Multi-Rank Beamforming Precoding Apparatus And Method

US Patent:
7949318, May 24, 2011
Filed:
Feb 5, 2008
Appl. No.:
12/026120
Inventors:
Narayan Prasad - North Brunswick NJ, US
Mohammad Ali Khojastepour - Plainsboro NJ, US
Mohammad Madihian - Plainsboro NJ, US
Xiaodong Wang - New York NY, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
H04B 1/04
US Classification:
455129, 455102, 375267
Abstract:
A multi-rank beamforming (MRBF) scheme in which the downlink channel is estimated and an optimal precoding matrix to be used by the MRBF transmitter is determined accordingly. The optimal precoding matrix is selected from a codebook of matrices having a recursive structure which allows for efficient computation of the optimal precoding matrix and corresponding Signal to Interference and Noise Ratio (SINR). The codebook also enjoys a small storage footprint. Due to the computational efficiency and modest memory requirements, the optimal precoding determination can be made at user equipment (UE) and communicated to a transmitting base station over a limited uplink channel for implementation over the downlink channel.

Coordinated Linear Beamforming In Downlink Multi-Cell Wireless Networks

US Patent:
8218422, Jul 10, 2012
Filed:
Jun 3, 2009
Appl. No.:
12/477255
Inventors:
Luca Venturino - Cassino, IT
Xiaodong Wang - New York NY, US
Narayan Prasad - Monmouth Junction NJ, US
Assignee:
NEC Laboratories America, Inc. - Princeton NJ
International Classification:
H04J 11/00
US Classification:
370208, 370310, 370328, 370329, 370330
Abstract:
System and methods are disclosed for optimizing wireless communication for a plurality of mobile wireless devices. The system uses beamforming vectors or precoders having a structure optimal with respect to the weighted sum rate in a multi-cell orthogonal frequency division multiple access (OFDMA) downlink. A plurality of base stations communicate with the mobile devices and all base stations perform a distributed non-convex optimization exploiting the determined structure.
