Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use a measurement procedure for beam detection within an existing cell. The UE perform a search procedure for a first synchronization signal block (SSB) to detect a first beam of a base station. The UE may determine a first timing offset for the first SSB based on the search procedure. The UE may estimate a second timing offset for a second SSB from the base station based on the first timing offset. The UE may perform a measurement procedure for the second SSB to detect a second beam of the base station based on the second timing offset. The UE may prune fake beams based on synchronization signals used for the measurement procedure.
