Abstract:
Aspects of the present disclosure provide techniques for configuring multi-beam full-duplex communication that allows a device (e.g., user equipment (UE) or base station) to contemporaneously perform both uplink and downlink communication over the same frequency band. Because of the full duplex communication capability provided by the present disclosure, the NR system may achieve reduced latency and improved spectrum and resource efficiency, thereby accommodating a growing demands for the wireless communication. The full duplex communication capability may be achieved by implementing downlink control information (DCI) format that specifies to the UE the beam assignments for contemporaneous transmission (Tx) and reception (Rx). Particularly, beams may be selected such that the beam(s) assigned for communication are independent and uncorrelated, and therefore provide sufficient beam diversity in order to mitigate the limitations of current systems, including self-interference that has hindered implementation of full duplex communication in current systems.
