Abstract: A client device is configured to receive an indication of a first network SINR for a first data transmission from a network node, and to derive the first network SINR based on the indication of a first network SINR. The client device is further configured to estimate a SINR adjustment for a second data transmission from the network node, and to compute a SINR difference value between the first network SINR and the SINR adjustment. Furthermore, the client device is configured to transmit at least one first control message having an indication of the SINR adjustment to the network node if the SINR difference value is larger than a threshold value.

Abstract: The embodiments of the present invention relates to a first communication device, a second communication device, and a control device. According to the embodiments of the present invention beacon signals are broadcasted by first communication devices in a wireless communication system. The broadcasted beacon signals are used for calculation of received power or pathloss by second communication devices. The calculated received power or pathloss is used for estimating interference in the wireless communication system by control devices. Furthermore, the embodiments of the present invention also relates to corresponding methods, a computer program, and a computer program product.

Abstract: The application relates to beam management for a client device in a power saving state. When the client device is in the power saving state, the client device monitors serving beams of a network access node based on a serving beam configuration. The serving beam configuration indicated the serving beams to be monitored by the client device in the power saving state. If the client device detects a beam failure during the serving beam monitoring in the power saving state, the client device performs a beam reconfiguration procedure. The beam reconfiguration procedure informs the network access node about the change in serving beam status and allows the network access node to update the serving beam configuration.

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: Implementations describe a user equipment, an access node, and to methods for a user equipment and for an access node. The user equipment includes a receiver configured to receive a downlink control signal (CTRLS) over a downlink control channel (PDCCH) from an access node. The user device also includes a processor configured to, when the user equipment is in a Radio Resource Control (RRC) connected mode, switch on the receiver at a time point (tstart_symbol) when a symbol comprising the downlink control signal (CTRLS) starts in time domain. The processor is further configured to switch off the receiver at a time point (tend_symbol) when the symbol comprising the downlink control channel (CTRLS) ends in time domain.

Abstract: Device, method and computer program to make better use of measurements of received signals for determining location are provided. A client device is configured to receive a signal that contains a reference symbol modulated onto a plurality of subcarriers. The client device determines a plurality of weights based on the reference symbol and line-of-sight channel frequency responses for the subcarriers, so that each of the plurality of weights is associated with one of the subcarriers. The client device determines a gain associated with the received signal using the plurality of weights. A network device may receive from the client device information indicative of gains, wherein a gain indicates a signal strength at which the client device was able to receive a respective signal. The location of the client device may be determined by using information about network device locations, transmission directions, and the gains.

Abstract: A computing apparatus configured to communicate with nodes of a wireless communication system. The computing apparatus includes a processor configured to receive a radio link measurement corresponding to a user node. The processor determines a physical disturbance based on the radio link measurement and determines an at risk user node and a time at which the at risk user node is likely to experience a radio link disturbance, based on the physical disturbance. The processor then determines a connectivity adjustment for the at risk user node, and sends the determined connectivity adjustment to the wireless communication system.

Abstract: An access node in a wireless communication system includes a transceiver configured to receive one or more uplink pilots associated with a user node via a radio link, and a processor configured to determine, based on the one or more uplink pilots, a location of the user node and whether the radio link is a line of sight radio link or a non-line of sight radio link. When the radio link is a line of sight radio link, the processor determines a position based precoding vector based on the location of the user node, and generates a precoded downlink control signal based on the determined position based precoding vector. The transceiver transmits the precoded downlink control signal to the user node.
