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: Techniques, described herein, include solutions for enabling power control processes within a wireless telecommunications network. A base station may operate in a full duplex mode by simultaneously sending and receiving signals to user equipment (UEs). Power control processes may be implemented to eliminate or mitigate signal interference, such as self-interference at the base station or cross link interference (CLI) at a UE. The power control processes may include causing UEs to transmit signals, a UE and/or the base station measuring interference and causing the base station and/or UEs to modify transmission power to address the signal interference.

Abstract: Techniques, described herein, include solutions for enabling a user equipment (UEs) to operate in a power saving mode (PSM) by performing radio link monitoring (RLM), beam failure detection (BFD), and radio resource management (RRM) based on one or more reference signals with a decreased periodicity. The reference signals may include system synchronizations blocks (SSBs), a channel state information (CSI) m signal (CSI-RSs), or a combination thereof. A base station may be configured to operate as a master cell group (MCG) node or a secondary cell group (SCG) node and may transmit reference signals with an increased periodicity to UEs in an active mode of operation while also transmitting reference signals with a decreased periodicity to UEs in a PSM.

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.
