摘要： According to some embodiments, a method for use in a wireless device of acquiring system information in a frequency-hopping network comprises obtaining an indication that the wireless device is configured for frequency hopping among a plurality of frequency channels. At least one of the plurality of frequency channels is a discovery channel. The discovery channel includes one or more dense discovery signals. A dense discovery signal is denser than a corresponding discovery signal included in the non-discovery channels of the plurality of frequency channels. The method further comprises tuning a radio receiver of the wireless device to the discovery channel, and acquiring system information using the one or more dense discovery signals. For example, a discovery signal (e.g., NPSS, NSSS, NPBCH, etc.) of the non-discovery channel may include one occurrence per frame and the corresponding discovery signal of the discovery channel includes more than one occurrence per frame.

摘要： There is disclosed a method, implemented in a wireless transmitter associated with license assisted access wireless communications between the wireless transmitter and a wireless receiver. The licensed assisted access wireless communications comprise communications using both a licensed wireless spectrum associated with a primary cell and an unlicensed wireless spectrum associated with a secondary cell. The method comprises determining whether a secondary cell channel between the wireless transmitter and the wireless receiver is idle, the secondary cell channel being associated with the unlicensed wireless spectrum of the secondary cell; and if the secondary cell channel is idle, subsequently transmitting a confirmation signal from the wireless transmitter to the wireless receiver via the secondary cell, the confirmation signal alerting the wireless receiver to the commencement of valid data transmissions from the wireless transmitter via the secondary cell. There are also disclosed further related methods and devices.

摘要： Systems and methods relating to Listen before Talk (LBT) procedures suitable for, e.g., License Assisted Access (LAA) to an unlicensed frequency spectrum or Long Term Evolution Unlicensed (LTE-U) are disclosed. In some embodiments, a method of operation of a node of a cellular communications network comprises performing a LBT procedure for an observed channel in an unlicensed frequency spectrum. The LBT procedure defers at least one Clear Channel Assessment (CCA) slot such that the LBT procedure concludes at or near a desired starting point for a transmission. The at least one CCA slot comprises at least one of a first CCA slot of the LBT procedure, one or more intermediate CCA slots of the LBT procedure, and a final CCA slot of the LBT procedure. The method further comprises performing the transmission on the observed channel upon completion of the LBT procedure.

摘要： A method performed by a first radio node (101) to select (1401) an LBT method based on a type of information to be transmitted in a radio channel (142) in unlicensed spectrum. The first radio node (101) performs (1402) an LBT with the selected LBT method. When the information is data, the method comprises always deferring (1502) 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 (142) is idle, or B) an outcome of a first period and one or more defer periods is that the channel (142) is idle. When the information is control or management information, the selected method comprises allowing transmission immediately after an outcome of the first period is that the channel (142) is idle. A duration of the first period provides priority to the control or management information over data.

摘要： In one aspect, the teachings herein describe an enhanced Reference Signal, RS, that is designed to be available for transmission in any symbol of a subframe. The enhanced RS may be an enhanced Sounding Reference Signal, SRS, or an enhanced DeModulation Reference Signal, DMRS. The enhanced RS provides an advantageous mechanism for channel capture in Listen- Before-Talk, LBT, scenarios, because subsequent to performing a successful Clear Channel Assessment, CCA, a node can begin transmitting the enhanced RS, to thereby capture the channel. The node can then transition into an actual data transmission on the channel according to whatever timing constraints are associated with the data transmission. In at least one embodiment, the enhanced RS is used for capturing an uplink channel on an LTE carrier operated in unlicensed spectrum, as part of a License Assisted Access, LAA, configuration.
摘要翻译：在一个方面，本文的教导描述了被设计为可用于在子帧的任何符号中传输的增强参考信号RS。增强型RS可以是增强型探测参考信号SRS或增强型解调参考信号DMRS。增强型RS为Listen-Before-Talk，LBT场景中的信道捕获提供了有利的机制，因为在执行成功的空闲信道评估CCA之后，节点可以开始传输增强型RS，从而捕获信道。然后根据与数据传输相关的任何时间限制，节点可以转换到信道上的实际数据传输。在至少一个实施例中，增强RS用于捕获在未授权频谱中操作的LTE载波上的上行链路信道，作为许可协助接入LAA配置的一部分。
