A method, an apparatus, and a computer program product for sustaining a link with a wireless network are provided. The apparatus communicates data with the wireless network via a first link with a first base station, acquires a resource to perform a beam training sequence with a second base station, wherein the acquired resource allows the beam training sequence with the second base station to be performed while the data is communicated via the first link, performs the beam training sequence and exchanging signaling information with the second base station using the resource to establish a second link to the second base station, evaluates a link strength of the second link based on the beam training sequence, and determines whether to switch the data communication from the first link to the second link based on the evaluation.
