Timer based UE side beam sweeping for quick link blockage recovery

Abstract:

A base station may maintain multiple beam pair links, with one being actively used for communication. The active beam pair may become blocked. Accordingly, it may be necessary to switch to another beam pair. The apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a memory and at least one processor coupled to the memory. The at least one processor is configured to determine a set of active beam pairs including at least a first beam pair and a second beam pair and select the first beam pair. The at least one processor is also configured to predict that the first beam pair is blocked, the prediction based on an expiration of a timer and sweep through the set of active beam pairs based on predicting that the first beam pair is blocked.
