5G Redcap inoenderana nemirairo yeFDA? Nderipi zita rakazara re5G RedCap?

5G network yakafanana neyepamusoro bandwidth uye yakaderera latency, uye yave kushandiswa zvakafara zvino, asi iyo yakakwirira bandwidth ye5G network inounzawo matambudziko, ayo ari materminals akaoma uye michina isina waya, kushandiswa kwesimba kukuru, uye yakakwirira midziyo mari , saka mune mamwe mamiriro asingade hombe bandwidth, iyo iripo 5G network haisi iyo yakanakisa sarudzo.

Muchirevo chechinyorwa ichi, 5G RedCap akazvarwa. Zita rakazara reRedCap rakaderedzwa Kugona, izvo chaizvoizvo zvinoreva kuderedzwa kugona, zvinoreva kuti inyanzvi yekutsigira lightweight network michina.

redcap chipset vagadziri runyorwa

5G RedCap ine zvinotevera maitiro:

Terminal zvishandiso antennas ane mashoma ekugamuchira uye ekufambisa madoko

Tsigira yakazara-duplex uye hafu-duplex kutaurirana

Mudziyo unopedza simba shoma

Lower modulation order

yakaderera yepamusoro bandwidth

Tsigira maitiro ekuchengetedza simba

Iwo ari pamusoro apa tekinoroji maficha ndeekurerutsa kuomarara kwetiweki zvishandiso uye terminal michina, kuderedza mari yose yemidziyo, uye kuderedza kushandiswa kwesimba.

Iwo makuru mamiriro e5G RedCap anosanganisira:

Mumunda wemaindasitiri sensors: iyo data yakaunganidzwa na sensors haidi bandwidth yakakura kuti isangane nezvinodiwa;

Vhidhiyo yekutarisa nzvimbo: akakodzera mamiriro asingade vhidhiyo yemhando yepamusoro uye isingade yakakwira latency;

Mumunda wezvigadzirwa zvinopfekwa: iyo bandwidth inodiwa yekutapurirana network haina kukwirira, uye akawanda ekumhanya ari pasi pe50Mbps;

Kumhanya kwakaderera-kusvika-pakati Internet yezvinhu: Yayo bandwidth uye kunonoka zvinodiwa hazvina kukwirira, asi zvinoda kushandiswa kwesimba shoma, midziyo iri nyore, uye mutengo wakaderera;

Parizvino, 5G Redcap yatanga kuyedzwa kwekutanga. Inotarisirwa kupedzisa kusimbiswa kwehunyanzvi uye kukura kwemidziyo muhafu yechipiri yegore rino. Pachave nediki-zviyero zvekutengeserana kushandiswa gore rinouya uye hukuru-hukuru kuendesa gore rinotevera.

5G RedCap Wikipedia:
RedCap (Yakaderedzwa Kugona, kuderedzwa kugona) tekinoroji ye5G inotsanangurwa ne3GPP yekumisikidza sangano uye ndeye tekinoroji nyowani chiyero cheNR mwenje. (NR zvishoma).

Kuberekwa kweRedCap

Mumazuva ekutanga e5G, kutarisisa kwe5G kwaive kwakanyanya pane yakakura bandwidth uye yakaderera latency. Zvisinei, dhizaini yekutanga 5G machipisi uye materminal aive akaomarara zvakanyanya. Kwete chete yaive mari muR&D yakakwirira kwazvo, asi mutengo wematerminals wakaitawo kuti usagamuchirwe kune akawanda chaiwo chaiwo ekutumira mamiriro.

Kune akawanda maficha ekushandisa, zvinodikanwa zvekumhanya zviri pakati nepakati, zvinodiwa kuita zviri pakati nepakati, simba rekushandisa zvinodiwa zviri pakati nepakati, uye zvinodiwa mari zviri pakati nepakati. Maitiro ekuwana chiyero pakati pekuita uye mutengo wezvinodikanwa izvi, uye inogona kugarisana ne5G network deployment? Pasi pechikumbiro ichi, RedCap yakatanga.

Muna Chikumi 2019, pa 3GPP RAN #84 musangano, RedCap yakatanga kuratidzwa seRel-17 Chidzidzo Chinhu (tsvakurudzo chirongwa).

Muna March 2021, 3GPP yakabvumira zviri pamutemo NR RedCap terminal standardization (Basa Item) project.

Muna Chikumi 2022, 3GPP Rel-17 yakaomeswa nechando, zvinoreva kuti yekutanga vhezheni ye5G RedCap standard inogadzwa zviri pamutemo.

Mamiriro ekushandisa eRedCap

Pakati pezvakagadziriswa 5G zviyero, ivo vanonyanya kunangwa pamhando nhatu dzemashandisirwo emamiriro ezvinhu, kureva:

1: Yakavandudzwa Mobile Broadband (eMBB, Yakavandudzwa Mobile Broadband)

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

3: Ultra-yakavimbika uye yakaderera Latency Kukurukurirana (URLLC, Ultra-yakavimbika uye yakaderera Latency Kukurukurirana)

Imwe nzvimbo yekushandisa inokodzera kutariswa zvakanyanya ndeyeNguva Inonzwa Kukurukurirana (TSC, Kukurukurirana Inobata Nguva).

Panguva yekutumirwa kwe5G network, kana eMBB, mMTC, URLLC, uye TSC ese anotsigirwa mune imwechete network, iyo inogutsa akasiyana-siyana eIoT indasitiri application deployment scenarios zvakanyanya sezvinobvira.

