第一版5G标准签署通过:涵盖低中高三频、手机2019年见

快科技 2017-12-21

  据Fierce Wireless报道,3GPP(移动通信的标准化机构)今天在葡萄牙首都里斯本正式签署通过了5G NSA(Non-Standalone,非独立组网)标准第一个版本。

  这意味着,硬件厂商的设备开发工作可以从现在开始了。

  按照3GPP规划,5G标准分为NSA和SA(Standalone独立组网)两种。其中5G NSA组网是一种过渡方案,主要以提升热点区域带宽为主要目标,没有独立信令面,依托4G基站和核心网工作,相对标准制定进展快些。

  SA标准计划于明年6月签署通过,比如中国移动牵头的版本也会在同期完成。

  由于标准文本本周晚些时候才能下载到,3GPP仅透露,在频谱上,5G NSA调用的阈值非常广泛,下到600~700MHz,上到50GHz(高通称之为毫米波)。

  根据工信部的方案,我国的5G承载频段是Sub 6GHz的中频,也涵盖在此次标准范围内。

  此前,网友曝光了一份高通/华为/Intel/三星的5G基带储备情况,进度和技术水平都比较类似。目前,高通确认首款5G手机2019年上半年推出,华为则是下半年。

  不出意外的话,5G的第一次较大规模的室内外商用将在明年的韩国平昌冬奥会上崭露头角。
