    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: 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.

    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: User equipment performs autonomous time adjustment that includes selecting a Timing Error Limit (i.e. Te_NR) and Maximum Autonomous Time Adjustment Step (i.e. Tq_NR) based on bandwidth (BW) and subcarrier spacing (SCS). In one embodiment, given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=x/2(kHz) is 2*N. Given a certain downlink BW, if the SCS=x(kHz) and the Te_NR of this SCS is N, then the Te_NR of SCS=2*x(kHz) is N/2. For example, given BW=10 MHz, if the Te_NR of SCS=30kHz is n*Ts_NR (TS_NR is the basic timing unit for NR system), then the Te_NR of SCS=60 kHz is N/2*Ts_NR, and the Te_NR of SCS=15 kHz is 2*N*Ts_NR.

    Abstract: Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for cell identification (ID) and beam ID detections in new radio (NR). The detections comprise NR primary synchronization signal (PSS)/secondary synchronization signal (SSS) detection, PBCH DMRS detection, SS reference signal received power (RSRP) measurement, and slot/SS burst boundary timing acquiring. Various embodiments describe how to detect a cell ID and a beam ID in millimeter wave (mmWave) operation. Other embodiments describe further details regarding how to detect NR cell and beam ID during intra-frequency measurements.
