Abstract
A method and a device for communication based on LAA, the method for communication includes: transmitting cell group information to a terminal, where the cell group information points to multiple carriers, and the multiple carriers comprise an un-licensed carrier and a licensed carrier; and transmitting downlink control information through an activated carrier in the multiple carriers, where the cell group information is used to instruct the terminal to implement a blind detection to the multiple carriers so as to obtain the downlink control information. Technical solutions of the present disclosures can improve communication speed and efficiency of a LAA system.
Claims22
A method for communication based on LAA (License Assisted Access), comprising:
- transmitting cell group information to a terminal, where the cell group information points to multiple carriers, and the multiple carriers comprise an un-licensed carrier and a licensed carrier;
- and
- transmitting downlink control information through an activated carrier in the multiple carriers, where the cell group information is used to instruct the terminal to implement a blind detection to the multiple carriers so as to obtain the downlink control information.
A method for communication based on LAA (License Assisted Access), comprising:
- receiving cell group information from a base station, where the cell group information points to multiple carriers, and the multiple carriers comprise an un-licensed carrier and a licensed carrier;
- and
- implementing a blind detection to the multiple carriers based on the cell group information so as to obtain downlink control information.
A device for communication based on LAA (License Assisted Access), comprising:
