US 2025/0220511 A1 · 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.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
receive, from a network entity, a configuration message that indicates a plurality of bandwidth parts and a first bandwidth part of the plurality of bandwidth parts is active for scheduling wireless communication between the UE and the network entity;
determine that a scheduling rate associated with the first bandwidth part fails to satisfy a scheduling threshold subsequent to detection of a shadowing event associated with the first bandwidth part or subsequent to a tune-away gap associated with the first bandwidth part;
decode a reference signal on a second bandwidth part of the plurality of bandwidth parts to determine that the second bandwidth part is active based at least in part on the scheduling rate associated with the first bandwidth part failing to satisfy the scheduling threshold;
and
monitor the second bandwidth part for a scheduling message based at least in part on decoding the reference signal on the second bandwidth part.
