摘要
下一代移动通信系统对频谱有效性和功率有效性提出了更高的要求,在现有的蜂窝网结构中引入中继的协作式通信被认为是高速率高覆盖要求下最可行的改进。中继辅助协同通信网与传统蜂窝网相比在覆盖效率、运营成本以及传输容量3方面具有优势。中继辅助通信网络主要有3种典型的传输模型:三终端传输模型、两跳多中继并行传输模型、多跳多中继网络传输模型。中继辅助通信技术已在WiMAX、WIN-NER和3GPP等通信标准中得到深入研究,具有极为广阔的应用前景。
To facilitate the demand for a higher spectrum and power efficiency arising from the next-generation mobile communication system, the introduction of relay-aided cooperative communication into the existing cellular infrastructure is considered the most practical improvement under high rate and coverage. In comparison with the legacy cellular network, relay-aided cooperative communication network enjoys relative advantages over the following three aspects, namely coverage efficiency, operation cost and transportation capacity. Transportation of relay-aided cooperative network falls into three typical models： three terminal model, two-hop multi-relay parallel model, and multi-hop multi-relay model. For the extensive perspective of relay-aided cooperative communication in application, a profound research has been carried out in communication standards as WiMAX, WINNER and 3GPP, etc.
