    摘要： Provided is an uplink transmission power control method in a wireless communication system. Said method includes preferentially determining the transmission power of an uplink control channel, and determining the transmission power of an uplink data channel within the difference between the maximum transmittable power of a terminal and the transmission power of the uplink control channel, wherein the transmission of the uplink control signal through the uplink control channel and the transmission of the uplink data through the uplink data channel are performed at the same time using wireless resources different from one another. The present invention preferentially allocates the transmission power required for the transmission of an uplink control channel, and allocates residual power to an uplink data channel, thereby improving the effectiveness of power allocation when an uplink control signal and an uplink data signal are transmitted at the same time using physical resources different from one another.

    摘要： A method of allocating a radio resource in a frequency division duplex (FDD) frame in which a downlink frame and an uplink frame are divided in a frequency domain in a wireless communication system includes allocating a downlink resource region for a first system in the downlink frame, and allocating an uplink resource region for the first system to the uplink frame such that the uplink resource region does not temporally overlap with the downlink resource region for the first system, wherein a resource region except for the downlink resource region for the first system is allocated to a downlink resource region for a second system in the downlink frame, and a resource region except for the uplink resource region for the first system is allocated to an uplink resource region for the second system in the uplink frame. When a half-duplex FDD (H-FDD)-type user equipment is supported in a frequency division duplex (FDD) frame supporting heterogeneous systems, radio resources can be effectively utilized by minimizing waste of unnecessary radio resources.

    摘要： A method for establishing a cyclic shift sequence to provide against the frequency offset is disclosed. The method calculates a distance between a channel response position of the sequence and an alias channel response position caused by a frequency offset, calculates the number of cyclic shifts per group according to the calculated distance, and establishes the cyclic shift (CS)-applying interval. This method easily establishes a cyclic shift (CS) interval at a specific location having no overlapping by considering a channel response of a reception (Rx) sequence and an alias location of this reception (Rx) sequence, although a reception (Rx) signal is shifted by a channel delay spreading or a propagation delay irrespective of categories of a domain generating a sequence, so that it can greatly reduce the number of the detection errors and the false alarm rate. And, if a sequence of the cyclic shift (CS) is allocated to a cell having a frequency offset of more than a predetermined level, the present invention can minimize the influence of a frequency offset on a high-mobility cell.
