1. A system comprising:
at least one hardware processor; and
at least one non-transitory memory storing instructions, which, when executed by the at least one hardware processor, cause the system to:
initiate, by a base station, a downlink prescheduling session for multiple subscriber units connected to a fixed wireless access network;
determine, by the base station, that the fixed wireless access network is configured for semi persistent scheduling (SPS);
responsive to determining that the fixed wireless access network is configured for SPS,
reconfigure, by the base station, the fixed wireless access network to implement dynamic scheduling for downlink data of the multiple subscriber units;
begin transmitting, by the base station, the downlink data to the multiple subscriber units using dynamic scheduling;
determine, by the base station, presence of physical downlink shared channel (PDSCH) congestion in the fixed wireless access network; and
responsive to determining the presence of PDSCH congestion,
terminate, by the base station, dynamic scheduling for a first one or more subscriber units of the multiple subscriber units,
wherein the first one or more subscriber units is associated with a first subscription tier; and
continue, by the base station, dynamic scheduling for a second one or more subscriber units of the multiple subscriber units,
wherein the second one or more subscriber units is associated with a second subscription tier higher than the first subscription tier.
