Advanced machine type communication design for shared radio frequency spectrum operation

摘要

Aspects of the present disclosure provide for a shared radio frequency spectrum (one or more) for certain devices, such as machine type communication (MTC) user equipment (UE) and evolved or enhanced MTC (eMTC) UE ( Techniques utilizing SRFS) are provided. For example, an exemplary method performed by a base station (BS) includes performing channel clear assessment (CCA) on at least a portion of SRFS that includes one or more narrowband regions, and these narrowbands. Communicating with at least one MTC UE after performing CCA in at least one of the regions. For example, a second exemplary method performed by an MTC UE generally receives from the BS an allocation of resources in a narrow band region of the SRFS band for use by the MTC UE to communicate with the BS. And communicating with the BS in this narrowband region without performing CCA on this narrowband region.
