    Abstract: A method for a partial interference alignment in a multi-antenna communication system includes, checking the number of access points (APs) operating at the same channel or adjacent channel; and calculating LIPs (Leakage Interference Power) that the respective APs have an effect on each base-station (STA). Further, the method includes choosing the upper three AP-STA pairs having the highest LIP in order as a candidate group for interference alignment; and performing a partial interference alignment on the candidate group for interference alignment.

    Abstract: An apparatus for grouping a plurality of stations in a multi-transmission environment includes an SNR (Signal to Noise Ratio) measuring unit configured to measure SNR values of the stations existing in the multi-transmission environment. Further, the apparatus includes a grouping unit configured to group the stations into several subgroups depending on the SNR values, wherein a leader is defined in each subgroup. Furthermore, the apparatus includes a control unit configured to determine an MCS (Modulation and Coding Scheme) intended for each subgroup and form different A-MPDU (Aggregated MAC Protocol Data Unit) for each subgroup separately to send to each subgroup in a multicast transmission.
