| 20080219235 | System and Method for Frequency Division Multiple Access Communications - A method and system for wireless frequency division multiple access communications in the uplink and/or downlink directions, having an improved pilot insertion scheme for single carrier based communications is provided. A first time duration for transmission of a data payload block ( | 09-11-2008 |
| 20090274112 | Initial Access Channel for Scalable Wireless Mobile Communication Networks - Physical layer structures and access schemes for use in such networks are described and in particular initial access channel (IACH) structures are proposed. A spectrum efficient downlink (DL) IACH design supports different types of User Equipment (UE) capabilities and different system bandwidths. An IACH includes the synchronization channel (SCH) and broadcast-control channel (BCH). A non-uniform SCH for all system bandwidths is provided, as well as scalable bandwidth BCH depending on system bandwidth. An initial access procedure is provided, as well as an access procedure. | 11-05-2009 |

| 20090245197 | Methods and systems to mitigate inter-cell interference - The present invention provides methods and devices for mitigating inter-cell interference in communication environments having a plurality of cells. In some embodiments, a time-frequency transmission resource that includes multiple sub-carriers over multiple OFDM symbol intervals is partitioned into a first zone and a second zone. In the first zone, transmissions are transmitted on at least one frequency sub-band which is common to all of the plurality of cells. In the second zone, transmissions are transmitted on at least one frequency sub-band which is used by less than all of the plurality of cells, so as to mitigate inter-cell interference. In some embodiments, in the first zone transmissions are transmitted using a transmission power which is common to all of the plurality of cells and in the second zone transmissions are transmitted using a transmission power which is used by less than all of the plurality of cells so as to mitigate inter-cell interference. | 10-01-2009 |
