5I-G Redcap ithobela imigaqo ye-FDA? Lithini igama elipheleleyo le-5G RedCap?

5Inethiwekhi ye-G iyafana ne-bandwidth ephezulu kunye ne-latency ephantsi, kwaye sele isetyenziswa ngokubanzi ngoku, kodwa i-bandwidth ephezulu yenethiwekhi ye-5G nayo izisa iingxaki, eziziitheminali ezintsonkothileyo kunye nezixhobo ezingenazingcingo, ukusetyenziswa kwamandla amakhulu, kunye neendleko eziphezulu zezixhobo , ke kwezinye iimeko ezingadingi bandwidth enkulu, inethiwekhi ekhoyo ye-5G ayilona khetho lungcono.

Kulo mongo, 5UG RedCap wazalwa. Igama elipheleleyo leRedCap kukuNcitshiswa kwesakhono, oko kuthetha ukuncitshiswa kwesakhono, oko kuthetha ukuba iteknoloji yokuxhasa izixhobo zenethiwekhi ezikhaphukhaphu.

uluhlu lwabavelisi be-redcap chipset

5I-G RedCap inezi mpawu zilandelayo:

Ii-eriyali zezixhobo zesikhululo zinezibuko ezimbalwa zokwamkela nokuhambisa

Ukuxhasa unxibelelwano olupheleleyo lwe-duplex kunye nesiqingatha se-duplex

Isixhobo sisebenzisa amandla amancinci

Umyalelo wokumodareyitha osezantsi

i-bandwidth ephezulu esezantsi

Ukuxhasa iimpawu zokonga amandla

Ezi mpawu zobugcisa zingentla kukwenza lula ukuntsonkotha kwezixhobo zenethiwekhi kunye nezixhobo zetheminali, ukunciphisa iindleko zizonke zezixhobo, kunye nokunciphisa ukusetyenziswa kwamandla.

Iimeko eziphambili ze-5G RedCap zibandakanya:

Kwintsimi yeenzwa zoshishino: idatha eqokelelwe ngu abenzi boluvo ayifuni i-bandwidth enkulu ukuhlangabezana nemfuno;

Indawo yokuhlola ividiyo: ilungele iimeko ezingadingi ividiyo ekumgangatho ophezulu kwaye ayifuni ukubambezeleka okuphezulu;

Kwintsimi yezixhobo zokunxiba: Iimfuno ze-bandwidth yokuhanjiswa kwenethiwekhi aziphezulu, kwaye uninzi lwezantya zingaphantsi kwe-50Mbps;

Isantya esisezantsi ukuya-phakathi I-Intanethi yezinto: I-bandwidth yayo kunye neemfuno zokulibaziseka aziphezulu, kodwa ifuna ukusetyenziswa kwamandla aphantsi, izixhobo ezilula, kunye nexabiso eliphantsi;

Ngoku, 5I-G Redcap iqalise uvavanyo lokuqala. Kulindeleke ukuba kugqitywe ukuqinisekiswa kobugcisa kunye nokuvuthwa kwezixhobo kwisiqingatha sesibini salo nyaka. Kuya kubakho ukusetyenziswa korhwebo oluncinci kunyaka ozayo kunye nokusasazwa okukhulu kunyaka olandelayo.

5G RedCap Wikipedia:
I-RedCap (UkuNcitshiswa kweSakhono, ukuncitshiswa kwesakhono) yitekhnoloji ye-5G echazwe ngumbutho wokulinganisa we-3GPP kwaye yeyomgangatho omtsha we-NR ukukhanya. (NR encinci).

Ukuzalwa kweRedCap

Ngeentsuku zokuqala ze5G, ingqwalasela ye-5G yayiyi-bandwidth enkulu kunye ne-latency ephantsi. Nangona kunjalo, uyilo lweetshiphusi zokuqala ze-5G kunye neetheminali zazintsonkothile kakhulu. Yayingelulo utyalo-mali kwi-R&D iphezulu kakhulu, kodwa ixabiso leetheminali zenze ukuba zingamkeleki kwiimeko ezininzi zokusasazwa.

