| 20080214197 | Technique for Radio Resource Management - A radio resource management technique in a cellular telecommunication system is disclosed. The telecommunication system comprises at least one radio network controlling component and one or more base station components operable to implement an uplink scheduling scheme in relation to one or more user terminals. A method embodiment comprises the steps of receiving, by one of the base station components from the at least one radio network controlling component, at least one interference control parameter, of generating one or more scheduling grants taking into account the at least one interference control parameter, and of issuing the one or more scheduling grants to one or more user terminals. | 09-04-2008 |

| 20090270109 | ESTIMATING AND LIMITING INTER-CELL INTERFERENCE - A cellular radio communication system includes a first serving cell and a second non-serving cell. A mobile radio is currently served by a first base station in the first cell. An uplink radio transmission from the mobile radio will cause or causes inter-cell interference in the second non-serving cell. Accordingly, an estimate is made of the inter-cell interference in the second non-serving cell associated with the mobile radio's uplink transmission. If the estimated inter-cell interference in the second non-serving cell exceeds a predetermined threshold, then control is performed so that the inter-cell interference in the second non-serving cell is limited, e.g., by managing radio resources so that the estimated inter-cell interference in the second non-serving cell is or becomes less than the predetermined threshold. | 10-29-2009 |
| 20100029322 | Dynamic Adjustment of Power Offset for UE/BS Based on Error Event of NACK to ACK. - A radio network system employing a method with dynamic adjustment of the power offset that provides a “per-UE”-NACK to ACK power offset calculation method instead of using a fixed offset for all users in the cell is disclosed. Also for each UE, the power offset can adjusted dynamically. The adjustment is based on the error event of NACK to ACK. When an error event of NACK to ACK happens, the offset is increased, otherwise the offset is decreased. Hence, the offset can be controlled for each User Equipment for the duration of a call starting from some standard configured value is calculated and used rather than a fixed offset. | 02-04-2010 |
| 20100067389 | METHOD OF CONTROLLING POWER IN A WCDMA SYSTEM - A method and a device relating to a scheduling mechanism in a base station in a WCDMA system are disclosed. The mechanism enables the base station to rapidly adapt to users momentary traffic demands and to interference variations, a dynamical adjustable margin is proposed in this invention. The adjustment is based on the RoT measurement in a cell. To fully use the resource in a cell, the RoT can be targeted to be as closer to the RoT | 03-18-2010 |
| 20100087154 | Adjustments of IUB Load Measurements - A method may include determining whether a discrepancy exists between scheduling headroom computable by a first device and scheduling headroom computable by a second device, determining one or more load measurements that the second device bases its computation of the scheduling headroom if it is determined that the discrepancy exists, modifying the one or more load measurements, and calculating the scheduling headroom based on the modified one or more load measurements. | 04-08-2010 |
| 20100233962 | INTER-CELL INTERFERENCE CONTROL IN AN UPLINK MULTI-CARRIER RADIO COMMUNICATIONS SYSTEM - A multi-carrier cellular radio communication system includes a serving base station associate with a serving cell currently serving a mobile radio and a non-serving base station within range of the mobile radio and associated with a non-serving cell. The mobile radio can transmit to the serving base station at the same time over multiple radio frequency carriers. An estimate is made of inter-cell interference in the non-serving cell caused by uplink transmission by the mobile radio over one or more of the multiple radio frequency carriers over which the mobile radio is currently simultaneously transmitting. If the estimated inter-cell interference in the non-serving cell exceeds a predetermined threshold, then the inter-cell interference in the non-serving cell is reduced or limited by managing radio resources so that the estimated inter-cell interference in the non-serving cell is or becomes less than the predetermined threshold. | 09-16-2010 |
| 20100323746 | Method of Transmitting TPC Commands - In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be. | 12-23-2010 |
