[0003] The present application belongs to the field of communication technology, and specifically relates to a transmission method, a terminal, and a network-side device. Background Art

[0004] When communicating with the terminal, the network-side device can send or receive multiple transmission objects in the form of frequency division multiplexing (FDM) or discrete frequency domain.

[0037] The transmission method, terminal, and network-side device provided in the embodiments of the present application are described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0038] As shown in FIG2 , an embodiment of the present application provides a transmission method 200 , which can be executed by a terminal. In other words, the transmission method can be executed by software or hardware installed in the terminal. The transmission method includes the following steps.

[0039] S202: The terminal determines a transmission mode of one or at least two transmission objects, where the transmission mode includes transmission using the same or different modes, or the transmission mode is related to at least one of the waveform, initialization parameter, scrambling mode, sequence, phase or rotation phase used when transmission is performed using the same or different modes, and the transmission object includes a signal or a channel or a part of a signal or a part of a channel, and at least two transmission objects are transmitted in the form of frequency division multiplexing FDM or discrete frequency domain.

[0040] S204: The terminal transmits one or at least two transmission objects according to the transmission mode.

[0041] When a terminal transmits (sends or receives) multiple transmission objects in the form of FDM or discrete frequency domain, it can determine the transmission mode (sending mode or receiving mode) for one or at least two transmission objects, and then transmit one or at least two transmission objects using the determined transmission mode.

[0042] The at least two transmission objects mentioned above can be part of the transmission objects among the multiple transmission objects, or can be all of the multiple transmission objects, which is not specifically limited here. For each transmission object, the transmission object can be a signal or a channel or a part of a signal or a part of a channel. Accordingly, the at least two transmission objects can be at least two signals or at least two channels or a part of at least two signals or a part of at least two channels, or can also be any combination of at least one signal, at least one channel, a part of at least one signal, and a part of at least one channel. For example, the at least two transmission objects can be two signals, or two channels, or two parts of a signal, or two parts of a channel, or a part of one signal and a part of another signal, or a part of one signal and a part of a channel, or a part of one channel and a part of another channel, or a signal and a part of another signal, or a channel and a part of another channel, etc., and examples will not be given one by one here.

[0043] Optionally, in some embodiments, the transmission object may include but is not limited to at least one of the following:

[0044] Synchronization signal; Broadcast signal; Synchronization Signal and PBCH block (SSB); Master Information Block (MIB); Random Access Occasion (RO); Paging Occasion (PO); Paging radio frame (PF); Physical Uplink Shared Channel (PUSCH) occasion; Carrier; Search Space set.

[0045] Optionally, at least two object transmission objects may be the same signal, for example, both are synchronization signals or broadcast channels, such as both are PUCCHs.

[0046] The transmission mode of a transmission object may include at least one of a waveform, initialization parameters, scrambling mode, sequence, phase or rotation phase used when transmitting the object.

[0047] The transmission methods of the at least two transmission objects may be to transmit the at least two transmission objects using the same method, or to transmit the at least two transmission objects using different methods, or to transmit the at least two transmission objects using the same method using at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase, or to transmit the at least two transmission objects using different methods. In this way, when transmitting the at least two transmission objects, the terminal can select an appropriate transmission method, thereby reducing PAPR and ensuring coverage.

[0048] In the case of transmitting at least two transmission objects in different manners, optionally, in some embodiments, the transmission in different manners may satisfy at least one of the following:

[0049] At least two transmission objects use different waveforms;

[0050] At least two transport objects are generated based on different initialization parameters;

[0051] At least two transmission objects use different scrambling methods;

[0052] At least two transfer objects use different sequences;

[0053] At least two transmission objects use different phases or phase rotations.

[0054] The above-mentioned waveform may include but is not limited to at least one of a multi-carrier waveform, a single-carrier waveform, an orthogonal time frequency space modulation (OTFS) waveform, a low power waveform, a chirp waveform, a frequency modulated continuous wave (FMCW) waveform, a linear frequency modulation (LFM) waveform, an amplitude modulation waveform, a frequency modulation waveform, and a phase modulation waveform. Among them, the multi-carrier waveform may be, for example, cyclic prefix orthogonal frequency division multiplexing (CP-OFDM), filter-bank multicarrier (FBMC), generalized frequency division multiplexing (GFDM), universal filter multicarrier (UFMC), filter-orthogonal frequency division multiplexing (F-OFDM), etc. Examples of single-carrier waveforms include Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM), constant envelope waveforms, and single-carrier frequency domain equalization (SC-FDE). OTFS waveforms are primarily used for high speed or large payloads. Low-power waveforms include ultra-wideband (UWB).

[0055] At least two transmission objects are generated based on different initialization parameters, for example, they may be generated based on different N_ID1, N_ID2, Physical Cell Identifier (PCI), or Index.

[0056] At least two transmission objects use different scrambling methods, for example, they may be scrambled using different scrambling code sequences.

[0057] At least two transmission objects use different sequences, for example, different types of sequences (such as golden sequence, m sequence, zc sequence), or the types of sequences used may be the same but different sequences.

[0058] When determining the transmission mode for at least two transmission objects, a terminal may use at least one of an implicit method and an explicit method. The implicit method may involve the terminal determining the transmission mode based on relevant information during the transmission of the at least two transmission objects and the correspondence between the relevant information and the transmission mode. The explicit method may involve the terminal determining the transmission mode based on instructions from a network-side device. The transmission mode determined using the implicit or explicit method may include using the same or different modes to transmit the at least two transmission objects, or at least one of the waveform, initialization parameters, scrambling mode, sequence, phase, or rotation phase used when transmitting the at least two transmission objects using the same or different modes.

[0059] Optionally, in some implementations, when the transmission mode is determined implicitly, the terminal determines the transmission modes of at least two transmission objects, which may include at least one of the following (1) to (15):

[0060] (1) The transmission mode is determined based on the frequency band, subband, band combination or frequency range (FR).

[0061] There is a correspondence between the frequency band, sub-band, band combination or frequency range and the transmission mode. In some embodiments, there is a predefined correspondence between different bands or subbands or bandCombination or FRs and transmission using the same or different modes. For example, when working in the millimeter wave frequency band, different modes (different waveforms, different initialization parameters, different scrambling sequences, different signal sequences, different phases, different phase rotations, at least one of them) can be used to transmit at least two transmission objects, and when working in FR1 or a low frequency band (such as 1 GHz), the same mode (the same waveform, the same initialization parameters, the same scrambling sequence, the same signal sequence, the same phase, the same phase rotation, at least one of them) can be used to transmit at least two transmission objects. Alternatively, it is also possible to work in the millimeter wave frequency band and use the same mode to transmit at least two transmission objects, and work in FR1 or a low frequency band (such as 1 GHz) and use different modes to transmit at least two transmission objects.

