Abstract
Briefly, in accordance with one or more embodiments, an apparatus of a user equipment (UE) comprises baseband circuitry including one or more processors to decode a secondary synchronization signal (SSS) or a beam reference signal (BRS) received from an evolved Node B (eNB) to select a Tier-1 sector for receiving downlink transmissions from the eNB, decode a downlink control channel message received from the eNB at one or more fixed time offsets after the UE decodes the SSS to obtain index information for the Tier-1 sector to identify the Tier-1 sector, and if the Tier-1 sector has changed initiate a random access procedure to select an updated Tier-1 sector, and generate an updated Tier-1 sector index message to report to the eNB.
