Patent ID: 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.
