    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment). In one embodiment, the method includes triggering a BSR (Buffer Status Report). The method further includes transmitting a preamble for a random access procedure. The method also includes receiving a random access response for responding the preamble. In addition, the method includes creating a transport block based on an uplink grant provided in the random access response, wherein the transport block cannot include both a first CCCH (Common Control Channel) SDU (Service Data Unit) and a MAC (Medium Access Control) control element for BSR even if the uplink grant indicates a transport block size larger than or equal to a sum of a size of the first CCCH SDU and a size of the MAC control element for BSR. Furthermore, the method includes transmitting the transport block based on the uplink grant provided in the random access response.

    Abstract: A method and apparatus are disclosed, from the perspective of the UE, for performing random access procedure. In one embodiment, the method includes the UE receives a first back-off information from the network in a broadcast message, wherein the first back-off information includes a start offset of back-off interval. The method further includes the UE transmits a first preamble to the network. In addition, the method includes the UE determines a back-off interval based on the first back-off information and a second back-off information, wherein the second back-off information is received when the UE monitors a response for the first preamble. The method also includes the UE transmits a second preamble to the network after the back-off interval is finished.

    Abstract: A method and apparatus are disclosed for assisting data transmission in a wireless communication system. In one embodiment, the method includes a UE transmitting information to a base station, wherein the information at least indicates time to start an uplink transmission by the UE. In another embodiment, the method could include the UE receiving, from the base station, a configuration indicating a periodic uplink resource allocation. In addition, the method could include the UE performing the uplink transmission based on the periodic uplink resource allocation.

    Abstract: A method and apparatus are disclosed for handling multiple D2D grants for multiple sidelinks in decreasing order of priority. In one embodiment, the method includes a first UE participates in a first sidelink and a second sidelink, wherein a priority of the first sidelink is higher than a priority of the second sidelink. The method also includes the first UE receiving a first D2D grant and a second D2D grant from a base station in a first SA period. The method further includes the first UE serving the first sidelink with the first D2D grant and afterward, the first UE cannot serve the first sidelink with another D2D grant for the same SA period as the first D2D grant. In addition, the method includes the first UE serving the second sidelink with the second D2D grant and afterward, the first UE cannot serve the second sidelink with another D2D grant for the same SA period as the second D2D grant. Furthermore, the method includes the first UE using the first D2D grant for transmitting available data of the first sidelink and using the second D2D grant for transmitting available data of the second sidelink in a second SA period, wherein the second SA period and the first SA period are different SA periods.
