Referring to fig. 2, fig. 2 is a flowchart of an information receiving method according to an embodiment of the present application, and as shown in fig. 2, the information receiving method includes the following steps:

step 101, a terminal receives downlink control information (Downlink Control Information, DCI) sent by network side equipment and/or target configuration information;

wherein the DCI is used to determine whether to switch an uplink transmission waveform or determine an uplink transmission waveform under multiple transmission and reception points (Transmission Reception Point, TRP) transmission;

the target configuration information is used for configuring an uplink transmission waveform, and is the configuration information of a reference signal or the configuration information corresponding to a physical cell identifier (Physical Cell Identifier, PCI) under multi-TRP transmission.

In one embodiment, the network side device may explicitly or implicitly indicate an uplink transmission waveform under a multi-TRP (mTRP) transmission through DCI.

In one embodiment, the network side device may explicitly or implicitly indicate whether to switch the uplink transmission waveform under the multi-TRP transmission through DCI.

In one embodiment, the network side device may explicitly indicate the uplink transmission waveform through one or more information fields in the DCI, or whether to switch the uplink transmission waveform.

It should be understood that, DCI is dynamic control signaling, and by determining whether to switch an uplink transmission waveform or determine an uplink transmission waveform under multi-TRP transmission, dynamic switching of an uplink transmission waveform of uplink transmission by a terminal can be implemented, and flexibility is high, compared with static or semi-static configuration of an uplink transmission waveform.

It should be understood that the target configuration information may be configuration information of a reference signal, and different reference signals may be indicated by switching of different TRPs, so that dynamic switching of uplink transmission waveforms for uplink transmission by the terminal is implemented through configuration information of different reference signals, and flexibility is high.

It should be understood that the target configuration information may be configuration information corresponding to the PCI in the multi-TRP transmission, and the dynamic switching of the uplink transmission waveform of the uplink transmission can be implemented by the terminal through different PCIs, which has higher flexibility.

As an example, the target configuration information may be used to configure whether an uplink transmission waveform or an uplink transmission waveform applied to an uplink channel associated with the RS is switched or whether an uplink transmission waveform or an uplink transmission waveform applied to an uplink channel associated with the sounding Reference Signal (Sounding Reference Signal, SRS) is switched in a Reference Signal (RS) resource (resource) or resource set (resource set) configuration corresponding to the TRP.

It should be appreciated that in embodiments of the present application, the RS may characterize the RS signal itself, and/or may characterize the RS resources; the SRS may characterize the SRS signal itself, and/or may characterize SRS resources.

The NR system supports downlink multi-TRP transmission, and includes a transmission method based on single DCI (S-DCI) and a transmission method based on multi-DCI (M-DCI), where the transmission method includes methods such as space division multiplexing (Space Division Multiplexing, SDM), frequency division multiplexing (Frequency division multiplex, FDM), time division multiplexing (Time division multiplexing, TDM), and single frequency repeated transmission (SFN). The transmission based on multiple DCIs is based on the assumption that link delays among multiple TRPs are large and cannot be interacted in real time. The NR system supports uplink multi-TRP transmission and also supports transmission methods based on single DCI and multiple DCIs. The NR system also instructs the uplink beam switch transmission and the uplink beam switch mode to be configured by radio resource control (Radio Resource Control, RRC) signaling. There are three ways of uplink beam switching: the two beams are alternately switched (namely, the first beam and the second beam are alternately switched), the two beams are alternately switched (namely, the first beam is sent 2 times and the second beam is sent 2 times), and half of the beams are switched (namely, the first half of the first beam and the second half of the second beam are used). In a single DCI (S-DCI) transmission method, the DCI may include 2 transmission precoding matrix indicator (Transmitted precoding matrix indicator, TPMI) fields and 2 SRS resource indicator (SRS resource indicator, SRI) fields, where the directions of uplink physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission are indicated by the 2 SRIs, that is, one SRI field corresponds to a first TRP transmission and the other SRI field corresponds to a second TRP transmission.

In the related art, two waveforms are supported by the NR system uplink, and are respectively: DFT-s-OFDM waveform and CP-OFDM waveform, DFT-s-OFDM waveform is single carrier wave waveform, CP-OFDM waveform is multi-carrier wave waveform, up-line transmission waveform can be configured by RRC signaling, configured up-line transmission waveform can not be changed dynamically, flexibility is poor.

Optionally, the DCI is used to indicate at least one of:

uplink transmission waveforms;

whether to switch the uplink transmission waveform;

the switching mode of the uplink transmission waveform.

In one embodiment, the DCI may be used to indicate an uplink transmission waveform as a first waveform or a second waveform.

The first waveform may be a discrete fourier transform spread orthogonal frequency division multiplexing DFT-s-OFDM waveform and the second waveform may be an orthogonal frequency division multiplexing CP-OFDM waveform with a cyclic prefix.

