Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.

Handover in dual connectivity to a primary base station and a secondary base station

A user equipment (UE) is connected to a 5G New Radio (NR) network via a serving cell. The UE performs radio resource management (RRM) measurements on the serving cell, determines whether the UE satisfies power saving criteria for a first, second, or third mobility scenario while in a Radio Resource Control (RRC) idle state or RRC inactive state, wherein, when the UE is in the first or second mobility scenario, the UE performs RRM measurements with longer intervals relative to RRM measurements performed in a non-power-saving mode and wherein, when the UE is in the third scenario, the UE performs RRM measurements for neighbor cells with longer intervals relative to RRM measurements performed in a non-power-saving mode and determines a UE RRM configuration when the UE transitions from any of the power saving scenarios or the non-power-saving mode to any other power saving scenarios or the non-power-saving mode.

Radio resource management in power saving mode

Some embodiments include systems, apparatuses, methods, and computer-readable media for use in a wireless network for determining a reception (Rx) beam sweep scale factor, N, that enables a user equipment (UE) to perform Rx beam refinement. Some embodiments are directed to a 5G Node B (gNB) that includes processor circuitry and radio front end circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, a MaxNumberRxB cam capability of the UE. The processor circuitry can determine based at least on the MaxNumberRxBeam capability of the UE and/or a Channel-State Information (CSI)-reference signal (RS) set with a repetition parameter configured to be 'ON', the value of N. The processor circuitry can generate a message comprising the value N, and encode the message for transmission to the UE, where N Rx beam sweeps enable the UE to perform Rx beam refinement.

Reception (RX) beam sweep scale factor

A technique for wireless communications in a wireless system including: receiving, by a wireless device, a request to perform a pathloss reference signal (PLRS) measurement procedure in an unlicensed band, wherein the wireless device is configured to accumulate a first number of PLRS measurements within a PLRS switching period to perform the PLRS measurement procedure, wherein the first number of PLRS measurements is more than one, measuring, by the wireless device, a second number of PLRS signals during the PLRS switching period, wherein the second number is less than the first number of PLRS measurements within the PLRS switching period, determining, by the wireless device, to extend the PLRS switching period, and listening, by the wireless device, for a PLRS signal during the extended PLRS switching period.

Techniques for pathloss reference signal measurement in unlicensed bands

The disclosure relates to Discontinuous Reception (DRX) based UE behavior. A user equipment (UE) is configured to perform operations comprising: obtaining a first DRX cycle; determining a second DRX cycle at least based on the first DRX cycle and a DRX cycle threshold, wherein the DRX cycle threshold is a highest value of DRX cycle that can support LEO (Low-Earth Orbit) cell measurement; and applying the second DRX cycle, comprising applying the second DRX cycle to measurement of at least one LEO cell of the serving cell and a neighbor cell, wherein at least one of the serving cell and the neighbor cell is a LEO cell.

DRX based UE behavior

A user equipment (UE) is provided to select an uplink transmission beam to communicate with a base station in a secondary cell of a carrier aggregation (CA) scheme. The UE can communicate with a first base station in a primary cell (PCell), and receive a command from the wireless network to activate a physical uplink control channel (PUCCH) transmission to a second base station in a secondary cell (SCell). The second base station can be in a being-activated state. The UE can determine whether an uplink spatial relation configuration is provided to the UE, and determine whether the UE supports beam correspondence. Based on the determinations, the UE can select an uplink transmission beam for the PUCCH transmission to the second base station.

Uplink transmission beam selection in a secondary cell

This disclosure relates to techniques for performing wireless communications including exchanging information related to capability of processing reference signals. A user equipment device may provide capability information to a network. The capability information may indicate a number of reference signal resources that the user equipment device can process in a slot or other defined period of time. The user equipment device and the network may share a common set of definitions, counting rules, and approaches for interpreting the capability information. The network may configure reference signals for the user equipment device.

