Abstract: A system for switching an uplink waveform for a wireless device in a wireless network includes an access node configured to deploy a first radio air interface to provide wireless services to the wireless device. The access node includes a processor configured to receive a signal indicating a channel condition from the wireless device. The processor is also configured to determine whether to switch the uplink waveform for the wireless device based on the signal indicating the channel condition.

Abstract: A system for selecting a sub-carrier spacing includes an access node configured to deploy a radio air interface to provide wireless services to a plurality of wireless devices. The access node includes a processor configured to determine a value of at least one parameter relating to at least one of radio frequency impairment, mobility, and service latency. The processor is also configured to compare the value of the at least one parameter with a predetermined threshold. The processor is further configured to select the sub-carrier spacing from a plurality of sub-carrier spacings based on a result of the comparison.

Abstract: Systems for wireless communication between a wide bandwidth network node and a narrow bandwidth wireless device are configured to perform operations including determining a maximum channel bandwidth of the narrow bandwidth wireless device, configuring at least two bandwidth parts (BWPs) within a single carrier deployed by the wide bandwidth network node, scheduling a data transmission between the wide bandwidth network node and the narrow bandwidth wireless device within the at least two BWPs, and instructing the narrow bandwidth wireless device to aggregate the at least two BWPs within the single carrier to receive the data transmission.
