Abstract: The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a relay user equipment (UE) may receive, on a downlink channel from a network entity, at least one indication including resource allocation information for at least one of the relay UE or a remote UE. The relay UE may further transmit, on a sidelink channel to the remote UE, the resource allocation information of the remote UE. In another aspect, a remote UE may receive, on at least one sidelink channel, resource allocation information from a relay UE, the resource allocation information indicating one or more resources allocated for sidelink communication for the remote UE. The remote UE may further transmit, on one or more sidelink channels, data to the relay UE in accordance with the one or more resources allocated for sidelink communication.

Abstract: A method, computer-readable medium, and apparatus operate to reduce or eliminate interference with one or more other communication systems having specific transmission requirements within a specific geographic area. For example, aspects operate by determining that a user equipment (UE) is in a protection zone where additional transmission requirements apply. The additional transmission requirements enable coexistence with one or more other communication systems in the protection zone. The UE may identify, based on being in the protection zone and a coexistence mode, one or more transmit emission limit requirements to be met. The UE may identify, based on being in the protection zone and the coexistence mode, one or more maximum transmit power requirements to be met. The UE may configure a transmit output power, at which the UE can meet the one or more transmit emission limit requirements and the one or more maximum transmit power requirements.

Abstract: A cross-carrier scheduling scheme is provided. The cross-carrier scheduling scheme may improve the resource scheduling, for example, in V2X communication. The apparatus (e.g., a UE) receives a resource grant on a first carrier for a second carrier, the resource grant assigning resources for the second carrier. The apparatus communicates with a second UE via the second carrier using the granted resources. The apparatus may apply the resource grant based on at least one offset, such as an offset between the timing of the first carrier and timing of the second carrier.

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.