[0062] In some embodiments, a predefined correspondence exists between different bands, subbands, bandCombinations, or FRs and at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used for transmission. For example, when operating in the FR2-2 or FR2-3 frequency band, at least two transmission objects can respectively perform phase rotation 1 or phase rotation 2, and when operating in the FR2-1 frequency band, at least two transmission objects can respectively perform phase rotation 3 or phase rotation 4. Alternatively, when operating in the FR2-2 or FR2-3 frequency band, at least two transmission objects can respectively perform phase rotation 3 or phase rotation 4, and when operating in the FR2-1 frequency band, at least two transmission objects can respectively perform phase rotation 1 or phase rotation 2.

[0063] In some embodiments, each band or subband or bandCombination or FR can be associated with multiple transmission modes (such as transmission using different modes, transmission using the same mode, at least one of the waveform, initialization parameter, scrambling mode, sequence, phase or rotation phase used when transmitting using different modes, and at least one of the waveform, initialization parameter, scrambling mode, sequence, phase or rotation phase used when transmitting using the same mode). The specific transmission mode to be used can be further determined based on other factors (such as base station type, etc.).

[0064] For example, on a certain band, subband, bandCombination, or FR, it is necessary to support base stations of multiple types or capabilities. For example, it is necessary to support some local base stations with relatively weak capabilities (for example, a maximum transmit power of only 24dBm), and it is also necessary to support some global base stations or ordinary base stations with relatively strong capabilities (for example, a maximum transmit power of 38dBm or even unlimited). Although the two base stations operate on the same band, subband, bandCombination, or FR, they may use different transmission modes. When determining the transmission mode, for example, if the base station type is a local base station, different modes can be used to transmit at least two transmission objects. If the base station type is a global base station or an ordinary base station, the same mode can be used to transmit at least two transmission objects. Furthermore, for each base station type, when transmitting at least two transmission objects, at least one of the waveform, initialization parameter, scrambling mode, sequence, phase, or rotation phase used has a corresponding relationship with the band, subband, bandCombination, or FR. That is to say, when determining the transmission mode, the terminal can first determine whether to use the same or different mode for transmission according to the base station type, and then determine at least one of the waveform, initialization parameters, scrambling mode, sequence, phase or rotation phase used during transmission according to the band or subband or bandCombination or FR.

[0065] (2) Determine the transmission method based on the scenario or the purpose of at least two transmission objects.

[0066] The scenario or purpose corresponds to the transmission mode. The scenario may be, for example, a terrestrial network (TN) or a non-terrestrial network (NTN). The purposes of the at least two transmission objects may be, for example, cell search, assisting in determining timing advance (TA), validating the validity of the TA, beam management (BM), measurement, persistent objects, mandatory transmission objects, on-demand triggered objects, or on-demand transmission objects.

[0067] Taking the example of determining the transmission method for at least two transmission objects based on the scenario, for example, the at least two transmission objects may be transmitted using the same method in a TN scenario, and transmitted using different methods in an NTN scenario. Alternatively, the at least two transmission objects may be transmitted using different methods in a TN scenario, and transmitted using the same method in an NTN scenario.

[0068] (3) Determine the transmission mode according to type information of at least two transmission objects or attribute information corresponding to at least two transmission objects.

[0069] The type information or attribute information of at least two transmission objects corresponds to the transmission mode.

[0070] The type information of the at least two transmission objects may include but is not limited to at least one of the following:

[0071] At least two transmission objects corresponding to the purpose (e.g., for cell search, for assisting in determining Timing Advance (TA), for validation, for TA validation, for beam management (BM), measurement, a persistent object, or an object that is mandatory (mandatory transmission can also be interpreted as inevitable transmission or must be considered), an object that is triggered on demand, or an object that is transmitted on demand, etc.); in particular, transmission can be interpreted as sending or receiving;

[0072] Terminal types corresponding to at least two transmission objects (e.g., Reduced Capability (RedCap) terminals, smart phones, different types of IoT devices, different types of Ambient Internet of Things (A-IoT) devices, terminals of different power levels, and different cyclic prefix extensions (CPE));

[0078] Duplex modes corresponding to at least two transmission objects (such as full duplex, half duplex, etc.);

[0079] Access modes or access methods corresponding to at least two transmission objects;

[0080] At least two cells corresponding to the transmission objects (such as macro cells and small cells);

[0081] The types of Transmission Reception Points (TRPs) corresponding to at least two transmission objects (e.g., multi-TRP (MTRP), single TRP);

[0082] Waveforms corresponding to at least two transmission objects (e.g., cyclic prefix-orthogonal frequency division multiplexing (CP-OFDM) waveform, discrete Fourier transform-spread-orthogonal frequency division multiplexing (DFT-S-OFDM) waveform, orthogonal time and frequency space (OTFS) waveform);

[0083] RAN services corresponding to at least two transmission objects (such as sensing services, NTN services, low-power synchronization signal (LP-SS) services, and wake-up signal (WUS) services);

[0084] Network energy-saving characteristics corresponding to at least two transmission objects (e.g., related to the length of the SSB cycle, or whether paging, System Information Block (SIB), Random Access Channel (RACH), etc. are enabled, and the period of paging, SIB, or RACH);

[0085] SSB cycles corresponding to at least two transmission objects;

[0086] a measurement period corresponding to at least two transmission objects;

[0087] Other related signal periods corresponding to at least two transmission objects (such as paging, SIB or RACH periods);

[0088] The higher-layer protocol characteristics corresponding to at least two transport objects (for example, whether the higher-layer protocol has enabled special services, such as data plane, NPN, or simplified protocol stack, etc.).

[0089] The attribute information of at least two transmission objects includes but is not limited to at least one of the following:

[0090] BWP information, time domain resource information (such as time domain resource blocks), frequency domain resource information (such as frequency domain resource blocks), duplex mode information, access mode or method, cell type information, TRP type information, waveform information, RAN service information, energy-saving feature information, cycle information, high-layer feature information, transmission information, destination information, terminal information, network information.

