| 20120094689 | METHOD OF AND SYSTEM FOR SIGNAL ANALYSIS IN A WIRELESS COMMUNICATIONS SYSTEM - A method of and system for calibrating a repeater in a wireless communications system are provided. The one or more calibration parameters for the repeater are derived from (a) time measurements derived from one or more signals relayed by the repeater and received at a plurality of different measurement positions, and (b) the positions of the measurement locations. In one application, the one or more parameters are used in determining the positions of subscriber stations in the wireless communications system. | 04-19-2012 |
| 20110018780 | Antenna Array For Multiple In Multiple Out (MIMO) Communication Systems - The present disclosure provides techniques for configuring multiple element antenna arrays for use in multiple input multiple output (MIMO) communications. The antenna arrays include a ground plane and antenna elements. The ground plane forms an electrically conductive surface having a ground potential. The antenna elements, located near the ground plane, transmit and receive a wireless communication signals over a predetermined wireless channel. | 01-27-2011 |
| 20100190512 | METHOD FOR AMBIGUITY RESOLUTION IN LOCATION DETERMINATION - A method using various heuristics techniques for resolving ambiguity in location determination in environments with or without noise. A final location determination solution may be determined from a set of ambiguous location determination solutions by using clock temporal bias value, by using consistency information of ranging signal order such as the time of arrival and/or the received power level of the ranging signals, by using the distances to the sources, and/or by using other discriminator functions to select the final location determination solution from a plurality of ambiguous location determination solutions. The main advantage of the heuristic approaches is that redundant measurements are not required for location determination solution disambiguation. | 07-29-2010 |
| 20100027471 | SYSTEM AND METHOD FOR DISTRIBUTED MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) IN A WIRELESS COMMUNICATION SYSTEM - Systems and methodologies are described herein that facilitate distributed multiple-input multiple-output (MIMO) or cooperative multipoint (CoMP) communication in a wireless communication system. As described herein, multiple cells, such as a serving cell and an auxiliary cell, can cooperate to conduct communication with one or more associated terminals. In one example described herein, an associated core network can exchange data and/or control signaling with a single cell communicating with a given terminal, which can then tunnel respective data and/or control signaling to other cell(s). By doing so, CoMP communication can be made transparent to the core network and can be achieved without requiring changes to the network. As further described herein, a terminal can exchange Physical Downlink Control Channel (PDCCH) assignments and/or other information exclusively with the serving cell in addition to or in place of other information exchanged with a serving cell and/or an auxiliary cell. | 02-04-2010 |
| 20090232079 | FRAME STRUCTURES FOR WIRELESS COMMUNICATION SYSTEMS - Superframe preamble structures for wireless communication systems are provided. The preamble can include system determination information, which can improve acquisition performance. The superframe structures can allow efficient determination of flexible parameters that determine preamble structure. The superframe structures can also facilitate quick paging capacity to scale with bandwidth. | 09-17-2009 |
| 20090116438 | DIVISION OF THE SCHEDULING ALGORITHM INTO BACKGROUND AND FOREGROUND ALGORITHMS - Systems and methodologies are described that facilitate dividing scheduling algorithms into background and foreground aspects capable of simultaneously servicing a multiplicity of disparate flows in wideband communications networks. The systems provided herein arbitrarily select prospective time horizons, generate optimal bandwidth allocation targets based on a plurality of flows observed by the system, and utilizes the optimal bandwidth targets to assign flows to users over the entirety of the prospective time horizon. | 05-07-2009 |
| 20090069041 | SCHEDULING INFORMATION TRANSFER - A base station can transmit scheduling unit to mobile device that can enhance mobile device functionality. To transmit the scheduling unit efficiently, the information can be broken down into manageable units. The broken down units can be organized into groupings that enable the units to be sent as a function of available resources. Transmission can continue until a mobile device receives the scheduling unit, where re-organization can occur for a subsequent transmission. | 03-12-2009 |
