Two cooperative relaying protocols are presented and analyzed. The first emphasizes PHY cooperation via synchronized transmissions and distributed space-time coding from the Base Station (BS) and Relay Station (RS) to the User Equipment (UE) during the protocol's cooperative phase. The second protocol emphasizes MAC cooperation using different MAC flows from the BS and RS to the UE during the cooperative...
We introduce a collaboration-driven approach to the sharing of the available bandwidth in wireless ad hoc networks, which we call many-to-many communication, that allows concurrent multi-packet transmissions (MPTs) and multi-packet receptions (MPRs). Many-to-many communication also permits one-time multi-copy relaying of the same packet, which reduces the packet delivery delay compared to single-copy...
