Abstract: An apparatus and computer program are disclosed. The apparatus has at least one processor and at least one memory including computer program code. The at least one memory and computer program code being configured to, with the at least one processor, cause the apparatus to receive a plurality of coordination requests from a plurality of user equipment. The coordination requests include a request for information on resources for use for direct inter-user equipment transmissions and include an indication of a preference of resources for receiving a coordination response.

Abstract: An apparatus, method and computer program are provided that relates to determining that a condition indicating that at least one first user equipment needs a sidelink communication with a second user equipment is met; and determining to use a first discovery model including broadcasting a discovery announcement to the at least one first user equipment.

Abstract: An intermediate apparatus and method for relaying data from a remote wireless device to a base station with reduced latency is discussed. The method includes the steps of receiving a transmission having control information and data. Determining from the control information that the data is to be forwarded to a wireless communication node and that a future data transmission comprising data to be forwarded is scheduled. Estimating from the control information an amount of the data in the future data transmission. Generating a resource request comprising the estimated amount of data in the future data transmission and transmitting, the resource request towards the wireless communication node.

Abstract: The disclosure relates to an apparatus comprising: means for determining (600) that a condition indicating that at least one first user equipment needs a sidelink communication with a second user equipment is met; and means for determining (602) to use a first discovery model including broadcasting a discovery announcement to the at least one first user equipment.
