摘要： Techniques may be used for interference measurement and management in directional mesh networks, including centralized and/or distributed approaches. A centralized node, such as an operations and maintenance (OAM) center, may use feedback from nodes in the mesh network to partition the nodes in the mesh network into clusters based on interference levels. Interference measurement reports may be used by the centralized node to update cluster membership. An initiating node in the mesh network may use topographical information to generate an initial interference cluster, and interference measurement frame (IMF) scheduling information may be used to schedule transmissions within the interference clusters. Techniques for opportunistic measurement campaigns, simultaneous measurement campaigns, link failure detection, and link re-acquisition in directional mesh networks may also be used.

摘要： Methods and apparatus for millimeter wave (mmW) beam acquisition are disclosed. An apparatus includes a transmitter configured to transmit millimeter wave (mmW) WTRU (mmW WTRU) information over a cellular system to a base station a receiver and a processor. The receiver receives a list of candidate mmW base stations (mB) including mmW acquisition start timing information from the base station, and the processor calculates correlation values around the received mmW acquisition start timing information for the mBs in the list.

摘要： Embodiments contemplate TDD systems and techniques where timeslots may be allocated as DL, UL, or FDSC; the base station (BS) may be full duplex singled channel (FDSC) capable; and some, all, or none of the UEs (or WTRUs) may be FDSC capable. In one or more embodiments, FDSC1 timeslots may be contemplated that may be used (in some embodiments perhaps exclusively used) by a pair of radios, for example one BS and one UE, both having FD capability. In one or more embodiments, FDSC timeslots may be shared among a BS with FDSC capability and two or more UEs, that may be half duplex (HD). Embodiments also contemplate various FDD systems and techniques, including full duplex FDD systems and techniques.

摘要： A cellular communications network may be configured to leverage a millimeter wave (mmW) mesh network. Base stations may be configured to operate as mmW base stations (tnBs). Such base stations may be configured to participate in the mmW mesh network and to access the cellular communications network (e.g., via cellular access links). A network device of the cellular communications network (e.g., an eNB) may operate as a control entity with respect to one or more niBs. Such a network device may govern mesh backhaul routing with respect to the cellular communications network and the mmW mesh network. Such a network device may configure the mmW mesh network, for example by performing a process to join a new mB to the mmW mesh network. A WTRU may send and receive control information via a cellular access fink and may send and receive data via the mmW mesh network.

摘要： A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.

摘要： A method and apparatus are described for providing improved channel estimation for wireless transmit/receive units (WTRUs) that require improved channel estimation (e.g., cell edge WTRUs) by allocating additional resource elements (REs) as pilot signals to improve channel estimation. These additional REs may be allocated to be used with expanded reference signals (ERSs).
