Sequence design and resource allocation for NR PUCCH

Abstract:

A user equipment (UE) can include processing circuitry configured to decode physical uplink control channel (PUCCH) configuration information received from a Next Generation Node-B (gNB). The configuration information includes a cell-specific base sequence hopping pattern. A PUCCH base sequence is selected from a plurality of available PUCCH base sequences based on the cell-specific base sequence hopping pattern and UCI information. A cyclic shift is applied to the PUCCH base sequence to generate a cyclically shifted PUCCH sequence. The cyclically shifted PUCCH sequence is encoded for transmission to the gNB using a PUCCH physical resource. The cyclically shifted PUCCH sequence carries the UCI and is code division multiplexed (CDM) with at least another cyclically shifted PUCCH sequence within the PUCCH physical resource.
