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

Embodiment Construction

[0097] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0098] With the development of communication technology and the new demand for wireless communication in daily life and industrial use that gradually appear in real life, the types of services that future communication systems can support will become more and more diverse. Some emerging services have significantly higher requirements on transmission delay than traditional services. For example, URLLC services have higher requirements on transmission delay than eMBB services.

[0099] figure 1 It is a schematic diagram of a communication system 100 applicable to the method and device for sending control information and the method and device for receiving control information according to the embodiments of the present application. Such as figure 1 As shown, the communication system 100 includes at least two communication devices, f...

Abstract

Embodiments of the present application provide a method and device for sending control information and a method and device for receiving control information, which can reduce resource fragmentation and improve transmission performance. The method includes: the first device sends first control information to the second device, the first control information includes information about a first time-frequency resource, the first time-frequency resource carries at least first data, and the first data includes first The first bit obtained by channel coding the information block; the first device sends second control information to the second device, where the second control information includes information about a second time-frequency resource, and the second time-frequency resource carries at least the second Two data, the second data includes the second bit obtained by channel coding the first information block, the second time-frequency resource is located in the pre-configured first resource area, and the first resource area is used to carry the first service but not For bearing the second service, the first data and the second data belong to the data of the first service.

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...
