  • Patent number: 12262320
    Abstract: Techniques for fast adaptation of PDCCH monitoring by a UE via L1 signaling in order to reduce power consumption by the UE are disclosed. A base station sends first configuration information to a user equipment (UE) via higher layer signaling (e.g. RRC) to configure downlink control channel monitoring by the UE. Thereafter, the base station may send downlink control information to the UE via L1 signaling to adapt the PDCCH monitoring by the 6 UE. The downlink control information may temporarily override or modify the parameters for PDCCH monitoring set by higher layers. The downlink control information may be send in an existing downlink control message or in a new downlink control message.

    Abstract: Systems and methods are disclosed herein for transitioning between different scheduling delay assumptions. In some embodiments, a method performed by a wireless device comprises monitoring, during a first slot, for a downlink control channel comprising downlink control information that schedules a transmission for the wireless device with an assumption of a first scheduling delay that is equal to or exceeds a first value. The method further comprises determining that the wireless device is to switch from the assumption of the first scheduling delay to an assumption of a second scheduling delay that is equal to or exceeds a second value that is less than the first value. The method further comprises monitoring, during one or more later slots that occur after the first slot, for a downlink control channel comprising downlink control information that schedules a transmission for the wireless device with the assumption of the second scheduling delay.

  • Publication number: 20240357610
    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.
