Qualcomm很高兴地宣布,将与三星电子有限公司合作开发小型基站技术和产品,以提升移动网络的速度和容量。根据此次合作,三星将成为首批采用Qualcomm FSM99xx芯片,通过LTE-U来聚合授权频谱和非授权频谱的公司之一。FSM99xx芯片预计将在今年晚些时候进行部署。 

关于这项发布,有不少令人兴奋的事儿,而我们希望大家特别注意其中一点:随着3GPP Release 13规范即将完成,Qualcomm Technologies的FSM99xx芯片能让客户在近期通过LTE-U将LTE扩展到非授权频谱,同时支持授权辅助接入 (LAA)的软件升级路径。

LTE-LAA是3GPP Release 13规范的一个重要组成部分,该规范预计将于今年晚些时候完成。LAA与LTE-U类似,通过载波聚合将5GHz非授权频谱中的LTE与授权频段中的LTE相结合。LAA的最重要特性之一大概就是“Listen Before Talk”。 “Listen Before Talk”不仅是一句生活箴言,其实也是一项满足全球部分地区使用非授权频谱LTE监管要求的必需特性,这些地区包括了欧洲和日本等等。德国电信和Qualcomm Technologies, Inc.共同进行的全球首个OTA(over-the-air)LAA试验,已展现了移动运营商的受益之处。
