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...
Apart from research being done on using SDN in wired networks, there have been attempts made to extend similar concepts in wireless domain as well, to improve network performance. There have been several architectural proposals put forward which includes concepts like reconfigurable data plane in base-stations e.g. OpenRadio to different Radio Access Technology (RAT). These ideas can be extended further...
In a user equipment (UE) which supports multiple radio access technologies (multi-RAT), the access technology dependent part i.e., access stratum (AS) draw significant amount of power either in active or idle state. Simultaneous switching ON all UE supported idle RAT-ASs to support multi-RAT mobility, apart from the active RAT-AS can drain battery fast. Even the periodic cell search done by idle RAT-AS...
