  • Publication number: 20240089978
    Abstract: Techniques disclosed herein efficiently address prioritization by a UE regarding its reception behavior with respect to a configured downlink transmission that is overlapped by a dynamic assignment and/or the dynamic downlink transmission scheduled via the dynamic assignment. In at least one embodiment having applicability to operation of the UE in a communication network based on the 5G NR specifications, the techniques disclosed herein provide for predictable behavior by the UE as to when the UE prioritizes a configured Physical Downlink Shared Channel (PDSCH) versus another PDSCH. Correspondingly, a radio network node may exploit the predictable behavior of the UE to override a configured PDSCH in favor of a dynamic PDSCH, by transmitting the Physical Downlink Control Channel (PDCCH) that schedules the dynamic PDSCH so that a timing relationship between the PDCCH and the configured PDSCH is satisfied.
