METHOD FOR TRANSMITTING PHYSICAL LAYER DATA AND DATA TRANSMISSION DEVICE

摘要

Embodiments of the present invention provide a physical-layer data transmission method and a data transmission device, which can reduce limitations imposed by limited transmission bandwidth resources on transmission of physical-layer data inside a base station. The method includes: determining a target bit width of physical-layer data, where the target bit width is N bits; determining to-be-transmitted data whose bit width is N bits, where numerical values of all or some of bits in the to-be-transmitted data are numerical values extracted successively from a nonzero most significant bit to a less significant bit of the physical-layer data; and sending the to-be-transmitted data to a peer end. In the embodiments of the present invention, by performing bit width conversion on physical-layer data, a data rate is reduced, which can effectively reduce limitations imposed by limited transmission bandwidth resources on transmission of physical-layer data inside a base station, improve data transmission efficiency, and enhance user experience.
