Control information transmitting method and device and control information receiving method and device

Abstract

The embodiment of the invention provides a control information transmitting method and device and a control information receiving method and device. Resource fragmentation can be reduced and the transmission performance can be enhanced. The method comprises the steps that first equipment transmits first control information to second equipment, wherein the first control information includes the information of a first time frequency resource, the first time frequency resource at least bears the first data, and the first data include the first bit obtained by channel coding of the first information block; and the first equipment transmits second control information to the second equipment, wherein the second control information includes the information of a second time frequency resource, thesecond time frequency resource at least bears the second data, the second data include the second bit obtained by channel coding of the first information block, the second time frequency resource ispositioned in the preconfigured first resource area, the first resource area is used for bearing the first business and is not used for bearing the second business, and the first data and the second data belong to the data of the first business.

Description

technical field [0001] The embodiments of the present application relate to the field, and more specifically, to a method and device for sending control information and a method and device for receiving control information. Background technique [0002] Enhanced Mobile Broadband (eMBB for short), Ultra-Reliable and Low Latency Communication (URLLC for short), and Massive Machine Type Communication (mMTC for short), or According to the report, massive Internet of Things communication) is the three typical application scenarios in the fifth-generation (fifth-generation, referred to as "5G") communication in the future. [0003] The 5G communication system needs to support multiple services on the same carrier at the same time, and it needs to support multiple services to dynamically share spectrum resources. For example, URLLC services have high requirements on delay (for example, both uplink and downlink can be 0.5 milliseconds (ms)) and reliability (for example, the probabi...

Problems solved by technology

Moreover, some URLLC services are sporadic, and may occupy multiple blocks of resources discontinuously in one cycle

If resources are allocated for the eMBB data transmitted in the next cycle based on the resources occupied by URLLC services, it may cause resource fragmentation in the next cycle and affect the data transmission in the next cycle. challenges, while potentially having ongoing impacts on data transfer
