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: Systems, methods, and instrumentalities are disclosed for a WTRU to act as a mobile relay, the method comprising the WTRU connecting to the network, the WTRU receiving a message from the network indicating that the WTRU is to act as a mobile relay for one or more devices outside of the coverage of the network, the WTRU discovering one or more devices outside of the coverage of the network, and the WTRU receiving a message from the out-of-coverage device that indicates that the out-of-coverage device has selected the WTRU to act as a mobile relay.

Abstract: Systems, methods and instrumentalities may be provided for handling a user plane in a wireless communication system. The wireless communication system may be characterized by a flexible air interface. One aspect of the flexible air interface is that transmissions by a wireless transmit/receive unit (WTRU) in the system may have different quality of service (QOS) requirements, such as different latency requirements. The WTRU may adjust its behaviors based on the QoS requirements, e.g., by utilizing preconfigured resources, resource requests, self-scheduling, and/or the like, such that the transmissions may be performed in accordance with their respective QoS requirements.

Abstract: Systems, methods, and instrumentalities may be disclosed for implementing a flexible radio access communication system. A flexible radio access communication system may be supported using spectrum of varying size, including aggregation of non-adjacent carriers in the same and/or in different frequency bands. A wireless transmit/receive unit (WTRU) may receive a first transmission via a common downlink control channel. The first transmission may include first control information. The first control information may include information regarding the configuration of a first dedicated downlink control channel of one or more dedicated control channels. The WTRU may receive a second transmission via the first dedicated downlink control channel of the dedicated control channels. The second transmission may include second control information. The second control information may be associated with a transmission of a first transmission type. The dedicated downlink control channels may be used for providing control information associated with different types of transmissions.

Abstract: Logical channel (LCH) may be multiplexed together based on one or more latency requirements. Mapping of LCH(s) to spectrum operating mode(s) (SOM(s)) may be based on SOM capability and/or LCH requirements. A WTRU may determine mapping based on one or more pre-defined rules. The mapping may be based on one or more requirements for the various type of traffic and/or SOM capabilities. A radio bearer may be mapped to one or more SOMs. The WTRU may be configured with a set of SOMs, for one or more, or each, radio bearer. The WTRU may dynamically determine, for example based on radio conditions, buffer status and/or other parameters, the SOM to use. Incompatible multiplexing of LCH may be reduced and/or avoided, perhaps based on using one or more transport blocks (TBs) mapped to the same physical layer (PHY). Traffic may be prioritized based on one or more latency requirements.

Abstract: Embodiments contemplate wireless transmit/receive unit (WTRU) transmissions of different types of uplink channels and/or signals in a system deployment where multiple destination points may exist. Some embodiments contemplate that a WTRU may select the destination point of a transmission on a dynamic basis. In one or more systems where destination point selection from among multiple potential destination points may be possible for a WTRU transmission, some embodiments contemplate the determination of the handling of hybrid automatic repeat request (HARQ) retransmissions and for different power headroom reporting mechanisms. Embodiments also contemplate the reduction and/or inhibition of WTRU transmissions to destination points to which the WTRU may have lost connectivity.

Abstract: A WTRU may receive downlink control information (DCI) indicating a start of a frame. The DCI may be received on a control channel, such as the Physical Downlink Control Channel (PDCCH) from an eNB, base station, AP, or other infrastructure equipment operating in a wireless communications system. The WTRU may decode the DCI and may determine a transmit time interval (TTI) duration, which may be expressed in terms of an integer number of basic time intervals (BTIs). The WTRU may determine a downlink (DL) transmission portion and assignment and an uplink (UL) transmission portion and UL grant based on the received DCI. Additionally, the WTRU may determine the start of the UL portion based on an offset (toffset). The WTRU may receive data in a DL portion of the frame and may transmit in an UL portion of the frame based on the determined UL grant and TTI duration.

Abstract: A method and apparatus are described. A method includes determining whether the apparatus is in a coverage enhancement (CE) mode or a non-CE mode. The method further includes receiving a CE-system information block (CE-SIB) on a physical downlink shared channel (PDSCH) based on at least one of a known location or at least one known parameter for the CE-SIB, on a condition that the WTRU is determined to be in the CE mode.

Abstract: Systems, methods, and instrumentalities are disclosed to determine access control and channel and signaling priority. A wireless transmit/receive unit (WTRU) may comprise a processor configured, at least in part, to determine device-to-device (D2D) data to be transmitted. The WTRU may determine if the D2D data may be transmitted. The WTRU may determine available scheduling assignment (SA) resources used for priority based D2D data signals. The WTRU may select one or more available SA resources used for priority based D2D data signals. The WTRU may transmit the D2D data, wherein the D2D data may be transmitted on the selected SA resources.
