Abstract: A method for uplink channel estimation comprises providing of a channel state model in a channel estimator. An uplink radio signal of a present time slot is obtained in the channel estimator as well as a series of transmit power control commands 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 based on measurements of the particular received uplink radio signal. Channel states are adapted based on a transmit power control command compatible with the estimated delay. After the adaptation, channel states of the present time slot are estimated 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.

Abstract: Apparatus and method for reducing an air interface load in a communication network. A base station is provided with a receiver adapted to receive signals from a terminal via a Dedicated Physical Control Channel (DPCCH) and a second control channel. A measuring unit measures a signal to interference ratio (SIR) of the DPCCH. An effective SIR determining unit determines an effective SIR on the basis of the measured SIR of the DPCCH and an estimate of the SIR of the second control channel. A comparison unit compares the effective SIR with a target SIR, and a power determination unit determines a power control command for controlling power usage for the DPCCH on the basis of the comparison. A transmitter sends a message to the terminal, the message including the power control command. The invention allows the DPCCH power (or DPCCH SIR) operating point to be maintained at a low level.

Abstract: 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 Long Term Evolution (LTE) radio access network (RAN) case the scaling can be performed in the evolved Serving Mobile Location Center (eSMLC) node. In another case the scaling can alternatively be performed in the wireless terminal itself.
