channelBWs-DL

Indicatesfor each subcarrier spacing the UE supported channel bandwidths.

Absence ofthe channelBWs-DL (without suffix) for aband or absence of specific scs-XXkHz entry for a supported subcarrier spacingmeans that the UE supports the channel bandwidths among [5, 10, 15, 20, 25, 30,40, 50, 60, 80, 100] and [50, 100, 200] that were defined in clause 5.3.5 of TS38.101-1 version 15.7.0 [2] and TS 38.101-2 version 15.7.0 [3] for the givenband or the specific SCS entry.

For FR1,the bits in channelBWs-DL (withoutsuffix) starting from the leading / leftmost bit indicate 5, 10, 15, 20, 25,30, 40, 50, 60 and 80MHz. For FR2, the bits in channelBWs-DL(without suffix) starting from the leading / leftmost bit indicate 50,100 and 200MHz. The third / rightmost bit (for 200MHz) shall be set to 1.

For FR1,the leading/leftmost bit in channelBWs-DL-v1590indicates 70MHz, the second leftmost bit indicates 45MHz, the third leftmostbit indicates 35MHz, the fourth leftmost bit indicates 100MHz and all theremaining bits in channelBWs-DL-v1590shall be set to 0. The fourth leftmost bit (for 100MHz) is not applicable forbands n41, n48, n77, n78, n79 and n90 as defined in TS 38.101-1 [2].

NOTE:    To determine whether the UE supports aspecific SCS for a given band, the network validates the supportedSubCarrierSpacingDL and the scs-60kHz.

Todetermine whether the UE supports a channel bandwidth of 90 MHz, the networkmay ignore this capability and validate instead the channelBW-90mhz, the supportedBandwidthCombinationSetand the supportedBandwidthCombinationSetIntraENDC.For serving cell(s) with other channel bandwidths the network validates the channelBWs-DL, the supportedBandwidthCombinationSet, the supportedBandwidthCombinationSetIntraENDC, the asymmetricBandwidthCombinationSet (for a bandsupporting asymmetric channel bandwidth as defined in clause 5.3.6 of TS38.101-1 [2]) and supportedBandwidthDL.

剩下那些特定band的100Mhz带宽读法，就得去看featureSet中的定义了，不难。
