AI Technical Summary

Problems solved by technology

However, in order to ensure the flexibility of resource scheduling, the control information in the prior art provides the possibility of multiple resource scheduling, so the number of bits occupied by the control information is relatively large
In the process of transmitting the control information of the URLLC service, if the control information occupies a large number of bits, the transmission error probability will increase, which will lead to an increase in the number of retransmissions, thus affecting the reliability of the URLLC service

Abstract

A method and device for transmitting control information, which can improve the reliability of transmitting control information, including: generating control information, the control information includes scheduling information of terminal equipment and first identification information, and the first identification information is the identification information of the terminal equipment Part of the identification information; send control information to the terminal device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for transmitting control information. Background technique [0002] With the development of communication technology, the future 5G communication system will be committed to supporting higher system performance, which will support a variety of business types. For example, the above-mentioned multiple service types include enhanced Mobile Broadband (eMBB for short), Massive Machine Type Communication (mMTC for short), Ultra-reliable and low latency communications (Ultra-reliable and low latency communications, Abbreviation: URLLC), Multimedia Broadcast Multicast Service (Multimedia Broadcast Multicast Service, abbreviation: MBMS), positioning service, and so on. [0003] A major feature of the 5G communication system compared to the 4G communication system is the added support for URLLC. URLLC's services include many types, and typical use cases include indu...
