A method, in a first wireless terminal, for identifying channelization codes and modulation schemes for interfering signals targeted to neighboring wireless terminals, the method comprising: for each of one or more neighboring wireless terminals, reading (410; 510) corresponding downlink order data from a downlink control channel, the downlink order data specifying an assignment of one or more channelization codes and a modulation scheme for the corresponding neighboring wireless terminal, each assignment depending on the downlink order data and an unknown modulation configuration parameter previously sent to the corresponding neighboring wireless terminal, wherein the unknown modulation configuration parameter for each of the neighboring wireless terminals is a 64-QAM configuration parameter; identifying (420; 520) all possible combinations of channelization codes and modulation schemes for all of the neighboring wireless terminals, taking into account possible values for the unknown modulation configuration parameter and that no two wireless terminals are assigned the same channelization codes; for each possible combination, calculating (430; 530) a code-power consistency metric for each of the neighboring wireless terminals, based on despread data samples corresponding to the channelization codes of the possible combination, wherein calculating (430; 530) the code-power consistency metric comprises identifying a minimal set of channelization code groups, each channelization code group consisting of channelization codes that are not split between two more neighboring wireless terminals in any of the possible combinations, and using a distance function that compares average amplitudes or powers for each channelization code group for the neighboring wireless terminal to an average amplitude or power for all channelization code groups for the neighboring wireless terminal; for each possible combination, calculating (430; 540) a modulation-matching metric for each of the neighboring wireless terminals, based on received despread data samples corresponding to the channelization codes of the possible combination, wherein calculating (430; 540) the modulation-matching metric comprises comparing the despread data samples for the corresponding channelization codes to an assumed map of constellation points and calculating a fraction of the despread data samples that fall outside defined windows centered on each constellation point; and identifying (440; 550) a most likely one of the possible combinations, using a weighted sum of the code-power consistency metrics and the modulation-matching metrics for each possible combination. for each of one or more neighboring wireless terminals, reading (410;
