TIMER CONFIGURATION FOR SECONDARY CELLS IN LTE/LTE-A NETWORKS USING UNLICENSED SPECTRUM |
摘要 |
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. |

1. A method of wireless communication, comprising:
receiving configuration of a duration for a deactivation timer for a secondary cell associated with a user equipment (UE); detecting a channel reserving signal over the secondary cell from a serving base station; and initiating the deactivation timer in response to the channel reserving signal. |
