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.

摘要： A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

摘要： A method and a base station for receiving uplink control signals in a wireless communication system are described. The base station receives a first uplink control channel in a mixed resource block from a first user equipment. The mixed resource block includes a plurality of subcarriers. The base station receives a second uplink control channel in the mixed resource block from a second user equipment. The first uplink control channel is identified by a first cyclic shift value. The second uplink control channel is identified by a second cyclic shift value that is different from the first cyclic shift value. The first uplink control channel carries a Hybrid Automatic Repeat Request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) of the first user equipment. The second uplink control channel carries a channel quality indicator (CQI) for the second user equipment and a HARQ ACK/NACK of the second user equipment.

摘要： A method of allocating control information in a wireless communication system is provided. The method includes: allocating essential control information of a first system to a first sub-frame in a frame including a plurality of sub-frames each of which comprises a plurality of orthogonal frequency-division multiplexing (OFDM) symbols; and allocating essential control information of a second system to an nth sub-frame in a fixed position from the first sub-frame (where n is an integer satisfying n>1). Accordingly, in a frame supporting heterogeneous systems, essential control information can be fixedly allocated to a specific position while maintaining the number of system switching points, at which switching occurs between the systems, to one even if a radio resource allocation amount changes between the systems, and thus the essential control information that must be received by all user equipments can be effectively provided without the increase of overhead.
