Access point and interference control method

摘要

In MU-MIMO communication in which an AP (access points: wireless base station) receives signals sent from plural terminals at the same time and at the same frequency, combinations of terminal users and decoding order of the received signals are determined so that interference reduction advantage by applying SIC can be effectively obtained. The access point includes: a plurality of antennas; and a scheduler used for performing the MU-MIMO communication with a plurality of terminals at the same time and at the same frequency. The scheduler is configured to determine the combinations of the terminal users on the basis of uplink communication quality information of the plurality of the terminals when the MU-MIMO communication is performed, and to send the determined combinations of the users as schedule information.

1. An AP (access point: wireless base station), comprising:
a plurality of antennas; a scheduler used for performing uplink MU-MIMO communication with a plurality of terminals at the same time and at the same frequency; and a MIMO decoder configured to utilize SIC (Successive Interference Cancellation), wherein the scheduler is configured to determine combinations of the terminal users on a basis of uplink communication quality information of the plurality of the terminals when MU-MIMO communication is performed, and to send the determined combinations of the users as schedule information, wherein an order of decoding the combinations of the users is determined on the basis of the receiving qualities of the terminals and accumulated redundant bit information about the terminals.
