Exploring LTE radio resource-scheduling algorithms supported in ns-3
One of the major challenges for LTE operators is the optimal allocation of a limited and costly operating spectrum (radio resources) to their users. Operators must configure radio resource schedulers on evolved NodeBs (eNBs, or cells) for allocating spectrum resources efficiently to their connected UEs. Let’s understand how ns-3 models the LTE operating spectrum in terms of time and frequency chunks (radio resources) to support a variety of radio resource schedulers’ implementation. In general, LTE networks can be deployed in Frequency Division Duplex (FDD) or Time Division Duplex (TDD) operating modes, but ns-3 supports only the LTE FDD operating mode for spectrum management. In LTE FDD mode, for uplink and downlink transmissions, separate bandwidth is allocated. Let’s discuss ns-3 LTE operating spectrum modeling details in the following section.
