    Abstract: Provided is a data transmission method and device. The method includes: receiving IQ data from an uplink; according to the mapping of the IQ data in a Common Public Radio Interface (CPRI) basic frame, utilizing at least one storage unit to sequence the IQ data; combining a control word with the sequenced IQ data to form CPRI data, and transmitting the CPRI data. The solution utilizes at least one storage unit to sequence the IQ data, and extracts the sequenced data for a CPRI framing operation.

    Abstract: A method and device for sequencing the ZC sequences of the RACH. According to the CM of OPSK, ZC sequences of the RACH are divided into low CM group and high CM group, to make the index of each ZC sequence within the low CM group smaller or larger than the index of each ZC sequence within the high CM group. The ZC sequences within the low CM group and within the high CM group are respectively divided into S sub-groups using S−1 maximum cyclic shift thresholds. The sequences are sequenced within each sub-group, to make the ZC sequences in adjacent sub-groups within the low CM group and within the high CM group have different sequencing and the ZC sequences in adjacent sub-groups between the low CM group and the high CM group have the same sequencing.
