[0002] When a network-side device communicates with a terminal, it can send or receive multiple transmission objects in the form of frequency-division multiplexing (FDM) or discrete frequency domain.

[0035] Next, with reference to the accompanying drawings, the transmission method, terminal, and network-side device provided by the embodiments of this application will be described in detail through some embodiments and their application scenarios.
[0036] As Figure 2 shown, the embodiments of this application provide a transmission method 200. This method can be executed by a terminal. In other words, this transmission method can be executed by software or hardware installed in the terminal. The transmission method includes the following steps.
[0037] S202: The terminal determines the transmission mode of one or at least two transmission objects. The transmission mode includes transmitting using the same or different methods, or the transmission mode is related to at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when transmitting using the same or different methods. The transmission objects include signals or channels or parts of signals or parts of channels. At least two transmission objects are transmitted in the form of frequency division multiplexing (FDM) or discrete frequency domain.
[0038] S204: The terminal transmits one or at least two transmission objects according to the transmission mode.
[0039] When a terminal transmits (sends or receives) multiple transmission objects in the form of FDM or discrete frequency domain, for one or at least two of the transmission objects, the transmission mode (transmission mode or reception mode) of one or at least two transmission objects can be determined, and then one or at least two transmission objects are transmitted in the determined transmission mode.
[0040] The above at least two transmission objects can be some of the multiple transmission objects or all of the multiple transmission objects, and no specific limitation is made 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. Correspondingly, the at least two transmission objects can be at least two signals or at least two channels or at least two parts of signals or at least two parts of channels, or can also be any combination of at least one signal, at least one channel, at least one part of a signal, and at least one part of a 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 a signal and a part of a channel, or a part of a 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 no further examples are given here.
[0041] Optionally, in some embodiments, the transmission object may include but is not limited to at least one of the following:
[0042] Synchronization signal; broadcast signal; Synchronization Signal and PBCH block (SSB); Master Information Block (MIB); Random Access CHannel occasion (RO); Paging Occasion (PO); Paging frame (PF); Physical Uplink Shared CHannel (PUSCH) occasion; carrier; SearchSpace set.
[0043] Optionally, the at least two object transmission objects can be the same type of signal. For example, they are all synchronization signals or broadcast channels, such as all PUCCHs, etc.
[0044] The transmission mode of one transmission object can include at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when transmitting the object.
[0045] The transmission method for at least two transmission objects can be to transmit at least two transmission objects using the same method, or to transmit at least two transmission objects using different methods, or at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when transmitting at least two transmission objects using the same method, or at least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when transmitting at least two transmission objects using different methods. In this way, when the terminal transmits at least two transmission objects, it can select an appropriate method for transmission, thereby reducing the PAPR and ensuring coverage.
[0046] In the case of transmitting at least two transmission objects using different methods, optionally, in some embodiments, the use of different methods for transmission may satisfy at least one of the following:
[0047] At least two transmission objects use different waveforms;
[0048] At least two transmission objects are generated based on different initialization parameters;
[0049] At least two transmission objects use different scrambling methods;
[0050] At least two transmission objects use different sequences;
[0051] At least two transmission objects use different phases or phase rotations.
[0052] The above waveforms may include, but are not limited to, at least one of multi-carrier waveforms, single-carrier waveforms, Orthogonal Time Frequency Space (OTFS) waveforms, low-power waveforms, Chirp waveforms, Frequency Modulated Continuous Wave (FMCW) waveforms, Linear Frequency Modulation (LFM) waveforms, amplitude modulation waveforms, frequency modulation waveforms, and phase modulation waveforms. Among them, the multi-carrier waveform can be, for example, Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), Filter-bank multicarrier (FBMC), Generalized Frequency Division Multiplexing (GFDM), Universal Filtered Multi Carrier (UFMC), Filter-Orthogonal Frequency Division Multiplexing (F-OFDM), etc. The single-carrier waveform can be, for example, Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-s-OFDM), constant envelope waveform, Single Carrier Frequency Domain Equalization (SC-FDE), etc. The OTFS waveform is mainly for high speed or large payload. The low-power waveform can be, for example, Ultra Wide band (UWB).
[0053] At least two transmission objects are generated based on different initialization parameters, such as being generated based on different N_ID1, N_ID2, Physical Cell Identifier (PCI), or Index.
[0054] At least two transmission objects use different scrambling methods, such as being scrambled using different scrambling sequences.
[0055] At least two transmission objects use different sequences, for example, different types of sequences can be used (such as golden sequences, m sequences, zc sequences), or, alternatively, the types of sequences used are the same but the sequences are different.
[0056] When determining the transmission methods of at least two transmission objects, the terminal can be determined by at least one of an implicit method and an explicit method. The implicit method can be that the terminal determines the transmission method according to the relevant information when transmitting at least two transmission objects and the corresponding relationship between the relevant information and the transmission method. The explicit method can be that the terminal determines the transmission method according to the indication of the network-side device. Among them, the transmission method determined according to the implicit method or the explicit method can be to use the same or different methods to transmit at least two transmission objects, or, at least one of the waveform, initialization parameter, scrambling method, sequence, phase or rotation phase used when using the same or different methods to transmit at least two transmission objects.
