摘要： A method for multicasting a packet begins by providing a buffer for each of two user equipments (UEs) in communication with a base station. A determination is made whether there is a previously unsent packet at the base station. A second determination is made whether both UE buffers are non-empty. A non-empty buffer is flushed if there is no previously unsent packet and if one of the buffers is non-empty. A packet is selected to be transmitted if there is a previously unsent packet or if both buffers are non-empty. The buffers are updated based on feedback received from the UEs.

A wireless transmit/receive unit (WTRU) may listen to the base station (BS) transmission during Phase 1 of the communication, and use cooperation between a relay station (RS) and the BS for the data transmission during Phase 2 to improve performance. During Phase 2, both the BS and the RS may transmit data to the WTRU, using either distributed Space Time Block Codes/Space Frequency Block Codes (STBC/SFBC) or distributed spatial multiplexing.

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 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.
