MAC112C-0-HD-2-C/130-A-0/S05雖然離2016年還剩下不到100天,但雷鋒網(wǎng)還是很清楚記得,今年2月27日的時(shí)候,F(xiàn)DD-LTE牌照正式下發(fā),當(dāng)時(shí)的國內(nèi)的4G用戶也才剛剛破億。雖然這段時(shí)間以來,4G用戶猛增,目前已經(jīng)超過2.5億(全國移動(dòng)用戶達(dá)9.37億)。
MAC112C-0-HD-2-C/130-A-0/S05但考慮到過往的歷史,1G、2G、3G、4G之間的換代間隔時(shí)間分別為12年、10年、8年,我們有理由相信,從4G發(fā)展到5G可能需要6年時(shí)間。就是說5G還不是時(shí)候,但在實(shí)際中,已經(jīng)有一撥人急吼吼殺到5G的面前了,這其中就包括華為。
今年3月份,華為宣布,與日本最大的移動(dòng)通信運(yùn)營商N(yùn)TT DOCOMO合作,對5G空口(移動(dòng)通信網(wǎng)絡(luò)中,基站與移動(dòng)終端之間的接口)新技術(shù)進(jìn)行聯(lián)合測試。近日,華為兌現(xiàn)承諾,在成都成功開展了大規(guī)模的5G空口新技術(shù)的外場驗(yàn)證。
此次外場驗(yàn)證的是大規(guī)模MU-MIMO(Multi-User Multiple-Input Multiple-Output,即多用戶多入多出)技術(shù),在6GHz以下5G核心頻段宏蜂窩組網(wǎng)場景支持同時(shí)接入24個(gè)UE終端。而這次采用的是SCMA(稀疏碼多址接入)和F-OFDM(濾波的正交頻分復(fù)用)兩種新的5G空口基礎(chǔ)技術(shù)。
MAC112C-0-HD-2-C/130-A-0/S05結(jié)果表明,在100MHz帶寬下,單小區(qū)平均下行吞吐量達(dá)到1.34Gb/s,峰值下行吞吐量達(dá)到3.6Gb/s。對此,華為表示,本次測驗(yàn)展示了SCMA與F-OFDM的強(qiáng)大性能。
事實(shí)上,在5G核心頻段對5G空口新技術(shù)進(jìn)行外場驗(yàn)證是提升5G頻譜效率和網(wǎng)絡(luò)性能與可靠性的關(guān)鍵。由此,對于這次外場驗(yàn)證的成功,華為倍感“欣慰”。接下來,華為計(jì)劃在2018年與合作伙伴建設(shè)5G試驗(yàn)網(wǎng),2019年完成5G互操作測試,并于2020年率先實(shí)現(xiàn)5G商用。
雖然這看起來是一件很勵(lì)志的事情,不過,華為所“押注”最后結(jié)果是否如愿以償,讓華為引領(lǐng)5G標(biāo)準(zhǔn),拿下話語與專利主導(dǎo)權(quán)地位,實(shí)現(xiàn)5G稱霸之夢?
MAC112C-0-HD-2-C/130-A-0/S05我們都知道3G時(shí)代的空口核心技術(shù)是CDMA;4G的空口核心技術(shù)是OFDM。但是5G時(shí)代的會(huì)不會(huì)是華為這次測試的SCMA與F-OFDM兩種技術(shù)的其中一呢?目前還無法下定論,畢竟有關(guān)國際標(biāo)準(zhǔn)化組織已初步明確,2016年才正式啟動(dòng)標(biāo)準(zhǔn)研制。由此,華為的“5G夢”只能等待時(shí)間的檢驗(yàn)。
