METHOD FOR TRANSMITTING UPLINK SIGNAL, USER EQUIPMENT, METHOD FOR RECEIVING UPLINK SIGNAL, AND BASE STATION

摘要

The present invention provides a method of transmitting an ACK/NACK (Acknowledgement/Negative ACK) signal for downlink data received from a base station to the base station by a user device included in a user device group including a plurality of user devices. According to the present invention, the base station semi-statically configures PUCCH (Physical Uplink Control Channel) resource identification information that is to be used by each of the plurality of user devices and dynamically assigns a collection of PUCCH resources available for ACK/NACK transmission of the user device group to the user device group. According to the present invention, a user device transmits the ACK/NACK signal to the base station using a PUCCH resource assigned to the user device among the collection of PUCCH resources dynamically assigned to the user device group based on the PUCCH resource identification information semi-statically assigned to the user device.
