Narrow band physical random access channel frequency hopping patterns and detection schemes

An apparatus for wireless communication, comprising:

• means for identifying a physical random access channel (PRACH) for communication between a base station and a user equipment (UE), the PRACH comprising a plurality of subcarriers;
• and
• means for determining a frequency hopping pattern within the PRACH for a random access preamble comprising a plurality of single tone transmissions, the frequency hopping pattern comprising a plurality of frequency hops across the plurality of subcarriers, at least one frequency hop of the plurality of frequency hops being associated with a pseudo-random frequency hop distance.

A non-transitory computer readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:

• identify a physical random access channel (PRACH) for communication between a base station and a user equipment (UE), the PRACH comprising a plurality of subcarriers;
• and
• determine a frequency hopping pattern within the PRACH for a random access preamble comprising a plurality of single tone transmissions, the frequency hopping pattern comprising a plurality of frequency hops across the plurality of subcarriers, at least one frequency hop of the plurality of frequency hops being associated with a pseudo-random frequency hop distance.
