| 20110085630 | TCP FLOW CLOCK EXTRACTION - A packet trace is received. The packet trace is transformed into a sequence of pulse signals in a temporal domain. The sequence of pulse signals in the temporal domain is transformed into a sequence of pulse signals in a frequency domain. Peaks are detected within relevant frequency bands in the sequence of pulse signals in the frequency domain. A fundamental frequency is identified within the peaks. The fundamental frequency, which represents the TCP flow clock, is returned. | 04-14-2011 |
| 20110096662 | Inferring TCP Initial Congestion Window - A packet trace is received. Inter-arrival times between the multiple packets in the packet trace are determined. An inter-arrival time in the inter-arrival times that is greater than a threshold is identified. An order number of the inter-arrival time is identified. A determination is made as to whether a size of each of at least a portion of the multiple packets is equal to a maximum segment size. When a determination is made that the size of each of at least a portion of the multiple packets is equal to the maximum segment size a size of the ICW as a product of the order number and the maximum segment size is returned. | 04-28-2011 |
| 20110103256 | Detecting Irregular Retransmissions - A packet trace is received. Transmitted bytes and retransmitted bytes are identified in the packet trace. Upon identifying the transmitted bytes and the retransmitted bytes in the packet trace, one or more time-rate pairs are determined from the packet trace. The time-rate pairs are plotted on a rate tracking graph. | 05-05-2011 |

| 20080205374 | Pilot signal enhancements for a wireless communication system - In a method and apparatus suitable to convey timely information for facilitating accurate reception of transmitted data, a pilot signal is modulated to convey information. The information may facilitate efficient interpretation of an associated traffic signal. Modulation of a pilot signal frame may be limited to ensure early detection, and/or to minimize impairment of pilot functionality. In one embodiment, a Secondary Pilot Channel (SPICH) is transmitted at one of several selectable power levels to boost effectiveness of a phase reference, and is modulated to indicate the selected level. Such timely information enables prompt optimal combining of the SPICH with a primary Pilot Channel (PICH), and/or permits processing efficiencies for an associated traffic channel. Pilot signal frames may be transmitted at a predetermined level during a detection preamble portion of a frame to ensure accurate and early detection, and at a more optimal level thereafter. | 08-28-2008 |
| 20090319854 | TRISTATE REQUESTS FOR FLEXIBLE PACKET RETRANSMISSION - Extending acknowledgement messages from two states to at least three states is described, whereby such messages constitute a packet quality indication (PQI) reflecting quality or usability of the received signal. In an HARQ system, a transmitting station can flexibly select a better alternative for the next information to transmit on the basis of such PQI. One aspect includes determining how best to correct an unsuccessful packet transmission based on quality information about the specific packet. Implementing apparatus and procedures are described. | 12-24-2009 |
