20120188881 | Adaptive Transmission Systems and Methods - Abstract Spatial multiplexing and transmit diversity can improve the capacity of a wireless communication system. The system and method adapts communication schemes for communication systems with multiple antennas utilizing at least two transmission modes. The at least two transmission modes can, but are not necessarily, used for uplink communications. The two transmission modes may be chosen from the group consisting of a single antenna mode, a diversity mode a spatial multiplexed mode and a mixed diversity and spatial multiplexed mode. The at least two transmission modes may involve adaptation among multiple transmitters. At least one receiver may indicate a transmission mode to be used by a transmitter for a subsequent transmission. A transmitter may determine a transmission mode to be used for a subsequent transmission. The transmission mode can be based on channel sounding. | 07-26-2012 |
20120188946 | 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. A first time duration for transmission of a data payload block is established, and the transmission is processed using a first frequency domain or a time domain. A second time duration for transmission of at least one pilot block is established, and the transmission is processed using a second frequency domain or the time domain, the second time duration is not greater than the first time duration. | 07-26-2012 |

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 |
20130021913 | FEEDBACK INFORMATION IN A MULTI-CARRIER WIRELESS TELECOMMUNICATIONS NETWORK - Apparatus and method for encoding and transmitting feedback information from a first network node to a second network node in a multi-carrier wireless telecommunications network. The first network node is operable to receive signals from the second network node on two or more reception carriers and transmit data to the second network node on one or more transmission carriers. Each reception carrier being transmitted within an associated a radio band. The method comprises the steps of: (i) monitoring for a signal on at least two of the reception carriers; (ii) generating feedback information for at least two of the reception carriers based upon received signals; (iii) grouping the feedback information for reception carriers being transmitted within the same radio band; and encoding said grouped feedback information for two or more reception carriers being transmitted within the same radio band; and iv) transmitting the encoded feedback information to the second network node on one or more transmission carriers. | 01-24-2013 |
