    摘要: A visible light communication (VLC) device for lighting and data transmission is disclosed. The VLC device may comprise circuitry configured to receive a first stream of bits and determine a first switchpoint for transmitting the first stream of bits and first filler data. The VLC device may further comprise red, green, and blue (RGB) light emitting diodes (LEDs) configured to transmit the first stream of bits and the first filler data in the visible light spectrum. The first filler data may begin to be transmitted at the first switchpoint. Similar to the first stream of bits, a second stream of bits may be received and transmitted by the RGB LEDs of the VLC device. In this way, a naked eye of a human may not detect flicker of the VLC device.

    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: Methods and apparatus for changing cell range coverage are disclosed. The coverage may be changed on a per-sub-frame basis. An antenna beam elevation tilting angle may be adjusted to provide different effective downlink (DL) coverage. For example, a subframe may be a small tilt subframe or a large tilt subframe. A network or evolved NodeB (eNB) may determine data channel transmission power to adjust cell range per subframe. Low Power Subframe (LPS) may be used alone or with Almost Blank Subframe (ABS) to transmit data. Timing Advance (TA) handling for uplink (UL) transmissions is described. A common TA (CTA) may be determined for multi-site UL signaling. UL power control may be determined for UL transmission to multiple sites. Radio Link Monitoring (RLM) may be performed for multiple sites on a carrier frequency. A wireless transmit/receive unit (WTRU) may maintain synchronization in selected subframes for multiple cells.

    摘要: 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.
