    • 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。
