Abstract: System and methods for using channel quality reports to reduce inter-band interference are disclosed. Channel information is received at a first wireless communication device from a second wireless communication device. The first wireless device is operating in a first frequency range, and the second wireless device is operating in a second frequency range. The first frequency range is adjacent to the second frequency range. A channel quality report is generated at the first wireless communication device. The channel quality report indicates that particular sub-bands in the first frequency range have low channel quality. The particular sub-bands are selected using the channel information.

Abstract: A Wi-Fi device in a WLAN network includes a processor and a transceiver adapted to be coupled to an antenna, and a power saving medium access in congested network environments algorithm that is activated after a Wi-Fi connection is established with its access point (AP). A Traffic Indication Map (TIM) bitmap in a TIM information element received in a beacon frame from the AP is analyzed to determine whether more than a predetermined number of bits (X) are set to indicate the AP has ?1 buffered frame for ones of the Wi-Fi devices to conclude whether the WLAN is in a congested environment. When in a congested environment, transmissions responsive to the beacon are postponed by entering a sleep mode for a random period of time (P). After P expires, the sleep mode is exited and a poll frame is transmitted to the AP to try to gain medium access.

Abstract: Systems and methods for Transmission Control Protocol (TCP) acknowledgement (ACK) packet suppression are described. In various implementations, these systems and methods may be applicable to low-power communications. For example, a method may include receive an incoming TCP packet at a TCP layer implemented by the communication system; de-encapsulating the incoming TCP packet using a TCP protocol to identify an incoming Secure Sockets Layer (SSL) or Transport Layer Security (TLS) packet; passing the incoming SSL or TLS packet from the TCP layer to an SSL or TLS layer; and signaling, by the SSL or TLS layer to the TCP layer in response to the SSL or TLS layer having received the incoming SSL or TLS packet, that a TCP acknowledgement be suppressed by the TCP layer.

Abstract: A circuit includes a processor to store a beacon timestamp generated from a wireless network. An output port controlled by the processor causes an interrupt that initiates a capture of a link layer timestamp relative to the beacon timestamp. An input port on the processor receives the link layer time stamp. A synchronizer captures a processor timestamp relative to the beacon timestamp and determines a time offset value relative to the received link layer time stamp by computing a difference between the processor timestamp and the link layer timestamp. The time offset value is combined with the processor timestamp to synchronize the processor with respect to the beacon timestamp.

Abstract: In accordance with disclosed embodiments, a first wireless communication device operating in a first frequency band receives channel information from a second wireless communication device operating in a second frequency band adjacent to the first frequency band. The first wireless communication device generates a channel quality report indicating particular sub-band(s) in the first frequency band that cause interference in one or more channels in the second frequency band when used by the first wireless communication device for transmission. The channel quality report is sent by the first wireless communication device to a base station, which subsequently provides a sub-band assignment assigning one or more sub-bands within the first frequency band that avoid the one or more particular sub-bands indicated by the channel quality report. The first wireless communication device transmits the information using the one or more assigned sub-bands.

Abstract: A wireless communication device includes a processing unit with first chip and second chip that operates in parallel with the first chip. The first chip transmits/receives data according to LTE. The second chip transmits/receives data over a WLAN. The processing unit determines access points (AP) through which data can be transmitted/received by the second chip over the WLAN; and identifies an optimal AP, based on factors including a determination, for each AP, of whether transmission/reception of data by the first chip according to the LTE standard, simultaneous to transmission/reception of data over the WLAN by the second chip, would decrease the overall throughput of the first and second chips. When the second chip is previously connected to the WLAN through any AP other than the optimal AP, the second chip is disconnected from the other AP, and it is connected to the WLAN through the optimal AP.
