    Abstract: In order to reduce the power consumption associated with waking and receiving beacons, a current listening device in a group of electronic devices wakes and scans for a beacon from another electronic device (such as an access point) using a wireless-local-area-network (WLAN) communication protocol (such as Wi-Fi®). Then, the current listening device transmits information associated with the beacon to the group of electronic devices using a second communication protocol (such as Bluetooth® Low Energy), which is different than the WLAN communication protocol and has a lower power consumption. Moreover, the current listening device receives, using the second communication protocol, a sequence of responses from the group of electronic devices indicating that the information was received, wherein the responses from different electronic devices are received at different times. For example, the responses may be received in a predefined order and/or in round-robin fashion for the group of electronic devices.

    Abstract: Performing early termination of reception by a mobile station. The mobile station may receive a wireless transmission. The wireless transmission may include a physical layer (PHY) header, a media access control (MAC) header, and data. The mobile station may determine a duration and a destination address from the MAC header. The mobile station may determine if the wireless transmission is intended for the mobile station using the destination address. In response to determining that the wireless transmission is not intended for the mobile station, the mobile station may enter a low power mode prior to completion of the wireless transmission. The length of time of the low power mode may be based on the duration of the first wireless transmission.

    Abstract: Some embodiments enable improved packet error rate (PER), signal to noise ratio (SNR), channel capacity, aggregated throughput, and communication range in wireless communication systems. For example, an electronic device includes a buffer that stores a first descrambled bit estimate sequence. The electronic device further includes an encoder that receives a descrambling sequence and generates an encoded descrambling sequence and a multiplier circuit that receives a bit estimate sequence and the encoded descrambling sequence and generates a second descrambled bit estimate sequence. The electronic device also includes an adder circuit that combines the first descrambled bit estimate sequence and the second descrambled bit estimate sequence and a decoder that decodes the combined descrambled bit estimate sequence.

    Abstract: A wireless device can perform Out-of-Order packet processing and block acknowledgement. Multiple packets may be received at a lower layer of the wireless device. Identifying information may be determined for the received packets. It may be determined that the packets were received out of sequential order, based at least in part on the identifying information. Despite being received out of sequential order, payload information from the packets may be provided to a higher layer of the wireless device in a non-sequential order, such as the order of receipt.

    Abstract: This disclosure relates to wireless communication techniques. According to some embodiments, a wireless device may select a random number and sequentially advertise the bits of the random number. If the wireless device advertises the highest random number, it may proceed to transmit a packet using a channel. If another device advertises a higher number, the wireless device may not transmit its packet and may restart the process.

    Abstract: Embodiments described herein relate to a system and method for improving a rate of success in receiving response packets, such as 802.11 Acknowledge (ACK), Block Acknowledge (BACK), and Clear-To-Send (CTS) packets. In one embodiment, a wireless device may transmit one or more first packets according to a wireless communication protocol, and may then receive a second packet. The wireless device may determine that the receiving follows the transmitting by a specific duration of time that is specified by the wireless communication protocol for a response packet to follow one or more communication packets to which it responds. Based at least in part on this determining, the wireless device may further determine that the second packet is a response packet responding to the one or more first packets, without decoding a portion of the second packet that identifies a packet type of the second packet.
