    Abstract: A device of a New Radio (NR) User Equipment (UE), a system, a method and a machine-readable medium. The device includes a radio frequency (RF) interface and processing circuitry coupled to the RF interface. The processing circuitry is to: cause communication with a NR evolved Node B (gNodeB) on a first bandwidth part (BWP); determine a BWP switching delay for an uplink (UL) communication from the UE to the gNodeB, the BWP switching delay based on a timing advance (TA) for the UL communication; encode the UL communication for transmission to the gNodeB; switch from the first BWP to a second BWP at an expiration of the BWP switching delay; and cause transmission of the UL communication on the second BWP.

    Abstract: A method of a user equipment (UE) performing cell re-selection in New Radio (NR) unlicensed (NR-U) idle mode includes performing cell re-selection associated with a selected public land mobile network (PLMN) in New Radio (NR) unlicensed (NR-U) idle mode. Performing cell re-selection in NR-U idle mode further comprises determining a best cell associated with the selected PLMN based on one or more measurements. At least one of the one or more measurements may comprise a channel occupancy measurement. Performing cell re-selection in NR-U idle mode further comprises camping on the best cell and periodically searching for cells that are determined to be better than the best cell based on the one or more measurements.

    Abstract: An approach is described for a user equipment (UE) that includes radio front end circuitry and processor circuitry. The front end circuitry receives an indication from a network entity node, wherein the indication is indicative of a first fraction for a first radio resource management (RRM) procedure and a second fraction for a second RRM procedure. The processor circuitry performs a first measurement of the first RRM procedure in a first fraction of a measurement period. The processor circuitry further performs a second measurement of the second RRM procedure in a second evaluation period, wherein the second evaluation period is the second fraction of the measurement period.

    Abstract: An electronic device may receive, from a radio node, a measurement configuration associated with a wireless communication system. In response, the electronic device may perform measurements using narrow beam patterns based at least in part on a network configuration, where the narrow beam patterns are narrower than a wide beam pattern of the electronic device. Furthermore, performing the measurements using the narrow beams pattern may include performing a beam-pattern search up to the network configuration. Then, the electronic device may perform an SCell activation procedure of an SCell with the radio node. Note that the SCell activation procedure may include reporting, to the radio node, CSI of a narrow beam pattern of the SCell that is to be activated, where the narrow beam pattern is narrower than the wide beam pattern of the electronic device, and the narrow beam pattern is based at least in part on the measurements.

    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).
