[in]	h_xin_addr	pointer to the PDCCH input payload sequence, spanning multiple DCIs. Each DCI payload starts at CUPHY_PDCCH_MAX_DCI_PAYLOAD_BYTES byte offset.
[in]	h_xin_desc	descriptor for PDCCH input payload. Currently unused.
[in]	num_coresets	number of coresets to be processed
[in]	num_DCIs	cumulative number of DCIs over all num_coresets coresets
[in]	h_params	pointer to PdcchParams struct
[in]	h_dci_params	pointer to cuphyPdcchDciPrm_t struct
[in]	stream	CUDA stream (currently not used)
