Per-sample repetition of a random access preamble

A method for wireless communication at a network device, comprising:

• receiving a random access preamble from a user equipment (UE) via signaling that is associated at least in part with a sequence that comprises a second quantity of samples in a time domain, each sample included in a first quantity of samples in the time domain being repeated within the sequence, and repetitions of a same sample being consecutive within the sequence;
• generating a set of sequences associated at least in part with selecting sets of non-consecutive samples from the second quantity of samples in the sequence according to a sample interval, the sample interval equal to a quantity of times that each sample included in the first quantity of samples is repeated within the sequence;
• and
• detecting the random access preamble associated at least in part with a combination of two or more sequences included in the set of sequences.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• generate, for a random access preamble, a first sequence comprising a first quantity of time domain samples;
• repeat each time domain sample included in the first quantity of time domain samples to obtain, for the random access preamble, a second sequence comprising a second quantity of time domain samples that is greater than the first quantity of time domain samples, the second quantity of time domain samples including repetitions of the first quantity of time domain samples, and repetitions of a same time domain sample of the first quantity of time domain samples being consecutive within the second sequence;
• and
• transmit the random access preamble to a network device via signaling that is associated at least in part with the second sequence.
