Method for determining uplink control channel scheduling unit, base station and user equipment
摘要
說明書
In the NR system, a Physical Uplink Control Channel (PUCCH) is classified into two categories: a short PUCCH and a long PUCCH. The short PUCCH is mainly used for a user equipment (UE) in the central area of a cell to send timely an Acknowledgement/Negative Acknowledgement (ACK/NACK) feedback or other channel state information (Channel State Information, CSI). The short PUCCH is generally occupies several OFDM symbols located at the end of a slot (for example, 1 or 2 OFDM symbols at the end of a downlink slot; or 1 or 2 OFDM symbols at the end of an uplink slot), or several symbols placed before uplink data in the slot. The long PUCCH is mainly used for UE at the edge of a cell, and occupies more OFDM symbols to improve transmission coverage of the long uplink control channel. The long PUCCH generally includes 4 to 14 OFDM symbols, and is allowed to span multiple slots, and detailed implementation methods are still under discussion.
