LIE addresses the escalating demand of data rates by introducing several multiple-input and multiple-output (MIMO) transmission modes. One of the potential MIMO technique is to send independent data streams over multiple antennas. This is known as spatial multiplexing. The simplest form of spatial multiplexing is open-loop spatial multiplexing (OLSM). The performance of OLSM can be improved further...
In LTE, resource scheduling algorithm is one of the key parameters that determine the overall system and UE performances in terms of throughput and fairness respectively. Multiple scheduling techniques are available that emphasizes on optimizing any one of the key system performance parameters. Among them the most potential algorithms are proportional fair (PF) and round robin (RR). PF optimizes UE...
LTE-A addresses the challenges of coverage block holes and increase in user density with new features, such as small cell and femto cell. Small cell can be an inexpensive substitute to macro cell in coverage depleted areas. In contrast, heterogeneous network using femto cells with its ubiquitous coverage, can deliver high-speed data. Resource scheduling algorithm has an important role in determining...
