Patent number: 9439209Abstract: In response to determining that a time to a periodic transmission opportunity exceeds a threshold, a UE selects between using a random access procedure and the periodic transmission opportunity to transmit an uplink message. In non-limiting examples given the periodic transmission opportunity is a scheduling request opportunity which is periodic according to an interval configured by a wireless network and the uplink message comprises a scheduling request. In an embodiment the user equipment's determination and selection is conditional on it pre-determining that intended uplink data or control signaling to which the scheduling request relates is delay sensitive. If that pre-determination is that the data/signaling is not delay sensitive then it uses the scheduling request opportunity to send its scheduling request without selecting between the random access procedure and the scheduling request opportunity.Type: GrantFiled: September 30, 2011Date of Patent: September 6, 2016Assignee: Nokia Technologies OyInventors: Juha S.
