Abstract: In an example method, a user equipment (UE) device determines an offset length of time associated with transmitting or receiving data over a wireless network. The UE device transmits an indication of the offset length of time to the wireless network. The UE device transmits or receives, during a first time interval, a first portion of data to or from the wireless network though a first wireless link. The UE device transmits or receives, during a second time interval, a second portion of data to or from the wireless network though a second wireless link. An end of first time interval is offset from a beginning of the second time interval by the offset length of time.

Abstract: Techniques discussed herein can facilitate configuration of a User Equipment (UE) with two or more Discontinuous Reception (DRX) configurations. A first set of techniques can facilitate configuration of the UE with independent DRX configurations for Frequency Range 1 (FR1) and for Frequency Range 2 (FR2). A second set of techniques can facilitate configuration of the UE with independent DRX configurations for a first set of one or more Component Carriers (CCs) associated with a first frequency band of a supported band combination and for a second set of one or more CCs associated with a second frequency band of the supported band combination. Various embodiments can employ techniques of one or more of the first set of techniques or the second set of techniques.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE,106) and/or cellular network (100) to perform cell detection and measurement, e.g., in new radio (NR) unlicensed (NR-U). The UE (106) may determine that a threshold condition related to missed reference signal opportunities is reached. In response, the UE (106) may modify reference signal monitoring and/or measurement.

Abstract: Some embodiments include systems, apparatuses, methods, and computer-readable media for use in a wireless network for determining a reception (Rx) beam sweep scale factor, N, that enables a user equipment (UE) to perform Rx beam refinement. Some embodiments are directed to a 5G Node B (gNB) that includes processor circuitry and radio front end circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, a MaxNumberRxB cam capability of the UE. The processor circuitry can determine based at least on the MaxNumberRxBeam capability of the UE and/or a Channel-State Information (CSI)- reference signal (RS) set with a repetition parameter configured to be 'ON', the value of N. The processor circuitry can generate a message comprising the value N, and encode the message for transmission to the UE, where N Rx beam sweeps enable the UE to perform Rx beam refinement.

Abstract: This disclosure describes methods, systems, and devices for handover of a user equipment (UE) from a source node of a radio access network (RAN) to a target node of the RAN. In one example, a method involves receiving, by the UE and from the source node, a RACH-498 handover message comprising: (i) an uplink grant for establishing a connection with the target node, and (ii) an identifier of a reference signal associated with a beam of the target node. The method also involves performing, by the UE, a handover based on the RACH-less handover message.

Abstract: One or more methods of operating an access node. At least one of the methods includes: detecting a capability indication that indicates a capability of a user equipment (UE) to simultaneously receive and transmit (Rx/Tx) on a first component carrier (CC1) and a second component carrier (CC2); and scheduling, based at least on the capability, a first UE activity to occur over the CC1 and a second UE activity to occur over the CC2 to avoid a collision in a time-domain by prioritizing one of the first UE activity or the second UE activity relative to the other one of the first UE activity or the second UE activity.

Abstract: Systems, devices, and techniques for measuring and reporting cross-link interference (CLI) are described. A described technique includes determining, by a first wireless device, whether to perform a CLI measurement; determining a quantity of activated transmission configuration indicator (TCI) states associated with a second wireless device; performing the CLI measurement based on the quantity of activated TCI states; and transmitting a CLI report in response to the CLI measurement.

Abstract: A system, method, and apparatus is provided for performing carrier aggregation (CA) radio resource management (RRM). The system, method, and apparatus can receive a configuration message having configuration information from an access node; determine a measurement period for a secondary cell (SCell) and a cell identification delay based upon the configuration information; identify a new detectable cell on a secondary component carrier (SCC) as the SCell within the cell identification delay; perform a measurement for a CA operation within the measurement period; and report the measurement to the access node. The configuration message can be a Radio Resource Control (RRC) message. The measurement for the CA operation can be a measurement of the SCell on the SCC. The system, method, and apparatus can multiply a measurement control parameter by a factor less than five (5) to determine the measurement period and can multiply a measurement control parameter by a factor less than twenty (20) to determine the cell identification delay. The system, method, and apparatus can further perform an action with respect to the SCell in response to the measurement.

Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for scheduling intra-frequency measurements. Some embodiments are directed to a user equipment (UE). The UE includes processor circuitry and radio front circuitry. The processor circuitry can be configured to determine a collision signal status between an intra-frequency measurement signal and an uplink transmission signal. The processor circuitry can be further configured to determine a measurement gap status of the LIE. Moreover, the processor circuitry can be further configured to prioritize between the SSB measurement signal and the uplink transmission signal based on the collision signal status and the measurement gap status. Additionally, the processor circuitry can be further configured to perform a wireless measurement according to the prioritization between the intra-frequency measurement signal and the uplink transmission signal.
