1. A network node for communicating with user equipments (UEs) in a wireless communication system, the network node comprising:
a transmitter configured to transmit data to the UEs; and
processor circuitry configured to:
perform a network slice quota (NSQ) management function, the NSQ management function including:
counting a number of the UEs operating in a network slice;
counting a number of protocol data unit (PDU) sessions operating in the network slice; and
adjusting a data rate limit of at least one of the UEs operating in the network slice based on an aggregate maximum bit rate (AMBR) for the network slice reaching or exceeding a predetermined data rate limitation of the network slice, the AMBR for the network slice being an aggregate of respective bit rates for each PDU session included in the number of PDU sessions, the adjusting being made in blocks of predetermined quantized bit rates (QBRs), and wherein the adjusting further includes adding an additional UE to a set of UEs operating in the network slice using a reserve bit rate without changing bit rates of the set of UEs operating in the network slice; and
cause to control the transmitter to transmit the data to the at least one of the UEs based on the adjusted data rate limit.
