Described herein are mechanisms and methods that facilitate seamless handoff of an access terminal between access points (transceiver modules). A first transceiver module can be providing forward link data services to an access terminal when it requests a handoff to a second transceiver module. In response, the first transceiver module can provide data that is desirably transmitted to the access terminal to the second transceiver module. A network module can inform a plurality of transceiver modules that the second transceiver module is servicing the access terminal, and can further provide data to the second transceiver module for transmittal to the access terminal.

To support mobile stations that are not capable of demodulating the entire bandwidth or that can be made to demodulate less than the entire bandwidth, a system, apparatus and method are provided to schedule users on less than all of the bandwidth. Further, certain users can be scheduled on more of the bandwidth than others.

Receiver diversity in a wireless device is controlled in response to operating conditions, transmission requirements, and control settings. The control of diversity reduces power consumption by enabling receive diversity on given conditions. Operating conditions, transmission requirements, and control settings are used separately or used in conjunction to determine whether benefits of multi-antenna receive diversity, such as higher link capacity, higher data throughput, lower transmit power, and lower error rate, warrant the higher power cost of the diversity.

A resource assignment method during a tune-away procedure comprises determining a first instance in time that a tune-away will initiate with respect to an access terminal, determining a second instance in time that corresponds to a latest frame boundary associated with the access terminal prior to the instance in time that the tune-away initiates, and determining resource assignment parameters associated with the access terminal and implementing the resource assignment parameters at the second instance in time. The method can further comprise ceasing communications to the access terminal over a forward link at the second instance in time and discontinuing monitoring reverse link control channels associated with the access terminal at the second instance in time.

Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

Methods and apparatus for processing and generating broadcast messages determined by a subband and OFDM symbols of frames in which signals are received. Overhead messages indicating resources used by broadcast messages in a wireless communication system are generated. Signals are received over a wireless system and broadcast messages are determined from the signals as designated by a subband and OFDM symbols of frames of an ultraframe in which signals are received.

Systems and methodologies are described that facilitate packet routing among relay eNBs in a wireless network. Packet data convergence protocol (PDCP) layer communications from a user equipment (UE) can terminate at a donor evolved Node B (eNB) and vice versa. In this regard, a relay application protocol (RAPP) layer is defined to transport application layer control data among relay eNBs to facilitate appropriate routing. RAPP layer messages can be similar to control messages at other application layers, such as S1-AP, X2, etc., while additionally including a relay UE identifier for routing the messages among relay eNBs. In addition, RAPP layer messages can exclude other parameters normally defined in other application layers to protect security and encryption/decryption details.

Paging and power consumption are managed in conjunction with providing local breakout in a wireless wide area network. In some aspects, if a packet destined for an access terminal is received at an access point that provides local breakout, the access point may inform the network so that the network will cause the access point to page the access terminal. Alternatively, in some aspects an access point that provides local breakout may maintain idle context of the access terminal, whereby the access point may autonomously page the access terminal (i.e., without involving the core network). In some aspects local breakout traffic is filtered at an access point to reduce the number of pages or packets sent to an access terminal. In some aspects an indication of a packet type is provided with a page message to enable an access terminal to determine whether to receive the packet. In some aspects a local link interface may be selectively disabled or enabled to limit traffic at an access terminal.

Techniques for sending control information in the header of multiple packets are described. The techniques may allow more control information to be sent using a small number of overhead bits per packet. In one design, a first node (e.g., a network entity) may determine control information to send to a second node (e.g., a UE or another network entity). The first node may send the control information in the header of multiple packets toward the second node. In one design, the control information may include congestion information indicative of traffic congestion at the first node. The congestion information may be sent using Explicit Congestion Notification (ECN) bits in the header of IP packets. The first node may send the control information with or without coding and for all packets or a specific data flow. The first node may also send a synchronization sequence prior to the control information.

Described herein is methodologies for efficient utilization of backhaul resources of a network for delivering paging data to an access terminal (AT) without sacrificing delay performance. A location that buffers data for an AT can be adaptively changed based on factors such as the location of the AT, applications utilized by the AT, and a recent activity level of the AT. To facilitate this determination, an AT can be configured with one or more registration boundaries. An AT can be configured with a small registration radius such that if the AT does not move outside of the small registration radius, data can be delivered directly to a data attachment point for the AT. If the AT moves outside of the small registration radius, the registration radius can be switched to a large registration radius and the access gateway can instead locally buffer data for the AT.
