We study auction mechanisms for sharing spectrum among a group of users, subject to a
constraint on the interference temperature at a measurement point. The users access the …

We consider a user communicating over a fading channel with perfect channel state
information. Data are assumed to arrive from some higher layer application and are stored in a …

Multiuser diversity refers to a type of diversity present across different users in a fading
environment. This diversity can be exploited by scheduling transmissions so that users transmit …

We consider a distributed power control scheme for wireless ad hoc networks, in which each
user announces a price that reflects compensation paid by other users for their interference. …

A fundamental problem in networking is the allocation of limited resources among the users
of the network. In a traditional layered network architecture, the resource to be allocated at …

We consider scheduling and resource allocation for the downlink of a cellular OFDM system,
with various practical considerations including integer tone allocations, different sub-…

Orthogonal frequency division multiplexing (OFDM) with dynamic scheduling and resource
allocation is a key component of most emerging broadband wireless access networks such …

To achieve the full multiplexing gain of MIMO interference networks at high SNRs, the
interference from different transmitters must be aligned in lower-dimensional subspaces at the …

We develop medium access control protocols to enable users in a wireless network to
opportunistically transmit when they have favorable channel conditions, without requiring a …

We consider a spectrum sharing problem in which each wireless transmitter can select a
single channel from a set of available channels, along with the transmission power. An …
