Abstract: A method is provided for handling resources for uplink semi-persistent scheduling transmission, wherein the resources are reserved periodically for a specific service, the method including monitoring data transmitted on the semi-persistent scheduling reserved resources and dynamic scheduled resource, checking whether a specific data element related to the specific service has not been received consecutively for a predefined period on the semi-persistent scheduling reserved resources and dynamic scheduled resource, and determining, when the specific data element has not been received for the predefined period, that the use of the specific service has ended. When it is determined that the use of the specific service has ended, an explicit release for the semi-persistent scheduling reserved resources may be triggered.
