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 method and system for hybrid automatic repeat request operation for uplink coordinated multi-point signaling, the method in one embodiment sending a data packet from a user equipment to a plurality of network elements; waiting for a control indication from at least one of the plurality of network element; and retransmitting the data packet to the plurality of network elements if the control indication specifies retransmission is required.

A method for discontinuous reception operation for carrier aggregation comprising: receiving a first set of discontinuous reception parameters for a first carrier and a limited or different set of discontinuous reception parameters for a second carrier; and configuring discontinuous reception parameters on the first carrier and second carrier.
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.

摘要:
A method for transmitting data to a user agent. The method includes a relay node receiving information from an access node, the information containing the data that is to be transmitted to the user agent and control information that the access node will use to transmit the data to the user agent. The method further includes the relay node transmitting the data to the user agent at the time the access node transmits the data to the user agent, the relay node using the control information that the access node uses to transmit the data to the user agent.
摘要:
A user agent comprising a processor enabled to configure the user agent to adjust a discontinuous reception (DRX) start offset when a downlink assignment is one of configured and reconfigured. The DRX start offset is adjusted to satisfy the equation (10*SFNstart time+subframestart time)modulo(Long DRX Cycle)=DRX start offset.
