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.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In an exemplary embodiment, the apparatus can receive a packet at a Uu protocol stack of a first user equipment (UE), the packet intended for a base station. In addition, the apparatus can transfer the packet from the Uu protocol stack of the first UE to a PC5 interface protocol stack of the first UE. Furthermore, the apparatus can modify a header of the packet at the PC5 interface protocol stack to identify the packet as relayed uplink traffic intended for the base station from the first UE. Moreover, the apparatus can transmit the packet including the modified header to a second UE for relaying to the base station.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. The apparatus may be a UE. The UE transmits a message to a base station. The message includes a status of the UE. The UE receives a DCI message from the base station based on the status. The DCI message includes transmit power control information for D2D communications. The transmit power control information indicates whether the UE can transmit at an allowed transmit power. The UE transmits data based on the transmit power control information received in the DCI message.

Abstract: Advertising wireless devices (e.g., user equipments (UEs)) within a distributed wireless network may indicate radio frequency and/or baseband capabilities (e.g., via transmitting capabilities messages). A responding UE may receive one or more capabilities messages, and identify radio frequency (RF) capabilities (e.g., indicated via a bitmap) and/or baseband capabilities of the advertising UEs. The responding UE may then determine a transmission scheduling policy based on the one or more received capabilities messages. For example, the responding UE may generate a combined list of frequencies based on the one or more received capabilities messages, and distribute transmissions over the list of frequencies. Additionally or alternatively, the responding UE may determine block decoding baseband capabilities of the one or more advertising UEs, and may accordingly enable block coding schemes for transmissions on frequencies supported by the advertising UEs with such block decoding baseband capabilities.

Abstract: Methods, systems, and devices are described for signaling device-to-device (D2D) capability information. A user equipment (UE) may determine a frequency band list of frequency bands supported for D2D proximity service communications. Based on the frequency band list, the UE may determine a proximity service record for a frequency band combination parameter, the frequency band combination parameter associated with non-D2D communications. The proximity service record may include a reduced capabilities record for the frequency band combination parameter that indicates reduced capabilities for non-D2D communications when D2D proximity service communications are active.

Abstract: The present disclosure enables a multicast and/or unicast transmitting UE to configure a multicast device-to-device communication and/or the unicast device-to-device communication such that UE may distinguish between the unicast and multicast device-to-device communications. The apparatus receives a unicast device-to-device communication including a destination identifier. The apparatus also receives a multicast device-to-device communication including the destination identifier. The apparatus differentiates the unicast device-to-device communication from the multicast device-to-device communication based on information provided in a header of the unicast device-to-device communication.
