Abstract: A system and method for reducing packet error rates for L2CAP PDUs with large payloads is disclosed. The Bluetooth device fragments the large payload in several packets in accordance with well known algorithms. However, prior to transmission, the Bluetooth device redistributes the payload among these packets to reduce the maximum payload that is transmitted in one packet. In one embodiment, the Optimum Slot Utilization algorithm is used to determine the number and types of packets to be used, as well as the payloads in each packet. Once this is determined, the Bluetooth device then redistributes the payload across these packets to reduce the size of the largest payload that is transmitted in any packet, while still maintaining the same number of packets.

Abstract: In one aspect, a method includes: transmitting, from a transmitter, a first packet to a device wirelessly coupled to the transmitter; in response to not receiving a response regarding the first packet from the device, retransmitting the first packet until a response is received; transmitting a plurality of second packets to the device, the second packets having a smaller width than the first packet; identifying a periodic polling interval at which the device communicates with another device; and adjusting a transmit clock slot and transmitting one or more third packets to the device according to the adjusted transmit clock slot.

Abstract: Methods and Wi-Fi devices that utilize the target wait time (TWT) feature of the Wi-Fi specification are disclosed. These methods reduce power consumption by selectively listening to only a portion of the beacons that are transmitted by the access point. In one scenario, the Wi-Fi device only listens to one beacon per TWT wake interval. In another embodiment, the Wi-Fi device may have knowledge of the application that is being executed, such as its allowable latency. The Wi-Fi device may use this allowable latency to determine when to exit low power mode to receive a beacon. Further, mechanisms to ensure that the connection between the Wi-Fi device and the access point are also disclosed. Additionally, techniques to maintain synchronization between the Wi-Fi device and the access point are disclosed.

Abstract: Systems and methods for reducing power consumption by using adaptive transmit power during sniff intervals are disclosed. The central device transmits the first packet of the sniff interval using the previously negotiated transmit power. After the central device receives a response from the peripheral device, the central device uses a lower transmit power for subsequent POLL packets during that sniff interval. This scheme may reduce the power consumption of the central device significantly, especially when a large number of packets are transmitted during each sniff interval.
