UPLINK DESIGN FOR NARROWBAND LTE (NB-LTE)

摘要

Aspects of the present disclosure provide techniques for wireless communications by a base station. An example method generally includes allocating uplink resources to one or more first type of user equipments (UEs) that communicate with the BS on a first frequency band that is narrower than a second frequency band used to communicate with a second type of UE, wherein the uplink resources may be allocated with a same or different symbol duration and same or different time granularity as uplink resources allocated to the second type of UE and with single subcarriers allocated to the first type of UEs, and receiving uplink transmissions from the first type of UE on the allocated resources.

1. A method for wireless communications by a base station (BS), comprising:
allocating uplink resources to one or more first type of user equipments (UEs) that communicate with the BS on a first frequency band that is narrower than a second frequency band used to communicate with a second type of UE, wherein the uplink resources are allocated in a narrowband subframe structure with an increased symbol duration relative to uplink resources allocated to the second type of UE and wherein symbols in the narrowband subframe structure are aligned with a boundary of a set of multiple subframe structures used to communicate with the second type of UE; and receiving uplink transmissions from the first type of UE on the allocated resources.
