Problems solved by technology

[0004] In some cases, it is necessary to switch the BWP of the terminal. Since the Numerology corresponding to each BWP may be different, the length of the corresponding time slot (slot) will also be different accordingly. When the uplink BWP of the terminal needs to be switched, the uplink transmission that needs to be scheduled in advance , including uplink data transmission and Hybrid Automatic RepeatreQuest (HARQ) feedback for downlink data. During the BWP switching process, the slot length changes will cause ambiguity, resulting in the terminal being unable to send at the correct time.

Abstract

The invention provides a resource scheduling method, a base station and a terminal. The resource scheduling method applied to the base station comprises the following steps: sending first DCI to the terminal, wherein the first DCI comprises a first indication domain, and the first indication domain is used for indicating a BWP for transmitting the scheduled information. Consequently, the terminalcan receive or send the scheduled information on the BWP indicated by the first DCI, and the terminal is guaranteed to receive and send the scheduled information at correct time.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource scheduling method, a base station and a terminal. Background technique [0002] Compared with previous mobile communication systems, future mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of New Radio (NR for short) include Enhanced Mobile Broadband (eMBB for short), Ultra Reliable&Low Latency Communication (URLLC for short), Massive IoT communication (Massive Machine Type Communication (mMTC for short), these scenarios put forward requirements for the system such as high reliability, low latency, large bandwidth, and wide coverage. In order to meet different needs of services and different application scenarios, the subcarrier spacing of the NR system is no longer a single 15kHz like in Long Term Evolution (LTE). The NR system can support multiple subcarrier spacings. Different ...
