5G Redcap imagwirizana ndi malamulo a FDA? Dzina lonse la 5G RedCap ndi chiyani?

5G network ndi yofanana ndi bandwidth yapamwamba komanso low latency, ndipo wakhala akugwiritsidwa ntchito kwambiri tsopano, koma bandwidth yapamwamba ya 5G network imabweretsanso mavuto, omwe ndi ma terminals ovuta komanso zida zopanda zingwe, kugwiritsa ntchito mphamvu kwakukulu, ndi kukwera mtengo kwa zida , kotero muzochitika zina zomwe sizifuna bandwidth yayikulu, maukonde omwe alipo a 5G si abwino kwambiri.

M'nkhani ino, 5G RedCap adabadwa. Dzina lonse la RedCap ndi Kuchepetsa Mphamvu, zomwe kwenikweni zikutanthauza kuchepetsedwa kuthekera, kutanthauza kuti ndi luso kuthandizira opepuka maukonde zida.

mndandanda wa opanga redcap chipset

5G RedCap ili ndi izi:

Tinyanga tazida zokwezera zimakhala ndi madoko ochepa olandila ndi otumizira

Thandizani kulumikizana kwathunthu kwa duplex ndi theka-duplex

Chipangizo chimadya mphamvu zochepa

M'munsi modulation dongosolo

otsika kwambiri bandwidth

Thandizani zopulumutsa mphamvu

Zomwe zili pamwambazi ndikuchepetsa zovuta za zida zamaneti ndi zida zama terminal, kuchepetsa mtengo wonse wa zida, ndi kuchepetsa kugwiritsa ntchito mphamvu.

Zochitika zazikulu za 5G RedCap zikuphatikiza:

M'munda wa masensa mafakitale: zomwe zasonkhanitsidwa ndi masensa sichifuna bandwidth yayikulu kuti ikwaniritse zofunikira;

Malo owonera makanema: zoyenera pazochitika zomwe sizifuna kanema wapamwamba kwambiri ndipo sizifuna latency yapamwamba;

M'munda wa zida zovala: Zofunikira za bandwidth zotumizira maukonde sizokwera, ndipo maulendo ambiri ali pansi pa 50Mbps;

Liwiro lotsika mpaka lapakati Intaneti ya Zinthu: Zofunikira zake za bandwidth ndi kuchedwa sizokwera, koma zimafuna kugwiritsira ntchito mphamvu zochepa, zida zosavuta, ndi mtengo wotsika;

Pakadali pano, 5G Redcap yayamba kuyesa koyambirira. Akuyembekezeka kumaliza kutsimikizira zaukadaulo ndi kukhwima kwa zida mu theka lachiwiri la chaka chino. Padzakhala ntchito zazing'ono zamalonda chaka chamawa ndi kutumizidwa kwakukulu chaka chotsatira.

5G RedCap Wikipedia:
RedCap (Kuchepetsa Mphamvu, kuthekera kochepa) ndi ukadaulo wa 5G wofotokozedwa ndi 3GPP standardization bungwe ndipo ndi waukadaulo watsopano wa NR kuwala (NR pa).

Kubadwa kwa RedCap

M'masiku oyambirira a 5G, Cholinga cha 5G chinali makamaka pa bandwidth yayikulu komanso low latency. Komabe, mapangidwe a tchipisi oyambirira a 5G ndi ma terminals anali ovuta kwambiri. Sikuti ndalama za R&D kwambiri, koma mtengo wa ma terminals udapangitsanso kuti izikhala zosavomerezeka pazinthu zambiri zotumizira.

Kwa zochitika zambiri zogwiritsira ntchito, zofunikira zothamanga ndi zapakati, ntchito zofunika ndi zapakatikati, zofunika kugwiritsa ntchito mphamvu ndi zapakatikati, ndipo mtengo wake ndi wapakatikati. Momwe mungakwaniritsire mgwirizano pakati pa magwiridwe antchito ndi mtengo pazofunikira izi, ndipo imatha kukhala limodzi ndi kutumizidwa kwa netiweki ya 5G? Pansi pa pempholi, RedCap idayamba kukhalapo.

Mu June 2019, pa 3GPP RAN #84 msonkhano, RedCap idawonetsedwa koyamba ngati Phunziro la Rel-17 (ntchito yofufuza).

Mu March 2021, 3GPP idavomereza mwalamulo NR RedCap Terminal standardization (Ntchito) polojekiti.

Mu June 2022, 3GPP Rel-17 yazizira, zomwe zikutanthauza kuti mtundu woyamba wa 5G RedCap muyezo wakhazikitsidwa mwalamulo.

5g zida za redcap ku china - 5G Redcap imagwirizana ndi malamulo a FDA? Dzina lonse la 5G RedCap ndi chiyani?

Zochitika zogwiritsira ntchito RedCap

Pakati pa miyezo yokhazikitsidwa ya 5G, iwo makamaka umalimbana mitundu itatu ya zochitika ntchito, ndiye:

1: Kupititsa patsogolo Mobile Broadband (eMBB, Kupititsa patsogolo Mobile Broadband)

2: Massive Machine Type Communication (mMTC, Massive Machine Type Communication)

3: Ultra-reliable ndi Low Latency Communications (URLLC, Ultra-reliable ndi Low Latency Communications)

Gawo lina logwiritsa ntchito lomwe likuyenera kuyang'aniridwa pafupipafupi ndi Kulankhulana Kwanthawi Zonse (Mtengo wa TSC, Kulankhulana Kwanthawi Zonse).

Pakutumizidwa kwa ma network a 5G, ngati eMB, mMTC, URLLC, ndi TSC onse amathandizidwa pamaneti amodzi, idzakwaniritsa zochitika zosiyanasiyana zogwiritsira ntchito makampani a IoT momwe zingathere.

