Abstract: Disclosed is a method comprising detecting a beam failure on at least one transmission reception point of a plurality of transmission reception points. One or more beam failure indication data is included into a first medium access control (MAC) control element (CE), wherein the one or more beam failure indication data indicates the beam failure detected on the at least one transmission reception point. The one or more beam failure indication data comprises at least a first bit that comprises a first value and a second value, wherein the first value of the first bit indicates a first transmission reception point at least on which the beam failure is detected. The first MAC CE comprising the one or more beam failure indication data is transmitted to an access point.

Abstract: The present disclosure relates generally to the field of wireless communications, and particularly to a technique for performing the beam failure recovery (BFR) of transmission reception points (TRPs) in a multiple-TRP (mTRP) scenario. More specifically, the technique involves defining rules according to which a UE may determine that the TRPs have failed concurrently or the TRPs are considered to fail individually in the mTRP scenario. Such rules are defined based on current counter values of beam failure instance (BFI) counters used by the UE for each of the TRPs. In some embodiments, the rules may be additionally defined based on current timer statuses of timers supervising the BFI counters. By using the rules thus defined, it is possible for the UE to clearly determine when it is required to use the BFR mechanism individually for at least one of the TRPs or concurrently for all the TRPs in one or more cells.

Abstract: Systems, methods, apparatuses, and computer program products for beam failure detection and/or beam failure recovery procedures, for instance, for multi-panel user equipment (UEs) are provided. One method may include transmitting, by a UE, a beam report to a network to indicate an association between at least two downlink reference signals and at least two antenna panels at the user equipment or to indicate a selection of at least two downlink reference signals that will be used for downlink reception at the user equipment simultaneously. The method may also include activating the antenna panels corresponding to one or more of the at least two downlink reference signals, based on transmission configuration indicator (TCI) states updated by the network or based on the selection of the at least two downlink reference signals, and detecting beam failure based on at least two sets of beam failure detection resources for the active antenna panels.

Abstract: Methods, apparatuses, and computer program products are described that support operational mode configurations for switching between serving cells. A serving cell may configure a plurality of cells to support the operational mode configuration. Each cell of the plurality of cells and an associated user equipment may store the operational mode configurations associated with the plurality of cells to improve additional switching between serving cells. A user equipment may provide intracell or intercell beam management reporting associated with the plurality of cells to assist a determination for switching between serving cells. Timing advance information may be stored to support switching back to a serving cell. A serving cell may cause switching to another serving cell for a user equipment.
