    摘要: Apparatuses and methods for transmission and reception in a Closed-Loop (CL)-Multiple Input Multiple Output (MIMO) system are provided. A codebook generation method includes determining weight vectors vi(i=1, . . . ,2L) for a codebook V(4, 1, L), where Nt of a codebook V(Nt,s,L) denotes a number of antennas, s denotes a number of streams, and L denotes a number of codebook index bits, determining a unitary matrix Ti using an i-th vector vi of the codebook V(4, 1, L), and determining an i-th matrix of the codebook V(4, 2, L) by selecting a first column of the unitary matrix Ti as a first column of a weight matrix and selecting a column selected from other columns excluding the first column of the unitary matrix Ti in a particular pattern, as a second column of the weight matrix.

    摘要: A resource allocation method and apparatus in a communication system having backward compatibility are provided. In a transmission apparatus, a determiner determines a first frequency band for transmitting wireless resource allocation information to a terminal from among the frequency bands supporting the communication system, a MAP generator determines at least one second frequency band over which the terminal desires to receive a service and allocates wireless resources to the second frequency band, and a transmission unit transmits the wireless resource allocation information to the terminal over the first frequency band. In a reception apparatus, a reception unit receives wireless resource allocation information over a first frequency band determined by a base station and a MAP information decrypter determines at least one service frequency band included in the wireless resource allocation information. Accordingly, the method and apparatus dynamically allocate wireless resources to a terminal when multiple systems having backward compatibility coexist.

    摘要: An apparatus and method for transmitting and receiving data in a communication system are provided. In the method, a BS selects a repeater group from among a plurality of repeater groups, for use in transmitting first data to an MS and transmits the first data to the MS according to the number of repeaters of the selected repeater group. The first data is different from data transmitted by the repeaters of the selected repeater group.
