Abstract

The invention discloses a control channel design method, one of which includes: setting one or more control indications (SCIs) in the superframe according to the scheduling of the base station, wherein each SCI controls a subframe scheduled by the base station this time or is determined by A subframe area composed of multiple subframes, and the SCI carries control information, and the control information is used to control and indicate the mapping symbols; wherein, the position of the SCI in the superframe is fixed; according to the control information in the SCI, the subframe controlled by the SCI One or more mapping symbols are set in the frame or subframe area, and the mapping symbols are used to indicate resource allocation of one or more subframes. Through the above technical solution, the technical advantages of the subframe can be fully utilized, the data transmission delay can be reduced, and the spectral efficiency of the system can be improved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to control channel design methods. Background technique [0002] In a wireless communication system, a base station refers to a device that provides services to a terminal. The base station communicates with the terminal through an uplink / downlink link. The downlink refers to the direction from the base station to the terminal, and the uplink refers to the direction from the terminal to the base station. Multiple terminals can simultaneously send data to the base station through the uplink, and can also receive data from the base station through the downlink at the same time. [0003] In a wireless communication system that uses a base station to implement wireless resource scheduling control, the scheduling and allocation of system wireless resources is completed by the base station, for example, the base station provides resource allocation information when the base stat...
