Abstract: A system can configure a first number of demodulation reference signal (DMRS) positions in radio resource control information as part of a connection setup with a user equipment that is configured to facilitate broadband cellular communications, wherein the broadband cellular communications are facilitated with carrier aggregation of a primary cell and a secondary cell. The system can, after attaching to the user equipment, send a first message to the user equipment indicative of modifying the first number of DMRS positions to a second number of demodulation reference signal positions for first communications via the primary cell. The system can send a second message to the user equipment indicative of modifying the DMRS positions for second communications via the secondary cell. The system can conduct the broadband cellular communications with the user equipment according to the second number of DMRS positions.

Abstract: Various arrangements for short-range wireless communication are presented herein. An earbud of a pair of true wireless earbuds can receive an audio packet addressed to the other earbud of the pair. A single connected isochronous stream (CIS) within a connected isochronous group (CIG) may be present between the pair of true wireless earbuds and an audio source which transmitted the audio packet. The earbud can transmit a cross-acknowledgement indicating receipt of the audio packet to the other earbud. The earbud can also transmit audio data from the audio packet to the other earbud after the cross acknowledgement.

Abstract: Various arrangements are presented that can help preserve bandwidth, such as for audio communications involving high fidelity audio being transmitted to wireless earbuds. A first earbud can receive an audio packet from an audio source device that includes stereo audio separately encoded as a first monophonic channel and a second monophonic channel. The first earbud can determine that it successfully received the audio packet. The second earbud may not successfully receive the audio packet. Thus, the second earbud can make a request to the first earbud. The first earbud can then directly transmit to the second earbud, audio data for only the second monophonic channel from the audio packet. Each earbud can then output its respective monophonic audio channel.

Abstract: A system can communicate broadband cellular communications with a base station. The system can receive a radio resource control message from the base station to establish a sounding reference signal mode for the broadband cellular communications, wherein the sounding reference signal mode is a periodic mode. The system can receive a second message in a second format from the base station, wherein the second format differs from a radio resource control format, and wherein the second message indicates changing a number of sounding reference signal positions. The system can send, to the base station, a third message that utilizes the number of sounding reference signal positions to convey sounding reference signal information, wherein, responsive to the sending, channel quality data is stored that comprises an indication of a channel quality that corresponds to the broadband cellular communications based on the third message.

Abstract: The system can send a radio resource control (RRC) message to user equipment (UE) to establish a sounding reference signal (SRS) mode for broadband cellular communications, where the SRS mode is periodic, and the communications are facilitated with carrier aggregation. The system can send a second message in a second format to the UE, where the second format differs from a RRC format, and the second message indicates changing a number of SRS positions for the primary cell. The system can send a third message in the second format to the UE, where the second message indicates the changing of the number of SRS positions for the secondary cell. The system can receive, from the UE, a fourth message that utilizes the number of SRS positions to convey SRS information. The system can save an indication of a channel quality that corresponds to the communications based on the SRS information.

Abstract: Various embodiments for managing utterance data latency over Bluetooth Low Energy (BLE) are described herein. The techniques described use a CIS connection for communicating an utterance received by an earbud to the audio host (AH). The CIS connection can be used to transmit utterance data (e.g., a hotword followed by a user request) to a computing device to help to improve a user experience by reducing latency in interacting with a virtual assistant or perform some other operation.

Abstract: Various arrangements for managing a relay link bandwidth over Bluetooth Classic and Bluetooth Low Energy (BLE) are described herein. According to techniques described herein, the Bluetooth bandwidth used by the earbuds for relay Determine Bandwidth Used For Audio Transmissions within traffic between the earbuds is directed at being optimized for the audio use cases by using a dynamic placement scheme and configuring a secondary earbud (e.g., an earbud that does not include an established connection with the AH) to be in the central role on the relay link between the earbuds. In the dynamic placement scheme, instead of reserving a predetermined number of slots for the voice traffic before a predetermined number of slots for the relay traffic, the relay traffic can be dynamically placed/moved after the voice traffic ends if voice traffic doesn't use all the reserved bandwidth and hence, some of the voice traffic's reserved bandwidth could be used for the relay traffic.

Abstract: One example method includes while an incremental backup of files is being performed, scanning, by a slicer, a directory that includes the files, keeping a count of the files that have been scanned, determining, by the slicer, when a file size threshold, or a file number threshold, has been exceeded, and when the file size threshold, or the file number threshold, has been exceeded, recording, by the slicer, as a sub-slice, the file(s) that were the basis for the determination that one of those thresholds had been exceeded.

Abstract: Various arrangements for managing Bluetooth Low Energy (BLE) bandwidth usage across different devices are described herein. The techniques described include prioritizing HID traffic over Close Isochronous Event (CIE) traffic. Generally, a CIE is used by a computing device (e.g., a call gateway) to indicate that audio traffic for the event has been successfully delivered and received by another computing device. Using the techniques described herein, the user experience can be improved by helping to ensure that not only the user experience of the audio traffic is good, but also that the user experience with other HIDs are good (e.g., improved HID latency).

Abstract: Various arrangements are described for performing dynamic spatial audio communications. Inertial measurement unit (IMU) data may be created based on movement of the audio output system.

Despite the audio packet being successfully received by the primary earbud, a negative acknowledgement may be transmitted to the audio source device in response to determining that data of the audio packet has not yet been transmitted a predefined number of times.
