This disclosure provides a method and apparatus for the communication of low delay data over multiple channels having different speed and latency and requiring a different amount of time to set up. In one embodiment, the transmitter removes duplicate data packets from a queue after a second channel, such as a dedicated channel is established. In an alternate embodiment, sequence numbers are assigned to data packets, allowing the receiver to identify duplicate packets and ignore the duplicates.

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.

A method and system for providing asymmetric modes of operation in multi-carrier wireless communication systems. A method may assign a long code mask (LCM) to an information channel associated with a plurality of forward link carriers to transmit data from an access network to an access terminal; and multiplex the information channel on a reverse link carrier. The information channel may include one of data source channel (DSC), data rate control (DRC) and acknowledgment (ACK) information, and the multiplexing may be code division multiplexing (CDM). The AN may instruct the AT on whether to multiplex the DSC information based on feedback from the AT. The method may further offset the ACK information on the reverse link to reduce the reverse link peak to average, CDM the information channel on an I-branch and on a Q-branch, and transmit the code division multiplexed information channel on the reverse link carrier.

Embodiments disclosed herein relate to methods and systems for grouping pilot signals and using such grouping for pilot strength reporting and set management in multi-carrier communication systems. In one embodiment, an access network may assign a group identifier (or “group ID”) to each of the pilot signals associated with the sector, e.g., based on the coverage areas of the pilot signals, and transmit the pilot signals with the corresponding group IDs. PN offset may be used as the group ID. An access terminal may group the pilot signals received into one or more pilot groups in accordance with their group IDs, and select a representative pilot signals from each pilot group for pilot strength reporting. The access terminal may also use the pilot grouping to perform effective set management.

Aspects describe separate caches that can be utilized to retain overhead information while device is in idle mode. A first cache can be associated with a first timer and can be utilized when a device is performing idle handoff. A second cache, associated with a second timer can be utilized when a device is not performing idle handoff. Second timer can have a longer period of validity than first timer. The separate caches can be utilized in networks that include femto cell topography, wherein re-use of pilot PN codes are at a greater frequency than the re-use frequency in macro cell topography.

Systems and methodologies are described herein that facilitate congestion control in a wireless communication system. As described herein, an access network and associated terminals can utilize a token bucket access control mechanism, through which respective terminals can be allotted access tokens and/or other units for access to the access network. For example, upon requesting access to a given network, a user of the network can determine whether sufficient access tokens have been accumulated, based on which the request can be selectively allowed or denied. As further described herein, multiple token bucket mechanisms can be utilized, which can correspond to respective packet flows or the like. Additionally, token bucket access control can be implemented as described herein in cooperation with conventional access persistence functionality. Further aspects described herein facilitate the adjustment of token bucket parameters for network access control based on network loading.

A method and apparatus for obtaining content with reduces round trip times is provided. The method may comprise transmitting, from a device, a primary content item request to a proxy server to obtain a primary content item using a first protocol, receiving the primary content item from the remote proxy using the first protocol, generating one or more secondary content item requests for one or more secondary content items associated with the primary content item, transmitting the one or more secondary content item requests to the proxy server using a second protocol, wherein the second protocol decouples the one or more secondary content item requests from an acknowledgement of receipt of the one or more secondary content item requests, and receiving at least one of the one or more secondary content items from the proxy server using the second protocol.
