发明名称 Power control method and mobile communication terminal
摘要 A power control method performed by a mobile communication terminal comprises determining a received signal code power of common pilot channel signals received from a base station on a common pilot channel in at least one time interval. A block error rate determination is performed to determine a block error rate for transmissions received from the base station. A downlink outer loop power control is performed in dependence on the determined received signal code power of the common pilot channel signals until the block error rate determination fulfills a convergence criterion.

主权项 1. A power control method performed by a mobile communication terminal, the power control method comprising: determining a received signal code power of common pilot channel signals received from an individual base station on a common pilot channel in at least one time interval; performing a block error rate determination to determine a block error rate for transmissions received from the individual base station; and performing a downlink outer loop power control, wherein, in response to a connection setup, the downlink outer loop power control is performed in dependence on the determined received signal code power of the common pilot channel signals until the block error rate determination fulfills a convergence criterion, wherein determining the received signal code power comprises: determining a first received signal code power of the common pilot channel signals in a first time interval at completion of the connection setup, anddetermining a second received signal code power of the common pilot channel signals in a second time interval which starts later than the first time interval; wherein the downlink outer loop power control is performed in dependence on a comparison between the second received signal code power and the first received signal code power until the block error rate determination fulfills the convergence criterion.