[0057] Optionally, in some embodiments, in the case of determining the transmission method by an implicit method, the terminal determines the transmission method of at least two transmission objects, which may include at least one of the following (1) to (15):
[0058] (1) Determine the transmission method according to the frequency band (Band), sub-band (subband), frequency band combination (bandCombination) or frequency range (Frequency Range, FR).
[0059] There is a corresponding relationship between the frequency band, sub-band, frequency band combination or frequency range and the transmission method. In some embodiments, there is a predefined corresponding relationship between different bands or sub-bands or bandCombinations or FRs and using the same or different methods for transmission. For example, when operating in the millimeter-wave frequency band, at least two transmission objects can be transmitted using different methods (at least one of different waveforms, different initialization parameters, different scrambling sequences, different signal sequences, different phases, different phase rotations), and when operating in FR1 or the low-frequency band (such as 1 GHz), at least two transmission objects can be transmitted using the same method (at least one of the same waveform, the same initialization parameter, the same scrambling sequence, the same signal sequence, the same phase, the same phase rotation). Or, alternatively, it can be that when operating in the millimeter-wave frequency band, at least two transmission objects are transmitted using the same method, and when operating in FR1 or the low-frequency band (such as 1 GHz), at least two transmission objects are transmitted using different methods.
[0060] In some embodiments, there is a predefined correspondence between different bands or subbands or band Combinations or FRs and at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase used for transmission. For example, when operating in the FR2-2 or FR2-3 frequency bands, at least two transmission objects can perform phase rotation 1 or phase rotation 2 respectively, and when operating in the FR2-1 frequency band, at least two transmission objects can perform phase rotation 3 or phase rotation 4 respectively. Alternatively, it can also be that when operating in the FR2-2 or FR2-3 frequency bands, at least two transmission objects can perform phase rotation 3 or phase rotation 4 respectively, and when operating in the FR2-1 frequency band, at least two transmission objects can perform phase rotation 1 or phase rotation 2 respectively.
[0061] In some embodiments, each band or subband or band Combination or FR can be associated with multiple transmission methods (such as using different methods for transmission, using the same method for transmission, at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase when using different methods for transmission, and at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase when using the same method for transmission), and which specific transmission method to adopt can be further determined according to other factors (such as the type of base station, etc.).
[0062] For example, on a certain band, subband, band combination, 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 (such as a maximum transmit power of only 24 dBm), and also support some global base stations or ordinary base stations with relatively strong capabilities (such as a maximum transmit power of 38 dBm or even unlimited). Although the two types of base stations operate on the same band, subband, band combination, or FR, the transmission methods used may be different. When determining the transmission method, for example, if the base station type is a local base station, at least two transmission objects can be transmitted using different methods; if the base station type is a global base station or an ordinary base station, at least two transmission objects can be transmitted using the same method. Further, for each base station type, when transmitting at least two transmission objects, there is a corresponding relationship between at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase used and the band, subband, band combination, or FR. That is to say, when the terminal determines the transmission method, it can first determine whether to use the same or different methods for transmission according to the base station type, and then determine at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase used during transmission according to the band, subband, band combination, or FR.
[0063] (2) Determine the transmission method according to the scenario or the use of at least two transmission objects.
[0064] There is a corresponding relationship between the scenario or use and the transmission method. The scenario can be, for example, a terrestrial network (TN), a non-terrestrial network (NTN), etc. The use of at least two transmission objects can be, for example, for cell search, for assisting in determining the timing advance (TA), for validation, for TA validation, for beam management (BM), measurement, persistent objects, or forced transmission objects, on-demand triggered objects, or on-demand transmitted objects, etc.
[0065] Taking the transmission mode of at least two transmission objects determined according to the scenario as an example, for instance, the same mode can be used to transmit at least two transmission objects in the TN scenario, and different modes can be used to transmit at least two transmission objects in the NTN scenario. Or, it can also be that different modes are used to transmit at least two transmission objects in the TN scenario, and the same mode is used to transmit at least two transmission objects in the NTN scenario.
[0066] (3) Determine the transmission mode according to the type information of at least two transmission objects or the attribute information corresponding to at least two transmission objects.
[0067] There is a corresponding relationship between the type information or attribute information of at least two transmission objects and the transmission mode.
[0068] The type information of at least two transmission objects may include, but is not limited to, at least one of the following:
[0069] The destinations corresponding to at least two transmission objects (such as for cell search, for assisting in determining Timing Advance (TA), for validation, for TA validation, for beam management (BM), measurement, persistent objects, or objects for forced transmission (forced transmission can also be interpreted as inevitable transmission, or necessarily needs to be considered), on-demand triggered objects, or on-demand transmitted objects, etc.); specifically, transmission can be interpreted as sending or receiving;
[0070] The terminal types corresponding to at least two transmission objects (such as Reduced Capability (RedCap) terminals, smart phones, different types of IoT devices, different types of Ambient Internet of Things (A-IoT) devices, terminals with different power levels, different cyclic prefix extension (CPE) durations);
[0071] The network types corresponding to at least two transmission objects (such as Terrestrial Network (TN), Non Terrestrial Network (NTN), IoT network, non-IoT network);
