Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may be configured to transition to communicating on a first bandwidth part from communicating on a second bandwidth part. In order to ensure that the UE is able to perform receiver processing for demodulating data received on the first bandwidth part, after transitioning to communicating on the first bandwidth part, the UE may be configured to perform receiver processing using reference signals received on the second bandwidth part. That is, for a configured period of time, before the UE is able to perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the first bandwidth part, the UE may perform receiver processing for demodulating data received on the first bandwidth part using reference signals received on the second bandwidth part.
