Apparatus for transceiving signals in accordance with a frame structure supportive of a plurality of carriers in a wireless communication system and method thereof
Apparatus for transceiving signals in accordance with a frame structure supportive of a plurality of carriers in a wireless communication system and method thereof are disclosed. The method includes transceiving the signal using at least one carrier in accordance with the frame structure supportive of the carriers. The frame structure includes the carriers. First carrier among the carriers includes a downlink static assignment region assigned statically for a user equipment to receive the signal from a base station, a downlink dynamic assigned region assigned in a manner of being flexibly changed and an uplink transmitting region for the user equipment to transmit an uplink signal. Second carrier among the carriers includes an uplink transmitting region for the user equipment to transmit the uplink signal. The first or second carrier includes an uplink static assignment region assigned statically for an uplink transmission of the user equipment.
1. A method of transceiving signals by a user equipment in accordance with a frame structure of a cell in a wireless communication system, the method comprising:
transceiving the signals using a first carrier and a second carrier in accordance with the frame structure of the cell,

wherein the resource index of the dynamic downlink assignment region is changeable, and
wherein the second carrier comprises only the uplink assignment region;
receiving, from a base station, information including each maximum transmission power value corresponding to each resource block (RB) of a subframe of the uplink assignment region, each RB of the subframe having a different maximum transmission power value; and
transmitting a signal through the corresponding RB of the subframe of the uplink assignment region based on a transmission power value, the transmission power value being equal to or smaller than the maximum transmission power value of the corresponding RB.
