  • Patent number: 11792835
    Abstract: Systems and methods for providing feedback regarding a wireless communication channel is disclosed. A responding processor is configured to estimate condition of the wireless communication channel and generate a data field. The data field includes a communication parameter based on the estimated condition of the wireless communication channel. The data field is attached to a control frame, and the control frame is transmitted with the attached data field. A transmitting processor is configured to receive the control frame, and determine whether the control frame includes the data field. The transmitting processor retrieves the data field from the control frame, and selects, based on the communication parameter in the data field, a transmit parameter for transmitting data over the wireless communication channel.

  • Publication number: 20230107677
    Abstract: A method of implementing a hybrid automatic repeat request (HARQ) process. The method includes: transmitting, by a transmitter to a receiver, an initial transmission of the HARQ process; receiving, by the transmitter from the receiver, receiver decoding capability information; setting, by the transmitter, a retransmission duration based on the receiver decoding capability information; and implementing, by the transmitter, a retransmission of the HARQ process based on the retransmission duration.