Muiyo 3GPP Rel-16 vhezheni, yemamiriro ekushandisa eTSC, rutsigiro rwetiweki inobata nguva (TSN, Time Sensitive Networking) uye 5G system kubatanidzwa kunosumwa:

1. Mumunda wemaindasitiri sensors: 5G kubatana kwave kukonzeresa kune itsva wave yeindasitiri yeInternet uye digitalization, iyo inogona flexible deploy network, kunatsiridza kugadzirwa kwakanaka, kuderedza mari yekuchengetedza uye kuve nechokwadi chekuchengetedzwa kwekushanda. Mune mamiriro ekushandisa akadaro, nhamba huru yekushisa uye humidity sensors, pressure sensors, acceleration sensors, remote controller, etc. zvinosanganisirwa. Aya mamiriro ane zvakakwirira zvinodikanwa zvetiweki sevhisi mhando kupfuura LPWAN (kusanganisira NB-IoT, e-MTC, etc.), asi yakaderera pane kugona kwe URLLC uye eMBB.

2. Munda wekutarisa vhidhiyo: iyo munda wemaguta akangwara inovhara kuunganidzwa kwedata uye kugadzirisa akasiyana vertical application maindasitiri kuitira kunyatso tarisa uye kutonga zviwanikwa zvemudhorobha uye nekupa akasiyana masevhisi ari nyore kune vagari vemudhorobha..

Semuyenzaniso, yekuendesa mavhidhiyo kamera, mutengo wekutumirwa kwewaya urikukwira nekukwira, uye kuchinjika kwewireless deployment iri kuramba ichizivikanwa. Inosanganisira akasiyana mamiriro senge traffic yemudhorobha, kuchengetedzwa kwemaguta, uye manejimendi emaguta, pamwe chete nemafekitari akangwara, kuchengetedzwa kwemusha, Mamiriro ekushandisa akadai senzvimbo yehofisi.

3. Munda wezvishandiso zvinopfekwa: Nekuwedzera zvishoma nezvishoma kwekutarisisa kwevanhu kune hutano hwese, smart wachi, smart bracelets, midziyo yekuongorora zvirwere zvisingaperi, midziyo yekuongorora mishonga, etc. vakawana mukurumbira mukuru. Mukuita kwekudzokorora kwezvigadzirwa zvakadaro, yakasimba network yekubatanidza kugona, kushandiswa kwesimba kwakaderera, diki mudziyo saizi, uye akapfuma software mabasa anodiwa nekukurumidza. Mushure meLTE Cat.1 inotora 2G network kutsiva, inowedzera zvishoma nezvishoma mamiriro ekushandisa, uye zvakare inoisa hwaro hwakanaka hwe5G RedCap mumunda unopfekwa.

Zvinodiwa zvekutanga zveRedCap application scenarios

Chigadzirwa chakaoma: Iyo huru yekurudziro yemhando nyowani yemudziyo kudzikisa mutengo wemudziyo uye kuomarara kana ichienzaniswa neRel-15/Rel-16 yakakwirira-yekupedzisira eMBB uye URLLC zvishandiso. Izvi ndezvechokwadi kunyanya kune maindasitiri sensors.

Saizi yemudziyo: Chinodiwa pamakesi mazhinji ekushandisa ndechekuti chiyero chinogonesa dhizaini yedhizaini ine compact fomu zvinhu.

Deployment scheme: Iyo sisitimu inofanirwa kutsigira ese FR1/FR2 frequency mabhendi eFDD uye TDD.

Zvinodiwa zvakakosha zveRedCap application scenarios

1. Industrial sensor field

Mune 3GPP TR 22.832 uye TS 22.104 mipimo, iyo mamiriro ekushandisa zvinodiwa zvemaindasitiri sensors anotsanangurwa: iyo QoS sevhisi yemhando yekutaurirana isina waya inosvika 99.99%, uye kunonoka-ku-kuguma kunonoka kuduku pane 100 milliseconds.

Kune ese maficha ekushandisa, chiyero chekukurukurirana chiri pasi pe2Mbps, mamwe ari symmetrical uplink uye downlink, zvimwe zvinoda huwandu hukuru hweuplink traffic, mamwe madivayiri akaiswa zvigadziriso, uye mamwe anofambiswa nebhatiri kwemakore akati wandei. Kune mamwe masensor application anoda kure kure, iyo latency yakaderera, kusvika 5-10 milliseconds (TR 22.804).

2. Vhidhiyo yekutarisa nzvimbo

Mune 3GPP TR 22.804 standard, iyo bhiti mwero yeakawanda vhidhiyo kutapurirana i2M ~ 4Mbps, kunonoka kunopfuura 500 milliseconds, uye kuvimbika kunosvika 99% ~ 99.9%. Mamwe epamusoro-tsanangudzo mavhidhiyo ekufambisa anoda 7.5M ~ 25Mbps, uye mamiriro ekushandisa akadaro anonyanya kuve nepamusoro zvinodiwa zvekufambiswa kweuplink.

3. Munda wezvishandiso zvinopfekwa

Huwandu hwekutumira data hwemidziyo inopfekeka yakangwara iri pakati pe5M~50Mbps downlink uye 2M~5Mbps uplink.. Mune zvimwe zviitiko, mwero wepamusoro wakakwira, kusvika ku150Mbps downlink uye 50Mbps uplink. Zvakare bhatiri remudziyo rinofanira kugara kwemazuva akati wandei (yakawanda 1 ~ 2 mavhiki).