[0091] Exemplarily, the transmission information may include at least one of the following:

[0092] Whether the transmission object is transmitted multiple times in the time domain, whether the transmission time window of the transmission object contains multiple transmission objects, whether the transmission object is transmitted multiple times in the frequency domain, whether multiple transmission objects are contained in a specific bandwidth, whether the transmission object is transmitted using continuous time domain, whether the transmission object is transmitted using continuous frequency domain (for example, if it is transmitted multiple times in the frequency domain, whether it is transmitted on continuous resources, and whether there is an interval), whether the transmission object is transmitted using discrete time domain resources (such as using interlace transmission), whether the transmission object is transmitted using discrete frequency domain resources (such as using interlace transmission), whether the reference signal sequence corresponding to the multiple transmission objects is transmitted in the time domain, and whether the transmission time window of the transmission object is Whether it contains multiple reference signal sequences corresponding to transmission objects, whether the reference signal sequence corresponding to the transmission object is transmitted multiple times in the frequency domain, whether the reference signal sequence corresponding to multiple transmission objects is contained in a specific bandwidth, whether the reference signal sequence corresponding to the transmission object is transmitted using continuous time domain, whether the reference signal sequence corresponding to the transmission object is transmitted using continuous frequency domain (for example, if it is transmitted multiple times in the frequency domain, whether it is transmitted on continuous resources, and whether there is an interval), whether discrete time domain resources are used to transmit the reference signal sequence corresponding to the transmission object (such as using interlace transmission), and whether discrete frequency domain resources are used to transmit the reference signal sequence corresponding to the transmission object (such as using interlace transmission).

[0093] In some embodiments, there is a predefined correspondence between different types of information or attribute information and transmission using the same or different methods. For example, at least two transmission objects corresponding to type 1 are transmitted using different methods (i.e., at least one of different waveforms, different initialization parameters, different scrambling sequences, different signal sequences, different phases, and different phase rotations), and at least two transmission objects corresponding to type 2 are transmitted using the same method (i.e., at least one of the same waveform, same initialization parameters, same scrambling sequence, same signal sequence, same phase, and same phase rotation). Alternatively, at least two transmission objects corresponding to type 1 may be transmitted using the same method, and at least two transmission objects corresponding to type 2 may be transmitted using different methods.

[0094] In some embodiments, a predefined correspondence exists between different types or attribute information and at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or phase rotation used for transmission. For example, at least two transmission objects corresponding to type 1 may each undergo phase rotation 1 or phase rotation 2, and at least two transmission objects corresponding to type 2 may each undergo phase rotation 3 or phase rotation 4.

[0095] (4) Determine the transmission mode according to the terminal's moving speed.

[0096] There is a correspondence between the moving speed and the transmission mode. In some embodiments, there is a predefined correspondence between the moving speed and the transmission using the same or different modes, and there may also be a predefined correspondence between the moving speed and at least one of the waveform, initialization parameter, scrambling mode, sequence, phase or rotation phase used for transmission. Among them, for the terminal, the terminal can know its own moving speed, and then determine the transmission mode of at least two transmission objects based on the correspondence between the moving speed and the transmission mode. For the network side device, the moving speed of the terminal can be obtained based on the measurement of one or more physical random access channels (PRACH) or sounding reference signals (SRS) or phase tracking reference signals (PT-RS) or other uplink signal transmissions or based on the information reported by the terminal, and then based on the correspondence between the moving speed and the transmission mode, the transmission mode of at least two transmission objects is determined.

[0097] For example, when the terminal's moving speed does not exceed X km / h, the transmission methods of at least two transmission objects are transmitted using the same method. When the terminal's moving speed is less than X km / h, the transmission methods of at least two transmission objects are transmitted using different methods. Alternatively, when the terminal's moving speed does not exceed X km / h, the transmission methods of at least two transmission objects are transmitted using different methods. When the terminal's moving speed is less than X km / h, the transmission methods of at least two transmission objects are transmitted using the same method.

[0098] (5) Determine the transmission method based on the time information.

[0099] The time information corresponds to the transmission mode, and can be, for example, a frame index, a subframe index, a slot index, or a time division duplex (TDD) configuration.

[0100] In some embodiments, the time information may have a predefined correspondence with transmission using the same or different methods, or may have a predefined correspondence with at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase used for transmission.

[0101] (6) Determine the transmission mode based on the frequency domain information.

[0102] Frequency domain information has a corresponding relationship with the transmission mode. Frequency domain information can be, for example, bandwidth, band, band combination, raster, step size, and frequency range.

[0103] In some embodiments, there may be a predefined correspondence between the frequency domain information and transmission using the same or different methods, or there may be a predefined correspondence between the frequency domain information and at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used for transmission. For example, when the bandwidth is greater than M1, the transmission methods of at least two transmission objects are transmitted using different methods. When the bandwidth is less than M1, the transmission methods of at least two transmission objects are transmitted using the same method. Alternatively, when the bandwidth is greater than M1, the transmission methods of at least two transmission objects are transmitted using the same method. When the bandwidth is less than M1, the transmission methods of at least two transmission objects are transmitted using different methods.

[0104] (7) A transmission mode is determined based on an interval between at least two transmission objects.

[0105] The interval between at least two transmission objects has a corresponding relationship with the transmission mode. The interval between at least two transmission objects can be a time interval or a frequency interval.

[0106] In some embodiments, the interval between at least two transmission objects may have a predefined correspondence with the transmission using the same or different methods, or may have a predefined correspondence with at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used for transmission. For example, when the interval between at least two transmission objects is greater than M2, the transmission methods of the at least two transmission objects are transmitted using different methods. When the interval between at least two transmission objects is less than M2, the transmission methods of the at least two transmission objects are transmitted using the same method. Alternatively, when the interval between at least two transmission objects is greater than M2, the transmission methods of the at least two transmission objects are transmitted using the same method. When the interval between at least two transmission objects is less than M2, the transmission methods of the at least two transmission objects are transmitted using different methods.

[0107] (8) Determine the transmission method based on the spectrum deployment pattern.

[0108] The spectrum deployment mode corresponds to the transmission mode. The spectrum deployment mode can be, for example, FDD, TDD, or enhanced duplex mode.

[0109] In some embodiments, the spectrum deployment mode may have a predefined correspondence with transmissions using the same or different methods, or may have a predefined correspondence with at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used for transmission. For example, if the spectrum deployment mode is FDD, the transmission modes of at least two transmission objects are transmitted using different methods; if the spectrum deployment mode is TDD, the transmission modes of at least two transmission objects are transmitted using the same method; if the spectrum deployment mode is FD, the transmission modes of at least two transmission objects are transmitted using different methods, and the specific waveform, initialization parameter, scrambling sequence, signal sequence, phase, phase rotation used are related to the deployment mode.

[0110] (9) Determine the transmission mode based on output power or transmit power.

