    • A two-way relay wireless communication method and device may combine multiple bit steams, for one source node and two target nodes, and broadcasting a network coded combined bit sequence to reduce the number of time slots for transmission. A first device may receive a signal from the source node and a target node simultaneously in a time slot. The first device may receive subsequent signals from the source node and multiple target nodes simultaneously in successive time slots. Hierarchical modulation may be applied to the received signals. The first device may decode the received signals and generate a plurality of intermediate bit sequences (IBS)s for a broadcast transmission. The generated IBSs may be grouped according to a channel condition. A second device may be configured to receive the broadcast transmission and decode a portion of the broadcast transmission that is intended for the second device.

    • 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.

    • A method and apparatus for estimating and reporting the quality of a wireless communication channel between a wireless transmit/receive unit (WTRU) and a Node-B. A modulated signal is received from the Node-B over the communication channel and a channel estimation is performed on the modulated signal to provide a channel estimate. In one embodiment, the modulated signal is demodulated based on the channel estimate to provide a demodulated signal and a signal-to-interference (SIR) estimate based on the demodulated signal is obtained. The quality of the communication channel is estimated based on at least the SIR estimate. In an alternate embodiment, a SIR estimate based on the channel estimate is obtained. The quality of the communication channel is estimated based on the SIR estimate and additional information including at least one of delay spread, transmit power and WTRU velocity information.
