    Abstract: A Radio Network Node (RNN) and a method for enabling an improved reception of Positioning Reference Signals (PRSs) at a communications device. The RNN and the communications device are operable in a wireless communications network. The RNN selects a first precoder and a second precoder for forming a first beam and a second beam, respectively, and obtains a precoding switching pattern relating to when the first precoder is to be applied to one or more first PRS symbols and when the second precoder is to be applied to one or more second PRS symbols. Further, the RNN transmits, to the communications device, the one or more first PRS symbols to which the first precoder is applied; and in accordance with the obtained precoding switching pattern, the RNN transmits, to the communications device, the one or more second PRS symbols to which the second precoder is applied.

  • Patent number: 10721047
    Abstract: In certain embodiments, a method includes generating a first signal and a second signal. The first signal includes at least one first sub-signal, and the second signal includes at least one second sub-signal. A subcarrier frequency spacing of the first sub-signal is M times as large as a subcarrier frequency spacing of the second sub-signal. The method further includes separately sending each first sub-signal and each second sub-signal. In a range of a first preset frequency apart from a reference subcarrier frequency, all the second sub-signals sent on a subcarrier corresponding to a subcarrier frequency whose difference from the reference subcarrier frequency is a non-integer multiple of the subcarrier frequency spacing of the first signal are zero signals. The reference subcarrier frequency is a subcarrier frequency of the first sub-signal adjacent to the second signal in a frequency domain.

    Abstract: A method, apparatus, and system are provided for facilitating positioning based on signal correlation function characteristic feedback. In an embodiment, the method may involve steps performed by a network node in communication with a wireless communication device (WCD) and a plurality of base stations. The network node receives, from the WCD, location information including position reference signal (PRS) correlation function characteristics of a cross-correlation between a received downlink signal and a transmitted PRS for each base station from the plurality of base stations. The network node determines a position of the WCD using the PRS correlation function characteristics. The WCD may initiate the transmission of the PRS correlation function characteristics on its own, or in response to a request to do so from the network node.