[0111] Output power or transmit power corresponds to a transmission mode. The output power or transmit power can have a predefined correspondence with transmissions using the same or different modes, or with at least one of the waveform, initialization parameters, scrambling mode, sequence, phase, or rotation phase used in transmission. For example, when the transmit power is greater than a certain value, the transmission modes of at least two transmission objects are different. When the transmit power is less than a certain value, the transmission modes of at least two transmission objects are the same.

[0112] (10) The transmission mode is determined based on the configuration of the random access channel (such as PRACH in 5G), the resources of the random access channel or the preamble format.

[0113] There is a corresponding relationship between the configuration of the random access channel, the resources of the random access channel or the preamble format and the transmission mode.

[0114] In some embodiments, there may be a predefined correspondence between the configuration of the random access channel, the resources of the random access channel, or the preamble format and transmission using the same or different methods, or there may be a predefined correspondence between the configuration of the random access channel, the resources of the random access channel, or the preamble format and at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used for transmission. For example, the base station configures the PRACH resources or the preamble format used for the UE, and the terminal determines the transmission method of at least two transmission objects based on the transmission resources or preamble format of the PRACH used and the predefined relationship. For example, if the preamble format is a short sequence, the transmission method of at least two transmission objects is to use the same method for transmission; if the preamble format is a long sequence, the transmission method of at least two transmission objects is to use different methods for transmission. Alternatively, different restriction sets may correspond to different waveforms, initialization parameters, scrambling sequences, signal sequences, phases, and phase rotations, and at least one of the waveform, initialization parameters, scrambling sequence, signal sequence, phase, and phase rotation used for transmission is determined according to the restriction set.

[0115] (11) Determine the transmission mode based on the time domain configuration or the frequency domain configuration.

[0116] The time domain configuration or the frequency domain configuration has a corresponding relationship with the transmission mode. In some embodiments, the time domain configuration or the frequency domain configuration may have a predefined corresponding relationship with the transmission using the same or different modes, or may have a predefined corresponding relationship with at least one of the waveform, initialization parameter, scrambling mode, sequence, phase or rotation phase used for transmission. For example, when a certain channel raster or channel raster+offset or channel raster-offset or sync raster or the corresponding position on the sync raster+offset or sync raster-offset is used for the transmission of at least two transmission objects, the transmission mode of at least two transmission objects is to use the same transmission mode. Alternatively, different modes may be used for transmission. Furthermore, at least one of the waveform, initialization parameter, scrambling sequence, signal sequence, phase, and phase rotation used is related to the corresponding position on the channel raster or channel raster+offset or channel raster-offset or sync raster or the sync raster+offset or sync raster-offset used.

[0117] (12) Determine the transmission mode based on whether the transmission on one or more channels, carriers, part of the bandwidth or cell is repeated.

[0118] Whether transmission on one or more channels, carriers, partial bandwidths, or cells is repeated corresponds to the transmission mode. Optionally, in some embodiments, whether transmission on one or more channels, carriers, partial bandwidths, or cells is repeated corresponds to whether the same or different transmission modes are used. For example, if transmission on a cell is repeated, the transmission modes of at least two transmission objects are transmitted using the same mode; if transmission on a cell is not repeated, the transmission modes of at least two transmission objects are transmitted using different modes.

[0119] (13) Determine the transmission mode based on the number of repetitions of transmission on one or more channels, carriers, part of the bandwidth or cell.

[0120] The number of repetitions of transmission on one or more channels, carriers, partial bandwidths, or cells corresponds to the transmission mode. Optionally, in some embodiments, the number of repetitions of transmission on one or more channels, carriers, partial bandwidths, or cells corresponds to the use of the same or different transmission modes. For example, if the number of repetitions of transmission on a cell is greater than a certain value, the transmission modes of at least two transmission objects are transmitted using the same mode; if the number of repetitions of transmission on a cell is less than a certain value, the transmission modes of at least two transmission objects are transmitted using different modes.

[0121] (14) Determine the transmission method based on the number of transmission objects.

[0122] The number of transmission objects has a corresponding relationship with the transmission mode. Optionally, in some embodiments, the number of transmission objects may have a predefined corresponding relationship with the transmission using the same or different modes. For example, if the number of transmission objects transmitted in the FDM mode exceeds N, the transmission modes of at least two transmission objects are transmitted using different modes; if the number of transmission objects transmitted in the FDM mode exceeds N, the transmission modes of at least two transmission objects are transmitted using the same mode. Alternatively, it may be that if the number of transmission objects transmitted in the FDM mode exceeds N, the transmission modes of at least two transmission objects are transmitted using the same mode; if the number of transmission objects transmitted in the FDM mode exceeds N, the transmission modes of at least two transmission objects are transmitted using different modes.

[0123] (15) Determine the transmission mode according to the multiple access mode.

[0124] The multiple access mode has a corresponding relationship with the transmission mode. Optionally, in some embodiments, there is a predefined corresponding relationship between whether the multiple access mode is used and whether the same or different modes are used for transmission. For example, if a non-orthogonal multiple access mode is used (such as multi-user multiple input multiple output (MU-MIMO)), the transmission mode of at least two transmission objects is to use the same transmission mode; if the non-orthogonal multiple access mode is not used, the transmission mode of at least two transmission objects is to use different transmission modes.

[0125] Optionally, in some implementations, when the transmission mode is determined in an explicit manner, the terminal determining the transmission modes of at least two transmission objects may include:

[0126] The terminal receives first information, where the first information indicates a transmission mode;

[0127] The terminal determines a transmission mode according to the first information.

[0128] The first information includes but is not limited to at least one of the following:

[0129] Downlink synchronization related signals;

[0131] System Information Block (SIB);

[0132] public messages or channels;

[0133] Downlink Control Information (DCI) or Physical Downlink Control Channel (PDCCH);

[0134] A signal or channel scrambled by a specific Radio Network Temporary Identifier (RNTI);

[0135] Specific RNTI;

[0136] Medium Access Control-Control Element (MAC-CE);

[0137] Radio Resource Control (RRC).

[0138] The downlink synchronization related signal includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or a physical broadcast channel demodulation reference signal (PBCH DMRS). In the case where the first information includes the downlink synchronization related signal, the first information indicates the transmission mode, which may include: indicating the transmission mode through the ID of the synchronization sequence, and the ID of the synchronization sequence includes but is not limited to N_ID (1) or N_ID (2). Optionally, indicating the transmission mode through the ID of the synchronization sequence may include: the ID of the synchronization sequence and the transmission mode have a corresponding relationship, that is, indicating the transmission mode through the corresponding relationship between the ID of the synchronization sequence and the transmission mode. When the terminal determines the transmission mode of at least two transmission objects according to the downlink synchronization related signal, the corresponding transmission mode can be determined according to the corresponding relationship between the ID of the synchronization sequence and the transmission mode.

