Abstract: Apparatus and methods for multi-cell broadcast access channel utilization in a wireless network. In one embodiment, the apparatus and methods provide random access channel (RACH) procedure for a 3GPP-compliant user device (e.g., an enhanced UE or UEe) which attempts to connect to multiple cells simultaneously. In one variant, the UEe employs a multi-step (e.g., 4-step) RACH procedure to connect to the multiple cells. This significantly increases the likelihood of RACH procedure success and UEe access. In another variant, a 2-step RACH process is utilized. Variants of the apparatus and methods utilizing unlicensed spectrum and LBT (listen-before-talk) protocols are also described.
