Abstract: Examples herein include apparatus and methods for overriding a media access control module acknowledgment and non-acknowledgment scheme. In one example, a codec module determines if an error-corrected packet is acceptable in response to the detection by the media access module of an uncorrectable error in a received packet, and overrides the media access control module to prevent a non-acknowledgment response from being sent when the error-corrected packet is acceptable.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for the described techniques provide for generating, by an encoding device, one or more entropy symbols, the length of which changes responsive to errors, stacking the entropy symbols into fixed intervals, and selecting a parity bit. The encoding device may divide entropy symbols that are longer than the fixed interval duration and stack the excess portions of the long entropy symbols with shorter entropy symbols in other intervals. The encoding device may transmit the stacked data packet according to the stacking. A decoding device may receive the data packet, identify the locations of the entropy symbols and the selected parity bit, check the parity of each entropy symbol, identify error bits based on the locations of the entropy symbols within multiple fixed intervals, and may correct error bits based on the stacked intervals, the parity bit, and an error mask.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may communicate, during a first communication period, with an audio device via a wireless link configured with a first service interval and a first service period. The WCD may communicate, during a second communication period, with the audio device via the wireless link configured with a second service interval and a second service period based at least in part on detection of a trigger condition comprising one or more of: a change of a signal strength, a change of one or more concurrent wireless links on one or more frequency bands that overlap with the wireless link, a change of a use state of the WCD, or a change in channel congestion or interference. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first peripheral device may establish, with a user equipment (UE), a first connected isochronous stream (CIS), a second CIS, and a control channel for the first CIS and the second CIS, where the first peripheral device is configured to output audio signals for the first CIS and handle feedback for the first CIS. The first peripheral device may transmit, to a second peripheral device paired with the first peripheral device, an indication that the second peripheral device is to output audio signals for the second CIS and handle feedback for the second CIS. The first peripheral device may receive the first CIS, while maintaining the control channel for the first CIS and the second CIS. Numerous other aspects are described.

Abstract: Methods, devices, non-transitory computer-readable medium, and systems are described for compressing audio data. The techniques involve obtaining a sequence of digitized samples of an audio signal, performing a transform using the sequence of digitized samples, to generate a plurality of spectral lines, obtaining a group of spectral lines from the plurality of spectral lines, and quantizing the group of spectral lines to generate a group of quantized values. Quantizing the group of spectral lines to generate the group of quantized values may comprise performing a specialized rounding operation on a spectral line selected from the group of spectral lines and using the specialized rounding operation to force a group parity value, computed for the group of quantized values, to a predetermined parity value. One or more data frames based on the group of quantized values may be outputted.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device (WCD) may perform a clock tracking procedure that comprises: transmitting, to an access point (AP), an extended personal area network (XPAN) synchronization message pair that is addressed to a peripheral device associated with the WCD, and receiving, from the AP, an XPAN synchronization response message pair that is associated with the XPAN synchronization message pair. The WCD may transmit, to the AP, user data that is addressed to the peripheral device at a time that is based at least in part on an estimated awake window, the estimated awake window being based at least in part on the XPAN synchronization response message pair. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a peripheral device may synchronize a local clock to an access point timing synchronization function clock (TSF_AP) that is maintained by an access point (AP) connected to the peripheral device. The peripheral device may maintain, based at least in part on the local clock, an estimated time-to-play timing synchronization function clock (TSF_est) that is associated with outputting user data. The peripheral device may receive, from the AP, timing synchronization information that is based at least in part on a comparison between a wireless communication device (WCD) time-to-play timing synchronization function software clock (TSF_soft) and the TSF_est. The peripheral device may output the user data based at least in part on the TSF_est and the timing synchronization information. Numerous other aspects are described.
