Bi-directional relaying strategies for linear four-node wireless network are discussed in this paper. The system model is that linear four nodes want to realize the bi-directional information exchanges of two packets that are belong to two pairs of nodes respectively. Each node is equipped with single antenna, and operates in half-duplex model, and a transmission period consists of four slots. For this cooperative bi-directional relaying model, three relaying strategies are proposed as well as the analysis of achievable rate region.
