Abstract: Embodiments of a user equipment (UE) for reporting of timing offset for dual connectivity enhancement are disclosed herein. The UE can include transceiver circuitry to connect to a master cell group via a master evolved node B (eNB) and a secondary cell group via a secondary eNB. Additionally, the UE can receive a first reference signal from the master eNB and a N second reference signal from a secondary eNB. Moreover, the UE can include processing circuitry to calculate a system frame number (SFN) and subframe timing difference (SSTD) based on the first reference signal and the second reference signal. Moreover, the UE can generate a measurement report having a synchronization indicator for dual connectivity based on the calculated SSTD. Subsequently, the UE can send the generated measurement report to the master eNB.

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: Some aspects of this disclosure relate to apparatuses and methods for implementing downlink transmission and interlace uplink transmission. For example, some aspects of this disclosure relate to a base station including a transceiver configured to communicate over a wireless network with a user equipment (UE) and a processor communicatively coupled to the transceiver. The processor divides a plurality of candidate Synchronization Signal Block (SSB) positions in a time window into a plurality of groups and communicates, using the transceiver, information associated with the plurality of groups of candidate SSB positions to the UE. The processor further performs a listen-before-talk (LBT) procedure. In response to the LBT procedure being successful, the processor determines a first group of the plurality of groups and transmits, using the transceiver, one or more SSBs on one or more candidate SSB positions of the first group to the UE.

Abstract: A user equipment (UE) device is configured for performing a signal measurement for wireless communication in a new radio (NR) network. The UE is configured to determine a frequency range (FR) of a serving cell configured to send a signal that is measured by the UE using a signal measurement. The UE configures a measurement gap (MG) pattern to perform the signal measurement. Configuring the measurement gap includes determining that the frequency range of the serving cell includes frequencies of a second frequency range (FR2), determining that a measurement object (MO) configuration for the FR2 is available, setting a measurement gap repetition periodicity (MGRP) value for the signal measurement, and setting a measurement gap length (MGL) value for the signal measurement. The UE performs a signal measurement using the MGRP value and the MGL value.

Abstract: Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.
