Downlink Resource Allocation in Long Term Evolution (LTE)
A scheduler is very imperative constituent in base station (BS) because it allocates the resource block (RB) to different consumers. The preeminent scheduler is a scheduler which can produce optimize throughput, low latency system and can produce best coverage gains. In order to improve a best scheduling, the scheduler must be conscious of the channel quality and also the scheduler should have acquaintance of the channel quality for each sub carrier and each user. This paper is more discussing on a model for downlink scheduling in long term evolution (LTE) system, which focus on both consumer situations and retransmissions with packet blending hybrid automatic repeat request (HARQ).
Keywords: Downlink, HARQ, LTE, MCS, OFDMA, Resource Allocation, Scheduling
