Abstract
Methods, systems, and devices for in-channel narrowband (NB) companion air interface (CAI) assisted wideband (WB) random access channel (RACH) access. Periodic NB downlink (DL) synchronization sequences are detected. Range information is estimated by measuring the periodic NB DL synchronization sequences; and determining an NB CAI RACH occasion. The range information is transmitted to a gNode B (gNB), or other base station, in a NB CAI RACH procedure. At least one selected WB sequence based on the range information and at least one scheduled WB RACH occasion based on the NB CAI RACH occasion are received from the gNB. A contention free WB RACH procedure is performed based on the received at least one selected WB sequence and the at least one scheduled WB RACH occasion.
