/*
* NR SLOT PROCESSING SEQUENCE
*
* Processing occurs with following steps for connected mode:
*
* - Rx samples for a slot are received,
* - PDCCH processing (including DCI extraction for downlink and uplink),
* - PDSCH processing (including transport blocks decoding),
* - PUCCH/PUSCH (transmission of acknowledgements, CSI, ... or data).
*
* Time between reception of the slot and related transmission depends on UE processing performance.
* It is defined by the value NR_UE_CAPABILITY_SLOT_RX_TO_TX.
*
* In NR, network gives the duration between Rx slot and Tx slot in the DCI:
* - for reception of a PDSCH and its associated acknowledgment slot (with a PUCCH or a PUSCH),
* - for reception of an uplink grant and its associated PUSCH slot.
*
* So duration between reception and it associated transmission depends on its transmission slot given in the DCI.
* NR_UE_CAPABILITY_SLOT_RX_TO_TX means the minimum duration but higher duration can be given by the network because UE can support it.
*
* Slot k

*
* Remark: processing is done slot by slot, it can be distribute on different threads which are executed in parallel.
* This is an architecture optimization in order to cope with real time constraints.
* By example, for LTE, subframe processing is spread over 4 different threads.
