An uplink power control method, comprising: receiving, by user equipment, UE, power offset information configured by a network side device, wherein the power offset information is used to adjust a transmit power of the UE; and determining, by the UE, a transmit power of an uplink channel or an uplink signal based on the power offset information, wherein the receiving, by UE, power offset information configured by a network side device comprises: receiving, by the UE, an index of one of N power offset terms sent by the network side device, wherein N is a positive integer greater than or equal to 1,; wherein the receiving, by the UE, an index of any one of the N power offset terms sent by the network side device includes: receiving, by the UE, a TPC command field sent by the network side device, wherein the TPC command field is corresponding to an index of a power offset term and a TPC command, and determining, by the UE from the N power offset terms based on the TPC command field and the index of one of the N power offset terms, a power offset term corresponding to the TPC command field; wherein the determining, by the UE, a transmit power of an uplink channel or an uplink signal based on the power offset information comprises: determining, by the UE, the transmit power of the uplink channel or the uplink signal based on the determined power offset term. receiving, by user equipment, UE, power offset information configured by a network side device, wherein the power offset information is used to adjust a transmit power of the UE; and determining, by the UE, a transmit power of an uplink channel or an uplink signal based on the power offset information, wherein the receiving, by UE, power offset information configured by a network side device comprises: receiving, by the UE, an index of one of N power offset terms sent by the network side device, wherein N is a positive integer greater than or equal to 1,; wherein the receiving, by the UE, an index of any one of the N power offset terms sent by the network side device includes: receiving, by the UE, a TPC command field sent by the network side device, wherein the TPC command field is corresponding to an index of a power offset term and a TPC command, and determining, by the UE from the N power offset terms based on the TPC command field and the index of one of the N power offset terms, a power offset term corresponding to the TPC command field; wherein the determining, by the UE, a transmit power of an uplink channel or an uplink signal based on the power offset information comprises: determining, by the UE, the transmit power of the uplink channel or the uplink signal based on the determined power offset term. receiving, by the UE, a TPC command field sent by the network side device, wherein the TPC command field is corresponding to an index of a power offset term and a TPC command, and determining, by the UE from the N power offset terms based on the TPC command field and the index of one of the N power offset terms, a power offset term corresponding to the TPC command field; wherein the determining, by the UE, a transmit power of an uplink channel or an uplink signal based on the power offset information comprises: determining, by the UE, the transmit power of the uplink channel or the uplink signal based on the determined power offset term.
