1. A method for controlling uplink transmission in a mobile communication network by a transmission point, the method comprising:

  • generating, by the transmission point, first configuration information indicating frequency hopping to be newly applied to uplink transmission of a user equipment when a reception point to receive the uplink transmission of the user equipment is different from the transmission point performing a downlink transmission to the user equipment, wherein the first configuration information includes Physical Uplink Shared CHannel (PUSCH) hopping parameter sets configurable for the user equipment;

    transmitting, by the transmission point, a first signal including the first configuration information to the user equipment; and

    transmitting, by the transmission point to the user equipment, an uplink scheduling grant including information indicating, among the PUSCH hopping parameter sets, one set to be applied to a frequency hopping reconfiguration for the uplink transmission of the user equipment when a dynamic parameter set selection mode is activated in the user equipment,wherein the reception point receives, from the user equipment, a second signal to which a frequency hopping parameter selected based on the set indication information included in the uplink scheduling grant is applied; and

    wherein the dynamic parameter set selection mode is activated or deactivated by transmitting signaling for activating or deactivating the dynamic parameter set selection mode to the user equipment.
