20100081469 | Multi Mode Outer Loop Power Control in a Wireless Network - A method and arrangement is provided for adjusting the transmission power of radio signals sent over a radio link from a second node to be received by a first node reducing the transmission power consumption and/or optimizing the radio system capacity. The first node maintains a quality target of the link by generating a SIR target value by means of running an outer loop power control, which SIR target value is used for generating a power adjustment command to be sent to the second node for adjusting the transmission power such that a power level adequate for providing the quality target of the link is achieved. The method comprises the step of detecting an abrupt change in the conditions of the radio signals received from the second node, generating a temporary SIR target value, and replacing the SIR target value generated by the outer loop power control with the temporary SIR target value when generating the power adjustment command to be sent to the second node for adjusting the transmission power. | 04-01-2010 |
20100135169 | Channel Quality Reporting Method and Arrangement in a Telecommunication System - When a high SIR can be achieved for downlink data transmission, for example in a MIMO system, or when higher order modulation, such as 64 QAM, can be used, it is desired to measure the instantaneous downlink channel quality indicator (CQI), and report the measured CQI to the network using the same number of bits as when a lower SIR can be achieved. In order to do this, a true CQI is derived based upon at least one network controlled parameter and a measured channel quality parameter; and the true CQI value is scaled to a new CQI value such that the new CQI will fall within a specified range of CQI values; so that the new CQI achieved by scaling the derived CQI value can be reported with every CQI value over the entire reporting range requiring the same number of bits. | 06-03-2010 |

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 |
