Method for controlling uplink transmission in mobile communication network and apparatus therefor
First Claim
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.

Abstract
The present disclosure relates to a method for controlling uplink transmission and an apparatus therefor. The method for enabling a transmission point to control the uplink transmission in a mobile communication network, according to one embodiment of the present disclosure, includes the steps of: generating first configuration information for indicating a frequency hopping to be applied to the uplink transmission of a terminal; and transmitting, to the terminal, a first signal having the first configuration information, wherein a reception point is different from the transmission point, and the reception point receives a second signal to which the first configuration information is applied from the terminal.
