| 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. Furthermore, the cyclic frequency shift enables efficient inter-cell interference coordination in case neighbouring cells hop with the same pattern and different initial offsets. Equivalent operation may be performed in the time domain. | 05-06-2010 |
| 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 |
| 20110014911 | METHOD AND ARRANGEMENT FOR REPEATER/RELAY CONTROL - In a method in a controllable repeater in a telecommunication system, said system comprising a radio base station, at least said controllable repeater and a plurality of user terminals, receiving a list of associated user terminal identities for said repeater, and searching for and decoding downlink channel control messages based on said provided list. | 01-20-2011 |
| 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. With soft activation, repeater gain ramps upward at a controlled rate, thereby avoiding rapid changes in interference caused by the repeater. 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 |

Load statistics on RACH and PUSCH are collected used for determining a number of RACH opportunities required per time unit. Then a new PRACH configuration parameter having said required number of RACH opportunities per time unit is selected which is replacing the old PRACH configuration parameter. | 04-28-2011 |
