5G Wailesi Yatsopano (NR)

Spectrum:

● Imagwira ma frequency angapo kuchokera pa sub-1GHz mpaka mmWave (>24 GHz)
● Imagwiritsa ntchito mabandi otsika <1 GHz, mabandi apakati 1-6 GHz, ndi mabandi apamwamba mmWave 24-40 GHz
● Sub-6 GHz imapereka kufalikira kwa ma cell ambiri, mmWave imathandizira kutumiza ma cell ang'onoang'ono.

Zaukadaulo:

● Imathandizira ma bandwidth okulirapo mpaka 400 MHz poyerekeza ndi 20 MHz mu LTE, kukulitsa luso la mawonekedwe
● Imathandizira ukadaulo wapamwamba wa tinyanga tambirimbiri monga MU-MIMO, SU-MIMO, ndi kuwala
● Kusintha kwa kuwala kokhala ndi ma precoding kumayang'ana mphamvu ya ma siginecha mbali zina kuti ziwongolere kufalikira
● Ma module osinthira mpaka 1024-QAM amachulukitsa kuchuluka kwa data poyerekeza ndi 256-QAM mu 4G
● Kusintha kwa ma adaptive ndi ma code amasintha kusinthasintha ndi kuchuluka kwa ma code potengera momwe tchanelo chilili
● Nambala zatsopano za OFDM zokhala ndi mipata yochokera ku 15 kHz mpaka 480 kHz ndi mphamvu zake.
● Mawonekedwe a TDD odzipangira okha amachotsa nthawi zolondera pakati pa kusintha kwa DL / UL
● Njira zatsopano zosanjikiza thupi monga mwayi wokhazikika wa grant zimathandizira kuchedwa
● Kudula kwapaintaneti kumapeto kumapereka chithandizo cha QoS chosiyana pa mautumiki osiyanasiyana
● Kamangidwe kapamwamba ka netiweki ndi ndondomeko ya QoS zimakwaniritsa zofunikira za eMBB, URLLC, ndi mMTC.

Mwachidule, NR imapereka kusintha kwakukulu pa LTE mu kusinthasintha kwa spectrum, bandwidth, modulation, beamforming, ndi latency kuthandizira zofuna za 5G.Ndilo ukadaulo woyambira wa air interface womwe umathandizira kutumizidwa kwa 5G.

Zosefera zotentha za Concept, zosefera za lowpass, zosefera za highpass ndi bandpass zimagwiritsidwa ntchito kwambiri pamapulogalamu a 5G NR.Kuti mudziwe zambiri, chonde pitani pa intaneti yathu: www.concept-mw.com kapena mutitumizireni imelo:sales@concept-mw.com