[0072] The synchronization signal types corresponding to at least two transmission objects;
[0073] The broadcast signal types corresponding to at least two transmission objects;
[0074] The Band Width Part (BWP) corresponding to at least two transmission objects;
[0075] Time-frequency resource blocks corresponding to at least two transmission objects;
[0076] Duplex modes (such as full duplex, half duplex, etc.) corresponding to at least two transmission objects;
[0077] Access methods or access approaches corresponding to at least two transmission objects;
[0078] Cells (such as macro cells, small cells) corresponding to at least two transmission objects;
[0079] Types of Transmission Reception Points (TRPs) (such as multi-TRP (MTRP), single-TRP) corresponding to at least two transmission objects;
[0080] Waveforms (such as 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) corresponding to at least two transmission objects;
[0081] RAN services (such as sensing services, NTN services, low-power synchronization signal (LP-SS) services, wake-up signal (WUS) services) corresponding to at least two transmission objects;
[0082] Network energy-saving characteristics (such as related to the long and short periods of SSB, or whether paging, System Information Block (SIB), Random Access Channel (RACH), etc. are enabled, the periods of paging or SIB or RACH, etc.) corresponding to at least two transmission objects;
[0083] SSB periods corresponding to at least two transmission objects;
[0084] Measurement periods corresponding to at least two transmission objects;
[0085] Other relevant signal periods corresponding to at least two transmission objects (such as the periods of paging, SIB, or RACH);
[0086] Higher-layer protocol characteristics corresponding to at least two transmission objects (for example, whether the higher-layer protocol enables special services, such as the data plane, NPN, or a simplified protocol stack, etc.).
[0087] The attribute information of at least two transmission objects includes but is not limited to at least one of the following:
[0088] 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 characteristic information, period information, higher-layer characteristic information, transmission information, destination information, terminal information, network information.
[0089] Exemplarily, the above-mentioned transmission information may include at least one of the following:
[0090] Whether to transmit the transmission object multiple times in the time domain, whether multiple transmission objects are included within the transmission time window of the transmission object, whether to transmit the transmission object multiple times in the frequency domain, whether multiple transmission objects are included within a specific bandwidth, whether to use continuous time-domain transmission for the transmission object, whether to use continuous frequency-domain transmission for the transmission object (for example, if transmitting multiple times in the frequency domain, whether it is transmitted on continuous resources and whether there are intervals), whether to use discrete time-domain resources to transmit the transmission object (such as using interlace transmission), whether to use discrete frequency-domain resources to transmit the transmission object (such as using interlace transmission), whether to transmit the reference signal sequence corresponding to the transmission object multiple times in the time domain, whether multiple reference signal sequences corresponding to the transmission object are included within the transmission time window of the transmission object, whether to transmit the reference signal sequence corresponding to the transmission object multiple times in the frequency domain, whether multiple reference signal sequences corresponding to the transmission object are included within a specific bandwidth, whether to use continuous time-domain transmission for the reference signal sequence corresponding to the transmission object, whether to use continuous frequency-domain transmission for the reference signal sequence corresponding to the transmission object (for example, if transmitting multiple times in the frequency domain, whether it is transmitted on continuous resources and whether there are intervals), whether to use discrete time-domain resources to transmit the reference signal sequence corresponding to the transmission object (such as using interlace transmission), whether to use discrete frequency-domain resources to transmit the reference signal sequence corresponding to the transmission object (such as using interlace transmission).
[0091] In some embodiments, there is a predefined correspondence between different types of information or attribute information and the use of the same or different transmission 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, 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 waveforms, the same initialization parameters, the same scrambling sequences, the same signal sequences, the same phases, the same phase rotations). Alternatively, it may also be that at least two transmission objects corresponding to type 1 are transmitted using the same method, and at least two transmission objects corresponding to type 2 are transmitted using different methods.
[0092] In some embodiments, there is a predefined correspondence between different types or attribute information and at least one of the waveform, initialization parameters, scrambling method, sequence, phase, or rotation phase used for transmission. For example, at least two transmission objects corresponding to type 1 are respectively subjected to phase rotation 1 or phase rotation 2, and at least two transmission objects corresponding to type 2 are respectively subjected to phase rotation 3 or phase rotation 4.
[0093] (4) Determine the transmission method according to the moving speed of the terminal.
[0094] There is a correspondence between the moving speed and the transmission method. In some embodiments, there is a predefined correspondence between the moving speed and the use of the same or different transmission methods, or there may also be a predefined correspondence between the moving speed and at least one of the waveform, initialization parameters, scrambling method, 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 methods of at least two transmission objects according to the correspondence between the moving speed and the transmission method. For the network-side device, it can obtain the moving speed of the terminal 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 according to the information reported by the terminal, and then determine the transmission methods of at least two transmission objects based on the correspondence between the moving speed and the transmission method.
[0095] For example, when the moving speed of the terminal does not exceed X km / h, at least two transmission objects are transmitted in the same way. When the moving speed of the terminal is less than X km / h, at least two transmission objects are transmitted in different ways. Or, it can also be that when the moving speed of the terminal does not exceed X km / h, at least two transmission objects are transmitted in different ways.

