  • Publication number: 20190372593
    Abstract: According to certain embodiments, a method is provided for fast layered decoding for Low-density Parity-Check (LDPC) codes with a Parity-Check Matrix (PCM) that includes at least a first layer and a second layer. The method includes reading, from a memory, Variable Node (VN) soft information, wherein the VN soft information is associated with a message from a VN to a Check Node (CN) of the second layer of the PCM. A new CN to VN message is calculated from the CN of the second layer of the PCM. New VN soft information is calculated for the VN. The new VN soft information is calculated based on the VN soft information and a new CN to VN message from a CN of the first layer to the VN and an old CN to VN message from the CN of the first layer to the VN such that the updating of new VN soft information is delayed by at least one layer. The fast layered decoding has lower decoding latency and utilizes the decoding hardware more efficiently than standard layered decoding techniques.

  • Publication number: 20190356430
    Abstract: A method for use in a transmitter includes sending a transmission comprising a transport block (TB) comprising a plurality of code blocks (CBs) arranged in one or more code block groups (CBGs). Each code block group includes one or more code blocks and each code block includes a plurality of coded bits. The transmission is sent to a receiver configured to use multi-bit hybrid automatic repeat request (HARQ) feedback per transport block. The method further includes receiving HARQ ACK or NACK feedback from the receiver one or more of the one or more code block groups of the transport block. The method further includes determining a number of code blocks or code block groups to send to the receiver in a retransmission based on at least the received HARQ ACK or NACK feedback.

  • Publication number: 20190327032
    Abstract: Systems and methods are disclosed herein that allow a radio access node to command a wireless device to clear parts of a soft buffer for a Hybrid Automatic Repeat Request (HARQ) process. In some embodiments, a method for a wireless device in a wireless communications system comprises receiving control information comprising information pertaining to whether the wireless device should partially clear a soft buffer for a HARQ process, deciding whether to partially clear the soft buffer for the HARQ process based on the information comprised in the control information, and partially clearing the soft buffer for the HARQ process upon deciding to partially clear the soft buffer for the HARQ process. In this manner, corrupted soft information can be cleared from the soft buffer while retaining uncorrupted soft information in the soft buffer.

  • Patent number: 10361821
    Abstract: In one aspect, a wireless device receives a first data transmission from a base station during a predetermined subframe interval and within a duration that is less than a maximum data transmission duration that is possible within the predetermined subframe interval, and determines a transmission time for transmitting HARQ feedback to the base station such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used for the first data transmission. The wireless device transmits HARQ feedback for the first data transmission at the determined transmission time. In another aspect, a base station transmits the first data transmission and determines a reception time for receiving HARQ feedback such that the determined transmission time depends on which subset of symbols within the predetermined subframe interval was used. The base station receives HARQ feedback for the first data transmission at the determined transmission time.
