  • Patent number: 11997601
    Abstract: Exemplary embodiments include methods for a user equipment (UE) to receive a wake-up signal (WUS) via downlink control information (DCI) transmitted by a network node in a radio access network (RAN). Such methods include receiving a physical downlink control channel (PDCCH) from the network node, and processing the received PDCCH to determine if it includes a DCI carrying a WUS targeted to the UE. The processing can include determining if a payload portion of the DCI is based on a first function of an identifier associated with the UE (e.g., C-RNTI) or with a group of UEs (e.g., WUG-RNTI). The processing can also include determining if a cyclic redundancy check (CRC) portion of the DCI is based on a second function of the identifier. Other embodiments include complementary methods performed by a network node, and UEs or network nodes configured to perform the exemplary methods.

  • Patent number: 11956740
    Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

  • 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.
