20080233966 | Resource allocation apparatus and method in an orthogonal frequency division multiple access communication system - A novel and useful method and system for resource allocation in OFDM communication systems. The mechanism reduces inter-cell interference by randomizing the inter-cell interference experienced in each cell. The mechanism effectively spreads the resource allocation in each cell in a random manner resulting in statistical-like inter-cell interference behavior. In many cases, use of the mechanism is sufficient to obviate the need for frequency planning between cells. A formula or hardware permutation machine is used to generate a random list of indices. The indices are then used to assign user data to the system resources. One or more parameters defining the random index generator at the transmitter are forwarded to the receiver to enable the local generation of an exact copy of the list of indices generated at the transmitter, thus enabling the DL and UL at the receiver while minimizing the required control channel signaling. | 09-25-2008 |
20090219849 | APPARATUS FOR AND METHOD OF MULTICAST AND BROADCAST SERVICE (MBS) MACRO-DIVERSITY BASED INFORMATION PROCESSING - A novel and useful apparatus for and method of multicast and broadcast service (MBS) macro-diversity based information processing for use in MBS enabled wireless communication systems. MBS allocations and transmissions from base stations are not coordinated and independent of each other. The characteristics of the MBS signal, such as waveform, modulation, timing and frequency domain, used for transmissions in one or more MBS zones by a base station are uncoordinated and unsynchronized with respect to transmissions in other base stations or MBS zones. They all, however, contain the same information content and relate to the same CID (MCID and/or SA). The MS, using multiple detection techniques, uses time and frequency diversity reception techniques to combine MBS transmissions received from multiple base stations. Base stations and/or the network inform mobile stations of whether or not uncoordinated MBS data transmission is supported on the network via a TLV transmitted during the MBS connection setup process. If supported, mobile stations can receive multiple MBS data signals, combining them to generate a single MBS data output stream. | 09-03-2009 |
20100234071 | VEHICLE INTEGRATED COMMUNICATIONS SYSTEM - A novel and useful vehicle integrated communications system that provides a solution to the poor performance experienced at the cell edge in a cellular communications system due to weak signal strength and high interference levels. A core cellular communications platform embedded (integrated) into the vehicle platform utilizes multiple antennas integrated into the body of the vehicle which are coupled to a multi-antenna transceiver; receives electrical power from the vehicle power source eliminating the limitations of hand held device batteries; processes multiple MIMO RF signals taking advantage of antenna diversity, beamforming and spatial multiplexing; executes advanced interference mitigation algorithms; implements adaptive modulation and coding algorithms; and utilizes dynamic channel modeling and estimation to significantly improve performance. The core cellular link functions as a platform for any number of vehicle based applications including a smart vehicle repeater, mobile femtocell, inverted femtocell and vehicle infotainment system. | 09-16-2010 |

20140194149 | SINGLE TRANSCEIVER FOR USE WITH MULTIPLE CELLULAR NETWORKS - A system and method for wirelessly communicating over two wireless networks having different communication protocols using a single transceiver of a vehicle telematics unit. The method includes monitoring a first network for an incoming page using a transceiver and a first network access device (NAD); the transceiver and the first NAD may be components of a cellular device, such as a vehicle telematics unit. The method includes monitoring a second network for another incoming page using the same transceiver and a second NAD. The second NAD also may be a component of the cellular device. When a page is received over the second network, a call may be connected using the second NAD, and the first network may be periodically monitored for an incoming page without disconnecting the call of the second network. | 07-10-2014 |
20140213216 | METHODS AND SYSTEMS FOR BASE STATION DETECTION - Methods and systems for unauthorized base station detection are disclosed herein. In an example of the method, an in-vehicle controller of a vehicle or an application of a mobile communications device scans a cellular radio environment to identify an available base station. By a signal detection unit in operative communication with the in-vehicle controller or the application, a strength of a signal of the available base station is detected. The in-vehicle controller or the application recognizes that the signal strength is out of the expected signal strength range, and determines that the available base station is the unauthorized base station. While in connection with the unauthorized base station, the in-vehicle controller or the application determines a location of the unauthorized base station. Other examples of the method are also disclosed herein. | 07-31-2014 |
20140274048 | INTEGRATING IN-VEHICLE ACCESS-POINT WITH CELLULAR OFFLOADING SYSTEM - A method and system for selectively providing cellular offload services to mobile user data devices via vehicle-based access points. Subscribers and affiliates of vehicle-related online services register their user data devices for authorized connections. Vehicle metrics are used to determine the state of a vehicle (being driven or parked), and the metrics of the user device can be compared with the vehicle metrics to determine if the user device is inside the vehicle. Limiting access to authorized user devices reduces load on the vehicular access points and allows preventing the vehicular access points from being erroneously included on access point maps and thereby infecting the maps. | 09-18-2014 |
20140274069 | CELLULAR OFFLOADING SYSTEM FOR VEHICLES APPROACHING ACCESS POINTS - Systems and methods for compiling lists of prospective access points for offloading cellular data traffic for a vehicle, and for selecting an access point to establish a non-cellular wireless Internet connection. Vehicular data mobile access involves properties and characteristics different from those of portable user data devices, and thus exhibit different criteria for cellular data offloading. Embodiments of the invention provide vehicle metrics to be used in conjunction with data requirement metrics in compiling the access lists and making the optimum selections based on the vehicle's predicted route. A predictive look-ahead is also provided, for use when predictive routing information is not available or is unreliable. | 09-18-2014 |
