Method for controlling uplink transmission power for transmitting a plurality of code words in a wireless communication system that supports a plurality of antennas, and apparatus for performing the method

摘要

The present invention relates to a terminal which controls uplink transmission power for transmitting a plurality of code words in a wireless communication system that supports a plurality of antennas, and a method in which the terminal performs the control. In a terminal which controls uplink transmission power for transmitting a plurality of code words in a wireless communication system that supports a plurality of antennas, a receiver receives, from a base station, an indicator that concerns the determination of the transmission power for each code word of the plurality of code words. A processor determines uplink transmission power for transmitting the plurality of code words on the basis of the indication value of the indicator. If the indication value is zero, the processor allocates the same uplink transmission power to each of the plurality of code words.

主权项

1. A method of controlling uplink transmission power for transmitting a plurality of codewords by a user equipment in a wireless communication system supportive of a plurality of antennas, the method comprising:
receiving an indicator regarding uplink transmission power determination per codeword for transmitting the plurality of codewords from an eNode B; and determining the uplink transmission power for transmitting the plurality of codewords based on an indication value of the indicator, wherein if the indicator indicates a first value, the uplink transmission power is determined such that a same uplink transmission power is assigned to each codeword, and wherein if the indicator indicates a second value, the uplink transmission power is determined such that an uplink transmission power of each codeword is assigned based on a size of transmission information of each codeword.
