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: 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.

Abstract: Disclosed are methods, systems, apparatus, and computer programs for a coordination mechanism between a network and a user equipment (UE) that is configured to perform cross-link interference (CLI) measurements. In one aspect, a method includes generating a message that indicates a capability of a user equipment (UE) whether to support simultaneous reception of at least one signal associated with cross-link interference (CLI) measurement and at least one signal associated with a serving cell or a neighbor cell of the UE. The method further includes transmitting the message to an access node (AN).

Abstract: Systems, apparatuses, methods, and computer-readable media are provided for facilitating handoff of a User Equipment, engaged in beamforming, by communicating beam information between a first access point (AP) to a second AP. The first AP associated with a serving cell of the UE includes processor circuitry and interface circuitry. The processor circuitry is configured to determine that the UE device is expected to associate with the second AP and identify a synchronization signal block (SSB) index associated with the first AP. The processor circuitry is further configured to generate a message that includes the SSB index to enable the second AP to pre-configure downlink and uplink resources for the UE before the UE associates with the second AP. The interface circuitry is coupled to the processor circuitry and configured to communicate the message to the second AP.
