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.

20140321404 | Fixed HS-DSCH or E-DCH Allocation For VOIP (Or HS-DSCH Without HS-SCCH/E-DCH Without E-DPCCH) - In order to reduce the HS-SCCH overhead, a fixed time allocation approach could be used.
