    Abstract: The subject technology provides for performing clear channel assessment (CCA) in LTE-U. Transmissions may be monitored in a resource reserved for CCA. An energy of the transmissions is detected over a shorter duration than an assigned slot in the resource reserved for CCA. A beacon may be transmitted in a slot assigned to a wireless entity for CCA in response to detecting a clear channel based on the monitoring. In another aspect, a beacon transmission for CCA and a timing for the monitoring are adapted in response to detecting the transmissions for a consecutive number of CCA periods. Further, the subject technology provides for adjusting to a maximum power for transmission of a beacon in a slot assigned to a mobile station for CCA in response to detecting a clear channel based on the monitoring.

    Abstract: When enabled with common reference signal interference cancellation, a user equipment (UE) may still compute a channel state feedback value with consideration of any canceled interfering neighboring signals. When the neighboring cells are determined to be transmitting data during the time for which the channel state feedback value is being computed, the UE is able to derive the channel state feedback value considering those canceled interfering signals. The UE determines whether each neighboring cell is transmitting during the designated time either by obtaining signals that indicate the transmission schedule of the neighboring cells or by detecting the transmission schedule, such as based on the power class of the neighboring cells. If the UE determines that the neighboring cells are transmitting data during this time period, the UE will compute the channel state feedback value including consideration of the canceled interfering signals.

    Abstract translation: 当使用公共参考信号干扰消除时，用户设备（UE）仍可以考虑任何取消的干扰相邻信号来计算信道状态反馈值。 当在正在计算信道状态反馈值的时间内确定相邻小区正在发送数据时，UE能够导出考虑到那些被消除的干扰信号的信道状态反馈值。 UE通过获得指示相邻小区的传输调度的信号或者通过基于相邻小区的功率等级来检测传输调度来确定在指定时间期间每个相邻小区是否正在发射。 如果UE在该时间段期间确定相邻小区正在发送数据，则UE将计算包括考虑被消除的干扰信号的信道状态反馈值。

    Abstract: Techniques for estimating and reporting channel quality indicator (CQI) are disclosed. Neighboring base stations may cause strong interference to one another and may be allocated different resources, e.g., different subframes. A UE may observe different levels of interference on different resources. In an aspect, the UE may determine a CQI for resources allocated to a base station and having reduced or no interference from at least one interfering base station. In another aspect, the UE may determine multiple CQI for resources of different types and associated with different interference levels. For example, the UE may determine a first CQI based on at least one first subframe allocated to the base station and having reduced or no interference from the interfering base station(s). The UE may determine a second CQI based on at least one second subframe allocated to the interfering base station(s).
