Joint link-and-user scheduling for buffer-aided relaying system with adaptive rate transmission
In this paper, we consider a relaying system which consists of a multiple-antenna source node (SN), M singleantenna destination nodes (DNs) and a multiple-antenna relay node (RN). The RN possesses a buffer and it is able to store the decoded message before retransmitting the message to the DNs....

| description | In this paper, we consider a relaying system which
consists of a multiple-antenna source node (SN), M singleantenna
destination nodes (DNs) and a multiple-antenna relay
node (RN). The RN possesses a buffer and it is able to store
the decoded message before retransmitting the message to the
DNs. We use the joint link-and-user scheduling method to maximize
the long term average achievable rate of a multiple-input
multiple-output (MIMO) relaying system. The optimal scheduling
criteria is obtained and a two-step approach is proposed to
implement it. In addition, we propose a rate allocation scheme
of the source-relay (S-R) link to preserve the flow conservation
constraint of each individual user. Furthermore, two reduced
complexity joint link-and-user scheduling methods which use
the zero forcing (ZF) beamforming in the relay-destination (RD)
link are investigated. It is shown that joint link-and-user
scheduling can significantly increase the average achievable rate
of the system. |
