[0171] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0172] Step S2101: The terminal sends a first signaling.

[0173] In some embodiments, the network device receives the first signaling. Alternatively, it can be understood that the network device receives the first signaling sent by the terminal.

[0174] In some embodiments, the terminal sends a first signaling to the network device.

[0175] In some embodiments, the first signaling is used to indicate whether to configure PTRS in the uplink signal. Optionally, the first signaling is used to indicate whether to configure PTRS in the uplink signal. Optionally, the first signaling is used to indicate not to configure PTRS in the uplink signal.

[0176] In some embodiments, the first signaling is used to indicate whether to configure PTRS in uplink signals of a frequency band supported by the terminal. In some embodiments, the first signaling is used to indicate whether to configure PTRS in all uplink signals of the terminal.

[0177] In some embodiments, the first signaling is used to indicate whether the uplink signal includes PTRS. Optionally, the first signaling is used to indicate whether the uplink signal includes PTRS. Optionally, the first signaling is used to indicate whether the uplink signal includes PTRS.

[0178] In some embodiments, the uplink signal refers to a signal sent by the terminal. In some embodiments, the name of the uplink signal is not limited. The uplink signal can also be called uplink information, a first signal, etc.

[0179] In some embodiments, the PTRS is used by network devices to determine a phase difference. In some embodiments, the PTRS is used by network devices to determine a common phase difference.

[0180] In some embodiments, the name of the first signaling is not limited, and can be, for example, capability signaling, indication signaling, capability identifier, indication identifier, etc.

[0181] It should be noted that the embodiment of the present disclosure is only described by taking the example of the terminal sending a first signaling to indicate whether to configure PTRS in the uplink signal. In another embodiment, the first signaling is used to indicate whether to configure PTRS in the uplink signal for each band supported by the terminal.

[0182] In some embodiments, the above step S2101 is replaced by: for each band supported by the terminal, the terminal sends a first signaling corresponding to the band. Optionally, the first signaling is used to indicate whether PTRS is configured in the uplink signal for each band.

[0183] In some embodiments, for each band supported by the terminal, the terminal sends a first signaling, where the first signaling is used to indicate whether PTRS is configured in the uplink signal of the band.

[0184] In some embodiments, the band refers to an operating band supported by the terminal. Optionally, the terminal supports multiple bands, and for each band, the first signaling is required to indicate whether the uplink signal of the band is configured with PTRS.

[0185] For example, if the terminal supports four bands, namely band 1, band 2, band 3, and band 4, the terminal sends four first signalings, where the first signaling A corresponds to band 1, the first signaling B corresponds to band 2, the first signaling C corresponds to band 3, and the first signaling D corresponds to band 4. The first signaling A is used to indicate whether PTRS is configured in the uplink signal in band 1. The first signaling B is used to indicate whether PTRS is configured in the uplink signal in band 2. The first signaling C is used to indicate whether PTRS is configured in the uplink signal in band 3. The first signaling D is used to indicate whether a reference signal is configured in the uplink signal in band 4.

[0186] In some embodiments, the terminal sends a first signaling message indicating whether PTRS is configured in the uplink signal for each band supported by the terminal. In some embodiments, if the terminal supports four bands, the first signaling message is divided into four parts: the first part indicates whether PTRS is configured in the uplink signal for Band 1. The second part indicates whether PTRS is configured in the uplink signal for Band 2. The third part indicates whether PTRS is configured in the uplink signal for Band 3. The fourth part indicates whether PTRS is configured in the uplink signal for Band 4.

[0187] Next, how the first signaling indicates to configure PTRS in the uplink signal is described.

[0188] In some embodiments, the first signaling includes at least one indication field, and each indication field is used to indicate whether PTRS is configured in an uplink signal of a type corresponding to the indication field.

[0189] In some embodiments, the uplink signal has multiple types, and the first signaling indicates whether PTRS is configured in each type of uplink signal.

[0190] In some embodiments, the number of indication fields included in the first signaling is the same as the number of uplink signal types. For example, if the uplink signal types include two, the number of indication fields included in the first signaling is two. For example, the first indication field indicates whether the uplink signal of the first type is configured with PTRS, and the second indication field indicates whether the uplink signal of the second type is configured with PTRS.

[0191] In some embodiments, the indication field is a first value, and the first value indicates that PTRS is configured in an uplink signal of a type corresponding to the indication field.

[0192] In some embodiments, the indication field is a second value, and the second value indicates that PTRS is not configured in the uplink signal of the type corresponding to the indication field.

[0193] For example, the indicator field includes 1 bit. If the bit is 1, the first parameter is 1, indicating that PTRS is configured in the uplink signal of the type corresponding to the indicator field. If the bit is 0, the second parameter is 0, indicating that PTRS is not configured in the uplink signal of the type corresponding to the indicator field.

