Abstract

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.

Claims8

Dependent claims

A method of receiving an acknowledgement (ACK)/negative acknowledgement (NAK) signal at a base station (BS) in a wireless communication system using orthogonal frequency tones, the method comprising:

transmitting, by the BS, a data packet to a mobile station;
receiving, by the BS, a first ACK/NAK signal via a first set of orthogonal frequency tones from the mobile station;
and
receiving, by the BS, a second ACK/NAK signal via a second set of orthogonal frequency tones from the mobile station,
wherein the first ACK/NAK signal and the second ACK/NAK signal carry the same information and correspond to the data packet,
wherein the first set of orthogonal frequency tones and the second set of orthogonal frequency tones are shared between a plurality of mobile stations for ACK/NAK signal transmission by using a plurality of sequences corresponding to the plurality of mobile stations, and
wherein the first set of orthogonal frequency tones is different from the second set of orthogonal frequency tones over two transmission instants.
