  • Patent number: 11963195
    Abstract: Disclosed herein are timing determination techniques for 5G radio access network (RAN) cells. According to various such techniques, during a random access procedure, a user equipment (UE) may receive a grant of resources for an uplink (UL) data transmission in a random access response (RAR) message. The UE may identify a scheduled slot for the UL data transmission based on a received slot of the RAR message and an applicable slot offset value. The applicable slot offset value may indicate a number of slots by which the received slot precedes the scheduled slot. The applicable slot offset value may be identified using the various techniques described herein.

  • 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.

  • Patent number: 11910470
    Abstract: An indication of a first energy detection threshold for a first clear channel assessment (CCA) can be received at a mobile device from a cell operating on an unlicensed carrier. The first energy detection threshold can be different than a second energy detection threshold for a second CCA at a network entity of the cell. A determination can be made as to whether the unlicensed carrier is occupied based upon the first CCA and the received first energy detection threshold. A data packet can be communicated between the mobile device and the cell when the unlicensed carrier is not otherwise occupied.
