Techniques for long term evolution licensed assisted-access(LTE LAA) coexistence with other radio access technologies

Abstract:

Apparatus and methods for long term evolution (LTE) licensed-assisted access (LAA) communications at a user equipment (UE) are described herein. In an aspect, an example method includes a user equipment (UE) receiving a radio resource control (RRC) message from an eNB and searching for a discovery reference signal (DRS) associated with a secondary cell (Scell) of the eNB based at least on the information received in the RRC message. The example method further includes transmitting on the channel detected during the search.
