METHOD AND APPARATUS FOR TRANSMITTING LTE WAVEFORMS IN SHARED SPECTRUM BY CARRIER SENSING

摘要

A method of operating a long term evolution (LTE) communication system on a shared frequency spectrum is disclosed. A user equipment (UE) is initialized on an LTE frequency band. A base station (eNB) monitors the shared frequency spectrum to determine if it is BUSY. The eNB transmits to the UE on the shared frequency spectrum if it is not BUSY. The eNB waits for a first time if it is BUSY and directs the UE to vacate the shared frequency spectrum after the first time.

1. A method of operating a wireless communication system on a shared frequency spectrum, comprising:
initializing a user equipment (UE) on a primary serving cell (PCell) on a licensed frequency spectrum; configuring the UE to communicate with a secondary serving cell (SCell) operating on a carrier in the shared frequency spectrum; monitoring the shared frequency spectrum by a base station (eNB) to determine if it is BUSY; transmitting to the UE on the shared frequency spectrum if it is not BUSY; waiting for a first time period if it is BUSY; and directing the UE to vacate the carrier in the shared frequency spectrum if it is BUSY after the first time period.
