METHOD AND APPARATUS FOR CONTROLLING TPC COMMAND TIMING CONSIDERING TDD-FDD CARRIER AGGREGATION |
摘要 |
One or more exemplary embodiments provide a TPC command timing by taking into consideration TDD-FDD CA and cross-carrier scheduling, and provide a PUSCH transmission power controlling method in a subframe i for an FDD-based scheduled cell, based on the TPC command timing. According to one or more exemplary embodiments, an uplink transmission power may be effectively controlled when TDD-FDD CA and cross-carrier scheduling is configured for a UE. A Physical Uplink Shared Channel (PUSCH) transmission power control timing may be optimized. |

1. A User Equipment (UE) to receive a transmit power control (TPC) command in a wireless communication system supporting Time Division Duplex (TDD)-Frequency Division Duplex (FDD) Carrier Aggregation (CA), the UE comprising:
a processor to control a Radio Resource Control (RRC) connection with a base station through a first serving cell supporting a TDD mode, and to detect a Physical Downlink Control Channel (PDCCH) transmitted through the first serving cell, the PDCCH comprising a Transmit Power Control (TPC) command and being received in a subframe n−4; a receiver to receive an RRC message through the first serving cell, the RRC message comprising carrier aggregation (CA) configuration information, the CA configuration information comprising information of a second serving cell supporting an FDD mode, and the first serving cell and the second serving cell being aggregated by a TDD-FDD CA scheme; and a transmitter to transmit, from the UE, a Physical Uplink Shared Channel (PUSCH) associated with the TPC command through the second serving cell, the PUSCH being transmitted in a subframe n. |
