  • Detection of punctured resources
    Patent number: 11139914
    Abstract: A receiver blindly determines which parts of the soft buffer to flush by comparing the reception of a first transmission to the reception of a second transmission (i.e., a re-transmission of the first transmission). Any large differences between the first and second transmissions are identified as puncturing events. After identifying the location of the puncturing events, the receiver then evaluates different hypotheses about which one of the transmissions was punctured in the different events. For each of the hypotheses the receiver attempts to decode the received data and the receiver stops processing once decoding is successful or after the receiver has processed all of the hypotheses.

  • Multi numerology transmission method for a radio communication system
    Patent number: 11063715
    Abstract: A first network node (200), a wireless device (202) and methods therein, for radio communication. The first network node determines first (2:1) and second (2:3) numerologies for communication of a reference signal and data, respectively, the first and second numerologies defining different combinations of subcarrier spacing and time between two successive OFDM symbols. The first network node then configures (2:4) the wireless device with the first and second numerologies and transmits (2:5) an assignment of data in the second numerology to the wireless device, the assignment comprising a trigger for the reference signal. Thereby, the first network node and the wireless device can communicate (2:6) the reference signal using the first numerology, and communicate (2:7) the data using the second numerology.

  • Discarding and retaining physical data channels
    Patent number: 10892874
    Abstract: A first channel for carrying Layer 2 messages carries data that will not be retransmitted and for which decoding-related information need not be retained by the receiving node in the event of an unsuccessful decoding of the data, while a second channel carries data that will be retransmitted in the event that a negative acknowledgement is received by the transmitting node. In an example method, first and second subsets of Layer 2 messages are received on first and second physical data channels, respectively. Decoding-related information for unsuccessfully decoded messages in the first subset is retained for use with subsequent retransmissions, while decoding-related information for unsuccessfully decoded messages in the second subset is discarded without waiting for retransmissions. Acknowledgements or negative acknowledgements are sent for messages in the first subset, but may or may not be sent for messages in the second subset, in various embodiments.
