ith minimum code rate of 1/4 and the encoded bits are repeated to improve the robustness of Assignment A-MAP information transmission. The Assignment A-MAP IEs may encoded with two different effective code rates, i.e., code rate sets (1/2, 1/4) or (1/2, 1/8), where indication is signaled via the superframe header. Note that each code rate set consists of two code rates where the first code rate is applied to the first group of Assignment A-MAP IEs within the control region and the second code rate is applied to the second group of Assignment A-MAP IEs within the control region. The number of Assignment A-MAPs in each group is indicated through parameter Assignment A-MAP Size in non-user-specific A-MAP. This would allow grouping of the users depending on their channel conditions and geographical location (e.g., near or far to the BS), and ensure robustness of the Assignment A-MAP IE transmission to each user group. If FFR is used, the above code rates can be used in reuse-1 partition. The 1/2 or 1/4 code rate is used in the power-boosted reuse-3 partition. The encoded bit sequences are modulated using QPSK baseband modulation scheme. In most cases, the MS needs to decode all MLRUs in an A-MAP region in order to determine whether there is any relevant assignment A-MAP. The MS does not need to use different MCS to decode the same MLRU. The non-user-specific A-MAP carries information about the MCS used by each MLRU. The MS does not need to decode the MLRU using different rate de-matching for different IE sizes. All assignment A-MAP IEs or segmented IEs have fixed sizes, i.e., 56 bits. The MS deter- mines if an assignment A-MAP is relevant by performing a CRC test using its STID (for unicast assignments), group ID (for group scheduling), or RAID (CDMA allocation) to unmask the CRC. If the CRC test is successful, the MS may continue parsing the content of the decoded Assignment A-MAP. As mentioned earlier in this section, there are four lookup tables, each with 256 entries, which are used to signal the assignment A-MAP
