Abstract: Inter-cell mobility may include decoding a first radio resource control (RRC) reconfiguration message received from a first cell. The first RRC reconfiguration message may comprise a first portion of configuration information for performing a cell change to a second cell. A cell change message received from the first cell may be decoded. The cell change message may indicate that a cell change to the second cell is to be performed. A cell change acknowledgment may be encoded for transmission to the second cell. A second RRC reconfiguration message received from the second cell may be decoded. The second RRC reconfiguration message may comprise a second portion of configuration information for performing the cell change to the second cell. The second portion of configuration information may comprise a remaining portion of configuration information to perform the cell change to the second cell.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to perform a switch of a TCI state from a serving cell to a neighbor cell. A UE determines whether the state of the neighbor cell is known or unknown and whether the neighbor cell’s TCI state is known or unknown. The total delay time to perform the TCI state switch can impacted by this the known/unknown statuses. Other factors can also contribute to the total delay time. The UE may also signal its capability to monitor the TCI state of the neighbor cell and its capability to switch to such a TCI state.

Abstract: Methods and apparatus provide for a wireless network to enable multiple-transmission reception point (multi-TRP) uplink (UL) time division multiplexed (TDMed) repetition transmission. The network may receive, from a user equipment (UE), beam measurements of downlink reference signals associated with a plurality of UL transmission beams from the UE to the multi-TRP. Based on criteria associated with the beam measurements received from the UE, the network enables the UE for the multi-TRP UL TDMed repetition transmission using the plurality of UL transmission beams. In addition, or in other scenarios, coordination is provided between the network and the UE to improve UL TDMed repetition transmissions when a UE switches between antenna panels.

Abstract: Methods, systems, and storage media are described for the Embodiments discussed herein may relate to enhancements to radio link monitoring (RLM) for new radio (NR) systems. A user equipment (UE) may be configured to retrieve configuration information from a memory. The UE may further determine, based on the configuration information, that a radio link monitoring-reference signal (RLM-RS) resource is configured for quasi co-location (QCL) Type D with more than one control resource set (CORESET), and determine, based on the RLM-RS resource being configured for QCL Type D with more than one CORESET, a physical downlink control channel (PDCCH) parameter for radio link monitoring (RLM). Other embodiments may be described and/or claimed.

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: Systems and methods provide Layer 1 reference signal received power (L1-RSRP) measurement and transmission configuration indication (TCI) state switching. A cellular communications network determines a plurality transmission reception points (TRPs) configured for high speed train (HST) communication using millimeter wave (mmWave) signals, and generates a synchronization signal block (SSB) index configuration for the plurality TRPs. The SSB index configuration uses non-adjacent SSB indexes between the plurality of TRPs. A user equipment (UE), in response to entering a HST mode, performs L1-RSRP measurement sharing for SSBs received from different TRPs. A scheduling restraint may be used for TCI state switching. Autonomous UL TA adjustment timing may also be used.

Abstract: A user equipment (UE) is configured to communicate with a base station using a set of component carriers (CCs) configured for a carrier aggregation (CA) mode, in accord with a first common transmission configuration indication (TCI) identifier (ID) applied to the set of CCs. The UE is also configured to receive, from the base station, a command to switch from applying a first common TCI ID to the set of CCs to applying a second common TCI ID to the set of CCs; transmit, to the base station, an acknowledgement of the command to apply the second common TCI ID to the set of CCs; and transmit data to or receive data from the base station, using the set of CCs and in accord with the second common TCI ID, after an action delay including a first time period in which the acknowledgement is transmitted. The first time period is based on a smallest subcarrier spacing of the set of CCs.

Abstract: Apparatuses, systems, and methods for mitigation of listen before talk conflicts in the unlicensed spectrum. A wireless device may receive one or more synchronization signal blocks (SSBs) from a base station (BS) as part of a measurement procedure with listen before talk (LBT). The wireless device may determine one or more LBT failures associated with one or more receive beams of the wireless device. Furthermore, in response to determining the one or more LBT failures associated with the one or more receive beams of the wireless device, the wireless device may extend a measurement period for the one or more receive beams of the wireless device. The wireless device may then receive one or more additional SSBs on the one or more receive beams of the wireless device.
