LTE/LTE-A 2 TIMER CONFIGURATION FOR SECONDARY CELLS IN LTE/LTE-A NETWORKS USING UNLICENSED SPECTRUM

摘要

The configuration of secondary cell timers for Long Term Evolution (LTE) / LTE-Advanced (LTE-A) with unlicensed spectrum is disclosed. To save power at the user equipment (UE), the secondary cells may be deactivated by configuring a secondary cell deactivation timer. Due to the transmission uncertainties when operating in LTE / LTE-A systems with unlicensed spectrum, deactivated tamers for unlicensed spectrum can be classified into a clear channel assessment (CCA) -dependent configuration, a CCA- Alternatively, alternatives to both CCA-dependent and CCA-independent configurations may be provided in a small threshold-driven configuration.
