    摘要: There are provided a method and apparatus for allocating a sounding channel in a wireless communication system. A base station transmits a first sounding channel allocation data to allocate a first sounding channel for a first system to a first zone, and transmits a second sounding channel allocation data to allocate a second sounding channel for a second system other than the first system to a second zone. The first zone and the second zone are multiplexed by an FDM (Frequency Division Multiplexing) method, and the first sounding channel and the second sounding channel are allocated to a same OFDMA (Orthogonal Frequency Division Multiple Access) symbol. A channel response can be estimated accurately when a terminal for IEEE (Institute of Electrical and Electronics Engineers) 802.16m system and a terminal for IEEE 802.16e system coexist in a legacy support mode.

    摘要: A method for configurating a basic signal allocation unit and a method of transmitting signals using the configurated basic signal allocation unit are disclosed. In particular, a basic frequency domain signal allocation unit is configurated by considering at least one selected from the group consisting of a signaling overhead, a size of a coherent bandwidth and a number of divisors among specific numbers and an OFDM symbol number corresponding to a multiple of a subframe unit, each of the specific numbers multiplied to a predetermined subcarrier spacing to enable a result value of the multiplication to have a difference smaller than a prescribed threshold from a divisor of a system bandwidth. And, a time domain unit is configurated by 1-subframe unit. Accordingly, signaling overhead can be efficiently reduced.

    摘要: Disclosed are an apparatus and a method for performing communication using a half-frequency division duplex (H-FDD) frame structure in a mobile communication system. A user equipment for performing communication using an H-FDD frame structure according to the present invention comprises an RF unit in which each user equipment group receives and transmits signals using the H-FDD frame structure wherein the order of the downlink zone and uplink zone are reversely allocated to each of the groups. The downlink zone and uplink zone, which are allocated to each of the user equipment groups in the H-FDD frame structure, include a sub-frame wherein one or more symbols are allocated to idle time slots or are punctured. Each of the user equipment groups can receive and transmit signals using symbols that are not allocated to the idle time slots or are not punctured in the sub-frame.
