Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of TRP beam failure recovery. The method comprises determining a set of failed cells associated with the first device based on a beam failure detection; and generating a beam failure report indicating respective one or more failure detection resource sets associated with at least a portion of the set of failed cells. In this way, the UE may determine the information included in the BFR MAC CE in a case where the UL grant is not enough to include all the information for the failed serving cells or the BFR MAC to be transmitted on the MSG3 or MSGA in a CBRA procedure on the SpCell.

Abstract: Embodiments of the present disclosure relates to beam failure detection. According to embodiments of the present disclosure, after a serving cell is activated from a deactivated state, a terminal device monitors a beam failure on a serving beam of the serving cell. If a beam failure instance indication is received within a short period after the activation, the terminal device determines that the beam failure is detected on the serving beam. In this way, a beam failure recovery can be quicker triggered to perform candidate beam search.

Abstract: Embodiments of the present disclosure relate to acquiring a Timing Advance (TA) value. A terminal device being connected with a serving cell or a primary cell of the terminal device transmits a signal to a network device supporting a non-serving cell or a secondary cell of the terminal device, wherein a physical cell identifier (PCI) of the non-serving cell is different from a PCI of the serving cell. The terminal device starts, based on the transmission of the signal, a timer at the terminal device. The terminal device acquires, while the timer is running, a timing advance (TA) value associated with the non-serving cell or the secondary cell.
