Claim:
1. A method for facilitating maximizing a Euclidean distance for an acknowledgement (ACK) or a negative acknowledgement (NAK) transmission on an uplink, comprising: transmitting a packet to at least one device; receiving an ACK/NAK transmission from the at least one device in response to the packet, wherein the ACK/NAK transmission is encoded as a function of a size of the ACK/NAK transmission in number of bits and a modulation order to obtain a bit sequence, the bit sequence is scrambled based on the size of the ACK/NAK transmission and the modulation order to constrain a constellation size of the ACK/NAK transmission embedded in a data channel based on the size of the ACK/NAK transmission, and the size of the ACK/NAK transmission is less than the modulation order so that constellation points are chosen to correspond to edges of a constellation; and decoding the received ACK/NAK transmission to determine whether to retransmit the packet to the at least one device.
