1. A method performed by a network node of a wireless communications network, the method comprising:

  • receiving, from a first user equipment (UE), a request to perform an inter-device session (IDS) between the first UE and a second UE;

    determining by the network node that the first UE can perform the IDS based on subscription information of the first UE;

    transmitting, to the first UE, configuration information for the first UE (UE1 configuration information) to perform the IDS, the UE1 configuration information including information for configuring the IDS and a first IDS radio network temporary identifier (IDS-RNTI) assigned for indicating, by the network node, a resource allocation for the first UE to transmit data directly to the second UE; and

    transmitting a first control message addressed to the first IDS-RNTI, the message including radio resource information indicating a first radio resource for the first UE to transmit the data directly to the second UE and radio resource information indicating a second radio resource for the first UE to transmit one or more transmission parameters directly to the second UE, wherein the first radio resource is different than the second radio resource, and the transmission parameters include modulation and coding scheme of the direct data transmission.
