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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 62 / 107,271, filed January 23, 2015, the subject matter of which is hereby incorporated by reference in its entirety. technical field [0003] The disclosed subject matter relates generally to telecommunications, and more specifically, to adaptive trunking schemes and virtual full-duplex trunking operations. Background technique [0004] In order to handle the exponential growth of wireless data traffic, it is expected that base stations or wireless access nodes will need to be deployed quite densely in the future. The feasibility of deploying wireless access nodes very densely is based on the existence of a backhaul network that can provide high data rate transfers to each individual access node in the network. From the standpoint of maximizing capacity, a fiber-based backhaul solution is likely to be the most ideal solution and most suitable for ne...
