Abstract:
Systems and methodologies are described that facilitate multiple-phase selective connection establishment in wireless communications networks. Radio resource control (RRC) layer communications can be instantiated between a mobile device and base station. Additional information can be required by a downstream network component regarding the mobile device. Accordingly, the RRC resources can be utilized to transmit the additional information from the mobile device to the network component to facilitate the multiple-phase establishment. This can be accomplished using non-access stratum (NAS) messages. Further, the information can relate to authorization, security re-configuration, context re-synchronization, an identity of the mobile device, and the like.

PROBLEM TO BE SOLVED: To provide techniques to support operation of user equipment (UE) in a compressed mode and a CPC mode.SOLUTION: The UE obtains assignment of enabled subframes for the CPC mode and assignment of transmission gaps for the compressed mode. The transmission gaps are aligned with idle times between the enabled subframes. The UE exchanges data during enabled subframes not overlapping the transmission gaps and skips data exchanges during enabled subframes overlapping the transmission gaps. The UE makes cell measurement during the transmission gaps. The UE obtains enabled subframes and skipped subframes, exchanges data during enabled subframes not corresponding to the skipped subframes, and skips data exchanges during the skipped subframes. The UE receives orders on a shared control channel to quickly enable and disable the compressed mode.

PROBLEM TO BE SOLVED: To provide techniques for synchronizing sequence numbers so as to re-order packets properly at handover.SOLUTION: A transmitter ciphers each input packet with a full sequence number. The transmitter generates output packets for the ciphered packets. Each output packet includes a partial sequence number used for re-ordering and derived from the full sequence number. The full sequence number may be incremented for each input packet or each byte of each packet. The partial sequence number may be used as a sequence number for RLC and may be used for re-ordering, duplicate detection, error correction, and/or other functions. A receiver performs the complementary processing, re-orders received packets based on the partial sequence number included in each packet, and ciphers the received packets using the partial sequence number included in each received packet.
Abstract:
PROBLEM TO BE SOLVED: To provide a method of enabling user terminal (UT) access to wireless networks having disparate types of base stations (BSs).SOLUTION: A distinct identifier (ID) is reserved for a particular type of network access point. The distinct ID is broadcasted by such access points, identifying the access point type. In some aspects, the distinct ID is unicast to a terminal that is within a predetermined region of the network. Thus, at least within such region, the terminal can be directed to search for or handoff to a preferred type of access point. In such aspects, by providing regional-specific access, the subject disclosure can significantly reduce overhead signaling outside a home region where a home or preferred access point is expected to be found.
Abstract:
PROBLEM TO BE SOLVED: To provide a method and device for reducing interference in a wireless communication system when a source of the interference is a decisive component of the system. SOLUTION: A receiver classifies the weight of a transmitter according to when the source of interference is transmitted. The transmitter can use power boosting in order to overcome the source of interference. A W-CDMA system transmits a synchronous channel to a physical channel. Here, the synchronous channel is not orthogonal to the physical channel. The receiver cancels the synchronous channel on receiving control or data information. Similarly, the receiver classifies the weight of the transmitter among a plurality thereof. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To make it possible to trust in arrival timing of a symbol from each cell and determine which symbol should be compounded at the time of software hand-off operation. SOLUTION: After down link data frame time offset is determined, a mobile station 101 is informed about the down link data frame time offset, by transmitting the down link data frame time offset through an active set renewal message, which is transmitted from a cell 102 or a cell 103 to the mobile station 101. Once the active set renewal message is received, the data frame time offset information is fed to a timing block, and thereby data frame border of each down link signal is determined. The timing block adjusts PN sequence timing corresponding to the down link signal in relation to the data frame time offset so that the corresponding data symbol in each data frame can be subjected to software composition correctly in a compositor.

Abstract:
PROBLEM TO BE SOLVED: To provide an inter-system handover system that efficiently supports hand-down and hand-up to different radio access technologies.SOLUTION: Latency and handover connection failures are reduced by an access node (nodeB) broadcasting information about a neighboring system (target) when a UE 12 reception (RX) capability is both inside and outside a reception range of the neighboring system. A optimized list of neighboring RAT systems (targets) are broadcast from a network, including measurement parameters and reporting instructions. Thereby, reporting driven by the UE 12 minimizes the latency. The UE 12 reports other-system searches to network only if needed for a handover. In addition, handover requests can be bundled with other system measurement information, if necessary, for additional efficiency.
Abstract:
PROBLEM TO BE SOLVED: To provide methods and apparatus for broadcasting content.SOLUTION: In encoding the content to be multicast/broadcast into multiple streams, at least one stream provides a base portion of the content, and additional streams provide enhancements to the content. A wireless communication device receives the broadcast and decodes streams in accordance with the reception capabilities of the wireless device. The configuration of the wireless device can be determined based on the wireless device's capability to decode multiple streams. In addition, the configuration of the wireless device can be determined based on a subscriber level of the wireless device.

Abstract:
PROBLEM TO BE SOLVED: To provide techniques for efficiently configuring and reconfiguring calls using default configurations and differential encoding.SOLUTION: At the network side, a configuration to use for communication with a wireless device is initially selected (512). A default configuration is identified from among a set of default configurations (520). The differences, if any, between the selected configuration and the default configuration are ascertained (522). An identity for the default configuration and the differences, if any, is sent to the wireless device to convey the selected configuration (530). At the wireless device, the message containing the identity for the default configuration is initially received.
