摘要： A method for uplink channel estimation comprises providing (210) of a channel state model in a channel estimator. An up-link radio signal of a present time slot is obtained (220) in the channel estimator as well as a series of transmit power control commands (230) issued for controlling a transmit power of the uplink radio signal. A delay between the time a transmit power control command is issued and the time that the transmit power control command is applied is estimated (232) based on measurements of the particular received uplink radio signal. Channel states are adapted (234) based on a transmit power control command compatible with the estimated delay. After the adaptation, channel states of the present time slot are estimated (240) in the channel estimator, by tracking the demodulated uplink radio signal with the channel state model. A channel estimator performing such method is also described.

摘要： A method for power control stabilization in the uplink of a cellular CDMA communication system applying a fast inner loop power control comprises determining (210) of a radio frame based RoT value for a cell. A radio frame based SINR is determined (212) for individual UEs in the cell. The RoT value is compared (214) with a first threshold. Each frame based SINRs is compared (218) with a second threshold. The fast inner loop power control for a UE is broken (220) in dependence of the comparisons. The breaking comprises commanding (222) of a first number of consecutive power down commands to UEs having the frame based SINR above the second threshold for a RoT value above the first threshold and toggling (224) of power control commands for the subset of UEs during a second number of radio frames for a RoT value above the first threshold.

摘要： The embodiments herein relate to a method in a base station for transmitting an UpLink Transmit Power Control, UL TPC, command to a user equipment in a communications network. The base station obtains a measurement of a distortion of a signal received from the user equipment. The signal is associated with a power to be controlled. The base station determines that the signal is unreliable if the distortion measurement is above a threshold or determining that the signal is reliable if the distortion measurement is below the threshold. The base station transmits a first UL TPC command to the user equipment when the signal is determined to be unreliable or transmits a second TPC command to the user equipment when the signal is determined to be reliable.
