). That is, the terminal may independently report the first duration associated with each different SCS.

[0224] For example, for NPUSCH format 1, a specific terminal can independently report the window length of supported phase continuity maintenance for different SCSs (an optional example of the first duration mentioned above). For instance, for a 15kHz SCS, the window length for reporting supported phase continuity maintenance is {n2, n4, etc.}. For a 3.75kHz SCS, the window length for reporting supported phase continuity maintenance is {symbol2, symbol4, etc.}, without restriction.

[0225] Optionally, in some embodiments, the terminal may include an eighth indication field in the first information, which indicates a first duration associated with the number of subcarriers. That is, the terminal may independently report the first duration associated with different numbers of subcarriers (tones).

[0226] For example, for NPSUCH format 1, a specific terminal can independently report the window length of the supported phase continuity maintenance for different tone numbers (an optional example of the first duration mentioned above).

[0227] Optionally, in some embodiments, the terminal may include a ninth indication field in the first information, which is used to indicate the first duration associated with the OCC multiplexing method. That is, the terminal may independently report the first duration associated with different OCC multiplexing methods.

[0228] For example, for NPUSCH format 1, a specific terminal can independently report the window length of the supported phase continuity maintenance for different OCC schemes (an optional example of the first duration mentioned above).

[0229] Optionally, at least two of the sixth, seventh, eighth, and ninth indication fields can be combined with each other. For example, the first information may simultaneously include both the seventh and eighth indication fields to indicate the window length for phase continuity maintenance under different subcarrier numbers (tone counts) and SCS combinations. For instance, for NPUSCH format 1, a specific terminal can report independent window lengths for phase continuity maintenance for different tone counts and SCS combinations.

[0230] Optionally, in some embodiments, the terminal can report its ability to maintain phase continuity to the network device by sending first information. The terminal's ability to maintain phase continuity may include at least one first duration supported by the terminal, which can also be referred to as the window length reported by the terminal. The interpretation of the reported window length can be illustrated as follows: the candidate value of the reported window length can be {2, 4}, etc. The unit can be milliseconds (ms), subframes, slots, or symbols. That is, the reported window length can be at least one numerical value, and the corresponding duration (or time-domain duration) determined based on this value can be: for different SCSs, the time-domain duration is calculated using a specified SCS. For example, a 15kHz SCS is used for calculation. Or, for different SCSs, independent SCSs are used to calculate their respective time-domain durations. For example, if the terminal reporting window length is 4, and assuming the unit is slot, then for a 3.75kHz SCS NPUSCH format 1 channel, the time-domain duration is 2 slots (equivalent to 4ms in physical time units), and for a 15kHz SCS, the time-domain duration is also 2 slots (equivalent to 1ms in physical time units). Furthermore, the 3.75kHz SCS and 15kHz SCS can use different time units; for example, the 3.75kHz SCS uses a symbol as the time unit, while the 15kHz SCS uses a slot, etc.

[0231] Optionally, in some embodiments, the first duration is greater than or equal to the duration of the time-domain resource mapped by the maximum OCC sequence length of the OCC multiplexing scheme supported by the terminal. That is, the window length of the phase continuity maintenance reported by the terminal (an optional example of the first duration) should not be less than ("should not be less than" that is, greater than or equal to) the duration of the time-domain resource mapped by the maximum OCC length under the OCC scheme supported by the terminal (an optional example of the duration of the aforementioned time-domain resource).

[0232] Optionally, in some embodiments, the duration of the first time window is less than or equal to the first duration. That is, the duration of the maintenance window indicated by the network device (an optional example of the duration of the first time window mentioned above) should not be greater than ("should not be greater than" means: less than or equal to) the duration of the maintenance window reported by the terminal (an optional example of the first duration mentioned above).

[0233] Optionally, in some embodiments, the duration of the first time window is less than or equal to the duration of the time-domain resource mapped by the OCC sequence length of the OCC multiplexing method supported by the terminal.

[0234] Optionally, in some embodiments, the terminal does not expect the length of the phase maintenance window indicated by the base station (an optional example of the duration of the aforementioned first time window) to be greater than the length of the time-domain resources mapped (covered) by the OCC length supported by the terminal. That is, the terminal expects the length of the phase maintenance window indicated by the base station (an optional example of the duration of the aforementioned first time window) to be less than or equal to the length of the time-domain resources mapped (covered) by the OCC length supported by the terminal (or: the duration of the time-domain resources).