For example, when the bandwidth is greater than M1, at least two transmission objects are transmitted in different ways. When the bandwidth is less than M1, at least two transmission objects are transmitted in the same way. Or, it can also be that when the bandwidth is greater than M1, at least two transmission objects are transmitted in the same way.

When the interval between at least two transmission objects is less than M2, the transmission mode of at least two transmission objects is to use the same transmission mode. Alternatively, it can also be that when the interval between at least two transmission objects is greater than M2, the transmission mode of at least two transmission objects is to use the same transmission mode.

Optionally, in some embodiments, there is a predefined corresponding relationship between whether the transmission on one or more channels, carriers, partial bandwidths, or cells is repeated and the transmission using the same or different methods. For example, if the transmission on the cell is repeated, the transmission modes of at least two transmission objects are to use the same method for transmission; if the transmission on the cell is not repeated, the transmission modes of at least two transmission objects are to use different methods for transmission.

Optionally, in some embodiments, there is a predefined corresponding relationship between the number of repetitions of the transmission on one or more channels, carriers, partial bandwidths, or cells and the transmissions using the same or different modes. For example, if the number of repetitions of the transmission on a cell is greater than a certain value, the transmission modes of at least two transmission objects are the same; if the number of repetitions of the transmission on a cell is less than a certain value, the transmission modes of at least two transmission objects are different.

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 different; if the number of transmission objects transmitted in the FDM mode exceeds N, the transmission modes of at least two transmission objects are the same. Or, it can also 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 the same, and if the number of transmission objects transmitted in the FDM mode exceeds N, the transmission modes of at least two transmission objects are different.

[0122] 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 the transmissions using the same or different modes. For example, if the non-orthogonal multiple access mode (such as multi-user multiple input-multiple output (MU-MIMO)) is used, the transmission modes of at least two transmission objects are the same; if the non-orthogonal multiple access mode is not used, the transmission modes of at least two transmission objects are different.

For example, one or more bits of signaling carried in SIB1 or OSI indicate the transmission mode. When the terminal determines the transmission modes of at least two transmission objects according to the SIB, it can determine the corresponding transmission mode according to the indication of the signaling in the SIB.
[0144] The common message or channel can be a message or channel that can be received by multiple terminals.

When the first information includes a DCI or PDCCH, the first indication information indicates the transmission mode, which may include at least one of the following:
[0152] Carry the transmission mode through the information bits or fields in the DCI or PDCCH.

