  • Publication number: 20210345376
    Abstract: Embodiments of this disclosure provide techniques for communicating in a wireless communications system. In particular, in an embodiment a base station receives a capability message from a user equipment (UE) indicating downlink scheduling delay. The base station transmits a downlink control frame to the UE in response to determining that transmitting a frame to the UE satisfies a scheduling delay condition. The downlink control frame indicates a scheduling delay of the frame equal to or greater than the downlink scheduling delay. The base station then transmits the frame to the UE in accordance with the downlink control frame.
