A half-duplex relay channel consisting of two relays in a diamond topology is studied. In contrast to full-duplex systems, it is shown that time should be optimally allocated among different states. In contrast to the classical three-node relay channel, it is shown that spatial reuse can be utilized to allow communication without interference. Both achievable rate and upper bound on capacity are studied. Several communication schemes such as multihop with spatial reuse, scale-forward, broadcast… CONTINUE READING
