Abstract

The embodiment of the invention provides a control method for a BWP (BandWidth Part), related equipment and a system. The method comprises the step of: by sending DCI (Downlink Control Information) comprising target BWP information for activating or deactivating a target BWP for at least once, notifying UE (User Equipment) to activate or deactivate the information of the target BWP, so that the UEcan timely switch to the target BWP. Moreover, by sending the DCI for at least once, a probability that the UE misses inspection on the DCI comprising the target BWP information or falsely inspects the DCI comprising the target BWP information can be reduced, and a probability that the UE correctly switches to the target BWP can be improved.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a bandwidth part (bandwidth part, BWP) control method, related equipment and system. Background technique [0002] Future mobile communication systems (such as 5G systems) need to adapt to more diverse scenarios and business requirements. For example: including enhanced mobile broadband (Enhance Mobile Broadband, eMBB), ultra reliable and low latency communication (Ultra Reliable&Low Latency Communication, uRLLC), and massive machine type communication (massivemachine type of communication, mMTC, etc., these scenarios High reliability, low latency, large bandwidth and wide coverage are required for the system. In order to meet services with different needs and different application scenarios, the future mobile communication system may support multiple subcarrier spacings, and different subcarrier spacings may be applicable to different scenarios. The maximu...
