A quantized multi-rank beamforming scheme for multiple-antenna systems such as a
multiple-input-multiple-output (MIMO) wireless downlink. User equipment (UE) estimates …

Throughput maximization of an adaptive transmission system with a finite number of
transmission power levels and code rates for communication over slow fading channels is …

We consider a slow-fading narrowband multiple-input multiple-output (MIMO) multiple-
access channel (MAC) in which multiple users, each equipped with multiple transmit …

This paper presents a review of techniques proposed in the literature that target the best use
of resources available in a wireless communication system. These are referred to as …

A base station used in a wireless communications system with multiple transmission ranks is
disclosed. The base station comprises a memory to store a codebook for a transmission …

OSC (Orthogonal Sub Channel) is an enhancement for the GSM voice traffic. It provides up
to double capacity in the GSM radio interface with the same hardware compared to the …

It is well-known that MIMO links in slow fading channels can benefit significantly through rate
and power adaptations when there is knowledge of channel state information at the …

A base station used in a wireless communications system with multiple transmission ranks is
disclosed. The base station comprises a memory to store a codebook for a transmission …

A novel approach, utilizing the virtual multiple-access like capacity region with symmetry
condition on rates, is used to develop the design criterion of linear precoding (inner code) for …

We consider a slow-fading narrowband multiple access channel (MAC) in which multiple
