METHOD AND DEVICE FOR TRANSMITTING UPLINK SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system. Particularly, the present invention relates to a method and a device by which a terminal controls uplink power in a wireless communication system, the method comprising the steps of: adjusting transmission power of one or more cells within a first cell group such that transmission power of the first cell group does not exceed a maximum power value set in the first group; adjusting transmission power of one or more cells within a second cell group such that transmission power of the second cell group does not exceed a maximum power value set in the second group; additionally reducing the transmission power of the first cell group and the second cell group if total transmission power of the whole cell group including the first cell group and the second cell group exceeds a maximum power value set in the terminal; and performing uplink transmission in the first cell group and the second cell group by using the additionally reduced transmission power.

主权项

1. A method of controlling uplink power, which is controlled by a user equipment in a wireless communication system, comprising the steps of:
adjusting transmit power of at least one or more cells belonging to a first cell group to make transmit power of the first cell group not exceed maximum power limit set to the first cell group; adjusting transmit power of at least one or more cells belonging to a second cell group to make transmit power of the second cell group not exceed maximum power limit set to the second cell group; if total transmit power of all cell groups containing the first cell group and the second cell group exceeds maximum power limit set to the user equipment, additionally reducing the transmit power of the first cell group and the transmit power of the second cell group; and performing uplink transmission in the first cell group and the second cell group using the additionally reduced transmit power.
