Abstract: TECHNIQUES FOR SENDING A MESSAGE FOR RANDOM ACCESS BY A USER EQUIPMENT (UE) (120) ARE DESCRIBED. IN AN ASPECT, THE UE (120) 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 (120) MAY SEND THE MESSAGE IN A PROTOCOL DATA UNIT (PDU) (600,810,820) AND MAY SEND ADDITIONAL INFORMATION (E.G., A BUFFER STATUS REPORT) IN THE PDU (600,810,820) IF IT CAN ACCOMMODATE THE ADDITIONAL INFORMATION. IN YET ANOTHER ASPECT, THE UE (120) 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 (120). IN YET ANOTHER ASPECT, THE UE (120) 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: Methods and apparatus are described comprising receiving, at a station, a slow delivery traffic identification message, DTIM, sent at a slower rate than a regular DTIM, with the regular DTIM indicating first broadcast and multicast traffic and the slow DTIM indicating second broadcast and multicast traffic; and receiving the second broadcast and multicast traffic as indicated by the slow DTIM.

Abstract: Systems and methodologies are described that facilitate utilizing hybrid automatic repeat/request (HARQ) in system access communications. A HARQ entity is provided that manages a plurality of HARQ processes, which can typically use new data indicators (NDI) to determine when received data is a new transmission or retransmission. For resource grants, the HARQ entity can determine whether the communication is a new transmission or retransmission based on the type of message that contains the grant. In addition, an address comprised within the message, a previous use of the HARQ process, and/or the like can further be utilized to determine whether the message is a new transmission or retransmission. Once determined, the HARQ entity can provide the message to the appropriate HARQ process along with the indication of new transmission or retransmission.

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: Transmit power is controlled for a first uplink data transmission on Physical Uplink Shared Channel (PUSCH) during random access channel (RACH) procedure. Power control adjustment for the first PUSCH transmission is performed relative to the power spectral density used for successful PRACH transmission as adjusted for bandwidth difference, etc. The uplink Physical random access channel carries the RACH information that is transmitted by the user equipment (UE) during registrations or base station originated calls. A PRACH is composed of a number of preambles and a message portion. The preambles are a series of radio frequency power "steps" that increase in power according to the power step setting until the maximum number of preambles is reached or the base station acknowledges. Once the UE receives a positive indication, it transmits the message portion of the PRACH which consists of message data and control data with independent power gain control.

Abstract: Systems and methodologies are described that facilitate increased communication channel bandwidth efficiency in association with scheduled time periods that allocate channel access to particular stations. According to various aspects, systems and methods are described that facilitate providing and/or utilizing reverse direction grants in connection with scheduled channel access. Such systems and/or method can mitigate an amount of unused channel access time after a station completes data transmission prior to an end of the allocated period.

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 re-transmission 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.
