    Abstract: Exemplary embodiments of the present disclosure relate to a beam failure recovery to a cell. In an aspect, a first network device determines a radio resource control (RRC) reconfiguration for one or more cells prepared by the first network device. The RRC reconfiguration comprises a beam failure recovery configuration to be used by a terminal device for performing a beam failure recovery to the one or more cells. The first network device transmits, to a second network device, the RRC reconfiguration. By this process, the UE may recover to a non-serving cell in case of detecting a beam failure.

    Abstract: Embodiments of the present disclosure relate to lower layer triggered mobility. In an aspect, a terminal device receives a radio resource control signaling including a transmission configuration indicator from a first network device. The transmission configuration indicator state is configured for beam-only-switching. The terminal device performs beam-only switching based on the transmission configuration indicator state and a first switching command, then configuration switching based on the first switching command or a second switching command. As such, a solution for enhanced lower layer triggered mobility is provided, thereby reducing the interruption time.

    Abstract: Described herein is a user equipment, UE, configured to establish a connection towards a first network node (e.g. source DU) via a first cell supported by the first network node (source DU). The UE receives configuration information related to performing measurements for a target cell as candidate cell for a cell change, wherein the target cell is supported by a second network node (target DU), and determines further configuration information related to monitoring validity of a timing advance value related to the target cell. The UE is e.g. further enabled to send towards the first network node (source DU) a first (L1) measurement report including target cell measurement info, and to receive from the first network node (source DU) an instruction to acquire timing advance value for the target cell. The UE then acquires timing advance value for target cell, and monitors the validity of acquired timing advance value based on the further configuration. The UE may then send towards the first network node (source DU) information regarding validity and/or invalidity of the timing advance value of target cell.

    Abstract: Systems, methods, apparatuses, and computer program products for time division multiplexing pattern configuration. The method may include detecting (900) a power exposure event at a user equipment. The method may also include reporting (905) the power exposure event to a network element. The method may further include receiving (910) instructions from the network element to activate a duty cycle pattern at the user equipment. In addition, the method may include activating (915) the duty cycle pattern by performing uplink transmission based on a new communication pattern.
