class DownlinkCls

Downlink commands group definition. 1 total commands, 0 Subgroups, 1 group commands Repeated Capability: Stream, default value after init: Stream.S1

class DownlinkStruct

Response structure. Fields:

• Cluster: str: binary Bitmap, enabling or disabling the individual RBGs 1 means RBG is allocated, 0 means RBG is not allocated The number of bits depends on the cell bandwidth and equals the total number of RBGs. The bitmap starts with RBG 0 (most significant bit) and continues with increasing RBG index / frequency. Example for BW 20 MHz: #B1010100000000000000000011 allocates RBG 0, 2, 4, 23, 24

• Modulation: enums.Modulation: QPSK | Q16 | Q64 | Q256 | Q1024 QPSK | 16-QAM | 64-QAM | 256-QAM | 1024-QAM

• Trans_Block_Size_Idx: int: numeric Transport block size index

get(secondaryCompCarrier=SecondaryCompCarrier.Default, stream=Stream.Default) → DownlinkStruct

# SCPI: CONFigure:LTE:SIGNaling<instance>:CONNection:SCC<Carrier>:UDCHannels:LAA:FBURst:FSUBframes:MCLuster:DL<Stream>
value: DownlinkStruct = driver.configure.connection.scc.udChannels.laa.fburst.fullSubFrames.mcluster.downlink.get(secondaryCompCarrier = repcap.SecondaryCompCarrier.Default, stream = repcap.Stream.Default)

Configures a user-defined downlink channel with multi-cluster allocation, for LAA, fixed bursts. The <Cluster> setting applies to all subframes of the burst and to all DL streams. The other settings apply to subframes with full allocation and DL stream <s>. The allowed input ranges have dependencies and are described in the background information, see ‘User-defined channels for LAA’ and especially Table ‘RBG parameters’.

param secondaryCompCarrier:

optional repeated capability selector. Default value: CC1 (settable in the interface ‘Scc’)

param stream:

optional repeated capability selector. Default value: S1 (settable in the interface ‘Downlink’)

return:

structure: for return value, see the help for DownlinkStruct structure arguments.
