Abstract: A method and system for retransmitting data packets in a communication system having variable data rates is disclosed. In a preferred embodiment, data packets are packetized to an atomic packet size equal to that of a lowest rate packet. If a data packet requires retransmission at a rate different than that at which the data packet was initially transmitted, the rate is dynamically changed based upon a multiple of the atomic packet size.

Abstract: The present invention provides a method and apparatus for backhauling data in a communication system (100). A plurality of quality metrics are received at a centralized controller (105) from a plurality of base stations (101-104). The quality metrics are related to a data frame transmitted to the base stations (101-104) from a remote unit (113). A preferred data frame is determined from among the data frames. The centralized controller (105) then signals the base station associated with the preferred data frame to send the preferred data frame to the centralized controller.

Abstract: The present invention utilizes a cache which stores various decoded instructions, or parcels, so that these parcels can be made available to the execution units without having to decode a microprocessor instruction, such as a CISC instruction, or the like. This increases performance by bypassing the fetch/decode pipeline stages on the front end of the microprocessor by using a parcel cache to store previously decoded instructions. The parcel cache is coupled to the microprocessor fetch/decode unit and can be searched during an instruction fetch cycle. This search of the parcel cache will occur in parallel with the search of the microprocessor instruction cache. When parcel(s) corresponding to the complex instruction being fetched are found in the parcel cache a hit occurs and the corresponding micro-ops are then sent to the execution units, bypassing the previous pipeline stages.

Abstract: A method for allowing new traffic on a wireless data network. A service request is received from a mobile station (100). An effective bandwidth of the service request is estimated (110) using a recursive estimator (400). If there is enough surplus capacity on the wireless data network to accommodate the service request, the service request is granted. In response, a discrete adjustment, based on the effective bandwidth, is applied (160) to the recursive estimator (400).

Abstract: In a wireless communication system including at least a first (101) and a second base transceiver station (201), a method for providing time adjustment to the second base transceiver station (201) is presented. The method includes supplying an identity of the first and second base transceiver station to a mobile station (103), and based on the identity, tracking a first signal from the first base transceiver station (101) and a second signal from the second base transceiver station (201) by the mobile station (103). The method further includes determining a timing adjustment calculation based on a first time offset of the first and a second time offset of the second signal by the mobile station. And finally, the method includes transmitting the timing adjustment calculation to the second base station transceiver (201), the timing adjustment subsequently used to adjust the timing of the second base station transceiver (201).

Abstract: After determining a distressed mobile subscriber communication unit 100 is within a communication coverage area (60) of a base transceiver station (BTS) (22), a mobile BTS (55) positioned at a first location (201) uses a rotating directional antenna (46) to force mobile subscriber communication units including the mobile subscriber communication unit (100) to hand off communication. When the mobile BTS (55) detects the subscriber ID associated with the mobile subscriber communication unit (100) during handoff, a first direction of the directional antenna (46) is noted. The same procedure is repeated at another location (202) and a second direction of the directional antenna (46) is noted. A triangulation process using the first and second direction of the directional antenna and the first and second locations (201) and (202), reveal the location (203) of the mobile subscriber communication unit (100).

The method and apparatus include detecting a facsimile call origination from the originating facsimile machine, anticipating expiration of the start connect timer, and sending a benign signal to the originating facsimile machine prior to expiration of the start connect timer, wherein the benign signal allows the originating facsimile machine to receive a digital identification signal message from a terminating facsimile machine prior to expiration of the start connect timer.

Abstract: A communication system (28), comprises a master device (44) and slave device (30). Consequential to negotiations within the system (28) and having regard to system capacity and a relative hierarchy that exists between on-going communications, a bandwidth used for an on-going communication between the master device (44) and the slave device (30) is modified in proportion to a substantially instantaneous data rate requirement of the communication. As such, the system allows fluctuations in the amount of information, transmitted in a fixed time through an optimization of an available and dynamically varying bandwidth, while biasing the communication resource in relation to the relative hierarchy.

Abstract: The present invention provides for a method and apparatus for increasing the linearity of the phase and gain of an amplifier circuit (10, 22). The amplifier circuit (10, 22) maintains linearity of the amplified output signal by monitoring the power levels of the input signal, and adjusting the supply voltage level(s) of the amplifier (18), based upon the measured input power levels. By appropriately adjusting the supply voltage level(s) of the amplifier (18) an output signal having a consistent gain and phase can be realized. Preferably a delay circuit (26) will be used to delay receipt of the input signal by the amplifier (18), so as to synchronize receipt of the input signal with the corresponding source voltage adjustments. The value of the delay preferably corresponds to the time for the envelope detector (14) to measure the instantaneous input power levels and the time for the processing unit (16) to determine and apply the appropriate supply voltage level(s) to the amplifier (18).

Abstract: A method and system are disclosed where both a mobile station (105) and the infrastructure logically treat all access probes of an access attempt as if they were transmitted to a first base station (101). This is accomplished by having the mobile station (105) store both the registration parameters received from the first base station (101) to which an access probe is transmitted and a characteristic, such as the PN offset, of the first base station (101). When the mobile station (105) determines that it should perform an access probe handoff, it transmits an access probe to a different base station, identifying in the probe the characteristic, such as the PN offset, of the first base station (101). This allows the infrastructure to identify the base station that the mobile station (105) intends to register with. When the mobile station (105) receives acknowledgment to the access attempt, it then updates its registration variables with respect to the parameters received from the first base station (101).

Abstract: In a communication system (100) where a remote unit is given a time offset for a base station (102) and hands off to the base station (102) if the remote unit (113) can acquire the base station within a time window surrounding the time offset, a remote unit (113) utilizes the time offset of each base station (supplied by a serving base station (101) via a downlink communication signal (116) and searches for neighboring base stations within the time window surrounding its PN offset. The time window surrounding an individual base station's PN offset is allowed to vary depending upon whether the communication system (100) is time synchronized. In particular, a base station (101) supplies the remote unit (113) with an indication that the communication system (100) is operating in a synchronized or an unsynchronized mode, and the remote unit (113) varies the time window (search window) accordingly.

Abstract: The present invention provides a method for determining whether to handoff in a wireless communication system (100). The system (100) collects first environmental variables related to a first mobile station (105) within the wireless communication system (100). The system (100) determines when a communication between a base station (101) and the first mobile station (105) is improperly terminated. The system (100) analyzes, when the communication is improperly terminated, the first environmental variables to generate environmental conditions rules. The system (100) then applies the environmental conditions rules to a second mobile station (106) which subsequently communicates with the base station (101) and which has second environment variables substantially similar to the first environmental variables.
