Abstract
A wireless communication system comprises a source node, a destination node, and a plurality of half-duplex relay nodes disposed between the source node and the destination node. The half-duplex relay nodes are configured in two disjoint paths each comprising an equal number of hops from the source node to the destination node. The source node is configured to alternately transmit information via the two disjoint paths in alternating time slots, and the destination node is configured to alternately receive information via the two disjoint paths in alternating time slots.
Claims20
A wireless communication node, comprising:
- a processor and memory collectively encoding instructions that when executed by the processor, cause the wireless communication node to:
- identify a current time slot as an odd time slot or an even time slot;
- and
- in response to identifying the current time slot as an odd time slot or an even time slot, transmit a source message to a corresponding odd-time relay group or an even-time relay group during the current time slot,
- wherein each of the odd-time relay group and the even-time relay group comprises a different set of half-duplex relay nodes disposed between the wireless communication node and a destination node.
A method of operating a wireless communication node, comprising:
- identifying a current time slot as an odd time slot or an even time slot;
- and
- in response to identifying the current time slot as an odd time slot or an even time slot, transmitting a source message to a corresponding odd-time relay group or an even-time relay group during the current time slot,
- wherein each of the odd-time relay group and the even-time relay group comprises a different set of half-duplex relay nodes disposed between the wireless communication node and a destination node.

- wherein each of the odd-time relay group and the even-time relay group comprises a different set of half-duplex relay nodes disposed between the wireless communication node and a source node that produced the source message.
