Abstract:

Proportional fair (PF) scheduling provides efficient allocation of resource while it results in relatively high head-of-line delay for some users in heavily loaded network. In contrast, first-in-first-out (FIFO) scheduling guarantees minimum delay for all users whereas the resource is inefficiently allocated. In this paper, a new hybrid scheduling algorithm with reduced feedback, named Hybrid PF/FIFO (HPF), which can decrease the scheduling delay and maintain efficient resource allocation is proposed. HPF behaves like PF scheduling when one or more users send(s) feedback. If none of the users send CSI feedback the resources will be allocated to the user having the largest delay similar to FIFO. Simulation results demonstrate that the proposed algorithm can achieve higher sumrate while reducing scheduling delays. The implementation of HPF does not involve any hardware upgrading. © 2012 IEEE.
