| 20080291865 | Multiple access spread spectrum switching methodology - A low-cost, low-power, low-complexity, small, high-reliability, robust, seamless satellite communication network is described. The network performs encoding of a user signal at the customer premises to enable routing of the user signal to an appropriate destination beam at the satellite requiring low power user signal processing. Routing information is embedded at the periphery of the network CPE's rather than at the satellite. Embedding the routing information in this way greatly reduces on-board switching complexity and increases signal to interference ratio for the user. | 11-27-2008 |
| 20090022089 | ARCHITECTURE TO SUPPORT NETWORK-WIDE MULTIPLE-IN-MULTIPLE-OUT WIRELESS COMMUNICATION - The present invention provides a method of coordinating transmission by and reception by a plurality of antennas associated with a plurality of radio heads.

| 20090029714 | METHOD OF ALLOCATING BANDWIDTH FOR TRANSMISSION OF CHANNEL QUALITY INFORMATION - The present invention provides a method of allocating bandwidth for transmission of channel quality information. The method includes reducing a bandwidth allocated to transmission of channel quality information over an air interface in a first direction in response to determining that traffic over the air interface in the first direction has increased. | 01-29-2009 |
| 20090312042 | INTER-SECTOR MACRODIVERSITY INTERFERENCE CANCELLATION AND SCHEDULING - The present invention provides a method for interference cancellation in a wireless communication system. One embodiment of a method includes accessing information indicative of one or more first signals transmitted by one or more first mobile units from one or more first sectors. The method also includes accessing information indicative of one or more second signals transmitted by one or more second mobile units from one or more second sectors different than the first sectors. The method further includes canceling interference caused in the second signal(s) by the first signal(s) using the accessed information indicative of the first signal(s) and the second signal(s). The method also includes jointly scheduling and allocating resources to one or more mobile stations in one or more sectors of one or more base stations. | 12-17-2009 |
| 20100008332 | Method for half-and full-duplex subscriber station operation in frequency division duplex systems - The present invention provides a novel framing structure that can be used to smoothly evolve a Time Division Duplex (TDD) wireless communications technology to a Frequency Division Duplex wireless communications technology.

| 20100284345 | System and method for cell-edge performance management in wireless systems using distributed scheduling - A method is provided for scheduling transmission resources to a mobile station served by a plurality of base stations. According to the method of the invention, feedback information respecting data received by the mobile station from each of at least two of the plurality of base stations is received by the each of the plurality of base stations. An inference is then drawn at a second of the plurality of base stations of throughput parameters respecting a transmission channel between a first of the plurality of base stations and the mobile station. Transmission resources for the mobile station are then scheduled by the second base station as a function of the inferred throughput parameters. | 11-11-2010 |

According to the method of the invention, a centralized scheduler is provided at a network node operative to serve each of the plurality of base stations and the centralized scheduler acts to prioritize scheduling of transmission resources to the mobile station as a function of feedback information respecting data received by the mobile station from each of at least two of the plurality of base stations. | 11-11-2010 |
| 20100291935 | Multi-stream wireless relay - A multi-stream wireless relay is arranged to maintain independent data streams with multiple base stations and thereby provide a relay from those multiple base stations to mobile units having respective communication relationships with those multiple base stations. In an alternative approach, the data streams from the multiple base stations are superposed on each other, wherein harmful inter-cell interference is converted into useful information bearing signals, thereby enabling the scheduling of transmission resources from the multiple base stations for a single mobile unit via the relay. | 11-18-2010 |
