After the network side device indicates multiple PUSCH power control parameter identification sets to the terminal device through DCI, the terminal device can calculate multiple PUSCH transmit powers.

The terminal equipment calculates multiple PUSCH transmission powers in at least two ways as follows.

The first:

In the embodiment of the present invention, the PUSCH power control parameters corresponding to each PUSCH power control parameter identification set include: target received power, path loss compensation factor, path loss calculation reference reference signal, and closed-loop process.

In an embodiment, when the network side device configures the terminal device to send multiple PUSCHs at the same time, the network side device can indicate multiple PUSCH power control parameter identification sets to the terminal device through DCI. The terminal equipment can determine the target received power, path loss compensation factor, path loss calculation reference signal and closed-loop process corresponding to each PUSCH power control parameter identification set based on multiple PUSCH power control parameter identification sets, and then determine the target received power, path loss compensation factor, path loss calculation reference signal and closed-loop process according to each PUSCH power control parameter identification set. The target received power, path loss compensation factor, path loss calculation reference signal and closed-loop process corresponding to the parameter identification set are used to calculate multiple PUSCH transmit powers, so that when the terminal equipment transmits multiple PUSCHs at the same time, different PUSCHs use different transmit powers. This effectively improves the transmission rate of sending multiple PUSCHs at the same time.

For example, the network side configures a PUSCH power control parameter identifier set for the terminal device through RRC signaling: SRS resource indication field value 0, SRS resource indication field value 1, and SRS resource indication field value 0: PUSCH power control parameter identifier set 0 , a PUSCH power control parameter identification set corresponding to the SRS resource indication field value 1: PUSCH power control parameter identification set 1.

The path loss compensation factor 1 corresponding to the factor identifier 1, the path loss calculation reference signal 1 corresponding to the path loss calculation reference signal 1, and the closed-loop process 1 corresponding to the closed-loop process identifier 1, and then the terminal equipment is based on the target received power 1, path Loss compensation factor 1, path loss calculation reference signal 1 and closed-loop process 1 are used to calculate the second PUSCH transmit power corresponding to the second PUSCH using a preset algorithm.

Furthermore, the terminal equipment uses the first PUSCH transmission power to transmit the first PUSCH according to the PUSCH space related information indicated by the SRS resource indication field value 0; at the same time, according to the PUSCH space related information indicated by the SRS resource indication field value 1, the terminal equipment uses the second PUSCH to transmit power to transmit the second PUSCH.

It should be noted that when the network side device configures the terminal device to transmit multiple PUSCHs at the same time, different PUSCHs can use different transmission powers; or, some PUSCHs among multiple PUSCHs can use the same transmission power, and some PUSCHs can use different transmission powers. Transmitting power is not specifically limited here.

When the network side device configures at least one PUSCH power control parameter identification set corresponding to each SRS resource indication domain value through RRC signaling, it can also configure the antenna port set corresponding to each PUSCH power control parameter identification set, so that at the terminal When the device transmits different antenna port sets of the same PUSCH at the same time, the PUSCH transmit power corresponding to the antenna port set can be calculated based on the PUSCH power control parameter identification set corresponding to the antenna port set.

The terminal equipment determines the PUSCH power control parameters corresponding to the PUSCH power control parameter identifier set 1 according to the PUSCH power control parameter identifier set 1 corresponding to the SRS resource indication field value 0: the target received power 1 corresponding to the target received power identifier 1, and path loss compensation. The path loss compensation factor 1 corresponding to the factor identifier 1, the path loss calculation reference signal 1 corresponding to the path loss calculation reference signal 1, and the closed-loop process 1 corresponding to the closed-loop process identifier 1, and then the terminal equipment is based on the target received power 1, path Loss compensation factor 1, path loss calculation reference signal 1 and closed-loop process 1 are used to calculate the second PUSCH transmit power corresponding to antenna port set 2 using a preset algorithm.

Furthermore, the terminal equipment uses the first PUSCH transmission power to transmit PUSCH on antenna port set 0 according to the PUSCH space related information indicated by the SRS resource indication field value 0; at the same time, according to the PUSCH space related information indicated by the SRS resource indication field value 0, on The second PUSCH transmission power is used to transmit PUSCH on antenna port set 2.

It should be noted that when the network side device configures the terminal device to transmit multiple antenna port sets of a PUSCH at the same time, different antenna port sets can use completely different transmission powers; or, some antenna port sets in the multiple antenna port sets The same transmit power can be used, and some antenna port sets can use different transmit powers, which are not specifically limited here.
