1. A method comprising:

  • allowing, by a wireless terminal, a maximum number of HARQ transmissions for a first packet, wherein the maximum number is not an integer multiple of a number of interlace offsets;

    recovering, by the wireless terminal, from possible feedback errors when a negative acknowledgement (NAK) is mistakenly received by a base station for a positive acknowledgement (ACK) or when an ACK is mistakenly received by a base station for a NAK; and

    determining, by the wireless terminal, that a second packet is being transmitted instead of the first packet based on the wireless terminal receiving more retransmissions for the first packet than is allowed.