In one embodiment, the DCI may be used to indicate switching of an uplink transmission waveform or not switching of an uplink transmission waveform.

In one embodiment, the DCI may be used to instruct switching of an uplink transmission waveform using a first waveform switching mode or not switching of an uplink transmission waveform.

The first waveform switching mode may be alternate beam switching, or alternate beam switching of two beams, or half-half beam switching.

In one embodiment, the DCI may be used to instruct switching of the uplink transmission waveform in the second waveform switching manner or not switching of the uplink transmission waveform.

In one embodiment, the DCI may be used to instruct switching of an uplink transmission waveform using a first waveform switching mode or a second waveform switching mode, or not switching of an uplink transmission waveform.

The first waveform switching manner may be: the first transmission uses a first waveform, the second transmission uses a second waveform, the third transmission uses a first waveform, the fourth transmission uses a second waveform, and so on.

The second waveform switching method may be: in N uplink transmissions corresponding to the multi-TRP transmission, the first N/2 times adopts a first waveform, and the second N/2 times adopts a second waveform.

Optionally, the DCI is used to determine whether to switch an uplink transmission waveform or determine an uplink transmission waveform under multi-TRP transmission in a time division multiplexing TDM manner.

In this embodiment, the DCI is used to determine whether to switch an uplink transmission waveform or determine an uplink transmission waveform under the multi-TRP transmission in the TDM manner, so that, under the multi-TRP transmission in the TDM manner, the terminal can determine whether to switch the uplink transmission waveform or determine the uplink transmission waveform through the DCI, and can realize dynamic switching of the uplink transmission waveform of uplink transmission by the terminal, which has high flexibility.

Optionally, the DCI includes at least one of:

first indication information, wherein the first indication information is used for indicating uplink transmission waveforms of a plurality of uplink transmissions corresponding to the multi-TRP transmission;

second indication information, where the second indication information is used to indicate whether the uplink transmission waveforms are switched by the uplink transmissions corresponding to the multi-TRP transmission;

A third indication information, where the third indication information is used to indicate a switching manner of uplink transmission waveforms of multiple uplink transmissions corresponding to the multi-TRP transmission;

fourth indication information, the fourth indication information is used for indicating uplink transmission waveforms corresponding to each TRP transmission in the multi-TRP transmission.

The multiple uplink transmissions corresponding to the multi-TRP transmission may be N uplink transmissions corresponding to the multi-TRP transmission, where N is a positive integer greater than 1.

In addition, the first indication information may be 1bit (bit) or more than one bit of indication information. When determining an uplink transmission waveform from only two waveforms, 1bit of first indication information may be employed; when determining an uplink transmission waveform from among three or more waveforms, the first indication information of more than 1bit may be employed. Taking 1bit first indication information as an example, the 1bit first indication information may be used to characterize two states. For example, one state of the first indication information is used to indicate a first waveform, and the other state of the first indication information is used to indicate a second waveform, and the terminal uses the waveform indicated by the first indication information as an uplink transmission waveform in the plurality of uplink transmissions corresponding to the multi-TRP transmission. For example, the terminal adopts the waveform indicated by the first indication information in N uplink transmissions.

In addition, the second indication information may be 1bit (bit) or more than one bit of indication information. When the uplink transmission waveform is determined from only two waveforms, 1-bit second indication information may be employed; when determining the uplink transmission waveform from among three or more waveforms, the second indication information of more than 1bit may be employed. Taking the 1bit second indication information as an example, the 1bit second indication information may be used to characterize two states. For example, one state of the second indication information is used to indicate switching of an uplink transmission waveform, and the other state of the second indication information is used to indicate non-switching of an uplink transmission waveform, and the terminal switches or does not switch the uplink transmission waveform based on the indication of the second indication information in the plurality of uplink transmissions corresponding to the multi-TRP transmission. For example, the terminal switches or does not switch the uplink transmission waveform based on the indication of the second indication information in N uplink transmissions.

In addition, the third indication information may be 1bit (bit) or more than one bit of indication information. When there are only two switching modes of the uplink transmission waveform, the third indication information of 1bit can be adopted; when there are three or more switching modes of the uplink transmission waveform, the third indication information greater than 1bit may be used. Taking the third indication information of 1bit as an example, the third indication information of 1bit can be used to characterize two states. For example, a state of the third indication information is used to indicate a rotation waveform switching manner of the uplink transmissions corresponding to the multi-TRP transmission; another state of the third indication information is used to indicate that the uplink transmission waveform is not switched when the multiple TRP transmission corresponds to the multiple uplink transmission, that is, the same waveform is adopted when the multiple TRP transmission corresponds to the multiple uplink transmission, and the adopted same waveform may be pre-agreed, or determined according to other information, for example: the transmission modulation and coding scheme (Modulation and coding scheme, MCS) or rank (rank), or by RRC configuration. The alternate waveform switching manner indicated by the third indication information may be: the first transmission adopts a first waveform, the second transmission adopts a second waveform, the third transmission adopts a first waveform, the fourth transmission adopts a second waveform, and the like; alternatively, the alternate waveform switching manner indicated by the third indication information may be: in N uplink transmissions corresponding to the multi-TRP transmission, the first waveform is adopted for the first N/2 times, the second waveform is adopted for the last N/2 times, if N is not even, the first N/2 is rounded up and the last N/2 is rounded down, or the first N/2 is rounded down and the last N/2 is rounded up.

