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 system and method for managing latency in a wireless network. In some embodiments, the method includes: receiving, by a non-Access Point Station (non-AP STA), a first inserted packet; and sending, by the non-AP STA, an Acknowledgement (ACK) for the first inserted packet, the first inserted packet beginning after the beginning of a first originally scheduled Aggregated Physical layer Protocol Data Unit (A-PPDU) and being substituted for a portion of the data of the first originally scheduled A-PPDU.

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: 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.
