Problems solved by technology

[0004] In the existing LTE system, when receiving downlink data, it is necessary to blindly detect the control information in the control area first, and then receive the data through the control information. However, since the URLLC data and its control information are located in the data area of ​​the time-frequency resource, it cannot Use the downlink data receiving method in the existing LTE system to receive URLLC data

Abstract

An embodiment of the present invention provides a method for receiving URLLC data from a time-frequency resource, which is applied to a receiving device. The time-frequency resource includes eMBB data and URLLC data. The time-frequency resource also includes an OFDM symbol, and the OFDM symbol includes an Indicating the resource element RE, indicating that the RE indicates whether there is URLLC control information in the OFDM symbol, the method includes: when the indicating RE indicates that there is URLLC control information in the OFDM symbol, detecting the URLLC control information in the OFDM symbol, and according to the detected URLLC control information Receive URLLC data.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a method for receiving and sending data and a device for receiving and sending data. Background technique [0002] There are three application scenarios in the fifth generation mobile communication system (English: 5th generation mobile networks, referred to as: 5G): enhanced mobile broadband (English: enhanced Mobile BroadBand, referred to as: eMBB), high-reliability and low-latency communication (English: Ultra-Reliable Low Latency Communication, referred to as: URLLC) and large-scale Internet of Things communication (English: massive Machine Type Communication, referred to as: mMTC). Among them, the hole-punching multiplexing technology can realize time-frequency resource multiplexing of eMBB and URLLC, so as to use time-frequency resources more efficiently to transmit data. In a nutshell, the hole-punching multiplexing technology means th...
