Abstract: There is provided a method, computer program, and for an apparatus for causing an apparatus for a user equipment to perform: receiving, a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, an indication of when the first timing advance value will be invalid; using the indication of when the first timing advance value will be invalid to determine that the first timing advance value is or will soon be invalid; and determining whether to autonomously initiate obtaining a second timing advance value for the target cell in dependence on the determination of whether the first timing advance value is or will soon be invalid, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: A method includes receiving, by a user equipment (UE) connected to a first cell, an activation for a first transmission configuration indicator (TCI) state of a first configured TCI state pool associated with a second cell and further receiving a configuration of a second TCI state of a second TCI state pool associated with the second cell. The UE determines that the first activated TCI state and the second TCI state share one or more properties, and based upon the determining, activates the second TCI state of the second cell. The UE performs a cell switch to the second cell, maintaining the activated second TCI state of the second cell.

Abstract: An apparatus including at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to: receive, from a network node, an indication to monitor a possibility of configuring a user equipment for single transmission reception point operation, or receive, from the network node, an indication to monitor a possibility of configuring the user equipment for multiple transmission reception point operation; determine whether it is possible to configure the user equipment for single transmission reception point operation or multiple transmission reception point operation; and transmit, to the network node, an indication that it is possible to configure the user equipment for single transmission reception point operation or multiple transmission reception point operation.

Abstract: There is provided a method, computer program, and apparatus for causing an apparatus for a first access node to perform: establishing a connection towards a user equipment via a serving cell supported by the first access node; instructing the user equipment to obtain a first timing advance value for a target cell supported by a second access node, wherein the first timing advance value indicates a timing for transmitting uplink transmissions to the target cell; receiving, from the user equipment, an indication that the first timing advance value is or will soon be invalid; and determining whether to instruct the user equipment to obtain a second timing advance value for the target cell in dependence on the received indication, the second timing advance value being obtained later in time than the first timing advance value.

Abstract: Systems, methods, apparatuses, and computer program products for supporting periodic and SP reporting on PUCCH. One method may include a UE receiving, from a network entity, at least one LTM CSI reporting configuration via radio resource configuration; receiving, from the network entity, at least one control message configured to activate or deactivate at least one of the at least one LTM CSI reporting configuration, and transmitting, to the network entity, L1 measurement reporting according to at least one of the at least one control message.

Abstract: A user equipment (UE) may receive, from a network entity, a configuration of one or more candidate cells for switching to from a serving cell. The UE may receive, from the network entity, an indication to deactivate all transmission configuration indicator (TCI) states associated with one or more indicated cells. The UE may deactivate the all TCI states associated with the one or more indicated cells based at least in part on receiving the indication to deactivate the all TCI states. One or more of the one or more candidate cells or the serving cell may include the one or more indicated cells.

Abstract: A method including: connecting, with an apparatus, to a target cell; starting a timer associated with one or more transmission configuration indicator states; determining that the one or more transmission configuration indicator states were active prior to connecting to the target cell; and based upon the timer running, considering the one or more transmission configuration indicator states as being active for at least one of a lower layer mobility or for intra/inter cell beam management within the target cell.

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.
