It should be further noted that, optionally, the multiple uplink transmissions and the target object are located in the same serving cell (serving cell), carrier (carrier) or frequency location (frequency location); or

The multiple uplink transmissions and the target object are located in different serving cells, carriers or frequency locations.

It should be noted that when the terminal performs the first transmission and the network side device instructs the terminal to perform the second transmission at the interval between multiple uplink transmissions included in the first transmission, the terminal may directly perform the first operation , or, it is also possible to first determine whether it has the first capability. In the case of having the first capability, the terminal does not need to perform the first operation, and can implement both the first transmission and the second transmission. If the terminal does not have the first capability In this case, the terminal performs the first operation.

It should be noted here that the first capability is: the capability to ensure that the preset transmission conditions are satisfied between the multiple uplink transmissions, that is, the situation in which the terminal performs downlink reception or uplink transmission in the interval of multiple uplink transmissions In this case, it can be ensured that the receiving end obtains channel estimates of other uplink transmissions in the multiple uplink transmissions based on the DMRS of one uplink transmission in the multiple uplink transmissions.

The specific implementation manner of the present application is illustrated below with an example.

For example, as shown in FIG. 3 , if there is a gap (gap) of X symbols between multiple first transmissions, and multiple uplink transmissions need to satisfy the transmission property of DMRS bundling. If the network configures PDCCH monitoring or CSI-RS reception within these X symbols, the terminal does not perform these downlink receptions.

Likewise, if the network configures the SSB or the CSI-RS to perform the first measurement within the X symbols, the terminal does not perform the first measurement.

For example, as shown in FIG. 4 , if there is an interval of X symbols between multiple first transmissions, the target object will not be sent during the duration corresponding to the interval of X symbols, including at least one of the following :

B11. The UE does not send SRS between multiple uplink transmissions;

B12. The UE does not send PRACH between multiple uplink transmissions;

B13. The UE does not send MSG3 between multiple uplink transmissions;

B14. The UE does not send the MSG-A PUSCH between multiple uplink transmissions;

B15. The UE does not send CG-PUSCH between multiple DG-PUSCHs;

B17. The UE does not send different physical channels between multiple uplink transmissions.

B18. The UE does not send PUCCHs in different formats, UCI information, or PUCCHs with different UCI information lengths between multiple PUCCH uplink transmissions.

Due to different uplink transmissions, according to the existing power control mechanism, there may be different uplink transmission powers. If the power changes during the duration of multiple uplink transmissions, the UE cannot keep the power constant and the phase continuous. Then, among the multiple uplink transmissions of the first transmission, the network cannot obtain another uplink transmission channel based on the DMRS of one of the transmissions during reception. Cancelling the transmission of other channels in the middle can ensure that the first uplink transmission can still ensure constant power or continuous phase, so that other uplink transmission channels can still be obtained based on the DMRS of one of the uplink transmissions.

Preferably, the uplink transmission of the target object can be cancelled after further meeting some of the following conditions, including at least one of the following:

C11. The modulation mode is different from the modulation modes of the multiple uplink transmissions;

a) Note: To avoid the variation of transmit power between different uplink transmissions caused by different modulation methods.

C12, the path loss (Pathloss) RS is different from the path loss (Pathloss) RS of the multiple uplink transmissions;

a) Note: Different uplink transmissions may correspond to different path loss (Pathloss) RSs, which will cause the UE to calculate different transmit powers according to the path loss (Pathloss) RSs.

C13, the codebook (codebook) is different from the codebook (codebook) of the multiple uplink transmissions;

a) Note: Different codebooks may cause the total transmit power of the UE, or the transmit power on a certain transmit antenna to vary.

C14. The TCI state (state) is different from the TCI state (state) of the multiple uplink transmissions;

a) Note: Different TCI states mean that different uplink beams may be used for transmission between different transmissions, which no longer meets the transmission characteristics of DMRS bundling.

C15. The bandwidth of the transmitted signal is different from the bandwidth of the multiple uplink transmissions;

a) The bandwidth includes at least one of the bandwidth size (RB number) and the frequency position;

b) Different transmission bandwidths may involve RF retuning, so the phase continuity cannot be guaranteed, and the transmission characteristics of DMRS bundling cannot be guaranteed.

C16, the waveform is different from the waveforms of the multiple uplink transmissions, for example:

a) The first transmission is a DFT-S-OFDM waveform, and the target object is a CP-OFDM waveform;

b) The first transmission is a CP-OFDM waveform, and the target object is a DFT-S-OFDM waveform;

For example, if two PUSCHs are PUSCHs with DFT-S-OFDM waveforms, then the gap in the middle can transmit PUSCH if the transmission power can be guaranteed to be the same (for example, beams, pathloss RS, modulation methods are the same, etc.) /PUCCH. But if the waveforms are different, the PUSCH is not sent. Among them, the waveform of PUCCH format (format) 0, format (format) 1, format (format) 3, format (format) 4 can be considered as DFT-S-OFDM waveform; PUCCH format (format) The waveform of 2 can be considered as CP - OFDM waveform.

c) Note (Note): The radio frequency indexes corresponding to different transmission waveforms, for example, MPR, etc. are different, and the same transmission power cannot be guaranteed.

C17. The transmit power of the target object is different from the power of the first uplink transmission;

a) The target object may be in the same or different serving cell (serving cell), carrier (carrier) or frequency (frequency) as the first transmission.

C18. The subcarrier spacing is different.

Or as a further requirement, other uplink transmissions in the interval of multiple uplink transmissions of the first transmission can be transmitted when at least one of the following conditions is satisfied:

C21, the modulation mode is the same as the modulation mode of the multiple uplink transmissions;

C22, the path loss (Pathloss) RS is the same as the path loss (Pathloss) RS of the multiple uplink transmissions;

C23, the codebook (codebook) is the same as the codebook (codebook) of the multiple uplink transmissions;

C24, the TCI state is the same as the TCI state of the multiple uplink transmissions;

C25. The bandwidth of the transmitted signal is the same as the bandwidth of the multiple uplink transmissions;

Specifically, the bandwidth includes at least one of a bandwidth size (number of RBs) and a frequency position.

C26, the waveform is the same as the waveforms of the multiple uplink transmissions;

C27, the transmission power of the target object and the first uplink transmission are the same;

C28, the subcarrier spacing is the same.

It should be noted that, by canceling the uplink transmission or downlink reception between multiple uplink transmission intervals of DMRS bundling, it is ensured that the terminal can ensure constant power and phase continuity, thereby ensuring that the network side can perform DMRS bundling ( bundling) channel estimation to obtain better reception performance.
