The method for a UE side thereof comprises: determining a TPC-RNTI corresponding to each carrier group and a tpc-index corresponding to each carrier group; detecting a PDCCH adopting a DCI format 3/3A and scrambled by using the TPC-RNTI corresponding to each carrier group in a common search space of a PCC; and according to the tpc-index corresponding to each carrier group, determining the position of an uplink power control command corresponding to the carrier group in the detected PDCCH scrambled by using the TPC-RNTI corresponding to the carrier group, and acquiring the uplink power control command corresponding to the carrier group from a corresponding position. Thus, a user equipment transmits a corresponding uplink power control command while supporting that uplink channels are transmitted over different uplink carriers corresponding to different carrier groups, thereby guaranteeing the normal and stable operation of a system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for obtaining uplink transmission power control commands from a identified location of a physical downlink control channel","description":"Disclosed are a method and apparatus for transmitting a power control command.
