Problems solved by technology

[0004] From the above analysis, it can be seen that due to the uncertainty of the format, aggregation degree, and location of the control message during scheduling, the terminal needs to spend a lot of time and power on the blind detection of the control message (currently, the number of blind detections for a PDCCH is the highest Up to 44 times), for URLLC terminals, the delay and power consumption are unacceptable, so it is necessary to improve the PDCCH configuration and transmission and reception methods to reduce the processing time of URLLC terminals when receiving and demodulating PDCCH

Abstract

The invention provides a control information sending method and sending device, a control information receiving method and receiving device and communication equipment. The control information sendingmethod applied to a base station comprises the following steps: configuring first control information and second control information for a terminal; and sending first control information to the terminal according to a first period, and sending second control information to the terminal according to a second period, the first period being greater than or equal to the second period. By adopting thetechnical scheme of the invention, the configuration and the sending mode of the downlink control information are improved, and the processing time delay of the downlink control information at the terminal can be reduced, and the transmission efficiency of URLLC data service is improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to a control information sending method, a sending device, a control information receiving method, a receiving device, and a communication device. Background technique [0002] Currently, the research and development of the 5th generation mobile communication system (5G) is in full swing. According to future application requirements, the 5G system needs to support a variety of business scenarios. Among them, low-latency, high-reliability (Ultra-reliable and Low Latency Communications, URLLC) communication scenarios such as unmanned driving and industrial automation have attracted widespread attention. Usually, URLLC data is extremely bursty and has high requirements on delay, so this type of data has a very high resource scheduling priority. The current solution proposed for the transmission of URLLC data is: when the URLLC data arrives, the 5G base station im...
