    Abstract: A method for bit interleaving is provided. A method includes mapping a set of bits a≡{ak: k=0, 1, 2, . . . Npost−1} to an array B={Bi,j: i=0, 1, 2, . . . , M−1; j=0, 1, 2, . . . , N−1} such that bit ak maps to Bk mod M, └k/M┘, wherein mod denotes the modulo operator, └ ┘ denotes the floor operator, and M and N are constants, performing at least one of—a first permutation operation comprising permuting two or more bits within each of one or more first groups of bits, wherein each first group of bits is defined by G(1)p={Bi,p: i=0, 1, 2, . . . , M−1; p∈{0, 1, 2, . . . , N−1}} and—a second permutation operation comprising permuting two or more bits within each of one or more second groups of bits, wherein each second group of bits is defined by G(2)q={Bq,j: j=0, 1, 2, . . . , N−1; q∈ {0, 1, 2, . . . , M−1}} and de-mapping bits from B to obtain an interleaved set of bits b≡{bk: k=0, 1, 2, Npost−1} such that bit B,i,j is de-mapped to bit bNi+j.

    Abstract: A method for mapping cells onto symbols is provided. The cells include two or more cells processed by pre-coding in groups, the symbols include N symbols in a time-sequence, and each symbol includes M carriers in a frequency-order. The method comprises: mapping each cell to a carrier of a symbol; and frequency interleaving the carriers of each symbol. The mapping and the frequency interleaving are performed such that, following the frequency interleaving, the cells of a group of pre-coded cells are each mapped to carriers having the same carrier frequency or to carriers having carrier frequencies differing by no more than a threshold.

    Abstract translation: 提供了将单元映射到符号上的方法。 小区包括通过组中预编码处理的两个或更多个小区，符号包括时间序列中的N个符号，并且每个符号包括频率顺序的M个载波。 该方法包括：将每个小区映射到符号的载体; 并且对每个符号的载波进行频率交织。 执行映射和频率交织，使得在频率交织之后，将一组预编码小区的小区分别映射到具有相同载波频率的载波或具有不超过阈值的载波频率的载波。
