Resource scheduling in direct device to device communications systems

摘要

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.

主权项

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.
