UPLINK POWER CONTROL INFORMATION PROVIDING METHOD OF A BASE STATION AND UPLINK POWER CONTROL METHOD OF A TERMINAL CAPABLE OF CONTROLLING UPLINK TRANSMISSION POWER

摘要

PURPOSE: An uplink power control information providing method of a base station and uplink power control method of a terminal are provided to control uplink power using a minimum value obtained from the calculated path loss.;CONSTITUTION: A base station searches all transmission ends which are able to transmit a PDSCH(Physical Downlink Shared Channel) to a terminal(S301). The base station transmits CSI-RS(Channel Status Information-Reference Signal) configuration information and the CSI-RS transmission power information of the searched transmission end to the terminal(S302). The terminal calculates path loss using the reception power of the CSI-RS transmitted from the transmission end, the CSI-RS configuration information, and the CSI-RS transmission power information(S305). The terminal controls uplink power(S306).;COPYRIGHT KIPO 2013;[Reference numerals] (10) Terminal; (20) Base station; (S301) Transmission end allocation; (S302) CSI-RS configuration information and CSI-RS transmission power information; (S305) Path loss calculation; (S306) Uplink power control
