Embodiment 2
[0090] In this embodiment, a resource indicating device is also provided, which is used to implement the above embodiments and preferred implementation modes, and what has been explained will not be repeated here. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.
[0091] figure 2 is a structural block diagram of a resource indication device according to an embodiment of the present invention, such as figure 2 As shown, the device includes:
[0092] The indication module 20 is configured to indicate, in the configured time-frequency resource area, the time-frequency resources occupied by the services of the first transmission time interval by the services of the second transmission time interval thr...
Embodiment 1
[0126] The base station transmits the PDSCH1 to the terminal A, and the transmission duration of the PDSCH1 is T1 (equivalent to the first transmission time interval in the above embodiment). In this embodiment, T1 is taken as an example of a time slot slot, including 14 OFDM symbols are not limited thereto, and T1 may also be other time units. During the PDSCH1 transmission, the base station transmits PDSCH2 to the terminal B again, and the PDSCH2 transmission time is T2 (equivalent to the second transmission time interval of the above-mentioned embodiment), T2<T1 or T2≤T1, in this embodiment, T2 is OFDM Or OFDM symbol group as an example, it is not limited thereto, T2 can also be other time units. Part or all of the resources used by the PDSCH2 are preempted by the PDSCH1, that is, the PDSCH1 is punctured for transmission. In the next slot, the base station notifies the terminal A of the puncturing instruction, that is, the PDSCH2 resource preemption instruction. The punch...
Embodiment 3
[0172] The base station transmits the PDSCH1 to the terminal A, and the transmission duration of the PDSCH1 is T1. In this embodiment, T1 is taken as an example of a time slot slot, including 14 OFDM symbols. It is not limited to this, and T1 can also be other time unit. During the PDSCH1 transmission, the base station transmits PDSCH2 to terminal B again, and the PDSCH2 transmission time is T2, T2<T1 or T2≤T1. In this embodiment, T2 is taken as an OFDM or OFDM symbol group as an example, and it is not limited thereto. T2 Other time units are also possible. Part or all of the resources used by the PDSCH2 are preempted by the PDSCH1, that is, the PDSCH1 is punctured for transmission. The base station notifies the terminal A of the puncturing instruction, that is, the PDSCH2 resource preemption instruction, in the slot satisfying the cycle C. That is, at this time, the puncturing instruction is sent once for every C slots, and the puncturing instruction mode of each indicating...

Abstract
The invention provides a resource indication method, a resource indication device and a storage medium. The method comprises the steps of: in a configured time-frequency resource area, indicating thetime-frequency resource of a service in the first transmission time interval preempted by a service in the second transmission time interval through physical layer signalling, wherein the first transmission time interval is greater than the second transmission time interval; the time-domain granularity and frequency-domain granularity determination mode of the time-frequency resource preempted bythe service in the second transmission time interval at least comprises one as follows: physical layer signalling indication or high-level signalling configuration; the time-domain granularity is determined through physical layer signalling indication or high-level signalling configuration; the frequency-domain granularity is determined through the determined time-domain granularity; the frequency-domain granularity is determined through physical layer signalling indication or high-level signalling configuration; and the time-domain granularity is determined through the determined frequency-domain granularity.
Description
technical field [0001] The present invention relates to the communication field, in particular, to a resource indication method and device, and a storage medium. Background technique [0002] Currently, the 4th 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 fifth generation mobile Communication technology (5G, the 5th Generation mobile communication technology) is facing more and more demands. Judging from the current development trend, both 4G and 5G systems are researching features that support enhanced mobile broadband, ultra-high reliability, ultra-low latency transmission, and massive connections. [0003] In order to support the characteristics of ultra-high reliability and ultra-low-latency transmission, it is necessary to transmit low-latency high-reliability services with a short tr...
