US07742455B2 Scheduling method for wireless packet data channel
A scheduler at a base station may schedule packet data traffic based on a ranking metric that varies directly with the mobile station's scheduling downlink transmission rate and a delay factor indicative of the staleness of the corresponding queued data. The ranking metric may advantageously vary in a direct non-linear fashion with the delay factor to allow for delay sensitive data, such as VoIP data, to be scheduled with increased urgency when quality of service is about to be compromised. The scheduler may attempt to pack a multi-user downlink physical layer packet by selecting a tentative rate and determining if an aggregate amount of data in the packet may be increased by transmitting the packet at a lower rate. If so, additional queued data is added to the packet and the transmission rate for the packet is lowered. Such an approach allows for greater link efficiency to be achieved.

US07742447B2 Method and apparatus for performing acquisition in power save mode for wireless communication systems
Techniques to efficiently attempt acquisition of a packet data system (e.g., an IS-856 system). If a terminal has acquired one or more channels in a voice/data system (e.g., an IS-2000 system), then it can attempt acquisition on channels in the packet data system that are co-located with the acquired channels in the voice/data system. Multiple acquisition modes may be used, and on-going acquisition attempts on the co-located channels may be performed using one acquisition mode at a time in order to reduce power consumption.

For a ping-pong search, an acquisition attempt is made on the most recently acquired channel prior to an acquisition attempt on each of the remaining channels. Received signal strength estimates may also be obtained for selected channels and may be used to determine whether or not to attempt acquisition on these channels.

US07742443B2 Transmit power management in shared-communications channel networks
A method of ameliorating the hidden node problem in wireless local area networks employing power control is disclosed.

This causes at least one of the “loud” control frames to be heard and decoded by all of the potentially contending stations.

The control unit will continuously increase the packet sending rate until a packet is lost in the network between the transmission device and the destination point. On detection of packet loss, based on the lack of one or more corresponding acknowledgement messages from the destination point, the control unit will reduce the packet sending rate.
US07742418B2 Method and apparatus for determining latency and throughput of a data communication
The technology in this application determines the throughput over a data communication substantially as experienced by a user receiving the data. The determined throughput is substantially independent of the total amount of data transferred over the connection. This “active” throughput measure is divided into two parts to provide two performance measures: transfer throughput and latency. Latency corresponds to a time period needed to accomplish one or more functions associated with the data connection, like setting up and taking down the connection, during which payload type data to be transferred to an end user is not transferred. By identifying and removing the initial latency from the throughput determination for the data connection, the determined transfer throughput provides a more accurate measure of the throughput actually experienced by the end user.
