Cov khoom siv dab tsi uas xav tau rau 5G?
1. Cov kav hlau txais xov loj: Cov MIMO Loj heev tau pom tias yog ib lub thev naus laus zis tseem ceeb ntawm 5G, thiab nws tsuas yog lub tshuab thev naus laus zis nkaus xwb uas tuaj yeem txhim kho qhov system muaj peev xwm kaum lossis ib puas. Loj-loj ntau lub kav hlau txais xov tshuab tuaj yeem txhim kho spectrum kev siv hluav taws xob thiab kev siv hluav taws xob kom muaj txiaj ntsig los ntawm ntau qhov sib txawv (chaw sau, lub sijhawm sau npe, zaus ntau zaus, polarization domain, thiab lwm yam).
2. Kev nkag mus siv tshiab thev naus laus zis: ntau txoj hauv kev nkag ntawm eMBB scene yuav tsum ua raws li cov txheej txheem ntau orthogonal nkag mus, thiab tsis-orthogonal ntau cov thev naus laus zis tau txwv rau uplink scene ntawm mMTC. eMBB' s siv ntau lub tshuab thev naus laus zis tuaj yeem siv DFT-S-FDMA thiab OFDMA. Huawei SCMA, ZTE MUSA thiab Datang' s PDMA yuav sib tw rau mMTC' s uplink ntau txoj hauv kev daws teeb meem xyoo 2017.
3. Qhov kev sib txuas xov tooj cua siab yuav tsum tau teeb tsa zoo ib yam: lub neej yav tom ntej 5G system yuav raug taw qhia mus rau tag nrho cov xaim hluav taws xob qis dua 6GHz thiab siab dua 6GHz kom nkag siab zoo hauv' s xav tau rau lub peev xwm, kev pov hwm, kev ua haujlwm thiab lwm sib nrauj. Tam sim no, cov kab hluav taws xob tsawg tsawg hauv qab 6GHz yog dhau ntawm kev hla, thiab cov kab ke loj hauv qab 6GHz tsis dhau. Qhov no yog qhov teeb meem loj tshaj plaws rau loj kawg 5G spectrum xav tau yav tom ntej.
4. Lub tshuab hluav taws xob ntau lub tshuab tshiab: 5G tshiab huab cua sib cuam tshuam ntau lub tshuab xa khoom tuaj yeem ua tiav cov lag luam xav tau ntawm lub Internet txawb thiab Internet ntawm yam. Muaj ntau ntau yam yuav tau txiav txim siab thaum xaiv hom tshiab yoj, nrog rau kev ua kom zoo dua, lub sijhawm qeeb, kev sib txuam ntau lub zog, kev siv hluav taws xob, kev ua yeeb yaj kiab uas nyob sib ze, thiab tus nqi siv. Txog tam sim no, peb qhov nrov tshaj plaws hauv kev sib tw thev naus laus zis hauv kev lag luam yog: F-OFDM, FB-OFDM thiab UF-OFDM.
5. Advanced coding thiab tes taws los piav: Ob qhov uplink thiab downlink cov ntaub ntawv raws ntawm eMBB scene siv hloov LDPC coding cov phiaj xwm; cov uplink tswj channel ntawm eMBB scene adopts Polar coding tswvyim; lub downlink tswj channel ntawm eMBB scene feem ntau yuav siv txoj cai coding Polar siv TBCC (tus Tsov tus tw tom qab) Txoj kev daws teeb meem) txheej txheem;
6. Puv-thev naus laus zis thev naus laus zis: Nws tuaj yeem pab cov khoom siv sib txuas lus kom xa tau thiab tau txais cov teeb liab rau hauv cov khoom siv ntau zaus tib lub sijhawm. Hauv txoj kev xav, nws tuaj yeem ua rau qhov kev ua haujlwm zoo dua ob npaug ntawm hom qub TDD lossis FDD, thiab nws kuj tseem tuaj yeem txo qhov kev xa mus kom kawg mus rau qhov kawg. Ncua thiab txo taw tes tshaj xo. Cov teeb meem tseem ceeb ntawm cov thev naus laus zis puv npo yog yuav ua li cas thiaj li muaj kev cuam tshuam thiab tshem tawm qhov kev cuam tshuam tus kheej muaj zog.
7. Kev sib koom tes ultra-ntom ntom ntuag: Kev sib koom tes txuas ntom ntom ntom ntom ntom ntaws hauv tshuab txuas tuaj yeem txhawb lub davhlau ya nyob twg kom ntes ntau spectrum hauv qee thaj chaw, thiab qhov kev ncua deb rau txhua qhov kis tau txuas ntxiv kuj tseem ze dua, uas txhim kho lub zog txuag thiab spectrum efficiency ntawm kev lag luam, thiab zoo heev txhim kho Lub cev muaj peev xwm, thiab ib txwm ua kom lub luag haujlwm sib koom nrog cov kev pabcuam ntawm ntau cov kev siv thev naus laus zis thiab qib kev tiv thaiv
8. Lub vev xaib tseem ceeb ntawm cov thev naus laus zis: Nrog kev kawm tiav qeeb ntawm software-txhais networking (SDN) thiab network ua haujlwm virtualization (NFV) thev naus laus zis, 5G networking technologies tuaj yeem ua tiav qhov sib cais ntawm kev tswj lub zog thiab xa mus rau lub zog, raws li lub network ntawm lub zog thiab lub cev decoupling ntawm cov chaw ua rau cov tswv yim txawj ntse thiab lub sijhawm tiag tiag xa tawm ntawm cov peev txheej, nrog rau cov kev xav tau thiab kev yoog raws kev sib txuas thiab sib txuas hauv network.
