    Abstract: Current 5G provisions for wireless communications do not allow for the differentiation of channel access by User Equipments (UEs) with different priorities. Approaches are described by which priority access for UEs in a controlled environment using frame based equipment (FBE), and in particular for different UEs or the same UE that has different configured grants. The approaches are particularly helpful for ultra-reliable low-latency communication (URLLC) UEs. In one approach, the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP), followed by a channel access priority test. In an alternative approach, the UE performs a channel access priority test before the UE performs a clear channel assessment (CCA) in an idle period before the fixed frame period (FFP). Other approaches include setting the fixed frame period length to different sizes for each UE, using a random number of skipped fixed frame periods, and the gNB configuring UEs with multiple semi-static channel access mode parameters.

    Abstract: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP. The UE may determine RACH information related to the second TRP, based at least partly on the specified DL TCI related to the second TRP included in the handover command and the DL TCI list. The UE may then perform random access to the second TRP based on the RACH information related to the second TRP. The RACH information may include uplink (UL) beam information, RO information and Bandwidth Part (BWP) information for the UE to perform random access to the second TRP.

    Abstract: A user equipment (UE) receives TCI state configurations for a plurality of signals, wherein a first state configuration comprises a first port for a first signal being quasi-co-located (QCL) to a second port of a second signal and a second state configuration comprises the second port of the second signal being QCL to a third port of a third signal and determines a TCI chain comprising the first, second and third signals so that channel measurements for each one of the first, second and third signals are applied to channel measurements for each other one of the first, second and third signals, wherein at least one of the first, second or third signals is an uplink (UL) signal.

    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a use equipment (UE) to determine, based on a transmission configuration indicator (TCI) state, a sensing beam to wirelessly communicate with a base station over a channel in an unlicensed spectrum. The UE can receive, using a receiving beam, control information including a TCI state, determine a sensing beam indicated by the TCI state included in the control information, sense a channel occupancy of the channel between the UE and the base station by performing Clear Channel Assessment using the sensing beam. Furthermore, the UE can determine, based on the channel occupancy, whether the channel is free to be utilized for communication by the UE using the sensing beam.
