Abstract

The invention provides a data transmission method and apparatus. According to the invention, a base station determines N physical shared channels for downlink control channel dispatching wherein the N physical shared channels are provided with different coverage enhancement levels and/or repeated transmission times and N is an integer greater than one. The base sends the downlink control channel, and the downlink control channel carries the dispatching information for the N physical shared channels. As one downlink control channel carries dispatching information of the physical shared channels with different coverage enhancement levels and/or repeated transmission times, the physical shared channels with different repeated times are sent independently so as to avoid resource conflict incurred in data transmission from downlink control channel dispatching.
