Group hopping enhancement for base sequences

Abstract:

Methods, systems, and devices for wireless communications are described. A network may generate a pool of distinct base sequences for use with uplink messages from a user equipment (UE) to a base station, where each base sequence in the pool of distinct base sequences may have a peak to average power ratio below a threshold. A base station may assign the pool of distinct base sequences into groups of base sequences based on a group size and a hopping pattern reuse factor. The base station may assign the groups of base sequences to cells and signal the group size and a hopping pattern index to UEs in the cells. A UE in a cell may identify the group of base sequences assigned to the cell based on the signaled parameters and select a base sequence for use in transmitting an uplink message to the base station.
