PROBLEM TO BE SOLVED: To provide systems and methods that facilitate sharing of bandwidth between a wide area network and a local area peer-to-peer network.SOLUTION: The peer-to-peer network may use an air interface technology that is the same as or distinct from an air interface technology used in the wide area network. Moreover, the wide area network and the local area peer-to-peer network may utilize distinct sets of parameters. For example, if the wide area network and the peer-to-peer network use OFDM-based air interface technologies, parameters such as tone spacing, symbol time and cyclic prefix of the two networks may vary. Further, peer-to-peer parameters may be a function of parameters for the wide area network.

PROBLEM TO BE SOLVED: To provide a method of transmitting broadcast information in a wireless communication system.SOLUTION: Systems and methodologies (1600) are described that facilitate transmitting at least two different types of information in a single signal, thereby allowing independent encoding and decoding of the different types of information. Thus, change in one type of information does not affect a second type of information.
Abstract:
PROBLEM TO BE SOLVED: To provide methods and terminals for paging the terminals in a wireless (e.g., OFDMA) communication system to achieve both fast paging response and low power consumption for the terminals.SOLUTION: A terminal receives paging indicator from a base station. If the paging indicator indicates that the terminal is potentially being paged, then the terminal receives at least one paging message from a paging channel. The terminal determines whether any one of the at least one paging message is for the terminal, e.g., on the basis of identification information included in each paging message. If a paging message indicates that the terminal is paged, then the terminal sends an acknowledgement for the paging message.

PROBLEM TO BE SOLVED: To provide a method and an apparatus of wireless communications, more specifically, a method and an apparatus for implementing a dedicated control channel and using the dedicated control channel.SOLUTION: Wireless terminals and base stations support multiple modes of dedicated control channel operation, where different amounts of dedicated uplink resources for reporting control information are allocated to the wireless terminals. A set of dedicated control channel segments is utilized by the wireless terminals to communicate uplink control information reports to serving base station attachment points. Full tone and split-tone modes of dedicated control channel operation are supported. In the full tone mode, each of the dedicated control channel segments associated with a single logical tone is allocated to a single wireless terminal. In the split tone mode, dedicated control channel segments associated with a single logical tone are allocated between different wireless terminals.
Abstract:
PROBLEM TO BE SOLVED: To provide methods and apparatus for an efficient two-stage paging wireless communication system.SOLUTION: Wireless terminals are assigned to paging groups. A few first paging message information bits are modulated (using asynchronous modulation) into a first paging signal and communicated from a base station to a wireless terminal. WT wakes up, receives the first paging signal and quickly checks whether its paging group should wait for a second paging signal. If so, the WT is operated to receive the second paging signal; otherwise, the WT goes back to sleep conserving power. The base station modulates several second message information bits (using synchronous modulation) and transmits signals to WTs. From the information in the first and second paging signals, a WT can determine that it is the paged WT and process the paging instructions. The intended paged WT can transmit a reception acknowledgement signal on a dedicated uplink resource.
Abstract:
PROBLEM TO BE SOLVED: To provide methods and apparatus for routing messages between an end node and an access node via another access node.SOLUTION: Physical layer identification information is used when identifying a remote, e.g., adjacent, access node as a message destination. Thus, when a connection identifier based on one or more physical layer identifiers is available to a wireless terminal, e.g., from one or more downlink signals received from a destination access node, the wireless terminal can use the connection identifier corresponding to the destination node to route a message via an access node having an established uplink connection. Such connection identifier information can be used even when other addressing information, e.g., network layer address information, associated with the destination access node, may not be available to the wireless terminal.
Abstract:
PROBLEM TO BE SOLVED: To support multiple communication channels corresponding to different communication technologies and/or access technologies in parallel within a cell of a wireless communications system. SOLUTION: Mobile nodes support multiple technologies and can switch between the technology being used at a particular point of time, e.g., from a first channel corresponding to a first technology to a second channel corresponding to a different technology which provides better transmission characteristics, e.g., a better perceived channel quality. Mobiles maintain at least two sets of channel quality information at any one point of time. Mobiles select the better channel and communicate the channel selection to a base station or communicate channel quality information for multiple channels to the base station and allow the base station to select the channel corresponding to the technology providing the better conditions for the mobile. Different mobiles in the same cell may support different technologies. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide pilot signal transmission sequences and methods for use in a multi-sector cell. SOLUTION: Pilots in different sectors are transmitted at different known power levels. In adjacent sectors, a pilot is transmitted while no pilot is transmitted in the adjoining sector. This represents transmission of a null pilot signal. A cell null is also supported, in which null pilots are transmitted in each sector of a cell at the same time. Measurements of multiple pilot signals are performed. At least two channel quality indicator values are generated from measurements corresponding to at least two pilot signals of different power levels. Two values are transmitted back to a base station which uses both values to determine the transmit power required to achieve a desired SNR at the wireless terminal. The wireless terminal also reports information indicating its location to a sector boundary. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate assigning a flow (e.g., IP flow) to a wireless network link from a bundle that includes a plurality of wireless network links.SOLUTION: Assignments can be based upon characteristics associated with the flow and upon characteristics associated with the links. For example, a service class corresponding to the flow can be evaluated to determine flow related characteristics. Moreover, link related feedback can be analyzed to determine characteristics of the links.

The tone spacing for a first type symbol is larger than the tone spacing for a second type symbol.