[0156] When the first information includes a signal or channel scrambled by a specific RNTI, or when the first information includes a specific RNTI, the specific RNTI is determined by at least one of the following methods:
[0157] Configure or indicate a specific RNTI. For example, the base station configures or indicates a specific RNTI;

When the terminal determines the transmission mode for at least two transmission objects based on a signal or channel scrambled by a specific RNTI, or a specific RNTI, it may determine the corresponding transmission mode according to the indication of the specific RNTI, or determine the corresponding transmission mode according to the offset based on which the specific RNTI is determined or generated and the corresponding relationship between the offset and the transmission mode.

[0168] For the explanations of the various factors included in the above at least one factor, reference can be made to the corresponding descriptions of these factors when the above terminal determines the transmission mode according to the implicit method, and no repeated description will be given here.
[0169] Optionally, the correspondence between the above at least one factor and the transmission mode can be configured or indicated by MAC CE or RRC. When the terminal determines the transmission mode for at least two transmission objects according to MAC-CE or RRC, it can be determined according to the correspondence between 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 through RRC, then when the terminal operates in the FR1 frequency band, it 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, it can use the transmission mode corresponding to the FR2 frequency band to transmit at least two transmission objects. Another example is that the network-side device configures the transmission modes corresponding to the case where the terminal's moving speed is less than 250 km / h and the case where the terminal's moving speed is greater than 250 km / h respectively through 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.
[0170] Optionally, in some embodiments, the terminal can also send its own capability information. For example, the terminal can send its own capability information to the network-side device. When the network-side device receives the capability information of the terminal, it can better determine how to transmit (receive or send) at least two transmission objects according to this capability information. Among them, the capability information of the terminal can include at least one of the following:
[0171] Support or use the same method to transmit at least two transmission objects;
[0172] Support or use different methods for at least two transmission objects;
[0173] At least one of the waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when supporting (using the same or different methods) for transmission.
[0174] Optionally, in some embodiments, before entering the RRC connected state, the terminal can also transmit at least two transmission objects in the form of FDM or discrete frequency domain. In this case, the terminal's determination of the transmission mode for at least two transmission objects can include at least one of the following:
[0175] Determine the transmission mode according to the 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, the uses of at least two transmission objects, the types 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 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, one or more channels, carriers, whether the transmission on a partial bandwidth or a cell is repeated or the number of repetitions, the number of transmission objects, and the multiple access mode. There is a corresponding relationship between the second information and the transmission mode;
[0176] Use different transmission modes at different frequency domain positions;
[0177] Use different transmission modes at different time domain positions;
[0178] Determine the transmission as the transmission mode in a specified mode;
[0179] Determine the transmission at a specific position or time as the transmission mode.
[0180] For the explanatory notes of each item of the above second information, reference can be made to the corresponding descriptions of this information when the terminal determines the transmission mode according to the implicit method, and the description will not be repeated here.
[0181] As an embodiment, taking the transmission object as the SSB in 5G (which can also be called any module including at least one of a synchronization signal, a broadcast signal, a physical broadcast channel (PBCH), and a downlink broadcast channel for other system messages) as an example, there can be multiple transmission modes for the first or the first N SSBs before the terminal enters the RRC connected state. In this case, it is impossible for the network-side device (such as a base station) to send any indication information about the transmission mode to the terminal in advance. Then, the terminal can use the following several methods to determine the transmission mode of the first SSB before entering the RRC connected state:
[0182] The first method: There is a one-to-one correspondence between the method used for SSB transmission and the second information.
[0183] When a base station or a terminal transmits an SSB, it can select a corresponding transmission mode for transmission on different second information. The second information includes at least one of frequency band, sub - frequency band, frequency band combination, frequency range, scenario, uses of at least two transmission objects, types of at least two transmission objects, attribute information corresponding to at least two transmission objects, moving speed of the terminal, time information, frequency domain information, interval between at least two transmission objects, deployment mode of the spectrum, output power or transmission power, configuration of the random access channel, resources of the random access channel, preamble format, time domain configuration, frequency domain configuration, one or more channels, carrier, whether transmission on a partial bandwidth or a cell is repeated or the number of repetitions, number of transmission objects, and multiple access mode.
[0184] The second method: SSBs with multiple transmission modes are transmitted separately at different frequency domain positions (such as on different sync.raster or at sync raster + offset positions).
[0185] The terminal can perform blind detection separately using multiple transmission modes at different sync.raster or sync raster + offset positions. Optionally, the frequency domain positions of multiple transmissions of the SBB with the same transmission mode are fixed.
[0186] The second method: SSBs with multiple transmission modes are sent separately at different time domain positions.
[0187] The terminal can perform blind detection separately using multiple transmission modes at different time domain positions. Optionally, the time domain positions of multiple transmissions of the SSB with the same transmission mode are periodic.
[0188] The third method: SSBs with multiple transmission modes are transmitted in a certain pattern.
[0189] For example, there is co - existence of OTFS frame and OFDM frame in a TDM or CDM manner.
[0190] The fourth method: SSBs with multiple transmission modes are sent at specific positions or moments.
