Abstract: To increase positioning accuracy, channel characteristics are determined taking into account receive filter response and transmit filter response. For example, upon receiving assistance data for positioning an apparatus, a transmit sequence is generated using the assistance data; and a combination of the transmit sequence is generated by combining the transmit sequence. Further, a receive filter response is determined, a transmit filter response is obtained, and a combined filter response is generated using the receive filter response and the transmit filter response. Reference signals received over a channel are measured by sampling them into a plurality of time-domain samples, and the channel is estimated from the plurality of time-domain samples using the combined filter response and the combination of the transmit sequence. Then, per channel characteristics, a value of the channel characteristics based on the channel estimated is determined.

Abstract: Disclosed herein are systems, methods and/or computer programs for determining time and/or angle-based measurements for use in position determination. The apparatus may comprise means for receiving, at a plurality of antennae, a reference signal associated with positioning and determining cross-correlation values comprising a cross correlation between the reference signal received at each antenna and a known reference signal associated with positioning. There may also be provided means for estimating a channel response for a reference antenna of the plurality of antennae using the cross correlation values, the known reference signal and an antenna correlation comprising a known relationship between a channel response of each antenna of the plurality of antennae and the channel response of the reference antenna, and determining a time of arrival and/or an angle of arrival of the received reference signal based on the estimated channel response for the reference antenna.
