Abstract: Some examples of the techniques described herein may provide schemes to organize shaped payload bits, non-shaped payload bits, and parity bits to allow an increased quantity of bits to be shaped for enhanced performance. Interleaving may be utilized in some aspects to enhance robustness to burst errors. For instance, interleaving schemes for enhancing bit orderings and interleaving are provided. In some approaches, permutation and row-column interleaving may be performed with a quantity of rows. Some approaches may utilize circular rotation and row-column interleaving with a quantity of rows. In some examples, permutation with alphabet-based row-column interleaving with fixed rows may be performed. Some aspects may include permutation and row-column interleaving with a quantity of rows when punctured columns are shaped. In some approaches for modulation mapping, each set of bits may be mapped to a quadrature amplitude modulation (QAM) symbol.

Abstract: Methods, systems, and devices for wireless communications are described. A shared channel may include a set of tones carrying multiple types of control information multiplexed together. A wireless device may perform a tone classification method to determine individual subsets of tones from the set of tones for each type of control information to extract each type of control information. The wireless device may determine multiple subsets of tones correspond to multiple types of control information simultaneously based on different extraction parameters. For example, the wireless device may determine a total number of tones in a set of tones, a distance between any given two tones in the set of tones, an offset value, or any combination thereof for the extraction parameters. The wireless device may then use these extraction parameters to determine or extract two or more subsets of tones for two or more corresponding types of control information.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device may transmit a signal to a second device including a number of error detection bits interleaved with a number of information bits. The second device may use the error detection bits to determine if the signal was received correctly, where each error detection bit may be associated with a set of information bits. The second device may progressively decode the signal and continuously perform an error detection calculation based on a first set of information bits associated with a first error detection bit. Based on the error detection calculation, the second device may calculate an expected error detection bit corresponding to the first error detection bit. The second device may compare the first error detection bit to the expected error detection bit. Other aspects and features are also claimed and described.

Abstract: Systems, methods, and other embodiments associated with unified control of timing recovery and packet processing are described. According to one embodiment, a method for performing unified control of timing recovery and packet processing is provided. The method includes sampling a received signal according to an ADC timing signal to produce a sequence of samples. The received signal corresponds to a packet and was transmitted according to a transmit timing signal. The method includes determining a phase offset between the ADC timing signal and the transmit timing signal and identifying, based, at least in part, on the phase offset, a data portion of the sequence of samples that contains data encoded in the received signal. A re-generated sample sequence that adjusts the data portion based on the phase offset is calculated.

Abstract: A receiver is provided and includes a first amplifier configured to amplify, based on a first gain, a radio frequency signal to generate a first amplified signal. The radio frequency signal is received by the receiver on a first channel. A second amplifier generates, based on the first amplified signal and a second gain, a second amplified signal. An output circuit generates a baseband signal based on the second amplified signal. A first detection circuit compares the baseband signal to (i) a first threshold in response to the first gain being at a first level, and (ii) a second threshold in response to the first gain being at a second level. The first detection circuit generates a first detection signal in response to the comparison. A controller, in response to the first detection signal, (i) adjusts the second gain, or (ii) changes the receiver from the first channel.

The amplifier receives RF signals and amplifies those signals. The amplifier has an adjustable gain value. The signal detection circuit detects whether a received signal is an out-of-band radar signal depending on the gain value of the amplifier and a characteristic of the received signal.
