Physical Sidelink Control Channel (PSCCH)

This module maps the Physical Control Channel (PDCCH) payload onto the resource grid as per control resource set configurations. The demodulation reference signal (DMRS) for PDCCH is filled in resource grid to equalizing information at the receiver.[3GPPTS38211PSCCHRM]_

class toolkit5G.ResourceMapping.ResourceMappingPSCCH(Nrb)

Parameters:

Nrb (int) – Number of Physical Resource Blocks allocated for Physical Sidelink Control Channel

Input:

• symbNumber (int) – \(\in \{2,3, \dots ,14\}\).

• scramblingID (int) – Defines the scramblingID \(\in \{0,1, \dots ,65535\}\).

• slotNumber (int) – Defines the number of slot, used for DMRS generation \(\in \{0,1, \dots ,65535\}\).

Output:

[numPorts, 14, numResourceBlocks*12], np.complex32 – PSCCH and PSCCH-DMRS loaded Grid.

Raises:

• ValueError – [Error in resourceMappingPSCCH]: ‘Nrb’ must be an interger!

• ValueError – [Error in resourceMappingPSCCH]: ‘numSymbols’ must be an interger!

• ValueError – [Error in resourceMappingPSCCH]: ‘NsymbPerSlots’ must be an integer!

• ValueError – [Error in resourceMappingPSCCH]: ‘numBatches’ must be interger!