[0194] For another example, the indicator field includes 1 bit. If the bit is 0, the first parameter is 0, indicating that PTRS is configured in the uplink signal of the type corresponding to the indicator field. If the bit is 1, the second parameter is 1, indicating that PTRS is not configured in the uplink signal of the type corresponding to the indicator field.

[0195] It should be noted that the embodiment of the present disclosure is described by taking the indication field including 1 bit as an example. In another embodiment, the indication field may also include multiple bits, where the multiple bits indicate different parameters to indicate whether PTRS is configured in the corresponding type of uplink signal.

[0196] In some embodiments, the indication field includes a first parameter, and the first parameter indicates that PTRS is configured in an uplink signal of a type corresponding to the indication field.

[0197] In some embodiments, the indication field includes a second parameter, and the second parameter indicates that PTRS is not configured in the uplink signal of the type corresponding to the indication field.

[0198] Optionally, the solution in which the indication field includes the first parameter or the second parameter is similar to the solution in which the indication field is the first value or the second value in the above embodiment, and is not described again here.

[0199] In some embodiments, each of the at least one indication field included in the first signaling corresponds to a signal identifier, where the signal identifier is used to indicate the type of the uplink signal. For example, if indication field 1 corresponds to signal identifier 1, where signal identifier 1 indicates uplink signal type 1, then indication field 1 corresponds to uplink signal type 1. This can also be understood as indication field 1 in the first signaling being used to indicate whether the uplink signal of type 1 is configured with PTRS.

[0200] In some embodiments, the name of the signal identifier is not limited. For example, it can be a signal indication, a signal tag, a type identifier, etc. For example, the signal identifier is represented by a signal ID.

[0201] In some embodiments, the type of the uplink signal includes at least one of CP-OFDM or DFT-s-OFDM. That is, the type of the uplink signal includes CP-OFDM. Alternatively, the type of the uplink signal includes DFT-s-OFDM. Alternatively, the type of the uplink signal includes CP-OFDM or DFT-s-OFDM.

[0202] For example, the type of the uplink signal includes CP-OFDM or DFT-s-OFDM, and the first signaling includes two indication fields, the first indication field indicates whether CP-OFDM is configured with PTRS, and the second indication field indicates whether DFT-s-OFDM is configured with PTRS.

[0203] For another example, the terminal supports four frequency bands, namely band 1, band 2, band 3 and band 4, and each frequency band includes two types of uplink signals, then the terminal needs to send four first signalings, each first signaling includes two indication fields. The first indication field in the first signaling 1 indicates whether the CP-OFDM of band 1 is configured with PTRS, and the second indication field in the first signaling 1 indicates whether the DFT-s-OFDM of band 1 is configured with PTRS. The first indication field in the first signaling 2 indicates whether the CP-OFDM of band 2 is configured with PTRS, and the second indication field in the first signaling 2 indicates whether the DFT-s-OFDM of band 2 is configured with PTRS. The first indication field in the first signaling 3 indicates whether the CP-OFDM of band 3 is configured with PTRS, and the second indication field in the first signaling 3 indicates whether the DFT-s-OFDM of band 3 is configured with PTRS. The first indication field in the first signaling 4 indicates whether the CP-OFDM of band 4 is configured with PTRS, and the second indication field in the first signaling 4 indicates whether the DFT-s-OFDM of band 4 is configured with PTRS.

[0204] In some embodiments, the first signaling indicates that PTRS is configured in an uplink signal of a type corresponding to at least one of the frequency density or the time domain density by including at least one of the frequency density or the time domain density;

In another possible implementation, if the first signaling includes time-domain density, the first signaling indicates that PTRS is configured in an uplink signal of a type corresponding to the time-domain density.

[0209] Optionally, the first signaling indicates that PTRS is not configured in the uplink signal of a type corresponding to at least one of the frequency density or the time domain density by not including at least one of the frequency density or the time domain density.

[0210] In one possible implementation, if the first signaling does not include frequency density, the first signaling indicates that PTRS is not configured in the uplink signal of the type corresponding to the frequency density. In another possible implementation, if the first signaling does not include time domain density, the first signaling indicates that PTRS is not configured in the uplink signal of the type corresponding to the time domain density. In another possible implementation, if the first signaling does not include frequency density and time domain density, the first signaling indicates that PTRS is not configured in the uplink signal of the type corresponding to the frequency density and time domain density.

[0290] In some embodiments, the name of the second signaling is not limited, and can be, for example, capability signaling, indication signaling, capability identifier, indication identifier, etc.

[0291] In some embodiments, the time-frequency resource includes at least one of the following:

[0292] (1) Frequency density.

[0293] In some embodiments, the frequency density is used to indicate the frequency of PTRS.

[0294] In some embodiments, the name of the frequency density is not limited, and can be, for example, frequency range, frequency domain density, frequency domain range, etc.

