Cooperative transmission schemes can offer benefits in terms of diversity and multiplexing gain compared with conventional direct transmission by forming a virtual antenna array. I...
— Channel state information (CSI) is important for achieving large rates in MIMO channels. However, in timevarying MIMO channels, there is a tradeoff between the time/energy spen...

— We consider the problem of rate allocation in a fading Gaussian multiple-access channel with fixed transmission powers. The goal is to maximize a general concave utility funct...
The tremendous capacity gains promised by space division multiple access (SDMA) depend critically on the accuracy of the transmit channel state information. In the broadcast chann...
On a multiantenna broadcast channel, simultaneous transmission to multiple users by joint beamforming and scheduling is capable of achieving high throughput, which grows double log...
