Abstract: The present disclosure describes methods and apparatus for beaconing within a wireless network based on an indication of distance. For certain example embodiments, in a wireless network in which a master device is a device configured to transmit a beacon within the wireless network, a first wireless communication device may determine, based on an indication of distance between two wireless communication devices, if the first wireless communication device is to act as a master device. For example, a wireless signal may be received. Based at least partially on the received wireless signal, an indication of distance between two wireless communication devices in a wireless network may be obtained. And based at least partially on the obtained indication of distance between the two wireless communication devices, it may be determined if a first wireless communication device is to act as a master device within the wireless network.

Abstract: A wireless communication system includes a first wireless access point, and a first set of at least one first station in wireless communication with the first wireless access point. The first wireless access point controls power for communications with a first station in the set of at least one first station. The first wireless access point may control power in a time-domain, announcing a power level for use during a time window. The first wireless access point may control power levels in a frequency-domain, announcing different power levels for different frequency subchannels within a frequency channel. The wireless communication system may further include an additional wireless access point, and an additional set of at least one additional station in wireless communication with the additional wireless access point. The first and additional wireless access points control power to avoid interference between the first and additional wireless access points.

Abstract translation: 无线通信系统包括第一无线接入点和与第一无线接入点无线通信的至少一个第一站的第一组。 第一无线接入点控制与至少一个第一站的集合中的第一站的通信的电力。 第一个无线接入点可以控制时域中的功率，在时间窗口内宣布使用功率电平。 第一无线接入点可以控制频域中的功率电平，通知频率信道内的不同频率子信道的不同功率电平。 无线通信系统还可以包括附加的无线接入点和与附加无线接入点进行无线通信的至少一个附加站的附加集合。 第一和另外的无线接入点控制电力以避免第一和另外的无线接入点之间的干扰。
