Abstract: A system in wireless network including an Access Point utilizing at least an unlicensed first wireless interface; a Station utilizing at least a first unlicensed wireless interface, transmitting in uplink to the AP; Said at least one STA further includes a secondary wireless interface different from the first unlicensed wireless interface, said STA is configured to, determine that transmission of a message be in a secondary wireless interface of the STA when it is utilized for Reliable and Low Latency Communication RLLC data transmission, generate a message and then transmit the message to a serving AP. Said AP is configured to, when receiving the message from the STA, determine whether information will be generated based on the message received from the STA, generate at least scheduling information and transmit the generated information to the STA.

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 preamble detection. According to an aspect, a method comprises: transmitting a message to a first terminal device connected to an access node, the message instructing the terminal device to carry out a random access procedure towards the access node; receiving a signal from the first terminal device during the random access procedure, the signal comprising a random access preamble; using the received signal as a training input in a random access preamble detection process; and using the random access preamble detection process trained with the training input in detection of a random access preamble from a second terminal device not connected to the access node.
