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.

Abstract: A method for encoding or transmitting. In some embodiments, the method includes forming a set of one or more unpunctured codewords by coding a plurality of payload bits at a mother code rate, removing a plurality of punctured bits from the set of one or more unpunctured codewords to form a set of one or more punctured codewords, and transmitting the set of one or more punctured codewords. In some embodiments, the number of punctured bits exceeds a first threshold, or the number of punctured bits exceeds a second threshold.

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.

Abstract: An electronic device configured to apply, to a first power amplifier (PA) input, one or more updated memory digital pre-distorter (mDPD) coefficient values is provided. The electronic device includes a processor; and a memory including a non-transitory computer readable storage medium storing instructions that, when executed, cause the processor to preload, from values stored in the memory of the electronic device, one or more mDPD coefficient values; transmit a training signal sequence while using the preloaded one or more mDPD coefficient values; receive the training signal sequence; update the one or more mDPD coefficient values based on the transmitted training signal sequence, the received training signal sequence, and the preloaded one or more mDPD coefficient values; and apply the updated one or more mDPD coefficient values to distort the first PA input.

Abstract: A method of implementing a hybrid automatic repeat request (HARQ) process. The method includes generating a HARQ transmission that comprises one or more HARQ units by: determining a HARQ unit size of the one or more HARQ units; generating the one or more HARQ units by assigning to each respective HARQ unit, based on the HARQ unit size, at least a respective portion of a media access control (MAC) layer data unit; and generating a header for the HARQ transmission. The method further includes transmitting the HARQ transmission to a receiver. The one or more HARQ units are physical layer data units.
