Systems, apparatus and methods for physical random access channel processing

A computer program product, comprising:

• a non-transitory computer-readable medium, comprising:
• a first set of codes for causing a computer to receive a signal indicative of a strong user and a desired user on a physical random access channel;
• a second set of codes for causing the computer to perform at least one of a single segment frequency domain detection or a multi-segment frequency domain detection on the signal indicative of a strong user and a desired user;
• a third set of codes for causing the computer to generate a residual signal by cancelling out the signal indicative of a strong user;
• and
• a fourth set of codes for causing the computer to obtain a message transmitted by a user equipment by performing at least one of the single segment frequency domain detection or multi-segment frequency domain detection on the residual signal.

An apparatus, comprising:

• means for receiving a signal indicative of a strong user and a desired user on a physical random access channel;
• means for performing at least one of a single segment frequency domain detection or a multi-segment frequency domain detection on the signal indicative of a strong user and a desired user;
• means for generating a residual signal by cancelling out the signal indicative of a strong user;
• and
• means for obtaining a message transmitted by a user equipment by performing at least one of the single segment frequency domain detection or multi-segment frequency domain detection on the residual signal.
