This chapter discusses the key radio-resource-management functionality relevant for LTE, including downlink and uplink scheduling and reporting of channel-state information.
scheduling; channel-state information (CSI)
The scheduler is a key element and to a large degree determines the overall behavior of the system. Both uplink and downlink transmissions are scheduled and, consequently, there is a downlink and an uplink scheduler in the eNodeB.
The downlink scheduler is responsible for dynamically controlling the terminal(s) to transmit to. Each of the scheduled terminals is provided with a scheduling assignment consisting of the set of resource blocks upon which the terminal’s DL-SCH
