    摘要: A method for preventing a relay node from missing a transmission from an access node. The method includes, when a ten millisecond periodicity is used for Multicast/Broadcast Single Frequency Network (MBSFN) subframes, setting a time between an uplink grant from the access node to the relay node and an acknowledgement/negative-acknowledgement message (ACK/NACK) from the access node to the relay node equal to ten milliseconds. The method further includes, when a forty millisecond periodicity is used for MBSFN subframes, the access node sending the relay node an asynchronous grant for an uplink retransmission when a data packet is missed, and when the relay node receives the grant for the uplink retransmission, the relay node retransmitting the missed data packet.

    摘要: A system is provided for transmitting a low code rate spatially multiplexed channel on multiple antennas. The system includes a transmitter and a processor. The processor is configured such that the processor encodes a block of information bits to form channel coded bits, wherein the ratio of the number of channel coded bits to the number of information bits is greater than one; and the processor maps the channel coded bits to modulation symbols, and each channel coded bit is mapped once to a modulation symbol. The transmitter is configured to transmit a first portion of the modulation symbols using a spreading sequence on a first antenna of the multiple antennas and to transmit a second portion of the modulation symbols using the spreading sequence on a second antenna of the multiple antennas.
