Abstract: A user equipment (UE) is configured to simultaneously connect to a primary cell (PCell) and a primary secondary cell (PSCell) of a wireless network, wherein a primary component carrier (PCC) of the PCell and a primary secondary component carrier (PSCC) of the PSCell are both in frequency range 1 (FR1). The UE receives a PCC measurement object (MO) configuration, a PSCC MO configuration, and an inter-frequency MO with no measurement gap configuration, determines a PCC MO carrier specific scaling factor (CSSF), a PSCC MO CSSF, and an inter-frequency MO with no measurement gap CSSF and applies each respective CSSF to a measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap to determine a scaled measurement period corresponding to each of the PCC MO, the PSCC MO, and the inter-frequency MO with no measurement gap.

Abstract: A user equipment (UE) may support concurrent synchronization signal block (SSB) inter-frequency measurement without a measurement gap (MG). The UE may also, or alternatively, support concurrent SSB inter-frequency measurement in intra-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band) and/or inter-band scenarios (e.g., where a target inter-frequency cell and serving cell are on the same band). The UE may report concurrent SSB based inter-frequency measurement as a NEEDFORGAP information element (IE), which may include one or more of a variety of parameters regarding UE measurement capabilities. Scheduling restrictions (e.g., restrictions to downlink and uplink communications) are also enabled based on UE measurement capabilities, including scheduling restriction for frequency range 1 (FR1), frequency range 2 (FR2), and cross frequency range scenarios.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc.) can operate to configure a hand over (HO) or a primary secondary cell (PSCell) addition based on a channel state information reference signal (CSI-RS) based contention free random access (CFRA) procedure. A CSI-RS rough timing of a CSI-RS position can be determined based on a synchronization signal block (SSB) associated with a CSI-RS or a serving cell timing. A CFRA transmit timing can be determined based on the CSI-RS rough timing or a CSI-RS fine timing that is derived from a timing and frequency (T/F) tracking operation on the CSI-RS. Reference signal receive power (RSRP) measurement(s) can be made on the CSI-RS for performing the CSI-RS based CFRA procedure with transmissions according to the CSI-RS transmit timing of the CSI-RS that satisfies an RSRP threshold.

Abstract: Apparatuses, systems, and methods for performing dual active protocol stack handovers in a frequency range above 24 GHz. A UE may transmit an indication to a base station indicating a dual active protocol stack (DAPS) handover capability of the UE corresponding to a frequency range (FR) above 24 GHz. The UE may receive, from a target cell of the one or more cells, a command to perform a DAPS handover from a source cell to the target cell. While performing the DAPS handover and maintaining a data connection with the source cell, the UE may perform measurements on the target cell followed by a physical random access channel (PRACH) procedure. The UE may then receive a source cell release command from the target cell and release the data connection with the source cell.

Abstract: Apparatuses, systems, and methods for determining timing advance in L1/L2 inter-cell mobility. A user equipment (UE) comprises at least one antenna, at least one radio coupled to the at least one antenna, and a processor coupled to the at least one radio. The processor is configured to receive a Time advance (TA) indicator together with a handover command from a source base station in a source coverage, wherein the TA indicator comprises information for determining a TA used for an uplink transmission with a target base station in a target coverage, the handover command is a Layer 1 handover command or a Layer 2 handover command, and the source coverage and the target coverage are identified by different Physical Cell identifiers; and in response to the handover command, determine the TA used for the uplink transmission with the target base station based on the information.

Abstract: This disclosure provides details of sequence-based WUS design and signaling, also DCI-based WUS design which also serves as scheduling DCI. For sequence-based WUS there are two variants. A first is based on CSI-RS, that is relatively wide band so the sequence occupies wider band compared to SSB transmission. The second is more akin to the Secondary Synchronization Signal (SSS) type of sequence in that it occupies a narrower band over the entire bandwidth.
