The present application discloses how to detect collisions between scheduling assignment transmissions from two terminal devices (100A, 0B) that are configured for device-to-device communication.

Abstract: The present disclosure relates to transmitting assistance information from a first node to a second node. In one embodiment, a first node includes a wireless transmitter and a wireless receiver. In response to transmitting a preference indicator for a first configuration to a second node via the wireless transmitter or receiving a reconfiguration request associated with the preference indicator for the first configuration, the first node starts a timer set to a value that defines an amount of time before the first node is permitted to transmit a preference indicator for a second configuration to the second node. The first node then blocks transmission of the preference indicator for the second configuration to the second node until the timer has expired. In this manner, excessive signaling of preference indicators from the first node to the second node is avoided.
