However, when the UE repeatedly transmits data, it occupies a large amount of wireless resources, resulting in a reduction in the amount of data transmitted in the system. When multiple UEs need to transmit data, due to the large occupation of wireless resources, the system cannot meet the resource requirements of all UEs, leading to a decrease in the system capacity.

[0030] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.

[0031] In this article, the character " / " generally indicates an "or" relationship between the associated objects before and after. For example, A / B can be understood as A or B.

[0032] The terms "first" and "second" in the specification and claims of the present disclosure are used to distinguish different objects, rather than to describe a specific order of the objects.

[0033] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the present disclosure are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or modules is not limited to the listed steps or modules, but optionally further includes other steps or modules not listed, or optionally further includes other steps or modules inherent to these processes, methods, products, or devices.

[0034] In addition, in the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present disclosure should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Exactly speaking, using words such as "exemplary" or "for example" is intended to present concepts in a specific manner.

[0035] Currently, UE can use sequence extension schemes to extend transmission resources through different sequences (such as orthogonal cover code (OCC) sequences), so that multiple UEs can use the same wireless resources for uplink transmission at the same time without interfering with each other, thereby improving system capacity. However, when there are multiple sequence extension schemes in the communication system, how the terminal determines the extension scheme to be used becomes a technical problem that needs to be solved urgently.

[0036] For example, Figure 1 As shown in the figure, if UE1 and UE2 repeatedly upload in the same time domain and frequency domain resources, they are extended using the OCC sequence [+1+1; +1 -1]. UE1 selects the sequence [+1+1] and sends a signal X1; UE2 selects the sequence [+1 -1] and sends a signal X2. When the number of repetitions is 2, the first repeated superimposed signal (Y1) is X1H 1.1 +X2H 2.1 The signal (Y2) of the first repeated superposition is X1H 1.2 -X2H 2.2 Among them, H 1.1 and H 1.2 are the system functions of the first and second repetitions of UE1 sending signals (assuming H 1.1 and H 1.2 Same, both are H1), H 2.1 and H 2.2 are the system functions of the first and second repetitions of UE2 sending signals (assuming H 2.1 and H 2.2 The same is H2), then the signal X1 sent by UE1 can be expressed by formula 1, and the signal X2 sent by UE2 can be expressed by formula 2.

[0037] X1=(Y1+Y2) / 2H1 Formula 1.

[0038] X2=(Y1-Y2) / 2H2 Formula 2.

[0039] However, when there are multiple sequence extension schemes in a communication system, how a terminal determines an extension scheme to be used becomes a technical problem that needs to be solved urgently.

[0040] To solve the above problems, embodiments of the present disclosure provide a wireless communication method, which is applied to a first node. The first node can determine a unit of transmission resources. Then, based on the unit of transmission resources, the first node can apply a sequence to the transmission resources for uplink transmission. In this way, the first node can use the sequence to expand the transmission resources, thereby improving the system capacity. Moreover, by determining the unit of transmission resources, the first node can use different sequence expansion schemes based on different units of transmission resources.

[0041] To facilitate the understanding of the embodiments of the present disclosure, first, a communication system shown in Figure 2 will be used as an example to detail the communication system applicable to the embodiments of the present disclosure. Exemplarily, Figure 2 FIG. is a schematic diagram of the architecture of a communication system applicable to the wireless communication method provided by the embodiments of the present disclosure. As Figure 2 shown, the communication system includes a terminal and a network device.

[0042] Among them, the above-mentioned terminal is a terminal that accesses the above-mentioned communication system and has a wireless transceiver function, or a chip or chip system that can be set in the terminal. The terminal can also be referred to as a user device, an access terminal, a user unit, a user station, a mobile station, a mobile device, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The terminal in the embodiments of the present disclosure can be a mobile phone, a tablet computer (Pad), a computer with a wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, an in-vehicle terminal, an RSU with terminal functions, an Internet of Things terminal, etc. The terminal of the present disclosure can also be an in-vehicle module, an in-vehicle module, an in-vehicle component, an in-vehicle chip, or an in-vehicle unit built in a vehicle as one or more components or units. The vehicle can implement the communication method provided by the present disclosure through the built-in in-vehicle module, in-vehicle module, in-vehicle component, in-vehicle chip, or in-vehicle unit.

[0043] The above-mentioned network device is located on the network side of the above-mentioned communication system and is a device with wireless transceiver functions or a chip or chip system that can be disposed in the device. The network device includes, but is not limited to: Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), wireless relay node, wireless backhaul node, transmission and reception point (TRP or transmission point, TP), etc. It can also be a 5G device, such as a gNB in a new radio (NR) system, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or it can also be a network node that constitutes a gNB or a transmission point, such as a baseband unit (BBU), or a distributed unit (DU), a roadside unit (RSU) with base station functions, etc.

[0044] Exemplarily, the above-mentioned communication system can be applied to a new radio (NR) terrestrial network (TN). Among them, the terminal in the communication system can be the first node, and the network device can be the second node.

[0045] In some other embodiments, the communication system may further include: a flying platform. As Figure 3 shown, the communication system may include: a network device, a terminal, and a flying platform.

[0046] Among them, the network device is an access network device set on the ground, and signals can be forwarded through a flying platform between the terminal device and the access network device for communication. Specifically, communication can be carried out between the flying platform and the access network device through a next generation (NG) interface. Among them, the communication link between the flying platform and the access network device can be called a feeder link. The flying platform can provide a transmission / reception point (TRP) for wireless access of the terminal device, and this TRP can transparently transmit data between the terminal device and the access network device, thereby realizing the communication connection between the terminal device and the access network device. At this time, it can be described that the flying platform operates in the transparent mode. It should be noted that the access network device can also be described as a gateway station, a ground station, etc., without limitation.

[0047] In some embodiments, an access network device can be carried on the flying platform. When the access network device is carried on the flying platform, the access network device moves synchronously with the flying platform. The access network device and the flying platform can be regarded as a whole. At this time, the flying platform can be regarded as an access network device, or it can be described that the flying platform operates in the regenerative mode, that is, the flying platform has the functions of an access network device. In addition, the communication link between the flying platform and the terminal device can be called a service link.

[0048] It should be noted that the flying platform can be an aircraft such as a satellite or a drone. Exemplarily, the flying platform can include a geostationary orbit satellite, a non-geostationary orbit satellite, a low-earth orbit satellite, a medium-earth orbit satellite, a geosynchronous orbit satellite, an unmanned flight system platform, or a high-earth orbit satellite, etc., without limitation.

[0049] Alternatively, the access network device can be distributedly carried on the flying platform based on a distributed unit (DU). When the access network device is distributedly carried on the flying platform based on the DU, the flying platform can be regarded as a part of the access network device, or it can be described that the flying platform operates in the regenerative mode, that is, the flying platform has the functions of a part of the access network device.

[0050] Exemplarily, the above communication system can be applied to a NR non-terrestrial network (NTN). Among them, the terminal in this communication system can be the first node, and the network device or the flying platform can be the second node.

