    Abstract: A method and device are disclosed from the perspective of a first Wireless Transmit/Receive Unit (WTRU). In one embodiment, the method includes the first WTRU triggering a first buffer status report (BSR), wherein the first BSR indicates an amount of data expected to arrive. The method also includes the first WTRU triggering a second BSR, wherein the second BSR indicates an amount of data already available. The method further includes the first WTRU generating a MAC (Medium Access Control) PDU (Protocol Data Unit), wherein the MAC PDU includes at most one first BSR MAC CE (Control Element) for the first BSR and at most one second BSR MAC CE for the second BSR.

    Abstract: A method and apparatus are disclosed. A first sidelink Signaling Radio Bearer (SRB) for PC5-S message transmission is established. The first sidelink SRB is associated with a default Destination Layer-2 Identity (ID). A first PC5-S message is transmitted on the first sidelink SRB with a Source Layer-2 ID derived from a Layer-2 ID of the first UE and a Destination Layer-2 ID derived from the default Destination Layer-2 ID. A second PC5-S message is received from a second UE. The second PC5-S message is transmitted with a Source Layer-2 ID derived from a Layer-2 ID of the second UE and a Destination Layer-2 ID derived from the Layer-2 ID of the first UE. A second sidelink SRB for PC5-S message reception and/or transmission is established. The second sidelink SRB is associated with the Layer-2 ID of the second UE.

    Abstract: In an example, a UE receives, from a network, a configuration of a sidelink resource pool. Physical Sidelink Feedback Channel (PSFCH) resources of the sidelink resource pool are configured, periodically with a period of N slots, in slots of the sidelink resource pool. The UE receives, from the network, a configuration with a set of time offsets for determining an association set. The UE determines one or more slots. Each slot of the one or more slots is in the association set and contains a PSFCH resource of the sidelink resource pool. The UE generates a sidelink Hybrid Automatic Repeat Request acknowledgement (HARQ-ACK) codebook based upon one or more occasions associated with one or more PSFCH resources of the sidelink resource pool. The one or more occasions is determined or derived based upon the one or more slots and the period of N slots.

    Abstract: A method and apparatus are disclosed from the perspective of a second User Equipment (UE) for performing sidelink transmission to a first UE. In one embodiment, the method includes the second UE generating a MAC (Medium Access Control) CE (Control Element) with a fixed or (pre-defined) priority value, wherein the MAC CE is for transmitting to the first UE. The method further includes the second UE generating a MAC PDU (Protocol Data Unit) comprising the MAC CE and sidelink data from one or more sidelink logical channels, wherein the sidelink data is available for transmitting to the first UE. Furthermore, the method includes the second UE setting a priority field in a first SCI to a fixed or (pre-defined) priority value of the MAC CE. In addition, the method includes the second UE transmitting the first SCI to the first UE, wherein the first SCI schedules a first sidelink transmission for transmitting the MAC PDU.

    Abstract: A three-dimensional antenna element is provided. The three-dimensional antenna element is configured to be disposed on a surface of a conductive substrate, and includes a dielectric base, a first radiation part, a second radiation part, a third radiation part, a fourth radiation part, a first shorting element, and a second shorting element. The dielectric base includes a first plane and a second plane, where the second plane includes a first side and a second side, the first side is opposite to the second side and configured to be joined to the first plane, and the second side is configured to be joined to the surface of the conductive substrate. A signal feed-in point is coupled between the first radiation part and the second radiation part.

    Abstract: A method and apparatus are disclosed. In an example from the perspective of a User Equipment (UE), the UE receives, via a Radio Resource Control (RRC) message, a resource configuration of a first configured grant to be used in RRC inactive state. The UE performs a first new transmission using the first configured grant in RRC inactive state. After the performing the first new transmission, the UE receives an uplink grant in RRC inactive state via Physical Downlink Control Channel (PDCCH). The UE determines whether the uplink grant is for performance of a second new transmission or for performance of a first retransmission. The UE performs the second new transmission using the uplink grant in RRC inactive state if the UE determines that the uplink grant is for performance of the second new transmission.
