Selection between random access and dedicated scheduling request resources

摘要

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.

主权项

1. An apparatus comprising:
at least one processor; and at least one memory including computer program code, in which the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to: determine that a time to a periodic transmission opportunity exceeds a threshold; and in response to the determining, select between using a random access procedure and the periodic transmission opportunity to transmit an uplink message, in which the threshold is configured by a wireless network and the threshold is radio bearer specific.
