Abstract
In this paper, channel design for the New Radio (NR) physical uplink control channel (NR PUCCH) of 1 symbol (short-PUCCH) carrying up to 2 bits of acknowledgement (ACK)/negative ACK (NACK) is investigated. Two types of short-PUCCH designs, i.e., short-PUCCH type A and short-PUCCH type B, are compared and evaluated by computer simulation. In short-PUCCH type A, reference signal (RS) and ACK/NACK are multiplexed in different subcarriers within the same symbol; in short-PUCCH type B, no RS is used and ACK/NACK are indicated by which sequence is selected among the sequence candidates. The link-level evaluation results and link-budget analysis show that short-PUCCH type B has 40∼60 % larger coverage than short-PUCCH type A.
