    摘要： According to some embodiments, a method performed by a network node comprises receiving a plurality of radio signal samples; estimating parameters for a first hypothesis function, the first hypothesis function hypothesizing that that the plurality of radio signal samples only contains background noise; estimating parameters for a second hypothesis function, the second hypothesis function hypothesizing that that the plurality of radio signal samples contains background noise plus one or more radio pulses; performing a log-likelihood ratio test for the first hypothesis function and the second hypothesis function; and based on the log-likelihood ratio test, determining whether a radio pulse is present in the plurality of radio signal samples.

    摘要： The present disclosure relates to transmitting synchronization signals and in particular to so called beam sweep. In particular the disclosure relates to methods for providing synchronization using synchronization sequences that are transmitted at different points in time. The disclosure also relates to corresponding devices and computer programs. A method in a network node, for transmitting synchronization sequences of a synchronization signal to one or more receiving wireless devices, comprises determining multiple synchronization sequences, such that each synchronization sequence comprises a respective timing indication, whereby each synchronization sequence enables determination of a time of an event in a receiving wireless device and transmitting the synchronization sequences to the one or more wireless devices, at different points in time.

    摘要： The present disclosure presents a method performed in a first node in a wireless communication system, of accessing a shared channel for transmission from the first node to at least one second node. The method comprises the step of receiving, from a third node a pilot signal announcing reception in the third node, wherein the pilot signal comprises information enabling estimation of a channel response from the first node to the third node; estimating, using the pilot signal, a channel response from the first node to the third node and predicting, based on the estimated channel response, an interference level at the receiver of the third node of a directive transmission from the first node to the second node; and accessing the shared channel based on the predicted interference level.
