英文摘要	This paper presents a novel modulation and coding scheme (MCS) selection method to optimize the performance of Voice over Internet Protocol (VoIP) semi-persistent scheduling in Long Term Evolution (LTE) downlink. In VoIP traffic, the packet length little changes during a certain period and the cost of resource for the packet is related to this length. We exploit the characteristics and propose to select a more reliable MCS with the same amount of resource to be allocated. This method can reduce the block error ratio (BLER) at the same time satisfy VoIP Quality-of-Service (QoS) requirements. Through system level simulations, the proposed MCS selection criterion is proved to yield nearly 15% capacity gain in LTE VoIP system compared with the conventional method.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000305092100047&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Computer Science, Hardware & Architecture; Engineering, Electrical & Electronic; Telecommunications; EI; CPCI-S(ISTP); 0
