摘要： A method performed by a first radio node to select a Listen-Before-Talk, LBT, method based on a type of information to be transmitted in a radio channel in unlicensed spectrum. The first radio node performs an LBT using the selected LBT method. When the information is data, the method includes always deferring transmission until: A) after completion of a first period of observation, an outcome of at least a second period of observation is that the channel is idle, or B) an outcome of a first period and one or more defer periods is that the channel is idle. When the information is control or management information, the selected method includes allowing transmission immediately after an outcome of the first period is that the channel is idle. A duration of the first period provides priority to the control or management information over data.

摘要： A transmitting node and a method performed by a transmitting node for performing data transmissions to at least one receiving node on a radio channel in a wireless communications network. First, the transmitting node sets at least two contention window sizes. The at least two contention window sizes are separately determined based on information associated with the least one receiving node. Then, the transmitting node defers a first transmission of data to the at least one receiving node for a first period and also defers at least one second transmission of data to the at least one receiving node Further, the transmitting node performs a first or at least one second transmission of data to the at least one receiving node when an outcome of a corresponding first and at least second periods of observation of the radio channel, respectively, is that the radio channel is idle.

摘要： A method, system and apparatus for low complexity intercarrier interference (ICI) compensation algorithms and cyclic block phase tracking reference signal (PTRS) sequence design are disclosed. According to one aspect, a method in a network node includes generating a PTRS, having a PTRS sequence that is configured to lower a complexity of an ICI compensation algorithm. According to another aspect, a method in a wireless device (WD) includes determining an ICI compensation algorithm based at least in part on a PTRS having a PTRS sequence, and applying the determined ICI compensation algorithm to compensate for ICI.

摘要： A network node is configured to communicate with a wireless device. The network node includes a radio interface and processing circuitry configured to transmit a configuration of a set of reference signals via RRC signaling to the wireless device. The radio interface and processing circuitry are further configured to transmit a downlink control information, DCI, that triggers the set of reference signals in multiple slots to the wireless device, where each set of reference signal is confined to OFDM symbols within a slot. In some embodiments, the DCI includes a field which indicates a reference signal set combination ID. In further embodiments the reference signal set combination ID indicates a list of RS set IDs. A method for a network node, a wireless device and a method for a wireless device are also provided.
