A UE may receive, via a first communication link that uses a first radio access technology (RAT), information that identifies a threshold associated with a second communication link that uses a second RAT. The UE may monitor one or more communications on the second communication link. The UE may determine whether a parameter associated with the second communication link satisfies the threshold based at least in part on monitoring the one or more communications on the second communication link. The UE may provide a message via the first communication link when the parameter associated with the second communication link satisfies the threshold.

Techniques for managing communication links of a plurality of radio access technologies (RATs)

In a particular aspect, a method includes performing a first communication operation associated with a first frequency band using an antenna of a wireless device. The first communication operation is initiated by first communication circuitry of the wireless device. The first communication circuitry is associated with a first communication protocol. The method further includes, based on a duration of a second communication operation, performing the second communication operation associated with a second frequency band using the antenna of the wireless device. The second communication operation is initiated by second communication circuitry of the wireless device. The second communication circuitry is associated with a second communication protocol that is different than the first communication protocol. The first frequency band at least partially overlaps the second frequency band.

Techniques for managing communication links of a plurality of radio access technologies (RATS)

In a particular aspect, a method includes receiving, at a long-term evolution (LTE) circuitry of wireless device from a wireless local area network (WLAN) circuitry of the wireless device while the LTE circuitry has control of at least one antenna of the wireless device, a request for control of the at least one antenna. Communications by the LTE circuitry using the at least one antenna corresponds to a first frequency band, communications by the WLAN circuitry using the at least one antenna correspond to a second frequency band, and the first frequency band at least partially overlaps the second frequency band. The method further includes sending a response from the LTE circuitry to the WLAN circuitry based on data included in the request.

Background scanning can include using a power save mode to momentarily suspend transmission between a current access point and a client. Information regarding other access points can then be collected. The client can return to the current access point before communication between the client and the current access point is disrupted.

Wireless LAN using background scanning technique

A key-caching system retrieves actively used keys from a relatively fast cache memory for fast processing of wireless communications. Additional keys are stored in relatively slow system memory that has high storage capacity. As keys become needed for active use, the keys are retrieved from the system memory and stored in the cache memory. By using active memory for keys actively being used, system performance is enhanced. By using system memory for keys not being used, a greater number of keys are available for transfer to the cache and subsequent active use.

Systems and methods to provide ordered transmission of data packets to multiple destinations are presented. A transmission device includes a transmitter, a data packet ordering unit, a state table, and a transmit management interface such as a hardware/software unit. The state table stores a transmit block status of each destination. The transmit management interface is coupled to the transmitter and analyzes data packets. The transmit management interface determines whether to transmit a data packet targeted to a particular destination or to block transmission of data packets to the particular destination by examining the transmit block status of the particular destination from the state table.

Method and system for transmit data blocking in a wireless communications network

A system for detecting and avoiding interference with radar signals in wireless network devices is described. The receiver circuit of the device receives incoming 5 GHz traffic. Such traffic could comprise both WLAN traffic as well as radar signals from radar systems. The incoming packets are treated as an input event, and are screened to be examined as radar pulses. Radar pulses are identified using the length of the detected event. The radar pulses are examined using frequency domain analysis, and the packet train is examined to find gaps between radar pulses. The periodic nature of the packet is determined using frequency domain and time domain analysis to calculate the period of the pulse train. Particular intervals within the pulse train are analyzed using threshold numbers of periodic pulses within the interval and threshold power levels for the pulses. The calculated period information is used to identify the radar source and screen non-radar traffic.
