RFmxLTE_CfgDownlinkAutoChannelDetection
int32 __stdcall RFmxLTE_CfgDownlinkAutoChannelDetection (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 autoPDSCHChannelDetectionEnabled, int32 autoControlChannelPowerDetectionEnabled, int32 autoPCFICHCFIDetectionEnabled, int32 reserved);
Purpose
Configures whether the values of physical downlink shared channel (PDSCH) parameters, control channel signal powers, and physical control format indicator channel (PCFICH) CFI are configured by a user or auto-detected by the measurement. The measurement ignores this function, when you set the
RFMXLTE_ATTR_LINK_DIRECTION
attribute to RFMXLTE_VAL_LINK_DIRECTION_UPLINK.
Parameters
| Input | ||||||
| Name | Type | Description | ||||
| instrumentHandle | niRFmxInstrHandle | Specifies the instrument session. The RFmx obtains this parameter from the RFmxLTE_Initialize function. | ||||
| selectorString | char[] | Specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used. Example: "signal::sig1" You can use the RFmxLTE_BuildSignalString function to build the selector string. |
||||
| autoPDSCHChannelDetectionEnabled | int32 | Specifies whether the values of the
RFMXLTE_ATTR_PDSCH_RESOURCE_BLOCK_ALLOCATION attribute, the corresponding PDSCH CW0 Modulation Type attribute, and the PDSCH Power attribute are
auto-detected by the measurement or user-specified.
This parameter is not valid, when you set the RFMXLTE_ATTR_DOWNLINK_CHANNEL_CONFIGURATION_MODE attribute to RFMXLTE_VAL_DOWNLINK_CHANNEL_CONFIGURATION_MODE_TEST_MODEL.
|
||||
| autoControlChannelPowerDetectionEnabled | int32 | Specifies whether the value of PSS Power, SSS Power, PBCH Power, PDCCH Power, and PCFICH Power attributes are
auto-detected by the measurement or user-specified. Currently, auto-detectionPHICH Power attribute is not supported. This parameter is not valid, when you set the RFMXLTE_ATTR_DOWNLINK_CHANNEL_CONFIGURATION_MODE attribute to RFMXLTE_VAL_DOWNLINK_CHANNEL_CONFIGURATION_MODE_TEST_MODEL.
|
||||
| autoPCFICHCFIDetectionEnabled | int32 | Specifies whether the value of
RFMXLTE_ATTR_PCFICH_CFI attribute is auto-detected by the measurement or user-specified. This parameter is not valid, when you set the RFMXLTE_ATTR_DOWNLINK_CHANNEL_CONFIGURATION_MODE attribute to RFMXLTE_VAL_DOWNLINK_CHANNEL_CONFIGURATION_MODE_TEST_MODEL.
|
||||
| reserved | int32 | This parameter is not supported in this release and it is reserved for future enhancements.
|
||||
Return Value
| Name | Type | Description | ||||||||
| status | int32 | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an RFmx function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the RFmxLTE_GetError function. The general meaning of the status code is as follows:
