摘要
The invention includes various embodiments for use in physical layer processing. One embodiment determines the address mapping of bits in the physical channel buffer from the address of bits in the first interleaver buffer (82). The physical channel buffer addresses (84) are determined corresponding to addresses of the bits after rate matching (88), bit scrambling (90), second interleaving (92) and physical channel mapping (94). The bits are directly read (78) from the first interleaver buffer (82) and written to the physical channel buffer (84) using the determined physical channel buffer addresses. Another embodiment determines the address mapping of bits in the first interleaver buffer (82) from the address of bits in the physical channel buffer (84). The first interleaver buffer addresses are determined corresponding to addresses of the bits after reverse rate matching (88), reverse bit scrambling (90), reverse second interleaving (92) and reverse physical channel mapping (94). The bits are directly read from the determined first interleaver buffer addresses (82) and written to the physical channel buffer addresses (84).