[0051] It should be noted that the methods in the following embodiments can all be implemented in the above communication system. The solutions in the embodiments of the present disclosure can also be applied to other communication systems, and the corresponding names can also be replaced with the names of the corresponding functions in other communication systems.

[0052] After introducing the application scenarios and implementation environments of the embodiments of the present disclosure, the wireless communication method provided by the embodiments of the present disclosure will be described in detail below in combination with the above implementation environment.

[0053] As Figure 4 shown, a wireless communication method provided by an embodiment of the present disclosure includes:

[0054] S401. Determine the unit of transmission resources.

[0055] Among them, the unit of transmission resources is the unit granularity when the first node uses sequence-expanded transmission resources. One element in the sequence is applied to one unit of transmission resources.

[0056] In the embodiments of the present disclosure, the unit of transmission resources includes at least one of the following: time-domain resource unit, frequency-domain resource unit.

[0057] Among them, the time-domain resource unit includes at least one of the following: one or more symbols, one or more time slots, the time-domain resources occupied by one transmission repetition, the time-domain resources occupied by one transmission repetition corresponding to one redundancy version RV (Redundancy Version).

[0058] Each time-domain resource unit will be introduced separately below.

[0059] First, when the time-domain resource unit includes one or more symbols, it shows that the unit of transmission resources can be one symbol, or the unit of transmission resources can be composed of multiple symbols. For example, if the unit of transmission resources is composed of 4 symbols, then one element in the sequence is applied to 4 symbols.

[0060] Second, when the time-domain resource unit includes one or more time slots, it shows that the unit of transmission resources can be one time slot, or the unit of transmission resources can be composed of multiple time slots. For example, if the unit of transmission resources is composed of 4 time slots, then one element in the sequence is applied to 4 time slots.

[0061] Third, when the time-domain resource unit includes the time-domain resources occupied by one transmission repetition, it shows that the unit of transmission resources is determined by the time-domain resources occupied by one transmission repetition. For example, if the time-domain resources occupied by one transmission repetition are one time slot, then the unit of transmission resources is one time slot. Another example is that if the time-domain resources occupied by one transmission repetition are four time slots, then the unit of transmission resources is composed of four time slots.

[0062] It should be noted that the time-domain resources repeatedly occupied by one transmission in the embodiments of the present disclosure are not limited. For example, one transmission repetition may occupy one, two, eight time slots, etc.

[0063] Fourth, in the case where the time-domain resource unit includes the time-domain resources occupied by a transmission repetition corresponding to an RV value, it is described that the unit of the transmission resource is determined by the time-domain resources occupied by the transmission repetition corresponding to the RV value. For example, one RV value corresponds to one transmission repetition, and one transmission repetition occupies two time slots, then the unit of the transmission resource consists of two time slots. Another example is that one RV value corresponds to two transmission repetitions, and one transmission repetition occupies two time slots, then the unit of the transmission resource consists of four time slots.

[0064] In the embodiments of the present disclosure, the frequency-domain resource unit includes at least one of the following: one or more resource elements (RE), one or more resource blocks (RB).

[0065] It can be understood that due to different units of the transmission resource, the first node can use different sequence extension schemes. In this way, the frequency offset resistance of the first node can be increased.

[0066] In the embodiments of the present disclosure, the sequence includes at least one of the following: OCC sequence, non-orthogonal multiple access (NOMA) sequence, DFT sequence, Walsh sequence, Zadoff-Chu (ZC) sequence, Hadamard sequence.

[0067] Exemplarily, the Walsh sequence of length 2 may include: [+1 -1], [+1 -1]. Or, the Walsh sequence of length 4 may include: [+1 +1 +1 +1], [+1 -1 +1 -1], etc. Or, the DFT sequence of length 3 may further include: [+1 +1 +1], [+1 e j×2×π×1 / 3 e j×2×π×2 / 3 , [+1 e j×2×π×2 / 3 e j×2×π×1 / 3 , etc. Wherein, e is used to represent a constant, and its value is approximately 2.718281828459045 (an infinite non-recurring decimal). j is used to represent the imaginary unit (the square root of -1).

[0068] S402. Based on the unit of the transmission resource, apply the sequence to the transmission resource for uplink transmission.

[0069] It should be noted that in the embodiments of the present disclosure, applying a sequence to transmission resources can be referred to as a sequence expansion scheme. Different units of transmission resources correspond to different sequence expansion schemes. The processes of using different sequence expansion schemes are introduced below.

[0070] In one possible implementation, the unit of transmission resources is one or more symbols, and the sequence expansion scheme is a symbol-level sequence expansion scheme. For each element in the sequence, the element can be applied to one or more symbols for uplink transmission.

[0071] Exemplarily, taking the unit of transmission resources as one symbol as an example. Suppose UE1 and UE2 perform transmission in the same time-domain and frequency-domain resources. UE1 uses the sequence [S1.1, S1.2, S1.3, S1.4], and UE2 uses the sequence [S2.1, S2.2, S2.3, S2.4]. As Figure 5 shown, each symbol is repeated four times and continuously mapped to 4 time-domain symbols. One symbol is multiplied by one element in the sequence. For example, symbol 1 is multiplied by S1.1.

[0072] Taking the unit of transmission resources as two symbols as an example. Suppose UE1 and UE2 perform transmission in the same time-domain and frequency-domain resources. UE1 uses the sequence [S1.1, S1.2, S1.3, S1.4], and UE2 uses the sequence [S2.1, S2.2, S2.3, S2.4]. As Figure 6 shown, every two symbols are repeated four times and continuously mapped to 8 time-domain symbols. Two symbols are multiplied by one element in the sequence. For example, symbol 1 and symbol 2 are multiplied by S1.1.

[0073] In another possible implementation, the unit of transmission resources is one or more time slots, and the sequence expansion scheme is a time-slot-level sequence expansion scheme. For each element in the sequence, the element can be applied to one or more time slots for uplink transmission.

[0074] Exemplarily, taking the unit of transmission resources as one time slot as an example. Suppose UE1 and UE2 perform repeated uploads in the same time-domain and frequency-domain resources. UE1 uses the sequence [S1.1, S1.2, S1.3, S1.4], and UE2 uses the sequence [S2.1, S2.2, S2.3, S2.4]. As Figure 7 shown, the data of each time slot is repeated four times and continuously mapped to 4 time slots. One time slot is multiplied by one element in the sequence. For example, S1.1 is multiplied by time slot 1.

[0075] Take the unit of transmission resource as two time slots as an example. Suppose UE1 and UE2 perform repeated uplinks in the same time-domain and frequency-domain resources. UE1 uses the sequence [S1.1, S1.2, S1.3, S1.4], and UE2 uses the sequence [S2.1, S2.2, S2.3, S2.4]. As Figure 8 shown, the data of every two time slots is repeatedly mapped to 8 time slots continuously four times, and two time slots are multiplied by one element in the sequence. For example, time slot 1 and time slot 2 are multiplied by S1.1.

