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: 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: 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.

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: In at least one embodiment, a user equipment (UE) may receive a control signal from a base station to update a target pathloss reference signal from an existing pathloss reference signal. In at least one embodiment, the UE may obtain a plurality of samples of the target pathloss reference signal. In at least one embodiment, the UE may determine, based on obtaining the plurality of samples of the target pathloss reference signal, that the UE is unable to update the target pathloss reference signal. In at least one embodiment, the UE may adjust the uplink transmission power of the UE based on the existing pathloss reference signal or to a maximum transmit power based on said determining that the UE is unable to be updated to the target pathloss reference signal.

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: A UE may receive multiple signals causing a Quasi co-location TypeD (QCL-TypeD) collision. To determine which of the multiple signals to select, the UE may use a certain option based on a type transmission scheme associated with each of the multiple signals. The options may include one of a priority rule for signal reception, a scheduling restriction, or a priority rule for QCL-TypeD selection.
