Bandwidth part switching based on reference signal decoding

Abstract

Methods, systems, and devices for wireless communication are described. A network entity may configure a user equipment (UE) supporting multiple subscriptions with a set of bandwidth parts (BWPs), where a first BWP may be active. The UE may detect a shadowing event or a tune-away gap associated with the first BWP. Subsequently, the UE may identify a decline in a scheduling rate or channel conditions associated with the first BWP. The UE may no longer receive downlink control information (DCI) from the network entity during the shadowing event or the tune-away gap, and thus may be unaware of a BWP switch command from the network entity. Accordingly, the UE may decode a reference signal on a second BWP to determine whether the second BWP is active (therefore indicating that the network entity did command a BWP switch). The UE may switch and monitor the second BWP for a scheduling message.
