Patent Description:
In a Long Term Evolution (LTE) system, the frequency domain resources of a terminal are allocated in an entire of a system bandwidth. In a <NUM>th Generation (<NUM>) New Radio (NR) system, because the system bandwidth is greatly increased, the transmission bandwidth of the terminal may only occupy a part of the system bandwidth.

In the current research of <NUM> NR, it has been decided to introduce the concept of a Bandwidth Part (BWP) to achieve frequency domain resource allocation in a smaller range than the system bandwidth. A base station may configure a plurality of BWPs through Radio Resource Control (RRC) signaling and then dynamically activate a BWP in Downlink Control Information (DCI). Each BWP is based on one numerology, wherein the numerology includes a subcarrier spacing and a Cyclic Prefix (CP). According to the current solution, only one BWP can be activated by a terminal, and when a new BWP is activated, the original BWP is deactivated.

As shown in <FIG>, when a BWP1 is in an activated state, if a BWP2 is activated, the BWP1 will be deactivated, and if the BWP1 is also deactivated, it will return to the default BWP.

Existing technical solutions cannot support simultaneous activation of a plurality of BWPs, therefore, simultaneous use of a plurality of numerologies cannot be supported, and the numerologies cannot be respectively optimized for different services when multiple types of services are transmitted in parallel. Furthermore, if switching is performed between two numerologies, it will also cause switching between two BWPs, thereby causing conversion of the radio frequency bandwidth of a terminal. The conversion of the radio frequency bandwidth will cause the terminal to be unable to receive or transmit data for a period of time, thereby causing waste of spectrum resources.

Related technologies can be found in <NPL>, <NPL>, <NPL>, and <NPL>.

In order to solve the above technical problems, the embodiments of the disclosure provide a resource configuration method and device, and a computer storage medium.

Any embodiment, implementation, example or aspect not claimed is only presented as information.

By adopting the technical solutions of the embodiments of the disclosure, a BWP configuration method that supports a plurality of numerologies is provided. The method can support transmission of signals by a terminal using a plurality of numerologies simultaneously, thereby it is possible to flexibly support simultaneous transmission of multiple types of services, and thus to improve the scheduling flexibility and spectrum utilization rate of the system.
