Claim:
1. A method performed by a first device for estimating a radio channel between the first device and a second device in a telecommunications system comprising receiving, by one or more processors, common pilot signals and demodulation signals over the radio channel in transmissions from the second device; estimating, by the one or more processors, the radio channel based on the common pilot signals and the demodulation pilot signals, wherein the estimation comprises: performing a first estimation of the radio channel based on the common pilot signals; performing a second estimation of the radio channel based on the demodulation pilot signals; estimating the radio channel based on the first and second estimation of the radio channel, wherein the weight factors of the weighted sum of the first and second radio channel estimations are based on the power levels of the common pilot signal and the demodulation pilot signal, respectively; and determining, by the one or more processors, the radio channel based on the common pilot signals and the demodulation pilot signals.
