Apparatuses, methods, and systems are disclosed for sidelink HARQ operation. One apparatus includes a memory coupled to a processor, where the processor is configured to cause the second apparatus to receive a SL grant for a SL transmission using SL resources, the SL grant indicating a first HARQ process identified by a first HARQ process identifier, and to select a second SL HARQ process identified by a second SL HARQ process identifier for the SL transmission using the SL resources. The processor is configured to cause the second apparatus to transmit SCI containing the second SL HARQ process identifier and to perform the SL transmission using the SL resources.

The disclosure relates to a mobile device, in particular a vehicle, or an application server, wherein the mobile device or the application server comprise: a processor, configured to: receive a notification from a network entity, in particular a base station, wherein the notification comprises information about available Quality of Service, QoS, and transmit a confirmation message to the network entity informing the network entity about an acceptance of the notified QoS. The disclosure further relates to a network entity, comprising: a network entity controller, configured to: transmit a notification to a mobile device, in particular a vehicle, or an application server, wherein the notification comprises information about available Quality of Service, QoS, and receive a confirmation message from the mobile device or the application server informing about an acceptance of the notified QoS.

Apparatuses, methods, and systems are disclosed for adjusting a contention window size. One apparatus includes a processor and a transceiver comprising a plurality of transmit panels. The transceiver initiates a first channel occupancy ('CO') using at least one transmit panel in response to a successful Listen-Before-Talk procedure and transmits a directional transmission using a first transmit panel, the first transmit panel selected from the plurality of transmit panels. The processor determines whether the directional transmission was successfully received by a recipient and updates a first contention window size specific to the first transmit panel. The processor performs a subsequent Listen-Before-Talk procedure using the updated first contention window size prior to a subsequent directional transmission using the first transmit panel.

The processor performs a directional LBT procedure for a first panel associated with the first UL channel resource and transmits request information to a RAN node using the first UL channel resource in response to successful directional LBT. The processor receives feedback information from the RAN node in response to the request information and transmits the first TB using the first UL channel resource in response to receiving the feedback information.
