Abstract
Uplink multiple-input multiple-output (MIMO)
transmission scheme is developed for time division duplex (TDD)
systems in a multicell environment. We propose a precoding
scheme that maximizes the total achievable rate and works in
the decentralized manner with only locally available channel
state information (CSI) at each transmitter. We first establish
and solve a decentralized optimization problem for the case of
multiple-input single-output (MISO) channels, introducing a new
precoding design metric called signal to generated interference
plus noise ratio (SGINR). By extending the result to general
MIMO channels, we propose an SGINR-based precoding scheme
where the number of transmit streams is selected adaptively to
the surrounding environments. Simulation results confirm that
the proposed precoding scheme offers significant throughput
enhancement in multicell environments.
