Method and device for indicating monitoring of uplink preemption information

Abstract

The invention provides a method and a device for indicating the monitoring of the uplink preemption information. The method comprises the following steps: a base station reserves URLLC time-frequencydomain resources for uplink URLLC services in each time slot of an uplink frequency band, and allocates the reserved URLLC time-frequency domain resources to uplink eMBB service users; the base station sends the downlink signaling carrying the monitoring indication bit to an eMBB service user, wherein the monitoring indication bit is used for indicating whether an eMBB service user needs to monitor uplink preemption information; and before sending the eMBB data, the eMBB service user determines whether to monitor uplink preemption information according to the monitoring indication bit. According to the invention, the blind detection frequency and power consumption of the eMBB service user in the whole system can be reduced, the resource utilization rate is effectively improved, and the spectrum efficiency and the energy efficiency are both considered.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for instructing monitoring of uplink preemption information. Background technique [0002] The International Telecommunication Union (ITU) has defined three main application scenarios for the fifth generation (5G) mobile communication system: enhanced Mobile Broadband (eMBB), such as 3D ultra-high-definition video; high-reliability and low-latency connection (Ultra -Reliable Low Latency Connection, URLLC), such as autonomous driving; large-scale machine type communication (massive Machine Type of Connection, mMTC), such as the Internet of Things, etc. Different scenarios have different latency and reliability requirements. For example, for a high-reliability and low-latency connection scenario, the control plane delay index is 10 milliseconds (ms), and the user plane delay index is 0.5 ms uplink and 0.5 ms downlink; the reliability perf...

Problems solved by technology

However, due to the unpredictability and low delay limitation of the URLLC service, more uplink time-frequency domain resources need to be reserved for the URLLC service users in the above method, which is easy to cause resource waste and lead to low resource utilization
