Advanced machine type communication design for shared radio frequency spectrum operation

摘要

Aspects of the present disclosure provide techniques utilizing shared radio frequency spectrum (SRFS) for certain devices, such as machine type communication(s) (MTC) user equipments (UEs) and evolved or enhanced MTC (eMTC) UEs. An exemplary method, performed, for example, by a base station (BS), includes performing a channel clear assessment (CCA) for at least a portion of the SRFS including one or more narrowband regions, and communicating with at least one MTC UE, after performing the CCA, on at least one of the narrowband regions. A second exemplary method, performed, for example, by a MTC UE, generally includes receiving, from a BS, an assignment of resources in a narrowband region of the SRFS band for the MTC UE to use for communicating with the BS, and communicating with the BS on the narrowband region without performing a CCA for the narrowband region. A third exemplary method, performed, for example, by a MTC UE, generally includes performing a CCA for a narrowband region of the SRFS band and communicating with a BS on the narrowband region.
