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 network node comprising a rake receiver (300) for enabling SNR error compensation. The rake receiver (300) obtains (202, 203, 602) a SNR gain error of a signal associated with an antenna (301). The rake receiver (300) multiplies (204, 205, 603) a first sub signal with a first weight parameter, and the first sub signal with the SNR gain error, thereby providing a first rake finger value. The rake receiver (300) multiplies (204, 205, 604) a second sub signal with a second weight parameter, and the second sub signal with the SNR gain error, thereby providing a second rake finger value. For the first antenna (301), the rake receiver (300) combines (206, 207, 605) the first rake value with the second rake value. Further, it decodes (208, 209, 607) the combined first rake finger value and the second rake finger value.

摘要： A method for uplink channel estimation comprises providing (210) of a channel state model in a channel estimator. An uplink 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： The embodiments herein relates to a method in a base station (101) for transmitting an UpLink Transmit Power Control, UL TPC, command to a user equipment (103) in a communications network (100). The base station (101) obtains a measurement of a distortion of a signal received from the user equipment (103). The signal is associated with a power to be controlled. The base station (101) determines that the signal is unreliable if the distortion measurement is above a threshold or determining (308) that the signal is reliable if the distortion measurement is below the threshold. The base station (101) transmits a first UL TPC command to the user equipment (103) when the signal is determined to be unreliable or transmits a second TPC command to the user equipment (103) when the signal is determined to be reliable.
