    • A method and system locates a position of a transceiver in a cooperative relay network of nodes. A primary node broadcasts a range request (RREQ) message. A target node, in response to receiving the RREQ message, broadcasts a range reply (RREP) message, wherein the RREP message includes a time difference between receiving the RREQ message and broadcasting the RREP message. A secondary node, in response to receiving the RREQ message and the RREP message, broadcasts a range data (RDAT) message, wherein the RDAT message includes a time difference between receiving the RREQ message and the RREP message. Then, a position solver can determine a location of the target node based on the time differences in the RREP message and the RDAT message.
    • 方法和系统将收发器的位置定位在节点的协作中继网络中。 主节点广播范围请求(RREQ)消息。 响应于接收到RREQ消息,目标节点广播范围应答(RREP)消息,其中RREP消息包括接收RREQ消息和广播RREP消息之间的时间差。 响应于接收到RREQ消息和RREP消息,辅助节点广播范围数据(RDAT)消息,其中RDAT消息包括接收RREQ消息和RREP消息之间的时间差。 然后,位置求解器可以基于RREP消息和RDAT消息中的时间差来确定目标节点的位置。

    • A network includes a master node (master) and a set of slave nodes (slaves). The network uses orthogonal frequency-division multiplexing (OFDM) and time division multiple access (TDMA) symbols on sub-carriers. During a first downlink transmission from the master to the set of slaves using downlinks and all of the sub-carriers, a broadcast polling packet including data packets for each slave and sub-carrier assignments for the slaves is broadcast. Each slave transmits simultaneously to the master using uplinks and the assigned sub-carriers, a first response packet after receiving the broadcast polling packet. The master then broadcasts using the downlinks and all of the sub-carriers, a group acknowledgement packet, wherein the broadcast polling packet, the response packet, and the group acknowledgement packet include one superframe in one communication cycle, and wherein the broadcasting on the downlinks and the transmitting on the uplinks are disjoint in time.
    • 网络包括主节点(主节点)和一组从节点(从节点)。 该网络在子载波上使用正交频分复用(OFDM)和时分多址(TDMA)符号。 在使用下行链路和所有子载波从主机到从机组的第一次下行链路传输期间,广播包括用于每个从机的数据分组的广播轮询分组和用于从机的子载波分配。 每个从设备使用上行链路和分配的子载波同时发送到主设备,第一响应分组在接收到广播轮询分组之后。 然后主机使用下行链路和所有子载波,一组确认分组广播,其中广播轮询分组,响应分组和组确认分组在一个通信周期中包括一个超帧,并且其中在下行链路上进行广播 并且在上行链路上的发送在时间上是不相交的。

    • An apparatus, system, method and computer program product for secure ranging between at least two devices in radio communications with each other. In particular, an apparatus, system, method and computer program product for secure ranging between at least two devices communicating via ultra wideband (UWB) protocols. Either ternary-IR or time-hope-IR sequences are used for ranging and security. A first device transmits a range packet. A second device responds to the range packet after a delay time known only to the first and second devices. The delay time can be selected randomly by either to the first device or the second device and made known to the other device in an encrypted notification packet.
