摘要： Two network nodes may exchange messages through a relay using physical-layer network coding combined with forward error correction coding (FEC). The relay determines a prime field order based on the channel condition and communicates the field order to the network nodes. Each network node encodes an outgoing message with linear codes over a field such as finite field of the field order, and transmits a signal carrying the encoded outgoing message. The relay receives a composite signal carrying the summation of the messages from the two network nodes. The relay decodes the composite signal and extracts a composite message with linear codes over finite field of field order, and broadcasts a signal carrying the composite message. Each network node receives the signal from the relay and extracts the message intended for it using linear subtraction over finite field of field order.

摘要： A method and apparatus for transmitting and receiving orthogonal frequency division multiplex (OFDM)-based transmissions are disclosed. Control information may be transmitted at least one symbol prior to the corresponding data symbols so that a wireless transmit/receive unit (WTRU) has time to determine which parts of the subcarriers need to be received without having to buffer any corresponding data symbols. Control information related to frequency location of the data may be received in the first subframe and control information not related to the frequency location of the data may be received in the second subframe that includes the corresponding data. The offset between the control information and the data may be a fixed value, may be received from the network, or may be included in the control information preceding the corresponding data.

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 establishment of a milli-meter Wave (mmW) link communication include initial selection of candidate mmW Base stations (mBs) and configuration of mmW acquisition resources and procedures, both with the assistance of the cellular network. Further methods transmit mmW acquisition beacons, process mmW acquisition beacons to achieve mmW beam alignment and timing synchronization, and uplink (UL) reporting via cellular or mmW links. In an example, a mmW wireless transmit/receive unit (WTRU) transmits millimeter wave (mmW) WTRU (mmW WTRU) information over a cellular system to a base station, receives a candidate list of candidate mmW base stations (mB) including mmW acquisition start timing information and calculates correlation values around the received mmW acquisition start timing information for the mBs in the candidate list. The mmw WTRU performs sliding window correlations using signature sequences corresponding to mBs and beams in the candidate list.
