Umsakazo Omusha we-5G (NR)

I-Spectrum:

● Isebenza kuzo zonke izinhlobo eziningi zama-frequency band kusukela ku-sub-1GHz kuya ku-mmWave (>24 GHz)
● Isebenzisa amabhendi aphansi <1 GHz, amabhendi aphakathi angu-1-6 GHz, kanye namabhendi aphezulu mmWave 24-40 GHz
● I-Sub-6 GHz inikeza ukumbozwa kwamaseli amakhulu endaweni ebanzi, i-mmWave ivumela ukuthunyelwa kwamaseli amancane

Izici Zobuchwepheshe:

● Isekela ama-bandwidth amakhulu esiteshi afinyelela ku-400 MHz uma kuqhathaniswa ne-20 MHz ku-LTE, okwandisa ukusebenza kahle kwe-spectral
● Isebenzisa ubuchwepheshe obuthuthukisiwe be-antenna eziningi njenge-MU-MIMO, i-SU-MIMO, kanye ne-beamforming
● Ukwakheka kwe-beamform okuguquguqukayo okune-precode kugxila emandleni esignali ezindleleni ezithile ukuze kuthuthukiswe ukumbozwa
● Izinhlelo zokushintshashintsha ezifika ku-1024-QAM zandisa amazinga aphezulu edatha uma kuqhathaniswa ne-256-QAM ku-4G
● Ukuguqulwa kwesimo okuguquguqukayo kanye nokubhala ikhodi kulungisa ukuguqulwa kwesimo kanye nezinga lokubhala ikhodi ngokusekelwe ezimweni zesiteshi
● I-numerology entsha ye-OFDM ekwazi ukukala enesikhala se-subcarrier kusuka ku-15 kHz kuya ku-480 kHz kanye nomthamo webhalansi
● Ama-subframe e-TDD azimele asusa izikhathi zokulinda phakathi kokushintsha kwe-DL/UL
● Izinqubo ezintsha zesendlalelo esibonakalayo njengokufinyelela kokunikezwa okulungiselelwe kuthuthukisa ukubambezeleka
● Ukusikwa kwenethiwekhi kusukela ekuqaleni kuze kube sekupheleni kunikeza ukwelashwa kwe-QoS okuhlukile kwezinsizakalo ezahlukahlukene
● Ukwakhiwa kwenethiwekhi okuthuthukisiwe kanye nohlaka lwe-QoS kuhlangabezana nezidingo ze-eMBB, URLLC, kanye nezimo zokusetshenziswa kwe-mMTC

Ngamafuphi, i-NR iletha ukuthuthuka okukhulu kune-LTE ekuguquguqukeni kwe-spectrum, i-bandwidth, i-modulation, i-beamforming, kanye ne-latency ukusekela izidingo zezinsizakalo ze-5G. Ubuchwepheshe obuyisisekelo bokuxhumana komoya obuvumela ukuthunyelwa kwe-5G.

Isihlungi se-notch esenziwe ngokwezifiso se-Concept esithengiswa kakhulu, isihlungi se-lowpass, isihlungi se-highpass kanye nesihlungi se-bandpass zisetshenziswa kabanzi ezinhlelweni zokusebenza ze-5G NR.