[0191] After the terminal enters the RRC connected state, for subsequent transmission objects, when the terminal transmits, it can determine the transmission mode according to the implicit method or explicit method described above. Optionally, as an embodiment, the terminal uses the default transmission mode to receive the SSB, and the SSB carries the transmission mode indication information of the subsequent transmission object. Among them, the indication information can be several 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), etc. 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. Among them, the transmission mode indication information in the SSB can 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 only indicates the transmission mode of the next transmission object (such as SIB1), then the transmission mode of the transmission object after SIB1 can be indicated in SIB1.
[0192] Optionally, in some embodiments, when the terminal determines the transmission modes of at least two transmission objects, it may further include:
[0193] The terminal determines the transmission mode according to the transmission capabilities supported by the terminal or the related capabilities of the transmission capabilities, and there is a corresponding relationship between the transmission capabilities or the related capabilities of the transmission capabilities and the transmission mode.
[0194] The transmission capabilities may include at least one of the following: supporting or using the same mode to transmit at least two transmission objects; supporting or using different modes to transmit at least two transmission objects; at least one of the waveform, initialization parameter, scrambling mode, sequence, phase, or rotation phase used when supporting or using different modes to transmit at least two transmission objects. When determining the transmission object according to the transmission capabilities, for example, if the terminal has the ability to receive a transmission object (such as an SSB) with phase rotation, then when the terminal receives multiple transmission objects, it can detect the transmission object with phase rotation, or the base station can send a transmission object with phase rotation. Another example is that if the terminal has the ability to search or detect transmission objects (such as SSBs) generated using different initialization parameters at the same time, then when the terminal receives multiple transmission objects, it can receive transmission objects generated using different initialization parameters, or the base station can send transmission objects generated using different initialization parameters.
[0195] The related capabilities of the transmission capability may be, for example, the scenarios supported by the terminal (such as TN or NTN). There is a corresponding relationship between the related capabilities of the transmission capability and the transmission mode. For example, the terminal can support working in both TN and NTN scenarios simultaneously. In this case, the transmission objects in 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.
[0196] Optionally, in some embodiments, when the terminal transmits at least one transmission object, it may further include:
[0197] When at least one of the at least one transmission object includes at least a first part and a second part, DFT-s-OFDM is used to transmit the first part, and CP-OFDM is used to transmit the second part.
[0198] The at least one transmission object here may be one or more of the at least two transmission objects in S202. At this time, 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 also be other transmission objects other than the at least two transmission objects in S202. At this time, the at least one transmission object is not required to be transmitted in the form of FDM or discrete frequency domain.
[0199] For example, for an SSB, when the terminal transmits the SSB, a part of the SSB (such as PBCH or PBCH DMRS) can be transmitted using DFT-s-OFDM, and another part (such as PSS or SSS) can be transmitted using CP-OFDM. Among them, the one SSB can be transmitted in the form of FDM or discrete frequency domain, or not in the form of FDM or discrete frequency domain.
[0200] Optionally, as an embodiment, when the terminal transmits at least two transmission objects, DFT-s-OFDM can be used to transmit the at least two transmission objects, or when the at least two transmission objects are frequency-continuous or the frequency interval is less than a preset value, DFT-s-OFDM is used to transmit the at least two transmission objects.
[0201] In an embodiment of the present application, when the terminal sends or receives (the network-side device receives or sends) multiple transmission objects in the form of FDM or discrete frequency domain, for one or at least two of the transmission objects, the same or different transmission methods can be used, and when using the same or different transmission methods, at least one of the same or different waveforms, initialization parameters, scrambling methods, sequences, phases, or rotation phases can be used for transmission. Thus, in the scenario of transmitting multiple transmission objects 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 the PAPR and ensuring coverage.
[0202] As Figure 3 shown, an embodiment of the present application provides a transmission method 300. This method can be executed by a network-side device. In other words, this transmission method can be executed by software or hardware installed in the network-side device. The transmission method includes the following steps.
[0203] S302: The network-side device determines the transmission method for one or at least two transmission objects. The transmission method includes using the same or different methods for transmission, or the transmission method is related to at least one of the waveforms, initialization parameters, scrambling methods, sequences, phases, or rotation phases used when using the same or different methods for transmission. The transmission objects include signals or channels or parts of signals or parts of channels. At least two transmission objects are transmitted in the form of FDM or discrete frequency domain.
[0204] S304: The network-side device transmits one or at least two transmission objects according to the transmission method.
[0205] When the network-side device transmits (receives or sends) multiple transmission objects in the form of FDM or discrete frequency domain, for one or at least two of the transmission objects, it can determine the transmission method (receiving method or sending method) for one or at least two transmission objects, and then transmit one or at least two transmission objects according to the determined transmission method.
[0206] The above at least two transmission objects may be some of the multiple transmission objects or all of the multiple transmission objects, and no specific limitation is made here. For each transmission object, the transmission object may be a signal or a channel or a part of a signal or a part of a channel. Correspondingly, the at least two transmission objects may be at least two signals or at least two channels or at least two parts of signals or at least two parts of channels, or may also be any combination of at least one signal, at least one channel, at least one part of a signal, and at least one part of a channel. For example, the at least two transmission objects may be two signals, or two channels, or two parts of one signal, or two parts of one 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 one signal and a part of another signal, or one channel and a part of another channel, etc., and no further examples are given here.

