    Abstract: Apparatuses, systems, and methods for mitigation of listen before talk conflicts in the unlicensed spectrum. A wireless device may receive one or more synchronization signal blocks (SSBs) from a base station (BS) as part of a measurement procedure with listen before talk (LBT). The wireless device may determine one or more LBT failures associated with one or more receive beams of the wireless device. Furthermore, in response to determining the one or more LBT failures associated with the one or more receive beams of the wireless device, the wireless device may extend a measurement period for the one or more receive beams of the wireless device. The wireless device may then receive one or more additional SSBs on the one or more receive beams of the wireless device.

    Abstract: Disclosed are methods, systems, apparatus, and computer programs for a coordination mechanism between a network and a user equipment (UE) that is configured to perform cross-link interference (CLI) measurements. In one aspect, a method includes generating a message that indicates a capability of a user equipment (UE) whether to support simultaneous reception of at least one signal associated with cross-link interference (CLI) measurement and at least one signal associated with a serving cell or a neighbor cell of the UE. The method further includes transmitting the message to an access node (AN).

    Abstract: Embodiments include a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. The operations include receiving a downlink channel information (DCI) format 2_0 from a g-NodeB (gNB) connected to the 5G NR network, wherein the DCI format 2_0 includes channel occupancy time (COT) duration and a gap threshold value, determining if a nonzero power channel state information reference signal (NZP-CSI-RS) resource is valid, wherein the NZP-CSI-RS resource is valid if the NZP-CSI-RS resource is within the COT duration and if a gap between a last symbol of the DCI format 2_0 and a first symbol of the NZP-CSI-RS resource is greater than the gap threshold value.

    Abstract: Techniques discussed herein facilitate generation of uplink control information for Enhanced Physical Uplink Control Channel (PUCCH) Format(s) (EPF(s)). One example embodiment employable in a User Equipment (UE) is configured to: determine Hybrid Automatic Repeat reQuest-Acknowledgment (HARQ-ACK) information; generate a PUCCH for a BandWidth Part (BWP) based at least in part on the HARQ-ACK information, wherein the PUCCH has an EPF; determine a PUCCH resource for the PUCCH and a first PRB index for the PUCCH, wherein the PUCCH resource is determined based at least in part on an index of a first Control Channel Element (CCE) of an associated Physical Downlink Control Channel (PDCCH) and a number of CCEs in a Control Resource Set (CORESET) of the associated PDCCH; and map the PUCCH to at least one PUCCH interlace based on the PUCCH resource and the first PRB index for the PUCCH.

    Abstract: Systems, apparatuses, methods, and computer-readable media are provided for facilitating handoff of a User Equipment, engaged in beamforming, by communicating beam information between a first access point (AP) to a second AP. The first AP associated with a serving cell of the UE includes processor circuitry and interface circuitry. The processor circuitry is configured to determine that the UE device is expected to associate with the second AP and identify a synchronization signal block (SSB) index associated with the first AP. The processor circuitry is further configured to generate a message that includes the SSB index to enable the second AP to pre-configure downlink and uplink resources for the UE before the UE associates with the second AP. The interface circuitry is coupled to the processor circuitry and configured to communicate the message to the second AP.
