Abstract: A network node for a wireless communication system is configured to localize a user node in a first localization operation carried out at a first frequency; determine an accuracy value associated with the first localization operation; and adjust at least one beam parameter for radio beams to be used in a second localization operation based on the determined accuracy value, the second localization operation carried out at a second frequency that is greater than the first frequency. The network node is configured to determine the accuracy value associated with the first localization operation by tracking a rate of change of an angle of a radio beacon signal transmitted from the user node relative to the network node.

Abstract: This application provides a client device, a method, and a computer program. The client device obtains a first parameter associated with a radio link failure timer. The first parameter indicates a first time period during which the radio link failure timer is reset and thereafter started. The client device further obtains a second parameter associated with the radio link failure timer. The second parameter indicates a second time period during which the radio link failure timer is started and thereafter reset. Based on the first parameter and the second parameter, the client device determines a value of the radio link failure timer.

Abstract: The present disclosure provides an access node configured for determining at least one beamforming parameter for communication between the access node and a user node. The access node including: a first-band receiver configured to receive at least one first signal from said user node on a first frequency band; a processor and a non-transitory computer-readable medium including computer-executable instructions executed by the processor to perform, on the access node, determining at least one first beamforming parameter based on said received first signal; and a second-band transmitter configured to send, with a transmit beam that is configured based on said determined first beamforming parameter, on a second frequency band at least one second signal to said user node. The first frequency band includes lower frequencies than the second frequency band.

Abstract: Embodiments of the present disclosure disclose a command execution method and apparatus, a terminal, and a server related speech recognition and natural language processing. In the command execution method, during an interaction between a terminal and a user, a server configured to execute a user command or the terminal may store slots and GUI information corresponding to the slots. When the filling information of the slots configured for the user command is missing, the server configured to execute the user command may obtain the missing filling information of the slots from the stored GUI information, to avoid multiple interactions between the user and the terminal. The interaction between the user and the terminal is made more intelligent, thus improving command execution efficiency.

Abstract: A client device includes a processor and a memory. The client device is caused to obtain a first indication indicating an outcome of a link monitoring procedure associated with a serving link between a network access node and the client device. The client device is also caused to obtain a second indication indicating an outcome of a link re-configuration procedure associated with the serving link. The client device is further caused to determine a value of a first counter associated with a radio link failure timer based on the first indication and the second indication. The client device is additionally caused to start the radio link failure timer when the value of the first counter is equal to or larger than a first counter threshold value.

Abstract: A network node includes an antenna array having a plurality of antenna sub-arrays. A switching device is coupled to the antenna array, the switching device being configured to connect at least two input signals to respective ones of the plurality of antenna sub-arrays. A processor is configured to determine a channel capacity, wherein based on the channel capacity, the processor is configured to control the switching device to switch a connection of the at least two input signals to different ones of the plurality of antenna sub-arrays to change one or more of an inter-distance between the respective ones of the plurality of antenna sub-arrays and a down-tilting angle of the antenna array.
