Title: FREQUENCY HOPPING CONFIGURATION FOR A MULTI-TONE PHYSICAL RANDOM ACCESS CHANNEL TRANSMISSION
Abstract:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In one configuration, the apparatus may receive, from a base station, first information associated with one or more resources allocated for at least one PRACH transmission. In one aspect, the one or more resources may be allocated in an unlicensed spectrum. In another aspect, the one or more resources may be allocated based on a multi-tone PRACH bandwidth. The apparatus may also receive second information associated with a frequency hopping configuration from the base station. In one aspect, the frequency hopping configuration may be associated with at least one of the one or more allocated resources or the multi-tone PRACH bandwidth. The apparatus may transmit, to the base station, the at least one PRACH transmission using the one or more allocated resources within the multi-tone PRACH bandwidth and the frequency hopping configuration.