[0295] (2) Time domain density.

[0296] In some embodiments, the time domain density is used to indicate the time domain of the PTRS.

[0297] In some embodiments, the name of the time domain density is not limited, and can be, for example, time domain range, time density, time range, etc.

[0298] (3) Sampling density.

[0299] In some embodiments, the sampling density is used to indicate a sampling interval of the PTRS.

[0300] In some embodiments, the sampling density is not limited in name and can be, for example, a sampling interval, a sampling frequency, etc.

[0301] In some embodiments, the second signaling includes at least one of the following: frequency density, time domain density, and sampling density.

[0302] In some embodiments, the terminal sends a first signaling and a second signaling, and if the first signaling is used to indicate that PTRS is not configured in the uplink signal of the frequency band indicated by the first signaling and the type corresponding to the first signaling, the second signaling corresponding to the frequency band and the type of uplink signal is ignored by the network device. It can also be understood that the second signaling is a signaling for indicating the parameters of the PTRS. Since the terminal has indicated to the network device through the first signaling that PTRS is not required to be configured in the uplink signal of the frequency band indicated by the first signaling and the corresponding frequency band, the network device can directly ignore the second signaling corresponding to the uplink signal of the frequency band and the type.

[0303] In some embodiments, if the first signaling indicates that PTRS is not to be configured in the uplink signal, the terminal does not perform step S2102, that is, the terminal does not send the second signaling.

[0304] It should be noted that the first signaling and the second signaling in the embodiment of the present disclosure can be one signaling, that is, the terminal sends the same signaling, which is used to indicate whether PTRS is configured in the uplink signal and also to indicate the density set of PTRS.

[0305] In some embodiments, if the first signaling and the second signaling are the same signaling, and the signaling is used to indicate that PTRS is not configured in the uplink signal, the frequency domain resources of the PTRS indicated by the signaling are ignored by the network device.

[0306] It should be noted that the embodiments of the present disclosure are described using the example of whether the first signaling includes frequency density, time domain density, and sampling density to indicate whether PTRS is configured in the uplink signal. In another embodiment, the first signaling in the embodiments of the present disclosure may also be second signaling, which can also be understood as the terminal sending the second signaling, where the second signaling indicates whether PTRS is configured in the uplink signal by whether it includes frequency density, time domain density, and sampling density. Alternatively, it can be understood that the second signaling has the same function as the first signaling, and the terminal can directly send the second signaling.

[0307] In some embodiments, if the first signaling is used to indicate that PTRS is not configured in the uplink signal, the second signaling is ignored.

[0308] In some embodiments, the terminal sends the second signaling, and the network device receives the second signaling. In other embodiments, step S2102 may not be performed, and the network device may obtain the second signaling through other means.

[0309] Optionally, the network device obtains second signaling specified by the protocol.

[0310] Optionally, the network device obtains the second signaling from a higher layer.

[0311] Optionally, the network device performs processing to obtain the second signaling.

[0312] Optionally, the network device autonomously implements the function indicated by the second signaling, or the above function is default or acquiescent.

[0313] Step S2103: The network device determines whether to configure PTRS according to the first signaling instruction.

[0314] In some embodiments, configuring the PTRS on a network device refers to configuring resources of the PTRS on the network device.

[0315] In some embodiments, if the first signaling indicates that PTRS is not to be configured in the uplink signal, the network device does not configure PTRS.

[0316] In some embodiments, if the first signaling indicates that PTRS is not to be configured in the uplink signal, the network device does not configure resources for the phase reference signal.

[0317] In some embodiments, the first signaling includes at least one indication field, and each indication field is used to indicate whether PTRS is configured in an uplink signal of a type corresponding to the indication field.

[0318] In some embodiments, the first signaling indicates that PTRS is configured in an uplink signal of a type corresponding to at least one of the frequency density or the time domain density by including at least one of the frequency density or the time domain density;

[0319] and / or,

[0320] The first signaling indicates that PTRS is not configured in the uplink signal of the type corresponding to at least one of the frequency density or the time domain density by not including at least one of the frequency density or the time domain density.

[0321] In some embodiments, the first signaling indicates that the PTRS is configured in an uplink signal of a type corresponding to the sampling density by including a sampling density;

[0322] and / or,

[0323] The first signaling indicates that the PTRS is not configured in the uplink signal of the type corresponding to the sampling density by not including the sampling density.

[0324] It should be noted that in the embodiments of the present disclosure, the present disclosure uses the example of whether the first signaling includes frequency density, time domain density, and sampling density to indicate whether PTRS is configured in the uplink signal. In another embodiment, the first signaling in the embodiments of the present disclosure may also be second signaling, which can also be understood as the terminal sending the second signaling, and the second signaling indicates whether PTRS is configured in the uplink signal by whether it includes frequency density, time domain density, and sampling density. Alternatively, it can also be understood that the second signaling has the same function as the first signaling, and the terminal can directly send the second signaling.

