Ikirangantego:
● Ikorera kumurongo mugari wa bande kuva kuri sub-1GHz kugeza mmWave (> 24 GHz)
● Koresha imirongo mito <1 GHz, imirongo yo hagati 1-6 GHz, hamwe na bande ndende mmWave 24-40 GHz
● Sub-6 GHz itanga ubuso bwagutse bwa macro selile, mmWave ituma utugari duto twoherejwe
Ibiranga tekinike:
Gushyigikira umuyoboro mugari kugeza kuri 400 MHz ugereranije na 20 MHz muri LTE, byongera imikorere yikigereranyo
Gukoresha tekinoroji igezweho ya antenna nka MU-MIMO, SU-MIMO, no kumurika
● Guhuza imihindagurikire y'ikirere hamwe na precoding yibanda ku mbaraga zerekana ibimenyetso mu byerekezo bimwe na bimwe kugirango tunoze ubwishingizi
Scheme Gahunda yo guhinduranya igera kuri 1024-QAM yongerera igipimo cyimibare ugereranije na 256-QAM muri 4G
Mod Guhindura imihindagurikire y'ikirere hamwe na coding ihindura modulation na code ya code ukurikije imiterere y'umuyoboro
Numubare mushya wa OFDM numerologiya hamwe na subcarrier intera kuva 15 kHz kugeza 480 kHz iringaniza hamwe nubushobozi
● Kwiyitirira TDD subframes ikuraho ibihe byo kurinda hagati ya DL / UL guhinduranya
Procedures Uburyo bushya bwimiterere yuburyo nkuburyo bwateganijwe bwo gutanga inkunga butezimbere ubukererwe
Gukata imiyoboro ya nyuma-iherezo itanga QoS itandukanye ivura serivisi zitandukanye
Network Imiyoboro ihanitse yububiko hamwe na QoS urwego rwujuje ibisabwa bya eMBB, URLLC, na mMTC ikoresha imanza
Muri make, NR itanga iterambere ryinshi kuri LTE muburyo bworoshye, umurongo mugari, guhinduranya, kumurika, no gutinda kugirango ushyigikire serivisi za 5G.Nibikorwa fatizo byindege ya tekinoroji ituma 5G yoherezwa.
Igitekerezo gishyushye cyo kugurisha cyihariye cyo gushungura, gushungura hasi, gushungura hejuru, gushungura hejuru no kuyungurura bikoreshwa cyane mubisabwa 5G NR.Kubindi bisobanuro, nyamuneka sura urubuga: www.concept-mw.com cyangwa utwoherereze:sales@concept-mw.com