In this way, when the network-side device transmits at least two transmission objects, it can select an appropriate mode for transmission, thereby reducing PAPR and ensuring coverage.
[0212] In the case of transmitting at least two transmission objects using different modes, optionally, in some embodiments, the use of different modes for transmission may satisfy at least one of the following:
[0213] At least two transmission objects use different waveforms; the waveforms may include but are not limited to at least one of multi-carrier waveforms, single-carrier waveforms, OTFS waveforms, low-power waveforms, Chirp waveforms, FMCW waveforms, LFM waveforms, amplitude-modulated waveforms, frequency-modulated waveforms, and phase-modulated waveforms; the multi-carrier waveforms may be, for example, CP-OFDM, FBMC, GFDM, UFMC, F-OFDM, etc.; the single-carrier waveforms may be, for example, DFT-s-OFDM, constant envelope waveforms, single-carrier frequency-domain equalization SC-FDE, etc.; the OTFS waveform is mainly for high speed or large payload; the low-power waveform may be, for example, UWB;

[0217] At least two transmission objects use different phases or phase rotations.
[0218] When determining the transmission methods of at least two transmission objects, the network-side device may determine them through an implicit method. The implicit method may be that the network-side device determines the transmission method according to the relevant information when transmitting at least two transmission objects and the corresponding relationship between the relevant information and the transmission method. Among them, the transmission method determined according to the implicit method may be to transmit at least two transmission objects using the same or different methods, or, to use the same or different methods for at least one of the waveforms, initialization parameters, scrambling methods, sequences, phases, or rotation phases when transmitting at least two transmission objects.

[0273] For the explanatory descriptions of the various factors included in the above at least one factor, reference may be made to Figure 2 The corresponding descriptions of these factors when the terminal determines the transmission mode according to the implicit method in the illustrated embodiments are not repeated here.
[0274] Optionally, the corresponding relationship between the above at least one factor and the transmission mode may be configured or indicated by the network-side device through MAC CE or RRC.
[0275] Optionally, in some embodiments, the network-side device may also receive the 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 according to the capability information of the terminal. Among them, the capability information of the terminal may include at least one of the following:

