摘要： Se describen técnicas para gestionar la operación de un equipo de usuario (UE) en un sistema de portadora múltiple; el sistema puede soportar dos o más portadoras en el enlace descendente y una o más portadoras en el enlace ascendente; una portadora en cada enlace puede ser designada como una portadora de anclaje; en un aspecto, se puede utilizar una orden de capa inferior (por ejemplo, una orden de HS-SCCH) para cambiar el UE entre la operación de portadora sencilla y portadora múltiple; en otro aspecto, el UE puede tener la misma configuración de recepción discontinua (DRX) para todas las portadoras de enlace descendente y/o la misma configuración de transmisión discontinua (DTX) para todas las portadoras de enlace ascendente; en otro aspecto todavía, la operación sin HS-SCCH puede ser restringida a la portadora de anclaje.

摘要： Techniques for managing operation of a user equipment (UE) in a multi-carrier system are described. The system may support two or more carriers on the downlink and one or more carriers on the uplink. One carrier on each link may be designated as an anchor carrier. In an aspect, a lower layer order (e.g., an HS-SCCH order) may be used to transition the UE between single-carrier and multi-carrier operation. In another aspect, the UE may have the same discontinuous reception (DRX) configuration for all downlink carriers and/or the same discontinuous transmission (DTX) configuration for all uplink carriers. In yet another aspect, HS-SCCH-less operation may be restricted to the anchor carrier.

摘要： Techniques for controlling transmission of packets on multiple links are described. In one design, a transmitter may generate packets of data for a receiver, assign the packets with sequence numbers from a single sequence number space, demultiplex the packets into multiple streams for multiple links, and send each stream of packets os the associated link to the receiver. The receiver may receive some packets in error, and the correctly received packets may be out of order. In one design, the receiver may maintain the largest sequence number of correctly received packets for each link. After detecting at least one missing packet, the receiver may send status information conveying the missing packet(s) and the largest sequence numbers for all links to the transmitter. The transmitter may use the largest sequence numbers for all links and its packet-to-link mapping to determine whether to quickly resend each missing packet or wait.

摘要： Systems and methods for dynamically adjusting the transmission time inter val (TTI) for a communications system are presented. The described aspects p rovide for dynamically adjusting the TTI in a communication session between a base station or nodeB and a wireless device or user equipment between a sh orter TTI, which can provide increased data throughput and lower power consu mption, and a longer TTI, which can provide more rugged communication link c onnections. By dynamically adjusting the TTI, the communications link can be optimized for the given communication channel conditions. Determinations, b ased on indicia related to the communications system conditions, can be empl oyed in dynamic TTI adjustment. These determinations can be formed centrally at the Radio Network Controller (RNC), at the RNC supplemented with user eq uipment (UE) available information, or formed in a distributed manner betwee n the RNC and UE across a communications system.

摘要： In a wireless communication system in which a user using a mobile equipment requests a serving cell handoff from a source cell to a target cell, the mobile equipment monitors authorization for the handoff from the target cell. At the same time, the mobile equipment can decode data from either the source cell or the target cell. Upon receipt of authorization for the handoff, the mobile equipment sends confirmation of the handoff to the target cell.

摘要： A method for delivering SMS to ATs in a first communication network providing DO and 1x interfaces and for offloading the delivery of the SMS from a second communication network including an MSC, comprising monitoring a DO control channel for pages by an AT and delivering the SMS in SIP to the AT over the DO interface. The method may further comprise tuning the AT to the DO interface and determining whether the AT is SIP registered for using the DO interface. An application server determines whether the AT is SIP registered for using the DO interface. When the DO interface is not available, the SMS may be delivered over the 1x interface and the method further comprises the AT sending a special SMS to an SMS gateway, which causes the application server to remember that the AT is now monitoring the first communication network including a circuit-switched network.

摘要： Embodiments described herein relate to connected-state radio session transfer in wireless communications. A source access network controller may lock a source radio session associated with an access terminal (e.g., in response to detecting a handoff condition associated with the access terminal), where the source access network controller may be in communication with a data network. The source access network controller may also instruct a target access network controller to create a target radio session corresponding with the source radio session, and to establish a communication route between the data network and the access network via the target ANC. The source access network controller may then freeze a state associated with the source radio session and transmits the frozen state to the target access network controller.; The target access network controller may subsequently unfreeze the received state and further unlock the radio session, hence resuming control of the access terminal.
