Energy Efficient Barring Factor Enabled Extended Access Barring for IoT Devices in LTE-Advanced
Synchronized Random Access Channel (RACH) attempts by Internet of Things (IoT) devices could result in Radio Access Network (RAN) overload in LTE-A. 3GPP adopted Barring Bitmap Enabled-Extended Access Barring (EAB-BB) mechanism that announces the EAB information (i.e., a list of barred Access Classes) through a barring bitmap as the baseline solution to mitigate the RAN overload. EAB-BB was ana...
متن کاملExports and Productivity:
While the role of exports in promoting growth in general, and productivity in particular, has been investigated empirically using aggregate data for countries and industries for a long time, only recently have comprehensive longitudinal data at the firm level been used to look at the extent and causes of productivity differentials between exporters and their counterparts which sell on the domes...
متن کاملExports and Productivity
This chapter investigates whether the best firms become exporters or whether a firm becomes better as a result of being an exporter. The evidence reviewed suggests that productivity growth in exporting firms generally occurs before rather than after the firm starts to export. It concludes that policy intervention to encourage exports is often useful, in particular where firms don’t recognise th...
متن کاملFaulty Conclusions
A case-control comparison of immunologic and psychological parameters in the multiple chemical sensitivity syndrome. This letter is prompted by Rall's editorial on media and science in the January issue of EHP (102:10). Rall implies that bad reporting is being conducted concerning dioxin, CFCs, and asbestos. Rall concludes by assuming that he is correct in assigning a high level of risk to each...