[0325] In some embodiments, if the second signaling indicates that PTRS is not to be configured in the uplink signal, the network device does not configure PTRS.

[0326] In some embodiments, if the second signaling indicates that PTRS is not to be configured in the uplink signal, the network device does not configure resources for the phase reference signal.

[0327] In some embodiments, the second signaling includes at least one indication field, and each indication field is used to indicate whether PTRS is configured in an uplink signal of a type corresponding to the indication field.

[0328] In some embodiments, the second signaling indicates that PTRS is configured in an uplink signal of a type corresponding to at least one of the frequency density or the time domain density by including at least one of the frequency density or the time domain density;

[0329] and / or,

[0330] The second signaling indicates that PTRS is not configured in the uplink signal of the type corresponding to at least one of the frequency density or the time domain density by not including at least one of the frequency density or the time domain density.

[0331] In some embodiments, the second signaling indicates that the PTRS is configured in an uplink signal of a type corresponding to the sampling density by including a sampling density;

[0332] and / or,

[0333] The second signaling indicates that the PTRS is not configured in the uplink signal of the type corresponding to the sampling density by not including the sampling density.

[0334] It should be noted that if the first signaling indicates whether PTRS is configured in the uplink signal by means of an indication field, and the second signaling implicitly indicates whether PTRS is configured in the uplink signal, the indication of the first signaling shall prevail. Alternatively, if the first signaling indicates whether PTRS is configured in the uplink signal by means of an indication field, and the second signaling implicitly indicates whether PTRS is configured in the uplink signal, the indication of the second signaling shall prevail. This is not limited in the present embodiment.

[0453] FIG6 is a flow chart of a communication method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a communication method, and the method includes:

[0454] In step S6101, the terminal reports whether PTRS needs to be configured in the uplink transmission signal for each band.

[0455] In some embodiments, different capabilities may be signaled for different signal waveforms (CP-OFDM and DFT-s-OFDM). The capability signaling may be in the form of a bitmap, such as PTRS-UL INTEGER (1…2). Bit 1 may be used to indicate whether a terminal requires PTRS configuration when supporting the CP-OFDM waveform. Setting this bit to 1 indicates that the terminal requires PTRS configuration, while setting this bit to 0 indicates that the terminal does not require PTRS configuration. Bit 2 indicates whether a terminal requires PTRS configuration when supporting the DFT-s-OFDM waveform. Setting this bit to 1 indicates that the terminal requires PTRS configuration, while setting this bit to 0 indicates that the terminal does not require PTRS configuration.

[0456] In some embodiments, when the terminal indicates through this capability that PTRS configuration is required for the CP-OFDM waveform, the terminal needs to simultaneously report the preferred threshold set of uplink PTRS density through the signaling ptrs-DensityRecommendationSetUL.

[0457] In some embodiments, when the terminal indicates through this capability that PTRS configuration is required for the DFT-s-OFDM waveform, the terminal needs to simultaneously report the preferred threshold set of uplink PTRS density through signaling ptrs-DensityRecommendationSetUL.

[0458] Optionally, the network device configures a corresponding UL PTRS for the terminal according to the capability indication of the terminal and the corresponding configuration waveform.

[0459] In some embodiments, when a terminal indicates through this capability that it does not require PTRS configuration for a CP-OFDM waveform, or when a terminal indicates through this capability that it does not require PTRS configuration for a DFT-s-OFDM waveform, the network device ignores the signaling ptrs-DensityRecommendationSetUL message and does not configure any PTRS for the terminal on the corresponding configured waveform.

[0460] In some embodiments, the terminal extends the signaling ptrs-DensityRecommendationSetUL. Currently, this signaling includes three parameters: frequency density (frequencyDensity) and time density (timeDensity), which are used to report the preferred threshold set for uplink PTRS density in the CP-OFDM waveform. Sample density (sample density) is used to report the preferred threshold set for uplink PTRS density in the DFT-s-OFDM waveform.

[0461] Optionally, when the terminal defaults to frequency density and / or time density, it indicates that the terminal does not require PTRS configuration for the CP-OFDM waveform. When the terminal defaults to sample density, it indicates that the terminal does not require PTRS configuration for the DFT-s-OFDM waveform. Correspondingly, the network device does not configure any PTRS for the terminal on the corresponding configured waveform.

[0462] Optionally, if the terminal reports frequency density (frequencyDensity) and corresponding time density (timeDensity) and / or sampling density (Sample density), the network device configures PTRS for the terminal on the corresponding configuration waveform.

[0463] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0464] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions. The processor calls the instructions stored in the memory to implement any of the above methods or implement the functions of the various units or modules of the above device, wherein the processor is, for example, a general-purpose processor, such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device.