Mu mtundu wa 3GPP Rel-16, kwa zochitika zogwiritsira ntchito TSC, kuthandizira pa intaneti yokhudzidwa ndi nthawi (Mtengo wa TSN, Network Sensitive Networking) ndi 5G ndondomeko kuphatikiza kumayambitsidwa:

1. M'munda wa masensa mafakitale: 5Kulumikizana kwa G kwakhala chothandizira pakukula kwatsopano kwa intaneti yamakampani ndi digito, zomwe zimatha kutumiza ma network mosavuta, kupititsa patsogolo kupanga bwino, kuchepetsa mtengo wokonza ndikuonetsetsa chitetezo cha ntchito. Muzochitika zoterezi, chiwerengero chachikulu cha kutentha ndi chinyezi masensa, mphamvu masensa, mathamangitsidwe masensa, olamulira akutali, ndi zina. zikuphatikizidwa. Zochitika izi zili ndi zofunikira zapamwamba pamtundu wa intaneti kuposa LPWAN (kuphatikizapo NB-IoT, e-MTC, ndi zina.), koma otsika kuposa kuthekera kwa URLLC ndi eMBB.

2. Gawo loyang'anira makanema: gawo la mizinda yanzeru limakhudza kusonkhanitsa deta ndikukonza mafakitale osiyanasiyana osunthika kuti athe kuyang'anira bwino komanso kuwongolera chuma chakumatauni ndikupereka ntchito zosiyanasiyana zosavuta kwa okhala m'matauni..

Mwachitsanzo, kuyika makamera avidiyo, mtengo wotumizira mawaya ukukulirakulira, ndi kusinthasintha kwa kutumizidwa opanda zingwe kukukhala kutchuka kwambiri. Zimakhudza zochitika zosiyanasiyana monga kuchuluka kwa magalimoto m'tauni, chitetezo mtawuni, ndi kasamalidwe ka mizinda, komanso mafakitale anzeru, chitetezo kunyumba, Zochitika zantchito monga malo akuofesi.

3. Munda wa zipangizo kuvala: Ndi kuwonjezereka kwapang'onopang'ono kwa chidwi cha anthu ku thanzi labwino, mawotchi anzeru, zibangili zanzeru, zida zowunikira matenda osatha, zida zowunikira zamankhwala, ndi zina. apeza kutchuka kwakukulu. Mu njira yobwerezabwereza ya zinthu zoterezi, mphamvu zolumikizirana ndi netiweki, kugwiritsa ntchito mphamvu zochepa, kachipangizo kakang'ono, ndi ntchito zolemera zamapulogalamu ndizofunikira mwachangu. LTE Cat.1 ikayamba kusintha netiweki ya 2G, imakulitsa pang'onopang'ono zochitika zogwiritsira ntchito, komanso imayala maziko abwino a 5G RedCap m'munda wovala.

Zofunikira zoyambira pazogwiritsa ntchito RedCap

Chipangizo chovuta: Cholinga chachikulu cha mtundu wa chipangizo chatsopano ndikuchepetsa mtengo wa chipangizo ndi zovuta poyerekeza ndi Rel-15 / Rel-16 yapamwamba-end eMBB ndi Zida za URLLC. Izi ndi zoona makamaka kwa mafakitale masensa.

Kukula kwa chipangizo: Chofunikira pazochitika zambiri zomwe zimagwiritsidwa ntchito ndikuti mulingo umathandizira kupanga zida zokhala ndi mawonekedwe ophatikizika.

Ndondomeko yotumizira: Dongosololi liyenera kuthandizira magulu onse amtundu wa FR1/FR2 a FDD ndi TDD.

Zofunikira zapadera pazogwiritsa ntchito RedCap

1. Industrial sensor field

Mu 3GPP TR 22.832 ndi TS 22.104 miyezo, Zofunikira pakugwiritsa ntchito ma sensor a mafakitale zikufotokozedwa: khalidwe lautumiki la QoS la kulumikizana opanda zingwe limafikira 99.99%, ndipo kuchedwa kwakumapeto ndi kocheperako 100 milliseconds.

Kwa zochitika zonse zogwiritsira ntchito, kuyankhulana ndi zosakwana 2Mbps, ena ndi ma symmetrical uplink ndi downlink, zina zimafuna kuchuluka kwa magalimoto a uplink, zida zina ndizokhazikika, ndipo ena amakhala ndi batire kwa zaka zingapo. Kwa mapulogalamu ena a sensor omwe amafunikira chiwongolero chakutali, latency ndi yochepa, kufikira 5-10 milliseconds (TR 22.804).

2. Malo owonera makanema

Mu 3GPP TR 22.804 muyezo, kutsika kwamavidiyo ambiri ndi 2M ~ 4Mbps, kuchedwa ndi kwakukulu kuposa 500 milliseconds, ndipo kudalirika kumafika 99% ~ 99.9%. Makanema ena odziwika bwino amafunikira 7.5M ~ 25Mbps, ndipo mawonekedwe oterowo amakhala ndi zofunikira zapamwamba pakufalitsa kwa uplink.

3. Munda wa zipangizo kuvala

Kutumiza kwa data kwa zida zovala zanzeru nthawi zambiri kumakhala pakati pa 5M ~ 50Mbps downlink ndi 2M~5Mbps uplink. Muzochitika zina, chiwongola dzanja ndichokwera, mpaka 150Mbps downlink ndi 50Mbps uplink. Komanso batire la chipangizocho liyenera kukhala kwa masiku angapo (pazipita masabata 1-2).
