USER-EQUIPMENT-MANAGED DIRECT DEVICE TO DEVICE COMMUNICATIONS
Systems, methods, and apparatuses of a wireless communications network involve receiving 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 radio network identifier. A control message configured with the radio network identifier and a radio resource identifier may be received. Data can be transmitted directly from the first UE to the second UE during the IDS using the identified radio resource. A feedback signal can be received directly from the second UE in response to at least one IDS transmission
1 . A method performed by a first user equipment (UE) of a wireless communications network, the method comprising:
receiving 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 radio network identifier;
receiving a control message configured with the radio network identifier and a radio resource identifier;
transmitting data directly from the first UE to the second UE during the IDS using the identified radio resource; and
receiving a feedback signal directly from the second UE in response to at least one IDS transmission.
2 . The method of claim 1 , wherein transmission timing for the radio resource is based on a timing alignment for an uplink resource from the first UE to the network node.
3 . The method of claim 1 , further comprising transmitting a request, to a network node, for a transmission resource to send data from the first UE to the second UE.
4 . The method of claim 1 , further comprising transmitting data directly to the second UE during the IDS.
5 . The method of claim 1 , further comprising:
receiving a set-up message, the set-up message including an IDS physical uplink control channel (IDS-PUCCH1) that is associated with the IDS and configured for use with the radio network identifier; and
transmitting an uplink control message using an uplink resource provided by the IDS-PUCCH1.
6 . The method of claim 5 , wherein the uplink control message includes one or more of: an IDS schedule request, IDS channel state reporting, or IDS acknowledgement/negative acknowledgement (ACK/NACK) feedback.
7 . The method of claim 1 , further comprising measuring signals received from the second UE based at least partly upon the UE1 configuration information, and using the measurement to determine the IDS channel quality.
8 . The method of claim 1 , wherein the feedback signal is an acknowledgment/negative acknowledgement (ACK/NACK).
9 . A first user equipment (UE) comprising:
a transceiver configured to:
receive 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 radio network identifier;
receive a control message configured with the radio network identifier and a radio resource identifier;
transmit data directly from the first UE to the second UE during the IDS using the identified radio resource; and
receive a feedback signal directly from the second UE in response to at least one IDS transmission.
10 . The UE of claim 9 , wherein transmission timing for the radio resource is based on a timing alignment for an uplink resource from the first UE to the network node.
11 . The UE of claim 9 , wherein the transceiver is further configured to transmit a request, to a network node, for a transmission resource to send data from the first UE to the second UE.
12 . The UE of claim 9 , wherein the transceiver is further configured to transmit data directly to the second UE during the IDS.
13 . The UE of claim 9 , wherein the transceiver is further configured to:
receive a set-up message, the set-up message including an IDS physical uplink control channel (IDS-PUCCH1) that is associated with the IDS and configured for use with the radio network identifier, and
transmit an uplink control message using an uplink resource provided by the IDS-PUCCH1.
14 . The UE of claim 13 , wherein the uplink control message includes one or more of: an IDS schedule request, IDS channel state reporting, or IDS acknowledgement/negative acknowledgement (ACK/NACK) feedback.
15 . The UE of claim 9 further comprising a processor configured to measure signals received from the second UE based at least partly upon the UE1 configuration information, and using the measurement to determine the IDS channel quality.
16 . The UE of claim 9 , wherein the feedback signal is an acknowledgment/negative acknowledgement (ACK/NACK).
17 . A first user equipment (UE) comprising:
a transceiver configured to:
receive, from a network node, configuration information for an inter-device session (IDS) between the first UE and a second UE, the configuration information including a radio network identifier;
receive data directly from the second UE during the IDS using the identified radio resource; and
transmit a feedback signal directly to the second UE in response to at least one IDS transmission.
18 . The UE of claim 17 , wherein the transceiver is further configured to transmit data directly to the second UE during the IDS.
19 . The UE of claim 17 , wherein transmission timing for the radio resource is based on a timing alignment for an uplink resource from the second UE to the network node.
20 . The UE of claim 17 , wherein the feedback signal is an acknowledgment/negative acknowledgement (ACK/NACK).