[0076] In another possible implementation, the unit of transmission resource is the time-domain resource occupied by one transmission repetition, and the sequence extension scheme is the repetition-level sequence extension scheme. For each element in the sequence, this element can be applied to the time-domain resource occupied by one transmission repetition for uplink transmission.

[0077] Exemplarily, take the time-domain resource occupied by one transmission repetition as two time slots as an example. The unit of transmission resource is two time slots. Suppose UE1 and UE2 perform repeated uplinks in the same time-domain and frequency-domain resources. UE1 uses the sequence [S1.1, S1.2, S1.3, S1.4], and UE2 uses the sequence [S2.1, S2.2, S2.3, S2.4]. As Figure 9 shown, the data of every two time slots is repeatedly mapped to 8 time slots continuously four times, and two time slots are multiplied by one element in the sequence. For example, time slot 1 and time slot 2 are multiplied by S1.1.

[0078] In some embodiments, one or more sequences are applied to all units of the transmission resource.

[0079] Exemplarily, all units of the transmission resource include 8 time slots, and the length of the sequence is 4. Then two sequences can be used for the 8 time slots, and one element in the sequence is multiplied by one time slot.

[0080] In another possible implementation, the unit of transmission resource is the time-domain resource occupied by one transmission repetition corresponding to a redundancy version (RV) value, and the sequence extension scheme is the RV-level sequence extension scheme. For each element in the sequence, this element can be applied to the time-domain resource occupied by one transmission repetition corresponding to a redundancy version (RV) value for uplink transmission.

[0081] Exemplarily, suppose the RV is [0, 2, 0, 2], and one RV value is applied to one transmission repetition. Then two transmission repetitions are multiplied by one element in the sequence. Suppose UE1 and UE2 perform 8 uplink repetitions in the same time-domain and frequency-domain resources. UE1 uses the sequence [S1.1, S1.2, S1.3, S1.4], and UE2 uses the sequence [S2.1, S2.2, S2.3, S2.4]. As Figure 10As shown, 8 upload repetitions occupy 16 time slots, so every two repetitions (4 time slots) are multiplied by one element in the sequence. For example, time slots 1, 2, 3, and 4 are multiplied by S1.1.

[0082] For another example, if RV is [0, 3, 2, 1] and one RV value is applied to one transmission repetition, then four transmission repetitions are multiplied by one element in the sequence.

[0083] In another possible implementation, the unit of transmission resource is a frequency-domain resource unit, and the sequence expansion scheme is a frequency-domain level sequence expansion scheme. For each element in the sequence, this element can be applied to a frequency-domain resource unit for uplink transmission.

[0084] In an exemplary case, the frequency-domain level sequence expansion scheme can be an in-symbol pre-DFT sequence expansion scheme. The pre-DFT sequence expansion scheme can be used after modulation is performed in the modulation module and before discrete Fourier transform is performed in the DFT module. Taking a frequency-domain resource of N subcarriers and a sequence length of M as an example. First, the modulated symbols are mapped to N / M subcarriers, then M-fold frequency-domain spreading (i.e., repetition on the frequency-domain resource) is performed to fill all N subcarriers, and finally, each N / M subcarriers are multiplied by one element in the sequence.

[0085] Exemplarily, as Figure 11 shown, if UE1 and UE2 are each allocated 12 subcarriers, UE1 uses the sequence [S1.1, S1.2], and UE2 uses the sequence [S2.1, S2.2]. The modulated symbols can be mapped to 6 subcarriers, then spread 2-fold to all 12 subcarriers, and finally, each 6 subcarriers are multiplied by one element in the sequence. For example, subcarriers x0 - x5 are multiplied by S1.1.

[0086] In the embodiments of the present disclosure, the uplink transmission includes at least one of the following: multiple repetitions of the transmission of the Physical Uplink Shared Channel (PUSCH) scheduled by DCI; multiple repetitions of the transmission of the Physical Uplink Shared Channel (PUSCH) scheduled by at least one of the Random Access Response (RAR) message or the fallback RAR message; multiple repetitions of the PUSCH transmission in the random access process; multiple repetitions of the PUSCH transmission with configured grant; multiple repetitions of the PUSCH transmission in the Pre-configured Uplink Resources (PUR); multiple repetitions of the PUSCH transmission in the Early Data Transmission (EDT).

[0087] Exemplarily, multiple repetitions of the PUSCH transmission scheduled by the RAR message may schedule msg3 in the 4-step Random Access Channel (RACH) procedure for RAR (msg2). As another example, multiple repetitions of the PUSCH transmission scheduled by the fallback RAR message may schedule msg3 in the 2-step RACH procedure for the fallback RAR (msgB).

[0088] In some embodiments, the Physical Uplink Shared Channel may include at least one of the following: Narrow Band Internet of Things Physical Uplink Shared Channel (NPUSCH), Enhanced Mobile Broadband Physical Uplink Shared Channel (eMBB PUSCH), Ultra-Reliable and Low-Latency Communications Physical Uplink Shared Channel (uRLLC PUSCH), Massive Machine Type Communications Physical Uplink Shared Channel (mMTC PUSCH).

[0089] In some embodiments, the uplink transmission may further include at least one of the following: Physical Uplink Control Channel (PUCCH), Narrow Band Internet of Things Physical Uplink Control Channel (NPUCCH), Narrow Band Internet of Things Physical Random Access Channel (NPRACH).

[0090] It should be noted that the uplink transmission may be applied to NTN networks, TN networks, and Narrow Band Internet of Things (NB-IoT), and the embodiments of the present disclosure do not limit this.

[0091] In some embodiments, the second node may receive an uplink transmission sent by the first node. The uplink transmission is a transmission that applies a sequence to a transmission resource based on a unit of the transmission resource.

[0092] Based on the above technical solution, the first node may use a sequence to expand the transmission resource, thereby improving the system capacity. Moreover, by determining the unit of the transmission resource, the first node can use different sequence expansion schemes based on different units of the transmission resource.

[0093] The above is an introduction to the process of the first node applying a sequence to the transmission resource for uplink transmission by determining the unit of the transmission resource. Next, the process of the first node determining the unit of the transmission resource will be specifically introduced.

[0094] In the embodiments of the present disclosure, the first node may determine the unit of the transmission resource according to unit indication information, where the unit indication information is used to indicate the unit of the transmission resource. The unit indication information may be information obtained from the second node.

[0095] In a possible implementation manner, the second node may send the unit indication information to the first node, and the first node receives the unit indication information sent by the second node.

[0096] The unit indication information is carried in any one of the following signaling: System Information (SI), Radio Resource Control (RRC) message, MAC Control Element (MAC CE), Downlink Control Information (DCI).

[0097] Exemplarily, the SI may be System Information Block (SIB) 1. Alternatively, the SI may be the narrowband Internet of Things system information block SIB TypeX-NB, where X takes an integer value between [1, 32].

[0098] In some embodiments, when the unit indication information is carried in the RRC message, the unit indication information is located in at least one of the following levels of information elements: cell-level information elements, UE-level information elements, Bandwidth Part (BWP)-level information elements, signal or channel-level information elements, transmission-level information elements.

