摘要： 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.

摘要： 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.

摘要： 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.

摘要： According to one example embodiment, a method may include receiving, by a user equipment, at least one network entity failure indication configuration. The method may further include detecting, by the user equipment, that at least one first network entity satisfies at least one beam-failure condition. The method may further include selecting, by the user equipment, one or more of at least one resource and at least one parameter based on the at least one received network entity failure indication configuration. The method may further include transmitting, by the user equipment, the at least one indication of the at least one first network entity that satisfies the at least one beam-failure condition to at least one second network entity.

摘要： Systems, methods, apparatuses, and computer program products for beam group-based downlink transmit beam indication. Certain embodiments may provide enhancements related to physical layer design for multiple input multiple output and/or enhancements for a beam indication framework for scenarios with multiple transmission reception points and user equipment equipped with multiple antenna panels. A network node may transmit, and a user equipment may obtain, information indicating that one or more activated transmission configuration indictor states are associated with a set of beam groups.

摘要： According to a first embodiment, an apparatus may include at least one processor and at least one memory including computer program code. The at least one memory and the computer program code can be configured to, with the at least one processor, cause the apparatus to at least determine at least one reference value configured to evaluate at least one beam change condition based on at least one measurement. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least determine whether at least one beam has changed. The at least one memory and the computer program code can be further configured to, with the at least one processor, cause the apparatus to at least, upon determining that the at least one timer T has expired, determine that the at least one beam change condition has been fulfilled.
