Abstract: A wireless transmit/receive unit (WTRU) receives first timing advances and first power control commands from a first eNodeB and second timing advances and second power control commands from a second eNodeB and transmits, to the first eNodeB, a first physical uplink control channel using a first uplink component carrier. The first physical uplink control channel has a first timing adjusted by the first timing advances but not by the second timing advances and a first power level adjusted by the first power control commands but not by the second power control commands. The WTRU transmits a second physical uplink control channel using a second uplink component carrier. The second physical uplink control channel has a second timing adjusted by the second timing advances but not by the first timing advances and a second power level adjusted by the second power control commands but not by the first power control commands.

Abstract: A method and apparatus are described. A wireless transmit/receive unit (WTRU) includes circuitry that determines transmission power levels associated with physical uplink shared channel (PUSCH) transmissions over a plurality of uplink component carriers. On a condition that maximum power scaling is required, the circuitry prioritizes providing power to a physical uplink control channel (PUCCH) over providing power to a physical uplink shared channel (PUSCH) having uplink control information (UCI) and prioritize providing power to the PUCCH and PUSCH having UCI over a PUSCH not having UCI. The circuitry transmits the PUCCH, the PUSCH having UCI or at least one PUSCH not having UCI over the plurality of uplink component carriers.

Abstract: A method, apparatus and system for wireless communication are described. The method includes transmitting and receiving data to and from one or more wireless transmit/receive units (WTRUs) via an underlay system access link. The underlay system is non-standalone, and control information is provided from an overlay system. An underlay base station is linked to other underlay base stations to implement a mesh backhaul. The method also includes transmitting and receiving at least a portion of the data to or from an overlay base station via backhaul links and receiving control data from the overlay base station. The data is split at a packet data convergence protocol (PDCP) entity, and the PDCP entity terminates in the overlay base station and a radio link control (RLC) entity terminates in the underlay base station.

Abstract: Methods and apparatuses are provided herein. A method may include receiving, from a first network node, configuration information to establish a link to a second network node. The first network node may use a first radio access technology (RAT) and the second network node may use a second RAT. The configuration information may include timing information associated with a first one of a plurality of beams of the second network node. The method may include measuring the first one of the plurality of beams of the second network node based on the timing information. The method may include selecting a beam of the plurality of beams of the second network node based on the measurement. The method may include sending a transmission to at least the first network node. The transmission may be an indication the WTRU is configured to establish the link to the second network node.
