Problems solved by technology
[0003] However, in existing data transmission, multiple service data for the same user equipment are multiplexed together at the media access control (Media access control, MAC) layer, and data streams are not distinguished at the physical (Physical, PHY) layer. Therefore, different physical layer transmission technologies cannot be selected for multiple data streams of the same user equipment, resulting in the inability to make full use of spectrum resources, resulting in low transmission efficiency

The invention relates to a data transmission method and communication equipment. The communication device includes: a memory, a processor, and a communication interface; the memory is used to store mapping information of a data flow identifier and a physical layer transmission technology identifier; the processor is used to determine a scheduled data flow; according to the The data stream identification of the data stream determines the physical layer transmission technology identification corresponding to the data stream from the mapping information; different transmission blocks are generated for data streams corresponding to different physical layer transmission technology identifications, and each physical layer transmission technology identification Corresponding to a transmission block; processing the transmission block corresponding to the physical layer transmission technology identifier according to the physical layer transmission technology corresponding to the physical layer transmission technology identifier to generate wireless communication data; sending the received data to the receiving end through the communication interface wireless communication data.
Description
technical field [0001] The present invention relates to the technical field of communication, in particular to a data transmission method and communication equipment. Background technique [0002] With the development of wireless communication systems, uplink and downlink data transmission uses Single carrier frequency division multiple access (SC-FDMA) and Orthogonal frequency division multiplexing (OFDM) respectively. Improve wireless spectrum efficiency. The OFDM system has high requirements on frequency synchronization, and its performance is greatly affected by frequency offset and phase noise. Therefore, it is not applicable in some occasions, and other multi-carrier modulation techniques need to be considered. At the same time, with the diversification of data services, there are also different requirements for transmission. For example, some machine type communications (Machine type communications, MTC) services are sent periodically and the data volume is small, an...