[0139] The MIB may be a representation of a system message in a 6G or any future mobile communication system. In the case where the first information includes the MIB, the first information indicates a transmission mode and may include at least one of the following:

[0140] The MIB carries parameters indicating the transmission mode; for example, there is a corresponding bit in the MIB, and the bit can carry parameters indicating the transmission mode;

[0141] The transmission mode is indicated by a specific value, where the specific value is a specific value indicated by a subcarrier offset parameter between a downlink synchronization related signal and a reference grid or reference point (e.g., a grid), or a specific value indicated by a subcarrier offset parameter between an SSB and a reference grid or reference point (e.g., a common resource block grid);

[0142] The transmission mode is indicated by controlling the resource configuration or the monitoring opportunity configuration, and the control resource configuration or the monitoring opportunity configuration has a corresponding relationship with the transmission mode.

[0143] In the case where the transmission mode is indicated by the control resource configuration or the monitoring timing configuration, for example, the transmission mode can be indicated by the control resource set CORESET#0 configuration or the monitoring timing configuration of the Type 0-PDCCH CSS (Physical Downlink Control Channel Common Search Space), and the monitoring timing configuration of the CORESET#0 configuration or the Type 0-PDCCH CSS has a corresponding relationship with the transmission mode, wherein the control resource configuration or the monitoring timing configuration is related to at least one of the carrier spacing combination, the minimum bandwidth, the SSB, the reuse pattern and frequency band of CORESET#0, the above-mentioned specific value, the specific system frame number, and the spare spare bit in the MIB. Optionally, in some embodiments, the transmission mode can be indicated by configuring the CORESET resources or Search Space or PDCCH monitoring timing (MO) at a specific time-frequency domain location. For example, different waveforms can correspond to different CORESET resources or Search Space or PDCCH MO at different specific time-frequency domain locations.

[0144] When the terminal determines the transmission mode of at least two transmission objects based on the MIB, it can determine the corresponding transmission mode based on the parameters carried in the MIB, or determine the corresponding transmission mode based on a specific value, or determine the corresponding transmission mode based on the correspondence between the control resource configuration or the monitoring timing configuration and the transmission mode.

[0145] The SIB may be at least one of SIB1, RMSI, other SIBs, other system information (OSI), 6G, or system information in any future mobile communication system. When the first information includes the SIB, the first information indicates the transmission mode, which may be a signaling indication of the transmission mode carried by one or more bits in the SIB. For example, the signaling indication of the transmission mode carried by one or more bits in SIB1 or OSI. When the terminal determines the transmission mode of at least two transmission objects based on the SIB, it may determine the corresponding transmission mode based on the indication of the signaling in the SIB.

[0146] The common message or channel may be a message or channel that can be received by multiple terminals, such as a common physical downlink shared channel (Common PDSCH), typically Msg2 (i.e., random access response (RAR)), Msg4, and MsgB PDSCH. When the first information includes a common message or channel, the first information indicates a transmission mode and may include at least one of the following:

[0147] The transmission mode is carried by a bit or field in a common message or channel; the bit or field can repurpose an existing field, or a new field can be introduced;

[0148] The transmission mode is indicated by a common message or the logical channel ID corresponding to the channel;

[0149] The transmission mode is indicated by the uplink grant (UL grant) information of a common message or channel; for example, the transmission mode is indicated by the UL grant information in Msg2;

[0150] The transmission mode is indicated by the DMRS resources of the common message or channel; for example, the transmission mode is indicated by the DMRS resources of the common PDSCH;

[0151] The transmission mode is indicated by a scrambling sequence of a common message or channel; for example, the transmission mode is indicated by a scrambling sequence of a common PDSCH.

[0152] When the terminal determines the transmission mode of at least two transmission objects based on a common message or channel, it can determine the corresponding transmission mode based on an indication of at least one of the bits or fields in the common message or channel, the logical channel ID corresponding to the common message or channel, the uplink authorization information of the common message or channel, the DMRS resources of the common message or channel, and the scrambling sequence of the common message or channel.

[0153] The DCI or PDCCH may be Common DCI or Common PDCCH, typically Msg2, Msg4, MsgB PDCCH, SIB1 PDCCH, or PDCCH scheduling retransmission of Msg3. When the first information includes DCI or PDCCH, the first information indicates a transmission mode and may include at least one of the following:

[0154] The transmission mode is carried by an information bit or field in the DCI or PDCCH. For example, the transmission mode can be directly carried by an information bit or field in the Common PDCCH or Common DCI. The bit or field can repurpose an existing field or introduce a new field.

[0155] The transmission mode is indicated by the DMRS resources of the DCI or PDCCH; for example, the transmission mode can be indicated by the DMRS resources of the Common PDCCH;

[0156] The transmission mode is indicated by a scrambling sequence of a DCI or PDCCH. For example, the transmission mode may be indicated by a scrambling sequence of a Common PDCCH.

[0157] When the terminal determines the transmission mode of at least two transmission objects based on DCI or PDCCH, it can determine the corresponding transmission mode based on the indication of at least one of the information bits or fields of DCI or PDCCH, DMRS resources of DCI or PDCCH, and scrambling sequences of DCI or PDCCH.

[0158] In the case where the first information includes a signal or channel scrambled by a specific RNTI, or in the case where the first information includes a specific RNTI, the specific RNTI is determined by at least one of the following methods:

[0159] Configuring or indicating a specific RNTI; for example, a base station configuring or indicating a specific RNTI;

[0160] Determined or generated based on the first RNTI and the offset.

[0161] In the case where the specific RNTI is determined or generated based on the first RNTI and the offset, the determination or generation method may include at least one of the following:

[0162] Determined or generated based on a Random Access-Radio Network Temporary Identifier (RA-RNTI) and an offset;

[0163] Determine or generate based on the System Information-Radio Network Temporary Identifier (SI-RNTI) and offset;

[0164] Determining or generating based on a temporary cell-radio network temporary identifier (TC-RNTI) and an offset;

[0165] Determining or generating based on a Paging-Radio Network Temporary Identifier (P-RNTI) and an offset;

[0166] Determine or generate based on message B radio network temporary identifier (MSGB-RNTI) and offset.

[0167] When the first information includes a signal or channel scrambled by a specific RNTI, or when the first information includes a specific RNTI, the first information indicating the transmission mode may include: indicating the transmission mode via the offset, where the offset and the transmission mode have a corresponding relationship. When determining the transmission mode for at least two transmission objects based on the signal or channel scrambled by the specific RNTI, or the specific RNTI, the terminal may determine the corresponding transmission mode based on the indication of the specific RNTI, or determine the corresponding transmission mode based on the offset based on which the specific RNTI is determined or generated, and the corresponding relationship between the offset and the transmission mode.

