Method of transmitting and receiving acknowledgment signal in a wireless communication system

摘要

A method of receiving an acknowledgement (ACK) signal from at least one access terminal (AT) in a wireless communication system is disclosed. More specifically, the method includes transmitting at least one packet via a packet data channel from an access network (AN), receiving at least one ACK signal from the at least one AT using same channelization resources, wherein each AT is assigned a code specific to each AT, and identifying the ACK signal corresponding to the transmitted packet from the received at least one ACK signal.

1. A method of receiving a plurality of acknowledgement (ACK)/negative acknowledgement (NAK) signals at a base station (BS) in a wireless communication system utilizing an orthogonal frequency division multiplexing (OFDM) scheme, the method comprising:
transmitting, by the BS to a mobile station, a data packet; receiving, by the BS from the mobile station, each of a first ACK/NAK signal at a first time instance and a second ACK/NAK signal at a second time instance different from the first time instance for the same data packet, wherein the first ACK/NAK signal is spread on a first set of orthogonal frequency tones, wherein the second ACK/NAK signal is spread on a second set of orthogonal frequency tones, and wherein the first set of orthogonal frequency tones at the first time instance are different from the second set of orthogonal frequency tones at the second time instance.
