    • 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.

    • A method in conjunction with positioning of a mobile terminal in a cellular telecommunication system is disclosed. According to the method, an end user's requested positioning accuracy for the positioning of the mobile terminal is determined (510). Also, an estimated confidence value for the positioning of the mobile terminal is determined (520), and so is a required confidence value for the end user (530). Then, a pre-scale value is produced (540) based on at least the estimated confidence value and the required confidence value. The pre-scale value is applied (550) to the requested positioning accuracy to obtain a pre-scaled requested positioning accuracy. Then, the pre-scaled requested positioning accuracy is sent (560) in the cellular telecommunication system towards the mobile terminal.

    • A scaling apparatus and method scales uncertainty criteria (horizontal and vertical accuracy requirements) originally received from an end user before the uncertainty criteria is sent on to a wireless terminal (30) as requirements on the accuracy of location positioning performed by/for the wireless terminal. In an example embodiment the amount/degree of scaling is selected according to a configured best estimate of the confidence and uncertainty relation, and such best estimate can be based on the majority of the terminals of the network. For a WCDMA radio access network (RAN) case the scaling can be performed in a radio network controller (RNC). For a Long Term Evolution (LTE) radio access network (RAN) case the scaling can be performed in the evolved Serving Mobile Location Center (eSMLC) node (26). In another case the scaling can alternatively be performed in the wireless terminal itself.
