Title:
SIGNALING TECHNIQUES FOR BANDWIDTH PARTS
Document Type and Number:
WIPO Patent Application WO/2019/139835
Kind Code:
A1
Abstract:
Techniques are described herein for scheduling communication resources of a bandwidth part (BWP) after a BWP switching event when the frequency range of an active BWP is different than the frequency range of a target BWP. A user equipment (UE) may interpret the resource allocation field in scheduling downlink control information (DCI) that triggers a BWP switching event based on the active BWP. The UE and a base station may be configured to communicate using at least a portion of the resources of the active BWP in the first transmission opportunity after the BWP switching event. In subsequent transmitting opportunities where a scheduling DCI for the target BWP is received by the UE, the UE may interpret the resource allocation field of the new DCI as being based on the target BWP.
