We consider a multi-link and multi-input-multi-output (MIMO) interference system in which each link wishes to minimize its own power by choosing its own signal vector subject to an information theoretic quality-of-service (QoS) requirement. Our setup leads to a multi-link game, referred to as a ldquopower gamerdquo, in which the feasible strategy set of an individual link depends on the strategies...
This paper considers a multi-user MIMO broadcast wireless channel where a MAC layer scheduler is used to improve system efficiency and provide quality of service improvements (fairness) to users. In particular, an alpha-rule scheduler is considered that uses rate estimates from users to make user selection decisions. The main challenge faced by the scheduler is that users need to estimate the interference...
