Abstract: The present disclosure describes a downlink control information transmission method and apparatus. The method includes: determining multiple terminal devices used for downlink scheduling; determining downlink control information used by the multiple terminal devices to receive downlink data flows, where the downlink control information includes common control information shared by the multiple terminal devices, dedicated control information of each of the multiple terminal devices, and device identifier information of each terminal device, and an order of the device identifier information of each terminal device is the same as an order of the dedicated control information of each terminal device; and sending the downlink control information to the multiple terminal devices.

Abstract: The present invention provides a method for transmitting a downlink signal, a method for receiving a downlink signal, a network system and a terminal. The method includes: transmitting, by a control base station, a first group of downlink signal to a terminal; and transmitting, by a data base station, a second group of downlink signal to the terminal, the first group of downlink signal is at least partially different from the second group of downlink signal. The first group of downlink signal and the second group of downlink signal enable the terminal to implement a network function according to the first group of downlink signal and/or the second group of downlink signal. Embodiments of the present invention can improve network energy efficiency.
