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: In at least one embodiment, a user equipment (UE) may receive a control signal from a base station to update a target pathloss reference signal from an existing pathloss reference signal. In at least one embodiment, the UE may obtain a plurality of samples of the target pathloss reference signal. In at least one embodiment, the UE may determine, based on obtaining the plurality of samples of the target pathloss reference signal, that the UE is unable to update the target pathloss reference signal. In at least one embodiment, the UE may adjust the uplink transmission power of the UE based on the existing pathloss reference signal or to a maximum transmit power based on said determining that the UE is unable to be updated to the target pathloss reference signal.

Abstract: A method of a user equipment (UE) performing cell re-selection in New Radio (NR) unlicensed (NR-U) idle mode includes performing cell re-selection associated with a selected public land mobile network (PLMN) in New Radio (NR) unlicensed (NR-U) idle mode. Performing cell re-selection in NR-U idle mode further comprises determining a best cell associated with the selected PLMN based on one or more measurements. At least one of the one or more measurements may comprise a channel occupancy measurement. Performing cell re-selection in NR-U idle mode further comprises camping on the best cell and periodically searching for cells that are determined to be better than the best cell based on the one or more measurements.

Abstract: An approach is described for a user equipment (UE) that includes radio front end circuitry and processor circuitry. The front end circuitry receives an indication from a network entity node, wherein the indication is indicative of a first fraction for a first radio resource management (RRM) procedure and a second fraction for a second RRM procedure. The processor circuitry performs a first measurement of the first RRM procedure in a first fraction of a measurement period. The processor circuitry further performs a second measurement of the second RRM procedure in a second evaluation period, wherein the second evaluation period is the second fraction of the measurement period.

Abstract: A UE may receive multiple signals causing a Quasi co-location TypeD (QCL-TypeD) collision. To determine which of the multiple signals to select, the UE may use a certain option based on a type transmission scheme associated with each of the multiple signals. The options may include one of a priority rule for signal reception, a scheduling restriction, or a priority rule for QCL-TypeD selection.

Abstract: Devices, systems, and methods for Random Access Channel (RACH) configuration in Layer 1 (L1)/Layer 2 (L2) mobility. A user equipment (UE) may obtain a downlink (DL) Transmission Configuration Indicator (TCI) list from a first Transmission and Reception Point (TRP). The DL TCI list may include DL beam information, RACH Occasion (RO) information, and initial Bandwidth Part (BWP) information associated with each DL TCI of a plurality of DL TCIs related to the first TRP and multiple TRPs adjacent to the first TRP. The UE may receive a handover command from the first TRP via Downlink Control Information (DCI) in Li or Media Access Control (MAC) Control Element (CE) in L2. The handover command indicates a handover from the first TRP to a second TRP of the multiple TRPs for the UE, and includes a specified DL TCI related to the second TRP. The UE may determine RACH information related to the second TRP, based at least partly on the specified DL TCI related to the second TRP included in the handover command and the DL TCI list. The UE may then perform random access to the second TRP based on the RACH information related to the second TRP. The RACH information may include uplink (UL) beam information, RO information and Bandwidth Part (BWP) information for the UE to perform random access to the second TRP.

Abstract: Aspects are presented herein of apparatuses, systems, and methods for measurement gap configuration. A cellular network may establish communication with a UE using a first and second cell. The cellular network may configure bandwidth parts (BWPs) for the first and second cell, including a first and second BWP for the first cell and a third and fourth BWP for the second cell. A measurement gap configuration that specifies when the UE is to use a first measurement gap pattern may be provided to the UE. At a first time, the cellular network may communicate with the UE using the first BWP for the first cell and the third BWP for the second cell, based on the first measurement gap pattern. At a second time, the cellular network may communicate with the UE using the second BWP for the first cell based on a modification of the first measurement gap pattern.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for apparatuses and methods for providing continuous communication services for a user equipment (UE) connected to a non-terrestrial network (NTN) and/or one or more satellites providing cellular coverage. The UE may receive a list of neighbor cells from a serving cell, which may be a satellite moving relative to the Earth and having a moving coverage area. After receiving the list of neighbor cells, the UE may sort the list to prioritize the neighbor cells. This sorting may be based on a calculated distance between the UE and each of the neighbor cells. The UE may sequentially perform a synchronization and measurement process with each of the neighbor cells or a subset of the neighbor cells based on the prioritization order. The UE may then establish communications with a target cell from the prioritized list to maintain continuity.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.
