摘要： The present disclosure provides a data packet transmission method and a device. The method includes: performing, by a transmit end device, channel coding on a to-be-sent data packet, and dividing the coded data packet into at least two data sub-packets; allocating a transmission resource to each data sub-packet; generating control information for each data sub-packet according to transmission resources of the at least two data sub-packets; and sending each data sub-packet and the control information of the data sub-packet on a corresponding transmission resource. A data packet and control information indicating a transmission resource of a data sub-packet are transmitted simultaneously, so that a receive end device can recognize multiple transmissions of a same data packet, and perform joint processing on multiple data sub-packets corresponding to the same data packet to obtain the sent data packet, and data packet transmission reliability is improved.

摘要： The present disclosure discloses a method and an apparatus for resource mapping and code division multiplexing. In the present disclosure, each cell selects a mapping scheme among at least two mapping schemes to implement resource mapping, which effectively reduces interference imposed on reference signal symbols of users at the edge of a cell; vector switching is performed for an orthogonal matrix to obtain multiple different codeword sequences and implement codeword design, so that a problem that the output power of reference signal symbols is unbalanced can be effectively alleviated.

摘要： A method, a base station and a user equipment for transmitting physical resource blocks and estimating channels are provided. The method includes: scheduling, by a base station, M PRBs for the user equipment, and configuring reference signal patterns for the M PRBs as following: allocating (X−1)M+1 demodulation reference signal subcarriers for M PRBs in a frequency domain, configuring only one demodulation reference signal subcarrier within a range of (−N, N] subcarriers in a border of every two PRBs, where locations of the rest (X−2)M+2 demodulation reference signal subcarriers keep consistent with locations of demodulation reference signal subcarriers in M contiguous first demodulation reference signal patterns in a frequency domain; and transmitting the configured M PRBs to the user equipment, so that the user equipment performs joint channel estimation according to the configured M PRBs. This saves reference signal overheads and optimizes data transmission rate.
