Abstract: Novel adaptive silencing schemes for device-to-device (D2D) discovery based on loading conditions in a discovery zone are disclosed herein. These adaptive silencing schemes can be used to mitigate interference and data collisions in networks where D2D connections can be formed. In some embodiments, a silencing factor is used to probabilistically determine whether a user equipment (UE) will transmit one or more D2D discovery signals in the discovery zone. Loading conditions in a current discovery zone can be estimated using several different approaches and metrics described herein. The silencing factor can be increased or decreased for a subsequent discovery zone based on the values of one or more of the metrics described herein for the current discovery zone.

Abstract translation: 本文公开了基于发现区域中的加载条件的针对设备到设备（D2D）发现的新型自适应消隐方案。 这些自适应消隐方案可用于减轻可形成D2D连接的网络中的干扰和数据冲突。 在一些实施例中，使用沉默因子概率地确定用户设备（UE）是否将在发现区域中发送一个或多个D2D发现信号。 可以使用本文描述的几种不同的方法和度量来估计当前发现区域中的加载条件。 可以基于本文为当前发现区域描述的一个或多个度量的值，为后续发现区域增加或减少沉默因子。
