  • TRANSMITTING NODE, RECEIVING NODE AND METHODS PERFORMED THEREIN
    Publication number: 20240340661
    Abstract: Embodiments herein may for example disclose a method performed by a transmitting node, such as a first network node, for handling communication between a control node and a device controlled by the control node. The control node and the device are configured for wired communication. The transmitting node receives one or more packets in a first format from the control node or the device over a wired connection. The transmitting node processes the one or more packets into a second format for communication over a wireless connection by using a transmission process for processing the one or more packets into the second format; and transmits the one or more packets in the second format over the wireless connection towards the device or the control node.

    Abstract: Network equipment (20) is configured for use in a wireless communication network (10). The network equipment (20) determines an inter-network interference condition (50C) measured by a set of sensors (30) deployed in a coverage area of the wireless communication network (10). The inter-network interference condition (50C) characterizes interference to the wireless communication network (10) from one or more other wireless communication networks (50). Based on the determined inter-network interference condition (50C), the network equipment (20) adapts time division duplexing, TDD, configuration (14) of one or more radio network nodes (12) in the wireless communication network (10).

  • User equipment based packet data convergence protocol (PDCP) duplication activation and deactivation
    Patent number: 12041487
    Abstract: A process for execution by user equipment (UE) for activation or deactivation of a Radio Link Control (RLC) entity for Packet Data Convergence Protocol (PDCP) duplication includes identifying a set of RLC entities that are configured by a Radio Resource Control (RRC) for communication using PDCP. The process includes, for each RLC entity of the set of RLC entities: determining a network configured offset value; determining a channel condition value; and determining an RLC entity level value based on a combination of the network configured offset value and the channel condition value. The process includes comparing the RLC entity level value for each RLC entity to a threshold value; and based on comparing the RLC entity level value to the threshold value, selecting a subset of RLC entities for PDCP duplication; and activating or deactivating PDCP duplication for the selected subset of RLC entities.

  • Controlling Transmission on a Resource Subject to a Listen-Before-Talk Procedure
    Publication number: 20240155390
    Abstract: Wireless communication equipment (18) is configured for use in a wireless communication network (10). As listen-before-talk, LBT, attempts occur over time on a transmission resource (16-1 . . . 16-N), the wireless communication equipment (18) makes updates to a performance rating (22-1 . . . 22-N) for the transmission resource (16-1 . . . 16-N) to reflect an observed likelihood of LBT pot attempt success or failure on the transmission resource (16-1 . . . 16-N). Responsive to a failed LBT attempt on the transmission resource (16-1 . . . 16-N) occurring unexpectedly according to the performance rating (22-1 . . . 22-N), the wireless communication equipment (18) applies a bias (26-n) to the performance rating (22-1 . . . 22-N) to reflect a greater likelihood of LBT attempt failure, or a smaller likelihood of LBT attempt success, than actually observed on the transmission resource (16-1 . . . 16-N), and relaxes the applied bias (26-n) over time.

A batch of redundant PDUs is transmitted from the transmitter (100) to the receiver (200). A number of the redundant PDUs per batch depends on the control command for the reliability and a temporal spread of the redundant PDUs per batch depends on the control command for the latency.