In addition, the number of bits of the fourth indication information may be equal to the number of TRPs, and an uplink transmission waveform of each bit in the fourth indication information for indicating one TRP transmission is the first waveform or the second waveform.

In addition, in this embodiment, the number of DCIs may be one, and uplink transmission waveforms for multiple TRP uplink transmissions are determined by a single DCI.

It should be noted that, if the uplink beam switching is configured, the uplink transmission waveform switching and the uplink beam switching may be used in combination, for example, when the DCI indicates the uplink beam switching and is configured in a certain beam switching manner, the first waveform may be corresponding to the first beam, the second waveform may be corresponding to the second beam, and the uplink transmission waveform is switched by switching the beams.

Considering that different TRPs or different beams (beams) may correspond to different Power Amplifier (PA) requirements under different network application scenarios. The embodiment of the application provides a waveform switching method for corresponding transmission of different TRPs or beams, so that the corresponding transmission of the different TRPs or beams can use different waveforms, or the corresponding transmission of the different types of TRPs or beams can use different waveforms.

In this embodiment, the first indication information terminal can determine uplink transmission waveforms of the plurality of uplink transmissions corresponding to the multi-TRP transmission, the second indication information terminal can determine whether or not the plurality of uplink transmissions corresponding to the multi-TRP transmission are to be switched, the third indication information terminal can determine a switching manner of the plurality of uplink transmission waveforms of the plurality of uplink transmissions corresponding to the multi-TRP transmission, and the fourth indication information terminal can determine uplink transmission waveforms corresponding to each of the multi-TRP transmission.

Optionally, in the multi-TRP transmission of the frequency division multiplexing FDM mode or the space division multiplexing SDM mode, uplink transmission waveforms of the plurality of uplink transmissions corresponding to the multi-TRP transmission are the same.

Optionally, the number of DCIs is plural, and each DCI in the plurality of DCIs is used to schedule one uplink transmission.

In this embodiment, the terminal can determine whether to switch the uplink transmission waveform or determine the uplink transmission waveform by using the plurality of DCIs under the multi-TRP transmission, so that the terminal can dynamically switch the uplink transmission waveform of the uplink transmission, and the flexibility is high.

Optionally, when the uplink transmissions scheduled by the plurality of DCIs are sent at different times, a first DCI is used to determine an uplink transmission waveform of the uplink transmission corresponding to the first DCI, where the first DCI is any one of the plurality of DCIs.

The uplink transmission scheduled by the DCI may be a PUSCH scheduled by the DCI. The uplink transmission waveform of the uplink transmission corresponding to the DCI may be an uplink transmission waveform corresponding to the PUSCH scheduled by the DCI.

For example, taking 2 DCIs as an example, 2 DCIs are used as the plurality of DCIs, 2 independent PUSCHs are scheduled by the 2 DCIs, and when the scheduled 2 PUSCHs are transmitted at different times, the uplink transmission waveform corresponding to each PUSCH is determined according to the manner indicated in the respective DCIs.

In this embodiment, when the plurality of DCI scheduled uplink transmissions are transmitted at different times, the first DCI is used to determine an uplink transmission waveform of the uplink transmission corresponding to the first DCI, so that the uplink transmission waveform of the DCI scheduled uplink transmission can be determined by each of the plurality of DCIs.

Optionally, in a case where the plurality of DCI scheduled uplink transmissions are transmitted at the same time, the method further includes at least one of:

the terminal determines an uplink transmission waveform of uplink transmission corresponding to second DCI according to the second DCI, wherein the second DCI is any one of the plurality of DCIs;

the terminal only transmits uplink transmission corresponding to a first uplink transmission waveform, wherein the first uplink transmission waveform is one of the uplink transmission waveforms indicated by the DCI;

And the terminal adopts a second uplink transmission waveform to transmit the uplink transmissions scheduled by the DCIs, wherein the second uplink transmission waveform is one of the uplink transmission waveforms indicated by the DCIs.

The first uplink transmission waveform may be specified by a protocol, or configured by a network side device. The second uplink transmission waveform may be specified by a protocol or configured by a network side device.