[0279] Optionally, in some embodiments, before entering the RRC connected state, the network-side device may also transmit the at least two transmission objects in the form of FDM or discrete frequency domain. In this case, the network-side device determines the transmission method of the at least two transmission objects, which may include at least one of the following:
[0280] Determine the transmission method according to the second information, where the second information includes at least one of frequency band, sub-band, frequency band combination, frequency range, scenario, use 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, interval between the 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, one or more channels, carrier, whether transmission on partial bandwidth or cell is repeated or the number of repetitions, number of transmission objects, multiple access method. There is a corresponding relationship between the second information and the transmission method;
[0281] Use different transmission methods at different frequency domain positions; for example, SSBs of multiple transmission methods are transmitted at different frequency domain positions (such as on different sync.raster or sync raster + offset positions) respectively;
[0282] Use different transmission methods at different time domain positions; for example, SSBs of multiple transmission methods are sent at different time domain positions respectively
[0283] Determine the transmission method as transmission in a specified mode; for example, SSBs of multiple transmission methods are transmitted in a certain pattern;
[0284] Determine the transmission method as transmission at a specific position or time; for example, SSBs of multiple transmission methods are transmitted at a specific position or time.
[0285] After the network - side device enters the RRC connected state, for subsequent transmission objects, when the network - side device transmits, it 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 the SSB in 5G (which can also be called any module including at least one of synchronization signals, broadcast signals, physical broadcast channel (PBCH), and downlink broadcast channels for other system messages) as an example, the terminal uses the default transmission mode to receive the SSB, and the SSB carries the transmission - mode indication information for subsequent transmission objects. Among them, the indication information can be several bits explicitly carried in the MIB, or indicated by a specific value (such as a specific value indicated by the sub - carrier offset parameter of the SSB and the reference grid or reference point), etc. After receiving the SSB, the terminal can obtain the transmission - mode indication information for subsequent transmission objects (such as SIB1), and then the terminal can use the transmission mode determined in the transmission - mode indication information to transmit subsequent transmission objects. Among them, the transmission - mode indication information in the SSB can 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 one or more subsequent downlink transmission objects, or the transmission modes of one or more subsequent uplink transmission objects. Optionally, if the transmission - mode indication information in the SSB only indicates the transmission mode of the next transmission object (such as SIB1), then the transmission mode of the transmission object after SIB1 can be indicated in SIB1.
[0286] Optionally, in some embodiments, when the network - side device determines the transmission modes of at least two transmission objects, it may further include:
[0287] The network - side device determines the transmission mode according to the transmission capabilities supported by the network - side device or the related capabilities of the transmission capabilities, and there is a corresponding relationship between the transmission capabilities or the related capabilities of the transmission capabilities and the transmission mode.
[0288] 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; at least one of waveform, initialization parameter, scrambling method, sequence, phase, or rotation phase used when supporting or using different methods to transmit at least two transmission objects. When determining the transmission objects according to the transmission capability, for example, if the network-side device has the ability to receive transmission objects (such as SSB) with phase rotation, then when the network-side device sends multiple transmission objects, it can send transmission objects with phase rotation, or the terminal can detect transmission objects with phase rotation. Another example is that if the network-side device has the ability to simultaneously search for or detect transmission objects (such as SSB) generated using different initialization parameters, then when the network-side device receives multiple transmission objects, it can receive transmission objects generated using different initialization parameters, or the terminal can send transmission objects generated using different initialization parameters.
[0289] The related capabilities of the transmission capability may be, for example, the scenarios supported by the network-side device (such as TN or NTN). There is a corresponding relationship between the related capabilities of the transmission capability and the transmission method. For example, the network-side device can support working in both TN and NTN scenarios at the same time. In this case, the transmission objects in 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.
[0290] Optionally, in some embodiments, when the network-side device transmits at least one transmission object, it may further include:
[0291] 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.
[0292] The at least one transmission object here may be one or more of the at least two transmission objects in S302. At this time, the at least one transmission object is transmitted in the form of FDM or discrete frequency domain. Or, the at least one transmission object may also be other transmission objects other than the at least two transmission objects in S302. At this time, it is not required that the at least one transmission object be transmitted in the form of FDM or discrete frequency domain.
[0293] For example, for an SSB, when the network - side device transmits the SSB, a part of the SSB (such as PBCH or PBCH DMRS) can be transmitted using DFT - s - OFDM, and another part (such as PSS or SSS) can be transmitted using CP - OFDM. Among them, the SSB can be transmitted in the form of FDM or discrete frequency domain, or can be transmitted without the form of FDM or discrete frequency domain.
[0294] Optionally, as an embodiment, when the network - side device transmits at least two transmission objects, it can use DFT - s - OFDM to transmit at least two transmission objects, or, when the at least two transmission objects are frequency - domain continuous or the frequency - domain interval is less than a preset value, use DFT - s - OFDM to transmit at least two transmission objects.
[0295] In the embodiments of the present application, when the network - side device sends or receives (the 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, for one or at least two of the transmission objects, the same or different transmission methods can be used, and when transmitting in the same or different ways, at least one of the same or different waveforms, initialization parameters, scrambling methods, sequences, phases, or rotation phases can be used for transmission. Thus, in the scenario of transmitting multiple transmission objects in the form of FDM or discrete frequency domain, the terminal and the network - side device can select appropriate transmission methods for transmission, thereby reducing PAPR and ensuring coverage.
[0296] For the transmission method provided by the embodiments of the present application, the execution subject can be a transmission device.
