Abstract

Technology described herein relates to systems, methods, and computer readable media to enable a millimeter wave capable small cell (MCSC) devices to receive a handover of a user equipment from a universal mobile telecommunications system terrestrial radio access node B (eNB). In particular, systems and methods are described for user equipment (UE) association with a MCSC operating as a booster for an eNB in a time division duplexing (TDD) system, including identification of and communication on preferred cell sector between the UE and the MCSC. Protocols for concurrently performing a beam search and time and frequency synchronization for downlink communication are also described. Several sub-frame designs to facilitate these protocols are also described.
