摘要： Concepts and schemes pertaining to location of interleaver with low-density parity-check (LDPC) code are described. A processor of an apparatus encodes data to provide a stream of encoded data. The processor also rate matches the encoded data to provide a rate-matched stream of encoded data. The processor further interleaving the rate-matched stream of encoded data. In rate matching the encoded data, the processor buffers the stream of encoded data in a circular buffer, with the circular buffer functioning as a rate matching block that rate matches the stream of encoded data. In interleaving the rate-matched stream of encoded data, the processor performs bit-level interleaving on the rate-matched stream of encoded data to provide a stream of interleaved data.

摘要： A Hybrid Automatic Repeat Request (HARQ) feedback scheme that employs a multi-state NACK feedback processing is proposed. A transport block (TB) contains a plurality of code blocks (CBs). When all CBs of the TB are successfully decoded, a one-bit TB ACK is feedback. When at least one CB of the TB is not correctly decoded, a one-bit TB NACK is feedback. In addition, a multi-bit HARQ CB NACK feedback is provided. The multi-bit HARQ CB NACK can point more precisely to the erroneous parts of the TB and trigger efficient retransmission by skipping retransmission of successfully decoded CBs. The network can disable the multi-bit CB NACK for certain UEs, e.g., to reduce overhead. The UE can disable the multi-bit CB NACK, e.g., to save power.

摘要： A transceiver architecture with combined digital beamforming and analog/hybrid beamforming is proposed. Digital beamforming is used for beam training with reduced overhead (switching time). It is beneficial to estimate all UE's angle of arrival (AoA) at the same time. In addition, the pilot/training signals are transmitted in a narrow band to reduce complexity. Analog/hybrid beamforming is used for data transmission with high directive gain and low complexity. The value of beamforming weights (phase shifter values) in analog domain can be based on the estimation of AoA from beam training. By using digital beamforming for beam training, combined with analog/hybrid beamforming for data transmission, effective beamforming is achieved with reduced overhead, complexity, and cost.

摘要： A beamforming system synchronization architecture is proposed to allow a receiving device to synchronize to a transmitting device in time, frequency, and spatial domain in the most challenging situation with very high pathloss. A detector at the receiving device detects the presence of control beams, synchronizes to the transmission and estimates the channel response by receiving pilot signals. The detector has low complexity when exploiting the structure of the pilot signals. The detector consists of three stages that break down the synchronization procedure into less complicated steps. The detector accurately estimates the parameters required for identifying the transmit device and performing subsequent data communication.

摘要： A beamforming system synchronization architecture is proposed to allow a receiving device to synchronize to a transmitting device in time, frequency, and spatial domain in the most challenging situation with very high pathloss. A periodically configured time-frequency resource blocks in which the transmitting device uses the same beamforming weights for its control beam transmission to the receiving device. A pilot signal for each of the control beams is transmitted in each of the periodically configured time-frequency resource blocks. Pilot symbols are inserted into pilot structures and repeated for L times in each pilot structure. The L repetitions can be implemented by one or more Inverse Fast Fourier Transfers (IFFTs) with corresponding one or more cyclic prefix (CP) lengths.

摘要： A method of supporting group communication over LTE MBMS is provided. A UE first establishes a unicast Evolved Packet Service (EPS) bearer in an LTE network for group communication. The UE belongs to a communication group having a communication group ID. The UE receives access information from the network for monitoring downlink (DL) multicast traffic of the DL group communication based on a multicast decision. The UE is then ready for monitoring a multicast Multimedia Broadcast Multicast Service (MBMS) bearer for receiving the DL multicast traffic. The multicast MBMS bearer is associated with a Temporary Mobile Group Identifier (TMGI), and wherein the TMGI is associated with the communication group ID. The UE de-multiplexes DL traffic received either from the multicast MBMS bearer or from the unicast EPS bearer into a single group communication application.