[0168] In the case where the first information includes MAC-CE or RRC, the first information indicates a transmission mode and may include:

[0169] A transmission mode corresponding to at least one factor is configured through MAC-CE or RRC. The at least one factor may include a frequency band, a sub-band, a frequency band combination, a frequency range, a scenario, the purpose of at least two transmission objects, the type of at least two transmission objects, the attribute information corresponding to at least two transmission objects, the moving speed of the terminal, time information, frequency domain information, the interval between at least two transmission objects, the deployment mode of the spectrum, the output power or the transmit power, the configuration of the random access channel, the resources of the random access channel, the preamble format, the time domain configuration, the frequency domain configuration, whether the transmission on one or more channels, carriers, part of the bandwidth or cell is repeated or the number of repetitions, the number of transmission objects, and at least one of the multiple access modes.

[0170] For explanations of the various factors included in the above-mentioned at least one factor, reference may be made to the corresponding descriptions of these factors when the terminal determines the transmission mode according to the implicit method, and will not be repeated here.

[0171] Optionally, the correspondence between the at least one factor and the transmission mode can be configured or indicated via MAC CE or RRC. When the terminal determines the transmission mode for at least two transmission objects according to MAC-CE or RRC, the determination can be made based on the correspondence between the at least one factor configured by MAC-CE or RRC and the transmission mode. For example, if the network-side device configures the transmission modes corresponding to the FR1 frequency band and the FR2 frequency band respectively via RRC, then when the terminal operates in the FR1 frequency band, the terminal can use the transmission mode corresponding to the FR1 frequency band to transmit at least two transmission objects, and when the terminal operates in the FR2 frequency band, the terminal can use the transmission mode corresponding to the FR2 frequency band to transmit at least two transmission objects. For another example, if the network-side device configures the transmission mode corresponding to when the terminal's moving speed is less than 250 km / h and the transmission mode corresponding to when the terminal's moving speed is greater than 250 km / h respectively via RRC, then the terminal can determine to use the corresponding transmission mode to transmit at least two transmission objects based on its own moving speed.

[0172] Optionally, in some implementations, the terminal may also send its own capability information. For example, the terminal may send its own capability information to the network-side device. Upon receiving the capability information of the terminal, the network-side device may better determine how to transmit (receive or send) at least two transmission objects based on the capability information. The capability information of the terminal may include at least one of the following:

[0173] Support or use the same method to transmit at least two transmission objects;

[0174] Support or use at least two transmission objects in different ways;

[0175] Support (using the same or different methods) at least one of the waveform, initialization parameters, scrambling method, sequence, phase or rotation phase used during transmission.

[0176] Optionally, in some implementations, before entering the RRC connected state, the terminal may also transmit at least two transmission objects in the form of FDM or discrete frequency domain. In this case, the terminal determines the transmission mode of the at least two transmission objects, which may include at least one of the following:

[0177] Determine a transmission mode according to second information, where the second information includes at least one of a frequency band, a sub-band, a frequency band combination, a frequency range, a scenario, purposes of at least two transmission objects, types of at least two transmission objects, attribute information corresponding to at least two transmission objects, a moving speed of the terminal, time information, frequency domain information, an interval between at least two transmission objects, a spectrum deployment mode, output power or transmit power, a configuration of a random access channel, resources of a random access channel, a preamble format, a time domain configuration, a frequency domain configuration, whether transmission on one or more channels, carriers, partial bandwidths, or cells is repeated or the number of repetitions, the number of transmission objects, and a multiple access mode, and the second information corresponds to the transmission mode;

[0178] Use different transmission methods at different frequency domain locations;

[0179] Use different transmission methods at different time domain locations;

[0180] determining transmission in a specified mode as the transmission method;

[0181] Transmission at a specific location or time is determined as a transmission method.

[0182] For explanations of various information in the second information, please refer to the corresponding descriptions of these information when the terminal determines the transmission mode according to the implicit method, and will not be repeated here.

[0183] As an embodiment, taking the transmission object as the SSB in 5G (which can also be called any module containing at least one of the synchronization signal, broadcast signal, broadcast channel (PBCH), and other system message downlink broadcast channels) as an example, the first or first N SSBs before the terminal enters the RRC connection state can have multiple transmission modes. In this case, it is impossible for the network side device (such as the base station) to send any indication information about the transmission mode to the terminal in advance. Then, the terminal can use the following methods to determine the transmission mode of the first SSB before entering the RRC connection state:

[0184] The first method: There is a one-to-one correspondence between the SSB transmission method and the second information.

[0185] When transmitting SSB, the base station or terminal can select the corresponding transmission mode based on different second information for transmission. The second information includes frequency band, sub-band, frequency band combination, frequency range, scenario, purpose of at least two transmission objects, type of at least two transmission objects, attribute information corresponding to at least two transmission objects, terminal movement speed, time information, frequency domain information, interval between at least two transmission objects, spectrum deployment mode, output power or transmit power, random access channel configuration, random access channel resources, preamble format, time domain configuration, frequency domain configuration, whether the transmission on one or more channels, carriers, partial bandwidth or cells is repeated or the number of repetitions, the number of transmission objects, and at least one of multiple access modes.

[0186] The second method: SSBs of multiple transmission modes are transmitted separately at different frequency domain positions (such as different sync rasters or sync raster+offset positions).

[0187] The terminal can use multiple transmission modes to perform blind detection on different sync rasters or sync raster+offset positions. Optionally, the frequency domain positions of multiple transmissions of SBB of the same transmission mode are fixed.

[0188] The second method: SSB of multiple transmission modes are sent separately at different time domain positions.

[0189] The terminal can use multiple transmission modes to perform blind detection at different time domain locations. Optionally, the time domain locations of multiple transmissions of SSB of the same transmission mode are periodic.

[0190] The third method: SSB with multiple transmission modes is transmitted in a certain pattern.

[0191] For example, OTFS frames and OFDM frames may coexist in TDM or CDM mode.

[0192] The fourth method: SSB with multiple transmission modes is sent at a specific location or time.

