Abstract: The present disclosure provides a solution to this problem by enabling the communications network to verify the relationship of the first UE and the second UE based on stored pairing information that is used to verify that the first UE is allowed to make a connection to the communications network. The apparatus transmits a pairing request from a first UE to a second UE. In an aspect, the pairing request is intended for a communication network. Further, the apparatus receives a pairing acknowledgement. In an aspect, the pairing acknowledgement verifies the pairing of the first UE and the second UE. In addition, the apparatus connects to the communication network via the second UE once the first UE pairs with the second UE.

Abstract: In one aspect of the disclosure, to improve the performance of device-to-device based relay communication, a method, a computer-readable medium, and an apparatus for performing rate control based on feedback from participating UEs are provided. The apparatus may be a first UE. The first UE may receive a signal from a second UE through a device-to-device communication channel. The first UE may determine a feedback based on the received signal. The first UE may transmit the feedback to adjust transmission of the signal at the second UE. In another aspect of the disclosure, a first UE may transmit a signal to a second UE through a device-to-device communication channel. The first UE may receive a feedback of the signal. The first UE may adjust transmission of the signal based on the feedback.

Abstract: One problem with current D2D communications is that there is no physical layer feedback (e.g., HARQ feedback) for unicast sidelink communications. That is, the transmitting UE does not know if the receiving UE receives and/or properly decodes the unicast transmission. Instead, current D2D communications require that a transmitting UE send a unicast sidelink communication multiple times to increase the chances that the unicast sidelink communication is received by the receiving UE. By blindly transmitting unicast sidelink communications multiple times, the spectral efficiency and radio resource utilization of the network is decreased. The present disclosure provides a solution to this problem by enabling HARQ feedback for unicast sidelink communications that improves the spectral efficiency and also enables better radio resource utilization for the network.
