20080310343 | Methods of jointly assigning resources in a multi-carrier, multi-hop wireless communication system - Methods for jointly determining tones, power, scheduling and routing of links in a multi-carrier, multi-hop network to achieve certain desired throughput objectives between source and destination nodes. The methods effectively enhance or optimize throughput received by each destination router under node traffic constraints such as power, scheduling and flow constraints that apply to each link between each of a plurality of nodes within the mesh network. | 12-18-2008 |
20100118926 | METHODS AND DEVICES FOR SELECTING SETS OF AVAILABLE SUB-CHANNELS - Information is transmitted over selected, Orthogonal Frequency Division Multiplexed (OFDM) sub-channels to avoid frequencies with unacceptable congestion, noise or interference levels. Using frequency hopping, selected non-contiguous OFDM sub-channels used for transmission may vary with time. Once a group of OFDM sub-channels is selected, a power level and modulation technique may also be selected based on channel quality. | 05-13-2010 |
20100215108 | Ranking and Grouping of Transmissions in Communication System - Improved ranking and grouping techniques are disclosed for communication systems such as a multiple input multiple output system.

20120071153 | Receive Signal Processing In Wireless Networks - Among the various methods proposed to address interference problems in wireless networks, two promising ones are: Network Multi-Input-Multi-Output (often referred to as Network MIMO) decoding (which employs joint MIMO receiver processing of signals received at multiple antennas); and Multi-Cell Successive Interference Cancellation (MC-SIC). These methods have complementary strengths and limitations when implemented in a practical setting. The approach described herein attempts to combine the strengths of these two methods while working within the constraints imposed by practical implementations to provide a viable hybrid solution. | 03-22-2012 |