Kwiimeko ezininzi zesicelo, iimfuno zesantya ziphakathi, iimfuno zokusebenza ziphakathi, iimfuno zokusetyenziswa kwamandla ziphakathi, kwaye iimfuno zeendleko ziphakathi. Indlela yokufezekisa ukulingana phakathi komsebenzi kunye neendleko zezi mfuno, kwaye inokuhlalisana kunye nokuthunyelwa kwenethiwekhi ye-5G? Phantsi kwesi sibheno, I-RedCap yabakho.

NgoJuni 2019, kwi-3GPP RAN #84 intlanganiso, I-RedCap yaboniswa okokuqala njenge-Rel-17 yeSifundo seNtu (iprojekthi yophando).

NgoMatshi 2021, 3I-GPP yamkele ngokusesikweni i NR RedCap umgangatho wetheminali (Into yomsebenzi) iprojekthi.

NgoJuni 2022, 3IGPP Rel-17 ikhenkcezisiwe, oku kuthetha ukuba inguqulo yokuqala ye-5G ye-RedCap esemgangathweni isekwe ngokusemthethweni.

Iimeko zokusetyenziswa kweRedCap

Phakathi kwemigangatho ye-5G esekiweyo, zijolise ikakhulu kwiintlobo ezintathu zeemeko zesicelo, oko kukuthi:

1: Ukwandiswa kweBroadband yeMobile (eMBB, Ukwandiswa kweBroadband yeMobile)

2: Unxibelelwano loNxibelelwano lomatshini omkhulu (mMTC, Unxibelelwano loNxibelelwano lomatshini omkhulu)

3: UNxibelelwano oluthembeke kakhulu kunye neLow Latency (URLLC, UNxibelelwano oluthembeke kakhulu kunye neLow Latency)

Enye inkalo yesicelo efanele ukuqwalaselwa ngokubanzi luNxibelelwano oluKhethekileyo lweXesha (TSC, Unxibelelwano Olubuthathaka Lwexesha).

Ngexesha lokuthunyelwa kweenethiwekhi ze-5G, ukuba eMBB, mMTC, URLLC, kunye ne-TSC zonke zixhaswa kuthungelwano olufanayo, iya kwanelisa iimeko ezahlukeneyo zokuthunyelwa kwesicelo soshishino lwe-IoT kangangoko kunokwenzeka.

Kwinguqulo ye-3GPP Rel-16, kwimiba yesicelo se-TSC, inkxaso kuthungelwano oluthatha ixesha (I-TSN, Ixesha elinovakalelo lweNethiwekhi) kwaye 5Inkqubo ye-G indibaniselwano iyaziswa:

1. Kwintsimi yeenzwa zoshishino: 5Uqhagamshelo lwe-G luye lwaba yinto evuselela amaza olutsha lwe-Intanethi yeshishini kunye nedijithali, enokuthi isebenzise inethiwekhi ngokulula, ukuphucula ukusebenza kakuhle kwemveliso, ukunciphisa iindleko zokugcina kunye nokuqinisekisa ukhuseleko lokusebenza. Kwiimeko ezinjalo zesicelo, inani elikhulu leenzwa zobushushu kunye nokufuma, abenzi boxinzelelo, abenzi boluvo bokukhawuleza, abalawuli abakude, njl. zibandakanyiwe. Ezi meko zineemfuno eziphezulu zomgangatho wenkonzo yenethiwekhi kune-LPWAN (kuquka I-NB-IoT, e-MTC, njl.), kodwa ngaphantsi kwamandla e-URLLC kunye ne-eMBB.

2. Intsimi yokucupha ividiyo: Intsimi yezixeko ezihlakaniphile iquka ukuqokelelwa kwedatha kunye nokusetyenzwa kwamashishini ahlukeneyo ezicelo ezithe nkqo ukuze kubekwe iliso ngempumelelo ngakumbi kunye nokulawula izixhobo zasedolophini kunye nokubonelela ngeenkonzo ezahlukeneyo ezifanelekileyo kubahlali basezidolophini..

Umzekelo, ukuthunyelwa kweekhamera zevidiyo, iindleko zokusasazwa kweengcingo ziya zinyuka ngokunyuka, kunye nokuguquguquka kokuthunyelwa kwe-wireless kuya kuthandwa ngakumbi. Ibandakanya iimeko ezahlukeneyo ezifana netrafikhi yasezidolophini, ukhuseleko ezidolophini, kunye nolawulo lwedolophu, ngokunjalo neefektri ezikrelekrele, ukhuseleko ekhaya, Iimeko zesicelo ezifana nokusingqongileyo kweofisi.

