In a wireless system, by pooling distributed users to form a virtual multi-antenna system for joint transmission, the overall quality of the communication can be greatly improved. To reduce excessive overhead associated with large-scale user cooperation, the number of participating users must be well controlled. In this paper, the authors consider the problem of properly selecting a subset of users (from potentially a large number of candidates) to form the virtual multi-antenna system, while at the same time designing their joint transmission strategies.
