5I-G Redcap ithobelana nemithetho ye-FDA? Lithini igama eliphelele le-5G RedCap?

5Inethiwekhi ye-G ifana nomkhawulokudonsa ophezulu kanye nokubambezeleka okuphansi, futhi isisetshenziswa kabanzi manje, kodwa i-bandwidth ephezulu yenethiwekhi ye-5G nayo iletha izinkinga, okungamatheminali ayinkimbinkimbi namadivayisi angenawaya, ukusetshenziswa kwamandla okukhulu, kanye nezindleko eziphezulu zemishini , ngakho kwezinye izimo ezingadingi umkhawulokudonsa omkhulu, inethiwekhi ekhona ye-5G ayiyona into engcono kakhulu.

Kulo mongo, 5UG RedCap wazalwa. Igama eligcwele le-RedCap lithi Amandla Ancishisiwe, okusho ngokwezwi nezwi ikhono elincishisiwe, okusho ukuthi kuwubuchwepheshe bokusekela imishini yenethiwekhi engasindi.

uhlu lwabakhiqizi be-redcap chipset

5I-G RedCap inezici ezilandelayo:

Izinti zemishini yesikhumulo zinezimbobo ezimbalwa zokwamukela nezokudlulisa

Sekela ukuxhumana kwe-full-duplex ne-half-duplex

Idivayisi idla amandla amancane

I-oda lokushintshashintsha eliphansi

umkhawulokudonsa ophezulu ophansi

Sekela izici ezonga amandla

Izici zobuchwepheshe ezingenhla ziwukwenza lula ubunkimbinkimbi bemishini yenethiwekhi kanye nemishini yokugcina, ukunciphisa izindleko zizonke zemishini, kanye nokunciphisa ukusetshenziswa kwamandla.

Izimo eziyinhloko ze-5G RedCap zihlanganisa:

Emkhakheni wezinzwa zezimboni: idatha eqoqwe ngu izinzwa ayidingi umkhawulokudonsa omkhulu ukuhlangabezana nesidingo;

Inkambu yokugada amavidiyo: ilungele izimo ezingadingi ividiyo yekhwalithi ephezulu futhi ezingadingi ukubambezeleka okuphezulu;

Emkhakheni wezinto ezigqokekayo: izidingo zomkhawulokudonsa wokudlulisa inethiwekhi aziphezulu, futhi isivinini esiningi singaphansi kuka-50Mbps;

Isivinini esiphansi kuya-maphakathi I-inthanethi Yezinto: I-bandwidth yayo nezidingo zokulibaziseka aziphezulu, kodwa idinga ukusetshenziswa kwamandla okuphansi, imishini elula, kanye nezindleko eziphansi;

Okwamanje, 5I-G Redcap isiqalile ukuhlolwa kokuqala. Kulindeleke ukuthi iqedele ukuqinisekiswa kobuchwepheshe kanye nokuvuthwa kwemishini engxenyeni yesibili yalo nyaka. Kuzoba nokusetshenziswa kwezinga elincane kwezentengiselwano ngonyaka ozayo bese kuthunyelwa ngezinga elikhulu ngonyaka olandelayo.

5G RedCap Wikipedia:
I-RedCap (Amandla Ancishisiwe, ikhono elincishisiwe) ubuchwepheshe be-5G obuchazwa yinhlangano yokumiswa kwe-3GPP futhi bungowesibani esisha se-NR sobuchwepheshe obusha. (NR encane).

Ukuzalwa kwe-RedCap

Ezinsukwini zokuqala ze-5G, ukugxila kwe-5G kwakugxile kakhulu kumkhawulokudonsa omkhulu kanye ne-latency ephansi. Nokho, ukuklanywa kwama-chips namatheminali okuqala e-5G kwakuyinkimbinkimbi kakhulu. Akukhona nje ukutshalwa kwezimali ku-R&D kakhulu, kodwa izindleko zamatheminali nazo zenze ukuthi kungamukeleki ezimweni eziningi zangempela zokusatshalaliswa.

