US 2026/0223180 A1 · PRACH SEQUENCE SET ALLOCATION FOR COVERAGE ENHANCEMENT

Abstract

The apparatus may be a wireless device configured to receive, from a network device, an indication of a plurality of preamble sequence sets for a random access procedure associated with the network device, where each preamble sequence set in the plurality of preamble sequence sets is associated with a different peak to average power ratio (PAPR) and transmit, based on one or more criteria for selecting a preamble sequence set, a random access message comprising a preamble sequence from a selected preamble sequence set of the plurality of preamble sequence sets. The apparatus may be a network device such as a base station configured to transmit, an indication of the plurality of preamble sequence sets and receive a random access message comprising a preamble sequence from a selected preamble sequence set of the plurality of preamble sequence sets.
