Patent number: 6914965Abstract: An apparatus and method of providing a reliable method of entering command mode and executing modem commands with a modem comprising a wireless communications channel. A wireless communications channel inserted into a standard modem configuration splits the functions of the modem between a mobile unit and a base station. When the system enters command mode, only the base station equipment changes state. The mobile unit continues to operate in the same manner as when the system is in data mode. Any command issued in command mode requiring action from the mobile unit is first sent to the base station. The base station recognizes that the command is intended for the mobile unit and sends a mobile unit-command over an independent private command channel to the mobile unit. The mobile unit constantly monitors the private channel regardless of the state of the system.Type: GrantFiled: September 30, 1994Date of Patent: July 5, 2005Assignee: Qualcomm IncorporatedInventors: Matthew S. Grob, Gadi Karmi

Publication number: 20040218570Abstract: A variable rate transmission system transmits a variable rate data packet including an accompanying rate indication signal indicative of the transmission rate of the variable data packet. The data packet can be spread using a long pseudonoise (PN) code, the mask of which can be selected in accordance with the transmission rate of the variable rate data packet. A preamble, providing the transmission rate, can be punctured into an outgoing pilot signal. The rate indication signal can be encoded in accordance with a set of orthogonal functions that are part of the indication of the transmission rate of the data packet.Type: ApplicationFiled: June 1, 2004Publication date: November 4, 2004Inventors: Peter J. Black, Gadi Karmi, Nagabhushana T. Sindhushayana

Patent number: 6807161Abstract: Reverse link busy bits are independently generated by each base station and indicate whether a base station has reached a reverse link capacity limit. A remote station combines multipath components of the reverse link busy bits in its Active Set and in response transmits a reverse link signal only when all of the reverse link busy bits indicate that the base stations in the Active Set have reverse link capacity. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines whether to transmit based on the weighted sum of the busy signals. In an embodiment, the remote station weights the reverse link busy signals in accordance with the signal strength of the transmitting base station and determines a maximum reverse link data rate based on the weighted sum of the busy signals.Type: GrantFiled: November 19, 2002Date of Patent: October 19, 2004Assignee: Qualcomm IncorporatedInventors: Paul E.

Publication number: 20040190471Abstract: A method and apparatus for rapidly assigning traffic channels to a plurality of mobile stations in a wide area high-speed packet data cellular communication system. Mobile stations transmit access probes on randomly selected access channels to selected base stations to initiate traffic channel assignments. The access probe comprises a pilot preamble, a traffic channel request, and a pilot/data request channel (DRC). The pilot preamble allows the selected base station to easily detect the access probe transmission. The traffic channel request includes data that identifies the mobile station. Immediately after transmitting the traffic channel request, the mobile station begins communicating with the base station on both the forward and reverse communication links. The selected base station immediately supervises the mobile station's transmission power. The mobile station selects from a group of available power control sub-channels.Type: ApplicationFiled: April 14, 2004Publication date: September 30, 2004Inventors: Paul E. Bender, Matthew S.

Publication number: 20030190937Abstract: A system and method for providing a simple, but effective technique for communicating overhead messages in a wireless communication system providing access to a decentralized network, while achieving bandwidth savings as well as minimizing power consumption. In one embodiment, a wireless base station which is connected to a decentralized network transmits a sequence of signatures for overhead messages to a mobile unit. The mobile unit wakes up receives the signatures and compares them to signatures stored at the mobile unit. If the signatures received by the mobile unit are different from the signatures stored at the mobile unit, the mobile unit stays awake to receive the overhead messages to be transmitted by the wireless base station. If the signatures received by the mobile unit are the same as the signatures stored at the mobile unit, the mobile unit may go back to sleep.Type: ApplicationFiled: September 22, 1998Publication date: October 9, 2003Applicant: QUALCOMM IncorporatedInventors: GADI KARMI, MATT GROB

Publication number: 20030152103Abstract: In a system including a resource which is shared among a number of users, it is difficult to distribute the available capacity of the resources fairly among the users and still maximize resource utilization. Additionally, it is desirable to allow at least some of the control over usage rates to remain with the users, while at the same time avoiding situations where the resource is overloaded. A system and method are disclosed wherein usage rates are selected from among a set of available rates according to a set of persistence vectors.Type: ApplicationFiled: February 20, 2003Publication date: August 14, 2003Inventors: Gadi Karmi, Matthew Stuart Grob, Paul E.

Publication number: 20030133494Abstract: The layers and protocols of an air interface layering architecture are designed to be modular and can be modified and upgraded to support new features, perform complex tasks, and implement additional functionality. Prior to commencement of data communication between a first entity (e.g., an access terminal) and a second entity (e.g., a radio network), a set of layers and/or protocols is selected for negotiation. For each selected layer and protocol (i.e., each attribute), a list of attribute values considered acceptable to the first entity is determined. The selected attributes and their associated attribute values are sent from the first entity and, in response, a list of processed attributes and their associated lists of processed attribute values are received. Each list of processed attribute values includes attribute values considered acceptable to the second entity.Type: ApplicationFiled: December 30, 2002Publication date: July 17, 2003Applicant: QUALCOMM, Inc.Inventors: Paul E.

Publication number: 20020132622Abstract: A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system.Type: ApplicationFiled: October 30, 1999Publication date: September 19, 2002Inventors: PAUL E.