3. Intsimi yezixhobo ezinxitywayo: Ngokunyuka ngokuthe ngcembe ingqalelo yabantu kwimpilo jikelele, iiwotshi ezikrelekrele, izacholo ezikrelekrele, izixhobo esweni izifo ezingapheliyo, izixhobo esweni zonyango, njl. bazuze ukuthandwa okukhulu. Kwinkqubo ephindaphindiweyo yeemveliso ezinjalo, amandla oqhagamshelwano oluqinileyo lwenethiwekhi, ukusetyenziswa kwamandla aphantsi, ubungakanani besixhobo esincinci, kunye nemisebenzi yesoftware etyebileyo ifuneka ngokukhawuleza. Emva kokuba i-LTE Cat.1 ithathe indawo yenethiwekhi ye-2G, yandisa kancinane iimeko zesicelo, kwaye ikwabeka isiseko esihle se-5G RedCap kwindawo enxibekayo.

Iimfuno ezisisiseko zeemeko zesicelo seRedCap

Ukuntsokotha kwesixhobo: Eyona nto ekhuthazwayo yohlobo olutsha lwesixhobo kukunciphisa iindleko zesixhobo kunye nobunzima xa kuthelekiswa ne-Rel-15 / Rel-16 ephezulu ye-EMBB kunye Izixhobo ze-URLLC. Oku kuyinyani ngokukodwa kwi-industrial sensors.

Ubungakanani besixhobo: Imfuneko kwiimeko ezininzi zokusetyenziswa kukuba umgangatho uvumela uyilo lwesixhobo kunye nezinto ezihlangeneyo.

Iskimu sokusasaza: Inkqubo kufuneka ixhase zonke iibhendi ze-FR1/FR2 ze-FDD kunye ne-TDD.

Iimfuno ezikhethekileyo zeemeko zesicelo seRedCap

1. Indawo yesivamvo soshishino

Kwi-3GPP TR 22.832 kunye ne-TS 22.104 imigangatho, Iimfuno zemeko yokusetyenziswa kwezinzwa zoshishino zichaziwe: umgangatho wenkonzo we-QoS wonxibelelwano olungenazingcingo lufikelela 99.99%, kwaye ukulibaziseka kokuphela ukuya ekupheleni kungaphantsi 100 imizuzwana.

Kuzo zonke iimeko zesicelo, izinga lonxibelelwano lingaphantsi kwe-2Mbps, ezinye zi-symmetrical uplink kunye ne-downlink, ezinye zifuna isixa esikhulu se-uplink traffic, ezinye izixhobo lufakelo olusisigxina, kwaye ezinye zisebenza ngebhetri iminyaka eliqela. Kwezinye iinkqubo zoluvo ezifuna ulawulo olude, I-latency iphantsi, ukufikelela 5-10 imizuzwana (TR 22.804).

2. Indawo yokuhlola ividiyo

Kwi-3GPP TR 22.804 umgangatho, umlinganiselo omncinci wosasazo lwevidiyo yi-2M ~ 4Mbps, ulibaziseko lukhulu kuno 500 imizuzwana, kwaye ukuthembeka kufikelela kwi-99% ~ 99.9%. Ezinye ii-high-definition video transmissions zifuna i-7.5M ~ 25Mbps, kunye neemeko zesicelo ezinjalo ikakhulu zineemfuno eziphezulu zokuhanjiswa kwe-uplink.

3. Intsimi yezixhobo ezinxitywayo

Izinga lokudluliselwa kwedatha yezixhobo ezinxibekayo ezihlakaniphile ubukhulu becala phakathi kwe-5M ~ 50Mbps ye-downlink kunye ne-2M ~ 5Mbps uplink. Kwezinye iimeko, izinga eliphezulu liphezulu, ukuya kuthi ga kwi-150Mbps ye-downlink kunye ne-50Mbps uplink. Kwakhona ibhetri yesixhobo kufuneka ihlale iintsuku ezininzi (ubuninzi 1 ~ 2 iiveki).
