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: Systems and methods provide for beam detection in a wireless communication system. An apparatus for a UE may be configured to identify a plurality of CSI-RS resources corresponding to different Tx beams configured for measurement by the UE, measure an L1-RSRP for the plurality of CSI-RS resources, determine a selected Tx beam of the different Tx beams based on measured L1-RSRP values for the plurality of CSI-RS resources, and determine a measurement accuracy of a first L1-RSRP value corresponding to the selected Tx beam based on successful beam detection probability.

Abstract: A method for enhanced autonomous uplink timing adjustment includes determining that a user equipment (UE) is traveling above a predetermined velocity. In response to the determination that the UE is traveling above the predetermined velocity, a maximum aggregate adjustment rate to an uplink timing for the UE and a maximum amount of a magnitude of a timing change to the uplink timing for the UE are determined. The uplink timing for the UE is adjusted based on the maximum aggregate adjustment rate and the maximum amount of the magnitude of the timing change.

Abstract: An apparatus of a user equipment (UE) comprises one or more baseband processors to process a bandwidth part (BWP) switching request from a serving cell at slot n, and to perform an active BWP switch to a new BWP on the serving cell at a time no later than slot n+Y, wherein Y is a BWP switching delay. The one or more baseband processors are to accommodate a timing advance (TA) value to determine when to perform the active BWP switch. The apparatus can include a memory to store the BWP switching request.

Abstract: The present disclosure is directed to systems and methods for determining a starting point of a measurement gap. For example, the present disclosure is directed to a user equipment (UE) that includes a memory and processor circuitry coupled to the memory. The processor circuitry may be configured to receive an indication of a measurement gap timing advance. The processor circuitry may be further configured to, based on the indication of the measurement gap timing advance, determine a starting point of a measurement gap in a dual connectivity mode that provides dual connectivity with a new radio (NR) and an evolved universal mobile telecommunications system terrestrial radio access (EUTRA). The NR may serve as a master Radio Access Network (RAN) and the EUTRA may serve as a secondary RAN. The processor circuitry may also be configured to perform a signal quality measurement during the measurement gap, wherein the signal quality measurement is performed on a target cell of the NR or EUTRA.
