Abstract
Systems, apparatuses, and methods for network-managed direct device-to-device communications are provided. Certain aspects of the disclosure involve transmitting, to a first UE, UE1 configuration information for an inter-device session (IDS) between the first UE and a second UE, the UE1 configuration information including a radio network identifier. Certain aspects of the disclosure also involve transmitting a control message to the first UE. The control message is configured with the radio network identifier and a radio resource identifier for the IDS, such that the first UE is permitted to transmit data directly to the second UE via the identified radio resource.
Claims23
A method performed by a network node of a wireless communications network, the method comprising:
- 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 including a first radio network identifier;
- and
- transmitting, to the first UE, a control message configured with the radio network identifier and a radio resource identifier, the radio resource identifier corresponding to a radio resource for transmitting data directly from the first UE to the second UE during the IDS.
A network node of a wireless communications network, the network node comprising:
- a transceiver configured to:
- transmit, to a first 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 first UE configuration information including a first radio network identifier;
- and
- transmit, to the first UE, a control message configured with the radio network identifier and a radio resource identifier, the radio resource identifier corresponding to a radio resource for transmitting data directly from the first UE to the second UE during the IDS.
A network node of a wireless communications network, the network node comprising:
- a transceiver configured to transmit, to a first 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 first UE configuration information including a first radio network identifier;
- and
- a processor configured to configure an IDS physical uplink control channel (IDS-PUCCH1) that is associated with the IDS, the IDS-PUCCH1 configured for use with the first radio network identifier;
- wherein the IDS-PUCCH1 is in addition to a physical uplink control channel (PUCCH) associated with a cell radio network temporary identifier (CRNTI) of the first UE.
