5Mālama ʻo G Redcap i nā lula FDA? ʻO wai ka inoa piha o 5G RedCap?

5Ua like ka pūnaewele G me ka bandwidth kiʻekiʻe a me ka latency haʻahaʻa, a ua hoʻohana nui ʻia i kēia manawa, akā ʻo ka bandwidth kiʻekiʻe o ka pūnaewele 5G e lawe mai i nā pilikia, ʻo ia nā ʻōkuhi paʻakikī a me nā mea uila, hoʻohana mana nui, a me nā kumukūʻai kiʻekiʻe , no laila i kekahi mau hiʻohiʻona e koi ʻole i ka bandwidth nui, ʻaʻole ʻo ka pūnaewele 5G i kēia manawa ke koho maikaʻi loa.

Ma kēia pōʻaiapili, 5Ua hānau ʻia ʻo G RedCap. ʻO ka inoa piha o RedCap ʻo Reduced Capability, ʻo ia hoʻi ka hiki ke hoʻemi ʻia, 'o ia ho'i he 'enehana no ke kāko'o 'ana i nā lako pūnaewele māmā.

papa inoa o nā mea hana chipset redcap

5Loaʻa iā G RedCap nā hiʻohiʻona:

ʻOi aku ka liʻiliʻi o nā antenna lako terminal i ka loaʻa a me ka lawe ʻana i nā awa

Kākoʻo i ka kamaʻilio piha-duplex a me ka hapalua-duplex

E emi ana ka mana o ka lako

ʻO ke kauoha modulation haʻahaʻa

haʻahaʻa loa bandwidth

Kākoʻo i nā hiʻohiʻona mālama ikehu

ʻO nā hiʻohiʻona ʻenehana ma luna nei e hoʻomaʻamaʻa i ka paʻakikī o nā lako pūnaewele a me nā mea hana terminal, e hoemi i ke kumukuai holookoa o na lako, a hoemi i ka ikehu.

Aia nā hiʻohiʻona nui o 5G RedCap:

Ma ke kahua o nā ʻenehana ʻenehana: ka ʻikepili i hōʻiliʻili ʻia e nā mea ʻike ʻaʻole makemake i kahi bandwidth nui e hoʻokō i ka koi;

Māhele nānā wikiō: kūpono no nā hiʻohiʻona ʻaʻole pono ke wikiō kiʻekiʻe a ʻaʻole koi i ka latency kiʻekiʻe;

Ma ke kahua o nā mea hiki ke komo: ʻaʻole kiʻekiʻe nā koi bandwidth no ka hoʻoili pūnaewele, a ʻo ka hapa nui o nā wikiwiki ma lalo o 50Mbps;

Haʻahaʻa haʻahaʻa i ka māmā māmā Pūnaewele o na mea: ʻAʻole kiʻekiʻe kona bandwidth a me nā koi lohi, akā pono ia i ka hoʻohana haʻahaʻa haʻahaʻa, mea maʻalahi, a me ke kumukuai haahaa;

I kēia manawa, 5Ua hoʻomaka ʻo G Redcap i ka hoʻāʻo mua. Manaʻo ʻia e hoʻopau i ka hōʻoia ʻenehana a me ka hoʻomaʻamaʻa ʻana o nā lako i ka hapa ʻelua o kēia makahiki. E hoʻohana ʻia ka hoʻohana pāʻoihana liʻiliʻi i ka makahiki aʻe a me ka hoʻolaha nui ʻana i ka makahiki ma hope.

5G RedCap Wikipedia:
RedCap (Hiki ke hoemiia, hiki ke emi) he ʻenehana 5G i wehewehe ʻia e ka hui standardization 3GPP a nona ka ʻenehana hou maʻamau NR kukui (NR liʻiliʻi).

ʻO ka hānau ʻana o RedCap

I nā lā mua o 5G, ʻO ka manaʻo nui o 5G ma luna o ka bandwidth nui a me ka latency haʻahaʻa. Eia naʻe, paʻakikī loa ka hoʻolālā ʻana o nā chips 5G mua a me nā hopena. ʻAʻole wale ka hoʻopukapuka kālā ma R&D kiʻekiʻe loa, akā, ʻaʻole i ʻae ʻia ke kumukūʻai o nā terminal no nā hiʻohiʻona hoʻonohonoho maoli.

