Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that a second UE is to transmit a control channel message retransmission using a first subchannel of a sidelink control channel during a subframe. The first UE may determine that the first UE is to transmit a sidelink transmission using a second subchannel of the sidelink control channel during the subframe, the second subchannel being different from the first subchannel. The first UE may transmit, by the first UE and during the subframe, the control channel message retransmission of the second UE using the first subchannel and the sidelink transmission of the first UE using the second subchannel.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may support layer-to-layer listen-before-talk (LBT) interfacing for logical discontinuous transmission (DTX) events. That is, a layer one entity of the base station may indicate to a higher layer that a channel is unavailable or experiencing high levels of interference. For example, a layer one entity of the base station may perform a failed clear channel assessment (CCA) or LBT procedure on the channel. The layer one entity may then convey an indication that a scheduled message was not successfully transmitted to a higher layer (e.g., a media access control (MAC) layer that performs link adaptation and scheduling). The higher layer may schedule a retransmission of the message based on the indication. In some cases, the same link parameters may be used. In other cases, the link parameters may be updated based on channel conditions.
