Title:
TIMER CONFIGURATION FOR SECONDARY CELLS IN LTE/LTE-A NETWORKS USING UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2015/134161
Kind Code:
A8
Abstract:
Configuration of secondary cell timers is disclosed for long term evolution (LTE)/LTE- Advanced (LTE-A) having unlicensed spectrum. In order to save power at a user equipment (UE), secondary cells may be deactivated by configuring a secondary cell deactivation timer. Because of transmission uncertainties when operating in LTE/LTE-A systems having unlicensed spectrum, the deactivation timers for unlicensed spectrum may be provided in a clear channel assessment (CCA) -dependent configuration, a CCA-independent configuration, or an alternative threshold-driven configuration of both CCA-dependent and CCA-independent configurations.