No nā hiʻohiʻona noiʻi he nui, ʻo ke ʻano o nā koi wikiwiki, ʻo nā koi hana he ʻano waena, ʻo nā koi hoʻohana mana he waena, a ʻo nā kumu kūʻai he mea waena. Pehea e hoʻokō ai i kahi kaulike ma waena o ka hana a me ke kumukūʻai no kēia mau koi, a hiki ke noho pū me ka hoʻolaha pūnaewele 5G? Ma lalo o kēia hoʻopiʻi, Ua hoʻokumu ʻia ʻo RedCap.

I Iune 2019, ma ka 3GPP RAN #84 halawai, Ua hōʻike mua ʻia ʻo RedCap ma ke ʻano he Rel-17 Study Item (papahana noiʻi).

Ma Malaki 2021, 3Ua ʻae ʻo GPP i ka NR RedCap hoʻomākaʻikaʻi terminal (Mea Hana) papahana.

I Iune 2022, 3ʻO GPP Rel-17 ka hau, ʻo ia hoʻi, ua hoʻokumu ʻia ka mana mua o ka maʻamau 5G RedCap.

5g mau mea hana redcap ma Kina - 5Mālama ʻo G Redcap i nā lula FDA? ʻO wai ka inoa piha o 5G RedCap?

Nā hiʻohiʻona noiʻi o RedCap

Ma waena o nā kūlana 5G i hoʻokumu ʻia, ua kuhikuhi nui ʻia lākou i ʻekolu ʻano o nā hiʻohiʻona noi, ʻo ia hoʻi:

1: Hoʻonui ʻia ʻo Mobile Broadband (eMBB, Hoʻonui ʻia ʻo Mobile Broadband)

2: ʻAno Mīkini Nui Kūkākūkā (mMTC, ʻAno Mīkini Nui Kūkākūkā)

3: Hiki ke hilinaʻi nui a me ka haʻahaʻa haʻahaʻa (URLLC, Hiki ke hilinaʻi nui a me ka haʻahaʻa haʻahaʻa)

ʻO kahi papa noi ʻē aʻe i kūpono i ka nānā maʻamau ʻo Time Sensitive Communication (TSC, Kūkākūkā Manawa Manawa).

I ka wā o ka hoʻolaha ʻana o nā pūnaewele 5G, ina eMBB, mMTC, URLLC, a kākoʻo ʻia ʻo TSC ma ka pūnaewele like, e hoʻomāʻona i nā hiʻohiʻona hoʻolālā noiʻi ʻoihana IoT e like me ka hiki.

Ma ka mana 3GPP Rel-16, no nā hiʻohiʻona noiʻi o TSC, kākoʻo no ka pūnaewele pili manawa (TSN, ʻIkepili manawa) a 5Pūnaehana G hoʻokomo ʻia ka hoʻohui:

1. Ma ke kahua o nā ʻenehana ʻenehana: 5Ua lilo ka pilina G i mea hoʻoikaika no ka nalu hou o ka pūnaewele ʻenehana a me ka digitalization, hiki ke hoʻopololei i nā pūnaewele, hoʻomaikaʻi i ka pono hana, e ho'ēmi i nā kumukūʻai mālama a hōʻoia i ka palekana hana. Ma ia mau hiʻohiʻona noi, ka helu nui o ka wela a me ka haʻahaʻa, nā mea ʻike kaomi, nā mea ʻike wikiwiki, nā mea hoʻoponopono mamao, etc. ua komo. Loaʻa i kēia mau hiʻohiʻona nā koi ʻoi aku ka maikaʻi o ka lawelawe pūnaewele ma mua o LPWAN (komo NB-IoT, e-MTC, etc.), akā haʻahaʻa ma mua o ka hiki o URLLC a me eMBB.

2. Ke kahua o ka nānā wikiō: ʻO ke kula o nā kūlanakauhale akamai e uhi i ka hōʻiliʻili ʻikepili a me ka hoʻoili ʻana o nā ʻoihana noi kūhelu i mea e nānā pono ai a mālama pono i nā kumuwaiwai kūloko a hāʻawi i nā lawelawe kūpono no nā kamaʻāina o ke kūlanakauhale..

