    Abstract: Embodiments of the present disclosure relate to methods and apparatus for beam maintenance in a radio access network, in particular, through random access preamble transmission for beam maintenance. A terminal device receives, from a network device, a resource configuration for contention-free random access. The resource configuration indicates a plurality of CFRA resources each associated with a respective synchronization signal and physical broadcast channel block index or channel state information reference signal index. The plurality of CFRA resources are applicable for timing advance acquiring in a target network device. The terminal device transmits, to the target network device, one or more CFRA physical random access channels based on the resource configuration. In this way, beam maintenance may be performed based on an SSB index or CSI-RS index associated with one of the transmitted CFRA PRACH(s) before a cell switch command or a random access response.

    Abstract: Systems, methods, apparatuses, and computer program products for configuration and transmission of a channel state information reference signal (CSI-RS). A method may include forwarding, to a network element, synchronization signal block measurements of a target cell along with synchronization signal block indices. The method may also include requesting the network element to provide a channel state information reference signal configuration for a channel state information reference signal index whose source reference signal corresponds to at least one of the synchronization signal block indices. The method may further include receiving the channel state information reference signal configuration from the network element. In addition, the method may include transmitting the channel state information reference signal configuration to a user equipment. Further, the method may include receiving a measurement report on the channel state information reference signal index according to the channel state information reference signal configuration.

    Abstract: Various example embodiments relate to methods, devices and systems that support early beam failure recovery. A terminal device may terminal device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the terminal device to perform actions including detecting a beam failure state in association with at least one serving beam, and determining if at least one non-serving beam better than the at least one serving beam is available. The actions may further include triggering an early beam failure recovery (BFR) procedure in a case where the beam failure state is detected and the at least one non-serving beam better than the at least one serving beam is available.

    Abstract: A terminal node for a radio network comprising means for: receiving multiple positioning reference signals transmitted from respective transmission reception points of a network; determining time of arrival of the multiple positioning reference signals received from the respective transmission reception points; measuring at least a received signal quality metric for the multiple received positioning reference signals; processing, at least the multiple respective received signal quality metrics for the multiple received positioning reference signals, to trigger a received signal quality decision; and in response to the received signal quality decision, informing the network. A node of a radio network comprising means for: enabling transmission of multiple positioning reference signals from respective transmission reception points of a network; being informed of a received signal quality decision made at the terminal node in respect of measured received signal quality metrics for the transmitted positioning reference signals received at the terminal node; and in response, causing adaptation of transmission of signals in the network.

    Abstract: The method includes receiving first configuration information from a network node, the first configuration information including information on a discontinue reception (DRX) cycle and a notification to monitor a physical downlink control channel (PDCCH) transmission carrying a wake-up indication, receiving second configuration information from the network node, the second configuration information including configuration information for secondary cells (SCells) that are associated with the network node, first determining an overlap occurrence using the DRX cycle, the overlap occurrence occurring due to one or more time occurrences overlapping with at least one first bandwidth part (BWP) active-time of an active bandwidth part (BWP) of the PDCCH, activating one more serving cells, following the determining of the overlap occurrence, and conducting an operation of data communications with the network node using the one or more serving cells that are activated. A network node is configured to perform the method.
