摘要： A signal transmission method in a multiple antenna system is described. The signal transmission method includes, upon receiving channel state information from a receiving end, estimating a channel according to the channel state information, determining a precoding matrix according to the estimated channel and modifying the signal of the transmitting end using the precoding matrix in a process of mapping a symbol of the signal to a subcarrier, and transmitting the signal to the receiving end. According to the present invention, pre-equalization of a transmission signal can cause a receiving end to perform coherent combination, reduce pilot density by decreasing unnecessary pilots, and reduce interference within a cell or between cells.

摘要： A method for generating a set of at least two sequences is provided. This method selects at least one sequence from each of at least two sequences based on different lengths, including first and second types of sequences, and generates a set of at least two sequences using the selected sequences. Another method selects at least one sequence from a first type of sequences and at least one sequence from a second type of sequences generated by modulating the first type of sequences using a different type of sequences, and generates the set of at least two sequences using the selected sequences. To generate sequences based on a length corresponding to available subcarriers excluding a DC subcarrier, another method generates sequences such that the sequences are continuously arranged in a region excluding the DC subcarrier using frequency-domain cyclic shift while none of the sequences is allocated to the DC subcarrier.

摘要： A method for transmitting/receiving an additional control signal without any loss of bandwidth and power in an original Tx signal is disclosed. If the additional control signal is transmitted via the Tx signal composed of at least one of data and control signals, at least one of the amplitude and phase of the Tx signal of the time- and frequency-resource domain is modulated according to the additional control signal to be transmitted. The modulated Tx signal is transmitted to the receiver, so that the additional control signal can be transmitted irrespective of the original Tx signal. According to a modulation status of at least one of an amplitude and a phase of the Rx signal contained in the time- and frequency-resource domain, the additional control signal can be acquired.

摘要： A method for establishing RACH transmission to prepare against the frequency offset is disclosed. The method reduces the length of the RACH preamble even if the frequency offset exists, allows the RACH preamble to include a repeated structure (also called an iterative structure) or to use a specific sequence with less affect on the frequency offset, so that the Node-B can easily detect the RACH preamble. If different conditions are established in a high-speed UE and a low-speed UE, an amount of system overheads can be reduced as compared to another case in which an overall RACH condition has been prescribed for only the high-speed UE irrespective of the low-speed UE. And, the method determines whether the user equipment (UE) can estimate its speed according to the aforementioned RACH setup condition, and prescribes a detailed RACH access method according to the determined result.

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.
