Sequence-based random access channel (RACH) occasion

A method of wireless communication performed by an apparatus of a network entity, comprising:

• transmitting configuration information associated with two or more overlapping random access channel (RACH) occasions,
• wherein the configuration information indicates preamble sequence sets for the two or more overlapping RACH occasions,
• wherein each of the two or more overlapping RACH occasions is associated with a respective preamble sequence set, and
• wherein the two or more overlapping RACH occasions overlap in time and frequency;
• and
• receiving a RACH preamble on a selected RACH occasion, of the two or more overlapping RACH occasions, in accordance with the respective preamble sequence set associated with the selected RACH occasion.

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

• a first interface configured to obtain configuration information associated with two or more overlapping random access channel (RACH) occasions,
• wherein the configuration information indicates preamble sequence sets for the two or more overlapping RACH occasions,
• wherein each of the two or more overlapping RACH occasions is associated with a respective preamble sequence set, and
• wherein the two or more overlapping RACH occasions overlap in time and frequency;
• a processing system configured to select a RACH occasion, of the two or more overlapping RACH occasions;
• and
• a second interface configured to output a RACH preamble for transmission on the selected RACH occasion in accordance with the respective preamble sequence set associated with the selected RACH occasion.
