    Publication number: 20230421287
    Abstract: A method of a transmitter enables multi-site wireless transmission using complementary channel coding. The method includes receiving a message to be transmitted to a receiver, encoding the message as a first codeword using a shared mother code, parsing the first codeword into a first complementary codeword of a set of complementary codewords specific to the first codeword, determining a set of shared channel resources and a configuration of the transmitter to be utilized to transmit the first complementary codeword, and transmitting the first complementary codeword to the receiver.

  • Configurable timing relationship and HARQ operational parameters
    Patent number: 10931409
    Abstract: Systems and methods for determining configurable timing relationships and operational parameters are provided. In some embodiments, a method of operation of a wireless device in a wireless system includes determining round-trip propagation delay information between the wireless device and a network node. This round-trip propagation delay information may be a round-trip propagation delay a quantized round-trip propagation delay, or any other value indicative of the round-trip propagation delay. The in method also includes determining a Hybrid Automatic Retransmission Request (HARQ) operational parameter based on the round-trip propagation delay information between the wireless device and the network node. In this way, HARQ is extended to work for deployments with large round-trip propagation delays, such as satellite systems. This may increase the throughput and reliability of data transmission.

A transmitting network node can transmit a message label to a receiving network node across a backhaul link. The receiving network node can transmit a message label to the wireless terminal. The wireless terminal can identify a stored message that corresponds to the received message label, and send the corresponding message to the receiving network node. The receiving network node can then transmit the message to its intended destination.
