Carrier Aggregation yog dab tsi?
Carrier Aggregation yog lub thev naus laus zis tseem ceeb hauv LTE-A thiab ib qho ntawm cov thev naus laus zis tseem ceeb ntawm 5G.Nws hais txog kev siv tshuab ntawm kev nce bandwidth los ntawm kev sib txuas ntau yam kev ywj pheej ntawm tus neeg nqa khoom kom nce cov ntaub ntawv tus nqi thiab muaj peev xwm.
Cov qeb tshwj xeeb yog raws li nram no:
Nruam cov cab kuj aggregation: ob peb tus neeg nqa khoom me me uas nyob ib sab tau koom ua ke rau hauv cov cab kuj loj dua.Yog hais tias ob lub cab kuj muaj tib lub zaus band thiab nyob ib sab ntawm ib leeg nrog cov spectrum tsis tu ncua, nws yog hu ua nruam cov cab kuj sib sau ua ke hauv cov zaus band.
Kev sib sau ua ke tsis tu ncua: discrete ntau tus neeg nqa khoom tau sib sau ua ke thiab siv los ua qhov dav dua.Yog hais tias lub zaus bands ntawm ob lub cab kuj zoo ib yam, tab sis lub spectrum tsis tas mus li thiab muaj qhov sib txawv nyob rau hauv nruab nrab, nws yog hu ua discontinuous carrier aggregation nyob rau hauv lub zaus band;Yog hais tias qhov zaus bands ntawm ob lub cab kuj sib txawv, nws yog hu ua inter-band carrier aggregation.
Peb cov khoomFDM-6680 modulesiv cov khoom siv sib xyaw ua ke (CA), uas tuaj yeem sib sau ua ke ob 20MHz bandwidth cov neeg nqa khoom ua ke kom ua tiav 40 MHz wireless cab kuj bandwidth, zoo txhim kho tus nqi sib txuas thiab downlink thiab txhim kho lub zog thiab ib puag ncig adaptability ntawm tag nrho cov wireless kis tau tus mob.Kev ua haujlwm tshwj xeeb yog raws li hauv qab no:
1.Nws tuaj yeem txhawb nqa tag nrho cov bandwidth loj dua, txhawb nqa 20MHz + 20MHz tus neeg nqa khoom sib sau ua ke, thiab cov ntaub ntawv xa mus siab tshaj li 100Mbps.
2.Nws tuaj yeem txhawb nqa kev sib sau ua ke txuas ntxiv thiab tsis txuas ntxiv cov cab kuj sib sau ua ke, uas hloov tau yooj yim dua.
3.Nws tuaj yeem txhawb nqa kev sib sau ua ke ntawm cov kab sib txawv thiab kho qhov bandwidth ntawm cov neeg nqa khoom sib sau ua ke raws li kev cuam tshuam ib puag ncig thiab muaj cov peev txheej spectrum, ua kom yooj yim rau kev hloov mus rau ntau qhov xwm txheej.
4.Retransmission tuaj yeem ua tau ntawm cov neeg nqa khoom sib txawv kom tsis txhob cuam tshuam cov ntaub ntawv tom qab ib tus neeg nqa khoom cuam tshuam nrog.
5.Nws tuaj yeem txhawb nqa zaus hopping ntawm cov neeg nqa khoom sib txawv thiab nrhiav cov neeg nqa khoom tsis muaj kev cuam tshuam zoo dua.
