Abstract: Certain aspects of the present disclosure generally relate to wireless communications, and more specifically increasing user capacity through a frame structure which supports enhanced Machine Type Communication (eMTC) UL multi-user multiplexing. For example, a User Equipment (UE) identifies at least one narrowband region within a wider system bandwidth. The UE receives signaling, from a base station, indicating a sub-region of the narrowband region assigned to the UE for transmitting symbols of a physical uplink channel that are multiplexed with symbols transmitted by one or more other UEs in the narrowband region. The UE transmits the physical uplink channel in the assigned sub-region. Similar techniques are also provided that may be applied to DL multi-user multiplexing.

Abstract: 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.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for mitigating resource conflicts between ultra low latency (ULL) and legacy transmissions. A base station may determine a region of a subframe having overlapping resource allocations for a first device of a first type (e.g., ULL device) and a second device of a second type (e.g., legacy device), wherein the first device of the first type has a capability to perform certain procedures with low latency relative to the second device of the second type that lacks the capability. The base station may modulate data from the region of the subframe for transmission to the first and the second devices, using a hierarchical modulation scheme.
