摘要： There is disclosed a method of estimating frequency offset of a received signal in a terminal apparatus operating in a wireless communication system. The method comprises a) determining a phase change between a first and a second reference symbol of the received signal, wherein the time distance t between the first and the second reference symbols is associated with an observation frequency f such that f =1/ t ; b) determining a preliminary frequency offset Δ f based on the determined phase change, wherein the preliminary frequency offset Δ f form a frequency offset hypothesis Δ f h ; c) decoding at least a part of the received signal, with application of the frequency offset hypothesis Δ f h , to a decoded signal; d) determining whether the decoded signal is a successful decoding, wherein if the decoded signal is a successful decoding, determining the frequency offset hypothesis Δ f h to be the estimated frequency offset, and if the decoded signal is not a successful decoding, adjusting the frequency offset hypothesis Δ f h , by an integer n times the observation frequency f such that Δ f h = Δ f + n · f, where n ∈ [+/- 1, 2, 3, ...], and repeating steps c) and d). Computer program, frequency controller, and terminal apparatus are also disclosed.

摘要： The present disclosure relates to a method of a first radio device (401; 402) using a first radio access technology, RAT, (405) for communication with a second radio device (401; 402). The method comprises listening for any transmission in a frequency channel of an unlicensed radio frequency band. The method also comprises determining whether the channel is idle. The method also comprises transmitting a first radio message on the channel in accordance with a second RAT (406), different than the first RAT (405). The method also comprises determining transmission properties for a message to be transmitted on the channel in accordance with the first RAT, based on the determining of whether the channel is idle. The method also comprises transmitting a second radio message on the channel, to the second radio device and in accordance with the first RAT using the determined transmission properties.

摘要： A technique for cell signature determination in a cellular communication network is provided. A method implementation of this technique comprises the steps of providing a set of hypothesis signals, each hypothesis signal including a signature hypothesis, receiving a composite signal including a first signal portion carrying a first signature from a first cell and a second signal portion carrying a second signature from a second cell, wherein the first signal portion and the second signal portion overlap at least partially in time, and obtaining a correlation result by correlating the composite signal with each hypothesis signal. After the first signature has been determined, a set of phantom signatures associated with the first signature is provided. The phantom signatures represents artifacts from the first signal portion in the correlation result. Finally, the second signature is determined based on the correlation result taking into account the set of phantom signatures associated with the first signature.
