摘要： Systems and methodologies are described that facilitate resolving resource assignment conflicts between access terminals in a wireless communication environment. A first access terminal may receive a persistent, or “sticky” assignment of a set of resources, such as subcarriers. In the event that a second access terminal requires a brief resource assignment, a time-limited, or “non-sticky” resource assignment may be granted to the second access terminal. If a resource in the non-sticky assignment is already assigned to the first access terminal via the sticky assignment, the first access terminal may receive an indication of the conflict along with information related to a duration of the non-sticky assignment, may surrender the conflicted resource, and may resume control over the conflicted resource after the termination of the non-sticky assignment.

摘要： Methods and apparatus for communicating packets of information from an access terminal to a remote access node assembly by way of a serving access node assembly are described. An inter-route tunneling protocol module which interfaces with a radio link protocol module is used to tunnel route protocol packets. A first radio link protocol stream is associated with an application resident on the access terminal. A second radio link protocol stream is associated with an inter-route tunneling protocol module. Information to be communicated to a remote access node assembly by way of a serving access node assembly is subjected to two different radio link protocol processing operations. A first one of the RLP processing operations corresponds to the remote access node assembly while the second RLP processing operation corresponds to the serving access node assembly.

摘要： Methods and apparatuses are provided that include handing over relays in wireless networks. Handover request messages for a relay and related user equipment (UE) can be grouped to lessen signaling requirements for handover. Moreover, identifiers can be communicated in the messages to optimize bearer establishment at a target base station to which the relay and related devices are handed over. Also, handover exception cases can occur, which can be handled by the relay and source and target base stations, such as bearer rejection at the target base station, handover failure for one or more devices or the relay, and/or the like. Further, handover of a relay can occur between base stations that house one or more network gateways for the relay, or where the gateways are centralized and accessible by the source and target base stations, where each scenario can include different exception handling.

摘要： Methods and apparatus for communicating between an access terminal (AT) and an Access Point (AP) are described. For communications over the air link, between an AP and an AT a PN (Pseudo-random Noise) code based address is used as an AP identifier, e.g., address. The PN code based address may be based on Pilot PN code based signals received from an AP. Thus, the PN based AP address may be determined from pilot signals received from an AP. The PN based AP address may be a shortened version of a PN code corresponding to an AP, a full PN code corresponding to an AP, or a value which can be derived in a known manner from a PN code corresponding to an AP.

摘要： Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for measuring signal strength of an alternative frequency by tuning away from an existing frequency associated with an existing communications path. Such processes allow determining if the alternative frequency supports a subsequent communications path in a mobile broadband wireless application. Upon the determination, the process can automatically select the subsequent communications path based in part on the measured signal strength.

摘要： Systems and methodologies are described that facilitate compressing headers for relay nodes. In particular, a plurality of internet protocol (IP) headers, tunneling protocol headers, and/or other routing headers in a packet can be compressed to facilitate efficient communications of packets between relay nodes and/or a donor access point. An access point receiving packets to be compressed can provide a disparate access point with a compression context and an uncompressed packet. The disparate access point can generate a decompression context related to subsequent packets having similar header values and can store the decompression context with the context identifier. The access point can subsequently compress received packets having similar header values and communicate the compressed packets with the context identifier to the disparate access point. The disparate access point can apply the previously generated decompression context associated with the context identifier to decompress the packets.

摘要： Systems and methods are disclosed to enable multiple neighbour base stations or access points (APs) preparation for handover robustness. The systems and methods include generating a handover request message at a source base station (BS) for user equipment (UE) if the UE detects at least one neighbour BS. The handover request message may include a handover imminent flag. The handover request message is transmitted to the neighbour BS, wherein if the handover imminent flag indicates that the handover is not imminent, the neighbour BS does not reserve a radio network temporary identifier (RNTI) for the UE.