[0099] It should be noted that the cell-level information elements (IEs) (or UE basic information elements) are used to indicate that the transmissions of UEs in the cell can all use the unit indication information. The BWP-level information elements refer to that any transmission of the UE in this BWP can use the unit indication information. The signal or channel-level information elements refer to that a certain signal or channel transmission of the UE can use the unit indication information. The transmission-level information elements refer to that a specific transmission can use the unit indication information.

[0100] It should be noted that in the case where the parameter is in the transmission-level information element, the unit indication information can be carried as a list in the information element. When scheduling a transmission with DCI, an index in the RRC list is indicated in the field of the DCI as the unit indication information for this transmission.

[0101] Exemplarily, the cell-level information elements (or UE-level information elements) may include at least one of the following: ServingCellConfig, ServingCellConfigCommon, ServingCellConfigCommonSIB, etc. The BWP-level information elements may include at least one of the following: BWP-Uplink, BWP-UplinkCommon, BWP-UplinkDedicated, etc. The signal or channel-level information elements may include at least one of the following: PUSCH-Config, PUSCH-ConfigCommon, PUSCH-ServingCellConfig, PUCCH-Config, PUCCH-ConfigCommon, ConfiguredGrantConfig, RACH-ConfigCommon-NB, NPUSCH-Config-NB, NPRACH-ConfigSIB-NB, PUR-Config-NB, etc.

[0102] It should be noted that for a specific transmission or periodic transmission, the unit indication information can be used as a parameter in the MAC CE. For a transmission scheduled by a specific DCI, the unit indication information can be used as a field of the DCI.

[0103] In some embodiments, the first node may send the capability information of the first node to the second node. The second node may determine the unit of the transmission resource according to the capability information. The capability information of the first node is used to indicate support for uplink transmission based on the unit of the transmission resource. The capability information includes at least one of the following: supported unit of the transmission resource, supported sequence length, supported duration, supported Modulation and Coding Scheme (MCS) index.

[0104] Among them, the supported sequence length is the maximum sequence length supported for use by the first node, and / or, the supported sequence length is the maximum sequence length of the first node using the unit of the transmission resource. The supported duration is the maximum duration of the sequence applied by the first node, and / or, the supported duration is the maximum duration of the first node applying the sequence to the unit of the transmission resource. The supported MCS index is the maximum MCS index supported for use by the first node, and / or, the supported MCS index is the maximum MCS index supported for use by the first node applying the sequence to the unit of the transmission resource.

[0105] It should be noted that when the supported sequence length is the maximum sequence length of the first node using the unit of the transmission resource, it refers to the supported sequence extension scheme. When the supported duration is the maximum duration of the first node applying the sequence to the unit of the transmission resource, it refers to the supported sequence extension scheme. When the supported MCS index is the maximum MCS index supported for use by the first node applying the sequence to the unit of the transmission resource, it refers to the supported sequence extension scheme.

[0106] In some embodiments, the capability information may further include at least one of the following: configuration parameters, specific parameters.

[0107] Exemplarily, for example, when the first node sends that the supported unit of the transmission resource is a time slot, the unit of the transmission resource is a time slot. For another example, the capability information sent by the first node includes: the supported unit of the transmission resource is a time slot, the supported sequence length is 4, and the supported MCS index is 1, then the unit of the transmission resource indicated by the unit indication information satisfies the above conditions.

[0108] In some embodiments, the capability information may include one or more sets of capability information.

[0109] For example, the UE reports two sets of capability information. The first set includes: unit a of the transmission resource, duration a, and index a of MCS. The second set includes: unit b of the transmission resource, duration b, and index b of MCS. Then, in the case of duration a and index a of MCS, the UE may execute the sequence extension scheme based on unit a of the transmission resource. In the case of duration b and index b of MCS, the UE may execute the sequence extension scheme based on unit b of the transmission resource.

[0110] It should be noted that for the specific introduction of the unit process of determining the transmission resource according to the ability information for the second node, reference can be made to the introduction of the unit for determining the transmission resource according to the configuration parameters in the following embodiments, which will not be elaborated here.

[0111] In the embodiments of the present disclosure, the unit indication information includes at least one of the following: specific parameters of the unit of the transmission resource, the unit identifier of the transmission resource, and the configuration parameters.

[0112] The processes of the first node determining the unit of the transmission resource according to the specific parameters of the unit of the transmission resource, the unit identifier of the transmission resource, and the configuration parameters are introduced below. First, the process of determining the unit of the transmission resource according to the specific parameters of the unit of the transmission resource is introduced below.

[0113] In the implementation of the present disclosure, the specific parameters include at least one of the following: symbol-level unit parameters, time-slot-level unit parameters, and frequency-domain-level unit parameters.

[0114] In a possible implementation manner, when the specific parameter is the symbol-level unit parameter, the unit of the transmission resource is one or more symbols. That is to say, the sequence extension scheme used is the symbol-level sequence extension scheme.

[0115] When the specific parameter is the time-slot-level unit parameter, the unit of the transmission resource is one or more time slots. That is to say, the sequence extension scheme used is the time-slot-level sequence extension scheme.

[0116] When the specific parameter is the frequency-domain-level unit parameter, the unit of the transmission resource is a frequency-domain unit. That is to say, the sequence extension scheme used is the frequency-domain-level sequence extension scheme. Among them, the frequency-domain unit can include at least one of the following: one or more resource elements (REs); or, one or more resource blocks (RBs).

[0117] In some embodiments, the specific parameters may further include: RV-level unit parameters.

[0118] In some embodiments, the specific parameter may further be a resource mapping parameter, and the resource mapping parameter is the value of the symbol-level unit parameter or the value of the time-slot-level unit parameter.

[0119] Exemplarily, if the value of the symbol-level unit parameter is 5, it means that every 5 symbols are multiplied by one element in the sequence.

[0120] In some embodiments, the specific parameters may further include a spreading identifier.

[0121] In some embodiments, when the unit indication information includes specific parameters of a unit of transmission resources, the unit indication information may further include at least one configuration parameter.

[0122] It can be understood that through the specific parameters of the unit of transmission resources, the first node can select the corresponding unit of transmission resources for uplink transmission.

[0123] After introducing the process of determining the unit of transmission resources according to the specific parameters of the unit of transmission resources, the process of determining the unit of transmission resources according to the unit identifier of the transmission resources will be introduced below.

[0124] In a possible implementation manner, the unit of transmission resources can be determined according to the unit identifier of the transmission resources.

[0125] Exemplarily, if the unit identifier of the transmission resources is slot, the unit of transmission resources is one or more time slots. If the unit identifier of the transmission resources is symbol, the unit of transmission resources is one or more symbols.

[0126] In some embodiments, when the unit indication information includes the unit identifier of the transmission resources, the unit indication information may further include at least one configuration parameter.

[0127] The process of determining the unit of transmission resources according to the configuration parameter will be introduced below. It should be noted that when applying a sequence to transmission resources, it is required to maintain the consistency of the channel within a certain time. Otherwise, the superimposed signals of multiple UEs will be inaccurate when combined, and the interference of other users cannot be eliminated. Moreover, the frequency offset generated by the crystal oscillators at the transceiver ends will cause the phase to deviate more and more with time.

