Publication number: 20090213805Abstract: Techniques for supporting data transmission on multiple carriers in a wireless communication system are described. A user equipment (UE) may determine available transmit power for data transmission on multiple carriers. The UE may distribute the available transmit power to multiple carriers (e.g., using uniform power distribution, greedy filling, water filling, etc.) to obtain allocated transmit power for data for each carrier. The UE may send at least one resource request with information indicative of the allocated transmit power for each of the multiple carriers to a Node B. The UE may receive at least one resource grant with information indicative of granted transmit power for each of at least one carrier, which may be all or a subset of the multiple carriers. The UE may send data on the at least one carrier and may limit its transmit power for each carrier to the granted transmit power for that carrier.Type: ApplicationFiled: February 26, 2009Publication date: August 27, 2009Applicant: QUALCOMM IncorporatedInventors: Danlu Zhang, Mehmet Yavuz, Bibhu P.

Publication number: 20090201871Abstract: Providing for improved wireless communications for user equipment (UE) in a semi-active state is described herein. By way of example, a base station can employ particular wireless channel resources, monitored by a UE in a CELL_FACH state for instance, to trigger channel feedback information from the UE. The trigger can comprise an explicit order instructing the UE to provide data in response, or can include a portion of downlink traffic targeting the UE, where the UE is configured to respond in a suitable manner to receipt of traffic data. The UE can maintain the CELL_FACH state in receiving to and responding to the trigger, and can further receive subsequent traffic data in such state. Accordingly, the subject disclosure provides for improved efficiency and reliability in semi-active state wireless communications.Type: ApplicationFiled: February 11, 2009Publication date: August 13, 2009Applicant: QUALCOMM, IncorporatedInventors: Sharad Deepak Sambhwani, Bibhu P.

Publication number: 20090034474Abstract: Systems and methods for dynamically adjusting the transmission time interval (TTI) for a communications system are presented. The described aspects provide for dynamically adjusting the TTI in a communication session between a base station or nodeB and a wireless device or user equipment between a shorter TTI, which can provide increased data throughput and lower power consumption, and a longer TTI, which can provide more rugged communication link connections. By dynamically adjusting the TTI, the communications link can be optimized for the given communication channel conditions. Determinations, based on indicia related to the communications system conditions, can be employed in dynamic TTI adjustment. These determinations can be formed centrally at the Radio Network Controller (RNC), at the RNC supplemented with user equipment (UE) available information, or formed in a distributed manner between the RNC and UE across a communications system.Type: ApplicationFiled: April 17, 2008Publication date: February 5, 2009Inventors: Mehmet Yavuz, Bibhu P.

Patent number: 7319872Abstract: A system and method for providing mobile switching center (MSC) initiated service negotiation in a wireless communication system. If a new call arrives for a subscriber unit while the subscriber unit is already on the traffic channel, a change in the service configuration may allow the subscriber unit to receive the new call while preserving the old call. MSC initiated service negotiation may be used to establish the change in service configuration. The MSC transmits a Change Service Command message to the base station in whose coverage area the subscriber unit is located. The Change Service Command proposes a new service configuration to accommodate both the old and the new call. The base station, subscriber unit, and MSC may interchange further messages to modify the proposed service configuration if necessary. Messages are exchanged until the base station, subscriber unit, and MSC reach an agreement regarding the new service configuration. The present invention also provides support for soft handoff.Type: GrantFiled: December 21, 2000Date of Patent: January 15, 2008Assignee: QUALCOMM IncorporatedInventors: Rajeev Krishnamurthi, Bibhu P. Mohanty, Roy F. Quick, Jr.

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.