[0193] After the terminal enters the RRC connected state, for subsequent transmission objects, the terminal may determine the transmission mode according to the implicit method or explicit method described above when transmitting. Optionally, as an embodiment, the terminal uses the default transmission mode to receive the SSB, and the SSB carries transmission mode indication information for the subsequent transmission object. The indication information may be a few bits explicitly carried in the MIB, or indicated by a specific value (such as a specific value indicated by the SSB and the subcarrier offset parameter of the reference grid or reference point). After receiving the SSB, the terminal may obtain the transmission mode indication information for the subsequent transmission object (such as SIB1), and then the terminal may use the transmission mode determined in the transmission mode indication information to transmit the subsequent transmission object. The transmission mode indication information in the SSB may indicate only the transmission mode of the next transmission object, or the transmission modes of the next N transmission objects, or the transmission mode of one or more subsequent downlink transmission objects, or the transmission mode of one or more subsequent uplink transmission objects. Optionally, if the transmission mode indication information in the SSB indicates only the transmission mode of the next transmission object (such as SIB1), then the transmission mode of the transmission objects after SIB1 may be indicated in SIB1.

[0194] Optionally, in some implementations, the terminal determining the transmission mode of at least two transmission objects may further include:

[0195] The terminal determines the transmission mode according to the transmission capability or the related capability of the transmission capability supported by the terminal, and the transmission capability or the related capability of the transmission capability has a corresponding relationship with the transmission mode.

[0196] The transmission capability may include at least one of the following: supporting or using the same method to transmit at least two transmission objects; supporting or using different methods to transmit at least two transmission objects; and supporting or using different methods to transmit at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when transmitting at least two transmission objects. When determining a transmission object based on the transmission capability, for example, if a terminal has the capability to receive a phase-rotated transmission object (e.g., SSB), then when receiving multiple transmission objects, the terminal may detect the phase-rotated transmission object, or the base station may send the phase-rotated transmission object. For another example, if a terminal has the capability to simultaneously search for or detect transmission objects (e.g., SSB) generated using different initialization parameters, then when receiving multiple transmission objects, the terminal may receive transmission objects generated using different initialization parameters, or the base station may send transmission objects generated using different initialization parameters.

[0197] The relevant capabilities of the transmission capability may be, for example, scenarios supported by the terminal (such as TN or NTN). There is a corresponding relationship between the relevant capabilities of the transmission capability and the transmission mode. For example, the terminal may support operation in both TN and NTN scenarios. In this case, the transmission objects of different scenarios may be generated using different methods, so that the terminal can receive or send at least two transmission objects generated using different methods, or the base station can send or receive at least two transmission objects generated using different methods.

[0198] Optionally, in some implementations, when transmitting at least one transmission object, the terminal may further include:

[0199] When at least one of the at least one transmission object includes at least a first part and a second part, the first part is transmitted using DFT-s-OFDM and the second part is transmitted using CP-OFDM.

[0200] The at least one transmission object here may be one or more of the at least two transmission objects in S202, in which case the at least one transmission object is transmitted in the form of FDM or discrete frequency domain. Alternatively, the at least one transmission object may be another transmission object other than the at least two transmission objects in S202, in which case the at least one transmission object is not required to be transmitted in the form of FDM or discrete frequency domain.

[0201] For example, for an SSB, when the terminal transmits the SSB, part of the SSB (such as PBCH or PBCH DMRS) can be transmitted using DFT-s-OFDM, and the other part (such as PSS or SSS) can be transmitted using CP-OFDM. The SSB can be transmitted in the form of FDM or discrete frequency domain, or not in the form of FDM or discrete frequency domain.

[0202] Optionally, as an embodiment, when transmitting at least two transmission objects, the terminal may use DFT-s-OFDM to transmit at least two transmission objects, or, when at least two transmission objects are continuous in the frequency domain or the frequency domain interval is less than a preset value, use DFT-s-OFDM to transmit at least two transmission objects.

[0203] In an embodiment of the present application, when a terminal sends or receives (a network-side device receives or sends) multiple transmission objects in the form of FDM or discrete frequency domain, the same or different transmission methods may be used for one or at least two transmission objects, and when transmitting in the same or different methods, the same or different waveforms, initialization parameters, scrambling methods, sequences, phases, or rotation phases may be used for transmission. Thus, in a scenario where multiple transmission objects are transmitted in the form of FDM or discrete frequency domain, the terminal and the network-side device can select an appropriate transmission method for transmission, thereby reducing PAPR and ensuring coverage.

[0204] As shown in FIG3 , an embodiment of the present application provides a transmission method 300 , which can be executed by a network-side device. In other words, the transmission method can be executed by software or hardware installed in the network-side device. The transmission method includes the following steps.

[0205] S302: The network side device determines a transmission mode of one or at least two transmission objects, where the transmission mode includes transmission using the same or different modes, or the transmission mode is related to at least one of the waveform, initialization parameter, scrambling mode, sequence, phase or rotation phase used when transmission using the same or different modes, and the transmission object includes a signal or a channel or a part of a signal or a part of a channel, and at least two transmission objects are transmitted in the form of FDM or discrete frequency domain.

[0206] S304: The network-side device transmits one or at least two transmission objects according to the transmission mode.

[0207] When the network side device transmits (receives or sends) multiple transmission objects in the form of FDM or discrete frequency domain, it can determine the transmission mode (receiving mode or sending mode) for one or at least two transmission objects, and then transmit one or at least two transmission objects using the determined transmission mode.

[0208] The at least two transmission objects mentioned above can be part of the transmission objects among the multiple transmission objects, or can be all of the multiple transmission objects, which is not specifically limited here. For each transmission object, the transmission object can be a signal or a channel or a part of a signal or a part of a channel.

For example, different waveforms may correspond to different CORESET resources or Search Space or PDCCH MOs at specific time-frequency domain locations.

[0252] The SIB may be at least one of SIB1, RMSI, other SIBs, OSI, 6G, or system information in any future mobile communication system. When the first information includes the SIB, the first information indicates the transmission mode, which may be a signaling indicating the transmission mode carried by one or more bits in the SIB. For example, a signaling indicating the transmission mode carried by one or more bits in SIB1 or OSI.

[0275] For explanations of the various factors included in the at least one factor, please refer to the corresponding descriptions of these factors when the terminal determines the transmission mode according to the implicit method in the embodiment shown in FIG2 , and will not be repeated here.

[0276] Optionally, the correspondence between the above at least one factor and the transmission mode can be configured or indicated by the network side device through MAC CE or RRC.

[0277] Optionally, in some embodiments, the network side device may also receive capability information of the terminal. In this way, the network side device can better determine how to transmit (receive or send) at least two transmission objects based on the capability information of the terminal. The capability information of the terminal may include at least one of the following:

[0278] Supporting or using the same method to transmit the at least two transmission objects;

[0279] Supporting or using different ways to transmit the at least two transmission objects;

[0280] Support (using the same or different methods) at least one of the waveform, initialization parameters, scrambling method, sequence, phase or rotation phase used during transmission.