[0128] In the embodiments of the present disclosure, the first node can determine the unit of transmission resources according to the configuration parameter. Wherein, the configuration parameter includes at least one of the following: sequence length, MCS index, number of users multiplexing resources, RV, transport block size (TBS), priority of the unit of transmission resources.

[0129] It should be noted that the priority of the unit of transmission resources can be represented by specific numerical values. For example, as shown in Table 1, the priority of one or more symbols is 1, the priority of one or more time slots is 2, and the time domain resources occupied by one transmission repetition is 3. Among them, the priority of one or more symbols is higher than that of one or more time slots, and the priority of one or more time slots is higher than that of the time domain resources occupied by one transmission repetition. Alternatively, the priority of the unit of transmission resources can be represented by a priority identifier. For example, if one or more symbols have a priority identifier (such as 0, priority, etc.) and one or more time slots do not have a priority identifier, then the priority of one or more symbols is higher than that of one or more time slots. The embodiments of the present disclosure do not limit this.

[0132] In a possible implementation manner, the first node determines the unit of transmission resources according to the sequence length, which may include at least the following four methods: Method 1.1, Method 1.2, Method 1.3, and Method 1.4.

[0133] Method 1.1, when the sequence length is greater than the length threshold, the unit of transmission resources is the first unit. And / or, when the sequence length is less than the length threshold, the unit of transmission resources is the second unit. And / or, when the sequence length is equal to the length threshold, the unit of transmission resources is the first unit or the second unit. Among them, the time length of the first unit is less than that of the second unit.

[0134] Exemplarily, if the length threshold is 4 and the sequence length is 2, it is determined that the unit of transmission resources is one time slot. If the sequence length is 5, it is determined that the unit of transmission resources is 1 symbol.

[0135] Method 1.2, when the sequence length is greater than the first length threshold, the unit of transmission resources is the first unit. And / or, when the sequence length is less than or equal to the first length threshold and greater than the second length threshold, the unit of transmission resources is the second unit. And / or, when the sequence length is less than the second length threshold, the unit of transmission resources is the third unit. Among them, the first length threshold is greater than the second length threshold. Among them, the time length of the first unit is less than that of the second unit, and the time length of the second unit is less than that of the third unit.

[0136] Exemplarily, suppose the first length threshold is 4 and the second length threshold is 2. When the sequence length is greater than 4, the unit of the transmission resource is a frequency-domain resource unit. When the sequence length is less than or equal to 4 and greater than 2, the unit of the transmission resource is one or more symbols. When the sequence length is less than or equal to 2, the unit of the transmission resource is one or more time slots.

[0137] It should be noted that the embodiments of the present disclosure do not limit the setting methods of the length threshold, the first length threshold, and the second length threshold. For example, the length threshold can be a predefined value (such as encoded in a device, component, or chip). For another example, the length threshold can be the maximum sequence length supported by the first node. For still another example, the length threshold can be a value configured by the second node.

[0138] In some embodiments, at least one of the length threshold, the first length threshold, and the second length threshold can be included in the configuration parameters.

[0139] For example, the configuration parameters include: sequence length {sequence length 1, length threshold}.

[0140] In other embodiments, at least one of the length threshold, the first length threshold, and the second length threshold is not included in the configuration parameters and is carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0141] Mode 1.3, when the sequence length is the first length, the unit of the transmission resource is the first unit. And / or when the sequence length is the second length, the unit of the transmission resource is the second unit. Wherein, the first length is greater than the second length, and the time length of the first unit is less than the time length of the second unit.

[0142] Exemplarily, suppose the value of the sequence length is 2 or 4. When the value of the sequence length is 2, the unit of the transmission resource is one or more time slots. When the value of the sequence length is 4, the unit of the transmission resource is one or more symbols.

[0143] In some embodiments, at least one of the first length and the second length can be included in the configuration parameters.

[0144] For example, the configuration parameters include: sequence length {sequence length 1, the first length, and the second length}.

[0145] In other embodiments, the first length and the second length are not included in the configuration parameters and are carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0146] It can be understood that the sequence length determines the sequence to be used within a period of time. When the sequence length is relatively large, a unit with a smaller time length can be selected to improve the anti-frequency-offset performance.

[0147] In Method 1.4, when the sequence length is greater than the length threshold, the unit of transmission resource is the first group of units, and the first group of units includes at least one unit of transmission resource. And / or, when the sequence length is less than the length threshold, the unit of transmission resource is the second group of units, and the second group of units includes at least one unit of transmission resource. And / or, when the sequence length is equal to the length threshold, the unit of transmission resource is the first group of units or the second group of units. Then, the unit of transmission resource can be determined from the first group of units or the second group of units through the unit group information. The unit group information can be carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0148] Exemplarily, the first group of units includes {the first unit, the second unit}, and the second group of units includes {the second unit, the third unit}. If it is determined that the unit of transmission resource is the first group of units, and the unit group information is used to indicate selecting the first unit in a group of units (for example, the unit group information is 0), then the unit of transmission resource is determined to be the first unit.

[0149] Alternatively, the unit group information includes at least one of the following: Time Domain Resource Assignment (TDRA), Frequency Domain Resource Allocation (FDRA). For example, if the TDRA indicates configuring 10 time slots, then the unit of transmission resource is one or more time slots; if the TDRA indicates configuring 8 symbols, then the unit of transmission resource is one or more symbols.

[0150] It should be noted that TDRA can include at least one of the following parameters: start time, time offset, and time length. FDRA can include at least one of the following parameters: start frequency domain position, number of RBs, number of REs.

[0151] In another possible implementation, the first node determines the unit of transmission resource according to the MCS index. Determining the unit of transmission resource according to the MCS index can include the following six methods: Method 2.1, Method 2.2, Method 2.3, Method 2.4, Method 2.5, and Method 2.6.

[0152] In Method 2.1, when the MCS index is greater than the MCS index threshold, the unit of transmission resource is the first unit. And / or, when the MCS index is less than the MCS index threshold, the unit of transmission resource is the second unit. And / or, when the MCS index is equal to the MCS index threshold, the unit of transmission resource is the first unit or the second unit. Among them, the time length of the first unit is less than the time length of the second unit.

[0153] Method 2.2: When the MCS index is greater than the first MCS index threshold, the unit of the transmission resource is the first unit. And / or when the MCS index is less than or equal to the first MCS index threshold and greater than the second MCS index threshold, the unit of the transmission resource is the second unit. And / or when the MCS index is less than or equal to the second MCS index threshold, the unit of the transmission resource is the third unit. Wherein, the first MCS index threshold is greater than the second MCS index threshold; the time length of the first unit is less than that of the second unit, and the time length of the second unit is less than that of the third unit.

