virtual bool	channelIsUsable (int subChannel, int timeSlot, RequestForResource &request, SchedulerStatePtr schedulerState, SchedulingMapPtr schedulingMap) const
	true if requested PDU can be scheduled on that resource block

	DSAStrategy (const wns::pyconfig::View &config)
virtual simTimeType	getCompoundDuration (RequestForResource &request) const
	if phyModePtr is specified, the duration of the PDU on the subChannel can be calculated. Otherwise, undefined means: assume the highest PhyMode
int	getSpatialLayerForSubChannel (int subChannel, int timeSlot, RequestForResource &request, SchedulerStatePtr schedulerState, SchedulingMapPtr schedulingMap) const
	true if requested PDU can be scheduled on that subChannel
virtual void	initialize (SchedulerStatePtr schedulerState, SchedulingMapPtr schedulingMap)
	call this before each timeSlot/frame. Important to reset starting values.
virtual void	setColleagues (RegistryProxyInterface *_registry)
	called once at the beginning
virtual	~DSAStrategy ()
Protected Attributes
bool	adjacentSubchannelsOnUplink
	UL: true if all subchannels must be adjacent (SC-FDMA).

double	highestDataRatePerSubChannel
	data rate per subChannel assuming the highest PhyMode

	myUserID is important in channelIsUsable()
bool	oneUserOnOneSubChannel
	may different users share a sbubchannel? Usually not.
