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

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

Approaches are described for receiving downlink signals simultaneously where analog beamforming is being used to increase the link budget between the base station and user equipment (UE). Alternatives within these approaches include the UE determining the synchronization signal block (SSB) to receive when there are multiple SSBs from different cells in a slot, and determining whether there are other signals in the same symbols with the selected SSB based on the type of signal and the SSB's functionality. In the case where there are another downlink signals channel state information-reference signal (CSI-RS) or physical downlink shared channel (PDSCH) from another cell, the UE selects the corresponding quasi co-location (QCL) assumption to receive the signals. Optionally, the UE can report whether it can support one or two QCL-TypeD at a time and whether it supports SSBs in different cells multiplexed in overlapped symbols.

Method for simultaneous reception of SSB and other signals

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 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

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

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.

CSSF design for UE with NeedForGap capability

Techniques described herein involve the use of quasi-co-location (QCL) capabilities and spatial relation assumption to enable a UE to designate a single beam for connections with a base station during a physical random access channel (PRACH) procedure. Once the PRACH procedure is complete, the beam may be reset after a pre-determined duration, which may account for decoding latency, or maintained until additional transmission configuration indication (TCI) is received. Also addressed are scenarios involving multiple transmission reception points (TRPs) and switching between beam management schemes based on one or more factors including device capabilities.

Systems, methods, and apparatuses for quasi-co-location (QCL) and spatial relation assumptions during random access procedures

The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.

Transmission of sounding reference signal (SRS) based on SRS transmit antenna port switching

A user equipment (UE) is configured to simultaneously connect to a primary cell (PCell) serving a primary component carrier (PCC), a primary secondary cell (PSCell) serving a primary secondary component carrier (PSCC) and at least one secondary cell (SCell) serving a secondary component carrier (SCC), wherein the PSCell is in a deactivated state. The UE receives a radio resource management (RRM) measurement configuration comprising a PCC measurement object (MO) configuration, a PSCC MO configuration, and an SCC MO configuration, determines a PCC MO carrier specific scaling factor (CSSF), a PSCC MO CSSF, and an SCC MO CSSF and applies each respective CSSF to a measurement period corresponding to each of the PCC MO, the PSCC MO, and the SCC MO.