[0235] Optionally, in some embodiments, the terminal does not expect the length of the phase maintenance window configured and / or indicated by the base station (an optional example of the duration of the aforementioned first time window) to be greater than the length of the phase maintenance window supported by the terminal (an optional example of the aforementioned first duration). That is, the terminal expects the length of the phase maintenance window configured and / or indicated by the base station (an optional example of the duration of the aforementioned first time window) to be less than or equal to the length of the phase maintenance window supported by the terminal (an optional example of the aforementioned first duration).

[0236] In step S2102, the terminal determines the first time window based on the first information.

[0237] The first time window is the phase-continuous time window for the transmission of the first channel orthogonal coverage code (OCC) multiplexing.

[0238] Optionally, in some embodiments, the first time window can be determined by the terminal and network device based on the first information reported by the terminal, as agreed upon by the protocol. That is, the protocol stipulates that the terminal can determine the first time window based on the first information. Or the protocol stipulates that the network device can determine the first time window based on the first information. For example, the terminal and the base station can simultaneously determine the phase maintenance window (an optional example of the first time window) based on the duration of the maintenance window reported by the terminal (an optional example of the first duration).

[0239] Optionally, in some embodiments, if the network device does not configure a phase maintenance window (an optional example of a first time window) for the terminal, the terminal can determine the phase maintenance window based on the first information by using the methods described below, one and / or two.

[0240] Optionally, in some embodiments, the process of determining the first time window based on the first information can be carried out by determining the first time window based on at least one of the OCC multiplexing method supported by the terminal, the OCC sequence length supported by the terminal, and the first duration. This enables accurate determination of the first time window, supports correct transmission of the first channel using OCC multiplexing, and maintains phase continuity within the first time window when transmitting the first channel based on OCC multiplexing, ensuring that the network device can correctly demultiplex the first channel using OCC and improving communication performance.

[0241] Optionally, in some embodiments, Method 1: The protocol stipulates that the terminal and the base station simultaneously determine the phase maintenance window based on the OCC length reported by the terminal (an optional example of the first time window mentioned above). Specifically, the method for determining the phase maintenance window for different SCSs, different subcarrier intervals, different channels, different OCC schemes, or different OCC lengths is the same as the method described above where the terminal implicitly indicates the phase maintenance window based on the OCC length. In this method, the phase maintenance window determined by the terminal and the phase maintenance window implicitly reported by the terminal for different SCSs and / or different channels and / or different tone numbers are of the same length.

[0242] Optionally, in some embodiments, Method Two: The protocol stipulates that the terminal and the base station simultaneously determine the phase maintenance window (an optional example of the first time window mentioned above) based on the duration of the maintenance window reported by the terminal (an optional example of the first time window mentioned above). For example, for different tone numbers, or different subcarrier spacings, or different channels, or different OCC schemes, or different OCC lengths, the phase maintenance window (an optional example of the first time window mentioned above) can be determined based on the duration of the maintenance window reported by the terminal.

[0243] Optionally, in some other embodiments, step S2102 may be omitted. The network device determines a first time window based on the first information, and the network device can send second information to the terminal. The second information is used to indicate the first time window to the terminal, and the terminal can receive the second information sent by the network device. That is, the network device can determine the maintenance window (an optional example of the first time window) based on the first information reported by the terminal, and configure the maintenance window to the terminal through the second information.

[0244] Optionally, in some other embodiments, if step S2102 is not performed, and the network device determines and / or indicates the first time window to the terminal based on the first information (for example, the first time window can be configured and / or indicated to the terminal through the second information), then the second information may include at least one of the following: third indication information and fourth indication information; wherein, the third indication information is used to indicate that the second time window corresponding to the DMRS bundling function is used as the first time window, the second time window is determined based on a second duration, and the second duration is used for the terminal to maintain phase continuity based on the DMRS bundling function; the fourth indication information is used to indicate the first time window. Thus, a suitable method can be selected to configure and / or indicate the first time window to the terminal, so as to support the terminal in correctly performing OCC multiplexing transmission of the first channel.

[0245] Network devices can configure maintenance windows (an optional example of first-time windows) for terminals in the following way:

[0246] Network devices can indicate a first time window to a terminal by sending a third instruction message.

