Introduction Cooperative transmission across multiple network nodes to the same MS can provide macro-diversity gain interference mitigation and spatial multiplexing gain which can lead to improved capacity and coverage. Cooperative transmission can be applied to both BS and RS depending on the user s location within the network and the type of network deployment. Cooperative relaying is one form of cooperative transmission. This contribution proposes the cooperative transmission function to be added to the overall IEEE 802.16m protocol structure. 2. IEEE 802.16m Protocol Structure with Cooperative Transmission Function Figure 1 shows the addition of the Cooperative Transmission Management functional block on the upper MAC and the interaction of the Cooperative Transmission Management function with other control plane functions for the processing of user data. Figure 1 Interaction between Cooperative Transmission Management Function with Other Control Plane Functions for the Processing of User Data Figure 2 shows the processing of MAC signaling associated with cooperative transmission operation. 2 IEEE C802.16m-07/306 Figure 2 Interaction between Cooperative Transmission Management Function with Other Control Plane Functions for the Processing of MAC Signaling Flow Associated with Cooperative Transmission 3. Conclusion and Recommendation Our recommendation is to include the cooperative transmission function into the IEEE 802.16m protocol structure as described in Section 2. 3
