Feature for feature, the iPad mini mainly bests its rivals in the 7-inch tablet market, but it does so at a price that’s 65 percent higher than those competitors. The mini has a larger display than Amazon’s Kindle Fire HD and Google’s Nexus 7. Its screen measures 7.9 inches diagonally, while the Fire and Nexus … Read more
What is AMC & its Algorithm in LTE The effective Eb/No and hence the spectral efficiency depend on BLER. However there are QoS requirements which also have to be considered. Taking both into account leads to a target BLER. AMC is in use in order to tune BLER so that the target value is reached. … Read more

UL and DL cell based scheduler The scheduling is performed on cell basis. The two main functions are to decide which UE(s) shall be scheduled, the number of resources and the MCS to be applied. Furthermore the scheduler needs to be QoS aware. There is priority given to random access responses, control data, HARQ retransmissions. … Read more
Scheduler types in LTE A variety of scheduling strategies is available in LTE. The scheduling strategy is based on a certain metric. – Round-Robin. No quality indication is taken into consideration. The resources are mainly shared in an equal manner. – Max C/I. The UE with the best channel conditions gets the highest priority. The … Read more
Scheduling Principle,Frequency and time domain in LTE Deployment of shared channels offers the possibility for scheduling. In this way information on varying channel conditions can be exploited to increase the overall throughput. Fast scheduling in time (1 ms) and frequency domain reduces latency and improves peak rate. Adaptive Modulation and Coding leads to higher data … Read more
Hybrid ARQ (HARQ) in LTE Hybrid ARQ (HARQ) leads to higher efficiency in transmission and error correction. There is one HARQ entity per UE with 8 stop-and-wait processes for each HARQ entity. Both incremental redundancy and chase combining are supported. The number of HARQ retransmissions targeted by the HARQ protocol depends on the network configuration. … Read more
