Problems solved by technology

[0003] At present, in order to improve the reliability of the downlink control information (DCI) transmitted by the control channel, at the RAN 1#87 meeting, there were some preliminary discussions on the design of the control channel for the URLLC scenario, such as compressing the length of DCI, Allocate more resources for DCI to reduce the bit rate, etc., but the above method can only achieve a certain degree of reliability. When the reliability requirements are higher, the above method cannot meet

Abstract

The embodiment of the invention discloses a control information sending method, a base station, user equipment and a control information sending system. The method comprises the steps of determining control information of at least one piece of user equipment in N pieces of user equipment scheduled by a current sub-frame, wherein N is a positive integer; determining a first time frequency position and a second time frequency position occupied by the control information; and sending the control information of the first time frequency position to the at least one piece of user equipment by using a first type of beams, and sending the control information of the second time frequency position to the at least one piece of user equipment by using a second type of beams. With the application of the method provided by the invention, a successful receiving rate of a control channel can be improved, received signal quality of the control channel can be enhanced, and an error rate of the control channel can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for sending control information, a base station, user equipment and a system. Background technique [0002] With the commercialization of the fourth-generation mobile communication technology and the continuous growth of mobile services, research work on the fifth-generation communication technology (5th-Generation, 5G) has been started worldwide. 5G is a multi-technology fusion communication that meets the needs of a wide range of data and connection services through technological change and innovation. In the RAN71 meeting, the 3rd Generation Partnership Project (3GPP) established a research project on 5G new air interface research. According to 5G's division of vertical scenarios, 3GPP mainly conducts research on new air interface technology from three aspects: enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC) and ...
