    摘要: A random access method based on priority is disclosed. A priority-based random access method for use in a random access method supporting emergency communication including selecting, by a user equipment (UE), a random access slot corresponding to priority of the UE, among several random access slots to which at least two priorities are allocated, selecting an arbitrary sequence by the UE, and transferring the selected sequence to a base station via the selected random access slot. The method minimizes a UE access delay time requesting emergency communication by assigning priority to resources, and is able to reduce an amount of wasted resources by effectively distributing resources to not only a high-priority UE but also a low-priority UE according to individual situations.

    摘要: An adaptive resource partitioning method includes: selecting a predefined pattern-based partitioning method or an informed map-based partitioning method according to the number of channels used for resource allocation, data characteristics, and a channel environment variation, if the predefined pattern scheme is selected, selecting any of predefined patterns, partitioning distributed and localized resource allocation areas according to the selected pattern, and transmitting a pattern index of the selected pattern to a terminal, and if the informed map scheme is selected, partitioning distributed and localized resource allocation areas according to an arbitrary pattern, and transmitting bitmap control information indicating information of the partitioned areas to the terminal. So, it effectively obtains a diversity and a scheduling gain when distributed and localized resource allocations are simultaneously used, such that it increases flexibility of resource allocation, increases an available data transfer rate, and reduces an amount of necessary control information.

    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.
