20100111209 | DTF Spread OFTM - The invention applies DFT-spread-OFDM which is proposed for the 3GPP LTE uplink. The core of the invention is that we use a cyclic frequency shift operation over part of the bandwidth spanned by the IFFT.

20100113057 | USING AN UPLINK GRANT AS TRIGGER OF FIRST OR SECOND TYPE OF CQI REPORT - Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information. | 05-06-2010 |

20110053602 | REPEATER GAIN CONTROL METHOD AND APPARATUS - This document proposes soft activation and inactivation of (network) repeaters that are, for example, activated on an as-needed basis.

Likewise, with soft inactivation, repeater gain ramps downward at a controlled rate. Soft activation/inactivation results in more gradual changes in the interference contribution of the repeater, thereby improving the performance of interference-compensating radio receivers operating in proximity to the repeater. | 03-03-2011 |
