Abstract

At present, for semi-persistent scheduling downlink data, only one bit of response information can be fed back in one time unit. However, the transmission period P of the semi-persistently scheduled downlink data becomes smaller and smaller, the situation that multi-bit response information needs to be fed back on one time unit may occur; based on this, the invention provides a communication method and device are mainly used for solving the problem of feeding back multi-bit response information on a time unit. The main principle is as follows: firstly, multi-bit response data to be sent on a time unit is determined, then N response codebooks are generated, the N response codebooks are used for bearing multi-bit response information, and finally, the N response codebooks are sent on the time unit.

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] Compared with previous generations of mobile communication systems, the fifth-generation (5th-generation, 5G) mobile communication systems have higher requirements in terms of transmission rate, delay, and power consumption. Among them, enhanced mobile broadband (eMBB), massive machine type communication (mMTC) and ultra-reliable and low-latency communication (URLLC) are defined as the three major aspects of future 5G. Large typical business, which points out the direction for the formulation of 5G standards. [0003] Among them, URLLC is one of the three typical services of 5G. The main application scenarios include unmanned driving, telemedicine, etc. These application scenarios put forward more stringent requirements in terms of reliability and delay. For example, the specific requirements of...
