Abstract: User equipments (UEs) may transmit periodic discovery broadcasts to enable another UE to establish a relay connection to a network. When the UEs transmit respective discovery broadcasts, the discovery broadcasts may cause excessive utilization of network or battery resources. In some aspects, described herein, a first UE, based at least in part on failing to receive a periodic discovery broadcast, may transmit a search signal. A second UE may refrain from transmitting periodic discovery broadcasts based at least in part on a first energy metric not satisfying a first energy metric threshold, but may transmit a discovery broadcast as a response to the search signal based at least in part on a second energy metric satisfying a second energy metric threshold, thereby enabling the first UE to establish a connection to a base station using the second UE as a relay.

Abstract: Aspects of the present disclosure provide methods for modifying the numerology of the D2D frame structure to match the numerology of the Macro cell communication frame structure. Particularly, the present disclosure introduces techniques that allow the D2D devices to partition a long-TTI D2D transmission into a plurality of segments such that each segment may fit into a short-TTI MiCr uplink (UL) subframe. The present disclosure also provides techniques for scheduling D2D transmission and managing transmission power of the D2D communication to minimize the interference with the MiCr communication on the macro cell while maximizing the spectrum utilization.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may transmit feedback signaling for received sidelink messages to both the base station and the transmitting UE. The receiving UE may multicast a feedback message to both the base station and the transmitting UE on a physical uplink control channel (PUCCH) or on a physical sidelink feedback channel (PSFCH). The base station may configure the receiving UE with resources, the transmitting UE may allocate resources to the receiving UE, or the base station may actively monitor for the feedback message. In some examples, the receiving UE may operate in a dual connectivity mode, and may transmit the feedback message to both the base station and the transmitting UE on both the PUCCH and the PSFCH.