ʻo kahi laʻana, no ka hoʻolaha ʻana i nā pahu kiʻi wikiō, ke piʻi aʻe nei ke kumukūʻai o ka hoʻolaha ʻana i nā uea, a ʻo ka maʻalahi o ka hoʻolaha ʻana i ka uea ʻole e lilo i mea kaulana. Hoʻopili ia i nā hiʻohiʻona like ʻole e like me ke kaʻa ʻana o ke kūlanakauhale, palekana kūlanakauhale, a me ka hooponopono kulanakauhale, a me nā hale hana akamai, palekana home, Nā hiʻohiʻona noiʻi e like me ke kaiapuni o ke keʻena.

3. ʻO ke kahua o nā mea hiki ke komo: Me ka mahuahua iki o ka noonoo o kanaka i ke ola kino, wati akamai, nā kūpeʻe lima akamai, lako kiaʻi maʻi mau, mea mālama kino, etc. ua hoʻokō i ka hoʻolaha nui. I ka hana iterative o ia mau huahana, ʻoi aku ka ikaika o ka pili pūnaewele, haʻahaʻa hoʻohana mana, liʻiliʻi liʻiliʻi, a ʻoi aku ka maikaʻi o ka lako polokalamu pono e pono ai. Ma hope o ka LTE Cat.1 i ka hoʻololi ʻana i ka pūnaewele 2G, hoʻonui mālie i nā hiʻohiʻona noi, a kau pū i kahi kumu maikaʻi no 5G RedCap ma ke kahua hiki ke hoʻohana.

Nā koi kumu o nā hiʻohiʻona noi RedCap

Paʻakikī paʻakikī: ʻO ka manaʻo nui no ke ʻano mea hou e hōʻemi i ke kumukūʻai a me ka paʻakikī i ka hoʻohālikelike ʻia me Rel-15/Rel-16 kiʻekiʻe eMBB a Nā polokalamu URLLC. Heʻoiaʻiʻo kēia no nā meaʻikeʻoihana.

Ka nui o ka mea hana: ʻO kahi koi no ka hapa nui o nā hihia hoʻohana ʻia ʻo ia ka mea e hiki ai i ka maʻamau ke hoʻolālā i nā hāmeʻa me nā mea ʻano compact.

Papahana hoʻolālā: Pono ka ʻōnaehana e kākoʻo i nā kaha alapine FR1/FR2 o FDD a me TDD.

Nā koi kūikawā o nā hiʻohiʻona noi RedCap

1. kahua ʻike ʻenehana

Ma ka 3GPP TR 22.832 a me TS 22.104 nā kūlana, ua wehewehe ʻia nā koi hiʻohiʻona noiʻi o nā sensor ʻenehana: hiki i ka maikaʻi o ka lawelawe QoS o ke kamaʻilio uila 99.99%, a ʻo ka lohi hope-a-hope ʻoi aku ka liʻiliʻi ma mua o 100 milliseconds.

No nā hiʻohiʻona noi a pau, ʻoi aku ka liʻiliʻi o ka kamaʻilio ma mua o 2Mbps, ʻO kekahi, he ʻano like ka uplink a me ka downlink, koi kekahi i ka nui o ka uplink traffic, ʻO kekahi mau mea hana he mau hoʻonohonoho paʻa, a ʻo kekahi poʻe i hoʻohana ʻia i ka pākaukau no kekahi mau makahiki. No kekahi mau noi sensor e koi ana i ka mana mamao, ʻano haʻahaʻa ka latency, hiki ana 5-10 milliseconds (ʻO TR 22.804).

2. Māhele nānā wikiō

Ma ka 3GPP TR 22.804 maʻamau, ʻO ka lihi iki o ka nui o nā hoʻoili wikiō he 2M ~ 4Mbps, oi aku ka lohi mamua o 500 milliseconds, a hiki i ka hilinaʻi i 99% ~ 99.9%. Pono kekahi mau hoʻoili wikiō kiʻekiʻe i ka 7.5M~25Mbps, a ʻo ia mau hiʻohiʻona noiʻi ʻoi aku ka nui o nā koi no ka hoʻouna uplink.

3. ʻO ke kahua o nā mea hiki ke komo

ʻO ka nui o ka lawe ʻana i ka ʻikepili o nā mea hiki ke hoʻohana ʻia ma waena o 5M~50Mbps downlink a me 2M~5Mbps uplink.. I kekahi mau hiʻohiʻona, ʻoi aku ka kiʻekiʻe o ka peak rate, a hiki i 150Mbps downlink a me 50Mbps uplink. Pono nō hoʻi ka pākaukau no ka mea hana no kekahi mau lā (kiʻekiʻe 1 ~ 2 pule).
