Abstract: A game apparatus repeatedly switches between a doze state in which a wireless communication function is restricted, and an awake state. The game apparatus stores unicast data and broadcast data acquired in the awake state, in a normal queue, and transmits the pieces of data to air in acquisition order. On the other hand, in the doze state, the game apparatus stores acquired broadcast data in a preferential transmission queue, and stores acquired unicast data in the normal queue. Thereafter, when the game apparatus becomes the awake state again, the game apparatus transmits the broadcast data stored in the preferential transmission queue in preference to the unicast data stored in the normal queue.

A wireless low energy module of the computing device is monitored for a remote start signal from a remote device, and the at least one of the hardware subsystems that is in an idle state is powered up in response to receiving a remote start signal from a remote device. The remote-start advertisement is then ended in response to the at least one of the hardware subsystems powering up.

Abstract: Method for reducing collisions between a first station and a second station in a CSMA/CA system. The method may be performed by the first station. Medium access to transmit to the second station may be obtained according to a first procedure for obtaining medium access. It may be determined that the second station is configured to grant transmit opportunity to the first station. Medium access to transmit to the second station may be obtained according to a second procedure for obtaining medium access based on determining that the second station is configured to grant transmit opportunity to the first station. The first procedure may include contending for medium access, while the second procedure may include delaying contention for medium access relative to the first procedure.

Abstract: This disclosure is directed to wireless or wired multiple-input multiple-output communication systems, in which a transmit symbol vector and a set of soft decision metrics are estimated using a reduced complexity maximum likelihood (ML) detection method based on a receive symbol vector and a QR decomposition of a set of permuted channel matrices. The QR decomposition can be performed by a series of CORDIC operations. Preferably, the modified receive vector and upper triangular matrix streams are scaled by a weighting vector to help compensate for transmit and receive side noise. Also preferably, the soft decision metric set related to the reliability of transmitted bits is normalized.

Abstract: Communicating among stations in a network includes providing repeated beacon transmissions from at least some of the stations including a first station. The first station is assigned to a first level. Any stations that can reliably receive transmissions from the first station are assigned to a second level. Any stations not assigned to any of the preceding levels that can reliably receive transmissions from the preceding level are assigned to each of one or more higher levels. Timing information at each station in a given level is synchronized according to transmissions received from at least one station in the preceding level.

Abstract: A method of performing dynamic sounding in a wireless communication device includes determining whether to perform sounding based on an age of current channel state information (CSI). An achievable throughput can be recorded as a reference throughput after performing the sounding. A current achievable throughput can be compared with the reference throughput. A CSI timestamp can be reset when the current throughput is above the reference throughput by a first predetermined amount, thereby prolonging a lifespan of the current CSI. The CSI timestamp can be reduced when the current throughput is below the reference throughput by a second predetermined amount, thereby reducing the lifespan of the current CSI.

Abstract: The listen interval of a WLAN client is selected to have one of a plurality of values, including a start listen interval (SLI) and one or more longer listen intervals (e.g., transient listen interval (TLI), maximum listen interval (MLI)). The listen interval is set to SLI in response to (1) detecting that an applications processor of the WLAN client is in an awake state, (2) detecting transmit/receive activity on the wireless link, and (3) failing to detect an expected beacon signal on the wireless link. If the listen interval is set to MLI (or TLI) and the WLAN client fails to detect an expected beacon signal (beacon miss), the listen interval is temporarily set to SLI. If the WLAN client then detects an expected beacon signal before detecting a predetermined number of consecutive beacon misses, the listen interval is immediately returned to the original listen interval MLI (or TLI).

The signal processing unit generates samples of the voltage estimates of the common mode signal component. The signal processing unit adjusts transmit voltage levels of the powerline communication device based on the samples of the voltage estimates of the common mode signal component to limit the common mode signal component of the output signal.

Abstract: A hybrid device can apply forwarding tables associated with one or more other hybrid network devices of a hybrid communication network to control the entire transmission route of a frame scheduled for transmission. The hybrid device can use its forwarding table and a forwarding table of a destination hybrid device to determine a source network interface address, a destination network interface address, and a frame transmission route. The destination hybrid device can use forwarding tables associated with one or more hybrid network devices to determine whether to process or drop a received frame, whether the frame was previously received, and/or whether the frame was received on an incorrect network interface. The hybrid device can also use the forwarding tables to ensure that the frame comprises an appropriate link layer address and to select an appropriate transmission route based on analyzing link performance values associated with multiple transmission routes.

Abstract: A network based positioning (NBP) system that improves the accuracy of wireless positioning systems by concurrently performing RTT ranging operations and associated TDOA operations to generate a number of difference measurement values from which the position of a station device (STA) can be determined using, for example, multilateration techniques. Because the RTT values and their corresponding TDOA values both include the turn-around time (TAT) of the STA, subtracting TDOA values from their corresponding RTT values generates difference measurement values that do not include such TAT values of the STA. In this manner, the STA position can be determined without estimating the STA's TAT.
