METHOD AND APPARATUS FOR DESIGNING ACK/NACK CHANNEL IN WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for transmitting an acknowledgement/non-acknowledgement (ACK/NACK) by a base station (BS) in a wireless communication system, the method comprising:
- receiving uplink (UL) data from a UE;
mapping a resource for an ACK/NACK channel, which is used to transmit the ACK/NACK as a response to the UL data, to at least one control channel element (CCE) or at least one resource element group (REG); and
transmitting the ACK/NACK to the UE,wherein the ACK/NACK channel is multiplexed with a physical downlink control channel (PDCCH) in the at least one CCE or the at least one REG.

Abstract
A method and apparatus for transmitting an acknowledgement/non-acknowledgement (ACK/NACK) in a wireless communication system is provided. According to the present invention, an ACK/NACK channel, like a physical HARQ indicator channel (PHICH) in long-term evolution (LTE), is designed in a new radio access technology (NR) system. Specifically, a base station (BS) receives uplink (UL) data from a UE, maps a resource for an ACK/NACK channel, which is used to transmit the ACK/NACK as a response to the UL data, to at least one control channel element (CCE) or at least one resource element group (REG), and transmits the ACK/NACK to the UE. The ACK/NACK channel is multiplexed with a physical downlink control channel (PDCCH) in the at least one CCE or the at least one REG.

15. A base station (BS) in a wireless communication system, the BS comprising:
-
a memory; a transceiver; and a processor, operably coupled to the memory and the transceiver, that; controls the transceiver to receive uplink (UL) data from a UE; maps a resource for an acknowledgement/non-acknowledgement (ACK/NACK) channel, which is used to transmit the ACK/NACK as a response to the UL data, to at least one control channel element (CCE) or at least one resource element group (REG); and controls the transceiver to transmit the ACK/NACK to the UE, wherein the ACK/NACK channel is multiplexed with a physical downlink control channel (PDCCH) in the at least one CCE or the at least one REG.
