Abstract: Some embodiments of this disclosure include apparatuses and methods for implementing a target wake time (TWT) scheme that includes traffic differentiation and service period extension. For example some embodiments relate to an electronic device including a transceiver and one or more processors communicatively coupled to the transceiver. The one or more processors receive an indication of traffic associated with an application. The one or more processors determine information associated with the traffic and configure the TWT scheme associated with the traffic based at least in part on the determined information. The one or more processors further communicate initial information associated with the TWT scheme to an access point of a wireless network. The initial information associated with the TWT scheme can include at least one of traffic direction information, traffic pattern information, a traffic identifier (TID), or an access category, indication (ACID).

Abstract: Methods for scheduling data packets based on a target transmission time may include receiving, from an application layer at a first time, a data packet and an associated latency requirement. The first layer may determine based, at least in part, on the associated latency requirement, a target transmission time. The target transmission time may be a sum of a queuing delay, an expected transmit completion time, and the first time. The data packet may be queued (or scheduled for transmission) based, at least in part, on the target transmission time and an access category assigned to the data packet. The data packet may be transmitted (or scheduled for transmission) from the queue according to the target transmission time. The expected transmit completion time may be a sum of an average contention time for the access category assigned to the data packet and estimated airtime.

Abstract: Methods, systems, and apparatus are presented for providing enhanced scheduling requests, e.g., in an IEEE 802.11 network. A client station (STA) may determine one or more minimum quality of service (QoS) metrics for supporting an application being implemented by the STA, and may determine minimum scheduling parameters to be implemented by an access point (AP) to achieve the minimum QoS. The STA may transmit to the AP a specific scheduling request indicating the minimum scheduling parameters. In response, the AP may schedule communication resources for the STA in accordance with the minimum scheduling resources.

Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, using a shared antenna, e.g., due to limitations resulting from a small form factor of the wireless communication device. The wireless communication device may determine whether communications according to a second protocol are causing performance of communications according to a first protocol to fall below a threshold level. If so, the wireless communication device may operate in a mode that favors communications according to the first protocol. If not, the wireless communication device may operate in a mode that favors communications according to the second protocol. For example, the mode that favors communications according to the first protocol may include temporarily implementing operations to remedy the poor performance of the communications according to the first, e.g., periodically, until the performance of the communications according to the first protocol recovers.

Abstract: Methods and apparatuses are presented to facilitate coexistence between multiple wireless communication protocols implemented by a wireless communication device, by dynamically adjusting priority between the two protocols. The wireless communication device may typically favor a first protocol (e.g. Bluetooth/BTLE), prioritizing resource requests by the first protocol. In certain use cases, the first protocol may demand high resource usage for an extended time, particularly for newer tracking and wearable devices, such as location tags, watches, headsets, etc. Such applications can disrupt existing use cases for a second protocol (e.g., Wi-Fi). Therefore, the wireless communication device may dynamically determine whether the second protocol is performing critical operations, such as latency-sensitive applications or high-performance operations. If so, the wireless communication device may allocate resources accordingly in real time, e.g., by reducing or limiting the resources assigned to the first protocol, to allow increased resources for the second protocol.

Abstract: An interface circuit in an electronic device (such as an access point) may request a channel status in order to specify a subset of one or more frequency sub-bands. During operation, the interface circuit may provide at least a frame to the recipient electronic device, where the frame requests the channel status for the one or more frequency sub-bands. Then, the electronic device may receive one or more measurement results from the recipient electronic device that specify the subset of the one or more frequency sub-bands (such as one or more RUs) that are not to be used when communicating with the recipient electronic device.

Abstract: A wireless device may use a 5 GHz frequency band to support both Wi-Fi and Bluetooth. The 5 GHz frequency band may be divided into two portions (e.g., high sub-band and low sub-band). A Wi-Fi module of the wireless device may perform a roam scan on a first sub-band to determine attempt to find a candidate channel that meets a target criteria. When the candidate channel that meets the target criteria is found on the first sub-band, the Wi-Fi module may join the candidate channel. If no acceptable candidate channel is found, the wireless device may perform a band switch protocol to allow the Wi-Fi module to preform a roam scan on a second sub-band.

Abstract: Embodiments disclosed herein relate to reducing power consumption of an electronic device scanning for wireless communication signals while maintaining or even improving an efficiency of the scanning operations. To do so, the electronic device may include more than one scan core, such as a main core and a receiving core. The receiving core may have limited functionality compared to the main core. For example, the receiving core may only receive wireless signals (including scanning for wireless signals). That is, the receiving core may not support certain operations that consume relative high power that are supported by the main core, such as transmission of signals. In this way, operation of the receiving core, either in place of or in addition to the main core, may reduce power consumption of the electronic device by avoiding high power consuming operations, such as data transmission, while scanning for various signals.

Abstract: Disclosed are methods, systems, and computer-readable medium to perform operations in a wireless device that includes a first radio that operates according to a first wireless protocol and a second radio that operates according to a second wireless protocol. The operations include determining that the first radio has received a grant to an antenna of the wireless device, where the wireless device further includes a secondary radio configured to perform actions according to the first and second wireless protocols. The operations also include selecting the first radio or the secondary radio to perform an action according to the first wireless protocol. Further, the operations include instructing the selected one of the first radio and the secondary radio to perform the action, thereby avoiding conflict between the primary radio and the secondary radio.
