When a User Equipment (UE) receives control information through a PDCCH, the received control information is set to be decoded in units of search spaces, each having a specific start position in the specific subframe. Here, a modulo operation according to a predetermined first constant value (D) is performed on an input value to calculate a first result value, and a modulo operation according to a predetermined first variable value (C) corresponding to the number of candidate start positions that can be used as the specific start position is performed on the calculated first result value to calculate a second result value and an index position corresponding to the second result value is used as the specific start position. Transmitting control information in this manner enables a plurality of UEs to efficiently receive PDCCHs without collisions.

Abstract: A resource allocation method and a method for transmitting resource allocation information in a mobile communication system are disclosed. That is, a LVRB (PRB) and a DVRB which are the units of a scheduling resource are defined and a resource allocation method and a method for transmitting resource allocation information using the same are disclosed. In the LVRB, a part bitmap scheduling method using a LVRB set is suggested and a method for constructing resource allocation information using the same is suggested. In the DVRB, a method for defining the DVRB using PRBs in a subframe is suggested and a method for constructing resource allocation information using the same when scheduling is performed using the DVRB constructed by the defined method is suggested. In order to prevent interference and collision from occurring due to the complete matching of the DVRBs in respective cells, a method using different DVRBs in the respective cells is suggested.

Abstract: A method for effectively transmitting/receiving a codeword in a MIMO system is disclosed. In a system including a plurality of predetermined rank structures, a reception end transmits rank information (RI), precoding matrix index (PMI), and channel quality information (CQI) of each codeword to a transmission end. The transmission end selects a rank structure on the basis of information received from the reception end. The transmission end selects only some codeword blocks among a plurality of codeword blocks available for the selected rank structure, transmits signals via the selected codeword blocks, and transmits a null signal for the non-selected codeword blocks.

Abstract: An STBC based signal transmission method considering the number of symbols within a slot. In transmitting a signal using two or more transmission antennas in a mobile communication system using a structure in which one subframe includes two slots and each slot includes a plurality of symbols, transmission symbols are paired in units of two consecutive symbols within each subframe by an STBC scheme. The transmission symbols are mapped to a frequency region in units of slots and the mapped transmission symbols are transmitted. One symbol within a slot in which the number of symbols excluding symbols for transmitting a reference signal is an odd number is not paired by the STBC scheme.
