Abstract
A method of a user equipment (UE) in a wireless communication system supporting a shared spectrum channel access is provided. The method comprises: receiving, from a base station (BS), a set of higher layer parameters including a subcarrier spacing of a physical random access channel (PRACH) preamble, a logical root index (i) for the PRACH preamble, and an index (zeroCorrelationZoneConfg); determining a sequence length (L) for the PRACH preamble based on the subcarrier spacing of the PRACH preamble; determining a physical root index (i) for the PRACH preamble based on the logical root index (i); determining a cyclic shift (N) for the PRACH preamble based on the index (zeroCorrelationZoneConfg); generating the PRACH preamble based on the determined sequence length L, the determined physical root index i, and the determined cyclic shift N; and transmitting, to the base station (BS) over the shared spectrum channel, the PRACH preamble.
