    Abstract: A method and apparatus are disclosed. In an example, a first user equipment (UE) may be configured with a first number of carriers corresponding to a maximum number of carriers that the first UE is able to use concurrently and/or transmit on concurrently. The first UE may receive a plurality of sidelink transmissions on a plurality of carriers. The first UE may derive a plurality of slots for transmitting Physical Sidelink Feedback Channels (PSFCHs) based upon resources associated with the plurality of sidelink transmissions. Responsive to determining that a number of carriers of a second plurality of carriers associated with derived transmissions of the PSFCHs exceeds the first number of carriers, the first UE may prioritize one or more PSFCHs of the PSFCHs based upon a rule. The plurality of slots for transmitting the PSFCHs may be at least partially overlapped in the time domain.

    Abstract: Methods and apparatuses for improving retransmission scheduling of sidelink communications are disclosed herein. In one method, a first device monitors a down control signal for scheduling sidelink resource. The first device performs a sidelink transmission for a second device based on a first sidelink grant allocated by a base station. The first device determines a retransmission need of the sidelink transmission based on a Hybrid Automatic Repeat Request (HARQ) feedback of the sidelink transmission from the second device. The first device transmits a retransmission indication for the retransmission need to the base station. The first device starts or restarts a timer upon the transmission of the retransmission indication, wherein the timer is used for controlling a period of monitoring a downlink control resource set.

    Abstract: A method and apparatus are disclosed from the perspective of a first device for performing sidelink communication. In one embodiment, the method includes the first device being configured with network scheduling mode for sidelink by a base station. The method further includes the first device being configured with a first set of resources with a first time pattern for sidelink transmission through a dedicated signaling. The method also includes the first device using the first set of resources to perform sidelink transmission when the first device does not detect beam failure. Furthermore, the method includes the first device detecting a beam failure between the first device and the base station. In addition, the method includes the first device using the first set of resources to perform sidelink transmission to a second device when the beam failure is not resolved.

    Abstract: A method and apparatus are disclosed from the perspective of a UE for requesting SPS resources for V2X message transmissions in a wireless communication system. The method includes generating a first V2X message for transmission. In addition, the method includes transmitting a first signal to a network node for requesting SPS resources for transmitting the first V2X message and V2X messages which are generated subsequent to the first V2X message, wherein the first signal includes an identity used to associate the SPS resources with the first V2X message and the V2X messages. Furthermore, the method includes receiving a second signal from the network node, wherein the second signal contains a first information indicating the SPS resources and the identity. The method also includes transmitting the first V2X message and the V2X messages according to the SPS resources indicated by the first information.
