    Abstract: The disclosure provides for a method of interference detection using adaptive energy detection in unlicensed spectrum. The method can include a first modem operating according to a first radio access technology (RAT) receiving a message from a network entity operating according to the first RAT. The first modem sends a detected energy level value to a second modem that is using a second RAT, where the detected energy level value is based at least on the measured energy level of the received message. The second modem adjusts an energy detection threshold based on the detected energy level value received from the first modem. In an aspect, the first modem receives messages from a plurality of network entities operating according to the first RAT, where the detected energy level value is determined based on measured energy levels of the plurality of received messages.

    Abstract: In an unlicensed band, different types of interference may be experienced by user equipments (UEs), and a serving evolved Node B (eNB) may not be aware of the interference types affecting a UE. Therefore, aspects presented herein provide UE assisted interference learning, in which the UE detects an interfering signal and reports information such as the interference level and properties of the interfering signal to a serving eNB. Another aspects presented herein provide for an eNB which receives, from one or more UEs, information indicating properties of each of at least one interfering signals experienced by the UEs, such as interference types affecting the UEs. The eNB further uses the information received from the UE, including the wireless technology type to determine the properties of its downlink transmission and the length of the contention window leading up to its downlink transmission.

    Abstract: Techniques for structured channel rasters for unlicensed spectrum are described. In an aspect, a first channel raster is identified, where the first channel raster is determined from a set of carrier frequencies and is used over an unlicensed or shared spectrum for a wireless wide area network (WWAN). The first channel raster is aligned with a second channel raster that is used over the unlicensed spectrum for a wireless local area network (WLAN). A frequency scanning may be performed by a user equipment (UE) or a network entity over the unlicensed spectrum for the WWAN using the first channel raster. In an aspect, the first channel raster is used over the unlicensed spectrum for the WWAN supported by the user equipment (UE) or the network entity.

    Abstract: In order to cancel any interference due to the second signal (e.g., from a non-serving cell) from a signal received at a UE, without receiving additional control information, the UE blindly estimates parameters associated with decoding the second signal. This may include determining a metric based on sets of symbols associated with the signals in order to determine parameters for the second signal, e.g., the transmission mode, modulation format, and/or spatial scheme of the second signal. The parameters for the signal may be determined based on a comparison of the metric with a threshold. When a spatial scheme and a modulation format is unknown, the blind estimation may include determining a plurality of constellations of possible transmitted modulated symbols associated with a potential spatial scheme and modulation format combination. Interference cancellation can be performed using the constellations and a corresponding probability weight.

    Abstract translation: 为了从UE接收到的信号中消除由于第二信号（例如，来自非服务小区）的任何干扰而不接收附加控制信息，UE盲目地估计与解码第二信号相关联的参数。 这可以包括基于与信号相关联的符号集来确定度量，以便确定第二信号的参数，例如第二信号的传输模式，调制格式和/或空间方案。 可以基于度量与阈值的比较来确定信号的参数。 当空间方案和调制格式未知时，盲估计可以包括确定与潜在的空间方案和调制格式组合相关联的可能传输的调制符号的多个星座。 干扰消除可以使用星座和相应的概率权重进行。
