    • In one embodiment, a device in a frequency hopping communication network transmits responsive beacon messages based on adaptive types of responsive beacon message transmission based on a number of received beacon requests within a given time period: the number below a threshold results in synchronized unicast messages; the number above the threshold results in unsynchronized broadcast messages. In another embodiment, the device suppresses unsolicited beacon message transmission based on a density-aware redundancy count of other unsolicited beacon message transmissions from neighboring devices. In another embodiment, the device may transmit unsolicited beacon messages according to an adaptive interval based on stability of the network. In another embodiment, the device may suppress transmission of a beacon request to join the communication network based on a density-aware redundancy count of other beacon requests from neighboring devices, and transmits beacon requests at an adaptive interval that increases in response to each unanswered beacon request.
    • 在一个实施例中,跳频​​通信网络中的设备基于在给定时间段内的接收到的信标请求的数量,基于自适应类型的响应信标消息传输来发送响应信标消息:低于阈值的数量导致同步的单播消息; 超过阈值的数字导致不同步的广播消息。 在另一实施例中,设备基于来自相邻设备的其他未经请求的信标消息传输的密度感知冗余计数来抑制主动信标消息传输。 在另一个实施例中,设备可以基于网络的稳定性,根据自适应间隔发送未经请求的信标消息。 在另一个实施例中,设备可以基于来自相邻设备的其他信标请求的密度感知冗余计数来抑制加入通信网络的信标请求的传输,并以响应于每个未​​应答信标而增加的自适应间隔发送信标请求 请求。

    • A user equipment UE determines at least one first set SI of physical resource blocks PRBs, and detects downlink signaling within search spaces of set(s) SI. Through that downlink signaling the UE obtains a configuration for a downlink control channel, and that configuration indicates at least one second set S2 of PRBs and at least one search space specific for the UE which lies within S2. The UE utilizes the obtained configuration to monitor at least some of the search spaces of SI and the at least one search space specific for the UE of S2 for further downlink control signaling. Multiple implementations are detailed for how the UE gets SI. This invention is particularly useful for a configurable ePDCCH region in a stand-alone carrier where the UE is not able to get the new configuration from some other carrier such as a PCell whose configuration does not change.
    • 用户设备UE确定物理资源块PRB的至少一个第一集合SI,并且检测集合SI的搜索空间内的下行链路信令。 通过该下行链路信令,UE获得用于下行链路控制信道的配置,并且该配置指示PRB的至少一个第二组S2和位于S2内的UE特有的至少一个搜索空间。 UE利用所获得的配置来监视SI的搜索空间和针对S2的UE特定的至少一个搜索空间的另外的下行链路控制信令的至少一些。 详细说明了UE如何获取SI的多个实现。 本发明对于独立载波中的可配置ePDCCH区域是特别有用的,其中UE不能从诸如其配置不改变的PCell的其他载体获得新配置。

    • In one embodiment, a device in a frequency hopping communication network operate in a first mode according to a common broadcast schedule for the network that simultaneously overlays a first configured portion of all independently determined unicast listening schedules in the network. In response to determining a power outage condition, the device switches to operation in a power outage mode where the common broadcast schedule for the network in the power outage mode simultaneously overlays a second configured portion of all independently determined unicast listening schedules in the network, the second configured portion greater than the first configured portion. In one embodiment, the device broadcasts one or more power outage notifications (PONs) in response to determining the power outage condition as a reduction of a main power supply at the device. In another embodiment, the device receives a PON while powered as the power outage condition.
