Abstract: Various example embodiments relate to apparatuses and methods for inter-cell beam management. An apparatus may be configured to support a first control resource set and a second control resource set for a serving cell, receive a transmission configuration indicator state indication for the first control resource set for a cell other than the serving cell, and ignore, for the second control resource set, the received transmission configuration indicator state indication when the second control resource set is configured to follow a transmission configuration indicator state indication for the serving cell.

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: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

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: Embodiments of the present disclosure relate to methods and apparatuses for sounding reference signal transmission. According to some embodiments, an apparatus is caused at least to: receive, from a network device sounding reference signal (SRS) configuration comprising one or more SRS resource sets; receive, from the network device, a message comprising an indication of which one of the one or more SRS resource sets is configured or enabled to follow or not follow corresponding one or more indicated transmission configuration indication (TCI) states from an activated TCI list for the apparatus; and transmit, to the network device, an SRS based on the indication. In this way, SRS resource sets may be dynamically detached to not follow specific TCI state and used for sounding the uplink channel in an efficient manner.
