Uplink design for narrowband LTE (NB-LTE)

摘要

Aspects of this disclosure provide techniques for wireless communication by a base station. An example method generally includes one or more of communicating with a BS on a first frequency band that is narrower than a second frequency band used to communicate with a second type of user equipment (UE). Allocating uplink resources to the first type UE, wherein the uplink resources are the same or different symbol duration and the same or different time as the uplink resources allocated to the second type UE. Receiving uplink transmissions from the first type UE on the allocated resources, allocated using granularity and using a single subcarrier allocated to the first type UE. [Selection] Figure 21