Resource counting for reference signals

This disclosure relates to techniques for configuring, performing, and reporting neighbor cell measurements in a wireless communication system. A base station of a serving cell may provide configuration information relevant to performing layer 1 (L1) measurements based on reference signals of one or more neighbor cells. A UE may perform L1 inter-frequency measurements of the neighbor cell(s) based on the configuration. The UE may report the measurements.

Neighbor cell measurements

The present application relates to devices and components including apparatus, systems, and methods for radio link monitoring and/or beam failure detection operations in wireless communication systems.

Reference signal transition for radio link monitoring and beam failure detection

Systems, apparatuses, methods, and computer-readable media are provided for radio link monitoring (RLM) evaluation period and layer 1 (L1) indication interval enhancements. A user equipment (UE) uses a scaling factor to scale the RLM evaluation period and/or the L1 indication interval. Different scaling factors may be used for different scenarios, conditions, or criteria. The same or different scaling factors may be used for the RLM evaluation period and the L1 indication interval. The scaling factor or a scaling factor index may be signaled to the UE by higher layer signaling. Other embodiments may be described and/or claimed.

Radio link monitoring enhancements for power savings

A user equipment (UE) configured to collect UE positioning information configured to indicate a location of the UE, wherein the UE is deployed onboard an airplane and report the UE positioning information to a cell of a non-terrestrial network (NTN). Also, a user equipment (UE) configured to receive a request for uplink positioning reference signals, wherein the uplink positioning reference signals are to indicate a location of the UE and wherein the UE is deployed on an airplane and transmit the uplink positioning reference signals to a cell of a non-terrestrial network (NTN).

Collecting UE positioning information in a non-terrestrial network

A method performed by a user equipment (UE) for enhanced radio resource management (RRM) includes communicating, to an access node, a capability of the UE to support bandwidth part (BWP) without restriction. The UE determines that a synchronization signal block (SSB) is outside a downlink (DL) BWP configured for the UE. Based on determining that the SSB is outside the DL BWP configured for the UE, at least one radio frequency (RF) communication parameter of the UE is adjusted to adjust an operating bandwidth of the UE, and the SSB is received using the adjusted operating bandwidth.

Enhanced radio resource management for synchronization signal blocks outside an active bandwidth part

A terminal may include a transmitter that transmits, to a base station, a terminal capability indicating support for a first type of measurement configuration or a second type of measurement configuration. The terminal may include a receiver that receives, from the base station, network configuration information representative of a mapping between the first type of measurement configuration and the second type of measurement configuration. The terminal may include a processor that, based on the mapping, transforms the first type of measurement configuration to the second type of measurement configuration or transforms the second type of measurement configuration to the first type of measurement configuration. The network configuration information may be based on an independent frequency range (FR) measurement and a network preference included in the terminal capability.

Terminal, base station, and method for transforming a measurement configuration

Systems, devices, and techniques for wireless communications based on one or more transmission configuration indicator (TCI) states are described. A described technique performed by a user equipment (UE) includes receiving a first downlink channel based on a current TCI state; receiving a physical downlink shared channel (PDSCH) in a first slot, the PDSCH carrying a radio resource control (RRC) activation command in the first slot, the RRC activation command indicating a switch to a target TCI state; waiting until an end of a switching period triggered by the RRC activation command to use the target TCI state, the switching period being based on a RRC processing delay; and receiving, based on the end of the switching period, a second downlink channel based on the target TCI state in a second slot.

Mechanism and signaling on coreset and PUCCH resource grouping for multi-TRP operation

Methods, apparatuses, and systems are disclosed for configuring measurement timings in connection with UEs that are capable of signaling whether a measurement gap (MG) is needed to measure a target frequency carrier. For example, a measurement period may be determined for the target frequency carrier based on the UE indicating that it supports per-frequency range (FR) MGs, and determining that the FR of the target frequency carrier does not include any current serving cell(s). If the UE indicates that no MG is needed to measure the target frequency carrier, then the measurement period may be based on an SMTC, and may be further based on a predefined effective measurement gap repetition period (MGRP). If the UE indicates that a MG is needed, then the measurement period may be based on the SMTC, and may be further based on the effective MGRP or a per-UE MGRP.
