How scheduling happens in LTE?
In LTE, the scheduling of the data traffic is based on the shared-channel transmission and the channel-dependent resource allocation. The eNB allocates radio resources in units of resource blocks to UEs, and sends the scheduling information to each UE on PDCCH.
What is downlink scheduling in LTE?
The downlink physical resource is represented as a time-frequency resource grid consisting of multiple Resource Blocks (RB). A resource block is divided in multiple Resource Elements (RE). A scheduler is a key element in the BS and it assigns the time and frequency resources to different users in the cell.
What is LTE scheduling algorithm?
In LTE cellular network, there are three basic scheduling algorithms. These algorithms are compared in term of fairness and overall throughput. These schedulers are the basic Round Robin, the opportunistic Max Rate and the Proportional Fair. The Round Robin scheduler assigns the RBs in equal TTI and in ordered manner.
What is Mac scheduling?
Sitting just above the Physical layer, the MAC Scheduler assigns bandwidth resources to user equipment and is responsible for deciding on how uplink and downlink channels are used by the eNodeB and the UEs of a cell. It also enforces the necessary Quality of Service for UE connections.