Ngezimo eziningi zohlelo lokusebenza, izidingo zejubane ziphakathi, izidingo zokusebenza ziphakathi, izidingo zokusetshenziswa kwamandla ziphakathi, futhi izidingo zezindleko ziphakathi. Ungayithola kanjani ibhalansi phakathi kokusebenza nezindleko zalezi zidingo, futhi ingahlala ngokubambisana nokuthunyelwa kwenethiwekhi ye-5G? Ngaphansi kwalesi sikhalazo, I-RedCap yaba khona.

NgoJuni 2019, ku-3GPP RAN #84 umhlangano, I-RedCap yethulwe okokuqala njenge-Rel-17 Study Item (iphrojekthi yocwaningo).

NgoNdasa 2021, 3I-GPP igunyaze ngokusemthethweni i I-NR RedCap i-terminal standardization (Into Yomsebenzi) iphrojekthi.

NgoJuni 2022, 3I-GPP Rel-17 iqandisiwe, okusho ukuthi inguqulo yokuqala yezinga le-5G RedCap isungulwe ngokusemthethweni.

Izimo zohlelo lokusebenza lwe-RedCap

Phakathi kwamazinga amisiwe e-5G, zihloswe kakhulu ezinhlotsheni ezintathu zezimo zohlelo lokusebenza, okungukuthi:

1: I-Mobile Broadband Ethuthukisiwe (eMBB, I-Mobile Broadband Ethuthukisiwe)

2: Ukuxhumana Komshini Omkhulu Kakhulu (mMTC, Ukuxhumana Komshini Omkhulu Kakhulu)

3: Ukuxhumana okuthembeke kakhulu kanye nokubambezeleka okuphansi (I-URLLC, Ukuxhumana okuthembeke kakhulu kanye nokubambezeleka okuphansi)

Enye inkambu yohlelo lokusebenza efanele ukunakwa okujwayelekile Ukuxhumana Okubucayi Kwesikhathi (I-TSC, Ukuxhumana Okuzwela Isikhathi).

Ngesikhathi sokuthunyelwa kwamanethiwekhi e-5G, uma eMBB, mMTC, I-URLLC, kanye ne-TSC zonke zisekelwa kunethiwekhi efanayo, izokwanelisa izimo ezihlukahlukene zokuthunyelwa kwezicelo zemboni ye-IoT ngangokunokwenzeka.

Kunguqulo ye-3GPP Rel-16, ngezimo zokufaka izicelo ze-TSC, ukwesekwa kwenethiwekhi ezwela isikhathi (I-TSN, Inethiwekhi Ezwela Isikhathi) futhi 5G uhlelo ukuhlanganiswa kwethulwa:

1. Emkhakheni wezinzwa zezimboni: 5Uxhumano lwe-G seluphenduke umsunguli wegagasi elisha le-inthanethi yezimboni kanye nokwenza idijithali, engasebenzisa amanethiwekhi kalula, ngcono ukusebenza kahle kokukhiqiza, ukunciphisa izindleko zokulungisa nokuqinisekisa ukuphepha kokusebenza. Ezimweni ezinjalo zohlelo lokusebenza, inombolo enkulu yezinzwa zokushisa nomswakama, izinzwa zokucindezela, izinzwa zokusheshisa, izilawuli kude, njll. zifakiwe. Lezi zimo zinezidingo eziphakeme zekhwalithi yesevisi yenethiwekhi kune-LPWAN (kuhlanganise I-NB-IoT, e-MTC, njll.), kodwa kungaphansi kwamandla e-URLLC kanye ne-eMB.

2. Inkambu yokugadwa kwamavidiyo: inkambu yamadolobha ahlakaniphile ihlanganisa ukuqoqwa kwedatha kanye nokucutshungulwa kwezimboni ezihlukahlukene zezicelo eziqondile ukuze kuqashwe ngempumelelo nokulawula izinsiza zasemadolobheni futhi kunikeze izinsiza ezihlukahlukene ezilula kubahlali basemadolobheni..

Ngokwesibonelo, ukuze kufakwe amakhamera evidiyo, izindleko zokusatshalaliswa kwezintambo ziya ngokuya zikhuphuka, kanye nokuguquguquka kokuthunyelwa okungenantambo kuya ngokuya kuduma. Kubandakanya izimo ezahlukahlukene ezifana nethrafikhi yasemadolobheni, ezokuphepha zasemadolobheni, kanye nokuphathwa kwedolobha, kanye nezimboni ezihlakaniphile, ukuphepha ekhaya, Izimo zesicelo ezifana nemvelo yehhovisi.

