Cooperative Receiving Scheme for Downlink of Cellular Systems

In wireless mobile cellular systems, it has been popular for mobiles to support some short-range wireless communication protocols (SRWCPs)−Bluetooth, Zigbee, NFC (near field communication), etc. In this paper, we introduce a simple SRWCP-aided downlink cooperative receiving scheme. In the proposed scheme, a cluster is composed by some active mobiles which can be connected via SRWCPs, and then the base station transmits intermobile interleaved data to the active mobiles simultaneously. Each mobile merges its own received data with the handed-over data from partner mobiles in the cluster through SRWCPs. Since each mobile can use the data received from several independent wireless channels—channels between the base station and mobiles in the cluster, we can expect some diversity gain.
