1. A network node of a wireless communications network, comprising:
- a memory; and
at least one hardware processor communicatively coupled with the memory and configured to;
receive, from a first user equipment (UE), a request to perform an inter-device session (IDS) between the first UE and a second UE;
determine that the first UE can perform the IDS based on subscription information of the first UE;
transmit, to the first UE, configuration information for the first UE to perform the IDS, the configuration information for the first UE including a first IDS radio network temporary identifier (IDS-RNTI); and
transmit a first control message addressed to the first IDS-RNTI, the first control message including radio resource information indicating a first radio resource for the first UE to directly transmit data to the second UE and radio resource information indicating a second radio resource for the first UE to directly transmit one or more transmission parameters to the second UE, wherein the first radio resource is different than the second radio resource, and the transmission parameters include a modulation and coding scheme (MCS) for the direct data transmission on the first radio resource.

Abstract
Methods, systems, and apparatuses of a wireless communications network can involve transmitting, to a first user equipment (UE), configuration information for the first UE (UE1 configuration information) for an inter-device session (IDS) between the first UE and a second UE. The UE1 configuration information may include a first IDS radio network temporary identifier (IDS-RNTI). A radio resource control (RRC) message indicating a resource allocation can be transmitted to the first UE for the first UE to communicate directly with the second UE.

20. A non-transitory computer-readable medium containing instructions which, when executed, cause a network node to perform operations 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 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 to perform the IDS, the configuration information for the first UE including a first IDS radio network temporary identifier (IDS-RNTI); and transmitting a first control message addressed to the first IDS-RNTI, the first control message including radio resource information indicating a first radio resource for the first UE to directly transmit data to the second UE and radio resource information indicating a second radio resource for the first UE to directly transmit one or more transmission parameters to the second UE, wherein the first radio resource is different than the second radio resource, and the transmission parameters include a modulation and coding scheme (MCS) of the direct data transmission.