3. Inkambu yemishini egqokekayo: Ngokukhula kancane kancane kokunaka kwabantu empilweni jikelele, amawashi ahlakaniphile, namasongo ahlakaniphile, imishini yokuqapha izifo ezingapheli, imishini yokuqapha yezokwelapha, njll. bathole ukuduma ngezinga elikhulu. Enqubweni ephindaphindayo yemikhiqizo enjalo, amandla okuxhumana enethiwekhi aqinile, ukusetshenziswa kwamandla okuphansi, usayizi wedivayisi omncane, kanye nemisebenzi yesofthiwe enothile idingeka ngokushesha. Ngemuva kokuthi i-LTE Cat.1 ithathe indawo yenethiwekhi ye-2G, ikhulisa kancane kancane izimo zohlelo lokusebenza, futhi futhi ibeka isisekelo esihle se-5G RedCap emkhakheni ogqokekayo.

Izidingo eziyisisekelo zezimo zohlelo lokusebenza lwe-RedCap

Ubunkimbinkimbi bedivayisi: Isisusa esiyinhloko sohlobo olusha lwedivayisi ukunciphisa izindleko zedivayisi nokuba yinkimbinkimbi uma kuqhathaniswa ne-Rel-15/Rel-16 esezingeni eliphezulu eMBB kanye Amadivayisi we-URLLC. Lokhu kuyiqiniso ikakhulukazi ezinzwa zezimboni.

Usayizi wedivayisi: Imfuneko yezimo eziningi zokusetshenziswa ukuthi izinga livumela imiklamo yedivayisi enezici zefomu elihlangene.

Uhlelo lokuphakelwa: Uhlelo kufanele lusekele wonke amabhendi efrikhwensi angu-FR1/FR2 we-FDD ne-TDD.

Izidingo ezikhethekile zezimo zohlelo lokusebenza lwe-RedCap

1. Inkambu yenzwa yezimboni

Ku-3GPP TR 22.832 kanye ne-TS 22.104 izindinganiso, izidingo zesimo sohlelo lokusebenza zezinzwa zezimboni zichazwe: ikhwalithi yesevisi ye-QoS yokuxhumana okungenantambo ifinyelela 99.99%, futhi ukubambezeleka kokuphela ukuya ekupheleni kuncane kuno 100 ama-millisecond.

Kuzo zonke izimo zohlelo lokusebenza, izinga lokuxhumana lingaphansi kuka-2Mbps, ezinye ziyi-symmetrical uplink kanye ne-downlink, ezinye zidinga inani elikhulu lethrafikhi ye-uplink, amanye amadivaysi awukufakwa okuhleliwe, kanti amanye asebenza ngamabhethri iminyaka eminingana. Kwezinye izinhlelo zokusebenza zenzwa ezidinga isilawuli kude, ukubambezeleka kuphansi kakhulu, ukufinyelela 5-10 ama-millisecond (TR 22.804).

2. Inkambu yokugada amavidiyo

Ku-3GPP TR 22.804 ejwayelekile, isilinganiso esincane sokudluliswa kwamavidiyo amaningi ngu-2M~4Mbps, ukubambezeleka kukhulu kune 500 ama-millisecond, futhi ukwethembeka kufinyelela ku-99%~99.9%. Okunye ukuhanjiswa kwevidiyo enencazelo ephezulu kudinga u-7.5M~25Mbps, kanye nezimo ezinjalo zohlelo lokusebenza ikakhulukazi zinezidingo eziphakeme zokudluliswa kwe-uplink.

3. Inkambu yemishini egqokekayo

Izinga lokudluliswa kwedatha lamadivayisi agqokekayo ahlakaniphile ngokuvamile liphakathi kuka-5M~50Mbps ne-downlink no-2M~5Mbps uplink. Kwezinye izimo, izinga eliphakeme kakhulu, kufika ku-150Mbps downlink kanye ne-50Mbps uplink. Futhi ibhethri yocingo kufanele ihlale izinsuku ezimbalwa (ubuningi 1 ~ 2 amasonto).
