Claim of US Patent No. 10,560,902

1. A method for controlling uplink transmission power, comprising:receiving, by a User Equipment (UE), configuration information, and determining a power control (PC) parameter corresponding to a Transmission Time Interval (TTI) length of a first type and a PC parameter corresponding to a TTI length of a second type in accordance with the configuration information; and
determining, by the UE, transmission power of a channel which is transmitted using the TTI length of the first type in accordance with the PC parameter corresponding to the TTI length of the first type, and transmission power of a channel which is transmitted using the TTI length of the second type in accordance with the PC parameter corresponding to the TTI length of the second type,
wherein the receiving, by the UE, the configuration information, and determining the PC parameter corresponding to the TTI length of the first type and the PC parameter corresponding to the TTI length of the second type in accordance with the configuration information comprises one of,
receiving, by the UE, Radio Resource Control (RRC) signaling or broadcast signaling, acquiring at least one of a path loss compensation factor and a first power offset value corresponding to the TTI length of the first type, and acquiring at least one of a path loss compensation factor and a second power offset value corresponding to the TTI length of the second type, or
receiving, by the UE, a downlink control channel with a downlink Downlink Control information (DCI) format for scheduling a Physical Downlink Shared Channel (PDSCH) or a downlink control channel indicating downlink Semi-Persistent Scheduling (SPS) resource release, Acknowledgement/Non-Acknowledgement (ACK/NACK) feedback information of the PDSCH or the downlink control channel indicating the downlink SPS resource release being transmitted in a target PUCCH, and when a TTI length for the PDSCH or the downlink control channel indicating the downlink SPS resource release is the TTI length of the first type, taking, by the UE, a sum of a power adjustment value indicated by a TPC field in the downlink control channel with the downlink DCI format for scheduling the PDSCH or in the downlink control channel indicating the downlink SPS resource release and a power adjustment value corresponding to a previous PUCCH carrying the ACK/NACK feedback information of a PDSCH transmitted using TTI length of the first type or a downlink control channel indicating the downlink SPS resource release transmitted using the TTI length of the first type, as a power adjustment value for the PUCCH; and when the TTI length for the PDSCH or the downlink control channel indicating the downlink SPS resource release is the TTI length of the second type, taking, by the UE, a sum of the power adjustment value indicated by the TPC field in the downlink control channel with the downlink DCI format for scheduling the PDSCH or in the downlink control channel indicating the downlink SPS resource release and a power adjustment value corresponding to a previous PUCCH carrying the ACK/NACK feedback information of a PDSCH transmitted using the TTI length of the second type or a downlink control channel indicating the downlink SPS resource release transmitted using TTI length of the second type, as the power adjustment value for the PUSCH, or receiving, by the UE, a downlink control channel with a downlink DCI format for scheduling a PDSCH or a downlink control channel indicating downlink SPS resource release, the PDSCH or the downlink control channel indicating the downlink SPS resource release performing ACK/NACK feedback in a target PUCCH; when a TTI length for the PUCCH is the TTI length of the first type, taking a sum of a power adjustment value indicated by a TPC field in the downlink control channel with the downlink DCI format for scheduling the PDSCH or in the downlink control channel indicating the downlink SPS resource release and a power adjustment value corresponding to a previous PUCCH which is transmitted using the TTI length of the first type as a power adjustment value for the PUCCH; and
when the TTI length for the PUCCH is the TTI length of the second type, taking a sum of a power adjustment value indicated by a TPC field in the downlink control channel with the downlink DCI format for scheduling the PDSCH or in the downlink control channel indicating the downlink SPS resource release and a power adjustment value corresponding to a previous PUCCH which is transmitted using the TTI length of the second type as the power adjustment value for the PUSCH.
