With the wide range of applications it is expected to provide, machine-type communication (MTC) is becoming an integral part of long term evolution-advanced (LTE-A). Due to deployment conditions, many MTC devices may face poor signal conditions, resulting in low operating SNR. Coverage enhancement for MTC devices is a major challenge identified by 3GPP. In this letter, we have identified a new category...
LTE uses the SC-FDMA radio access technology for its uplink data traffic transmission from the User Equipment (UE) to eNodeB. To the best of our knowledge the uplink MAC scheduling decisions at the eNodeB that have been proposed so far for Small Cell network are mostly based on single parameters like channel awareness, buffer status, or minimal power transmission. In this paper, we propose a novel...
Machine Type Communication (MTC) is becoming an integral part of the Long Term Evolution — Advanced (LTE-A) cellular network. Challenges arise when some of the MTC devices, due to the nature of their applications, are deployed in low signal locations. As per 3GPP requirements, there is a need for additional coverage enhancement up to 20 dB in comparison with LTE category 1 UE for MTC devices. In the...
Cellular communication systems especially LTE mandates the use of a simple and effective downlink power control of signals for controlling randomly dispersed user's throughput, interference, connectivity link. Users at the cell edge experience low throughout due to packet retransmission, and packet drop scenario. Due to the above problems, the operator loses revenue from the cell edge users due to...
Medium Access Control (MAC) scheduler entity forms one of the most important parts of any high speed packet access system like HSDPA or LTE. To the best of our knowledge the LTE MAC schedulers that had been proposed so far constitute of sub-carrier resource scheduling mostly based on single criteria like user throughput, link conditions, buffer constraints or power requirement. The above LTE MAC scheduler...
