Methods, apparatuses and computer programs for configuring uplink transmissions of one or more wireless devices

Abstract

Addressing issues to provide a system wide effective support of ambient IoT (AIoT) devices. It is likely that the allocated radio resources for wireless device communication (e.g. AIoT communication) will be limited and means of efficient control of the radio resource access is needed. Furthermore, as some wireless devices (AIoT devices) will need a carrier wave from a Reader to transmit uplink data, there will be a need to limit the time that such carrier wave is transmitted. It is important a Reader can trigger several wireless devices in an efficient way while enabling those wireless devices to transmit uplink data and minimise collisions. Configuring uplink transmission of one or more wireless devices by a first network node is provided. Configuring uplink transmission of one or more wireless devices by a first network node comprises receiving from a second network node a trigger request to trigger one or more wireless devices to perform an uplink transmission; and generating a trigger message based on the trigger request, the trigger message including identification information identifying the one or more wireless devices and configuration information indicating a resource for uplink transmission for the one or more wireless devices.
