Abstract: A method for WTRU autonomous resource selection may comprise receiving a TX resource pool for D2D communication from a base station. The WTRU may sense one or more resources of the TX resource pool and determine resources for transmission of control information and D2D data, based on the sensing. The WTRU may then transmit, to another WTRU, the control information and the D2D data on the determined resources.

Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

Abstract: Methods and apparatuses are provided for generating a protocol data unit (PDU). An apparatus may comprise a processor configured to provide a medium access control (MAC) entity and a segmentation entity. The MAC entity may indicate an amount of data associated with the segmentation entity to be multiplexed by the MAC entity. The segmentation entity may segment, based on the indicated amount of data, a service data unit (SDU) into a segment, and the MAC entity may multiplex the segment into a MAC protocol data unit (PDU). The MAC PDU may include a field that indicates whether the segment is included and whether the segment is a last segment. The apparatus may further comprise a transmitter configured to transmit the MAC PDU.

Abstract: A method and apparatus for allocating resources to a wireless transmit receive unit (WTRU) includes the WTRU transmitting a signature sequence to a Node B, receiving an acknowledge signal from the Node B, and determining a default resource index. The resource index is associated with enhanced dedicated channel (E-DCH) parameters.

Abstract: Apparatus and methods of handing over a wireless transmit/receive unit (WTRU) that belongs to a group of WTRUs from an originating base station to a target base station are described. A method includes the WTRU obtaining information regarding a group to which the WTRU has been assigned and the WTRU receiving at least one of handover reconfiguration information that is common to the group and handover reconfiguration information that is specific to the WTRU. On a condition that the WTRU receives the handover reconfiguration information that is specific to the WTRU, the WTRU initiates a synchronization procedure with the target base station based at least on the received handover reconfiguration information.

Abstract: A method and apparatus for enabling scheduling and control of direct link communication in a cellular communication system may be disclosed. A method for use in a first wireless transmit/receive unit (WTRU) may include transmitting a request for device-to-device (D2D) communication resources to an enhanced Node B (eNB). The first WTRU may receive an allocation of resources for multiple transmission time intervals (TTI) to be used for D2D communications from the eNB. The first WTRU may schedule D2D communications with a second WTRU to be performed during the allocated resources. The first WTRU may perform D2D communications with the second WTRU using half duplex communications during the allocated resources.

Abstract: A method and apparatus are used for detecting a radio link (RL) failure and a post verification process. A quality of a downlink fractional dedicated physical channel (F-DPCH) is monitored once a transmission on an enhanced dedicated channel (E-DCH) has begun. It is determined whether the quality of the downlink F-DPCH is below a predefined threshold. If the quality is below the predefined threshold, then an occurrence of an RL failure is declared and a transmission over the E-DCH in a cell forward access channel (CELL_FACH) state is terminated. In a case of the post verification failure, E-DCH resources are released.