In addition, the terminal may also instruct the network side device about an uplink transmission waveform used for uplink transmission. Under the condition that the terminal only sends uplink transmission corresponding to a first uplink transmission waveform, the terminal indicates the first uplink transmission waveform to network side equipment; and under the condition that the terminal adopts a second uplink transmission waveform to send a plurality of uplink transmissions scheduled by the DCI, the terminal indicates the second uplink transmission waveform to network side equipment.

For example, taking 2 DCIs as an example of the plurality of DCIs, 2 DCIs schedule 2 independent PUSCHs, and when the scheduled 2 PUSCHs are transmitted at the same time, the terminal performs any one of the following:

the terminal determines an uplink transmission waveform corresponding to each PUSCH according to the DCI corresponding to the PUSCH;

The terminal only transmits uplink transmission corresponding to one of the waveforms, for example, the terminal only transmits PUSCH corresponding to DFT-s-OFDM waveform, and does not transmit PUSCH corresponding to CP-OFDM waveform;

the terminal transmits 2 PUSCHs using one waveform, for example, the terminal transmits 2 PUSCHs using a DFT-s-OFDM waveform.

In this embodiment, when the uplink transmissions scheduled by the plurality of DCIs are transmitted at the same time, the terminal determines, according to the second DCI, an uplink transmission waveform of the uplink transmission corresponding to the second DCI; and/or, the terminal only sends the uplink transmission corresponding to the first uplink transmission waveform; and/or, the terminal adopts a second uplink transmission waveform to transmit the plurality of uplink transmissions scheduled by the plurality of DCIs. In this way, the terminal can determine uplink transmission waveforms through a plurality of DCIs under multi-TRP transmission, and can realize dynamic switching of uplink transmission waveforms of uplink transmission by the terminal, so that the flexibility is high.

Optionally, the determining manner of the first uplink transmission waveform and/or the second uplink transmission waveform is any one of the following:

specified by a protocol;

configured by the network side equipment.

Optionally, the target configuration information is configuration information of a reference signal corresponding to the TRP.

The target configuration information may be configuration information of a reference signal corresponding to a single (TRP) TRP; alternatively, the configuration information may be configuration information of a reference signal corresponding to a TRP under a multi TRP (mTRP).

In this embodiment, the target configuration information is the configuration information of the reference signal corresponding to the TRP, so that different reference signals can be indicated by switching of different TRPs, and thus, dynamic switching of uplink transmission waveforms of uplink transmission by the terminal is realized by the configuration information of different reference signals, and flexibility is high.

Optionally, the target configuration information is used to indicate any one of the following:

an uplink transmission waveform of an uplink channel associated with the at least one reference signal RS;

whether an uplink transmission waveform of an uplink channel associated with at least one RS is switched;

an uplink transmission waveform of an uplink channel associated with at least one sounding reference signal, SRS;

whether the uplink transmission waveform of the uplink channel associated with the at least one sounding reference signal SRS is switched.

The RS may be at least one of SRS, channel state information Reference Signal (CSI-RS), and synchronization Signal block (Synchronization Signal Block, SSB). The uplink channel may be PUSCH.

In one embodiment, the target configuration information may be used to indicate any of the following:

whether or not the uplink transmission waveform of the uplink channel associated with the SRS corresponding to the TRP is switched.

It should be noted that different RSs may be associated with different TRPs, so that different associated RSs are indicated by the transformation of different TRPs, so as to implement switching of uplink transmission waveforms.

In this embodiment, the target configuration information is used to indicate whether the uplink transmission waveform or the uplink transmission waveform of the uplink channel associated with the at least one reference signal RS is switched, and/or whether the uplink transmission waveform or the uplink transmission waveform of the uplink channel associated with the at least one sounding reference signal SRS is switched, so that whether the uplink transmission waveform or the uplink transmission waveform of the uplink channel associated with the RS is switched can be determined through the target configuration information, and/or whether the uplink transmission waveform or the uplink transmission waveform of the uplink channel associated with the SRS is switched can be determined through the target configuration information, so that dynamic switching of the uplink transmission waveform of uplink transmission by the terminal can be achieved, and flexibility is high.

Optionally, the at least one RS corresponds to a first TRP, or the at least one SRS corresponds to a second TRP.

In this embodiment, the at least one RS corresponds to a first TRP, or the at least one SRS corresponds to a second TRP, so that whether an uplink transmission waveform or an uplink transmission waveform of an uplink channel associated with the RS corresponding to the first TRP is switched can be determined through the target configuration information; or, whether the uplink transmission waveform or the uplink transmission waveform of the uplink channel associated with the SRS corresponding to the second TRP is switched or not may be determined through the target configuration information. Therefore, the dynamic switching of the uplink transmission waveform of the terminal for uplink transmission can be realized, and the flexibility is high.

Optionally, the target configuration information includes at least one of:
