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: A method and apparatus for power control for distributed wireless communication is disclosed including one or more power control loops associated with a wireless transmit/receive unit (WTRU). Each power control loop may include open loop power control or closed loop power control. A multi-phase power control method is also disclosed with each phase representing a different time interval and a WTRU sends transmissions at different power levels to different set of node-Bs or relay stations during different phases to optimize communications.
Abstract translation: 公开了一种用于分布式无线通信的功率控制的方法和装置，其包括与无线发射/接收单元（WTRU）相关联的一个或多个功率控制回路。 每个功率控制回路可以包括开环功率控制或闭环功率控制。 还公开了一种多相功率控制方法，每个阶段表示不同的时间间隔，并且WTRU在不同阶段期间以不同功率电平向不同组的节点B或中继站发送传输，以优化通信。

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.
