PUCCH Format 3
Long PUCCH Format without OCC
Long 4-14 symbol PUCCH carrying large UCI payloads (>2 bits) across multiple PRBs without time-domain orthogonal cover code.
Technical Explanation
PUCCH Format 3 spans 4 to 14 symbols across multiple PRBs (e.g. 1 to 16 PRBs). It is designed for large UCI payloads (tens to hundreds of bits, such as Type II CSI or massive CA HARQ-ACK) using DFT-s-OFDM transform precoding and frequency hopping without multiplexing multiple UEs via OCC.
Key Functions
- Transmits very large UCI payloads across wide coverage areas
- Utilizes DFT-s-OFDM for low Peak-to-Average Power Ratio (PAPR)
- Supports intra-slot and inter-slot frequency hopping