[0281] Optionally, in some implementations, the network side device may also transmit at least two transmission objects in the form of FDM or discrete frequency domain before entering the RRC connected state. In this case, the network side device determines the transmission mode of the at least two transmission objects, which may include at least one of the following:

[0282] Determine the transmission mode according to second information, the second information including frequency band, sub-band, frequency band combination, frequency range, scenario, purpose of the at least two transmission objects, type of the at least two transmission objects, attribute information corresponding to the at least two transmission objects, moving speed of the terminal, time information, frequency domain information, the interval between the at least two transmission objects, spectrum deployment mode, output power or transmit power, configuration of random access channel, resources of random access channel, preamble format, time domain configuration, frequency domain configuration, whether transmission on one or more channels, carriers, partial bandwidth or cells is repeated or the number of repetitions, the number of transmission objects, and at least one of multiple access modes, and the second information has a corresponding relationship with the transmission mode;

[0283] Use different transmission modes at different frequency domain locations; for example, SSB of multiple transmission modes is transmitted at different frequency domain locations (such as different sync rasters or sync raster + offset locations);

[0284] Use different transmission modes at different time domain locations; for example, SSB with multiple transmission modes is sent at different time domain locations.

[0285] The transmission mode is determined to be a transmission mode in a specified mode; for example, SSB of multiple transmission modes is transmitted in a certain pattern;

[0286] The transmission mode is determined to be a transmission at a specific location or time; for example, SSB of multiple transmission modes is transmitted at a specific location or time.

[0287] After the network side device enters the RRC connection state, for subsequent transmission objects, the network side device can determine the transmission mode according to the implicit method described above, or indicate the transmission mode to the terminal through the first information. Optionally, as an embodiment, taking the transmission object as SSB in 5G (which can also be called any module containing at least one of synchronization signal, broadcast signal, broadcast channel (PBCH), and other system message downlink broadcast channel) as an example, the terminal uses the default transmission mode to receive SSB, and the SSB carries the transmission mode indication information of the subsequent transmission object. The indication information can be a few bits explicitly carried in the MIB, or indicated by a specific value (such as a specific value indicated by the subcarrier offset parameter of the SSB and the reference grid or reference point). After receiving the SSB, the terminal can obtain the transmission mode indication information of the subsequent transmission object (such as SIB1), and then the terminal can use the transmission mode determined in the transmission mode indication information to transmit the subsequent transmission object. The transmission mode indication information in the SSB may indicate only the transmission mode of the next transmission object, or the transmission modes of the subsequent N transmission objects, or the transmission modes of the subsequent one or more downlink transmission objects, or the transmission modes of the subsequent one or more uplink transmission objects. Optionally, if the transmission mode indication information in the SSB indicates only the transmission mode of the next transmission object (such as SIB1), then the transmission modes of the transmission objects after SIB1 may be indicated in SIB1.

[0288] Optionally, in some implementations, the network-side device determines the transmission mode of at least two transmission objects, and may further include:

[0289] The network side device determines the transmission mode according to the transmission capability or the related capability of the transmission capability supported by the network side device, and the transmission capability or the related capability of the transmission capability has a corresponding relationship with the transmission mode.

[0290] The transmission capability may include at least one of the following: supporting or using the same method to transmit at least two transmission objects; supporting or using different methods to transmit at least two transmission objects; supporting or using different methods to transmit at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when transmitting at least two transmission objects. When determining the transmission object based on the transmission capability, for example, if the network-side device has the ability to receive a phase-rotated transmission object (e.g., SSB), then when sending multiple transmission objects, the network-side device may send the phase-rotated transmission object, or the terminal may detect the phase-rotated transmission object. For another example, if the network-side device has the ability to simultaneously search for or detect transmission objects (e.g., SSB) generated using different initialization parameters, then when receiving multiple transmission objects, the network-side device may receive transmission objects generated using different initialization parameters, or the terminal may send transmission objects generated using different initialization parameters.

[0291] The relevant capabilities of the transmission capability can be, for example, the scenarios supported by the network-side device (such as TN or NTN). There is a corresponding relationship between the relevant capabilities of the transmission capability and the transmission mode. For example, the network-side device can support operation in both TN and NTN scenarios. In this case, the transmission objects of different scenarios may be generated using different methods, so that the network-side device can receive or send at least two transmission objects generated using different methods, or the terminal can send or receive at least two transmission objects generated using different methods.

[0292] Optionally, in some implementations, when the network side device transmits at least one transmission object, the following steps may be further included:

[0293] When at least one of the at least one transmission object includes at least a first part and a second part, the first part is transmitted using DFT-s-OFDM and the second part is transmitted using CP-OFDM.

[0294] The at least one transmission object here may be one or more of the at least two transmission objects in S302, in which case the at least one transmission object is transmitted in FDM or discrete frequency domain format. Alternatively, the at least one transmission object may be another transmission object other than the at least two transmission objects in S302, in which case the at least one transmission object is not required to be transmitted in FDM or discrete frequency domain format.

[0295] For example, for an SSB, when the network-side device transmits the SSB, part of the SSB (such as PBCH or PBCH DMRS) can be transmitted using DFT-s-OFDM, and the other part (such as PSS or SSS) can be transmitted using CP-OFDM. The SSB may be transmitted in the form of FDM or discrete frequency domain, or may not be transmitted in the form of FDM or discrete frequency domain.

[0296] Optionally, as an embodiment, when the network side device transmits at least two transmission objects, it may use DFT-s-OFDM to transmit at least two transmission objects, or, when at least two transmission objects are continuous in the frequency domain or the frequency domain interval is less than a preset value, use DFT-s-OFDM to transmit at least two transmission objects.

[0297] In an embodiment of the present application, when a network-side device sends or receives (a terminal receives or sends in the form of FDM or discrete frequency domain) multiple transmission objects in the form of FDM or discrete frequency domain, the same or different transmission methods may be used for one or at least two transmission objects, and when transmitting in the same or different methods, the same or different waveforms, initialization parameters, scrambling methods, sequences, phases, or rotation phases may be used for transmission. Thus, in a scenario where multiple transmission objects are transmitted in the form of FDM or discrete frequency domain, the terminal and the network-side device can select an appropriate transmission method for transmission, thereby reducing PAPR and ensuring coverage.

[0298] The transmission method provided in the embodiment of the present application can be executed by a transmission device. In the embodiment of the present application, the transmission device provided in the embodiment of the present application is described by taking the transmission method executed by the transmission device as an example.
