Title: METHODS OF TRANSMITTING AND DETECTING DOWNLINK CONTROL INFORMATION, DEVICE, BASE STATION, AND TERMINAL
Abstract:
The embodiments of the invention disclose methods of transmitting and detecting downlink control information, a device, a base station, and a terminal. The method of transmitting downlink control information comprises: a base station determines a group radio network temporary identifier of a user group to which a terminal belongs, performs, using the group radio network temporary identifier, cyclic redundancy check scrambling on group downlink control information of the user group to which the terminal belongs, and transmits, via a physical downlink control channel and to the terminal, the group downlink control information. The method of detecting downlink control information comprises: a terminal obtains a group radio network temporary identifier, performs, using the group radio network temporary identifier, blind detection on a search space in a physical downlink control channel, and obtains group downlink control information of a user group to which the terminal belongs. The embodiments of the invention also disclose a computer storage medium.
