Abstract: A method for dynamically controlling the transmit power of transmission streams transmitted via multiple antennas is disclosed. A transmit power level for multiple streams is determined based on a first reference channel. The difference of signal to interface ratios (SIRs) between two reference channels may represent a power offset. The power offset may be used to determine gain factors used to transmit data channels on the secondary stream with reference to the gain factor of the first reference channel. The power offset may be used to determine other parameters, such a serving grant or transport block sizes of channels carried on the secondary stream. The power offset may allow transmission parameters of channels on the secondary stream to be determined based on the transmit power level of the primary stream and a gain factor for a reference channel transmitted via the primary stream.

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.

Abstract: A wireless transmit receive unit (WTRU) may perform provide a report to a network. The WTRU may include a processor that is configured to receive a measurement configuration from the network, where the measurement configuration indicates a threshold and a resource pool on which to perform measurements. The resources pool may be used for communication between one or more mobile device. The processor may be configured to perform measurements on the resource pool and determine whether an energy level for the resource pool is above the threshold for a duration of time. The processor may also be configured to send a report to the network indicating that the energy level for the resource pool is above the threshold for the predetermined duration of time.

Abstract: A wireless transmit receive unit (WTRU) may be operated in a first scheduling mode for device-to-device communication. In the first scheduling mode, a network entity may schedule resources to be used by the WTRU for device-to-device communications. The WTRU may detect that a radio link failure (RLF) timer is running or has been started. The WTRU may switch from the first scheduling mode for Data device-to-device communication to a second scheduling mode for device-to-device communication in response to detecting that the radio link failure timer is running or has been started. In the second scheduling mode, the WTRU may select a resource from a resource pool for the WTRU to use for one or more device-to-device communications.

Abstract: A method and an apparatus for wireless transmission using multiple uplink carriers are disclosed. A wireless transmit/receive unit (WTRU) may transmit via a primary uplink carrier data, pilot and control channels for uplink transmissions on both uplink carriers, and transmit a data channel and a pilot channel via a secondary uplink carrier. Alternatively, the WTRU may transmit via a primary uplink carrier data, pilot, and control channels for uplink transmission on the primary uplink carrier, and transmit via a secondary uplink carrier data, pilot, and control channels for uplink transmissions on the secondary uplink carrier. Each uplink carrier may be associated with at least one specific downlink carrier such that the WTRU applies control information received on a downlink carrier to uplink transmissions on an uplink carrier associated with the downlink carrier on which the WTRU receives the control information.

Abstract: A wireless transmit/receive unit (WTRU) may communicate on a primary cell and a secondary cell. A transceiver of the WTRU may receive a medium access control (MAC) message indicating activation or deactivation of the secondary cell. A processor of the WTRU may start a timer in response to the activation of the secondary cell. The WTRU may deactivate the secondary cell on a condition that the timer expires.

Abstract: A method and apparatus for fast control channel feedback for multiple downlink carrier operations are disclosed. A wireless transmit/receive unit (WTRU) receives signals over a plurality of downlink carriers, generates feedback for each of the plurality of downlink carriers based on the received signals, and transmits via a plurality of antennas, the feedback for at least one of the plurality of downlink carriers over a first physical channel and feedback for another of the plurality of downlink carriers over a second physical channel.
