Abstract: Systems and methodologies are described that facilitate processing service data units (SDU) in-order during communication handover in wireless networks. In particular, for mobile devices using retransmission schemes, SDUs can be processed in-order by indicating to a target base station an index of a last SDU received in-order before handing off communication to the target base station. Additionally, SDUs received subsequent to one or more non-acknowledged SDUs can be forwarded to the target base station. Utilizing this information, the target base station can determine one or more SDUs the mobile device is preparing to re-transmit and can wait for this SDU before processing subsequently received SDUs. Also, a timer can be utilized to end a waiting period for the SDU.

Abstract: Systems and methods are provided for a learning-based determination of semi-persistent scheduling of data-packet flow wireless communication. A packetized data flow served to a wireless terminal is fully scheduled for an initial period of time in order to collect statistics associated with scheduled packet sizes (Ss) and inter-packet times (Ts). Analysis of a cumulative distribution of {S, T} pairs indicate whether a characteristic packet size (S0) and size dispersion (D0) are associated with the cumulative distribution. Inter-time intervals associated with the characteristic size and dispersion complete a transport format. Semi-persistent scheduling is utilized for a packetized flow when a characteristic transport format can be extracted, or learned, from the accumulated statistics. Extracted transport formats can be employed to optimize scheduling efficiency upon handover.

Abstract: Techniques for sending a message for random access by a user equipment (UE) are described. In an aspect, the UE may send the message on a control channel for random access and may send a reserved channel identifier to indicate the message being sent on the control channel. In another aspect, the UE may send the message in a protocol data unit (PDU) and may send additional information (e.g., a buffer status report) in the PDU if it can accommodate the additional information. In yet another aspect, the UE may generate a short message authentication code for integrity protection (MAC-I) for the message. The short MAC-I may have a smaller size and may be used to authenticate the UE. In yet another aspect, the UE may send a UE ID of one of multiple types for random access and may convey the UE ID type via a format field in the message.

Abstract: Systems and methodologies are described herein that facilitate techniques for managing respective original transmissions and re-transmissions of information within a wireless communication system. Various mechanisms are described herein for processing a new data indicator (NDI) associated with respective transmissions con-ducted for one or more Hybrid Automatic Repeat Request (HARQ) processes. For example, for a HARQ process shared between distinct scheduling schemes, an NDI associated with a latter transmission can be regarded as toggled irrespective of the value of the NDI upon recognizing that a utilized scheduling scheme (e.g., as indicated via a radio network temporary identifier (RNTI) or the like) has changed between successive transmissions (e.g., from semi-persistent scheduling to dynamic scheduling), thereby allowing processing of the latter transmission as a transmission of new data. As additionally described herein, various techniques are described herein for NDI processing in the case of uplink grant and downlink assignment transmission.

Abstract: A method as well as an apparatus for transmitting data from a local transmitter (12, 500) to a remote receiver (14, 600) is described, the method comprising transmitting a radio link control command (16, 17, 18) from the local transmitter (12, 500) to the remote receiver (14, 600), transmitting a polling command (34) without requiring transmission of user-plane data in response to detecting a polling event, wherein transmitting the polling command (34) comprises transmitting a protocol data unit with zero-length data and a header portion of a previously transmitted protocol data unit and receiving a status protocol data unit (38) from the remote receiver (14, 600). Also, a corresponding receiving method and apparatus is described.

Abstract: Embodiments disclosed herein for MAC processing for efficient use of high throughput systems and that may be backward compatible with various types of legacy systems. In one aspect, a data transmission structure comprises a consolidated poll and one or more frames transmitted in accordance with the consolidated poll. In another aspect, a Time Division Duplexing (TDD) data transmission structure comprises a pilot, a consolidated poll, and zero or more access point to remote station frames in accordance with the consolidated poll. In one aspect, frames are transmitted sequentially with no or substantially reduced interframe spacing. In another aspect, a guard interframe spacing may be introduced between frames transmitted from different sources, or with substantially different power levels. In another aspect, a single preamble is transmitted in association with one or more frames. In another aspect, a block acknowledgement is transmitted subsequent to the transmission of one or more sequential frames.

Abstract: Confusion resulting from assigning the same node identifier to multiple nodes is resolved through the use of confusion detection techniques and the use of unique identifiers for the nodes. In some aspects a network may provide a time gap (e.g., an asynchronous time gap) during which an access terminal may temporarily cease monitoring transmissions from a source node so that the access terminal may acquire a unique identifier from a target node. In some aspects an access terminal may commence handover operations at a target node after determining whether the access terminal is allowed to access the target node. In some aspects a source node may prepare several target nodes for potential handover in the event confusion is detected or likely. Here, the source node may send information relating to the preparation of the potential target nodes to the access terminal whereby the access terminal uses the handover preparation information to initiate a handover at that target node.

Abstract: Methods and apparatus for determining the quality of service of a network are disclosed. A disclosed methodology for determining quality of service for a network includes determining at least two metrics reflective of network parameters in at least two different protocol layers of the communication network. The metrics are then compared with respective threshold values, and quality of service for the network is determined based on the comparison of the metrics with the respective threshold values. Corresponding apparatus executing the methodology are also disclosed.
