Abstract: To configure a wireless sensor network, a sink node receives from nodes first reports, a first report from a node indicating quality of service requirement of the node and battery information of the node, and second reports, a second report from a node indicating at least a signal strength of one signal received from another node. The information in the first reports and in the second reports are used for determining paths from the nodes to the sink node, wherein a path of a node is either a direct link from the node to the sink node or the path comprises at least one node acting as a cluster head between the node and the sink node.

Abstract: The present subject matter relates to a method comprising: determining that a communication of data in a cyber-physical system may not fulfil an availability criterion. An emergency schedule of resources may be determined for enabling a communication of further data in the system in compliance with the availability criterion. The emergency schedule of resources may be used for communication of further data in the system in case the communication of the data does not fulfill the availability criterion.

Abstract: Example embodiments of the present disclosure relate to handover of subnetworks. The first apparatus determines that a first subnetwork is triggered to handover from a first cell to a second cell, the first apparatus being in the first subnetwork; based on the triggering, communicates with at least one other apparatus in the first subnetwork by using a first frequency resource; receives, from a second apparatus providing the second cell, resource configuration indicating a second frequency resource to be used in the first subnetwork instead of the first frequency resource; and communicates with the at least one other apparatus by using the second frequency resource indicated in the resource configuration.

Abstract: An apparatus, and method relating to control of radio repeaters is disclosed. The apparatus may comprise a means for transmitting one or more reference signals at a transmit power level using a transmit antenna of a repeater. The apparatus may also comprise a means for measuring a receive power level of the corresponding one or more reference signals received using a receive antenna of the repeater and determining a selfinterference power value based on the difference between the transmit power level of the one or more reference signals and the receive power level of the one or more corresponding reference signals. The apparatus may modify a gain associated with an amplifying means of the repeater based on the determined self-interference value.

Abstract: This document discloses a solution for performing anti-jamming procedures. According to an aspect, a method for a terminal device comprises: receiving a first reference signal allocation from an access node, wherein the first reference signal is unique to the terminal device in a cell managed by the access node; receiving a second reference signal allocation from the access node, wherein the second reference signal is shared with at least one other terminal device in the cell; causing transmission of payload data together with the first reference signal according to a regular transmission pattern; and breaking the regular transmission pattern by transmitting dummy data together with the second reference signal in a time-frequency resource shared with the at least one other terminal device.

Abstract: A method includes detecting (205), in a first communications apparatus, the number of failed code blocks in a transport block transmitted to the first apparatus from a second apparatus and a corresponding feedback size indicator. The feedback size indicator is received in the first apparatus from the second apparatus e.g. via control channel signalling. Alternatively, the feedback size indicator is received in the transport block. The first apparatus selects the format of a HARQ feedback message to be generated based on the feedback size indicator, and generates the feedback message based on the number of failed code blocks in the transport block. The generated feedback message is of the selected format and indicates the failed code blocks in the transport block. The first apparatus transmits the generated feed back message to the second apparatus.
