Abstract
The present invention provides a resource indication method and device, and a storage medium. The method includes: in the configured time-frequency resource area, indicating through physical layer signaling that the service of the first transmission time interval is replaced by the service of the second transmission time interval For preempted time-frequency resources, the first transmission time interval is greater than the second transmission time interval, wherein the time-domain granularity and frequency-domain granularity determination method of the time-frequency resources preempted by the services of the second transmission time interval Including at least one of the following: indicated by physical layer signaling or high-layer signaling configuration; the time domaingranularity is determined by physical layer signaling indication or high-layer signaling configuration, and the frequency domain granularity is determined by the determined time domain granularity; The frequency domain granularity is determined through a physical layer signaling indication or high layer signaling configuration, and the time domain granularity is determined through the determined frequency domain granularity.
Description
Resource indication method and device, and storage medium technical field [0001] The present invention relates to the field of communications, and in particular, to a resource indication method and device, and a storage medium. Background technique Currently the fourth generation mobile communication technology (4G, the 4th Generation mobile communication technology) Long-Term Evolution (LTE, Long-Term Evolution) / Advanced Long-Term Evolution (LTE-Advance / LTE-A, Long‑Term Evolution Advance) and the 5th Generation mobile communication technology (5G, the 5th Generation mobile communication technology) is facing more and more demands. From the current development trend, both 4G and 5G systems are It is studying the features that support enhanced mobile broadband, ultra-high reliability, ultra-low latency transmission, and massive connections. In order to support the characteristics of ultra-high reliability and ultra-low-latency transmission, it is necessary to trans...
