Title: INTEGRATING LTE AND NEW RADIO
Abstract:
Techniques for wireless communications in a system with long term evolution (LTE) integrated with new radio (NR) are provided. A method for wireless communications includes determining a configuration of component carrier(s) (CCs) of a first radio access technology (RAT) and CC(s) of a second RAT. The method also includes identifying one of the CC(s) in the first RAT as an uplink anchor CC based on the configuration. The method further includes identifying a HARQ timing for at least one of the CC(s) of the second RAT based on at least one of a symbol duration, a transmit time interval (TTI) length or a subframe structure of the one of the CC(s) of the first RAT. The method further yet includes sending feedback to a second node in the identified uplink anchor CC for transmissions received in the CC(s) of the second RAT.
