Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable storage media of communication for BFR. A method implemented at a first device comprises detecting a beam failure for a serving cell of the first device; in accordance with a determination that the beam failure is detected for the serving cell, triggering a procedure for a beam failure recovery for the serving cell; determining whether information related to the beam failure recovery is available for the serving cell; and in accordance with a determination that the information is unavailable, transmitting to a second device a first indication that the beam failure is detected and a second indication that no candidate beam is available. In this way, the full BFR information for the failed serving cells can be acquired finally, and more reliable and faster BFR can be achieved.

Abstract: A method may include measuring, by a user device in a wireless network, a plurality of downlink reference signals received from a network node, wherein the plurality of downlink reference signals are associated with a group of transmission configuration indication (TCI) states that may be used at least for uplink communication by the user device; determining, by the user device based at least on the measuring, a plurality of subsets of the downlink reference signals, wherein the TCI states associated with any one subset of the plurality of subsets of downlink reference signals may be activated at a time by the user device for uplink transmission; and sending, by the user device to the network node, a measurement report that indicates one or more downlink reference signals for each subset of the plurality of subsets.

Abstract: Example embodiments relate to wireless communication devices, methods and systems for beam failure recovery (BFR) in a cell activation procedure. According to an embodiment, a method for cell activation includes receiving, at a terminal device (UE), a first indication from a network to activate a cell configured for the UE, and responsive to the first indication, triggering a beam information reporting for the cell.

Abstract: An apparatus for a terminal has means for storing a first configuration for measurement reporting on downlink reference signals, wherein one or more downlink reference signals correspond to one of a plurality of states for a first channel. The apparatus also has means for receiving an activation of a first state of the plurality of states for the first channel, and determining a second configuration for measurement reporting based on the first configuration for measurement reporting and the received activation of the first state, wherein the second configuration for measurement reporting configures the terminal to report measurements on a first downlink reference signal corresponding to the first state.

Abstract: Systems, methods, apparatuses, and computer program products for supporting a narrow serving beam in a hierarchical beam configuration. For example, certain embodiments may provide a UE that may receive, from a network node, information of a quasi co-location (QCL) configuration of self-contained, aperiodic, and/or semi-persistent tracking reference signals (TRSs) for sub-beams, where a source for one or more TRSs may be channel state information (CSI-RS) without repetition. In addition, the UE may determine these TRSs as self-contained, for which there are no associated periodic TRSs, if there is a TRS configured for an SSB sub-beam.

Abstract: Embodiments of the present disclosure relate to failure recovery for serving cell. A terminal device detects a failure on a serving cell of the terminal device. If the beam failure is detected, the terminal device transmits information concerning the detected failure to a network device. The network device is associated with the serving cell. The terminal device disables further transmission of the information to the network device.

Abstract: The method includes performing at least one first monitoring of a power savings channel of a physical downlink control channel (PDCCH) for control information, the PDCCH being associated with at least one base station, the control information including a power saving downlink control information (PS-DCI) format, the control information providing an indication to start a timer for an ON duration of a discontinuous reception (DRX) cycle for a user equipment (UE) to monitor the PDCCH. The method further includes performing a random-access channel (RACH) procedure with the at least one base station based on the control information. The network node performs the method.

Abstract: A method of beam failure recovery for a serving cell is disclosed. In response to a beam failure on a first bandwidth part in a serving cell, a first device detects a first candidate beam associated with the first bandwidth part (310). In response to a failure of detecting the first candidate beam, the first device switches from the first bandwidth part to a second bandwidth part in the serving cell. The second bandwidth part is configured with at least one reference signal identifying a second candidate beam for recovery from the beam failure (320). The first device detects the second candidate beam based on the at least one reference signal (330). In response to a success of detecting the second candidate beam, the first device transmits information concerning the second candidate beam to a second device for the recovery from the beam failure (340).
