摘要： An uplink signal-to-interference ratio for each of multiple mobile radio terminal connections supported in a cell in a cellular communications system is estimated. A signal-to-interference ratio error is determined for selected ones of the estimated uplink signal-to-interference ratios. One or more signal-to-interference ratio errors are identified that exceed a signal-to-interference ratio error threshold. An instability indicator associated with the cell is determined based on the one or more identified signal-to-interference ratio errors. A load control decision and/or a decision for scheduling one or more uplink mobile radio transmissions in the cell may then be made based on the instability indicator, e.g., to prevent a transmission power rush in the uplink in the cell and/or to efficiently use available resources for uplink transmissions.

摘要： The present invention relates to methods and arrangements in a wireless communication system, and in particular to uplink outer loop power control. A Node B identifies if a UE from which the Node B receives data is in a predetermined set of power challenged situations. The Node B transmits to the RNC an indication to hold the SIR target of the UE if the UE has been identified to be in a power challenged situation. As a consequence, the uplink outer loop power control (OLPC) procedure in the RNC will not change the SIR target of the UE. This implies that the output power level of the UE remains unchanged as long as the UE remains in the power challenged situation. Thus, user and network performance are improved in the wireless communication system.

摘要： Control of uplink transmit power for a first mobile station operating with scheduled uplink data transmissions. A change in uplink scheduled status for the first mobile station is detected (301). Filtering of uplink interference measurements for the first mobile station is adapted (302) to account for the detected change in uplink scheduled status for the first mobile station. Alternatively a change in uplink scheduled status for a second mobile station is detected and a current filtering state for filtering of uplink interference measurements for the first mobile station is adjusted by applying an estimated expected change in interference associated with the detected change. A signal quality for uplink transmissions from the first mobile station is determined (303) based on measurements of received signal strength from the mobile station and the filtered uplink interference measurements. An uplink transmit power command is generated (304) for the first mobile station based on a comparison of the estimated signal quality to a signal quality target.
