METHOD AND SYSTEM FOR OPERATING A MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT (MU-MIMO) WIRELESS COMMUNICATIONS SYSTEM

摘要

A technique for operating a wireless communications system that supports multi-user multiple-input multiple-output (MU-MIMO) communications between a base station and multiple mobile stations involves generating inter-cell interference information at the mobile stations and providing the inter-cell interference information to the base station. The base station uses the inter-cell interference information to calculate channel quality indicators (CQIs) and then makes scheduling decisions in response to the CQIs. Data is transmitted from the base station to the mobile stations according to the scheduling decisions.
