This paper proposes an adaptive resource allocation scheme to cope with heterogeneous traffic for multiuser multiple-input multiple-output orthogonal frequency division multiple access (MU-MIMO-OFDMA). The feature of the proposed approach is to maximize the frame efficiency by simultaneously allocating frequency and space resources under different user's packet size and channel condition. However,...
We consider the proportional fair rate allocation in an 802.11 WLAN that supports multi-user MIMO (MU-MIMO) transmission by one or more stations. We characterise, for the first time, the proportional fair allocation of MU-MIMO spatial streams and station transmission opportunities. While a number of features carry over from the case without MU-MIMO, in general neither flows nor stations need to be...
Providing high data rates to wireless users has long been a goal that has driven the development of new technologies and standards in the past decade. Now, with the opening up of the spectrum at 60 GHz, it has become possible to design WLANs that can meet the goal of Gbps/user connectivity. This paper examines several unique design challenges brought about because of the physical characteristics of...