[0154] In some embodiments, when the MCS index is greater than the first MCS index threshold, no sequence is used for uplink transmission. And / or when the MCS index is less than or equal to the first MCS index threshold and greater than the second MCS index threshold, the unit of the transmission resource is the first unit. And / or when the MCS index is less than or equal to the second MCS index threshold, the unit of the transmission resource is the second unit. Wherein, the first MCS index threshold is greater than the second MCS index threshold; the time length of the first unit is less than that of the second unit.

[0155] It should be noted that the embodiments of the present disclosure do not limit the setting methods of the above MCS index threshold, first MCS index threshold, and second MCS index threshold. For example, the MCS index threshold can be a predefined value. For another example, the MCS index threshold can be the MCS index supported by the first node. For another example, the MCS index threshold can be the value configured by the second node.

[0156] In some embodiments, at least one of the MCS index threshold, first MCS index threshold, and second MCS index threshold can be included in the configuration parameters.

[0157] For example, the configuration parameters can include: MCS index {MCS index 1, MCS index threshold}.

[0158] In some embodiments, at least one of the MCS index threshold, first MCS index threshold, and second MCS index threshold is not included in the configuration parameters and is carried in any one of the following signaling: SI, RRC message, MAC CE, DCI.

[0159] Method 2.3: When the MCS index is the first MCS index, the unit of the transmission resource is the first unit. And / or when the MCS index is the second MCS index, the unit of the transmission resource is the second unit. Wherein, the first MCS index is greater than the second MCS index, and the time length of the first unit is less than that of the second unit.

[0160] In some embodiments, at least one of the first MCS index and the second MCS index may be included in the configuration parameters.

[0161] For example, the configuration parameters include: MCS index {MCS index 1, the first MCS index, and the second MCS index}.

[0162] In other embodiments, the first MCS index and the second MCS index are not included in the configuration parameters and are carried in any one of the following signaling: SI, RRC message, MAC CE, DCI.

[0163] Method 2.4, MCS and sequence length are parameters affecting the anti-frequency offset performance of uplink transmission in two different dimensions, and the unit of transmission resource can be determined by the MCS index and the sequence length.

[0164] In an exemplary case, when the MCS index is greater than the MCS index threshold and the sequence length is greater than the length threshold, the unit of transmission resource is the first unit. And / or, when the MCS index is less than or equal to the MCS index threshold and / or the sequence length is less than or equal to the length threshold, the unit of transmission resource is the second unit.

[0165] In another exemplary case, when the MCS index is greater than the MCS index threshold and the sequence length is greater than the length threshold, the sequence is not used. And / or, when the MCS index is less than or equal to the MCS index threshold or the sequence length is less than or equal to the length threshold, the unit of transmission resource is the first unit. And / or, when the MCS index is less than or equal to the MCS index threshold and the sequence length is less than or equal to the length threshold, the unit of transmission resource is the second unit.

[0166] It can be understood that the MCS index can determine the coding rate of channel coding, and the higher the coding rate, the greater the influence of the signal by frequency offset. Therefore, when the MCS index is large, a unit with a smaller time length can be selected to improve the anti-frequency offset performance.

[0167] Method 2.5, when the MCS index is greater than the MCS index threshold, the unit of transmission resource is the first group of units, and the first group of units includes at least one unit of transmission resource. And / or, when the MCS index is less than the MCS index threshold, the unit of transmission resource is the second group of units, and the second group of units includes at least one unit of transmission resource. And / or, when the MCS index is equal to the MCS index threshold, the unit of transmission resource is the first group of units or the second group of units. Then, the unit of transmission resource can be determined from the first group of units or the second group of units through the unit group information. The unit group information can be carried in any one of the following signaling: SI, RRC message, MAC CE, DCI.

[0168] Exemplarily, the first set of units includes {the first unit, the second unit}, and the second set of units includes {the second unit, the third unit}. If it is determined that the unit for transmitting resources is the first set of units, and the unit group information is used to indicate the selection of the first unit in a set of units (for example, the unit group information is 0), then the unit for transmitting resources is determined to be the first unit.

[0169] In Method 2.6, when the MCS index is greater than the MCS index threshold, the unit for transmitting resources is the first unit, and the sequence length is the first sequence length group. And / or, when the MCS index is less than the MCS index threshold, the unit for transmitting resources is the second unit, and the sequence length is the second sequence length group. And / or, when the MCS index is equal to the MCS index threshold, the unit for transmitting resources is the first unit or the second unit. Among them, the time length of the first unit is less than the time length of the second unit. Then, the sequence length can be determined from the first sequence length group or the second sequence length group through the sequence group information. The sequence group information can be carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0170] Exemplarily, the first sequence length group includes {sequence length 1, sequence length 2}, and the second sequence length group includes {sequence length 2, sequence length 3}. If it is determined that the unit for transmitting resources is the second unit, the sequence length is the second sequence length group, and the sequence group information is used to indicate the selection of the first sequence length in a set of sequence lengths (for example, the sequence group information is 0), then the sequence length is determined to be sequence length 2.

[0171] Alternatively, the sequence group information includes at least one of the following: TDRA, FDRA. For example, the sequence length group is {sequence length 2, sequence length 3}, and if the time domain resource allocation parameter indicates the configuration of 8 time slots, then the sequence length is determined to be sequence length 3; if the time domain resource allocation parameter indicates the configuration of 4 time slots, then the sequence length is determined to be sequence length 2, where sequence length 2 is less than sequence length 3.

[0172] It should be noted that TDRA can include at least one of the following parameters: start time, time offset, and time length. FDRA can include at least one of the following parameters: start frequency domain position, number of RBs, number of REs.

[0173] In another possible implementation, the first node determines the unit for transmitting resources according to the number of users multiplexing resources. Determining the unit for transmitting resources according to the number of users multiplexing resources can include the following three methods: Method 3.1, Method 3.2, Method 3.3.

[0174] Method 3.1: When the number of users multiplexing resources is greater than the user number threshold, the unit for transmitting resources is the first unit. And / or, when the number of users multiplexing resources is less than the user number threshold, the unit for transmitting resources is the second unit. And / or, when the number of users multiplexing resources is equal to the user number threshold, the unit for transmitting resources is the first unit or the second unit. Among them, the time length of the first unit is less than that of the second unit.

[0175] Exemplarily, assuming the user number threshold is 2, when the number of users multiplexing resources is greater than 2, the unit for transmitting resources is one or more symbols. When the number of users multiplexing resources is less than or equal to 2, the unit for transmitting resources is one or more time slots. Or, when the number of users multiplexing resources is greater than 2, the unit for transmitting resources is one or more time slots. When the number of users multiplexing resources is less than or equal to 2, the unit for transmitting resources is one transmission repetition.

[0176] Method 3.2: When the number of users multiplexing resources is greater than the first user number threshold, the unit for transmitting resources is the first unit. And / or, when the number of users multiplexing resources is less than or equal to the first user number threshold and greater than the second user number threshold, the unit for transmitting resources is the second unit. And / or, when the number of users multiplexing resources is less than or equal to the second user number threshold, the unit for transmitting resources is the third unit. Among them, the first user number threshold is greater than the second user number threshold, the time length of the first unit is less than that of the second unit, and the time length of the second unit is less than that of the third unit.

