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: A user equipment (UE) is provided having a memory to store a measurement object (MO) that defines a synchronization-signal block based measurement timing configuration (SMTC) occasion. The MO is within a group of MOs that include SMTC configurations that provide fully overlapped SMTC occasions. The UE further includes processing circuitry to determine an inter-frequency cell identification requirement for the group and perform measurements based on the MO to determine whether a cell is detected within the inter-frequency cell identification requirement.

Abstract: Systems and methods are described for configuring cell identification requirements for a user equipment (UE). The systems and methods can include at least determining a number of measurement objects (MOs) that collide with a target MO for the UE, determining a scaling factor to be used for an inter-frequency cell identification requirement, and transmitting to the UE an indication of the scaling factor.

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: This disclosure describes methods, systems, and devices for measuring a reference signal received power (RSRP) in a user equipment (UE) that operates in machine type communication (MTC). In one example, a method involves receiving, from a radio access network (RAN) serving the UE, a resynchronization signal (RSS). The method also involves calculating a reference signal received power (RSRP) of the RSS.

Abstract: Methods, systems, apparatus, and computer programs, for implementing dual-connectivity handover. In one aspect, a method includes determining, by user equipment (UE), whether the UE is capable of simultaneous communication with a source cell and a target cell, generating, by the UE, a handover indicator, the handover indicator having one or more fields structuring data that indicates that the UE is capable of simultaneous communication with the source cell and the target cell, transmitting, by the UE, the handover indicator to an access node, and receiving, by the UE and from the access node based on receipt by the access node of the handover indicator, a command to perform handover.
