Problems solved by technology

Therefore, it is impossible to realize the MCS table and corresponding MCS information flexibly selected by the network device for the terminal device by notifying the terminal device of the MCS table used by the semi-static method of high-level signaling. It can be seen that the current network device notifies the terminal device of the MCS information The method cannot adapt to the needs of URLLC business

Abstract

The invention relates to a communication method and device, which are used for enabling a mode of informing terminal equipment of selected modulation coding mode information to better adapt to the requirement of URLLC service. The communication method comprises the following steps: determining a modulation and coding mode index; determining first information; determining modulation coding mode information corresponding to the modulation coding mode index according to the first information; wherein the determination of the first information comprises: determining the first information accordingto the received DCI, or determining the first information according to the frequency of receiving the first HARQ response information in the first time window and/or the frequency of not receiving the first HARQ response information, the first HARQ response information being the first positive response information or the first negative response information.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] The International Telecommunication Union (ITU) has defined three major application scenarios for the fifth generation (5G) and future mobile communication systems: enhanced mobile broadband (eMBB), Ultra reliable and low latency communications (URLLC) and massive machine type communications (mMTC). [0003] Among them, the URLLC service has extremely high requirements on delay, and the one-way transmission delay from the sending end to the receiving end is required to be within 0.5 milliseconds (ms), and the transmission reliability of 99.999% can be achieved within 1 ms. [0004] At present, 5G new radio technology (new radio, NR) has been adopted. Compared with the block error rate (block error rate, BLER) of eMBB service is 0.1, URLCC can support modulation and coding with lower block error ...