[0247] For example, the third indication information can be the pusch-TimeDomainWindowLength-r17 parameter. That is, by configuring the pusch-TimeDomainWindowLength-r17 parameter, the phase continuity window (another optional example of the first time window) required for uplink channel OCC multiplexing is indicated to the terminal.

[0248] In this approach, the same parameters can be used to determine the phase continuity window for different OCC schemes; and / or the same parameters can be used to determine the phase continuity window for different channels; and / or the same parameters can be used to determine the phase continuity window for different subcarrier spacings; and / or the same parameters can be used to determine the phase continuity window for different tone numbers; and / or the same parameters can be used to determine the phase continuity window for different OCC lengths. Specifically, the determination of the physical time value under different SCSs can be found in the "Interpretation Method of Window Length Reported by Terminal" in the above embodiment, and there are no restrictions on this.

[0249] It should be noted that in this method, the `pusch-TimeDomainWindowLength-r17` parameter can be reused under information elements (IEs) related to OCCmultiplexing configuration. That is, even if the base station does not configure the `DMRS-Bundling-Config-r17` parameter, it can still indicate the OCCmultiplexing phase maintenance window (another optional example of the first time window) through the `pusch-TimeDomainWindowLength-r17` parameter. Alternatively, the `pusch-TimeDomainWindowLength-r17` parameter is still indicated under `DMRS-Bundling-Config-r17`, but it does not need to be used in conjunction with `PUSCH-DMRS-Bundling-r17`. In other words, even if the base station configures the `pusch-TimeDomainWindowLength-r17` parameter under the `DMRS-Bundling-Config-r17` IE, it is not necessary to enable `pusch-DMRS-Bundling-r17`. Alternatively, when configuring OCC multiplexing for the base station, DMRS bundling must be enabled.

[0250] Optionally, in other embodiments, the network device sends a fourth indication message to the terminal to configure and / or indicate a first time window for the terminal. The fourth indication message may, for example, be a new RRC parameter. For instance, the base station can indicate the phase maintenance window using a newly introduced RRC parameter.

[0251] In step S2103, the network device determines the first time window based on the first information.

[0252] Optionally, in some embodiments, the network device may use the same method as in the terminal described above to determine the first time window based on the first information. If the network device configures and / or indicates the first time window to the terminal, the network device may configure and / or indicate the first time window to the terminal. If the protocol stipulates that the terminal determines the first time window based on the first information, the network device may not send the first time window to the terminal.

[0253] Optionally, in some embodiments, the network device may determine a first time window based on the first information and use the first time window to perform OCC demultiplexing on the received first channel, as described below.

[0254] Step S2104: The terminal sends the first channel to the network device according to the first time window.

[0255] Optionally, in some embodiments, after determining the first time window, the terminal may send the first channel based on the first time window.

[0256] Optionally, in some embodiments, the terminal may perform OCC multiplexing transmission of the first channel and maintain phase continuity of the orthogonal coverage code OCC multiplexing transmission of the first channel within a first time window.

[0257] Optionally, in some embodiments, the network device can receive a first channel and determine that the phase of the first channel's orthogonal coverage code (OCC) multiplexing transmission is continuous within a first time window. Then, the network device can perform OCC demultiplexing on the received first channel based on the first time window, thereby correctly performing OCC demultiplexing on the first channel and improving communication performance.

[0258] This disclosure provides a method for determining a phase maintenance window (an optional example of the first time window mentioned above) to support the receiver in performing OCC demultiplexing based on the assumption that the channels on multiple resources of the same symbol spread are the same or similar, thereby ensuring link transmission performance, realizing system expansion, and supporting more terminals to perform uplink transmission under the premise of limited time and frequency resources and limited terminal transmission power.

[0259] The communication method involved in the embodiments of this disclosure 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, etc., but not limited thereto.

[0260] 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.

[0261] In the embodiments disclosed herein, each step and its optional implementation can also be carried out independently.

[0262] In this embodiment, the terminal sends first information to the network device and can determine a first time window based on the first information. The first time window is a time window for phase continuity during the transmission of the first channel using orthogonal coverage code (OCC). The terminal can send the first channel to the network device based on the first time window, and the network device can determine the first time window based on the first information and receive the first channel using the first time window. Therefore, when transmitting the first channel based on OCC multiplexing, the terminal can maintain the phase continuity of the first channel within the first time window, thereby ensuring that the network device can correctly demultiplex the first channel using OCC and improving communication performance.
