Abstract
A method and an access node of a wireless network, for controlling uplink transmissions from wireless devices. It is detected that both a Narrow Band wireless device capable of receiving signals on a first narrow bandwidth channel and one or more legacy wireless devices capable of receiving signals on a second broad bandwidth channel are present. The second broad channel covers the first narrow channel. When receiving an uplink transmission from the Narrow Band device that indicates pending uplink data, the access node performs a downlink transmission that both Narrow Band wireless devices and legacy wireless devices can receive and decode. The downlink transmission indicates that the Narrow Band wireless device is allowed to transmit its pending uplink data on allocated resources within the first bandwidth channel, and that the second bandwidth channel is occupied.