[0177] Exemplarily, assuming the first user number threshold is 4 and the second user number threshold is 2. When the number of users multiplexing resources is greater than 4, the unit for transmitting resources is a frequency domain unit. When the number of users multiplexing resources is less than or equal to 4 and greater than 2, the unit for transmitting resources is one or more symbols. When the number of users multiplexing resources is less than or equal to 2, the unit for transmitting resources is one or more time slots.

[0178] It should be noted that the embodiments of the present disclosure do not limit the setting methods of the user number threshold, the first user number threshold, and the second user number threshold. For example, the user number threshold can be a predefined value (such as encoded in a device, a device, or a chip). For another example, the user number threshold can be the maximum number of users supported by the first node. For another example, the user number threshold can be a value configured by the second node.

[0179] In some embodiments, at least one of the user number threshold, the first user number threshold, and the second user number threshold can be included in the configuration parameters.

[0180] For example, the configuration parameters include: the number of users {the number of users 1, the user number threshold}.

[0181] In some other embodiments, at least one of the user number threshold, the first user number threshold, and the second user number threshold is not included in the configuration parameters and is carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0182] In Mode 3.3, when the number of users multiplexing resources is the first user number, the unit of the transmission resource is the first unit. And / or when the number of users multiplexing resources is the second user number, the unit of the transmission resource is the second unit. Wherein, the first user number is greater than the second user number, and the time length of the first unit is less than the time length of the second unit.

[0183] Exemplarily, suppose the value of the sequence length is 2 or 4. When the sequence length takes the value of 2, the unit of the transmission resource is one or more time slots. When the sequence length takes the value of 4, the unit of the transmission resource is one or more time symbols.

[0184] In some embodiments, at least one of the first user number and the second user number may be included in the configuration parameters.

[0185] For example, the configuration parameters include: the number of users {the number of users 1, the first user number, and the second user number}.

[0186] In some other embodiments, the first user number and the second user number are not included in the configuration parameters and are carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0187] It can be understood that the larger the number of users multiplexing resources, the larger the required sequence length. Therefore, when the number of users multiplexing resources is large, a unit with a smaller time length can be selected to improve the anti-frequency offset performance.

[0188] In another possible implementation, the first node may determine the unit of the transmission resource according to the priority of the unit of the transmission resource.

[0189] Exemplarily, suppose the unit of the transmission resource includes: the first unit and the second unit. If the priority of the first unit is higher than that of the second unit, the unit of the transmission resource is the first unit. Or, suppose when the sequence length is 4, the UE can only use the second unit, then even if the first unit has a priority identifier (or the priority of the first unit is higher than that of the second unit), the unit of the transmission resource is the second unit.

[0190] It should be noted that the present disclosure embodiments do not limit the setting method of the priority of the transmission resource unit. For example, the priority of the transmission resource unit can be a predefined value (such as encoded in a device, component, or chip). For another example, the priority of the transmission resource unit can be the priority supported by the first node. For still another example, the priority of the transmission resource unit can be the value configured by the second node.

[0191] In some embodiments, the priority of the transmission resource unit can be included in the configuration parameters.

[0192] For example, the configuration parameters include: sequence length 1, and the priority of the transmission resource unit.

[0193] In other embodiments, the priority of the transmission resource unit is not included in the configuration parameters and is carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0194] In another possible implementation, the first node can determine the transmission resource unit according to the TBS. Determining the transmission resource unit according to the TBS can include the following four methods: Method 4.1, Method 4.2, Method 4.3, Method 4.4.

[0195] Method 4.1, when the TBS is greater than the TBS threshold, the transmission resource unit is the first unit. And / or, when the TBS is less than the TBS threshold, the transmission resource unit is the second unit. And / or, when the TBS is equal to the TBS threshold, the transmission resource unit is the first unit or the second unit. Among them, the time length of the first unit is less than the time length of the second unit.

[0196] Method 4.2, when the TBS is greater than the first TBS threshold, the transmission resource unit is the first unit. And / or, when the TBS is less than or equal to the first TBS threshold and greater than the second TBS threshold, the transmission resource unit is the second unit. And / or, when the TBS is less than or equal to the second TBS threshold, the transmission resource unit is the third unit. Among them, the first TBS threshold is greater than the second TBS threshold, the time length of the first unit is less than the time length of the second unit, and the time length of the second unit is less than the time length of the third unit.

[0197] In some embodiments, when the TBS is greater than the first TBS threshold, the sequence is not used. And / or, when the TBS is less than or equal to the first TBS threshold and greater than the second TBS threshold, the transmission resource unit is the first unit. And / or, when the TBS is less than or equal to the second TBS threshold, the transmission resource unit is the second unit.

[0198] It should be noted that the present disclosure embodiments do not limit the setting methods of the above TBS threshold, first TBS threshold, and second TBS threshold. For example, the TBS threshold can be a predefined value (such as encoded in a device, component, or chip). For another example, the TBS threshold can be the TBS supported by the first node. For yet another example, the TBS threshold can be the value configured by the second node.

[0199] In some embodiments, at least one of the TBS threshold, first TBS threshold, and second TBS threshold can be included in the configuration parameters.

[0200] For example, the configuration parameters include: TBS{TBS1, TBS threshold}.

[0201] In other embodiments, at least one of the TBS threshold, first TBS threshold, and second TBS threshold is not included in the configuration parameters and is carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0202] Mode 4.3, when the TBS is the first TBS, the unit of the transmission resource is the first unit. And / or, when the TBS is the second TBS, the unit of the transmission resource is the second unit. Wherein, the first TBS is greater than the second TBS, and the time length of the first unit is less than the time length of the second unit.

[0203] In some embodiments, at least one of the first TBS and the second TBS can be included in the configuration parameters.

[0204] For example, the configuration parameters include: TBS{TBS1, first TBS, and second TBS}.

[0205] In other embodiments, the first TBS and the second TBS are not included in the configuration parameters and are carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0206] Mode 4.4, TBS and sequence length are parameters affecting the uplink transmission anti-frequency offset performance in two different dimensions, and the unit of the transmission resource can be determined by the TBS and the sequence length.

[0207] In an exemplary case, when the TBS is greater than the TBS threshold and the sequence length is greater than the length threshold, the unit of the transmission resource is the first unit. When the TBS is less than or equal to the TBS threshold, and / or, when the sequence length is less than or equal to the length threshold, the unit of the transmission resource is the second unit.

[0208] In another exemplary case, when the TBS is greater than the TBS threshold and the sequence length is greater than the length threshold, the sequence is not used. And / or, when the TBS is less than or equal to the TBS threshold, or when the sequence length is less than or equal to the length threshold, the unit of the transmission resource is the first unit. And / or, when the TBS is less than or equal to the TBS threshold and the sequence length is less than or equal to the length threshold, the unit of the transmission resource is the second unit.

[0209] It can be understood that the TBS can determine the coding rate of channel coding. The higher the coding rate, the greater the influence of the signal by frequency offset. Therefore, when the TBS is large, a unit with a smaller time length can be selected to improve the anti-frequency offset performance.

