Example Embodiment
[0061] Embodiment 1.
[0062] Power adjustment δ PUCCHis: in the M downlink subframes of a carrier group in which UCI is transmitted in the PUCCH on the uplink carrier, each power adjustment amount δ indicated by the PDCCH / EPDCCH received on a designated downlink carrier in the carrier group PUCCH ; That is, when a PUCCH only feeds back the UCI of one carrier group, for a carrier group that has a corresponding relationship with the uplink carrier (that is, pre-configured or agreed, the uplink carrier is the carrier group corresponding to the carrier group and used to transmit the carrier through the PUCCH. δ received in M downlink subframes in the uplink carrier of UCI) PUCCH When summing, each downlink subframe only accumulates one δ indicated by one PDCCH / EPDCCH PUCCH , the PDCCH / EPDCCH is received on a designated downlink carrier in the carrier group.
[0063] Specifically, in the M downlink subframes of a carrier group corresponding to a carrier group in which UCI is ...
Example Embodiment
[0066] Embodiment two,
[0067] Power adjustment δ PUCCH is: in the M downlink subframes in a carrier group in which UCI is transmitted in the PUCCH on the uplink carrier, each power adjustment amount δ indicated by the PDCCH / EPDCCH received on any downlink carrier in the carrier PUCCH ; that is, when a PUCCH only feeds back the UCI of one carrier group, the δ received in the M downlink subframes in one carrier group PUCCH When summing, each downlink subframe only accumulates one δ indicated by one PDCCH / EPDCCH PUCCH , in each downlink subframe, the above-mentioned PDCCH / EPDCCH received on any downlink carrier in the carrier group can be selected for power accumulation, and δ can be obtained in each downlink subframe PUCCH The downlink carriers can be different. If the above PDCCH / EPDCCH is received on multiple downlink carriers in the carrier group in a downlink subframe, these PDCCH / EPDCCH should indicate the same δ PUCCH , and select one of them for summation.

Example Embodiment
[0070] Embodiment three,
[0071] Power adjustment δ PUCCH is: in the M downlink subframes of a carrier group in which UCI is transmitted in the PUCCH on the uplink carrier, each power adjustment amount δ indicated by the PDCCH / EPDCCH received on all downlink carriers in the carrier group PUCCH ; that is, when a PUCCH only feeds back the UCI of one carrier group, the δ received in the M downlink subframes in one carrier group PUCCH When summed, multiple δ indicated by multiple PDCCH / EPDCCH may be accumulated in each downlink subframe PUCCH , these PDCCH / EPDCCH are received on all downlink carriers in this subframe in this carrier group, the δ indicated by these PDCCH / EPDCCH PUCCH Not necessarily the same.
[0072] Specifically, the power corresponding to the TPC commands in the PDCCH / EPDCCH received on all downlink carriers of the carrier group in the M downlink subframes of a carrier group corresponding to UCI transmission in the PUCCH on the uplink carrier Adjustment δ ...
