Reference signal measurement |
摘要 |
The embodiments disclosed relates to a method and a network node that estimates a signal power and/or noise power of a received reference signal. The receiving node may operate in a communications system applying frequency division multiplexing. An assumption is that the channel frequency responses, on adjacent subcarriers of the communications system are equivalent or constant. The method comprising receiving a reference signal comprising a first reference signal from a first wireless terminal and a second reference signal from a second wireless terminal By using this assumption it is possible to combine first and second reference signal in order to estimating the signal power and/or noise power of a received reference signal without a conventional channel estimation technique. |
