Research Abstract

For ultra high speed packet mobile network, we have proposed a virtual cellular system. Multi-hop route construction algorithm and radio resource allocation are important technical issues of virtual cellular system. Our study is summarized below.
1. Study of multi-hop route construction of virtual cell
Multi-hop route construction algorithm based on the minimum transmit power criterion was proposed. To further reduce the route total transmit power, multi-hop maximal ratio combining (MHMRC) diversity was proposed and the power reduction by MHMRC diversity was evaluated by computer simulation. We also proposed a table-driven route reconstruction algorithm in order to reconstruct the multi-hop route rapidly when a link or port failure occurs.
2. Study on resource assignment of virtual cell
An on-demand channel assignment strategy, using the channel segregation dynamic channel allocation (CS-DCA) algorithm, was proposed for multi-hop link among mobile terminal~wireless port~central port. Due to decreased transmit power in the multi-hop links, the decreased interference leads to less blocking probability compared to present cellular network. A call is blocked when there is no channel available at one link over the multi-hop route. To avoid the call blocking, a relay skipping method was proposed. The impact of the proposed method on the blocking probability was evaluated.
3. Study on 2-hop virtual cell
In order to shift from an existing cellular system easily, the number of hops may be limited to 2. The impact of the distribution of wireless ports on the outage probability, the resource assignment algorithm and the throughput performance of 2-hop virtual cellular system were studied.