[0210] In another possible implementation, the first node can determine the unit of the transmission resource according to the RV. Determining the unit of the transmission resource according to the RV can include the following four methods: Method 5.1, Method 5.2, Method 5.3, Method 5.4.

[0211] Method 5.1, when the RV is the first RV, the unit of the transmission resource is the first unit. And / or, when the RV is the second RV, the unit of the transmission resource is the second unit. Among them, the number of non-repeated values in the first RV is less than the number of non-repeated values in the second RV. The time length of the first unit is less than the time length of the second unit.

[0212] Exemplarily, if the RV is [0, 1, 2, 3], the number of non-repeated values in the RV is 4. If the RV is [0, 2, 0, 2], the number of non-repeated values in the RV is 2.

[0213] It should be noted that the embodiments of the present disclosure do not limit the RV. For example, the RV can include at least one of the following: [a, a, a, a], [a, b, a, b], [a, b, c, d], where the values of a, b, c, d are any integer from 0 to 3.

[0214] In some embodiments, at least one of the first RV and the second RV can be included in the configuration parameters.

[0215] For example, the configuration parameters include: RV{RV1, the first RV, and the second RV}.

[0216] In some other embodiments, the first RV and the second RV are not included in the configuration parameters and are carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0217] In some embodiments, the configuration parameters may further include the number of transmission repetitions.

[0218] In Mode 5.2, when the number of transmission repetitions is the first number of repetitions and the RV is the first RV, the unit of the transmission resource is the first unit. And / or, when the number of transmission repetitions is the first number of repetitions and the RV is the second RV, the unit of the transmission resource is the second unit. Among them, the number of non-repeated values in the first RV is less than the number of non-repeated values in the second RV. The time length of the first unit is less than the time length of the second unit.

[0219] In Mode 5.3, when the number of transmission repetitions is greater than the repetition number threshold and the RV is the first RV, the unit of the transmission resource is the first unit. And / or, when the number of transmission repetitions is less than or equal to the repetition number threshold and the RV is the first RV, the unit of the transmission resource is the second unit. And / or, when the number of transmission repetitions is greater than the repetition number threshold and the RV is the second RV, the unit of the transmission resource is the second unit. When the number of transmission repetitions is less than or equal to the repetition number threshold and the RV is the second RV, the unit of the transmission resource is the third unit. Among them, the number of non-repeated values in the first RV is greater than the number of non-repeated values in the second RV, and the number of non-repeated values in the second RV is greater than the number of non-repeated values in the third RV. The time length of the first unit is less than the time length of the second unit, and the time length of the second unit is less than the time length of the third unit.

[0220] It should be noted that there is no limitation on the setting method of the first number of repetitions and the repetition number threshold. For example, the repetition number threshold can be a predefined value (such as encoded in a device, device, or chip). Another example is that the repetition number threshold can be the maximum sequence length supported by the first node. Another example is that the repetition number threshold can be a value configured by the second node.

[0221] In some embodiments, at least one of the first number of repetitions and the repetition number threshold can be included in the configuration parameters.

[0222] For example, the configuration parameters include: the number of repetitions {the number of repetitions 1, the first number of repetitions}.

[0223] In other embodiments, at least one of the first number of repetitions and the repetition number threshold is not included in the configuration parameters and is carried in any of the following signaling: SI, RRC message, MAC CE, DCI.

[0224] In Mode 5.4, the supported sequence length can be determined based on the RV and the number of transmission repetitions, and the unit of the transmission resource can be determined based on the supported sequence length. Among them, the supported sequence length is the value obtained by dividing the number of transmission repetitions by the number of non-repeated values in the RV.

[0225] Exemplarily, suppose the number of transmission repetitions is 8. When the RV takes the value of [a, a, a, a], the supported sequence length is 8. When the RV takes the value of [a, b, a, b], the supported sequence length is 4. When the RV takes the value of [a, b, c, d], the supported sequence length is 2.

[0226] In some embodiments, the configuration parameter may further include the duration for which the sequence is applied to the transmission resource.

[0227] In a possible implementation, the first node may determine the unit of the transmission resource according to the duration for which the sequence is applied to the transmission resource. Determining the unit of the transmission resource according to the duration for which the sequence is applied to the transmission resource may include the following two methods: Method 6.1 and Method 6.2.

[0228] Method 6.1, when the duration for which the sequence is applied to the transmission resource is less than the time threshold, the unit of the transmission resource is the first unit. And / or, when the duration for which the sequence is applied to the transmission resource is greater than the time threshold, the unit of the transmission resource is the second unit. And / or, when the duration for which the sequence is applied to the transmission resource is equal to the time threshold, the unit of the transmission resource is the first unit or the second unit. Herein, the time length of the first unit is less than that of the second unit.

[0229] Method 6.2, when the duration is less than or equal to the first duration threshold, the unit of the transmission resource is the first unit. And / or, when the duration is less than or equal to the second duration threshold and greater than the first duration threshold, the unit of the transmission resource is the second unit. And / or, when the duration is greater than the second duration threshold, the sequence is not used. Herein, the first duration threshold is less than the second duration threshold. The time length of the first unit is less than that of the second unit, and the time length of the second unit is less than that of the third unit.

[0230] It should be noted that the embodiments of the present disclosure do not limit the setting methods of the above-mentioned duration threshold, first duration threshold, and second duration threshold. For example, the duration threshold may be a predefined value (such as encoded in a device, component, or chip). For another example, the duration threshold may be the duration supported by the first node. For yet another example, the duration threshold may be the value configured by the second node.

[0231] In some embodiments, at least one of the duration threshold, first duration threshold, and second duration threshold may be included in the configuration parameter.

[0232] For example, the configuration parameter includes: duration {duration 1, duration threshold}.

[0233] In some other embodiments, at least one of the duration threshold, the first duration threshold, and the second duration threshold is not included in the configuration parameter and is carried in any one of the following signaling: SI, RRC message, MAC CE, DCI.

[0234] In some embodiments, the duration to which the sequence is applied to the transmission resource is related to the sequence length.

[0235] It can be understood that the shorter the duration, the shorter the sequence length that can be used. Therefore, in the case of a shorter duration, the anti-frequency offset performance can be improved by selecting a unit with a smaller time length.

[0236] In a possible implementation manner, the first unit is one or more symbols, and the second unit is one or more time slots. And / or, the first unit is one symbol, and the second unit is multiple symbols. And / or, the first unit is one time slot, and the second unit is multiple time slots. And / or, the first unit is one or more REs, and the second unit is one or more symbols. And / or, the first unit is one or more REs, and the second unit is one or more time slots.

[0237] The above is an introduction to the process of determining the unit of the transmission resource according to the specific parameters of the unit of the transmission resource, the unit identifier of the transmission resource, and the configuration parameter. Next, the process of determining the unit of the transmission resource according to the capability information will be introduced.

[0238] In a possible implementation manner, the first node can determine the unit of the transmission resource according to the configuration parameter and the capability information.
