INFERENCE ALIGNMENT (IA) METHOD FOR UPLINK IN WIRELESS LOCAL AREA NETWORK (WLAN) SYSTEM, ACCESS POINT (AP) AND USER TERMINAL FOR PERFORMING THE SAME

摘要

An interference alignment (AI) method for an uplink in a wireless local area network (WLAN) system, an access point (AP) and a user terminal for performing the same, and the AP that may select an interference space, broadcast information on the selected interference space, select a user terminal to be assigned a data transmission opportunity based on leakage of interference (LIF) information received from at least one user terminal, receive data from the user terminal, and decode the data using a minimum square error (MMSE) based receiving filter.

1. An interference alignment (IA) method performed by an access point (AP), the method comprising:
selecting an interference space; broadcasting information on the selected interference space; selecting a user terminal to be assigned a data transmission opportunity based on leakage of interference (LIF) information received from at least one user terminal; receiving data from the selected user terminal; and decoding the data using a minimum mean square error (MMSE) based receiving filter.
